Tuning Active Hydrogen on Reconstructed RuO2/Co(OH)2 Catalysts for Selective Ammonia Synthesis

Advanced Materials, EarlyView.
A combined approach of precatalyst design and electrolyte engineering is employed to develop highly active, selective, and stable catalysts for electrochemical nitrate reduction. In alkaline media, the reconstructed RuO2/Co(OH)2 catalyst demonstrates impressive performance in ammonia synthesis, rechargeable Zn‐NO3− battery, and the remediation of ...

Transient Formation of Single Layer Diamond During Friction Force Microscopy of SiC‐Supported Epitaxial Graphene

Advanced Materials Interfaces, EarlyView.
Friction force microscopy using diamond tips on epitaxial graphene supported by SiC(0001) shows a sharp friction increase. Silicon tips show similar behavior but at lower threshold forces. Atomistic simulations reveal three different friction regimes as normal pressure rises: graphene‐tip interfacial slip, graphene‐tip bonding, and a reversible ...

Performance analysis of direct N-body algorithms for astrophysical simulations on distributed systems

, 2004
We discuss the performance of direct summation codes used in the simulation of astrophysical stellar systems on highly distributed architectures. These codes compute the gravitational interaction among stars in an exact way and have an O(N^2) scaling ...

Sequence search on a supercomputer

Nucleic Acids Research, 1986
A set of programs was developed for searching nucleic acid and protein sequence data bases for sequences similar to a given sequence. The programs, written in FORTRAN 77, were optimized for vector processing on a Hitachi S810-20 supercomputer. A search of a 500-residue protein sequence against the entire PIR data base Ver.

Excitonic Anisotropy in Single‐Crystalline 2D Silver Phenylchalcogenides

Advanced Optical Materials, EarlyView.
Using a combination of ab initio theory and optical micro‐spectroscopy, in‐plane anisotropy of multiple delocalized excitons in 2D silver phenylchalcogenides (AgEPh; E = S, Se, Te) is predicted and characterized. Cryogenic reflectance micro‐spectroscopy further reveals the fine structure of excitonic bands in AgSePh.
