NMR characterization of chlorhexidine in lipid-based formulations /
(Brock University, 2004-07-14)
A mixture of Chlorhexidine digluconate (CHG) with glycerophospholipid 1,2-dimyristoyl-
<^54-glycero-3-phospocholine (DMPC-rf54) was analysed using ^H nuclear magnetic resonance.
To analyze powder spectra, the de-Pake-ing ...
Transmission measurements using a new far-infrared set-up
(Brock University, 1996-07-09)
A system comprised of a Martin-Puplett type polarizing interferometer and a Helium-3
cryostat was developed to study the transmission of materials in the very-far-infrared
region of the spectrum. This region is of ...
Preparation of SrMgx-Ru1-xO3 thin films by pulsed laser deposition /
(Brock University, 2004-07-14)
SrMg^Rui-iOa thin films were made by using pulsed laser deposition on
SrTiOa (100) substrates in either O2 or Ar atmosphere. The thin films
were characterized by x-ray diffraction, energy dispersive x-ray microanalysis,
dc ...
Pressure dependence of superconducting properties of MgB2 /
(Brock University, 2003-07-14)
We prepared samples of MgB2 and ran sets of experiments aimed for investigation of
superconducting properties under pressure. We found the value of pressure derivative
of the transition temperature -1.2 ± 0.05 K/GPa. ...
X-ray diffraction from Al powder using energy dispersive technique
(Brock University, 1991-07-09)
Using the energy dispersive x ...ray diffraction (EDXD)
technique, the room temperature diffraction pattern of Al powder was
obtained at diffraction angles ~ 30° and 50°. From the small angle
diffraction pattern the ...
Ultrasonic attenuation in layered superconductors /
(Brock University, 2006-06-04)
We study the ultrasonic attenuation in layered superconductors using the Green's function
formalism. General expressions are derived analytically and then calculated numerically
by taking the nearest and next-nearest ...
Optical properties of organic superconductor K-(BETS)2FeBr4 /
(Brock University, 2007-06-09)
K-(BETS)2FeBr4 is a quasi-2D charge transfer organic metal with interesting electronic and magnetic
properties. It undergoes a transition to an antiferromagnetic (AF) state at ambient pressure at the
Neel temperature ...
Coriolis effects in symmetric top spectra /
(Brock University, 1974-06-09)
The "x-y Coriolis Coupling Theory" as presented by Dilauro and
Mills (1966) is reformulated and extended to the determination of
Raman intensities. Theoretical Raman and Infrared spectra are
computed in order to understand ...
Far infrared reflectance and optical properties of organic superconductor (TMTSF)2ClO4 /
(Brock University, 2001-05-21)
Polarized reflectance measurements of the quasi I-D charge-transfer salt (TMTSFh CI04
were carried out using a Martin-Puplett-type polarizing interferometer and a 3He refrigerator
cryostat, at several temperatures between ...
Far infrared optical properties of V and Cr doped Sb2Te3 /
(Brock University, 2009-06-15)
The far infrared reflectance of Sb2Te3 , Sbi.97Vo.o3Te3 and Sbi.94Cr .o6Te3 was measured near
normal incidence at different temperatures (between 45K and 300K). The direct current
resistivities of the above samples were ...
