Rocksalt high entropy oxide–enabled enhancement of redox kinetics in room-temperature sodium–sulfur batteries

As a next-generation energy storage technology, room temperature sodium sulfur (RT-NaS) batteries offer higher energy density, lower cost and raw material abundance compared to lithium-ion batteries. However, major challenges impeding practical applications are polysulfide shuttl...

Transformative Materials Research: Defining Conceptual Change across Scales

Abstract What qualifies as transformative materials research? In this Viewpoint, we use “transformative” to denote work that forces revision of underlying assumptions, enables generalization across systems, or reveals regimes inaccessible to existing frameworks. The term is widel...

Kinetic Effects on the Phase Behavior and Microstructural Transitions of a Thermoresponsive Polymer Solution

Abstract The thermoresponsive behavior of Pluronic F127 (PF127) triblock copolymer solutions is fundamentally governed by temperature-dependent micellization and complex self-assembly of these micelles. However, a comprehensive understanding of the temperature-dependent kinetics...

Reduced-Order Electrochemical Model for Coupled Three-Dimensional Flow Simulations of High-Temperature Polymer Electrolyte Membrane Fuel Cells

Abstract Accurate modeling of multiphysics systems presents significant computational challenges, particularly when addressing coupled transport phenomena across interfaces of multidomain systems with geometric complexities as in high-temperature polymer electrolyte membrane (HT-...

Automated Analog Layout Synthesis

Abstract In a world where analog design is becoming increasingly important, it is becoming increasingly important to provide solutions that can increase designer productivity by increasing the level of available automation. A particularly critical step is in generating the circui...

Harnessing Diazo Compounds as Alkoxycarbonyl Methylene Radical Linchpins: Truce–Smiles Rearrangement toward Amido Esters and Isoquinolinedione Scaffolds

Abstract The radical reactivity of acceptor-type diazo compounds is harnessed in the photochemical Truce–Smiles rearrangement of N-aryl-N-arylsulfonyl acrylamides to access β,β′-disubstituted amido esters. The rational design of starting materials and the cascade technique can be...

Water-State Reorganization as the Molecular Origin of the Thermo-Mechanical Anomaly in Hydrated Polymer Networks

Abstract Hydrated polymer networks are widely used across diverse environmental conditions, including varying humidity and temperature ranges, for numerous applications. The three distinct types of water present within hydrated polymer networks, namely tightly bound water, loosel...

Digital Twins in Oncology: From Multimodal Data Integration to Precision Clinical Practice

Oncology digital twins are patient-specific computational models that are built by combining electronic health records, multiomics genomic data, and diagnostic imaging to simulate individual tumor biology and predict multiple treatment-related outcomes. Conceptually originated fr...

Ontological Logic

I propose Ontological Logic as a foundational component of the broader Empirical-Axiomatic Framework (EAF) for analyzing existence, representation, logical structure, abstraction, and knowledge. The central distinction developed in this work is between an underlying existent or a...

Quantitative morphometry of the cervix using deep learning and geometric area estimation techniques

Abstract Objective Estimation of the actual cervix area observed during the colposcopy is a critical step towards accurate diagnosis, as hidden areas may lead to malignancy in the future. In the present study, an automated algorithm was developed that uses a deep learning segment...

Disentangling Elemental Roles in an Amorphous Medium‐Entropy Electrocatalyst for Oxygen Evolution

ABSTRACT Understanding elemental cooperation in high/medium‐entropy electrocatalysts is essential for rational design but remains challenging due to their compositional complexity. Herein, an amorphous medium‐entropy catalyst, FeCoNiMo‐a, with a nanoring architecture, is develope...

An exploration on what drives learners’ engagement in blended training at workplace

Purpose This study aims to identify and examine the key predictors of learners’ engagement (LE) in a blended learning (BL) training program. The goal was to assess the significance of perceived supervisor support on LE and examine the role of LE in their agility. Design/methodolo...

Updating the holomorphic modular bootstrap

A bstract We update the holomorphic modular bootstrap incorporating a recent result that computes the exact S -matrix within the Modular Linear Differential Equation (MLDE) setting. Further, using knowledge of the allowed exponents modulo one, we obtain admissible solutions to al...
