Accuracy of sample material parameters reconstruction using terahertz pulsed spectroscopy
, 2014New experimental and theoretical results for the material parameter reconstruction using terahertz (THz) pulsed spectroscopy (TPS) are presented. The material parameter reconstruction algorithm was realized and experimentally implemented to study the ...

Effect of Sample Preparation on Microwave Material Characterization by Loaded Waveguide Technique
IEEE Transactions on Instrumentation and Measurement, 2016Microwave material characterization is an important nondestructive evaluation tool, as many physical and chemical properties can be related to a material's dielectric properties.

Total reflection X-ray fluorescence analysis of laser-deposited solid sample material
, 2000Laser ablation (LA) was applied as a sampling technique for the analysis of solids by total reflection X-ray fluorescence (TXRF). The sample material ablated by a pulsed Nd∶YAG laser was collected directly on a quartz glass or Plexiglas® disc commonly ...

Sampling of road surfacing materials
Journal of Applied Chemistry, 1970AbstractThe meaning and purpose of sampling are discussed. Results are presented from a series of road trials on the sampling of asphalt mixtures to demonstrate the importance of bias and variability introduced into test measurements by sampling. Further variability is introduced by the reduction in size by quartering of gross samples to the size ...

Dependence of resolution on sample material in rotational Auger depth profiling
, 1994Dependence of optimum sample rotation on sample material in Auger in‐depth analysis was investigated for Al, Mo, Ag, and Ta films deposited on Si wafers, using 1 and 3 keV Ar + and Xe+ ions as projectiles.

Analytical Chemistry, 2003
Proteomics is critically dependent on optimal sample preparation. Particularly, the interface between protein digestion and mass spectrometric analysis has a large influence on the overall quality and sensitivity of the analysis. We here describe a novel

Refractory materials in comet samples
Meteoritics & Planetary Science, 2017AbstractTransmission electron microscope examination of more than 250 fragments, >1 μm from comet Wild 2 and a giant cluster interplanetary dust particle (GCP) of probable cometary origin has revealed four new calcium‐aluminum‐rich inclusions (CAIs), an amoeboid olivine aggregate (AOA), and an additional AOA or Al‐rich chondrule (ARC) object. All of

A new material of cryopreserving cell samples
Cryobiology, 2020Cryopreservation was first studied in early twentieth century, and the cryopreservation of cell and tissue samples has become an inseparable process in biology research labs, helping scientists to store living materials and to accumulate specimens.

S-Trap, an Ultrafast Sample-Preparation Approach for Shotgun Proteomics.
Journal of Proteome Research, 2018The success of shotgun proteomic analysis depends largely on how samples are prepared. Current approaches (such as those that are gel-, solution-, or filter-based), although being extensively employed in the field, are time-consuming and less effective ...
