Persistent Free Volume Governs (Anti-)plasticization in Chitosan-Water Mixtures

Using molecular dynamics simulations, this study reveals that the transition from antiplasticization to plasticization in chitosan-water mixtures is governed by the connectivity of dynamically accessible free volume regions, which modulates the competition between weakened polymer-polymer and enhanced polymer-water interactions to dictate the material's elastic properties.

Anomalous Platinum and Oxygen Transport during Electroforming of NbOx Memristors

This study reveals that electroforming in Pt/NbOx memristors induces a previously unrecognized, highly correlated redistribution of oxygen and platinum, where localized Joule heating drives the formation of a Pt-rich filament alongside an oxygen-enriched pathway, challenging the conventional view of noble metal electrode inertness.

Morphological Transition: From Meanders to Mound Structures

This study utilizes a vicinal Cellular Automata model to demonstrate that the morphological transition from meandered patterns to mound structures on crystal surfaces is governed by the competition between Ehrlich-Schwoebel barriers and adatom mobility, revealing a reversible pathway between these distinct growth regimes across varying deposition and diffusion conditions.

Thermal conductivity tuning of scalable nanopatterned silicon membranes measured with a three-probe method

This paper demonstrates a scalable method for significantly reducing the thermal conductivity of silicon membranes through block copolymer self-assembly and controlled nanohole etching, validated by a novel three-probe technique that overcomes thermal contact resistance challenges to achieve a fivefold reduction in thermal conductivity at room temperature.

Spin-Valley-Mismatched Altermagnet for Giant Tunneling Magnetoresistance

This paper establishes a predictive theoretical model for altermagnet-based spin transport and demonstrates through first-principles calculations that KV2_2Se2_2O/MgO/KV2_2Se2_2O magnetic tunnel junctions exhibit a robust, giant tunneling magnetoresistance exceeding 7.57×1077.57\times10^7\%, offering a promising candidate for next-generation room-temperature non-volatile memory.
