Retrofit of lower GWP alternative R449A into an existing R404A indirect supermarket refrigeration system [PDF]
, 2017 R404A is going to be phased out from most of the commercial refrigeration systems due to its high GWP value of 3943. R449A (GWP of 1282) has been proposed to replace R404A with only minor system modifications in supermarkets.

Experimental Analysis of Alternate Refrigerant Mixtures in Refrigeration System
E3S Web of ConferencesThis study focuses on conducting experimental analyses to assess the impact of alternative refrigerant blends within a vapor compression refrigeration system, with the aim of replacing the existing R134a refrigerant. These refrigerant blends are formulated by combining R600a, R1270, and R290 in four distinct mixing ratios.

Advanced Materials Interfaces, EarlyView.Lipid drug carriers to which ultra‐small gold nanoparticles were added enabled more efficient radiotherapy of cultured pancreatic cancer tumors. These nanoparticles boosted radiation‐induced damage to tumors by generating more reactive molecules, though higher gold levels are needed for strong benefits.

A Comprehensive Review of Waste‐Derived Materials for Solar Still Performance Enhancement
Advanced Materials Interfaces, EarlyView.ABSTRACT Solar desalination reduces energy use and produces freshwater sustainably, but its productivity is limited and cannot meet rising demand. Thus, solar desalination system improvements are sought to boost water productivity. Waste materials are abundantly available and burden the environment, making them low‐cost enhancers for solar desalination
