Solar-Enhanced Blue Energy Conversion via Photo-electric/thermal in GO/MoS/CNC Nanofluidic Membranes.

In recent years, light-controlled ion transport systems have attracted widespread attention, however, the use of photoresponsive materials suffers from rapid carrier recombination, thermal field limitations, and narrow spectral response, which significantly restricts their performance enhancement in osmotic energy conversion. This study innovatively couples "blue energy" (osmotic energy) with "green energy" (solar energy), assembling graphene oxide/molybdenum disulfide/sulfonated cellulose nanocrystal (GO/ MoS/CNC) ion-channel membranes. Under solar irradiation, the energy level difference between MoS and GO effectively suppresses the recombination of photogenerated carriers, generating more active electrons and significantly enhancing the carrier density, thereby improving the current flux and ion selectivity.

Confinement-Tailored High-Concentration Electrolytes in Metal-Organic Frameworks for Durable Lithium-Metal Batteries.

High-concentration electrolytes (HCEs) face inherent challenges such as high viscosity and diminished ionic conductivity caused by the formation of three-dimensional (3D) anion networks, which limit their practical applications. In this study, it is demonstrated that encapsulating HCEs within metal-organic frameworks (MOFs) effectively disrupts these 3-D networks, resulting in significantly enhanced ionic conductivity. Raman spectroscopy, nuclear magnetic resonance (NMR), and molecular dynamics (MD) simulations reveal a significant reduction in aggregates (AGGs)-state anion within MOF-confined electrolytes, confirming the reconstruction of the solvation environment.

In this paper, we focused on the question as to how melting entropy is associated with another classical glass formation criterion of molecule/atom size difference of components.
