Ceria: multifunctional catalytic material in non-reductive CO2 conversion and H2-driven deoxydehydration

Ceria is an essential component in the heterogeneous catalysis for non-reductive CO2 conversion and rhenium-catalyzed deoxydehydration (DODH). Ceria is an effective heterogeneous catalyst for the reactions such as alcohols+CO2, amines+CO2, and alcohols+amines+CO2 which give corresponding organic carbonates [1], urea derivatives [2], and carbamates [3]. When the...

Mechanochemistry for sustainable applications

Conventional reactions are mostly driven by heat, light, and electricity to overcome activation barriers. They are named as thermochemistry, photochemistry, and electrochemistry, respectively. Likewise, chemical reactions induced by mechanical actions, such as abrasion, friction, cracking, colliding, and so on, are defined as mechanochemistry. The most...

Nanoscale Surface Chemistry for Advancing Next-Generation Optoelectronics

Interfacial two- and three-dimensional heterostructures that incorporate ammonium ligand intercalation have enabled rapid progress toward the goal of uniting performance with stability in perovskite solar cells. However, as the field continues to seek ever-higher durability, additional tools that avoid progressive ligand intercalation are needed to...

Biodegradable Polymeric Nanoparticles as Biomedical Adhesives

Biodegradable polymer nanoparticles are synthesized using a membrane-assisted encapsulation technique [1], incorporating polyhydroxyalkanoates (PHAs) or poly(3-hydroxybutyrate-co-4-hydroxybutyrate, P(3HB-co-4HB)) into a chloroform-in-water emulsion, followed by chloroform evaporation. Precise control over the diameter of these PHA particles is achieved by adjusting the PHA concentration or emulsion diameter, and...
