Investigation of flow dynamics across transonic compressor stage and inter-stage duct

Abstract The approaching threshold in the design and optimisation of rotating components in gas-turbine engines has drawn attention to the inter-spool duct (ISD) due to its potential to enhance the aerodynamic efficiency of compression systems. The ISD is a crucial passage to del...

Inverse design of realizable metasurface based absorbers using improved conditioning and diversity enhanced progressively growing GANs

Abstract Metasurfaces enable precise manipulation of electromagnetic (EM) waves for applications such as beam steering, sensing, and stealth technology. However, inverse design of metasurfaces remains challenging owing to the computational burden of iterative full-wave simulation...

Dynamic Covalent Porous Networks Enabling Synergistic Microwave Attenuation

Lightweight, adaptive, and porous microwave (MW) absorbers with reprocessability are highly desirable for next-generation portable electronics and sustainable electromagnetic interference (EMI) shielding systems. Herein, we report a one-pot strategy for fabricating three-dimensio...

Elucidating the role of noble metals in Ag- and Pd-modified TiO2 visible-light photocatalysts: Theoretical validation of experimental evidence

A combined experimental–theoretical understanding of the noble metal-modified TiO 2 photocatalysis for environmental remediation remains relatively unexplored. This study investigates the influence of silver (Ag) and palladium (Pd) modifications on the visible-light photocatalyti...
