A novel approach has been adopted in the synthesis of nickel ferrite nanoparticles and their adsorption capacity was studied in the effective removal of MB dye from aqueous solution. Nanoparticles have a main advantage of treating large amount of wastewater within a short time and producing less contamination. The synthesized Spinel ferrites show high adsorption capacity, magnetic performance, and an eco-friendly material which effectively removes dyes.

Here, we provide a deeper insight into the state of sulfur confined in ultramicroporous carbon (UMC) and clarify its electrochemical reaction mechanism with lithium by corroborating the results obtained using various experimental techniques, such as X-ray photoelectron spectroscopy, electron energy loss spectroscopy, Raman spectroscopy, and electrochemical impedance spectroscopy. In combination, these results indicate that sulfur in UMC exists as linear polymeric sulfur rather than smaller allotropes. The electrochemical reactivity of lithium with sulfur confined in UMC (pore size ≤0.

Transition metal fluorides are an important class of cathode materials for lithium batteries owing to their high specific energy and safety. However, metal fluorides are electrical insulators, exhibiting slow reaction kinetics with Li. Consequently, metal fluorides can show poor electrochemical performance.

Article Synopsis
  • Genomics methods have greatly enhanced the understanding of Mendelian disorders, especially when combined with high-throughput functional-omics technologies, leading to better identification of genetic variants in families with recessive inheritance.
  • In a study of 99 individuals with abnormal Golgi glycosylation, 31 cases underwent whole-exome sequencing, revealing a known defect in 15 individuals, while unique glycomics signatures helped identify four patients with shared genetic markers.
  • Affected siblings had mutations in the SLC10A7 gene, leading to conditions like amelogenesis imperfecta and skeletal dysplasia, with studies in zebrafish and fibroblasts showcasing the gene's crucial role in bone mineralization and glycoprotein transport.

Lamin is an intermediate protein underlying the nuclear envelope and it plays a key role in maintaining the integrity of the nucleus. A defect in the processing of its precursor by a metalloprotease, ZMPSTE24, results in the accumulation of farnesylated prelamin in the nucleus and causes various diseases, including Hutchinson-Gilford progeria syndrome (HGPS). However, the role of lamin processing is unclear in fish species.
