Activation and stabilization of gallium arsenide anode in an aqueous photoelectrochemical cell
(
Elsevier B.V.
, 2003 , Article)
The formation of a porous layer on the surface of gallium arsenide anode, n-GaAs, increases photogenerated currents significantly. This layer was formed as a result of an anodic polarization of illuminated n-GaAs in acidified ...
Photocatalytic degradation of methyl orange as a model compound
(
Elsevier
, 2002 , Article)
Titanium dioxide (TiO2) was used as a photocatalyst for the detoxification of water containing methyl orange (MO), which was used as a model compound. Solar radiation was used as an irradiation source. It was found that ...
On reality and asymptotics of zeros of q-Hankel transforms
(
Elsevier Inc.
, 2008 , Article)
We give sufficient conditions which guarantee that the finite q-Hankel transforms have only real zeros which satisfy some asymptotic relations. The study is carried out using two different techniques. The first is by a use ...
An adaptive allocation sampling design for which the conventional stratified estimator is an appropriate estimator
(
Elsevier B.V.
, 2009 , Article)
Adaptive allocations in stratified sampling design are suitable for studying Biological and Environmental populations. Biologists tend to use the conventional stratified estimator for an adaptive allocation sampling design ...
