Breath hydrogen excretion over a period of three hours was measured to evaluate carbohydrate malassimilation in healthy cats treated orally with antibiotics. Both an absorbable carbohydrate (xylose) and a non-absorbable carbohydrate (lactulose) were administered during the tests to evaluate the changes in the intestinal mucosa and the population of bacteria within the intestinal lumen. Overall, the effects of oxytetracycline and metronidazole on breath hydrogen excretion were not significantly different. However, the treatment effect with an antibiotic did significantly change breath hydrogen excretion after xylose administration (P<0.05) within groups. Similarly, with each antibiotic, breath hydrogen excretion was affected significantly (P<0.001) by the time after the administration of the carbohydrate. Treatment with each antibiotic also interacted significantly with this time effect (P<0.05) within groups. After lactulose administration, there was a trend within groups for the ...

Rich hydrogen products are dazzling, each said good, consumers are difficult to adapt. Effective and safe hydrogen-rich products must: 1, the concentration of 1200ppb or more, 2, no chemical by-products, such as SPE membrane electrolysis hydrogen. 3, must be made of molecular hydrogen, hydrogen and oxygen separation technology. 4. Instantaneous hydrogen production and continuous hydrogen production are the most reliable. 5. Heating function is critical.. According to the drinking hydrogen water standard issued by the International Hydrogen Standards Committee (IHSA), the hydrogen content of the hydrogen-rich water machine must be above 1200 pp, which is 1.2 ppm or more. Any hydrogen-rich water machine smaller than this data is ineffective for the human body. Some merchants may say that his machine has a hydrogen content of only 300 ppb, but he can absorb more hydrogen by drinking more than 3 liters of water a day. Medical research has shown that drinking water below 1200 ppb is not beneficial to ...
To our knowledge, this is the first report demonstrating the benefits of drinking hydrogen water in patients receiving radiation therapy for malignant tumors. This finding may provide the foundation for a clinically applicable, effective, and safe strategy for the delivery of hydrogen gas to mitigate radiation-induced cellular injury. Patients experience GI symptoms and decreased QOL during radiotherapy. These symptoms usually occur as a result of the body repairing damage to healthy cells, are particularly common towards the end of a course of radiation treatment, and can last for some time. The symptoms and their impact on QOL can be worsened by having to travel to the hospital each day. Drinking hydrogen-rich water improved the QOL of the patients receiving radiotherapy and did not require additional hospital visits. Although overall survival of patients with malignant tumors should remain oncologists primary concern, survival should also be interpreted in light of symptom palliation and ...
Crude glycerol (CG) is the main by-product (waste) of biodiesel production (by transesterification of lipids) and by weight it could be as high as 10% (w/w) of the final product. Considering global interest for biodiesel production, there is a need for sustainable management of the waste. In this context, bio-hydrogen production by utilization of CG could be an interesting option. Moreover, hydrogen is considered as the cleanest renewable alternative of fossil fuels. However, CG contains a few impurities, such as methanol, NaCl and soap and their individual and interactive effect on hydrogen production should be investigated. Thus, present study deals with the investigation of the effect of methanol, NaCl and soap on hydrogen production and substrate (glycerol) utilization. Based on the investigation carried out using response surface methodology, it was observed that soap is the most significant factor (p value=0.0104,0.05) to inhibit hydrogen production. Similarly, methanol was also found to ...

A method of operating a H2-O2 fuel cell fueled by hydrogen-rich fuel stream containing CO. The CO content is reduced to acceptable levels by injecting oxygen into the fuel gas stream. The amount of oxygen injected is controlled in relation to the CO content of the fuel gas, by a control strategy that involves (a) determining the CO content of the fuel stream at a first injection rate, (b) increasing the O2 injection rate, (c) determining the CO content of the stream at the higher injection rate, (d) further increasing the O2 injection rate if the second measured CO content is lower than the first measured CO content or reducing the O2 injection rate if the second measured CO content is greater than the first measured CO content, and (e) repeating steps a-d as needed to optimize CO consumption and minimize H2 consumption.

High-resolution core-level spectroscopy (HRCLS) and density functional theory (DFT) calculations have been used to investigate the adsorption and dissociation of hydrogen on a PdO(101) film grown on Pd(111). Energy-dependent measurements of the O 1s and Pd 3d(5/2) binding energies enable identification of surface components that correspond to undercoordinated Pd and O atoms. HRCLS data obtained at 110 K, after hydrogen exposure at the same temperature, reveal hydrogen adsorption and formation of Pd-H and O-H groups. Adsorption at room temperature results instead in complete reduction of the oxide. The experimental results are supported by the DFT calculations of core-level shifts and barriers for water formation.

Oxidative stress is one of the main causes of AMD. Hydrogen has anti-oxidative stress and apoptotic effects on retinal injury. However, the effect of hydrogen on AMD is not clear. In this study, fundus radiography, OCT, and FFA demonstrated that HRW reduced the deposition of drusen-like structures in RPE layer, prevented retina from thinning and leakage of ocular fundus vasculature induced by NaIO3. ERG analysis confirmed that HRW effectively reversed the decrease of a-wave and b-wave amplitude in NaIO3-mice. Mechanistically, HRW greatly reduced the oxidative stress reaction through decreased MDA levels, increased SOD production, and decreased ROS content. The OGG1 expression was downregulated which is a marker of oxidative stress. Involvement of oxidative stress was confirmed using oxidative stress inhibitor ALCAR. Moreover, oxidative stress reaction was associated with expression of Sirt1 level and HRW significantly inhibited the downregulation of Sirt1 expression. This result was further confirmed
Buildup of unreacted hydrogen gas in sealed electrochemical cells has been prevented by inserting a hydrogen absorbing device into the cell before sealing. This hydrogen absorbing device is preferably a discrete shaped body, e.g., cylindrical or ring shaped, encased in an electrolyte impermeable, but hydrogen gas permeable membrane and includes a material which will react chemically with hydrogen gas, a catalyst for the hydrogen consuming reaction, and a compatible binder which maintains the reactant and catalyst in the form of a discrete shaped body which is porous to hydrogen gas.

Sanchez-Torres et al. obtained by random mutagenesis several mutants of the transcriptional factor gene fhlA in which hydrogen gas production is enhanced.[1] Among these mutants, the E363G mutation allowed E.coli cells to produce hydrogen six times more than the original fhlA under anaerobic conditions with 20 mM formate. Therefore, we made a BioBrick part named fhlA -E363G by introducing the same mutation into the original wild type fhlA gene which we BioBricked. Our aim is to make E. coli cells which are capable of producing hydrogen in a glucose-rich environment.Hydrogen production was elevated in the fhlA overexpression cells compared to the wild type. In an attempt to further increase hydrogen production, we compared the hydrogen production of two E. coli strains which over-expresses wild-type fhlA and fhlA -E363G in a glucose-rich environment. As a result, the fhlA -E363G expressing strain generated less hydrogen gas than the wild type fhlA expressing strain. It is considered that under ...
Hydrogen is the simplest element. Each atom of hydrogen has only one proton. Hydrogen is also the most plentiful gas in the universe. Stars like the sun consist primarily of hydrogen.. The sun is essentially a giant ball of hydrogen and helium gases. In the suns core, hydrogen atoms combine to form helium atoms. This process-called fusion-gives off radiant energy.. The radiant energy from the sun gives earth light and helps plants grow. Radiant energy is stored as chemical energy in fossil fuels. Most of the energy that people use today originally came from the suns radiant energy.. Hydrogen as a gas (H2) is not found by itself on earth. Hydrogen gas is found only in compound form with other elements. Hydrogen combined with oxygen is water (H2O). Hydrogen combined with carbon forms different compounds like methane (CH4), coal, and petroleum. Hydrogen is found in all growing things and is an abundant element in the earths crust.. Hydrogen has the highest energy content of any common fuel by ...
In this perspective article we describe recent infrared spectroscopic investigations of mass-selected M+-H2 and M+-D2 complexes in the gas-phase, with targets that include Li+-H2, B+-H2, Na+-H2, Mg+-H2, Al+-H2, Cr+-D2, Mn+-H2, Zn+-D2 and Ag+-H2. Interactions between molecular hydrogen and metal cations play a key role in several contexts, including in the storage of molecular hydrogen in zeolites, metal-organic frameworks, and doped carbon nanostructures. Arguably, the clearest view of the interaction between dihydrogen and a metal cation can be obtained by probing M+-H2 complexes in the gas phase, free from the complicating influences of solvents or substrates. Infrared spectra of the complexes in the H-H and D-D stretch regions are obtained by monitoring M+ photofragments as the excitation wavelength is scanned. The spectra, which feature full rotational resolution, confirm that the M+-H2 complexes share a common T-shaped equilibrium structure, consisting essentially of a perturbed H2 molecule
Hydrogen could be an important source of clean energy, and the cleanest way to produce hydrogen gas is to split water into hydrogen and oxygen. But the catalyst currently used to facilitate this water-splitting reaction is platinum. And thats a problem.. When an electric current is run through water, it can split some of the water molecules. A catalyst lowers the amount of energy needed to split those molecules, and platinum is really, really good at this.. But platinum is also really, really expensive - much too expensive for widespread use in hydrogen production.. So, researchers have long viewed molybdenum sulfide (MoS2) as a promising, much cheaper alternative to platinum. The drawback is that MoS2s catalytic performance is far worse than platinums. To get around that problem, researchers have been trying to find ways to improve MoS2s catalytic performance. And now they may be on to something.. "The biggest stumbling block to improving MoS2s performance has been a lack of understanding ...

Recently, transition metal dichalcogenides (TMDs), represented by MoS2, have been proven to be a fascinating new class of electrocatalysts in hydrogen evolution reaction (HER). The rich chemical activities, combined with several strategies to regulate its morphologies and electronic properties, make MoS2 very attractive for understanding the fundamentals of electrocatalysis. In this review, recent developments in using MoS2 as electrocatalysts for the HER with high activity are presented. The effects of edges on HER activities of MoS2 are briefly discussed. Then we demonstrate strategies to further enhance the catalytic performance of MoS2 by improving its conductivity or engineering its structure. Finally, the key challenges to the industrial application of MoS2 in electrocatalytic hydrogen evolution are also pointed out.
It is a technology that produces the hydrogen gases by using only the microorganism and sunlight from the wastewater to be at a loss because of processing. And, the produced hydrogen uses the fuel cell and is used to generate electricity. Because this technology doesnt use the organic matter that becomes food, and use the organic matter included in waste, clean power generation is possible. We researched the improvement of the hydrogen gas production efficiency. The purple non-sulfur photosynthesis bacillus was purely cultured, the substrate dependency was clarified, and the best substrate dosage was decided. Moreover, it was shown that the light wave length conversion net was effective for the hydrogen gas production efficiency improvement. On the other hand, a too strong light intensity showed becoming the growth obstruction of phototropic bacteria. When the light intensity for the photosynthesis is insufficient, the light wave length conversion net can support this. On the other hand,

Hydrogen is one of the cleanest-burning fuels known, but storing and transporting it can be a problem - as anyone whos seen footage of the Hindenburg disaster knows. But researchers at Germanys University of Rostock say theyve come up with a solution that could make hydrogen fuel safe and practical, by storing it as liquid methanol.. Not that this hasnt been proposed before. Its easy enough to make methanol from hydrogen; all you need is some carbon and a little oxygen, and any of a number of chemical processes will get you there. The trick, however, is getting the hydrogen back out again when you want to burn it.. Hydrogen fuel cells are twice as efficient as fuel cells that burn methanol, but extracting hydrogen from methanol has meant heating the methanol to 200° C at high pressure - which is hardly practical, given that the goal is to burn hydrogen as fuel, not to burn fuel to extract the hydrogen.. But Matthias Beller and his team at the University of Rostock say theyve figured out a ...
There are potent synergistic effects to the combination of all three products. In particular, using both hydrogen negative ions (H-) or hydride and molecular hydrogen (H2) creates cascade effects in which hydrogen ions "recycle" themselves as antioxidants. The addition of pH Adjust brings its own set of benefits.. • MEGAHYDRATE provides hydride or hydrogen negative ions (H-), also known as anions, that act significantly as antioxidants. These hydrogen ions can last up to three weeks in water. In the body, after the H- has donated its electron, it becomes simply "H" and proceeds to pair with another hydrogen atom to form H2 (molecular hydrogen), thereby continuing to exert free-radical quenching action. This is a major benefit of consuming H- in the quantities provided by Megahydrate.. • ACTIVE H2 ULTRA provides molecular hydrogen (H2) directly into the body in significant amounts. Molecular hydrogen offers many benefits to the body, especially antioxidant benefits. Being an extremely small ...
Streamers of hydrogen gas from outer space are thought to be the source of aurora borealis (the "northern lights") according to a theory advanced yesterday by a University scientist. Donald H. Menzel, professor of Astrophysics and Associate Director for Solar Research in the Harvard Observatory, based his theory on recent discoveries of the University of Colorado high altitude observatory that the sun shoots out streamers of almost pure hydrogen gas, through which the earth continually plows. When the gas breaks through the earths magnetic field, the physicist said, the hydrogen particle become luminescent upon contact with the atmosphere some 200 miles above the earths surface. Menzel, now a visitor at the Colorado observatory at Boulder, believes the energy and heat thrown off by the hydrogen atoms could have important effects on both weather and radio reception.. ...
We present a study of the high-order harmonic-generation (HG) spectra of atomic hydrogen at 248 nm based on the Fourier transform of the expectation values of the induced dipole moment and acceleration. The calculations were performed by extending a fast-Fourier-transformation split-operator technique (in spherical coordinates) to the solution of the time-dependent wave functions in intense laser fields. It is seen that the acceleration form provides a more satisfactory and accurate framework for the study of the photoemission HG spectrum at very intense fields, particularly when ionization becomes appreciable ...
Hydrogen as a next generation energy carrier, is a clear and zero emission fuel with growing application in various fields. Intermodal transportation is an important issue for the safety and economic use of hydrogen fuel in distributed sites. Hydrogen is usually transported in high-pressure cylinders on trucks with bounded space. In this paper, we investigated different cylinder designs, packing strategies and their impact on the storage density, which is defined as the weight of hydrogen divided by the storage space, and then found out the optimal design and packing strategy. The high-pressure hydrogen gas was considered as real gas, and the stress distribution was analyzed for the 4130 steel cylinders based on the thick-wall cylinder model. Two different head designs of sphere and elliptical head were considered and discussed. A high storage density strategy with cylinder geometric parameter design, hydrogen gas pressure and cylinder packing methods were proposed. An exploration of the carbon ...
The effect of different electron acceptors on substrate degradation was studied in pure and mixed cultures of various hydrogenotrophic homoacetogenic, methanogenic, sulfate-reducing, fumarate-reducing and nitrate-ammonifying bacteria. Two different species of these bacteria which during organic substrate degradation produce and consume hydrogen, were cocultured on a substrate which was utilized only by one of them. Hydrogen, which was excreted as intermediate by the first strain (and reoxidized in pure culture), could, depending on the hydrogen acceptor present, also be used by the second organism, resulting in interspecies hydrogen transfer. The efficiency of H2 transfer was similar when methanol, lactate or fructose were used as organic substrate, although the free energy changes of fermentative H2 formation of these substrates are considerably different. In coculture experiments nitrate or fumarate,sulfate, CO2/CH4,sulfur or CO2/acetate were the preferred electron acceptors, and an increasing ...
In a ball mill, a rotating cylinder filled with metal balls will pulverise everything we throw in it!. In the same way, a turbulent mass of water will impact water molecules against everything in the column of water.. If we just have water in turbulent flow, we will get hydrogen on oxygen events, and more importantly hydrogen on hydrogen events.. If we have enough turbulence, we overcome the strong atomic force, and the atoms fuse, to form Helium, with a massive release of heat, and some gamma and light rays.. On suns the boiling mass of gas in turbulent flow does atomic nuclear fusion. On Earth, in the deep seas we do the much meeker Molecular Nuclear Fusion and we see the release of He, O and gamma waves.. Green crops in the light do Molecular Nuclear Fusion, and we see ozone and \he, plus a whiff of CH4. The ozone comes from O bonding with O2. This also happens at water falls and at breaking waves, where we have water in high kinetic interactions.. Steam, IC and jet engines all do vary ...

In the present thesis a study of the mechanisms of hydrogen control pickup during ladle treatment was undertaken. Previous studies showed that the presence of hydroxyl ions in the ladle slag resulteds in hydrogen transfer from the slag back into the steel bath. The main focus of the present work was therefore to gain deeper knowledge of the ladle slag, its properties and impact on hydrogen concentration in the liquid steel. For this purpose a number of slag compositions were examined in order to clarify whether these slags were single liquids at 1858 K. 14 out of 27 compositions in the Al2O3-CaO-MgO-SiO2 system werewas completely melted, while the rest had solid shape present . These results were in disagreement with the existing phase diagram.. Water solubility measurements were carried out by employing a thermo gravimetric technique.

Hydrogen has been reported to relieve damage in many disease models, and is a potential additive in drinking water to provide protective effects for patients as several clinical studies revealed. However, the absence of a dose-response relationship in the application of hydrogen is puzzling. We attempted to identify the dose-response relationship of hydrogen in alkaline electrolyzed drinking water through the aspirin induced gastric injury model. In this study, hydrogen-rich alkaline water was obtained by adding H2 to electrolyzed water at one atmosphere pressure. After 2 weeks of drinking, we detected the gastric mucosal damage together with MPO, MDA and 8-OHdG in rat aspirin induced gastric injury model. Hydrogen-dose dependent inhibition was observed in stomach mucosal. Under pH 8.5, 0.07, 0.22 and 0.84 ppm hydrogen exhibited a high correlation with inhibitory effects showed by erosion area, MPO activity and MDA content in the stomach. Gastric histology also demonstrated the inhibition of damage by

While multiple studies on alloy 718 under conditions of hydrogen embrittlement exist, a complete understanding of the influence of microstructural particularities of alloy 718 has not been reached to date. To address this, a large research program dealing with the effect of precipitates on hydrogen diffusion, hydrogen trapping and decohesion was conducted.. This paper focuses on the effect of heat treatment and microstructure on the susceptibility of alloy 718 to hydrogen embrittlement. Using in-situ tensile testing under electrochemical hydrogen charging, it was found that the ageing temperature clearly has an effect on the susceptibility to hydrogen embrittlement. This can be explained by microstructural features. Several mechanisms including hydrogen-enhanced localised plasticity (HELP) have been identified contributing to the hydrogen embrittlement susceptibility of alloy 718.. A correlation between hardness on the resistance of alloy 718 to hydrogen embrittlement and SSC was not ...
A NiS/C3N4 photocatalyst containing earth-abundant elements only was constructed by means of a simple hydrothermal method. This photocatalyst shows efficient hydrogen evolution (48.2 μmol h−1) under visible light when using triethanolamine as a sacrificial reagent. The optimal loading of 1.1 wt % NiS on C3N4 as a cocatalyst can enhance the H2 production by about 250 times compared with the native C3N4. The highest apparent quantum efficiency of 1.9 % was recorded at 440 nm. ...
So how exactly does a hydrogen car work? The fuel cell on board turns the hydrogen into electricity. The electricity drives the motor and thus the car.

Understanding the mechanisms of resonance photoproduction is essential for both fundamental and practical reasons. On the one hand the structure of resonances is directly related to basic properties of QCD like the confinement. On the other hand reliable models are badly needed to describe the wealth of the resonance photoproduction data to be expected in near future from JLab, ELSA, MAMI, and SPring-8 experiments. Of particular interest is the photoproduction of $\pi^+\pi^-$ pairs on the proton as for a time being this is the only reaction where the photoproduction of scalar $f_0$ resonances has been observed.. We propose a uniform approach which enabled us to simultaneously describe the photoproduction of resonances in low partial waves $S$, $P$ and $D$ [1]. In our approach the photoproduction amplitude consists of two modes, the long range mode - dominated by one pion exchange and the short range mode which collectively includes contributions related to singularities located far away from the ...
The present invention relates to a method of producing hydrogen gas and carbon dioxide in a catalytic reaction from formic acid, said reaction being conducted in an aqueous solution over a wide temperature range and already at room temperature (25 DEG C). The reaction is advantageous because it can be tuned to take place at very high rates, up to about 90 litre H2 / minute / litre reactor volume. The gas produced is free of carbon monoxide. The method of the present invention is particularly suitable for providing hydrogen for a motor, fuel cell or chemical synthesis. Laurenczy, Gabor; Fellay, Celine; Dyson, Paul

At STP, a mole of hydrogen gas would take up 22.4 L. If that hydrogen gas was ionized and stripped of 100% of the electrons, would the remaining protons have a larger volume than 22.4 L? Im not sure because on one hand, taking away the electrons leaves each proton with much less volume, but on the other hand, protons repel from one another ...
Producing Pure Hydrogen - A major problem facing fuel cell technology is that the hydrogen-rich materials feeding the reaction often contain carbon monoxide (CO), which deteriorates the expensive platinum-based catalysts that convert hydrogen into electricity. Brookhavens ultimate goal is to find the catalysts that will help convert nearly 100 percent of the CO into carbon dioxide, an important step toward achieving a hydrogen-based economy.
Hydrogen is the most abundant gas in the universe. It is very small, and it is the first element on the periodic table. Hydrogen is often recognized from two things: H20 and the fact it goes boom when ignited. What a lot of people do not know is that H2 on its own is very…
Dave: Your wrong, or uninformed on both points!. First, we DO have a viable method CURRENTLY and we have had it for atleast a couple years now to store large quantities of hydrogen in a SAFE and effective mannor. Its an alloy of some kind that will store a large volume of hydrogen gas, in a solid form -- No compression needed! Bet most of the people reading this have heard of it! There are a few other ways, but Im tired and dont remember them all! There are currently 2 or 3 ways to store hydrogen on board a vehicle in a safe and productive mannor!. As far as your battery exchange ideas go, thats not likley to happen! First you can charge your OWN batteries in as little as 10 minutes, if your on a long trip your most likley going to spend atleast 10 minutes, going to the bathroom, streching your leggs, and buying another pot or two for coffee. The more you drive in rush hour, the longer that is likley to take (getting the coffee, not the batteries). Second, a battery exchange is also bad for ...

Fatty acids - carbon atoms have four bonds to play with. Each carbon atom in the chain is attached to the two carbon atoms sitting next to it (which takes up two of the available four bonds) and the other two bonds grab onto hydrogen atoms. In the fatty acid on the left every carbon atom has its maximum number of hydrogen atoms attached (two per each Carbon atom, so its said to be saturated with hydrogen, cant take any more) and on the right two carbon atoms have formed a double bond between them. This means that the carbon atoms participating in the double bond have one bond attached singly to another carbon, but two bonds attached (hence double bond) to the other carbon leaving only one bond free to grab a hydrogen atom. This means that the carbon chain is unsaturated with respect to hydrogen, it also means that the molecule isnt balanced - it doesnt have an equal number of hydrogens on both sides. This makes the uneven electrostatic charge try and balance out by repelling and you end ...
Hydrogen gas has long been proposed as a promising energy carrier for future energy applications, but generating the gas from water has proved inefficient. Researchers at Uppsala University have now managed to activate a key enzyme called hydrogenase in E. coli bacteria, which opens the door to future applications in photosynthesising microorganisms.

Researchers Detail New Approach for Finding Catalysts to Improve Hydrogen Production and Storage and Carbon Dioxide Reduction Efforts
Renewable hydrogen could potentially form a cornerstone of Denmarks ambition to reduce greenhouse gas emissions by 70% in 2030 and of the transition to a world that runs entirely on green energy. Heavy road transport is one of the sectors which can be made greener by indirect electrification with hydrogen produced from renewable sources. However, renewable hydrogen is currently more expensive than hydrogen produced from gas or coal. Therefore, its important for us to be able to demonstrate the technology and gather experience, that will make it possible to scale up the technology and make it more efficient, so that well be able to produce renewable hydrogen at a price which can compete with the price of the fossil-based alternatives. ...

In general, the active sites of both classes of hydrogenases contain one free coordination position, which is most likely the catalytically relevant coordination position.[2] For the [NiFe] hydrogenases, which display a rich redox structure in which the nickel atom switches back and forth between the 3+ and 2+ redox state and the iron is 2+, low spin, a hydride ligand has been detected using HYSCORE spectroscopy,[4] which is direct evidence that the catalytic activity indeed occurs at the free coordination position of nickel. Presently, research emphasizes on improving the issue of oxygen sensitivity. In this respect the hydrogenases from extremophile organisms are promising candidates, since these enzymes are much more robust, oxygen insensitive and even function at elevated temperatures.. In a broader sense, besides the H-H bond, Nature often stores energy in chemical bonds of reduced molecules. Well known examples are, e.g., nicotinamide adenine dinucleotide (NADH) or Nicotinamide adenine ...
This means, for example, that a hydrogen-ion concentration of a solution with a pH of 4 is 10-4mol/l, meaning it contains 0.0001 mol of hydrogen ions in a solution of 1 liter. In the same way, a solution with a pH of 5 contains 10-5mol/l of hydrogen ions, a solution with a pH of 6 contains 10-6mol/l of hydrogen ions, while the solution with a pH of 7 contains 10-7mol/l of hydrogen ions. You will notice that if you compare solutions with pH of 4 and pH of 7, the difference in pH is only 3, but the concentration of hydrogen ions with a pH of 7 is 1000 times as high as with a pH of 4.The following figure also shows the advantage of exponents, which can express large variations in value that range over many orders of magnitude.. ...

I am a student of physics and engineering and there is no element I fear more than Hydrogen not even any of the radioactive ones. I would not enter a hydrogen powered vehicle no matter how much I would be paid to do so. In case of a minor malfunction, especially when the hydrogen is stored in liquid form, there will be a BOOM and it will be BIG. There are several scenarios that this could happen. While car manifacturers like Toyota argue that the hydrogen will escape in the atmosphere quick enough that there will not be any fire or explosion that is only a best case scenario. As during a crash that would breach the hydrogen tank, a lot of power will be set free through instant friction heat, that would totally be enough to directly inflame all hydrogen in the tank causing an explosion. The explosion strenght will depend on how much hydrogen is stored in the pressurised container and would be at a stength of 150 kilos of TNT at 5 kilos of liquid hydrogen. Imagine 150 kilos of TNT going off ...

To explain the formation of spectral lines, we must understand not just the nature of light but also something of the structure of atoms-the microscopic building blocks from which all matter is constructed. Let us start with the simplest atom, hydrogen, which consists of an electron, with a negative electrical charge, orbiting a proton, which carries a positive charge. The proton forms the central nucleus (plural: nuclei) of the atom. Because the positive charge on the proton exactly cancels the negative charge on the electron, the hydrogen atom as a whole is electrically neutral.. How does this picture of the hydrogen atom relate to the characteristic emission and absorption lines associated with hydrogen gas? If an atom absorbs some energy in the form of radiation, that energy must cause some internal change. And if the atom emits energy, it must come from somewhere within the atom. The energy absorbed or emitted by the atom is associated with changes in the motion of the orbiting ...
