Artificial Cell Catalysts for Biotransformation: Design Principles and Process Integration

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Artificial cell catalysts are emerging as programmable biocatalytic platforms for sustainable molecular conversion. By reconstituting enzymes and functional modules within synthetic compartments, they combine the selectivity of biological catalysis with the design flexibility of synthetic materials.

Palladium/Graphitic Carbon Nitride (g-C3 N4 ) Stabilized Emulsion Microreactor as a Store for Hydrogen from Ammonia Borane for Use in Alkene Hydrogenation.

Angewandte Chemie, 2018
Direct hydrogenation of C=C double bonds is a basic transformation in organic chemistry which is vanishing from simple practice because of the need for pressurized hydrogen. Ammonia borane (AB) has emerged as a hydrogen source through its safety and high

Synthesis of piperidine and pyrrolidine derivatives by electroreductive cyclization of imine with terminal dihaloalkanes in a flow microreactor

Beilstein Journal of Organic Chemistry, 2022
We have successfully synthesized piperidine and pyrrolidine derivatives by electroreductive cyclization using readily available imine and terminal dihaloalkanes in a flow microreactor. Reduction of the substrate imine on the cathode proceeded efficiently

Modeling of process intensification of biodiesel production from Aegle Marmelos Correa seed oil using microreactor assisted with ultrasonic mixing.

Ultrasonics sonochemistry, 2019
Conventionally, the batch type reactors were used for the production of biodiesel. However, in recent years, the usage of microreactors has started emerging as a significant substitute for biodiesel production due to its higher conversion rate at a short

Scale‐Down Platforms for Process‐Oriented Enzyme Screening Using Microfluidics

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Enzyme screening platforms are typically evaluated based on their throughput and analytical performance rather than their ability to mimic the conditions encountered at large scale. In bioreactors, enzymes experience gradients in substrate concentration, oxygen availability, pH, temperature, and interfacial exposure, caused by imperfect mixing

Immobilization of Alginate Microbeads With Whole‐Cells Expressing Nitrilase for Continuous Nicotinic Acid Production in Chip Millireactor

Biotechnology and Bioengineering, EarlyView.
ABSTRACT The biocatalytic production of nicotinic acid using nitrilases has emerged as a promising alternative to conventional chemical synthesis, offering improved selectivity and environmental sustainability. In this study, we developed a continuous‐flow millireactor system employing Escherichia coli cells expressing a nitrilase from Paraburkholderia

Accelerating green heterocyclic synthesis: Convergence of AI, automation, and sustainable chemistry

Bulletin of the Korean Chemical Society, EarlyView.
Green heterocyclic synthesis and data‐driven tools such as AI, high‐throughput experimentation, continuous flow, and self‐driving laboratories have developed largely in parallel. This review connects them and asks how green metrics such as E‐factor and PMI might serve as explicit optimization targets rather than post‐hoc measures, toward sustainable ...
