Embedded Direct‐Written Organic Micro‐TEGs for High‐Efficiency Skin‐Heat Harvesting

Advanced Electronic Materials, EarlyView.
A finite‐element–guided design of direct‐written organic micro‐thermoelectric generators is presented for efficient skin‐heat harvesting. Embedding PEDOT:PSS/PBFDO thermoelectric legs within flexible substrates suppresses interfacial heat losses and enhances vertical heat flow.

Correlation of Projected Flame Height for Impinging Horizontal Jet Flames

Chemical Engineering Transactions
Horizontal jet flame is said to be among the most dangerous types of fire considering a possible impingement effect on nearby facilities. Numerous studies have been conducted and assessed for geometrical flame features of jet flames as it imposed dangers where nearby equipment is included. However, data on flame height are often missing considering the

A Fast Method for Selecting Bio Sourced Materials of Interest in a Candle Formulation

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT As consumer demand shifts towards more sustainable and nontoxic alternatives, the candle industry is exploring unconventional bio‐based and recycled materials as substitutes for paraffin. Four raw materials, that is rice bran wax (RBW), sugarcane wax (SCW), hydrogenated rapeseed oil (HRO), and waste cooking oil (WCO) were assessed based on ...
