The response time of thermal electrolytic Ag/AgCl reference electrodes is defined by the porous structure that limits the rate at which traces of any previous solution are diluted by any new solution environment. The electrode stabilisation time when transferred from one electrolyte to another has been shown to change when different structural designs to the conventional sphere of Ag/AgCl are used. Electrodes fabricated with cylindrical architectures of Ag/AgCl have shown improved stability and reach equilibrium faster than spherical electrodes. This work has positive implications for the accuracy and throughput of primary pH measurements made using the Harned cell.

Title: Antibacterial Behaviour of Cu2O Nanoparticles Against Escherichia coli; Reactivity of Fehlings Solution on Manihot esculenta Leaf Extract. VOLUME: 7 ISSUE: 5. Author(s):C. Ramesh, M. HariPrasad and V. Ragunathan. Affiliation:Department of Chemistry, Kandaswami Kandars College, P.Vellur, Tamilnadu, India.. Keywords:Cu2O nanoparticles, Escherichia coli, Fehlings solution, Manihot esculenta, Antibacterial Behaviour. Abstract: We report a simple, low cost and eco-friendly synthesis of Cu2O nanoparticles by reduction of Fehlings solution using Manihot esculenta leaf extract containing reducing sugars which act as reducing agent. The purification process of the Cu2O product does not require expensive methods, since a solid product is obtained from a reaction in liquid phase. The result indicates that aldehyde group present in reducing sugars plays excellent role in the formation of cuprous oxide nanoparticles in the solution. The antibacterial properties of Cu2O nanoparticles were ...

Kinetic studies for the non-isothermal decomposition of unirradiated and γ‑irradiated silver acetate with 103 kGy total γ-ray doses were carried out in air. The results showed that the decomposition proceeds in one major step in the temperature range of (180-270 °C) with the formation of Ag2O as solid residue. The non-isothermal data for un‑irradiated and γ-irradiated silver acetate were analyzed using Flynn-Wall-Ozawa (FWO) and nonlinear Vyazovkin (VYZ) iso-conversional methods. These free models on the investigated data showed a systematic dependence of Ea on a indicating a simple decomposition process. No significant changes in the thermal decomposition behavior of silver acetate were recorded as a result of γ-irradiation. Calcinations of γ-irradiated silver acetate (CH3COOAg) at 200 °C for 2 hours only led to the formation of pure Ag2O mono-dispersed nanoparticles. X-ray diffraction, FTIR and SEM techniques were employed for characterization of the synthesized nanoparticles.

BACKGROUND: Silver acetate produces an unpleasant taste when combined with cigarettes, thereby producing an aversive stimulus. It has been marketed in various forms with the aim of extinguishing the urge to smoke, by pairing the urge with an unpleasant stimulus. OBJECTIVES: The aim of this review was to determine the effectiveness of silver acetate products (gum, lozenge, spray) in promoting smoking cessation. SEARCH STRATEGY: We searched the Cochrane Tobacco Addiction Group trials register. SELECTION CRITERIA: We included randomised trials of silver acetate for smoking cessation with reports of smoking status at least six months after the beginning of treatment. DATA COLLECTION AND ANALYSIS: We extracted data in duplicate on the type of subjects, the dose and form of silver acetate, the outcome measures, method of randomisation, and completeness of follow-up. The main outcome measure was biochemically validated abstinence from smoking after at least six months follow-up in patients smoking at baseline.

Johann W. Ritter, it was discovered in 1801 when he was experimenting with silver chloride, a chemical which turned black when exposed to sunlight. He had heard that exposure to blue light caused a greater reaction in silver chloride than exposure to red light. Ritter decided to measure the rate at which silver chloride reacted when exposed to the different colors of light. To do this, he directed sunlight through a glass prism to create a spectrum. He then placed silver chloride in each color of the spectrum. Ritter noticed that the silver chloride showed little change in the red part of the spectrum, but increasingly darkened toward the violet end of the spectrum. This proved that exposure to blue light did cause silver chloride to turn black much more efficiently than exposure to red light ...

Tensides or surfactants are amphiphilic organic compounds that consist of both hydrophobic and hydrophilic parts. Tenzides are used in food industry (bakery), pharmaceutical industry, chemical industry, etc. Amylose is an essential unbranched form of starch. It is composed of glucose units which are linked with α-1,4- glucosidic bounds creating a spiral chain in shape of a helix. Potentiometric titration of amylose (0; 0.1; 0.5; 1; 2 and 4%) with octadecyl-trimethyl ammonium bromide (4 x 10-3 moldm-3) was followed by the formation of inclusion complex by changing the critical micellar concentration. In amylose OTAB complex formation mechanism fatty hydrocarbon chain cationic surfactants OTAB enters the amylose helix. The electrodes that were used during the experiment were silver/silver chloride (Metrohm) as the reference electrode and surfactant-sensitive electrodes with plasticized PVC membrane ...

00 if they were sure that they would receive an electrical stimulation, and near 50 if they were unsure. Responses were recorded throughout the experiment and sampled at 40 Hz. We then averaged the values across the last four seconds of the stimulus period for each trial. These Baicalein 6-methyl ether side effects averages were then used in subsequent group level analysis.Skin conductance responsesWe recorded skin conductance level (SCL) via two surface cup electrodes (silver/silver chloride, 8 mm diameter, Biopac model EL258-RT, Goleta, CA) filled with electrolyte gel (Signa Gel, Parker laboratories Fairfield, NJ) attached to the bottom of the participants left foot approximately 2 cm apart. SCL was sampled at 200 Hz throughout the experiment. We identified the peak SCL value during the 8-s trial and expressed it as a percent change from the average of the preceding 2-s baseline (Balderston and Helmstetter, 2010; Balderston et al., 2011). These values were used in subsequent group level ...

Equations were developed for the calculation of the second stoichiometric (molality scale) dissociation constants (Km2) of a-alanine, valine, and leucine in aq. KCl solutions at 298.15 K from the revised thermodynamic dissociation constants (Ka2) of these acids and the ionic strength (Im) of the solutions. The ionic strength of the solutions considered in this study is determined mostly by KCl alone, and the equations for Km2 were based on the single-ion activity coefficient equations of the H�ckel type. The existing literature data obtained from Harned cell measurements and new potentiometric titration data were used to revise the Ka2 values of the three amino acids. The values (1.295 � 0.013) � 10�10, (1.894 � 0.009) � 10�10, and (1.685 � 0.011) � 10�10 were obtained from the new potentiometric titration data for a-alanine, valine, and leucine, respectively. For alanine and valine, the new Ka2 values are also supported by the Harned cell data ...

All electromyographic (EMG) data were collected using an electrode configuration for use with pre- amplified bipolar, grounded, surface electrodes (Mega Electronics Ltd., MESPEC 4000 system amplifiers, Finland). Muscles were targeted bilaterally on the URA (2.5 cm above the umbilicus), LRA (2.5 cm below the umbilicus), EO (1.0 cm medial to the anterior superior iliac spine, 0.5 cm superior to the inguinal ligament) and lumbar paraspinal (PS) muscles using 10 mm bipolar, surface silver- silver chloride electrodes (1700 CLEARTRACETM, Conmed Corporation, Utica, NY). The electrodes were oriented parallel to the muscle fibers with an inter-electrode distance of approximately 40 mm. At each electrode site, the surface silver-silver chloride ground electrode was 10 mm in diameter. Prior to the application of the self-adhesive electrodes, the skin over each muscle was shaved with a disposable razor and cleansed with alcohol prep pads (70% Isopropyl Alcohol) to reduce impedance at the skin electrode ...

Recommended for cavity filling. The design and the structural integrity of the dressing allow you to cut the dressing and make it fit to wounds of many sizes, shapes and depths. The dressing will conform to the wound bed, which is important for the wound healing process.. High dressing integrity. The high dressing integrity allows for one-piece removal of the dressing with minimal pain and trauma (1,2).. Minimized risk of leakage and maceration. The superior absorption of Biatain® Alginate (1,2) and the gel formation, which locks the exudate inside the dressing, prevent leakage that can damage the periwound skin.. Documented hemostatic effect. Contrary to hydrofibre dressings, Biatain® Alginate has documented hemostatic effect, i.e. the ability to arrest blood flow in minor bleedings due to the release of calcium ions from the dressing (4,5)..

Nanoparticles of Ni{sub 1−x}Zn{sub x}O and Ni{sub 1−x}Zn{sub x}O/ZnO, which can be good candidates for selective gas sensors, were successfully obtained via a two-step synthetic route, in which the nickel zinc malonate precursor was first synthesized by co-precipitation from an aqueous solution, followed by pyrolysis in air at a relatively low temperature (~500 °C). The precursor was characterized by ICP-AES, FTIR and TG and the results indicate the molecular structure of the precursor to be compatible with Ni{sub 1−x}Zn{sub x}(OOCCH{sub 2}COO)·2H{sub 2}O. The decomposition product, characterized using various techniques (FTIR, XRD, ToF-SIMS, SEM, TEM and XPS), was established to be a doped nickel oxide (Ni{sub 1−x}Zn{sub x}O for 0.01≤x≤0.1) and a composite material (Ni{sub 1−x}Zn{sub x}O/ZnO for 0.2≤x≤0.5). To elucidate the form in which the Zn is present in the NiO structure, three analytical techniques were employed: ToF-SIMS, XRD and XPS. While ToF SIMS provided a direct ...

It was concluded that, while a negative result in an in vitro cytotoxicity study is very reassuring, a positive result in this artificial test system is not necessarily indicative of a risk in actual use. Cytotoxicity potential was found to be of particular concern in regard to new cell growth (healing). If the healing process is unaffected by a treatment, then the observation of cytotoxicity in a highly sensitive 10993-5 test was considered to be of little or no practical consequence. In the wound healing study, no significant local reactions or impairment of wound healing was identified, compared to a suitable control. Overall, therefore, bibra was able to conclude that the silver-containing wound dressing was biocompatible, with respect to this endpoint. ...

In order to dissolve a salt, you have to break apart the ions and hydrate them in solution. You can use the enthalpies of hydration of the ions, and the crystal lattice energy of the solid, to predict which compounds will dissolve.. I found data that the crystal lattice energy of $\ce{AgCl}$ is -916.3 kJ/mol (experimental), while the lattice energy of $\ce{AgNO_3}$ is -820 kJ/mol. (Since lattice energy is defined as the energy released when the ions join to form a solid, it is always negative. Reverse the sign for the amount of energy you need to put in to break the crystal apart into separate ions in the gas phase.) From this data you can see that it takes quite a bit more energy to break apart the $\ce{Ag+}$ and $\ce{Cl-}$ ions than it does the $\ce{Ag+}$ and $\ce{NO3-}$ ions, presumably because the chloride ion is smaller and more tightly held. If the enthalpy of hydration value is about the same for the two cases (I couldnt find actual values), then it may not be enough to overcome the ...
