Crop-Derived Biochar for Removal of Alachlor from Water.

The presence of various pesticides in natural streams and wastewater is a significant environmental issue due to their high toxicity, which causes harmful consequences even at low quantities. One cost-effective method to remove these pollutants from water could be through adsorption using an inexpensive, easily obtained adsorbent-biochar. The presented research demonstrates the efficacy of applying biochar obtained from wheat grains to eliminate alachlor from water.

Poly-Amino-β-Cyclodextrin Microparticles for the Reduction of Xenobiotics and Emerging Contaminants, Including Pharmaceuticals, from the Natural Environment.

The contamination of the natural environment by xenobiotics and emerging contaminants, including pharmaceuticals, poses significant risks to ecosystems and human health. Among these contaminants, hormones and pharmaceutical compounds are particularly concerning due to their persistence and potential biological effects even at low concentrations. In this study, we investigated the efficacy of poly-amino-β-cyclodextrin (PA-β-CD) microparticles in adsorbing and reducing specific xenobiotics and pharmaceuticals from aqueous solutions.

Enhancement of YPrSbM (M = Sn, Pb) Electrodes for Lithium- and Sodium-Ion Batteries by Structure Disordering and CNTs Additives.

The maximally disordered (MD) phases with the general formula YPrSbM (M = Sn, Pb) are formed with partial substitution of Y by Pr and Sb by Sn or Pb in the binary YSb compound. During the electrochemical lithiation and sodiation, the formation of YPrSbMLi and YPrSbMNa maximally disordered-high entropy intermetallic phases (MD-HEIP), as the result of insertion of Li/Na into octahedral voids, were observed. Carbon nanotubes (CNT) are an effective additive to improve the cycle stability of the YPrSbM (M = Sn, Pb) anodes for lithium-ion (LIBs) and sodium-ion batteries (SIBs).

A Facile and Efficient Bromination of Multi-Walled Carbon Nanotubes.

The bromination of multi-walled carbon nanotubes (MWCNT) was performed with vapor bromine in a closed vessel, and they were subjected to intensive stirring with a magnetic stirrer for up to 14 days. The efficiency of bromination was compared depending upon duration. The structure and surface of the crude and purified products were characterized by detailed physicochemical analyses, such as SEM/EDS, TEM, XRD, TGA, Raman, and XPS spectroscopies.

Structural and enhanced hydrogen storage properties of the LiMgSiAl phase.

The multicomponent alumosilicide LiMgSiAl (cubic, space group I-43d, cI76) belongs to the structural family based on the CuSi type. The Li atoms are ordered and occupy the site with symmetry 1 and the Mg atoms occupy the site with -4..

New quaternary carbide MgLiAlC as a disorder derivative of the family of hexagonal close-packed (hcp) structures and the effect of structure modification on the electrochemical behaviour of the electrode.

Magnesium alloys are the basis for the creation of light and ultra-light alloys. They have attracted attention as potential materials for the accumulation and storage of hydrogen, as well as electrode materials in metal-hydride and magnesium-ion batteries. The search for new metal hydrides has involved magnesium alloys with rare-earth transition metals and doped by p- or s-elements.
