Isomorphous Substitution of P(V) in Natural Clinoptilolite: Evalution of the Product for Removal of NO3-, NO2- and F - from Aqueous Solutions [PDF]
Nitrate is an anion of major importance particularly in biological areas. Excessive amounts in water supplies indicate pollution from sewage or agricultural effluents. The effects of excessive quantities of nitrate in water are well known.

Glutamine Phosphoribosylpyrophosphate Amidotransferase-independent Phosphoribosyl Amine Synthesis from Ribose 5-Phosphate and Glutamine or Asparagine [PDF]
Phosphoribosylamine (PRA) is the first intermediate in the common pathway to purines and thiamine and is generated in bacteria by glutamine phosphoribosylpyrophosphate (PRPP) amidotransferase (EC 2.4.2.14) from PRPP and glutamine.

This study proposes a sustainable solution for rainwater‐driven energy harvesting by harnessing the intrinsic properties of lignin in wood. The first demonstration of an all‐wood tribonegative material for liquid–solid triboelectric nanogenerators is presented, eliminating the need for fluorine‐containing polymers and functional additives. Abstract The

The replacement of the anodic OER in CO2RR with energy‐saving methanol oxidation reaction and the creation of a favorable microenvironment through interfacial Cl− ions enable concurrent formate production at industrial‐level current densities. Abstract The efficient electrocatalytic conversion of CO2 to formate is often impeded by the high energy ...

A new method for determination of fluoride ion in commodity tea by ion-exclusion chromatography
Due to the effect of interfering ion, the content of fluoride ion in tea brew, detected by ion-exchange chromatography, was markedly higher than ion-selective electrode.

The Techniques of Thin Layer Chromatography and the Study of Carbohydrates Using Thin Layer Chromatography [PDF]
Refined Kraft pulp is found to contain D (+), Mannose, D (+) Xylose, and Glucose; and not to contain Galactose. Silia gel plates and Kieselguhr plates were used for the separation.

Obtaining and Characteristic of the Autolysate of Lactic Acid Bacteria [PDF]
Fragments of bacterial peptidoglycan relating to compounds of the muropeptide series have high biological activity. They have an immunological effect, due to the fact that they are signals for immune receptors and, accordingly, their activators. In order

Internally catalyzed siloxane dynamic chemistry is demonstrated resulting from amides covalently linked through alkyl chains to siloxanes. The alkyl length in the siloxane‐containing monomer tunes the network cross‐link density. Siloxane exchange dynamics are faster with increasing cross‐link density, because associative exchange is second order in ...
