Transition Metal Dichalcogenide Multijunction Solar Cells Toward the Multicolor Limit
Solar RRL, Volume 10, Issue 13, 15 July 2026.A thermodynamic design framework reveals how transfer‐printable TMD multijunction solar cells approach the multicolor limit. Within the 1.0–2.1 eV TMD bandgap window, a five‐junction ladder nears the efficiency plateau, while radiative efficiency, luminescent coupling, excitonic absorption, and bottom‐cell stability set the practical headroom for van ...

Compression of Multichannel Signals With Irregular Sampling Rates and Data Gaps
IEEE AccessIn this work, we study the compression of multichannel signals with irregular sampling rates and data gaps. We consider state-of-the-art algorithms, which were originally designed to compress gapless signals with regular sampling, adapt them to operate ...

Planar Solid‐State Nanopores Toward Scalable Nanofluidic Integration Based on CMOS Technology
Advanced Engineering Materials, Volume 28, Issue 13, 8 July 2026.We present a scalable silicon‐based fabrication strategy for planar solid‐state nanopores to enable their integration with complex nanofluidic systems. Prototype devices demonstrate normal voltage‐current characteristics, good noise performance, and appreciable streaming currents. Our CMOS‐compatible fabrication process offers precise geometric control

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Low frequency sound can travel great distances in planetary atmospheres. When these waves reflect off the air/ground interface, energy may be absorbed or transferred to mechanical waves in the subsurface. This study describes the direct and reflected acoustic wave generated by the re‐entry of the OSIRIS‐REx Sample Return Capsule captured on a ...

Near-lossless data compression
, 1998 Near-lossless data compression algorithm and its applications are investigated in this thesis. Near-lossless data compression is an alternative to the lossless compression scheme. The near-lossless compression techniques studied give quantitative measure

Strong Mode Coupling and Maximum Directional Absorption in Reciprocal Bianisotropic Metasurfaces
Nanophotonics, Volume 15, Issue 12, 25 June 2026.Symmetry breaking in q‐BIC dielectric metasurfaces enables strong electromagnetic coupling between electric and magnetic modes, leading to their hybridization and Rabi‐like splitting. This mechanism produces pronounced reciprocal bianisotropy and dual‐band asymmetric absorption under opposite illumination directions, offering a compact framework for ...

Magnetically Reconfigurable Mode Strong Coupling Toward Tunable Nanophotonic Sensing Devices
Nanophotonics, Volume 15, Issue 12, 25 June 2026.A magnetically reconfigurable metasurface realizes tunable strong coupling between structural and magneto‐structurally induced q‐BIC resonances without changing device geometry. The resulting hybrid branches enable high‐sensitivity refractive‐index sensing with noncontact active control, large figure of merit, and multiple resonance observables ...
