We fabricated a carbon nanotube (CNT) via interconnect and evaluated its robustness over a high-density current. CNTs were synthesized at temperatures as low as 365 °C, which is probably the lowest for this application, without degrading the ultra low-k interlayer dielectrics (k = 2.6). We measured the electrical prop…
Detecting insulation flaws in HVDC apparatus, where partial discharge (PD) may occur can help preventing failures, even if the degradation rate under PD is much slower than in AC conditions. In order to improve reliability of HVDC systems and, in particular of HVDC transmission lines, it would be important to distingu…
Abstract The effect of a Mg- and Al-containing layered double hydroxide (LDH), used as an additive or as a matrix, on the dissolution and solubility of two non-steroidal anti-inflammatory drugs (NSAIDs), namely, mefenamic and meclofenamic acids, is reported. The use of MgAl-LDH enhances the solubility of mefenamic aci…
Investigations dealing with the treatment of aqueous systems by physical methods show that ultrasound is an effective reagentless and highly ecological method of water purification of organic pollutants and microorganisms. Its use is particularly effective in combined methods of treatment: ultrasound + ultraviolet irr…
Density functional theory calculations were performed to obtain an atomistic understanding of facet formation on Ir(210). We determined geometries and energetics of clean and oxygen-covered surfaces of planar Ir(210) as well as Ir(311) and two types of Ir(110) surfaces, which are involved in faceting by forming three-…
Graphene, a recently discovered form of carbon, revealed many unique properties, including extremely high electron mobility of ~15000 cm2/Vs at room temperature (RT). We have experimentally studied the thermal conductivity of graphene suspended over a trench in silicon (Si) wafer. It was found for a given set of sampl…
We develop a theoretical and computational model to investigate the ballistic response of a hybrid twolayered flexible armor system.In particular, we study the effects of stacking order of the two fibrous layers, which have distinctly different mechanical properties, on the V 50 limit velocity.A system consisting of K…
Abstract: Boron carbonitride (BCN) thin films with a thickness of ~4 µm were synthesized on Si (100) substrate by radiofrequency and microwave plasma enhanced chemical vapor deposition using trimethylamine borane [(CH3)3N.BH3)] as a molecular precursor. The microstructures of the films were evaluated using field emiss…
In this paper, a series of organic-inorganic hybrid materials consisting of epoxy resin frameworks and dispersed nanoparticles of amino-modified silica (AMS) were successfully prepared. First of all, the AMS nanoparticles were synthesized by carrying out the conventional acid-catalyzed sol-gel reactions of tetraethyl…
With an increasing ageing population, the incidence of pressure sores and incontinence is becoming an increasing burden on the health sector and requires new forms of intervention. Three dimensional knitted spacer fabrics can afford a range of properties making them ideal for use against the skin in a variety of medic…
At room temperature, the effect of KrF pulsed excimer laser irradiation on the structural, photoluminescence, and electrical properties and on the surface morphology of ZnO thin films under different laser energy densities was investigated. Compared to the as grown sample, at an irradiation energy density of about 450…
A diamide molecule bearing a biotin terminus was bonded via an amide linkage to the surface of an aminated single-walled carbon nanotube and examined by a high-resolution transmission electron microscope. The still and movie images allowed us to study not only the conformation of the molecule but also its time evoluti…
In this study, we analyze the effect of surface anisotropy on the magnetic properties of magnetite Fe3O4 nanoparticles on the basis of a core-shell model. Magnetization, magnetic susceptibility, and specific heat are computed over a wide range of temperatures. In our model, we stress on magnetite nanoparticles of 5nm…
Abstract Epiphytic algae occurring on submerged macrophytes were investigated as part of a study on the ecological status of a shallow macrophyte-dominated lake, Lake Skomielno, which has been used for recreation and fishery. Relatively high variability in biomass (DM) and chlorophyll a contents in epiphyton on partic…
Functional fibrous materials are a new family of fibre materials whose physical and chemical properties are sensitive to the change in the environment such as temperature, pressure, electric field, magnetic field, optical wavelength, adsorbed gas molecules and the pH value. This paper introduces a new approach to tran…

A tube-in-square-pipe microfluidic glass cell has been developed for studying the aggregation and fiber formation from regenerated silk solution by in-situ small-angle X-ray scattering using synchrotron radiation. Acidification-induced aggregation has been observed close to the mixing point of the fibroin and buffer s…
The microstructure of a duplex stainless steel slab 1.4362 produced by continuous casting has been investigated by optical microscopy, scanning electron microscopy, EBSD and EDS. The slab showed different macrostructures through the thickness. The macrostructure can be divided into 3 types: fine equiaxed, columnar and…
Electric discharge between the tip of an icicle and a plane electrode has been studied because of its relevance to the flashover of high voltage ice-covered insulators. A photomultiplier was used to scan the high voltage rod simultaneously with current measurement technique. The basic properties of streamers, namely t…
Environmental stress cracking resistance (ESCR) is an important indicator of performance for high density polyethylene (HDPE) in structural and polymer pipe applications. The commonly used test for determining ESCR of HDPE can be time consuming and rather imprecise. A tensile strain hardening test was recently propose…
