STUDIES ON CHITOSAN - BENZALDEHYDE INTERACTION IN A HOMOGENEOUS SYSTEM AND ITS ADSORPTION BEHAVIOR OF METAL IONS IN AQUEOUS SOLUTION

ASEAN Journal on Science and Technology for Development, 2017
In this work, N-benzylidene chitosan was synthesized by chitosan –benzaldehyde interaction in a homogeneous system. The modified polymers were characterized by means of infrared (IR) spectra, X-Ray diffraction and thermal analysis.

Identification and Characterization of an In Silico Designed Membrane‐Active Peptide with Antiviral Properties

Advanced Science, EarlyView.
An evolutionary molecular dynamics platform is used to design P1.6, a membrane‐active peptide that senses lipid packing defects in viral envelopes. P1.6 adopts a stabilized α‐helical structure upon membrane contact, disrupts virus‐like liposomes, and damages HIV‐1 particles.

Photocatalytically Activated Cu‐N1S3 Single‐Atom Nanozyme: Enhancing Enzyme Activities and Antibacterial Synergy for Highly Efficient Fruit Preservation

Advanced Science, EarlyView.
This study presents S‐coordinated Cu single‐atom nanozymes (Cu/CNS) fabricated via mild photocatalytic self‐assembly strategy. The nanozyme exhibits exceptional multi‐enzyme activity and near‐perfect antimicrobial efficacy. Incorporated into chitosan‐gelatin film, it enables pH‐responsive, broad‐spectrum fruit preservation, more than doubling the shelf‐

Milk urea analytical result reliability and its methodical possibilities in the Czech Republic

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2013
Control of milk urea concentration (MUC) can be used in diagnosis of the energy–nitrogen metabolism of cows. There are more analytical methods for MUC estimation and there are also discussions about their result reliability.

An analysis of the shapes of interstellar extinction curves. VII Milky Way spectrophotometric optical-through-ultraviolet extinction and its R-dependence [PDF]

, 2019
We produce a set of 72 NIR-through-UV extinction curves by combining new Hubble Space Telescope/STIS optical spectrophotometry with existing International Ultraviolet Explorer spectrophotometry (yielding gapless coverage from 1150 to 10000 ?) and NIR ...

Mechanisms of Direct Electron Transfer Governed by Redox‐Active Conductive Carrier with Superior Wettability in Anaerobic Biofilms

Advanced Science, EarlyView.
A redox‐active conductive carrier of tannic acid‐modified iron‐biochar with superior wettability is demonstrated to regulate direct electron transfer at the anaerobic biofilm‐carrier interface by enhancing the cytochrome c‐mediated pathway. For the first time, integrated evidence from spectroscopy, electrochemical analyses, and metatranscriptomics ...
