Green synthesis of CuNb2O6 thin film using allium cepa as catalyst
TL;DR: In this paper , a green synthesis of copper niobate (CuNb2O6) thin film using copper (II) sulfate pentahydrate (CuSO4 · 5H2O), an organometallic precursor of bis(cyclopentadienyl) niobium (IV) dichloride (C10H10Cl2Nb), using Allium cepa as a catalyst.

Generalized Gradient Approximation Made Simple
TL;DR: A simple derivation of a simple GGA is presented, in which all parameters (other than those in LSD) are fundamental constants, and only general features of the detailed construction underlying the Perdew-Wang 1991 (PW91) GGA are invoked.

Electrochemical Photolysis of Water at a Semiconductor Electrode
Akira Fujishima,Kenichi Honda +1 more
TL;DR: Water photolysis is investigated by exploiting the fact that water is transparent to visible light and cannot be decomposed directly, but only by radiation with wavelengths shorter than 190 nm.
Journal ArticleDOI
Soft self-consistent pseudopotentials in a generalized eigenvalue formalism.
TL;DR: Novel features are that the pseudopotential itself becomes charge-state dependent, the usual norm-conservation constraint does not apply, and a generalized eigenproblem is introduced.
Journal ArticleDOI
Environmental Applications of Semiconductor Photocatalysis
TL;DR: The slow pace of hazardous waste remediation at military installations around the world is causing a serious delay in conversion of many of these facilities to civilian uses as discussed by the authors, which is a serious problem.
Journal ArticleDOI
EXPGUI, a graphical user interface for GSAS
TL;DR: A description and justification of the EXPGUI program, which implements a graphical user interface and shell for the GSAS single-crystal and Rietveld package using the Tcl/Tk scripting language, is presented.
