Researchers present HEGAT, the first interpretable, fine-grained model that jointly predicts document-level event factuality and extracts evidential sentences, achieving SOTA on their refined EB-DEF-v2 corpus.

Scientists at the University of Connecticut have developed a handheld ‘pocket microscope’ that directly visualizes DNA and proteins in living cells without stains or labels. The system uses deep-ultraviolet light to map molecules with femtogram sensitivity, achieving 308-nanometer resolution across centimeter-wide areas. The device enables instant pathology diagnosis, identifies cancer cells, and maps brain neurons -- all while preserving samples’ natural state. This technology could transform medical diagnostics, from operating rooms to space missions.

In International Journal of Extreme Manufacturing, researchers have created a new class of ultrathin hydrogel electrodes that could finally make long-term wearable health monitoring practical, bringing the promise of 24/7 and high-fidelity health monitoring closer to reality.

The electric double layer (EDL) at the electrochemical interface is crucial for ion transport, charge transfer, and surface reactions in aqueous rechargeable zinc batteries (ARZBs). However, Zn anodes routinely encounter persistent dendrite growth and parasitic reactions, driven by the inhomogeneous charge distribution and water-dominated environment within the EDL. Compounding this, classical EDL theory, rooted in mean-field approximations, further fails to resolve molecular-scale interfacial dynamics under battery-operating conditions, limiting mechanistic insights. Herein, we established a multiscale theoretical calculation framework from single molecular characteristics to interfacial ion distribution, revealing the EDL’s structure and interactions between different ions and molecules, which helps us understand the parasitic processes in depth. Simulations demonstrate that water dipole and sulfate ion adsorption at the inner Helmholtz plane drives severe hydrogen evolution and by-product formation. Guided by these insights, we engineered a “water-poor and anion-expelled” EDL using 4,1',6'-trichlorogalactosucrose (TGS) as an electrolyte additive. As a result, Zn||Zn symmetric cells with TGS exhibited stable cycling for over 4700 h under a current density of 1 mA cm⁻², while NaV₃O₈·1.5H₂O-based full cells kept 90.4% of the initial specific capacity after 800 cycles at 5 A g⁻¹. This work highlights the power of multiscale theoretical frameworks to unravel EDL complexities and guide high-performance ARZB design through integrated theory-experiment approaches.

In the International Journal of Extreme Manufacturing, researchers use a nickel–titanium shape memory alloy shaped through laser powder bed fusion (LPBF) to create tiny and wavy structural features only 0.3 millimeters across, much smaller and more controlled than what is typically possible in metal metamaterials.

This review article systematically summarizes research progress on pressurized oxy-fuel combustion system designs, heat transfer mechanisms, combustion behavior, and pollutant emissions.
