ABSTRACT This study investigates binary zeotropic mixtures of R744 (CO₂) blended with eco‐friendly refrigerants for medium‐high temperature heat pumps, comparing them with conventional R744/R134a systems. All mixtures meet 60–80 K temperature lift requirements under low‐temperature conditions. A genetic algorithm optimized system parameters using fixed

ABSTRACT The growing impacts of climate change and energy scarcity demand environmentally sustainable refrigeration solutions. This study investigates eco‐friendly refrigerants (R152a, R290 and R600a) and their optimized ternary mixture as alternatives to R134a. Four blend compositions were analysed using experimental testing and REFPROP 10.0 modelling

Atomically Thin Sieves: Two‐Dimensional Materials for Membrane Separation
Atomically thin membranes derived from 2D materials overcome the inherent selectivity‐permeability trade‐off in conventional separation technologies. This perspective elucidates transport mechanisms for gases, water, and ions, surveys fabrication strategies including top‐down pore engineering and bottom‐up synthesis, highlights recent experimental and ...
