Summary: Luminescent metal-organic frameworks (LMOFs) are promising for nanophotonic applications, but their 3D nature presents challenges. Metal-organic nanosheets (MONs) overcome these limitations by combining MOFs with an atomically thin morphology. This study reports the synthesis of thin ZIF-7-III MONs through low-energy salt-templating, which show intense and highly photostable fluorescence when intercalated with fluorophores. Aggregation and Forster resonance energy transfer are revealed as the mechanisms for fluorescence, providing quantified control over emission chromaticity.

Summary: The creation of yolk-shell nanoparticles (YS NPs) with a movable core and periodic mesoporous organosilica (PMO) shell has been simplified using a self-template strategy. A ratiometric Cu2+ fluorescence sensor is created by incorporating a silver nanocore into the YS NP (Ag-PMO-YS), driven by the like dissolves like principle. Due to the coordination of Cu2+ and its ligands and their impact on the emission of fluorescein derivatives, this sensor system demonstrates extraordinary detection sensitivity to Cu2+ (10-7 M), strengthened by the movable Ag nanocore's metal-enhanced fluorescence (MEF) effect.

Summary: This work investigates the plasmon resonances in gold and silver nanoparticles to enhance the luminescent properties of PMMA doped with different rare-earth ion densities. A rate equation model based on the Fo(r)ster theory is used to describe the luminescent dynamics between donor and acceptor rare earth ions and takes into account the electric field changes due to metallic nanoparticles. The results show that the luminescence of rare earth can be increased in the proximity of spherical gold and silver nanoparticles due to changes in the optical field and transition rates.

Summary: This study investigated the initial immune response to biodegradable silk fibroin (SF) hydrogels by developing a Forster/fluorescence resonance energy transfer (FRET)-based sensor to detect matrix metalloproteinase (MMP) activity. SF hydrogels modified with FRET-MMPS implanted in mice were found to be degraded by MMPs within 3 hours post-implantation, indicating a molecular-level biodegradation process that enabled immune cells to infiltrate and degrade the hydrogel. This study provides valuable insights into the early stages of immune response to biomaterials.

Summary: SiOC and SnS@SiOC composite materials were prepared by thermal pyrolysis method, while SnS was prepared by CTAB-assisted hydrothermal method. The presence of crystalline carbon phase in SiOC was confirmed by high-magnification TEM images. SEM and TEM images established the nanoplate-like morphology of SnS and the nanoparticle nature of silicon-oxy carbide. X-ray photoelectron spectroscopy validated the chemical state of elements in the SnS@SiOC composite. CV graphs showed that SiOC behaved non-faradic process, while SnS and SnS@SiOC composite exhibited a combined lithium-ion storage mechanism. The rate capability of SnS@SiOC composite was superior to SnS and SiOC electrode materials. The initial discharge capacity of SiOC, SnS, and SnS@SiOC was 1191 mAh g-1, 1007 mAh g-1, and 1315 mAh g-1 @ 0.1 A g-1, respectively. At a current density of 1 A g-1, SiOC, SnS, and SnS@SiOC composite provided the 1000th cycle discharge capacity of 196.8, 437.5, and 570 mAh g-1, respectively. After 800 cycles @ 5 A g-1, SnS and SnS@SiOC composite delivered a discharge capacity of 448.7 and 491.8 mAh g-1, with capacity retention of 94% and 90%, respectively. Silicon oxy carbide and SnS synergistically increase lithium-ion storage capacity and cycle stability for long-term energy storage and conversion applications.

Summary: Heteroatom doping is an efficient method to modify the electronic properties of carbon for better lithium storage capacity. Here, we report a straightforward approach to synthesize selenium-decorated honeycomb-like g-C3N4 (Se-H-g-C3N4) for the anode of a Li-ion battery. The Se doping significantly widened the gap between carbon sheets, providing more active sites for Li-ion storage and enhancing the diffusion rate. As a result, Se-H-g-C3N4 outperformed bulk g-C3N4 and honeycomb-like g-C3N4 (H-g-C3N4) in terms of rate capability and specific capacity.

Summary: This study presents the structural snapshots of Mycobacterium tuberculosis enolase as it catalyzes the conversion of PEP to 2PG. The researchers observed a novel alternate conformation of 2PG that likely facilitates its dissociation from the active site, and this conformation is different from the widely reported canonical conformation. Molecular dynamics studies and binding free energy calculations support the idea that the alternate conformation of 2PG affects metal ion coordination and hydrogen-bonding interactions, leading to increased flexibility of the active-site loops and aiding product release.
