EPR Spectroscopy Investigation of Cu2+ Ions Adsorbed in Tannin-Formaldehyde Resins of Mimosa (Acacia mearnsii) Bark Extracts

Journal of Spectroscopy, 2015
The chemical environment of Cu2+ ions adsorbed in tannin-formaldehyde resins of Acacia mearnsii bark extracts, prepared from polybutene, is investigated by EPR spectroscopy at 300 K. The spectrum is simulated considering two isolated axial Cu(II) species

Overcoming the Nyquist Limit in Molecular Hyperspectral Imaging by Reinforcement Learning

Advanced Intelligent Discovery, EarlyView.
Explorative spectral acquisition guide automatically selects informative spectral bands to optimize downstream tasks, outperforming full‐spectrum acquisition. The selected hyperspectral data are used for tasks such as unmixing and segmentation. BandOptiNet encodes selection states and outputs optimal bands to guide spectral acquisition. Recent advances

Impact of Chitosan Incorporation on PBAT Composite: Thermal, Viscoelastic, Mechanical, and Morphological Properties

Journal of Applied Polymer Science, EarlyView.
The abstract explains the impact of various concentrations of chitosan on PBAT composite. Indeed, the composite is produced at increasing concentrations of chitosan (10%, 20%, and 30%). The decrease in the tensile strength with increased conc. of chitosan was recorded. Furthermore, the same impact was recorded for TGA analysis.

Liquid‐phase oxidation of furfural catalyzed by magnetically separable metal oxide nanoparticles deposited on silica gel

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Oxidation of furfural (FF), a bio‐based platform chemical, was investigated using a range of iron‐, vanadium‐ and iron–zinc‐oxalates supported on silica gel (FeVOx@silica and FeZnOx@silica, respectively) as precursor for FeV@silica and FeZn@silica oxide catalysts and H2O2 as a green oxidant.

Cluster Analysis of Circular Economy and Industrial Symbiosis Practices and Their Impact on Sustainability Performance in the Plastics Industry

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines how plastics manufacturing firms can be classified according to their level of implementation of circular economy (CE) and industrial symbiosis (IS) practices and how such adoption influences sustainability performance. Using data from plastics manufacturing firms, we integrate cluster analysis with partial least squares ...
