It has been shown that the enzymic addition of valine to valine transfer ribonucleic acid (tRNA) of Escherichia co2i is exceedingly sensitive to alcohol or salt concentrations and that the rate of the reaction is predictable from the Debye-Htickel equations, if it is assumed that there are somewhat more than 4 positive charges and 4 negative charges involved in the rate-determining step. (For i...

Salt metathesis and BFX (boron–fluoride exchange) of BF4− with boronic acids generates RBF3− derivatives, thus showing the solvolytic lability that enables its use as a fluorinating agent, even though many highly reactive reagents employ non-reactive counteranion. In their Research Article (e202215371), David M. Perrin co-workers report synthesis derivatives via salt reaction using series MBF4 ...

Bamboo salt, a Korean folk medicine, is prepared with solar salt (sea salt) and baked several times at high temperatures in a bamboo case. In this study, we compared the preventive effects of bamboo salt and purified and solar salts on hepatic damage induced by carbon tetrachloride in Sprague-Dawley rats. Compared with purified and solar salts, bamboo salts prevented hepatic damage in rats, as ...

Nanosilica periodic acid (nano-SPIA) is found to be a new, powerful, and reusable heterogeneous catalyst for the rapid synthesis of 2-naphtholazo dyes via diazotization of aromatic amines and followsazo coupling with 2-naphthol under solvent-free conditions at room temperature by grinding. Eco-friendly, heterogeneous reaction conditions, high stability of diazonium salt, simple experimental pro...

In this research the  ion exchange potential of natrolite towards K+, Tl+, Cs+, Ca+2, Ni+2, Cu2+, and Co2+ in their melted salts was investigated. The effect of temperature, reaction time and zeolite to salt ratio on the exchange relation was studied. The exchange of Ca2+, Ni2+, Cu2+, and Co2+ was negligible and was equal to 2.59, 6.29, 3.14 and 5.04 percent respectively whereas the exchange of...
