Article Abstract
Birefringence, an important optical performance parameter for optoelectronic functional materials, is mainly influenced by the types of anion groups and their spatial arrangement. Inspired by the relationship between the structure and properties of chalcogenides, combined with the dimensional transformation, we successfully synthesized a sulfide compound (CsZnSnS) with a two-dimensional layered structure and a large birefringence. The experimental results showed that, compared with RbZnSnS, CsZnSnS achieved the structural transition from a zero-dimensional arrangement to a two-dimensional lamellar arrangement and achieved a breakthrough of birefringence from 0 to 0.12, which was determined by both experiments and first-principles calculations. These findings demonstrated that CsZnSnS was a potential birefringent material and provided instructions for the study of the synthesis of birefringent materials.

Obesity treatment requires an individualized approach, emphasizing the need to identify metabolic pathways of diagnostic relevance. Toll-like receptors (TLRs), particularly TLR2 and TLR4, play a crucial role in metabolic disorders, as receptor deficiencies improves insulin sensitivity and reduces obesity-related inflammation. Additionally, hydrogen sulfide (HS) influences lipolysis, adipogenesis, and adipose tissue browning through persulfidation.

Inorganic photochromic materials offer several advantages over organic compounds, including relatively inexpensive and higher thermal stability. However, tuning their color with the same component has remained a significant challenge. In this study, we demonstrate that the photochromic color of Cu-doped ZnS nanocrystals (NCs), which is initially pale yellow before light irradiation, can be tuned from gray to brown by adjusting the surface stoichiometry of Zn and S, which is controlled through the use of thiol and non-thiol ligands.

Sulfur-containing small molecules, mainly including cysteine (Cys), homocysteine (Hcy), glutathione (GSH), and hydrogen sulfide (HS), are crucial biomarkers, and their levels in different body locations (living cells, tissues, blood, urine, saliva, ) are inconsistent and constantly changing. Therefore, it is highly meaningful and challenging to synchronously and accurately detect them in complex multi-component samples without mutual interference. In this work, we propose a steric hindrance-regulated probe, NBD-2FDCI, with single excitation dual emissions to achieve self-adaptive detection of four analytes.

In this paper, we offer a unique green synthetic approach for producing iron sulfide quantum dots (FeS QD)-chitosan composites using gel chemistry. The technique uses the environmental features of chitosan, a biocompatible and biodegradable polysaccharide, and the excellent electrical properties of FeS QDs. By sustainable chemistry principles, the synthesis process is carried out under gentle settings, using aqueous solutions and avoiding hazardous solvents and strong chemicals.

Odor emissions, primarily from anthropogenic activities like waste treatment and industrial processes, pose significant challenges in urban areas, particularly near water resource recovery facilities. While these emissions are generally not toxic, they can adversely affect community wellbeing and investment, prompting stricter regulations in some regions. For example, New York State's hydrogen sulfide guidelines are more stringent than federal standards.
