Qibla Direction Accuracy in Bangka Belitung Mosques: An Astronomical–Geospatial Study
Accurate Qibla orientation is essential for the validity of Muslim prayer; inconsistencies in both traditional and modern determination methods continue to produce significant inaccuracies, particularly in archipelagic regions.

Perovskite/silicon tandem solar cells offer efficiencies beyond 30%, yet conventional architectures face trade‐offs between optical performance and current matching. Three‐terminal tandems employing silicon back‐contact bottom cells eliminate the current‐matching constraint while minimizing optical losses, offering superior energy yield under real ...

High Cooling Rate for LRE123 Stoichiometry Control in Preparation of High‐Tc Bulk Superconductors
This review presents the cooling‐rate‐control melt‐growth (CRCMG) method as an effective strategy for regulating LRE123 cation stoichiometry. By accelerating the cooling rate during crystallization, oxygen vacancies are increased in the growing lattice, which suppresses LRE3+/Ba2+ substitution and yields near‐ideal 1:2:3 stoichiometry with enhanced ...

Artificial intelligence–driven decoupling structure–activity relationship for lithium‐ion batteries
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 ...

Near‐Infrared Polarimetric Imaging With Nonlinear Flat‐Optics
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 ...

Tunable Terahertz Generation in Dispersion‐Engineered ZnTe Waveguides
A dispersion‐engineered Zinc Telluride (ZnTe) slab waveguide platform enables tunable and efficient guided‐wave terahertz (THz) generation through modal phase matching. By tailoring the optical and THz modal dispersion, coherent THz emission is achieved across 0.1–3 THz.
