Electron transmission through insulating Al 2 O 3 nanocapillaries of different diameters (40 and 270 nm) and 15 μm length has been investigated for low-energy electrons (2–120 eV). The total intensity of transmitted current weakly depends on the incident electron energy and tilt angle defined with respect to the capil…
Abstract The electrical and thermal conductivity of nanocarbon filled polymers were studied by adding nanocarbon fillers (thermoexfoliated graphite (TEG) and dispersed TEG (nanoTEG)) to epoxy resin (ED) or polyethylene oxide (PEO). The content of filler in composite materials (CM) was (0.5–10) wt%. The temperature ran…
Direct and reverse martensitic transformations have been studied in Mn50Ni40In10 ribbons by means of magnetization and electrical resistivity measurements. The alloy is L21-type single-phase austenite, which transforms into a 14M monoclinic martensite. The martensitic transformation is accompanied by a large change in…
Abstract An environmentally friendly and economically efficient method has been developed to synthesize monodisperse CeO 2 ‐ZrO 2 solid solution nanocrystals. In this process, the formation of oleate‐stabilized Ce 0.5 Zr 0.5 O 2 nanocrystals was designed to proceed through hydrolytic sol–gel condensation of metal–olea…
Extensive testing has been performed at the Lawrence Livermore National Laboratory (LLNL, Livermore, California) to determine the corrosion characteristics of nickel-based alloys such as Alloy 22 (UNS N06022) and three titanium alloys. The studies focused on three major areas: immersion tests at the long-term corrosio…
The phase-change memory (PCM) technology represents one of the most attractive concepts for next generation data storage. PCM behavior is mainly limited by the structural relaxation (SR) and by the crystallization of an amorphous chalcogenide material: the ternary alloy Ge2Sb2Te5. SR is a local structural-rearrangemen…
Water-stable aggregates isolated from three subtropical and one tropical soil (Western Georgia and China) were studied for their organic carbon, cation exchange capacity (CEC), specific surface area, magnetic susceptibility, and total chemical elements. The soils were also studied for their particle-size distribution,…
Abstract Viscoelastic ature is one of the key features of polymeric composites. A series of cyanate ester (CE)‐based composites with different aluminum nitride (AlN) contents for high performance electronic packaging, coded as AlN/CE, were developed; the viscoelastic nature of AlN/CE composites was intensively investi…
Electromigration results are described for a dual damascene structure with copper metallization and a low-k dielectric material. The failure times follow a bimodal lognormal behavior with early and late failures. Moreover, there is evidence of a threshold failure time such that each failure mode is represented by a 3-…
The EMF method with a solid Ag 4 RbI 5 superionic conductor was used to study the Ag-As-Se and Ag-S-I systems in the composition ranges of Ag 2 Se-As 2 Se 3 -Se and Ag 2 S-AgI-S, accordingly. Their solid-phase equilibrium diagrams are constructed or specified. The existence of ternary AgAs 3 Se 5 , AgAsSe 2 , Ag 3 AsS…
Abstract Nineteen activated carbons, including sixteen tailor-made and three commercially available ones, were employed to investigate their role in the one-pot synthesis of 2-arylbenzazoles starting from 2-aminophenol, 1,2-diaminobenzene, or 2-aminobenzenethiol, and aldehyde via oxidative cyclization of intermediate…
The temperature dependences of the specific magnetization σ and the electrical resistivity ρ of Me x Mn1 − x S single crystals (Me= Co, Gd; x= 0.05) have been studied in the temperature range 80 K < T < 1000 K. The samples under study have revealed the presence of a spontaneous magnetic moment below the Néel temperatu…
We report the synthesis and characterization of a new electron-doped La-oxypnictide superconductor by partial substitution of lanthanum by thorium. The superconducting transition temperature at about 30.3 K was observed in La(0.8)Th(0.2)FeAsO, which is the highest in La-based oxypnictide superconductors synthesized at…
Microcellular foamed plastics have significantly contributed to the plastics industry by achieving product's weight reduction and material cost savings. Limitations in petroleum resource reserves have propelled recent active research into the area of the foaming process. In particular, the extremely small cell size at…
Panichiite, ammonium hexachlorostannate(IV), (NH 4 ) 2 SnCl 6 , is a new mineral species found in a medium-temperature intracrater fumarole (~250°C) at La Fossa crater, Vulcano Island, Aeolian Islands, Sicily, Italy. The mineral occurs as aggregates of minute colorless octahedra up to 0.2 mm in diameter on fragments o…
Abstract We propose a new mechanism of recrystallization of cold-deformed metals. During the cold deformation, some of the high-angle grain boundaries are moved by the applied stresses, producing low-curvature bulges and leaving almost defect-free regions behind. The driving force for this motion is very high and can…
Abstract This paper describes a novel process that is stretching‐controlled thermal micromolding, to fabricate bionic superhydrophobic polyethylene films. Low‐density polyethylene was thermally pressed in a vacuum oven onto PDMS stamps replicated from lotus leaves. After being cooled and peeled off from the stamps, th…
Abstract We introduce a new material point homogenization scheme – the ‘Relaxed Grain Cluster’ (RGC) – based on a cluster of grains and formulated in the framework of finite deformations. Two variants of this scheme, which allow for different degrees of relaxation, are compared to two variants derived from the infinit…
In recent years, a wide range of different methods to implant nanosized patterns on surfaces have been developed. Spin coating immiscible binary polymer blends is a straightforward method to prepare micro- and nanostructures on thin films. This study utilizes binary blends to effortlessly prepare stable, surface-funct…
Magnesium oxide (MgO) has been investigated as a possible candidate for gamma (γ) dosimetry. One thermoluminescence (TL) peak was observed in the red emission band around 372 °C in the pristine sample. The glow curves indicate that the main TL peaks appear at nearly the same temperatures after γ and ultraviolet irradi…
