For validating the current evaluated neutron data libraries, neutron leakage spectra from lead and lead bismuth eutectic (LBE) cylinders have been measured using an intense D-T pulsed neutron source with time-of-flight (TOF) method by Institute of Nuclear Energy Safety Technology (INEST), Chinese Academy of Sciences (…
The present work indicated that ligand-exchanged metal–organic frameworks could behave as superlenses in air to resolve 100 nm under a conventional white-light microscope, obtaining a super-resolution of λ /6.
Implantes inclinados atualmente são utilizados como uma alternativa cirúrgica e protética. Por tanto, estudos in vitro demonstram que o seu uso aumenta a concentração de tensão no osso cortical peri-implantar e questionase se esse fator pode levar ao insucesso da reabilitação oral estética. O objetivo do presente arti…
Sugarcane bagasse cellulose (SBC) was dissolved in three imidazolium-based ionic liquids (ILs) [Emim]DEP, [Emim]Ac and [Bmim]Cl at the same conditions (1% mass loading, 110). Among the three ILs, [Emim]DEP has the highest dissolution rate and regeneration yield of SBC. Both the original and regenerated SBC samples wer…
KSTAR is a medium size fully superconducting tokamak. The deuterium-deuterium (D-D) reaction in the KSTAR tokamak generates neutrons with a peak yield of 3.5x1016 per second through a pulse operation of 100 seconds. The effect of neutron generation from full D-D high power KSTAR operation mode to the machine, such as…
A highly selective filter is designed, working at 1.55 μm and having a 3-dB bandwidth narrower than 0.4 nm, as is required in Dense Wavelength Division Multiplexed systems. Different solutions are proposed, involving photonic crystals made rectangular- or circular-section dielectric rods, or else of holes drilled in a…

In the atypical context of Antarctica to the correct selection of more sustainable and efficient materials, it must be considered the specific environmental conditions of the region. Among them, there are the climatic characteristics (low absolute moisture content, low temperatures, high wind speeds, and rapid climate…
In this work, the radiation shielding analysis for a RTPV (Radioisotope Thermo-Photo-Voltaic) device using 238PuO2 was performed to estimate the radiation dose distribution over source region and radiation doses in a specified tally zone. The radiation source intensities and spectra were evaluated with ORIGEN-S and th…
We present results of the study aimed at assessing the effect of duty cycle (D) during plasma electrolytic oxidation (PEO) on protective properties of the coatings produced on 5754 aluminum alloy. It is shown that increasing the duty cycle of a microsecond current pulses leads to increased hardness and reduced abrasiv…
Due to the inherent hydrophobic nature of Polyester fibers, fabrics formed entirely from Polyester fibers exhibit relatively poor moisture absorption and release properties introduce an uncomfortable condition to the wearer. The present study focuses on adding enhanced and durable hydrophobicity properties to Polyeste…
The investigation of prompt γ-ray emission in nuclear fission has a great relevance for the assessment of prompt heat generation in a reactor core and for the better understanding of the de-excitation mechanism of fission fragments. Some years ago experimental data was scarce and available only from a few fission reac…
本文分析了几种典型沟槽形状的金属纳米光栅(MNG)的光波传播特性。利用多重多级子程序法(MMP)计算了光栅形状和入射光波长对反射率和透射率的影响。结果显示，金属纳米光栅存在表面等离子体共振(SPR)和局域化表面等离子体共振(LSPR)两种共振模式。LSPR共振波长强烈依赖于光栅的沟槽形状、槽深、槽宽等结构参数，呈现宽带光谱响应机制，而SPR更多的依赖于光栅周期大小，呈现窄带光谱响应机制。两种共振模式的不同特性拓展了我们对金属纳米光栅的光学传播特性的认识，这对根据需要合理设计金属纳米光栅有重要的指导意义。 Optical propagation properties of metallic nano-gratings (MNG) w…
The first studies of critical phenomena date back to the second half of the nineteenth century and resulted in the first half of the twentieth century in the comprehensive picture of the so called mean-field theory. As more precise experimental techniques were developed it became apparent in the middle of the last cen…
Enclosure is an important equipment to reduce the electromagnetic interference. Rational design can make electronic equipment has a good electromagnetic compatibility. This paper presents the coupling elements of the typical electronic information equipment, then uses the HFSS scripting language (VB script) to build a…
Goal of the present work is the dose distribution of biological material by X-ray and -photon at 0.015 to 15 MeV up to penetration depth 40 MFP. The mass attenuation coefficient, effective atomic number (Zeff), effective electron density (Neff) were calculated at 1 keV to 100 GeV and energy absorption build-up factor…
The presence of calcium oxalate (CaOx) hydrate crystals, which have low solubility in water, is widespread in nature. These crystals cause undesirable effects in certain aspects of human life, and many of these problems are still unsolved due to the lack of necessary information about the crystallization and dissoluti…
The article provides the study results of cleaning oil-well tubes, the oil-well tube failure reasons for service by their types have been considered. The chemical method of cleaning oil-well tubes as the least expensive has been reviewed when acid solution moves to the interptube space mixing up with oil and liquidate…
Composites of bio-based aliphatic polyfunctional epoxy resin reinforced with high concentration of bio-silica were prepared by a solvent free method. The unmodified bio-silica (BS) was obtained from rice husk. Two amine hardeners were used: one was based on polyethylene oxide (PEO) and the other on polypropylene oxide…
Using the coherent potential approximation, we investigate the effects of disorder on the optical absorption and the density of states of Frenkel exciton systems on square, rectangular, and triangular lattices with nearest-neighbor interactions and a Gaussian distribution of transition energies. The analysis is based…
