- Chromium-containing wastewater poses serious environmental and health issues due to pollution and toxicity.
- Researchers developed a fly ash loaded nano-FeS composite (nFeS-FA) to effectively adsorb and reduce chromium levels in contaminated water, analyzing factors like dosage, pH, and contact time.
- The study found that under optimal conditions, nFeS-FA removed approximately 88% of Cr(VI) and 72% of total Cr, with the adsorption process primarily driven by chemical interactions, offering a promising solution for water treatment applications.
Presently, there are several issues associated with solid waste fly ash, such as its accumulation and storage, low comprehensive utilization rate, lack of high-value utilization technology, environmental risk and ecological impact. Thus, based on the high silica content and adsorption characteristics of fly ash, two novel adsorbents, namely mesoporous silica-based material (MSM) and sodium dodecyl sulfate-modified fly ash (SDS-FA), were prepared using an ultrasound-assisted alkali fusion-hydrothermal method and surface modification method. Furthermore, effects of adsorbent dosage, initial pH, contact time, and initial concentration of the solution on the adsorption of the organic pollutant methylene blue (MB) by fly ash, MSM, and SDS-FA were investigated to select the optimal modified high silica fly ash adsorbent.

- * Various factors affecting the adsorption of Zn(II) and Cu(II), such as dosage, pH, stirring rate, reaction time, and initial concentration, were examined, achieving significant removal rates of 83.36% for Zn(II) and 70.40% for Cu(II).
- * The adsorption process was primarily chemical, fitting well with the Lagergren second-order kinetic equation and showing higher compatibility with the Langmuir isotherm model, indicating a monolayer adsorption mechanism, providing insights
Two new tetracopper(II) complexes bridged by N-benzoate-N'-[3-(diethylamino)propyl]oxamide (H3bdpox), and ended with 4,4'-dimethyl-2,2'-bipyridine (Me2bpy) or 2,2'-bipyridine (bpy), namely [Cu4(bdpox)2(Me2bpy)2](pic)2 (1) and [Cu4(bdpox)2(bpy)2](pic)2·2H2O (2) (where pic denotes the picrate anion) have been synthesized and characterized by X-ray single-crystal diffraction and other methods. In both complexes, four copper(II) ions are bridged alternately by the cis-oxamido and the carboxylato groups of two bdpox(3-) ligands to form a centrosymmetric cyclic tetranuclear cation, in which, the copper(II) ions at the endo- and exo-sites of cis-bdpox(3-) ligand have square-planar and square-pyramidal coordination geometries, respectively. The reactivity towards DNA/BSA suggests that these complexes can interact with HS-DNA through the intercalation mode and the binding affinity varies as 1>2 depending on the hydrophobicity, and effectively quench the fluorescence of protein BSA via a static mechanism.

- Allogeneic hematopoietic stem cell transplantation is a common and effective treatment for blood-related diseases, reliant on finding HLA-matched donors.
- A study examined HLA allele and haplotype distributions among 169,995 Chinese individuals, revealing the presence of many distinct alleles and significant regional variations in haplotype frequencies.
- This research, the first of its kind in China, provides valuable data for improving donor matching processes and contributes to understanding genetic diversity across different regions in the country.
