The fracture mechanism of the thermal barrier coating of gas turbine blades is studied. The causes of the fracture of the ceramic layer are discussed and the possible ways to increase the fatigue life of the thermal barrier coating are considered.
We already know Temperature that was made from Self-heating phenomenon effects on memorys important functions (reading, writing, detection, etc...). Through simulations, we could identify that the temperature was changed by Insulator and Pillar size in MTJ. therefore we could found what insulator and size of pillar oc…
We investigate the IOFFvs. IONperformance of black phosphorus (BP) MOSFETs with thin HfO2gate dielectrics. IONand IOFFwere found to increase with increasing the BP thickness, with IOFFincreasing substantially at high drain-to-source voltage, VDS. Specifically, at VDS= -0.8 V, a body thicknessOFF<; 100 nA/μm. This work…
High-frequency induction plants are widely used to melt high-purity refractory metals and to conserve radioactive wastes in a glassy mass. The regimes of operation of such a plant are simulated, and the optimum conditions of stable energy transfer to a melting crucible are revealed.
While Boolean logic has been the backbone of information processing, there are computationally hard problems like optimization and classification wherein this conventional paradigm is less efficient. This motivates us to explore new pathways to their solution. In this invited talk, we describe an experimental testbed…
Carbon Nanotube (CNT) memory has a simple structure, low voltage, low current, and fast switching mechanism, and endurance up to 1012cycles has been demonstrated [1]. In order to optimize set and reset algorithms and understand the mechanisms of CNT reliability, this work studies the CNT after 107endurance cycles for…
En la actualidad, industrias como la aeroespacial y la aeronautica estan introduciendo materiales ceramicos en la produccion de elementos estructurales o sistemas de propulsion, impulsados por las excelentes propiedades de este tipo de materiales. En particular, materiales como el SiC y compuestos de C/C y SiC/C son u…

We investigated the ballistic transport characteristics of black phosphorus tunneling transistors using BP hetero-junction with thicker BP film at the source-channel interface. With the reduced tunneling barrier width on-current can be increased over 6 orders in 1L-2L-1L ZD BP heterogeneous TFETs compared with 1L BP h…
The ways to obtain high-quality licorice extract (LE) micro-particles have a large impact on their aqueous solubility and bioavailability. Researchers have addressed their preparation and property modification problems. A new issue arises when decision-makers want to determine automatically the best process parameters…
A series of chalcogenide glasses of various compositions, based on the TlI–Ag 2 S–As 2 S 3 system, were prepared. The conductivity parameters and diffusion coefficients of silver and thallium radiotracers in the glass samples were determined. Chemical sensors with membranes of four glass compositions were prepared, an…
The detonability of aqueous suspensions of solid explosives (pentaerythritol tetranitrate, cyclotrimethylenetrinitramine, cyclotetramethylenetetranitramine) was used as a basis for evaluating the explosion safety of these substances in production and transportation. The dependence of the critical detonation parameters…
After Fukusima 1 nuclear power plant accident in Japan, lots of measures have been taken to strengthen the safety of the nuclear power plant. One of them is stress test, which evaluates the maintainability of plant safety assuming the most severe condition that has no power supply and ultimate heat sink. This report d…
The docking system seal designed for astronauts activity is widely used in manned space systems such as habitable vehicles and Tiangong for mission to in-space mating and docking or deep space. The docking system seal adopts the seal-on-flange configuration, which is expected to has low leak rates to ensure the safety…
The synthesis of poly(3-hydroxybutyrate/3-hydroxyvalerate/3-hydroxyhexanoate) [P(3HB/3HV/3HHx)] and poly(3-hydroxybutyrate/3-hydroxyhexanoate/diethylene glycol) [P(3HB/3HHx/DEG)] by Cupriavidus eutrophus B10646 was studied. Cultivation conditions of Cupriavidus eutrophus B10646 enabled production of high biomass yield…
When asphalt pavement weeps, moisture collects in the sub-base layer and is pushed to the surface through a crack. Beads of water collect and spread on the surface, which is especially hazardous for racetracks. So when this phenomenon occurred at Watkins Glen International racetrack in New York, crews began the proces…

The study addresses synthesis and intracellular degradation of copolymers consisting of 3-hydroxybutyrate and diethylene glycol (P(3HB)/DEG) by Cupriavidus eutrophus -10646. DEG addition to the medium at concentrations of 10-30 g/L did not influence the yields of biomass and polymer. During intracellular degradation,…
Fibrous scaffolds from polymer solutions of poly-3-hydroxybutyrate, polylactide and polyglycolide, and copolymer of poly(lactide-glycolide) were obtained using electrostatic shaping with one or two feeding capillaries on one collecting manifold and their characteristics were studied.The spatial distribution of fibers…
Layout of the metal framework, which is widely placed in the power engineering, has effects on the electric field distribution. And moderate electromagnetic environment contributes to the health of staff in the high-voltage substation. Hence, in order to improve the exposure situation in the outdoor substation, the pr…
