Aiming at verifying the performance of the designed anti-explosion shell of primary explosive powder transport device, the explosion load of the shell was simulated by using DYNA software. Under the condition of without filling medium, the explosion load of Pb(N3)2was simulated whose mass are 211 g and 250 g respectiv…
Abstract The ability to non-invasively locate and quantify tumor cell number at a metastatic site would be of considerable interest in pre-clinical and clinical metastasis research. To this end, our objective is to develop positive-contrast cellular magnetic resonance imaging (MRI) for use in quantifying tumor cell nu…
Accidents at fixed nuclear reactor facilities present a major challenge to first responders and emergency management agencies seeking to mitigate potential health impacts, economic losses, and environmental damage. Emergency response plans must be well-coordinated, crafted in accord with international standards, and g…
The Journal of Micro/Nanopatterning, Materials, and Metrology (JM3) publishes peer-reviewed papers on the core enabling technologies that address the patterning needs of the electronics industry.
We recently developed an approach to the estimation of the complex permittivity () and thickness (d) of very thin layers using measurements of their transmittance, front-side reflectance and back-side reflectance. The approach is based on a limited expansion of the Abeles characteristic matrix elements and is especial…
A model for estimating the number of electrons produced as a result of the fast-ion-surface interaction is proposed. The dependence of the number of electrons emitted by the surface in collisions between fast protons and silicon as a function of the angle of incidence and as a function of the layer depth where the ele…
The demand of nanocomposites for filler properties which is expected utilization. Natural minerals are keeping one of the prior positions in that significance. The thermal properties and strength of the requested properties expected to be improved for polymeric materials. Modification of that layered materials is stil…
BaTiO3 thin film was prepared by the self-assembled monolayers technique and liquid phase deposition. The effects of pH values and the deposition temperature on the formation of BaTiO3 film were studied. The results showed that the Si substrate was in the precursor solution with 0.025mol/L (AHFT/BN/BA=1:1:3) and pH= 1…
We report on the effect of PET substrate preheating on the characteristics of the flexible and transparent indium tin oxide (ITO) electrode grown by a specially designed roll-to-roll sputtering system for touch panel applications. It was found that electrical and optical properties of the roll-to-roll sputter grown IT…
Two PET scanner modules have been built in order to demonstrate the AX-PET concept in a phantom test. Each module comprises 6 layers of 8 LYSO crystals (3x3x100) mm3 orthogonally interleaved with layers of 26 wave length shifting strips (WLS) with dimensions (0.9x3x40) mm3. The spatial resolution is defined by the dim…
Soft magnetic composite films were prepared with butyl rubber as the base and Fe78Si9B13 amorphous powders for magnetic reinforcement, and its piezomagnetic effect was also tested. The results showed that the composite film had excellent piezomagnetic effect under low frequency; the impedance of composite films decrea…
The thermal fatigue behavior of alumina-magnesia based and alumina-chromia based purging plug materials are comparatively studied. By comparing thermal shock parameters, the changes of elastic modulus and hot modulus of rupture after thermal shock cycles, we come to a conclusion that microcracks emerge in the alumina-…
In this work, we have investigated the influence of the pulsed substrate bias voltage on the evolution of the surface morphology and sp3 hybridization degree of Ag containing diamond-like carbon (Ag-DLC) films deposited by using a mid-frequency dual-magnetron sputtering system. The unipole substrate bias voltage at 0…
Abstract The cover picture shows a Pd‐promoted homocoupling reaction of polyenylsilanes carried out in water containing nonionic amphiphiles. The reaction in the “green” aqueous environment affords extended conjugated polyenes with higher yields relative to those obtained when the same process is performed in organic…
Effect of NaAc on the anodic growth of TiO2 nanotube arrays is described. NaAc-added approach yields longer nanotubes relative to samples grown from NaAc-free electrolyte. And the growth rate of TiO2 nanotubes has pH independency in NaAc-added electrolytes. The key to achieve a high aspect ratio TiO2 nanotube arrays i…
We study the Photoluminescence (PL) and raman properties of porous silicon as function of etching time and current density. The result shows that PL spectra give a blueshift trend and increasing intensity when etching time and current density increase. Samples that strongly emit at visible range then were analyzed usi…
Based on an extensive comparison of test methods for abrasion resistance from home and abroad, a new technique for abrasion resistance at elevated temperature has been developed with some improvements. Two connected airtight chambers are designed to prevent compressed air from entering the sample chamber, so that heat…
The parameters, such as thermal expansion coefficient and Young's modulus, are considered as a function of temperature and incorporated into ANSYS code to calculate the stress field of UHTCs under high temperature condition in the present work. The stress fields of two kinds of heating cases are calculated and compare…
Abstract We introduce an effective local therapeutic strategy using a combined treatment with: a) increased and stable loading of doxorubicin (Dox) in liposomes using a complex of Dox and copper (II), b) suppression of tumor proliferation using rapamycin, c) insonation of the entire tumor to increase microvascular per…
The paper discusses modeling of carbon nanotubes as dipole antennas. The current distribution on a nanotube dipole has been analyzed using the method of moment approach. Thus a graph depicting the variation of current magnitude with respect to the length of the wire has been obtained and compared with that of a regula…
