In this study, a novel facet‐junction strategy is proposed to enhance the strong metal‐support interaction (SMSI) between the loaded Ru atoms and the Co3O4 support. The synthesized structure with the incorporation of Ru doping and the (100)/(111) crystal plane junction has a particular influence on the catalyst's hydrogen evolution reaction (HER ...

Direct Observation of Early-stage Quantum Dot Growth Mechanisms with High-temperature Ab Initio Molecular Dynamics [PDF]
Colloidal quantum dots (QDs) exhibit highly desirable size- and shape-dependent properties for applications from electronic devices to imaging. Indium phosphide QDs have emerged as a primary candidate to replace the more toxic CdSe QDs, but production of

Theoretical analysis and kinetic modeling on hydrogen addition and abstraction by H radical of 1,3-cyclopentadiene and the associated chain-branching reactions [PDF]
Cyclopentadiene (CPD) is an important intermediate in the combustion of fuel and the formation of aromatics. In the present study, the kinetics and thermodynamic properties for hydrogen abstraction and addition with CPD, and the related reactions including the isomerization and decomposition on the C5H7 potential energy surface were systematically ...

Metrology and Many-Body Physics with Ultracold Metastable Helium [PDF]
Ultracold dilute gases provide ideal settings for measurements of atomic structure. Helium has an internal structure sufficiently simple to permit highly accurate predictions of its resonances and transition rates. Precise laser spectroscopy of helium thus yields empirical constraints on such calculations.

Chemical dynamics of triacetylene formation and implications to the synthesis of polyynes in Titan's atmosphere [PDF]
For the last four decades, the role of polyynes such as diacetylene (HCCCCH) and triacetylene (HCCCCCCH) in the chemical evolution of the atmosphere of Saturn's moon Titan has been a subject of vigorous research. These polyacetylenes are thought to serve
