The Physics of Core-Collapse Supernovae: Explosion Mechanism and Explosive Nucleosynthesis

open access: yesUniverse
Recent developments in multi-dimensional simulations of core-collapse supernovae have considerably improved our understanding of this complex phenomenon. In addition to that, one-dimensional (1D) studies have been employed to study the explosion mechanism and its causal connection to the pre-collapse structure of the star, as well as to explore the ...

Ultrafast Thermal Shock Synthesis of CuNiSnLa Medium‐Entropy Metallic Glass for Sustainable Nitrogen Fixation via Plasma‐Coupled Electrocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces an ultrafast thermal shock strategy to synthesize a CuNiSnLa medium‐entropy metallic glass (MEMG). The rapid heating and cooling process generates a robust, highly active catalyst for electrocatalytic nitrate reduction to ammonia (NRA).

Multifunctional Solid Polymer Electrolyte Films Integrating Intrinsic Self‐Healing and Dual Photo‐/pH‐Responsive Ionic Sensing for Intelligent Flexible Electronics

open access: yesAdvanced Functional Materials, EarlyView.
Multifunctional solid polymer electrolyte (SPE) films integrating intrinsic self‐healing, mechanical stretchability, and dual photo‐ and pH‐responsive ionic conductivity are developed. Constructed from thermoplastic polyurethane (TPU) and hydrogen‐bonded poly(thiourea triethylene glycol) (PTUEG3), these films form a dynamic supramolecular network ...

Study on the characteristics and mechanism of inert powder inhibition of gas/coal dust compound explosion

open access: yesMeitan kexue jishu
Gas/coal dust composite explosion is a complex process that combines homogeneous and heterogeneous combustion. The combustion main control mechanism changes dynamically and the explosion mechanism is more complex, resulting in higher explosion ...

Atomically Dispersed Ni Site Catalysts Accelerating Sluggish Sulfur Redox Kinetics in Nonaqueous Zn‐S Batteries

open access: yesAdvanced Functional Materials, EarlyView.
An atomically dispersed Ni catalyst featuring Ni‐N4 coordination is developed as a sulfur host for nonaqueous Zn─S batteries. This configuration modulates the electronic structure to lower activation barriers during rate‐limiting steps and promotes a robust ZnF2‐rich cathode‐electrolyte interphase, thereby accelerating sulfur redox kinetics ...

Sulfation‐Tunable Peptide‐Glycosaminoglycan Hydrogels for Hematopoietic Stem and Progenitor Cell Expansion

open access: yesAdvanced Functional Materials, EarlyView.
Co‐assembly of rationally designed glycosaminoglycan‐binding peptides with sulfated glycosaminoglycans yields supramolecular hydrogels with tunable mechanics and matrix‐mediated cytokine retention. The glycosaminoglycans thereby act as cofactors, driving a coil‐to‐β‐sheet transition that triggers gelation.

Design and Characterization of a Two‐Dimensional Soft Array Based on Cooperative Dielectric Elastomer Actuators

open access: yesAdvanced Functional Materials, EarlyView.
A fully polymeric two‐dimensional array of Dielectric Elastomers enables self‐sensing, cooperative actuation, and large‐stroke operation in a DE‐based autonomous conveyor. Based only on voltage and current measurements at actuator level, the system detects the presence of a ball and subsequently drives it toward a target position.

Solution‐Processed Mn‐Doped 2d Perovskite Wavelength Shifters for Noble‐Liquid Photon Detection

open access: yesAdvanced Functional Materials, EarlyView.
Solution‐processed Mn2+‐doped PEA2PbBr4 two‐dimensional perovskite films are demonstrated as large‐area wavelength shifters for noble‐liquid photon detectors. Mn2+ incorporation introduces a broad emission band at ∼620 nm with a large Stokes shift, suppressing self‐absorption and matching SiPM sensitivity.
