Summary: High salt intake is a leading cause of dietary risk for death from noncommunicable diseases. In this study, citric acid-crosslinked chitosan (CsC) was used to prepare low-sodium salt microspheres (CsC-RF-NaCl) that could absorb Cl- and produce high-saltiness. The CsC-RF-NaCl microparticles exhibited excellent thermal stability, reduced Na+ content, and lower bioaccessibility, making them suitable for surface-salted foods.

Summary: The peculiarities of exciton dynamics in tetrapod-shaped CdTe/CdSe nanocrystals are revealed under different optical excitation conditions. The photoluminescence spectra show well-resolved excitonic bands from CdTe and CdSe parts of the tetrapod arms, as well as PL caused by indirect transitions of spatially separated charge carriers. The giant blue shift of the indirect transition emission band, caused by the exciton's space filling effect and modification of the energy level structure by the induced internal electric field, is demonstrated.

Summary: High-efficiency photoluminescence quaternary hexagon Zn-Cu-In-S (ZCIS) nanoplatelets (NPIs) were successfully synthesized via a two-step cation exchange method, with In2S3 NPIs serving as templates. The reaction temperature of In2S3 and the temperature of Cu addition were found to be crucial for tuning the properties of NPIs. Introducing Zn2+ enhanced the stability and optical properties of the resulting NPIs, demonstrating a new approach to synthesize high-efficiency and nontoxic ZCIS NPIs with no byproducts.

Summary: Copper chalcogenide-based nanocrystals (NCs) are promising alternatives to toxic Cd/Pb chalcogenide-based NCs in various applications. However, direct synthesis methods of this class of compounds suffer from inhomogeneities in size, shape, and composition. Partial cation exchange and synthetic strategies can improve control and narrow photoluminescence (PL) bandwidths. This study presents a two-step colloidal synthesis of Cu-Zn-In-Se (CZISe) NCs via partial cation exchange, resulting in gradient-alloyed CZISe NCs with a Zn-rich surface. The synthesized NCs exhibit high photoluminescence quantum yield (PLQY) and narrow PL bands, offering potential for solar energy harvesting and bioimaging applications. Rating: 8/10
