Summary: This study reports the optimised synthesis of N-carboxymethylated chitosan (CM-Cts) and its crosslinking with glutaraldehyde to obtain CM-Cts-Glu as a metal ion sorbent. CM-Cts-Glu showed better metal ion uptake properties compared to crosslinked chitosan (Cts-Glu), and the sorption-desorption kinetics indicated the feasibility of reusing CM-Cts-Glu without any loss in capacity. The maximum Co(II) uptake obtained for CM-Cts-Glu was 265 μmol/g, while for Cts-Glu it was 10 μmol/g. The metal ion sorption by CM-Cts-Glu was through chelation by the carboxylic acid functional groups present over the chitosan backbone. The study also confirmed the utility of CM-Cts-Glu in complexing decontamination formulations used in the nuclear industry.

Summary: The surface of exfoliated 2H-MoS2 was activated by reacting with NaBH4, forming an n-doped material with similar spectral properties to pristine 2H-MoS2. The activated material could be dispersed in water, unlike the untreated 2H-MoS2. Its dispersibility was correlated with the relative permittivity of the solvents used. This approach enables the aqueous dispersion of semiconducting 2H-MoS2 without additives, and allows for controlled and facile functionalization, opening new possibilities for MoS2 applications.

Summary: This study focuses on the research of new sorption materials based on silica-doped activated carbon. A two-stage synthesis process was used, involving the pyrolysis of plant material impregnated in a water glass solution, followed by hydrothermal activation in KOH solution. The resulting composite showed potential as a sorbent in drinking water filters. The research confirmed the material's surface area, chemical composition, and structure through various analysis methods. The optimal operating parameters for the sorption of copper ions were determined, as well as the sorption kinetics and isotherm models. The maximum sorption capacity of copper ions was found to be 37.74 m.g(-1), indicating the potential use of the material in drinking water filters.

Summary: In this study, highly crystalline layered SnSe nanoribbons were grown using a simple solution-phase approach. The use of PVP as a templating agent allowed for selective passivation of certain facets, resulting in unique growth of nanoribbons along their b-axis with a defined zigzag edge state. The SnSe nanoribbons exhibited few layers, wide widths, and achievable lengths, with the ability to produce them in high quantities in a single batch experiment. The use of non-toxic PVP as a replacement for toxic amines in other forms of SnSe is an important advantage for sustainable and environmentally friendly applications. The heat transport properties of the SnSe nanoribbons, determined through power-dependent Raman spectroscopy, demonstrate their potential as thermoelectric materials.

Summary: FeSiB based soft magnetic flakes coated with optimally thick SiO2 were produced by mechanical ball milling and optimized sol-gel coating. The milling process reduced ribbon thickness to minimize eddy current loss, and a tiny fraction of the flakes were allowed to become nanocrystalline, enhancing saturation flux density and permeability without incurring additional losses. A stress-releasing post-annealing process further improved the magnetic properties without affecting the insulating SiO2 layer.

Summary: Melt-spun Fe-based ribbons are commonly used in transformers and inductors due to their high flux density and low coercivity. However, their high thickness results in significant eddy current losses at MHz frequencies. This study demonstrates an optimized ball milling process to produce high-yield flakes in the desired size range (2-4 μm) to suppress the eddy current losses. The findings provide an efficient approach to fabricate ultra-thin flakes for high-frequency applications.

Summary: In this study, we demonstrated the formation of oxide porous and nanodot structures from the same block copolymer (BCP) through the phase inversion of a BCP template. The effect of solvent annealing time on the ordering of the BCP was investigated. Metal ions were infiltrated into the BCP templates and oxidized to their oxides. The resulting structures were analyzed through various methods, confirming the complete elimination of the BCP template and the presence of metal oxides.

This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.
