Lanthanides, which are part of the rare earth elements group have numerous applications in electronics, medicine and energy storage. However, our ability to extract them is not meeting the rapidly increasing demand. The discovery of the bacterial periplasmic lanthanide-binding protein lanmodulin spurred significant interest in developing biotechnological routes for lanthanide detection and extraction.

Copper-based halides have attracted significant attention due to their unique photophysical properties and diverse coordination configurations. However, enhancing water stability and modulating structural transitions in cuprous halide materials remain challenging. In this work, we successfully synthesized three copper(I) halides, (CHP)CuBr (L1, [CHP] = hexyltriphenylphosphonium), (CHP)CuBr (L2), and (CHP)CuI (L3), via solvent volatilization, demonstrating exceptional water stability even after 27 days of submersion.

A fluorescence probe for "switch-on" detection of alkaline phosphatase (ALP) was developed based on Au nanoclusters anchored MnO nanosheets (Au NCs-MnO NSs), which were synthesized using bovine serum albumin (BSA) as template through a simple one-pot approach. In the sensing system, MnO NSs function as both energy acceptors and target identifiers, effectively quenches the fluorescence of Au NCs via fluorescence resonance energy transfer (FRET). The presence of ALP catalyzes the hydrolysis of L-ascorbic acid-2-phosphate (AAP) to ascorbic acid (AA), reducing MnO NSs to Mn and facilitate the fluorescence recovery of Au NCs.

Kwangwoon University, 20 Kwangwoonro Nowon-Gu Seoul, Nowon-gu, 01897, Korea (the Republic of).
To implement a neuromorphic computing system capable of efficiently processing vast amounts of unstructured data, a significant number of synapse and neuron devices are needed, resulting in increased area demands. Therefore, we developed a nanoscale vertically structured synapse device that supports high-density integration. To realize this synapse device, the interface effects between the resistive switching layer and the electrode were investigated and utilized.

To evade legal controls, new psychoactive substances (NPS), which have been designed as substitutes for traditional and synthetic drugs, are gradually dominating the drug market. Synthetic cannabinoids (SCs), which account for the majority of NPS, are rapidly being derivatized; consequently, controlling increasing abuse by merely listing individual compounds is difficult. Therefore, China has included the entire SC category of SCs listed as legal controlled substances since July 1, 2021.
