Advancing sustainable air conditioning with CO2 heat pump and earth-air heat exchange integration

Case Studies in Thermal Engineering
The early development of refrigeration technology relied on natural refrigerants such as carbon dioxide (CO2), ammonia, and hydrocarbons. However, technical limitations and safety challenges led to their replacement by synthetic refrigerants.

Aquafaba (Chickpea Cooking Water) as a Natural Emulsifier in the Development of Plant‐Based Coffee Whitener

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT In this study, the possibility of using aquafaba powder, derived from chickpea cooking water, as a natural emulsifier in the formulation of plant‐based coffee whitener was evaluated. For this purpose, coffee whiteners, which are emulsion type products, are obtained by high‐shear mixing followed by high‐pressure homogenization of the aqueous ...

The Effects of Enzyme Pretreatment Extraction on Lipid Recovery With Normal Phase HPLC

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT With the increasing interest in the commercialization of microalgal fermentation‐based products, sustainable and efficient oil extraction methods have been developed for manufacturing and analytical testing. Due to the variability and resilience of micro‐algae cell walls, traditional lipid extraction methods such as Folch and Bligh and Dyer ...

Pracaxi Oil as a Potential Inhibitor of Fat Bloom

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Fat bloom is one of the major technological challenges faced by the chocolate industry, caused by the polymorphic transition from β2(V) to β1(VI) crystals in cocoa butter (CB). One strategy to slow down this polymorphic transition is the addition of lipids rich in very long chain fatty acids (VLCFA), such as behenic acid.

Degradation Mechanisms, Encapsulation‐Based Stabilization, and Analytical Detection of Vitamin A

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Vitamin A is an important lipid‐soluble micronutrient essential for vision, immune function, and overall growth and development. However, vitamin A is unstable and susceptible to environmental factors because of its conjugated structure and inherent chemical reactivity.

Advancements in CO2 Capture Technologies: A Review of Amine Absorption and Alternative Methods for Post‐Combustion Integration

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Carbon capture technologies are poised to become one of the primary focuses regarding the achievement of net‐zero emissions by the year 2050. In these technologies, particular attention is given to post‐combustion CO2 capture, which is more easily implemented at existing power stations and other industries.
