Asia-Pacific Journal of Chemical Engineering, EarlyView.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

Frequency Selective Rasorber With Low Insertion Loss and Ultra‐Broadband Scattering Reduction
Advanced Physics Research, EarlyView.We present a dual‐polarization broadband frequency selective rasorber featuring a transmission window in the middle of its absorption band. The proposed FSR achieves a –10 dB reflection band over 3.68–16.94 GHz with a fractional bandwidth of 128.6%, featuring a minimum insertion loss of 0.3 dB at 10.3 GHz.

How Supply Networks Influence Sustainable Innovation: Evidence From Ghana's Public Works Procurement
Business Strategy and the Environment, EarlyView.ABSTRACT Recent environmental and sustainability standards in procurement increase short‐term production and operational costs to suppliers, which are often recouped by charging price premiums for innovative solutions. However, public buyers are less likely to pay such price premiums, resulting in a disincentive among suppliers to bid for innovation ...
