Mitigating Structural Degradation in Hydrated V2O5 for Proton Batteries through Nanoconfinement with a Holey Graphene Matrix

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
HrGO‐supported and confined water‐assisted synergy for faster proton transport in the V2O5 resulted in ultra‐long life over 10 000 cycles at high current density of 1 A g−1. A reaction kinetics study of the ultra‐long cyclability via first principle DFT calculation is also presented. Proton‐based electrochemistry offers a promising solution to the cost

Flexible multidimensional sensor for comprehensive human motion monitoring and recognition

open access: yesFlexMat, EarlyView.
A flexible multidimensional sensor based on orthogonally stacked nanofibrous films enables simultaneous detection of in‐plane strain (X/Y) and out‐of‐plane pressure (Z). The ultrathin device exhibits high sensitivity, wide strain range, and excellent directional selectivity.

Characterization, in vitro release, and antioxidant activity of glutenin hydrolysate encapsulated in liposome‐loaded uni‐axial and co‐axial electrospun fibers

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Bioactive peptides derived from protein hydrolysates provide various health benefits; however, their practical application is limited by low gastrointestinal stability, enzymatic degradation, and poor intestinal absorption. Overcoming these challenges remains a key bottleneck for oral peptide delivery.

Machine learning model identifies tibial anatomical variables as potential risk factors for anterior cruciate ligament injury

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The tibial slope is a well‐known risk factor for anterior cruciate ligament (ACL) injury. As machine learning continues to progress, it has become an increasingly explored tool for clinical screening and risk factor analysis. This study aims to develop and validate a prognostic machine learning model to predict the outcome of ACL ...

Predefined‐Time Dynamic Surface Control of Tank Horizontal Stabilization System With Disturbance

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Modern new tanks are difficult to achieve high precision control of the horizontal stabilization system due to electromechanical coupling and road surface disturbance during high‐speed combat. A predefined‐time dynamic surface controller (DSCPT) is proposed for the fast stabilization and strong disturbance problems of the tank horizontal ...
