Quick quantification of proteins by MALDI

18.02.2015 | Sung Hee Ahn, Jeong Won Kang, Jeong Hee Moon, Kwang Pyo Kim, Seong Hoon Lee, Myung Soo Kim, Journal of Mass Spectrometry, 2015

Previously, we reported that the matrix‐assisted laser desorption ionization spectrum of a peptide became reproducible when an effective temperature was held constant. Using a calibration curve drawn by plotting the peptide‐to‐matrix ion abundance ratio versus the peptide concentration in a ...

Large‐scale plant growth chamber design for elevated pCO2 and δ13C studies

28.01.2015 | William M. Hagopian, Brian A. Schubert, A. Hope Jahren, Rapid Communications in Mass Spectrometry, 2015

Rationale Throughout at least the next century, CO2 fertilization and environmental stresses (e.g. nutrient, moisture, insect herbivory) are predicted to affect yields of economically important crop species. Stable isotopes of carbon are used to study plant stresses, which affect yields, but a ...

Effect of N2 on emission profile and excitation temperature in axially viewed plasma-ICP OES

30.12.2014 | Dirce Pozebon; Guilherme Luiz Scheffler, Journal of Analytical Atomic Spectrometry, 2014

Fundamental studies were conducted in order to gain useful insights about energy transfer that takes place when a low flow (20 mL min-1) of N2 is introduced into the central channel of the Ar-ICP source in inductively coupled plasma optical emission spectrometry (ICP OES). Axial and radial ...

Use of an ionic liquid‐based surfactant as pseudostationary phase in the analysis of carbamates by micellar electrokinetic chromatography

27.12.2014 | Carmen Tejada‐Casado, David Moreno‐González, Ana M. García‐Campaña, Monsalud del Olmo‐Iruela, ELECTROPHORESIS, 2014

The applicability of an ionic liquid based cationic surfactant 1‐dodecyl‐3‐methylimidazolium tetrafluoroborate (C12MImBF4) as pseudostationary phase in micellar electrokinetic chromatography (MEKC) has been evaluated for the analysis of eleven carbamate pesticides (promecarb, carbofuran, ...

Simultaneous determination of herbicides residues in tobacco using ultra performance convergence chromatography coupled with solid‐phase extraction

27.12.2014 | Weiyun Guo, Zhaoyang Bian, Daohong Zhang, Gangling Tang, Wei Liu, Jianlong Wang, Zhonghao Li, Fei Yang, Journal of Separation Science, 2014

A time‐saving and organic‐solvent‐efficient method to simultaneously determine six kinds of herbicide residues in tobacco using solid‐phase extraction for sample clean‐up and pre‐concentration and the highly sensitive ultra performance convergence chromatography method was developed. Parameters ...

Cooling dynamics of self‐assembled monolayer coating for integrated gold nanocrystals on a glass substrate

26.12.2014 | Kouhei Ichiyanagi, Hiroshi Sekiguchi, Tokushi Sato, Shunsuke Nozawa, Ayana Tomita, Manabu Hoshino, Shin‐ichi Adachi, ..., Journal of Synchrotron Radiation, 2014

Picosecond time‐resolved X‐ray diffraction has been used to study the nanoscale thermal transportation dynamics of bare gold nanocrystals and thiol‐based self‐assembled monolayer (SAM)‐coated integrated gold nanocrystals on a SiO2 glass substrate. A temporal lattice expansion of 0.30–0.33% was ...

Inelastic X‐ray scattering with 0.75 meV resolution at 25.7 keV using a temperature‐gradient analyzer

26.12.2014 | Daisuke Ishikawa, David S. Ellis, Hiroshi Uchiyama, Alfred Q. R. Baron, Journal of Synchrotron Radiation, 2014

The use of temperature‐gradient analyzers for non‐resonant high‐resolution inelastic X‐ray scattering is investigated. The gradient compensates for geometrical broadening of the energy resolution by adjusting the lattice spacing of the analyzer crystal. Applying a ∼12 mK temperature gradient ...

Design and development of a controlled pressure/temperature set‐up for in situ studies of solid–gas processes and reactions in a synchrotron X‐ray powder diffraction station

26.12.2014 | Eduardo Salas‐Colera, Álvaro Muñoz‐Noval, Catherine Heyman, Conchi O. Ania, José B. Parra, Santiago García‐Granda, S ..., Journal of Synchrotron Radiation, 2014

A novel set‐up has been designed and used for synchrotron radiation X‐ray high‐resolution powder diffraction (SR‐HRPD) in transmission geometry (spinning capillary) for in situ solid–gas reactions and processes in an isobaric and isothermal environment. The pressure and temperature of the sample ...

Sensors, Vol. 15, Pages 304-330: An Efficient Approach for Pixel Decomposition to Increase the Spatial Resolution of Land Surface Temperature Images from MODIS Thermal Infrared Band Data

25.12.2014 | Wang, Fei ; Qin, Zhihao ; Li, Wenjuan ; Song, Caiying ; Karnieli, Arnon ; Zhao, Shuhe, Sensors, 2014

Land surface temperature (LST) images retrieved from the thermal infrared (TIR) band data of Moderate Resolution Imaging Spectroradiometer (MODIS) have much lower spatial resolution than the MODIS visible and near-infrared (VNIR) band data. The coarse pixel scale of MODIS LST images (1000 m under ...
