However, moving internal moisture to the surface needs rather a long time, as a rule. The major research aim of the authors was to decrease the processing time ... [Rev. Sci.

Yon<br/> It is of practical importance to lead laboratory-scale experiments allowing a better understanding of the impact of commercial fuels composition on the formation of combustion residues such as soot particles. To this end, a hybrid burner has been designed recently to burn high-speed sprays of small ... [Rev. Sci.

Veryaskin<br/> Magnetic gradiometers are tools for geophysical exploration. The magnetic gradient is normally calculated by subtracting the outputs of two total field magnetometers which are separated by a baseline. Here we present a unique device that directly measures magnetic gradients using only a single strin ... [Rev. Sci.

Nolte<br/> Spinning biodisks have advantages that make them attractive for specialized biochip applications. The two main classes of spinning biodisks are microfluidic disks and bio-optical compact disks (BioCD). Microfluidic biodisks take advantage of noninertial pumping for lab-on-a-chip devices using nonine ... [Rev. Sci.

Wilen<br/> The structure and evolution of grain boundaries underlies the nature of polycrystalline materials. Here we describe an experimental apparatus and light reflection technique for measuring disorder at grain boundaries in optically clear material, in thermodynamic equilibrium. The approach is demonstra ... [Rev. Sci. Instrum. 80, 103903 (2009)] published Mon Oct 26, 2009. http://link.aip.org/link/?RSI/80/103506/1&agg=rss B. Rubin, J. L. Topper, C. C. Farnell, and A. P. Yalin<br/> We present a quartz crystal microbalance-based system for high sensitivity differential sputter yield measurements of different target materials due to ion bombardment. The differential sputter yields can be integrated to find total yields. Possible ion beam conditions include ion energies in the ra ... [Rev. Sci.

McComas et al.<br/> Electrostatic analyzers (ESA) have been used extensively for the characterization of plasmas in a variety of space environments. They vary in shape, geometry, and size and are adapted to the specific particle population to be measured and the configuration of the spacecraft. Their main function is t ... [Rev. Sci.
