Sample Dimensions Influence Strength and Crystal Plasticity
Science, 2004When a crystal deforms plastically, phenomena such as dislocation storage, multiplication, motion, pinning, and nucleation occur over the submicron-to-nanometer scale.

Materialized Sample Views for Database Approximation [PDF]
22nd International Conference on Data Engineering (ICDE'06), 2006 We consider the problem of creating a sample view of a database table. A sample view is an indexed materialized view that permits efficient sampling from an arbitrary range query over the view. Such "sample views" are very useful in applications that require random samples from a database: approximate query processing, online aggregation, data mining ...

Efficient and reproducible sample preparation is a prerequisite for any robust and sensitive quantitative bottom-up proteomics workflow. Here, we performed an independent comparison between single-pot solid-phase-enhanced sample preparation (SP3), filter-

This chapter develops nested sampling into a powerful tool for the calculation of pressure-temperature phase diagrams, and demonstrates how it may be applied to single species and binary systems, including the Lennard-Jones system, a binary Lennard-Jones alloy, and an EAM model for Aluminium. A comparison to parallel tempering is also presented.

Hydrophilic materials in sample pretreatment
TrAC Trends in Analytical Chemistry, 2017Abstract Sample pretreatment is a fundamental and essential step in almost all analytical procedures, especially for the analysis of biological and environmental samples with complex matrix. In the past decades, with the development of hydrophilic interaction liquid chromatography (HILIC) in the separation of polar compounds, hydrophilic materials ...

Ultracapacitors are rapidly being adopted for use for a wide range of electrical energy storage applications. While ultracapacitors are able to deliver high rates of charge and discharge, they are limited in the amount of energy stored.

Sampling of Particulate Material
2009Particulate materials are often produced in very large quantities. In contrast, usually small quantities are used for characterization or applications. There are two reasons that small samples often give poor representation of the average quality of the bulk. One reason is the discrete nature of particles.

Sampling of biological materials for infrared spectroscopy
Analytical Biochemistry, 1964Abstract Various methods for examining the infrared spectra of proteins have been investigated using yeast alcohol dehydrogenase and ribonuclease as typical proteins. These methods include films cast from aqueous solutions, KBr disks, and agar films.

A reactive material is a material which can undergo further reaction either with itself or another material or compound under environmentally-mediated conditions. Examples of these types of reactions include polymerization, hydrolysis and oxidation. Since these reactions can occur in the workplace under ambient conditions or even on sampling media, the
