Abstract. Parallel microscale experimentation was used to develop general conditions for the Suzuki-Miyaura cross-coupling of diversely functionalized primary alkyltrifluoroborates with a variety of aryl chlorides. The conditions that were previously identified to promote the cross-coupling of secondary alkyltrifluoroborates with aryl chlorides were not optimal for primary alkyltrifluoroborates.. ...

Treat all of houses wood with a sodium borate Yes, all of the wood should be treated with a sodium borate. What they recommended is fine if all you get is subterranean termites, but there are drywood termites in the area, as well as several species of wood-destroying beetles. Most companies just treat the bottom few feet because all they need is a hand sprayer for that. There are companies that have the necessary equipment to treat all the wood in the house. Either of these will protect the wood for many years from being attacked by any wood-destroying insects, including termites, wood-boring beetles, carpenter ants and carpenter bees. In New Zealand, it has been required since 1954 that all wood used in homes be treated with a sodium borate before installation. Is there an easier and safer way of dealing with these destructive pests? Have your home treated with XT-2000 Orange Oil. With XT-2000, they will use the same amount of product for the beetles, so the cost will be considerably less and
TY - JOUR. T1 - NaBC1 is a ubiquitous electrogenic Na+-coupled borate transporter essential for cellular boron homeostasis and cell growth and proliferation. AU - Park, Meeyoung. AU - Li, Qin. AU - Shcheynikov, Nikolay. AU - Zeng, Weizong. AU - Muallem, Shmuel. PY - 2004/11/5. Y1 - 2004/11/5. N2 - Boron is a vital micronutrient in plants and may be essential for animal growth and development. Whereas the role of boron in the life cycle of plants is well documented, nothing is known about boron homeostasis and function in animal cells. NaBC1, the mammalian homolog of AtBor1, is a borate transporter. In the absence of borate, NaBC1 conducts Na+ and OH- (H+), while in the presence of borate, NaBC1 functions as an electrogenic, voltage-regulated, Na+-coupled B(OH)4 - transporter. At low concentrations, borate activated the MAPK pathway to stimulate cell growth and proliferation, and at high concentrations, it was toxic. Accordingly, overexpression of NaBC1 shifted both effects of borate to the left, ...
What Is Borax? Borax (also known as sodium borate decahydrate; sodium pyroborate; birax; sodium tetraborate decahydrate; sodium biborate) is a natural mineral compound (Na2B4O7 • 10H2O). It was discovered over 4000 years ago. Borax is usually found deep within the ground, although it has been mined near the surface in Death Valley, California since the 1800s. Although it has numerous industrial uses, in the home borax is used as a natural laundry booster, multipurpose cleaner, fungicide, preservative, insecticide, herbicide, disinfectant, dessicant, and ingredient in making slime. Borax crystals are odorless, whitish (can have various color impurities), and alkaline. Borax is not flammable and is not reactive. It can be mixed with most other cleaning agents, including chlorine bleach. How Does Borax Clean? Borax has many chemical properties that contribute to its cleaning power. Borax and other borates clean and bleach by converting some water molecules to hydrogen peroxide (H2O2). T. ...
Sodium borate is used in biochemical and chemical laboratories to make buffer solutions, e.g. for gel electrophoresis of DNA. It has a lower conductivity, produces sharper bands, and can be run at higher speeds than can gels made from TBE Buffer or TAE Buffer (five to 35 V/cm as compared to five to ten V/cm). At a given voltage, the heat generation and thus the gel temperature is much lower than with TBE or TAE buffers, therefore the voltage can be increased to speed up electrophoresis so that a gel run takes only a fraction of the usual time. Downstream applications, such as isolation of DNA from a gel slice or Southern blot analysis, work as expected with sodium borate gels. Borate buffers (usually at pH 8) are also used as preferential equilibration solution in DMP-based crosslinking reactions.. Lithium borate is similar to sodium borate and has all of its advantages, but permits use of even higher voltages due to the lower conductivity of lithium ions as compared to sodium ions.[3] However, ...

The reagent offers low toxicity and a long shelf life. SPB is a useful reagent in organic synthesis as a substitute for the unstable, highly concentrated hydrogen peroxide solutions that can pose a significant explosion hazard and are not commercially available.. Sodium perborate is soluble in water and releases hydrogen peroxide, but it is not merely a mixture of hydrogen peroxide and sodium borate. NMR and Raman spectroscopy indicate that in dilute solution, an equilibrium exists that still contains peroxoborate anions. These peroxoborate species are able to deliver the hydroperoxide anion at a lower pH than when H2O2 is used:. ...

Slime works when you get a substance to bond with the molecules of Borax (sodium borate). Polyvinylacetate (white glue) and other substance mixed with borates create new molecules (polymers). For example white glue molecules are long to begin with, and they are tangled, which is why the glue is so viscous. Once the Borax links up some of the molecules, it becomes even more viscous with a slimy feel. ...

Although boric acid is known to complex with various polyalcohols, it is often used as a component of buffer mixtures. Electrochemical and spectrophotometric experiments have shown that borate buffers exhibit two types of interference with ortho quinone redox systems. Ortho quinones themselves exist in equilibrium with electroinactive complexes in borate solutions. The corresponding hydroquinones formed by reduction of the quinones complex even more strongly giving complexes which may be oxidized back to the quinone, but at a much higher potential than for the hydroquinone.. ...

Although it cited inconclusive data, a re-evaluation in 2006 by the EPA still found that "There were no signs of toxicity observed during the study and no evidence of cytotoxicity to the target organ."[37] In the reevaluation, a study of toxicity due to overexposure was checked and the findings were that "The residential handler inhalation risks due to boric acid and its sodium salts as active ingredients are not a risk concern and do not exceed the level of concern..." but that there could be some risk of irritation to children inhaling it if used as a powder for cleaning rugs.. Sodium tetraborate decahydrate has no known hazard issues.[38][clarification needed]. Conditions defined as "over-exposure" to borax dust can cause respiratory irritation, while no skin irritation is known to exist due to borax. Ingestion may cause gastrointestinal distress including nausea, persistent vomiting, abdominal pain, and diarrhea. Effects on the vascular system and human brain include headaches and lethargy, ...
This thesis centers on reactivity of nitric oxide and several of its congeners such as nitroxyl (HNO), nitrite (NO2-), nitrous oxide (N2O) and nitrogen dioxide (NO2) with biomimetic models of copper and zinc enzymes. In addition, metal-free frustrated Lewis pairs are used to capture and activate NO. Tris(pyrazolyl)borate complexes of copper were employed to examine the coordination and NO reactivity of nitrosobenzene (PhNO), an HNO analogue stable towards irreversible dimerization, that provides insight into how HNO can bind to biologically relevant copper enzymes. Tris(pyrazolyl)borate complexes of zinc were used to model the reactivity of zinc bound nitrite (NO2-) with thiols RS-H that generates S-nitrosothiols RSNO that decompose to NO, outlining a new pathway for NO production from NO2-. Reaction of NO with two coordinate -diketiminato copper complexes was consistent with the production of oxidizing cis-hyponitrite intermediates subject to N2O loss to form copper-oxo species. These ...
69. Just what search in Ryker were appellants forced to make, such that their finding was out-of-the-way, and therefore patentable? Certainly they did not have to search through the 52 aryl alkyl ureas for a particular urea. The search was done for them since the particular "1,3 substituted urea" they used was commercially available as the herbicide CMU or Telvar (used in the affidavit), a product sold by du Pont, Rykers assignee. Appellants acknowledge that, but the thrust of their argument is that sodium borates is buried in a list of 18 classes of compounds, and that borax is even more buried within the class. But, since the class "alkali metal borates" is claimed, we need look only for any member of the class, not the particular member borax. The list of the 18 classes is set out on page 8 of the opinion. It is actually two lists, the asterisks separating the first list of "hormonal type" herbicidal compounds from the remaining list of 14 "contact type" herbicidal compounds. We are ...
TY - JOUR. T1 - A Nuclear Magnetic Resonance Study of Hydrogen Bonding in Tris(2-N-methylaminoethyl) Borate and Similar Compounds. AU - Meek, Devon W.. AU - Springer, Charles S.. PY - 1966/3. Y1 - 1966/3. N2 - Tris(2-aminoethyl) borate, B(OCH2CH2NH2)3, and the analogous N-methylamino and N,N-dimethylamino compounds have been prepared by the transesterification of methyl borate with the appropriate 2-aminoethanol. The nuclear magnetic resonance spectra show that extensive association of the terminal amino groups occurs in pure tris(N-methylaminoethyl) borate and that this association can be broken apart by heating to 160° or by dissolution in polar organic solvents such as triethylamine or acetonitrile. In order to determine whether the association results from hydrogen bonding or internal B-N coordination, several model systems have been investigated. The spectra of NH2C5H5-BF3, piperidine-BF3, and (C6H5)BO-CH2CH2NH2 in acetonitrile contain very complicated NCH2 peaks and broad NH peaks which ...
In this study, nano sized zinc borate powder with a formula of 4ZnO center dot B2O3 center dot H2O was synthesized using 2ZnO center dot 3B(2)O(3)center dot 3.0-3.5H(2)O as a starting chemical which was produced using a wet chemical method. After dissolving 2ZnO center dot 3B(2)O(3)center dot 3.0-3.5H(2)O in an ammonia solution, the clear solution was boiled until a white powder formed. The resultant powder was characterized with XRD, FTIR, TGA and TEM. XRD, FTIR and TGA results proved that the powder was belonged to the 4ZnO center dot B2O3 center dot H2O. Nano composites of 4ZnO center dot B2O3 center dot H2O-polyvinylchloride (PVC) were produced by injection moulding by adding 1 and 5 wt% zinc borate powders into PVC to enhance its flame retardancy. Limiting oxygen index (LOI) of virgin PVC increased from 41% to 47% and 54% for the 1 and 5 wt% zinc borate added PVC, respectively. Nano zinc borate addition into the PVC does not have considerable negative effect on the mechanical properties of ...

Just as anyone who is looking closely at the cleaning products they use around the home is getting used to the name Borax, the EU makes some law that means it will no longer be available on the high street from June. Cleaning gurus often tell us to add borax to our arsenal of natural and traditional cleaning products, along with bicarbonate of soda, white vinegar, lemon juice and soda crystals. A reclassification of the Borates group of minerals means that they are no longer available as a general cleaner. Borax is principally used for cleaning and laundry purposes, but many have also used them to kill ants and weeds for example. Yet all is not lost as Dri-Pak, one of the few suppliers of domestic borax is already supplying a Borax substitute that has all the same cleaning and laundry properties without the potentially hazardous applications ...

TY - JOUR. T1 - Redox potential of Mo(VI)/Mo in alkali borate melts. AU - Nakanishi, Takuya. AU - Maekawa, Hideki. AU - Yokokawa, Toshio. PY - 1998/3. Y1 - 1998/3. N2 - The redox potential of molybdenum oxides in alkali borate melts was studied using the cyclic voltammetry. In the Na 2O-B 2O 3 melts, where the Na 2O activity had been previously measured and the basicity was defined as pO= -log a (Na 2O), the redox potential corresponding to Mo(VI)/Mo shifted to the positive side as the melts became more acidic, linearly depending on the basicity of the solvent melts. We succeeded in quantitatively interpreting this behavior from a thermodynamic viewpoint. In other alkali borate melts, R 2O-B 2O 3 (R=Li, K and Cs), the redox potential shifted to the negative side when alkali was exchanged from lithium and potassium to cesium at the same composition. It is shown that the redox potential of Mo(VI)/Mo can be applicable to determine the basicity in high temperature melts in general.. AB - The redox ...
