Artificial intelligence–driven decoupling structure–activity relationship for lithium‐ion batteries
InfoScience, EarlyView.Artificial intelligence can efferently accelerate the high‐throughput screening of battery materials, the analysis of multiphase mechanisms, and the precise prediction of capacity and cycle life. This review systematically summarizes the applications of machine learning (ML) in decoupling the complex structure‐activity relationships of lithium‐ion ...

X-ray astronomy in the new millennium: a summary
Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2002 Recent X-ray observations have had a major impact on topics ranging from protostars to cosmology. They have also drawn attention to important and general physical processes that currently limit our understanding of thermal and nonthermal X-ray sources.

Near‐Infrared Polarimetric Imaging With Nonlinear Flat‐Optics
Laser &Photonics Reviews, EarlyView.ABSTRACT A compact and broadband polarimetric imaging platform is presented, based on second‐harmonic generation (SHG) in nonlinear flat‐optics. The system employs periodic all‐dielectric AlGaAs gratings to induce polarization‐dependent SH emission, enabling pixel by pixel direct retrieval of the full Stokes vector from an input intensity distribution ...

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement
Geophysical Monograph Series, Page 27-82., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Progress in Photovoltaics: Research and Applications, EarlyView.Front contact selection governs interfacial stability in CdTe‐based (Cd(Se,Te)) solar cells on ultra‐thin space‐qualified cover glass. Optimized TCO/emitter combinations suppress interdiffusion and deliver up to 16.2% AM0 efficiency with high specific power, demonstrating strong potential for lightweight space photovoltaics.
