The objective for this study was to compare light-scattering based turbidity measurements on commercial lipid microbubbles, with alternative, and indeed, complementary methods for quantifying microbubble population dynamics such as flow based cytometric techniques. Microbubble populations were seen to respond to ultra…
Some expansion joints bellows used in buried gas pipeline in east China cities cracked after 1∼2 years service, the cracks usually located at top of the bellows, they expand nearly 48% of total circumference and the whole thickness. The material of the bellows was austenitic stainless steel plate. In order to research…
Stress Corrosion Cracking (SCC) is one of the major concerns for aged nuclear reactors. SCC-susceptible materials have been employed in a wide variety of applications in the nuclear industry. Laser Peening (LP) is a method for the SCC mitigation that eliminates surface tensile stress using impulsive effect of high-pre…
We demonstrate nanoparticle manipulation using surface plasmons. We fabricate optical antennas for SERS, with gaps down to 3 nm. We demonstrate that silicon nanowires take on a surprising variety of colors covering the visible spectrum.
Optical spectra, excited state relaxation dynamics and thermal conductivity in a wide temperature region for thulium-doped YVO4, GdVO4 and LuVO4 have been measured and analyzed to assess thermal effects in laser-diode-pumped Tm:vanadate lasers.
Ni-Cu-Zn ferrites with general formula Ni0.5Zn0.5-x/2Cux/2Fe2O4 (with x = 0.3, 0.4, 0.5 and 0.6) have been synthesized using oxalate precursor method with different precursor reaction temperatures in the range 10℃ to 70℃. The Curie temperatures obtained using AC susceptibility measurements are found to be in the range…
The experimental nuclear power reactor based on the fusion principle, tested in the framework of the international project ITER, will be installed in France. In Europe, all pressure equipments must comply with the Pressure Equipment Directive 97/23/CE (PED) and satisfy the Essential Safety Requirements (ESRs) set out…
In the medical field, the active ingredient is in the form of solid particles for 90% of all medicines. Because of development in nanotechnology, it is now possible to produce drug nanoparticles that can be utilised in a variety of innovative ways according to the need. From few decades, there had been considerable in…
ASME published Code Case 2564 [1] in January 2008 on impulsively loaded vessels, which is currently the first design guidance of this kind worldwide. The authors participated in the Task Group on Impulsively Loaded Vessels reporting to Sec. VIII, Div. 3 [2] and were also intimately engaged in the development, design a…
The mechanical behaviors of epoxy-based shape memory polymer (SMP) with linear monomer at the temperatures of 25oC, 42oC, 56oC and 66oC are respectively investigated through the tension tests. Material parameter equations are supposed to describe the relationships between the material parameters of SMP with linear mon…
Monte Carlo simulations are carried out on a thin planar film of nematic liquid crystal, subjected to specific textured anchoring conditions, so as to generate azimuthal (in‐plane) bistability, as was recently reported experimentally. We investigated the switching characteristics of this system between the two directo…
We examine the development of the project for manufacturing a Russian nanolithographer with an operating wavelength of λ = 13.5 nm for fabricating nanoelectronic element bases (chips) according to technological standards of 32–22 nm at the first stage and 22–16 nm at the second. A list of the project’s main participan…
The impact of a ogive‐nosed steel projectile into thick sandstone and steel targets has been simulated over impact velocities from 200 m/s to 750 m/s, and the projectile deceleration histories compared. Both targets have an entrance phase in which deceleration increases sharply. This phase is followed in a steel targe…
Microstructures of a nickel/austenitic-steel (AISI304) interface, which has been bonded through in-situ cold-rolling of clean surfaces (pre-sputtered by argon ion) within a vacuum apparatus (~10–3 Pa), then followed by an annealing at 500°C, are investigated by transmission electron microscopy. We frequently find sign…
Water management is very important in the development of the PEFC with high performance and high reliability. We found that the moisturizing effect in the straight-type channel is marked as compared with the serpentine-type channels, and the draining performance in the serpentine-type channel is better than that in th…
The thermo-mechanical simulation model applied in this study connects the temperature profile in the stringribbon furnace with parameters describing the material quality, i.e. flatness, the remaining stress, and the dislocation density of a ribbon. The essential effects of the ribbon thickness profile as well as of th…
We studied the effect of carrier concentration in p-GaN substrate on the performance of p-GaN/n-ZnO nanorod heterojunction LEDs. ZnO nanorods were electrodeposited on commercial p-GaN wafers in a two electrode system from aqueous solutions of zinc nitrate and hexamethylenetetramine. The morphology and optical properti…
Analysis of thermodynamic and thermal-engineering parameters of GTE for mercantile and naval marines was conducted. A conclusion was made that GTEs designed specially for application under sea conditions have the highest efficiency. This is the 36–37% efficiency for simple cycle GTEs. With application of the complex c…
Nickel oxide (NiO) thin films have been deposited by dc reactive magnetron sputtering technique on glass substrates at various substrate temperatures in the range of 303 to 723 K. The influence of substrate temperature on structural, morphological, compositional and optical properties was analyzed by X‐ray diffraction…
The nitrogen-vacancy (NV) color center in diamond shows great promise as an optically addressable solid-state qubit amenable to many quantum-optics applications. Using the NV center, we have demonstrated spin-photon entanglement and manipulation of nuclear spins through coherent population trapping.
