Problem statement: Rolling element bearings form a very important part of machinery. The increasing demands on their continuous reliable operation under diverse environments make maintenance a very important step towards the efficient use of them. To this end, precision maintenance is a very useful practice, since it…
Abstract: Problem statement: At present the term ‘nanotechnology ’ is well known-in its ’ ideal form, the flawless and completely controlled design of conventional molecular matter from molecules or atoms. Such a power over nature would offer routine achievement of remarkable properties in conventional matter and crea…
This paper describes the procedure that has been optimized for the determination of dopamine at Lamotrigine modified carbon paste electrode (LTGMCPE) by cyclic voltammetry with 0.2M phosphate buffer at pH 7. The carbon paste electrode (CPE) was modified by Lamotrigine and Triton-X-100 (TX-100).The LTGMCPE and TX-100 i…
Surface plasmon effects excitation from the three-pair arrays of silver-shell nanocylinders are investigated numerically by using the finite-element method. Effects from different illumination wavelengths, interparticle distance, interpair distance, and the radii of air hole in nanocylinders are studied. Compared to t…
Effects of oil brand, temperature and atmosphere conditions on copper sulfide deposition on insulating paper were investigated by thermal aging test. Copper sulfide deposition occurred in a certain oil brand and dibenzyl disulfide (DBDS) was found in the oil. There was an incubation period observed before copper sulfi…
A series of sorption isotherms of CO2, CH4 and N2 of a metal organic framework (Cu-BTC) were measured at 0 to 15 bar and at 25 and 105 ∘C. Cu-BTC showed much higher working capacity than the benchmark zeolite 13X in pressure swing adsorption at 25 ∘C, and higher CO2/N2 and CO2/CH4 selectivities at a higher pressure ra…
The results of ab initio calculations of the structural, elastic, electronic, and phonon properties of BeO in both zinc-blende and wurtzite structures are presented. Our calculations are based on the application of plane-wave basis, pseudopotentials, and the generalized gradient approximation of the density functional…
Interconnection plays an important role in performance and power of CMP designs using deep sub-micron technology. The network-on-chip (NoCs) has been proposed as a scalable and high-bandwidth fabric for interconnect design. The advent of the 3D technology has provided further opportunity to reduce on-chip communicatio…
A bandpass, miniaturized-element frequency selective surface with relatively high out-band rejection was recently reported whose unit cell dimensions are smaller thanlambda0/10. The new FSS is made up of a metallic, square loop array and a metallic grid on either side of a thin dielectric substrate. Further analysis o…
Energy harvesters [1] power energy-autonomous wireless sensor systems by converting ambient environmental energy into electrical energy. Thermoelectric generators (TEG's) are a suitable compact power supply for both on-the-body and industrial sensors. Due to changing conditions, the generated power and voltage vary. T…
This paper presents elastic buffers (EBs), an efficient flow-control scheme that uses the storage already present in pipelined channels in place of explicit input virtual-channel buffers (VCBs). With this approach, the channels themselves act as distributed FIFO buffers. Without VCBs, and hence virtual channels (VCs),…
PURPOSE: To prospectively predict the effectiveness of a clinically used nanochemotherapeutic agent by detecting and measuring the intratumoral uptake of an x-ray contrast agent nanoprobe by using digital mammography. MATERIALS AND METHODS: All animal procedures were approved by the institutional animal care and use c…
The use of amines for CO2 capture from flue gases involves one distinct difference and challenge from traditional amine acid gas capture: the presence of dioxygen and its role in the oxidative degradation of the amine. Insights on mechanisms of degradation in flue gas CO2 capture can be obtained from observations of o…
The thermal expansion coefficients of the hexagonal SiC polytypes 4H and 6H and with Al and N dopants have been determined for temperatures between 300 and 1770 K. Further, a set of the room temperature lattice parameters in dependence on doping with N, Al, and B has been obtained. Data for the thermal expansion were…
AIMS: To determine if commercial sunscreens contain distinct nanoparticles and to evaluate analytical methods for their ability to detect and characterize nanoparticles in unmodified topical products using commercial sunscreens as a model. METHODS: A total of 20 methods were evaluated for their ability to detect and c…
An original surface passivation technique of indium tin oxide (ITO) used as anode in organic solar cells is proposed. We demonstrate that a thin MoO3 film (3.5±1 nm) at the interface ITO/organic donor allows improving significantly the devices’ performances. The devices are based on the multiheterojunction structure c…
A novel type of microstrip antenna is proposed for compact wideband wireless applications. The antenna is composed of six unit cells of left-handed metamaterial (LHM) and a dipole element. The dipole is directly connected to three of six LHM unit cells, which are arranged in a 2 times 3 antenna array form. In this asp…
Bentonite is currently designated for use as a buffer material for the repository of high-level radioactive waste because such a material requires swelling characteristics to seal the waste. A high-level radioactive waste disposal facility may be built in a coastal area of Japan because transportation of this waste by…
Chemical-looping with oxygen uncoupling (CLOU) is a novel method to burn solid fuels in gas-phase oxygen without the need for an energy intensive air separation unit. This paper presents batch laboratory fluidized bed CLOU tests where six different solid fuels are used with a Cu-based oxygen carrier. The results show…
We study the behavior of self-propelled nano- and micro-rods in three dimensions, confined between two parallel walls, by simulations and scaling arguments. Our simulations include thermal fluctuations and hydrodynamic interactions, which are both relevant for the dynamical behavior at nano- to micro-meter length scal…
