Calculated optical properties of GaX (X=P, As, Sb) under hydrostatic pressure
(Springer-Verlag, 2011)
The hydrostatic pressure dependence of the principal energy gaps and of the optical properties of GaX (X = P, As and Sb) has been calculated using the full potential-linearized augmented plane wave (FP-LAPW) method. The ...
Investigated optical and elastic properties of Porous silicon: Theoretical study
(Elsevier Ltd., 2011-08)
Compatibility between experimental and theoretical works is achieved. Empirical Pseudopotential Method (EPM) is used to calculate the energy gap of Si which is found to be indirect. Features such as refractive index, optical ...
Characterisation of calcium carbonate and its polymorphs from cockle shells (Anadara granosa)
(Elsevier B.V., 2011-11-10)
Calcium carbonate and its polymorphs from cockle shells (Anadara granosa) and commercial calcium carbonate were characterised using a variable pressure scanning electron microscopes (VPSEM), a transmission electron microscope ...
Nanoparticle sensor for label free detection of swine DNA in mixed biological samples
(IOP Publishing Ltd., 2011-05-13)
We used 40 5nm gold nanoparticles (GNPs) as colorimetric sensor to visually detect swine-specific conserved sequence and nucleotide mismatch in PCR-amplified and non-amplified mitochondrial DNA mixtures to authenticate ...
Low cost diffuser based micropump using pinch actuation
(Scientific.net, 2011-12)
Planar pinch micropump with the integration of two diffuser valve elements has been reported. The fabrication of the micropump is carried out by utilizing simple hot embossing technique for microdiffuser imprinting and ...
