We used the scanning electron microscopy and the electron backscattered diffraction to investigate a deformation relief and a crystallographic disorientation of a nickel [001] single crystal with {100} faces with a lateral incision. We identified that the lateral incision can change the shear domains distribution patt…
In this study, we focus on the sidewall of a single-walled carbon nanotube (SWNT) as a unique platform to probe ‘the smallest molecular assembly’ (dimers), which can be fully characterized microscopically, spectroscopically, and theoretically [1]. Theoretical calculations predicted that reactions of SWNT with aryl rad…
The development of polymer electrolytes has drawn the attention of many researchers in the last three decades as they find applications not only in lithium batteries but also, in other electrochemical devices such as super capacitors and electrochromic devices, etc. These polymer electrolytes have several advantages o…
Since natural nucleobases are not emissive, emissive nucleoside analogues have been widely used to monitor fundamental biochemical transformations directly. Nowadays, useful libraries of synthetic emissive nucleoside analogues have been constructed and researchers have a wide variety of choices. A typical approach to…

In modern metallization systems mechanical stress due to CTE mismatch is one of the reliability problems. With the help of finite element simulations the thermal-electrical-mechanical behavior can be calculated. The use of a reference temperature for the stress free state in the simulations is insufficient to determin…
Nowadays, lithium-ion batteries (LIBs) are widely used to power portable devices, microelectronics, vehicles, etc. With many advantages such as high surface area and improved charge transport, self-supported 3-D nanostructured metal oxides are promising electrode materials for LIBs and their impact is particularly sig…
Comparing with conventional solid oxide fuel cells (SOFCs) that typically operate at ~750 oC and above, intermediate temperature SOFCs (IT-SOFCs) that operate at temperature of ~400-700 oC offer advantages such as the possibility for the use of lower cost sealing and interconnect materials and the potential for improv…
The elastic and magnetic characteristics of single-crystal Nd0.9Dy0.1Fe3(BO3)4 are studied at low temperatures in zero magnetic field and in external fields H||C3. The temperature dependences of the acoustic mode velocities and the magnetic susceptibility manifest a transition of the magnetic subsystem into a magnetic…
Echogenic liposomes loaded with recombinant tissue-type plasminogen activator, rt-PA (tELIP), are under development for treatment of thrombo-occlusive disease. However, tELIP filled with air nucleate low stable cavitation activity when exposed to 120-kHz ultrasound, which limits the thrombolytic efficacy. We hypothesi…
The paper presents the effect of abrasive wear of the pipeline section occurred due to mechanical impurities in the transported gas flow. The approaches to the detection of the maximum specific wear of the pipeline wall and the geometry of abrasion are the main problems of computer simulation described in this paper.
Effect of temperature, roughness and washer shape on 254 SMO alloy was applied to study the susceptibility of alloy's crevice corrosion. XPS measurements have been carried out to detect and define the products which formed on the surface of 254 SMO in 22% NaCl at 30oC at applied potential 600 mVSCE. The formation of F…
Bubbles are well known for being strong nonlinear scatterers in acoustics. This feature is actually used in medical ultrasound, and nonlinear phenomena, such as phase conjugation [1] or second-harmonic generation [2], had been reported in bubbly liquids. We carried out experiments and calculations on a particularly si…
The use of diesel engines is becoming more widespread because their fuel economy is superior to and their emission levels of carbon monoxide and carbon dioxide are considerably lower than those of gasoline engines. However, the high-temperature combustion in diesel engines generates significant amounts of nitrogen oxi…
While performance of a lithium ion battery is primarily determined by the materials used within, the cell design variables also play a significant role. Parameters such as electrode thickness and porosity can influence overall cell energy density, power/rate performance, and lifetime. Ideally, a cell design needs to i…
Recently, endohedral species containing uranium ions have been detected by MALDI mass spectrometry. In this communication, we will describe the electronic and structural features for some new uranium endohedral fullerenes. In particular, we will discuss the potential different oxidation states of the uranium ions when…
The faster kinetics of nanostructured charge-storage materials are often accompanied by accelerated degradation and failure, compromising the potential advantages of nanostructure and nanoporosity. Understanding and controlling the exact mechanisms of this degradation is a complex materials characterization challenge.…
In this study, the polyamidoamine (PAMAM) dendrimer-encapsulated metal nanoparticles-modified electrodes were prepared in a two-step electrochemical approach. First, dendrimer molecules were grafted onto carbon surfaces by electrochemical oxidation of the terminal amine groups of PAMAM dendrimer in aqueous solution[1]…
In this paper, some of the failures and fractures caused by stress waves and shock waves resulting from impact and hypervelocity impact phenomena are presented and discussed. Furthermore, different designed and tested systems to protect the persons and the structural engineering members are also given and discussed. F…
A series of anthracene-based organic dyes were prepared via cost-effective synthetic procedures for dye-sensitized cell application. UV-visible and fluorescent spectra, electrochemical properties as well as photovoltaic performance of the dyes were studied. Under one sun (100 mW/cm2), the AN-3 small cell (area = 0.16…
