Depth-dependent local structures in thin films unraveled by grazing-incidence X-ray absorption spectroscopy
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
A method of using X-ray absorption spectroscopy together with resolved grazing-incidence geometry for depth profiling of atomic, electronic or chemical local structures in thin films is presented. The quantitative deconvolution ...
Polarographic and spectrophotometric behavior of some N-para-phenyl substituted benzamidines
(INST ORGANIC CHEM AND BIOCHEM, ACAD SCI CZECH REPUBLIC, 1991-12)
Five N-p-phenyl substituted benzamidines were studied by DC and DP polarography in a wide pH range. Coulometric results show that the overall processes are four-electron reductions. Logarithmic analysis of the waves indicate ...
Induced crystallization on tellurite 20Li(2)O-80TeO(2) glass
(Iop Publishing Ltd, 2007-06-07)
Crystallization kinetics and structure of 20Li(2)O-80TeO(2) glasses are studied using x-ray diffraction, Fourier transform infrared spectroscopy and differential scanning calorimetry techniques. XRD results show gamma-TeO2, ...
Detection of DNA Nucleotides on Pretreated Boron Doped Diamond Electrodes
(Soc Brasileira Quimica, 2011-01-01)
The individual detection and equimolar mixture of DNA nucleotides guanosine monophosphate (GMP), adenosine monophosphate (AMP), thymidine (TMP) and cytidine (CMP) 5'-monophosphate using square wave voltammetry was performed ...
Photoluminescence in amorphous zirconium titanate
(Springer, 2004-02-01)
Photoluminescence at room temperature was observed in amorphous zirconium titanate obtained from the polymeric precursor method. This was the first time in which PL was noticed in an amorphous compound made of two network ...
Singular Value Decomposition and Ligand Binding Analysis
(Hindawi Publishing Corporation, 2013-01-01)
Singular values decomposition (SVD) is one of the most important computations in linear algebra because of its vast application for data analysis. It is particularly useful for resolving problems involving least-squares ...
Tetradentate schiff base copper(II) complexes
(1999-12-01)
Ten copper(II) complexes of tetradentate Schiff bases obtained by condensing two moles of an o-hydroxyphenylcarbonyl compound with a diamine have been prepared and characterized by elemental analyses, melting points, IR ...
Interval multivariate curve resolution in the dereplication of HPLC-DAD data from Jatropha gossypifolia
(2013-07-01)
Introduction Jatropha gossypifolia has been used quite extensively by traditional medicine for the treatment of several diseases in South America and Africa. This medicinal plant has therapeutic potential as a phytomedicine ...
Distributed Temperature Sensing Using Cyclic Pseudorandom Sequences
(Institute of Electrical and Electronics Engineers, 2017-03)
An alternative for commercial Raman-Optical Time Domain Reflectometry (OTDR) distributed temperature sensors is presented, where a pseudorandom pulse sequence is used to increase the signal to noise ratio. Additionally, a ...
