Aerogel Fiber: A One‐Dimensional Programmable Porous Matter for Next Thermal Management Materials

Interdisciplinary Materials, EarlyView.
Aerogel fibers are redefined as one‐dimensional programmable porous matter, where thermal transport is governed by multiscale pathway engineering. By reconstructing and decoupling transport pathways from molecular to textile scales, these systems integrate insulation, radiative cooling, and adaptive thermal regulation.

Multilevel octadecagonal space vector generation for induction motor drives by cascading asymmetric three level inverters

, 2012
Multilevel inverters with hexagonal and dodecagonal voltage space vector structures have improved harmonic profile compared to two level inverters. Further improvement in the quality of the waveform is possible using multilevel octadecagonal (18 sided ...

Van der Waals ferroelectric semiconductor tunnel junction with ultra‐low switching voltage

InfoMat, EarlyView.
Ferroelectric tunnel junctions are promising building blocks for energy‐efficient memory and brain‐inspired computing, but their practical use is limited by the relatively high voltages required for operation. Here, we develop an all‐two‐dimensional ferroelectric tunnel junction based on AgBiP2Se6 that enables reliable memory operation below 0.2 V and ...

Single‐Lens Counter‐Focused Ultrashort Laser Pulses for Enhanced Microplasma Formation Inside Silicon

Laser &Photonics Reviews, EarlyView.
A polarization‐dependent liquid–crystal spatial light modulator is used to generate coaxial double‐focus laser beams with independently tunable focal separation and intensity. Applied to silicon, this configuration enables counterpropagating pulse interactions using a single focusing element, enhancing nonlinear excitation and achieving near‐critical ...

Cellulose‐based films with ultralong full‐color circularly polarized room‐temperature phosphorescence and bidirectional dissymmetry tuning

Responsive Materials, EarlyView.
A universal co‐assembly strategy of CNCs, PVA and phosphorescent chromophores is proposed to fabricate CP‐RTP films with an ultralong lifetime of 1.588 s. FRET‐based dye doping enables full‐color CP‐RTP, and integration with an additional CNC‐based film enhances CPL and achieves tunable luminescence handedness, with the glum factor from −0.7782 to 0 ...
