Picosecond Dynamics of Selective Ablation in a Ni/Al Multilayer Thin Film Induced by a Femtosecond Laser Pulse

In recent decades, high-precision processing with ultrashort laser pulses has been progressively applied in highly efficient surface modification technologies for new multilayer nanomaterials widely used in industry. In this work, the ultrafast dynamics of layer-by-layer ablation...

Multi-criteria selection of additives for CO2-based mixtures in solar-driven supercritical CO2 Brayton cycles: A critical review of performance, compatibility, and trade-offs

The supercritical carbon dioxide (sCO 2 ) Brayton cycle offers high efficiency and compactness for power generation. However, its integration with Concentrated Solar Power (CSP) in hot, arid regions is hindered by pure CO 2 's low critical temperature (31°C), which compromises co...

Flat interface between amorphous ices and the role of MDA-like intermediate states in the LDA–HDA transformation

The pressure-induced transformation between low-density amorphous ice (LDA) and high-density amorphous ice (HDA) is a prototypical polyamorphic transition, yet its microscopic mechanism-and in particular the nature of intermediate amorphous (IA) states-has long remained unresolve...

Curvature-induced smectic-C order of tangentially anchored hard spherocylinders on a sphere with a rigidly locked director field

We study the strict locked-orientation limit of hard spherocylinders on a sphere, in which the rod axes are rigidly locked to a prescribed tangential director field. The bulk hard-rod phase diagram contains no smectic-C (Sm-C) phase, so any coherent tilt found here is curvature-i...
