It is one of the future trends to create materials in situ by laser additive manufacturing. AlSi7Mg/nano-SiCp composites were successfully prepared selective melting our previous study. After adding 2 wt% nano-SiC particles, tensile stress and strain increased 502.94 ± 6.40 MPa 10.64 1.06%, respectively. For first time present study, we systematically studied compared wear performance corrosion...

To address several fundamental questions regarding how multiwhisker tactile stimuli are integrated and processed by the trigeminal somatosensory system, a novel behavioral task was developed that required rats to discriminate the width of either a wide or narrow aperture using only their large mystacial vibrissae. Rats quickly acquired this task and could accurately discriminate between apertur...

High-quality ultra-long alloyed CdS(x)Se(1)(-)(x) (0 < or = x < or = 1) whiskers were obtained by a simple thermal evaporation route. The near band-edge emission in these whiskers can be effectively guided at the sub-millimeter scale under continuous-wave laser excitation. As good optical waveguide cavities, the whiskers exhibit stimulated emissions under pulsed light excitation at room tempera...

A novel, one-pot technique of synthesizing calcium phosphate whiskers was developed. Commercially available b-tricalcium phosphate (b-Ca3(PO4)2) powders were aged in unstirred 30% H2O2 solutions at 901C for 48 h in ordinary glass media bottles. Resultant samples consisted of whiskers (200 nm wide and 5 lmlong) of a biphasic mixture of octacalcium phosphate (OCP: Ca8H2(PO4)6 . 5H2O) and carbonat...

Male Wistar rats were exposed to two types of magnesium sulphate whiskers by inhalation for six hours a day, five days a week, for four weeks (sub-chronic study), or for one year (chronic study) to clarify the biological effects of the whiskers. There were few whiskers detected in the rat lungs even at one day after the exposure, suggesting that they are dissolved and eliminated rapidly from th...

A new panel-level silicon carbide (SiC) metal oxide semiconductor field effect transistor (MOSFET) power module was developed by using the fan-out and embedded chip technologies. To achieve more effective thermal management higher reliability under cycling, a optimization method called Ant colony optimization-back propagation neural network (ACO-BPNN) for optimizing SiC modules, contrast it wit...

Quantitative insights into the stress-transfer mechanisms that determine the mechanical properties of tunicate cellulose whisker/poly(vinyl acetate) nanocomposites were gained by Raman spectroscopy. The extent of stress-transfer is influenced by local orientation (or anisotropy) of the whiskers, which in turn is governed by the processing conditions used to fabricate the nanocomposites. Solutio...

This thesis examines the packaging of high-temperature SiC power electronic devices. Current-voltage measurements were conducted on as-received and packaged SiC power devices. The planar structure was introduced and developed as a substitution for traditional wire-bonding vertical structure. The planar structure was applied to a high temperature (>250C) SiC power device. Based on the current-vo...
