The drops of lead dissolve the gold, silver, and platinum-group metals, then coalesce and gradually descend through the sample to form a metallic layer at the bottom of the crucible.
We can consider the metal tip and the surface of the sample to form a capacitor.
By controlling the sintering period, compositional non-uniformity was intentionally introduced into the sintered sample to form a quasi-steady state composite-like structure.
The existence of centrifugal acceleration had a significant effect on both metallurgical alloying and mechanical interlocking between different layers of the sample to form a functional material.
The caesium-137 (137Cs) technique for estimating net, time-integrated soil redistribution by the processes of wind, water and tillage is increasingly being used with repeated sampling to form a baseline to evaluate change over small (years to decades) timeframes.
The single ZnO nanowire was excited with a 488-nm Ar ion laser with 5 mW laser power on the sample, to form a spot size of ~0.3 μm in diameter.
For example, a 50 pA probe, with a beam semi-convergence angle of 25 mrad that is focused 100 Å deep into the sample to form a spot of 1Å diameter, would spread over an area of ~20 Å2 at the crystal surface.
The CuO nanowire was excited by focusing a 514.5-nm 514.5-nmArer (Coherent ion., Santa Claser Coherent wInc.a 5-mW laSanta Clara, CAe sample to form a spot size of approximately 1 μm in diameter, giving a power density of 102 W/cm2.
We pooled the CHB and JPT samples to form a single sample.
Under this hypothesis, we expected urban samples to form a monophyletic group separate from those derived from natural populations.
