Cell viability in natural phytoplankton communities quantified by a membrane permeability probe
Cell viability natural phytoplankton communities quantified membrane permeability probe
2014/5/27
A nonstaining method, based on the digestion of dead cells, the membranes of which are permeable when exposed to an enzymatic cocktail (DNAse I and Trypsin), was used to identify living cells in cultu...
Rapid Sex Identification of Chicken by Fluorescence In Situ Hybridization Using a W Chromosome-specific DNA Probe
Chicken W Chromosome XhoI family PCR FISH Sexing
2016/4/12
It has been known that the sex of chicken cells can be most accurately identified by fluorescence in situ hybridization (FISH). However, the presently available FISH has not been widely used for sex i...
Coherent Control Experiments as a Probe of the Carrier Scattering Processes
Carrier Scattering Processes coherent control experiments
2010/4/16
We report on coherent control experiments of excitons in GaAs/AlGaAs Quantum wells.This technique, which relies on the linear response of the crystal,is used to investigate the spin-dependent exciton-...
Paramagnetic Fe3+: A Sensitive Probe for Disorder in Kaolinite
Disorder Electron Paramagnetic Resonance (EPR) Fe3+ Irradiation Kaolinite Point Defect
2011/12/22
Abstract: The Fe3+ substituted for Al3+ at the 2 octahedral positions is one of the most common impurities in the kaolinite structure detected by electron paramagnetic resonance (EPR). Evidence has be...
A New Probe Head Design for the Weak Field Double Resonance Spectrometer
Probe Head Design Weak Field Double Resonance Spectrometer
2010/4/19
In order to observe low field s EPR spectra of free radicals a new probe head was designed to work at 1.53 mT. As a double resonance spectrometer, at 1.53 mT the probe head includes both NMR and EPR r...
Detecting wave packet motion in pump–probe experiments: Theoretical analysis
Detecting wave packet motion pump–probe experiments Theoretical analysis
2014/9/24
The Zewail–Bersohn model@Ber. Bunsenges. Phys. Chem.92, 373 ~1988!# of pump–probe experiments is generalized to nonstationary wave packets and more realistic forms of probe pulses. The analysis illust...
Mobility of Small Molecules in Interlayers of Hectorite Gels: ESR Study with an Uncharged Spin Probe
ESR Hectorite Molecular mobility
2011/12/29
Electron spin resonance (ESR) spectroscopy was used to measure the rotational mobility of an uncharged nitroxide spin probe (4-hydroxy-2,2,6,6-tetramethyl-piperidinyloxy) in hectorite gels of variable...
Vibrational Probe Studies of Water Interactions with Montmorillonite
Cation exchange Desorption isotherm FTIR Gravimetric Montmorillonite Physisorption • Water
2011/12/31
Interaction of water with montmorillonite exchanged with Na+, K+, Co2+, and Cu2+ cations as a function of water content was examined using an FTIR/gravimetric cell designed to collect spectroscopic an...
Organic Anion Adsorption on Aluminum Hydroxides: Spin Probe Studies
Adsorption Aluminum hydroxide Boehmite Carboxylate Electron spin resonance Gibbsite Organophosphate
2012/2/8
The nature of organo-phosphate and carboxylate bonding in aqueous suspensions of noncrystalline alumina, boehmite, and gibbsite has been studied using the anionic nitroxide spin probes 3-carboxy-2,2,5...
The Conversion of X-Ray Intensity Ratios to Composition Ratios in the Electron Probe Analysis of Small Particles Using Mineral Standards
Albite Biotite Illite Kaolinite Orthoclase Phlogopite
2012/2/10
X-ray intensity ratios of Si/Al, Si/Fe, and Al/Fe in micron-sized particles of geochemical standards were found to vary linearly with the composition ratio. The same linear relationship was found for ...
