Developments in the Use of Lipase Transesterification for Biodiesel Production from Animal Fat Waste

Applied Sciences, 2020
Biodiesel constitutes an attractive source of energy because it is renewable, biodegradable, and non-polluting. Up to 20% biodiesel can be blended with fossil diesel and is being produced and used in many countries.

Fatty acid methyl esters yield and phorbol esters degradation during transesterification of Jatropha curcas oil by alkaline, acid and enzyme catalyzed method

Renewable Energy and Environmental Sustainability, 2017
Jatropha curcas has recently been the focus of intense research as a raw material of biomass fuel. However, the carcinogenesis promoter action of the phorbol esters in the Jatropha raises concerns for health and environmental risk.

Intensification and optimization of biodiesel production using microwave-assisted acid-organo catalyzed transesterification process

Scientific Reports, 2020
To produce biodiesel cost-effective, low-cost, high free fatty acid (FFA) oil feedstock is desirable. But high FFA creates difficulty during the base-catalyzed transesterification process by yield loss due to the formation of soap.

Deciphering the Self-Catalytic Mechanisms of Polymerization and Transesterification in Polybenzoxazine Vitrimers

Journal of the American Chemical Society
The use of internal catalysts has emerged as a pivotal design principle to facilitate dynamic exchanges within covalent adaptable networks (CANs). Polybenzoxazines, specifically, have shown considerable potential in generating vitrimers through thermally

Microwave-assisted transesterification of sour cherry kernel oil for biodiesel production: comparison with ultrasonic bath-, ultrasonic probe-, and ohmic-assisted transesterification methods

Grasas y Aceites
In this study, sour cherry kernel oil was converted to biodiesel by microwave-assisted transesterification. Evaluations were made of several variables, namely, reaction time (1, 2, 3, 4, and 5 min), microwave power (100, 200, 300, 400, and 500 W ...

Multicatalytic Access to Renewable Poly(Silyl Ether)s with Tunable Properties

Angewandte Chemie, EarlyView.
This work presents a one‐pot, multicatalytic approach that combines magnesium‐catalyzed esterification and borane‐mediated hydrosilylation for the synthesis of partially bio‐based poly(silyl ethers). This method allows for the tuning of thermal and mechanical properties, including exceptional extensibility (>3800%), and enables efficient chemical ...

Electroactive Liquid Crystal Elastomers as Soft Actuators

Advanced Functional Materials, EarlyView.
Electroactive liquid crystal elastomers (eLCEs) can be actuated via electromechanical, electrochemical, or electrothermal effects. a) Electromechanical effects include Maxwell stress, electrostriction, and the electroclinic effect. b) Electrochemical effects arise from electrode redox reactions.
