Chitosan, a naturally occurring biopolymer derived from chitin, has emerged as a highly promising instrument for the production and application of metal nanoparticles. The present review delves into the several functions of chitosan in the development and operation of metal nanoparticles, emphasizing its aptitudes as a green reducing agent, shape-directing agent, size-controlling agent, and stabilizer. Chitosan's special qualities make it easier to manufacture metal nanoparticles and nanocomposites with desired characteristics. Furthermore, there is a lot of promise for chitosan-based nanocomposites in a number of fields, such as metal removal, water purification, and photoacoustic, photothermal, antibacterial, and photodynamic therapies. This thorough analysis highlights the potential application of chitosan in the advancement of nanotechnology and the development of medicinal and environmental solutions.

III-V semiconductor nanocrystals (NCs) have emerged as a benign alternative to II-VI and IV-VI NCs, which are restricted due to the toxicity of the comprising elements. While InP NCs advanced significantly, the development of infrared-emitting InAs NCs has been relatively slow-paced. This is due to the synthetic challenges arising from the highly covalent bonding in InAs and the limited range of available arsenic sources.

Precious metal nanomaterials have demonstrated significant advantages in the field of alcohol electro-catalytic oxidation. In this study, the inexpensive main group metals lead (Pb) and platinum (Pt) have been innovatively selected to construct an alloy catalyst. By employing the solvent-thermal method, PtPb nanoparticles with a well-defined crystalline structure were successfully synthesized, exhibiting excellent performance.

Perovskite light-emitting diodes (PeLEDs) have emerged as a promising technology for next-generation display and lighting applications, thanks to their remarkable colour purity, tunability, and ease of fabrication. In this work, we explore the incorporation of plasmonic spherical nanoparticles (NPs) directly embedded into the green-emitting CsPbBr perovskite layer in a PeLED as a strategy to enhance both its optical and electrical properties. We find that plasmonic effects directly boost spontaneous emission while also influencing charge carrier recombination dynamics.

To overcome the persistent challenges of sluggish lithium polysulfide (LiPS) conversion kinetics and the shuttle effect in Li-S batteries, this work introduces a novel, cost-effective thermal treatment strategy for synthesizing high-entropy metal phosphide catalysts using cation-bonded phosphate resins. For the first time, we successfully fabricated single-phase high-entropy FeCoNiCuMnP nanoparticles anchored on a porous carbon network (HEP/C). HEP/C demonstrates enhanced electronic conductivity and superior LiPS adsorption capability, substantially accelerating its redox kinetics.

A novel phthalonitrile derivative (a) containing three functional groups (hexyl, aminated ester, phenoxy) was synthesized and subsequently cyclotetramerized in the presence of the corresponding metal chloride salts to obtain hexadeca-substituted metal {M = Cu(II) and Co(II)} phthalocyanines (b and c). The water-soluble phthalocyanines (d and e) were prepared by treating the newly synthesized complexes (b and c) with methyl iodide. Moreover, gold nanoparticles (1) and silver nanoparticles (2) were prepared, and their surfaces were modified with quaternary phthalocyanines (d and e).
