The shock compression of a heterogeneous material is numerically simulated. The physical model used for the simulation is based on a layered model of a porous material and consists of a set of thin matrix plates with a known equation of state that are separated by filler layers also with a known equation of state. The…
In this study, we investigated the nucleation and growth of TE 3 SiC 2 by an interfacial reaction between a SiC substrate and a Ti/Al bilayered film at various temperatures. The specimens were prepared by depositing Ti/Al on a 4H-SiC substrate and subsequently annealing the substrate in a vacuum. The interfacial struc…
Controllable electrical breakdown of multiwall nanotubes (MWNTs) is studied utilizing the atomic force microscopy (AFM). Electrical breakdown has been known as the way to fundamentally understand the electrical properties of nanotubes and an approach to develop MWNT based transistors and sensors. Normally, electrical…
A high rate and efficient procedure for the synthesis of azo dyes has been developed. This concluded the sequential diazotization-diazo condensation of aromatic amines such as 4,4′-sulfonyldianiline with NaNO 2 , or trichlorotriazine with coupling agents under ultrasound irradiation at room temperature. This method ap…
The conversion luminescence of a phosphor from the ultraviolet region to the visible region can enhance the light harvesting in dye-sensitized solar cells (DSSCs), because many dyes can only absorb visible light. To explore the influence of phosphor additives on the conversion efficiency of DSSC, we introduce the nano…
This article focuses on the analysis of stresses within a thin-walled vessel. Focused on rotary symmetrical shell, boundary faults arising at the junction of the cylindrical part of the vessel and its bottom are monitored. The bottom of the vessel is designed in three variants and obtained values of stresses are compa…

For predicting the behavior of wood products with a final finish by applying polyurethane coatings (mainly solvent) under realistic conditions of use is extremely important to monitor all quality characteristics (physical, mechanical, chemical and performance) as well as fire-engineering based on selected characterist…
A capacitive Frisch-grid CdZnTe detector with different lengths of the Frisch rings has been fabricated, and the influence of infrared (IR) stimulation on the spectral performance of the detector has been investigated. IR stimulation at a wavelength (940 nm), close to the absorption edge of the CdZnTe, was found to im…
On page 5137, X. Zhan and co-workers report a novel nonplanar star-shaped perylene diimide electron acceptor with a triphenylamine core (S(TPA-PDI)). The S(TPA-PDI) exhibits weak molecular aggregation, strong absorption in the visible region, and appropriate energy levels matched with low-bandgap polymer donors. Solut…
Zinc oxide (ZnO) is a new material used in electronics applications such as spintronics, diluted magnetic semiconductor (DMS) and thin films. In this paper, the findings in fabrication and characterization of ZnO nanoparticles are reported. ZnO thin films were deposited onto glass substrates using a spin coating techn…
The wetting of Ag, Pt, Pd, Au, and Ir by Bi 2 O 3 -GeO 2 (SiO 2 , TiO 2 , B 2 O 3 , ZnO) melts has been studied as a function of the melt temperature and composition. It is shown that the melts most weakly interact with iridium.
Porphysome is the most stable and efficient delivery system of porphyrins, but the nanostructure converts the singlet oxygen generation mechanism to a thermal ablation mechanism. On page 1240, by incorporating targeting ligands (e.g. folate) into porphysome formulation, G. Zheng, J. Chen, and co-workers show that rece…
The influence of different fiber pulping on the resulting fibers properties are investigated, as well as the impact of saponification on the properties of pure CAB. Mechanical test of compounds with short fiber reinforcement and TPC-sheets manufactured with varying process parameters are carried out.
Available medical therapy is unable to completely prevent or revert the pathological cardiac remodeling secondary to ischemia or other injuries, which is responsible for the development of heart failure. Regenerative medicine through stem cells had an explosive development in the cardiovascular area during the past de…
O objetivo deste trabalho foi a purificação e organofilização em escala piloto de dois tipos de argila bentonita (cinza e verde) com tensoativo não iônico e a aplicação destas argilas em nanocompósitos com matriz de Polipropileno (PP). As argilas foram purificadas e em seguida organicamente modificadas com tensoativo…
A drop tube‐impulse atomization technique was used to produce D2 tool steel powders. Shadowgraph (Sizing Master Shadow from LaVision GmbH in Göttingen, Germany) was utilized to measure in‐situ velocity and droplet size. Simultaneously, the DPV‐2000 (Tecnar Automation Ltée, St. Hubert Quebec, Canada) was used to measur…
Proton exchange membrane fuel cells (PEMFCs) are very promising for power stationary applications. One of the key components of fuel cells is the flow field plate through which hydrogen fuel will reach the anode and oxygen reach the cathode. Another function of the flow field plate is the electron collection. Traditio…
Adv. Mater. 2013, 25, 3234–3237 The caption of Figure 4 in article adma.201300776 is hereby corrected to: Emission spectra at 30 °C (a) for a CLC shell of DBR mode (R = 107 μm, a = 72 μm) and (b) for a CLC shell of DFB mode (R = 107 μm, a = 92 μm) by pulsed pumping laser light of wavelengths of 450 nm and 510 nm, resp…
Nonvolatile memories have emerged in recent years and have become a leading candidate towards replacing dynamic and static random-access memory devices. In this article, the performance of physical TiO2and TaO2nonvolatile memristive devices were compared in terms of switching speed, retention and endurance. TaO2memris…
