AbstractThe tungsten diselenide (WSe2) has attracted considerable interest owing to their versatile applications, such as p-n junctions, transistors, fiber lasers, spintronics, and conversion of solar energy into electricity. We demonstrate all-optical tuning of light in WSe2-coated microfiber (MF)

AbstractRespiratory rate is a critical biomarker for detecting respiratory disorders such as obstructive sleep apnea and cystic fibrosis. Conventional clinical monitors are bulky and unsuitable for everyday use, whereas mobile health devices require lightweight, power‑free solutions. We present a wa

Abstract We investigated the optical phonon modes of self‑catalyzed InP/InAs/InP core‑shell nanostructures—nanopillars and nanocones—grown on InP(111)B substrates via metal‑organic chemical vapor deposition (MOCVD) using liquid indium droplets as catalysts. Raman analysis revealed the first‑order mo

Using atomistic molecular dynamics, we examined the shape stability of body‑centered‑cubic (bcc) nanoplates with low‑index surfaces. Our simulations reveal that (110) surfaces are intri

AbstractUsing first‑principles calculations, we predict that penta‑siligraphene (P‑Si2C4) is a promising anode material for Li‑ion batteries. The hybrid Si/C structure is more thermally stable than penta‑graphene and possesses a buckled pentagonal lattice that hosts an empty C‑2pz band. This elect

AbstractTo broaden the commercial impact of organic light‑emitting diodes (OLEDs), solution‑processed inverted polymer LEDs (iPLEDs) are emerging as a promising platform. However, the electron‑transport efficiency of the cathode interface layer—specifically PF‑NR2—remains a bottleneck. In this study

The effects of MWCNT addition on the electrochemical performance of rGO/MWCNT nanocomposite films are investigated in some strong base aqueous electrolytes, s

AbstractThree‑dimensional porous nanostructures are increasingly attractive for flexible microsupercapacitors (MSCs) because they expose more electrochemical active sites, accelerate ion diffusion, and reduce charge‑transfer resistance. In this study, we fabricated a highly open 3‑D network of reduc

AbstractWe present a novel strategy to improve current spreading in AlGaN‑based deep ultraviolet light‑emitting diodes (DUV LEDs) by inserting a locally doped n‑AlGaN/p‑AlGaN/n‑AlGaN (NPN‑AlGaN) structure into the electron‑supplier layer. The thin p‑AlGaN insertion creates a conduction‑band barrier

AbstractIn this study, we propose a one-drop self-assembly method, which proved capable of successfully preparing 4-N, N-dimethylamino-4′-N′-methyl-stilbazolium tosylate (DAST) single-crystalline nanowires (NWs). The apparent roughness of the DAST NWs was determined to be less than 100 pm by using a
