Design of Liquid–Air Hybrid Cooling Garment and Its Effect on Local Thermal Comfort

open access: yesApplied Sciences, 2023
Personal cooling garments were reported effective in improving thermal comfort in hot environments. In this study, three liquid–air hybrid cooling garments and one control garment were designed and made: aluminum-tube fan cooling (AAL), silicone-tube fan

Active Textile Glove for Cooling and Personal Protection [PDF]

open access: yesMicro, 2022
Conventional gloves partially insulate against heat transfer from a hot external environment. They also prevent metabolic heat generated by the human body from escaping. Thus, gloves are a source of heat buildup and heat stress in workers. Heat stress can lead to hyperthermia.

Ultra-stable self-foaming oils [PDF]

open access: yes, 2017
This paper is concerned with the foaming of a range of fats in the absence of added foaming agent/emulsifier. By controlling the temperature on warming from the solid or cooling from the melt, crystals of high melting triglycerides form in a continuous ...
