Design of N-Coordinated Dual-Metal Sites: A Stable and Active Pt-Free Catalyst for Acidic Oxygen Reduction Reaction.

Journal of the American Chemical Society, 2017
We develop a host-guest strategy to construct an electrocatalyst with Fe-Co dual sites embedded on N-doped porous carbon and demonstrate its activity for oxygen reduction reaction in acidic electrolyte.

Defect‐Rich MoS2 Ultrathin Nanosheets with Additional Active Edge Sites for Enhanced Electrocatalytic Hydrogen Evolution

Advances in Materials, 2013
Defect-rich MoS2 ultrathin nanosheets are synthesized on a gram scale for electrocatalytic hydrogen evolution. The novel defect-rich structure introduces additional active edge sites into the MoS2 ultrathin nanosheets, which significantly improves their ...

Single Cobalt Atoms Anchored on Porous N-Doped Graphene with Dual Reaction Sites for Efficient Fenton-like Catalysis.

Journal of the American Chemical Society, 2018
The Fenton-like process presents one of the most promising strategies to generate reactive oxygen-containing radicals to deal with the ever-growing environmental pollution.

Coordinatively unsaturated metal sites (open metal sites) in metal-organic frameworks: design and applications.

Chemical Society Reviews, 2020
Metal-organic frameworks (MOFs) can contain open metal sites (OMS) or coordinatively unsaturated sites (CUS) or open coordination sites (OCS) when vacant Lewis acid sites on the metal ions or cluster nodes have been generated.

LCOGT sites and site operations

SPIE Proceedings, 2010
LCOGT is currently building and deploying a world-wide network of at least twelve 1-meter and twenty-four 0.4-meter telescopes to as many as 4 sites in the Southern hemisphere (Chile, South Africa, Eastern Australia) and 4 in the Northern hemisphere (Hawaii, West Texas, Canary Islands).

Site−Site Potentials in Neopentane and Tetramethylsilane

The Journal of Physical Chemistry A, 2005
Neopentane and TMS are used as model M(CH(3))(4) systems to investigate intramolecular interactions. The nonbonded site-site potential between two proximal hydrogen atoms on different methyl groups, V(nb)(d(HH)), is not Lennard-Jones- or Morse-like but is found to be pseudolinear in hydrogen-hydrogen internuclear separation, d(HH), for both neopentane ...

Site Characterization

2017
A necessary first step in qualifying a specific site for CO2 storage and for quantifying its relevant properties is a proper site characterization.
