Adaptive Hybrid Energy Harvester Integrating PV, TEG, and Piezoelectric Sources With Real‐Time Power Management and Experimental Validation

Energy Science &Engineering, EarlyView.
An adaptive hybrid energy harvester combining photovoltaic, thermoelectric, and piezoelectric sources is experimentally demonstrated. Real‐time power management dynamically allocates and conditions multisource inputs, achieving improved robustness and efficiency under variable environmental conditions compared with single‐source harvesting.

Contribution of Free Fatty Acids to Emulsion Building and Stability: Understanding the Mechanism From the Case Study of a Crude Red Palm Oil (Elaeis guineensis)—Based Emulsion Consumed in Africa and Known as Achu Soup/Sauce Jaune/Ncha

Food Chemistry International, EarlyView.
In an aqueous alkaline medium, fatty acids (from the hydrolysis of triglycerides or freely present in the oil) are ionised in order to form emulsifiers (carboxylates) which will physically stabilise the prepared emulsion. The higher the free fatty acids content of the oil and alkalinity of the solution, the higher will be the stability of the prepared ...
