Monodisperse Pd nanocubes of 20 nm rib length and Pd nanospheres of 3 nm diameter deposited on corundum were used as efficient tool to reveal structure sensitivity of three-phase hydrogenations of unsaturated alcohols. For an olefin alcohol hydrogenation in the kinetic regime, surface (100) atoms...

High resolution and high efficiency biomolecular sensing using solid-state and hybrid bilayer MoS2 nanopores
DownloadFall 2021
Solid-state nanopores have emerged as stable label- and amplification- free biosensors for rapid detection of charged biomolecules. Analytes are electrophoretically pulled through nanopores and are detected using the characteristic blockade current due to the translocation. However, despite their...

Suppression of addition reactions of asphaltene model compound during hydrogenation with sulfided iron catalyst
DownloadFall 2013
A model compound is used to probe the chemical and physical behaviors of asphaltene. Hydrogenation reactions were conducted in a batch microreactor at 430℃, 13.9 MPa H2 for 30 min using a solution of 1,3,6,8-tetrahexylpyrene in tetralin. Sulfided iron was prepared on α-alumina, γ-alumina and...
