Pulse Generation by On‐Chip Dispersion Compensation at 8 µm Wavelength

Laser &Photonics Reviews, EarlyView.
This work demonstrates on‐chip pulse generation at 8 μm$\mathrm{\mu}\mathrm{m}$ using chirped Bragg gratings in SiGe graded‐index photonic circuits to compensate the quadratic phase of quantum cascade laser frequency combs. With this approach pulses as short as 1.39 ps were produced, close to the transform limit, representing a key step toward compact,

One‐Step Solvothermal Synthesis of VS4@PC/rGO for High‐Performance Symmetric Supercapacitors

MetalMat, EarlyView.
VS4@PC/rGO ternary composites featuring a 3D skewer‐like structure have been synthesized via a facile one‐step in situ solvothermal approach. The assembled SSC device has a 1.4 V voltage window, achieves 46.1 Wh·kg−1 energy density at 374.8 W·kg−1, and demonstrates excellent long‐cycle stability.

Zinc Oxide‐Based Nanocomposite Photoelectrodes for Photoelectrochemical Water Splitting: A Review on Structural Modifications and Performance Optimization

Nano Select, EarlyView.
Zinc oxide (ZnO) is highlighted as a highly potential photoanode material owing to its unique properties and multifunctionality. Thorough investigations are conducted for the enhancement of ZnO photoelectrodes, including doping, semiconductor coupling, defect engineering, and the inclusion of metallic nanoparticles.

Numerical Analysis of AgInSe2‐Based Thin‐Film Solar Cells Towards High Efficiency

Nano Select, EarlyView.
In this work, SCAPS‐1D is used to numerically explore AgInSe2‐based thin‐film solar cells. Using CuS, WSe2, and AlSb as back surface field (BSF) layers with a CdS window improves carrier separation and built‐in potential. AgInSe2's promise for high‐performance, stable, and environmentally friendly solar applications is demonstrated by the optimised CdS/
