EnergiesSlow market development has caused the lack of low-GWP A1 refrigerants for ultra-low temperature (ULT) refrigeration. Consequently, the high-GWP refrigerant R23 (GWP = 14,600) remains widely used within the ULT sector.

An Edible H2O2 Biosensor for Gastrointestinal Metabolites and Peroxidase Enzyme Quantification
Advanced Healthcare Materials, EarlyView.We present an edible biosensor for gastric fluid analysis that integrates a caffeic acid–horseradish peroxidase redox system into an edible electrolyte‐gated transistor. The device enables rapid, low‐volume detection of H2O2 and, with minimal modification, metabolites and enzyme activity in simulated gastrointestinal conditions.

Advanced Healthcare Materials, EarlyView.We developed a novel copper‐doped aluminum nano‐adjuvant (CuNA) to overcome cytarabine resistance in acute myeloid leukemia (AML). CuNA effectively sensitizes drug‐resistant AML cells to cytarabine by inducing mitochondrial dysfunction and inhibiting HMGCR/GPX4 to amplify ferroptosis.

Performance of a transcritical carbon dioxide heat pump for simultaneous refrigeration and water heating : a thesis presented in partial fulfilment of the requirements for the degree of Master of Technology at Massey University [PDF]
, 1998 Many industrial processes require both refrigeration to less than 0°C and water heating to greater than 60°C. Traditional independent refrigeration and boiler systems have relatively poor energy efficiency, whilst conventional heat pumps can provide both

Skin‐Interfaced Therapeutic Patches for Wound Fluid Management and Transdermal Drug Delivery
Advanced Healthcare Materials, EarlyView.This study presents an integrated skin‐interfaced device combining microfluidics, hydrogel film technology, flexible electronics, and iontophoresis‐based transdermal delivery of PDRN to enhance wound healing. The device effectively manages wound fluid, maintains optimal moisture, and non‐invasively delivers therapeutic drugs.

Advanced Healthcare Materials, EarlyView.The biomimetic nanoplatform IMNP (ETS1 pDNA/PBAE@ITP‐MM) undergoes targeted disassembly at inflammatory vascular sites to release the ETS1 plasmid (pETS1). This release initiates a cascade of effects that inhibit pathogenic pathways and support immune homeostasis. (Abbreviations: EndMT, endothelial‐to‐mesenchymal transition; EC, endothelial cell; TC, T
