Interaction of atomic hydrogen with monometallic Au(100), Cu(100), Pt(100) surfaces and surface of bimetallic Au@Cu(100), Au@Pt(100) overlayer systems: The role of magnetism [PDF]

open access: yesHydrogen, Fuel Cell & Energy Storage, 2018
The spin-polarized calculations in generalized gradient approximation density–functional theory (GGA–DFT) have been used to show how the existence of second metals can modify the atomic hydrogen adsorption on Au (100), Cu (100), and Pt (100) surfaces ...

Measurement of the Strong Coupling alpha s from Four-Jet Observables in e+e- Annihilation [PDF]

open access: yes, 2006
Data from e+e- annihilation into hadrons at centre-of-mass energies between 91 GeV and 209 GeV collected with the OPAL detector at LEP, are used to study the four-jet rate as a function of the Durham algorithm resolution parameter ycut. The four-jet rate

Chelex 100 as a medium for simple extraction of DNA for PCR-based typing from forensic material.

open access: yesBioTechniques, 2013
Procedures utilizing Chelex 100 chelating resin have been developed for extracting DNA from forensic-type samples for use with the PCR. The procedures are simple, rapid, involve no organic solvents and do not require multiple tube transfers for most ...
