Structural Role and Mechanical Impact of Zirconia in Lithium Disilicate Glass

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
The effect of ZrO2 addition on the structure, topology, and mechanical properties of lithium disilicate glass is investigated using topological constraint theory (TCT), molecular dynamics simulations, and experiments. Zirconia acts as a network former, increasing packing density, rigidity, hardness, and elastic modulus.

Lambert W Function-based Technique to Estimate and Compare Performance of Partially Shaded Series-parallel and Total-cross-tied Configured PV Array [PDF]

Renewable Energy Research and Applications
Partial shading condition (PSC) has a detrimental effect on the output performance of a photovoltaic (PV) system. The output performance of a partially shaded PV array depends not only on the pattern, intensity and location of the shadow but also on its ...

Experimental Characterization and Modeling of High Hole Mobility GeSn Quantum Wells: The Role of Alloy Disorder Scattering

Small Science, Volume 6, Issue 4, April 2026.
This study reports record‐high hole mobility in undoped GeSn quantum wells, validated through magnetotransport measurements. By modeling the transport properties, the authors discover that alloy scattering in their material is significantly weaker than predicted for random alloys and previously studied materials.

A Scalable Hierarchical Dynamic PV Array Reconfiguration under Partial Shading

Energies, 2023
Photovoltaic (PV) arrays are often affected by partial shading (PS), which can significantly reduce their power output. Dynamic reconfiguration is a promising technique for mitigating the negative effects of PS by adjusting the electrical connections of ...

RUVBL2 Regulates Microglia Metabolic Reprogramming to Mediate Stress Granules Aggregation Exacerbating Postoperative Delirium in Aged Mild Cognitive Impairment Rats

Aging Cell, Volume 25, Issue 4, April 2026.
RUVBL2 mediates stress granule aggregation by regulating microglial metabolic reprogramming, thereby exacerbating postoperative delirium in aged rats with mild cognitive impairment. ABSTRACT Postoperative delirium (POD) accelerates the transition from mild cognitive impairment (MCI) to Alzheimer's disease (AD) in elderly patients.

Development of a C5‐Azidoacetamide‐Modified 4‐Amino‐2,3‐Difluorosialic Acid Activity‐Based Probe for Labeling of Influenza A Neuraminidases

ChemBioChem, Volume 27, Issue 6, 27 March 2026.
We report DFSA5Az/DFSA5bio, C5‐azidoacetamide 4‐amino‐2,3‐difluorosialic acid activity‐based probes that trap influenza A viral (IAV) neuraminidases (NA) via a stabilized covalent Tyr‐sialosyl intermediate with hour‐scale reactivation. A bioorthogonal azide enables CuAAC (or one‐step biotin) tagging for activity‐dependent Western‐blot detection at ...
