Bismuth and antimony are semimetals with a rhombohedral crystal structure and similar lattice parameters. Bi12xSbx alloys exhibit unusual electronic properties and are of interest for thermoelectric and magnetoelectronic devices. In this paper, we show that Bi12xSbx alloys can be electrodeposited from acidic chloride-based solutions and that a homogenous solid solution is obtained across the en...

It is known that an axial piston pump barrel experiences small oscillations due to forces acting over it. Cavitation als o occurs in many cases, damaging the plate and barrel sliding surfaces and therefore reducing the volumetric and overall efficiency of the pump. More importantly, the resulting failure of the pump is often a critical issue in modern industrial applications. The complex fluctu...

This paper addresses the problem of path planning for a thin elastic metal plate under fairly general manipulation constraints. The underlying geometric model for the plate is provided by a B ezier representation. The geometric model is augmented by a realistic mechanical model. We assume that the plate is manipulated in accordance with a set of user-deened grasping constraints that specify the...

Broadband horn antennae are presented that efficiently couple terahertz radiation between sub-wavelength metal-metal waveguides and free space. Sub-picosecond terahertz pulses were coupled into and out from sub-wavelength parallel-plate waveguides by using the horn antennae in a terahertz time-domain spectrometer. Monolithic antennae were fabricated at the facets of metal-metal terahertz quantu...

Nanofluids are colloidal suspensions of nanosized particles in the conventional base fluid such as water, engine oil and ethylene glycol. The nanoparticles include the chemically stable metals, metal oxides and nonmetallic. In the present study, the literature available on the applications of nanofluids in plate heat exchanger have been compiled and reviewed. However, this paper elaborates the ...

A slit in a thick metal plate that is extremely subwavelength will not transmit microwaves polarized parallel to it. It is shown here that cuts perpendicular to the slit allow parallel polarized radiation to resonantly transmit. Furthermore, a zero-order mode may be excited within the slit, the frequency of which, to first order, is independent of the plate depth. Remarkably, for this novel typ...

Kastl, Sigrid, U. Kotschenreuther, B. Hille, J. Schmidt, H. Gepp, and W. Hohenberger. Simplification of rat intubation on inclined metal plate. Adv Physiol Educ 28: 29–32, 2004; 10.1152/advan.00008.2003.—Small-animal intubation is often necessary during inhalation anesthesia to allow steady-state conditions for large operations and in vivo experiments in all fields of experimental surgery. In r...

In an attempt to prolong the lives of rubbing implantable devices, several 'new' materials have been examined to determine their suitability as joint couplings. Tests were performed on a multidirectional pin-on-plate machine to determine the wear of both pitch and PAN (polyacrylonitrile)-based carbon fibre reinforced-polyetheretherketone (CFR-PEEK-OPTIMA) pins articulating against both BioLox D...

the effect of welding residual stresses that was created in thin infill plate of steel plate shear wall system during constructional processes was studied in this research. residual stresses in a welded structure is the result of the non-uniform expansion and contraction and plastic deformation of the weld and surrounding base metal due to heating and cooling cycle, during welding process, this...

It is shown that a simple metal plate serving as a mirror decisively improves ultrasound mammography. A suitable reconstruction algorithm is described. A numerical example based on computer simulations is given.
