Single-site ruthenium catalyst supported on zeolite for CO2 hydrogenation to methyl formate

Paul Joseph Dyson, Victor Carle Adrien Boureau, Xunhui Wang, Roland Christopher Turnell-Ritson

Technologies for the transformation of atmospheric CO2 to useful chemicals, such as formic acid (FA), are essential to combatting excessive fossil fuel use and will need to be implemented on large scale. However, hydrogenation of CO2 to (base-free) FA is c ...

Polycondensation as a Universal Method for Preparing High-density Single-atom Catalyst Libraries

Mounir Driss Mensi, Paul Joseph Dyson, Daniel Ortiz Trujillo, Pascal Miéville, Miyeon Chang, Xinbang Wu, Xunhui Wang, Laura Piveteau, Ariana Serban, Timo Markus Oskar Felder, David Fernando Reyes Vasquez

Single-atom catalysts (SACs) present a promising subclass of classic heterogeneous catalysts by maximizing metal dispersion and enhancing efficiency. Although high-density SACs (HD-SACs) are reported, their synthesis is typically constrained to specific me ...

Bilayered polyurethane/dipole-dipole and H-bonding interaction reinforced hydrogels as thermo-responsive soft manipulators

Paul Joseph Dyson, Zhaofu Fei, Zhangjun Huang, Haiyan Jia, Xunhui Wang

Dipole-dipole and hydrogen-bonding interaction reinforced (DHIR) hydrogels that demonstrate both excellent thermo-responsive volume change and high mechanical strength have been developed. Their thermo-responsive volume change originates from the balance b ...

Unconventional Tough Double-Network Hydrogels with Rapid Mechanical Recovery, Self-Healing, and Self-Gluing Properties

Paul Joseph Dyson, Zhaofu Fei, Zhangjun Huang, Haiyan Jia, Xunhui Wang

Hydrogels are polymeric materials that have a relatively high capacity for holding water. Recently, a double network (DN) technique was developed to fabricate hydrogels with a toughness comparable to rubber. The mechanical properties of DN hydrogels may be ...

Cytotoxicity of ionic liquids and precursor compounds towards human cell line HeLa

Paul Joseph Dyson, Zhaofu Fei, Xunhui Wang

The toxicity of ethyl-, butyl-, octyl-, benzyl-, and allyl-substituted 1-alkyl-3-methylimidazolium, alkylpyridinium, N-alkyl-N,N-dimethyl-N-(2-hydroxyethyl)ammonium (choline derivs.) and alkyl-triethylammonium salts towards HeLa cells has been studied. The ...
