Adsorption of phenol and chlorophenols on pure and modified sepiolite [PDF]

Journal of the Serbian Chemical Society, 2007
In this work, pure sepiolite and sepiolite modified by nitric acid (HNO3), ethylenediaminetetraacetic acid (EDTA) and hexadecyltrimethylammonium (HDTMA) were used ad adsorbents. The changes on the surface were studied by IR spectroscopy.

Effect of stabilizer EDTA on the thermal hazard of green synthesis process of adipic acid and development of microchannel continuous flow process

Emergency Management Science and Technology, 2023
In the green synthesis reaction of adipic acid, the oxidant H2O2 undergoes exothermic decomposition easily and the high exothermic amount of the reaction can easily lead to thermal runaway.

Structural and biochemical analysis of a B12 superbinder

FEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Comparative evaluation of depth of penetration of sealer after using EDTA, citric acid and R-EDTA as last irrigant under confocal laser microscopy

Endodontology
Aim: This original research examines potential of root canal sealers to penetrate the dentin. Movement of root canal sealer into dentinal tubules decreases the residual space for the entombing of bacteria and provides the hermetic seal.
