Sep-Pak Amino Propyl (NH2) Plus Light cartridges contain a moderately polar, silica-based bonded phase with weakly basic surface. The sorbent can be used as a polar sorbent with different selectivity for acidic/basic analytes or as a weak anion exchanges in ...
To define the TnT core structure and investigate the regulatory role of the NH2-terminal variable region, we investigated two classes of model TnT molecules: (1) NH2-terminal truncated cardiac TnT and (2) chimera proteins consisting of an acidic or basic skeletal muscle TnT NH2-terminus spliced...
Evacuation at 473K leads to a strong (and reversible) decrease in the population of the structural OH groups in UiO-66 and creation of a fraction of more acidic hydroxyls (ΔtνOH=108cm1). Similar results were obtained with the DMF-free UiO-66-NH2: the ΔtνOH was 91 cm1 for a ...
This is unanimous with previous works in which FA was identified as a precursor to form formate esters rather than as an acidic catalyst to accelerate the hydrogenolysis of 5-hydroxymethylfural to 2,5-dimethylfuran at relatively high temperature (>120°C).32, 33, 34 Thus, two possible ...
In this study, a porous nanocontainer from UiO-66-NH2/CNTs nanocomposite with an excellent barrier characteristics was constructed through amine-functionalized Zr-based metal organic framework. The characterization of the prepared nano-materials were per

Studies in the literature have analyzed the effect of basic drugs, such as caffeine [44], on PLA degradation. They have concluded that basic drugs neutralize the carboxyl end groups and minimize the autocatalytic effect of acidic chain ends in polymer degradation and, therefore, the drug release...
