The solid complexes further obtained from these aqueous HCl systems, were investigated by infrared spectroscopy. It was verified that chitosan coordinated with the cations Cu2+, Mn2+ and Zn2+ at pHs ...

2016b). Among these products, chitosan (CHI) and technical cashew nut shell liquid (CNSLt) have been investigated for antimicrobial properties (Pedro et al., 2020; Konda et al., 2019). Chitosan and ...

Chitosan-functionalization is one of several surface functionalization procedures ... To study the surface functional group of the synthesized polymer, X-ray photoelectron spectroscopy (XPS) together ...

Thus, the treatment of burn wounds is a major clinical challenge. Chitooligosaccharides (COS) are alkaline amino oligosaccharides with small molecular weights obtained by enzyme or chemical ...

Here, we show the combination of GO and chitosan (CTS) into inorganic–organic heterocomposites as ∼3 mm diameter ... SEM characterization of reversed bead structure; beads prepared from CTS with ...

Thus, a novel fault diagnosis method based on spectrum transition entropy (SpTE) is proposed. First, a symbolization method is constructed to represent the time-frequency distribution (TFD) of signals ...

Picometric spectroscopy of hydrogen molecules in atomic-scale cavities Date: May 21, 2025 Source: Fritz Haber Institute of the Max Planck Society Summary: Researchers have observed hydrogen and ...

These included ongoing deregulatory efforts, workforce changes and a push to restore congressional spectrum authority. Carr touted the FCC’s “Delete, Delete, Delete” initiative, aimed at eliminating ...
