Low resistivity Cu wires were developed by the combination of lessening impurities through additive-free plating and high heating rate annealing. Resistivities of Cu wires made with the new method were about 30% lower than those made by conventional plating with additives and annealing at the same temperature in H2. L…
The radiation properties of an axially slotted elliptic antenna coated with magnetic metamaterials are investigated. The fields inside and outside the dielectric coating are expressed in terms of the Mathieu functions. The boundary conditions at various surfaces are enforced using the orthogonality property of angular…
Enthalpies of dissolution of tetrapyridylporphyrin (TPyP) derivatives, in which the pyridine nitrogen is located in para-, metaor ortho-positions and is modified by nonpolar (-CH3,-C2H5,-C3H7), polar (-CH2COOH, -CH2CH2COOH) and low-polar (-CH2COOC2H5) groups, are determined in water by calorimetric method for the firs…
INTRODUCTION: Patients with implanted bioprostheses are at risk of structural dysfunction which results from the limited durability of biological valves. The aim of this study was to analyse the mechanism of bioprosthesis degeneration and to evaluate the usability of transthoracic and transoesophageal echocardiography…
We have developed a silane-free atmospheric-pressure plasma Si deposition process and investigated the properties of the deposited films by fabricating strain gauge type pressure sensors for the first time. The Si deposition process, which is known as plasma-enhanced chemical transport, utilizes the temperature differ…
In this work, the syntheses and characterization of oxygen deficient perovskite cobalt oxides prepared under ambient pressure conditions with different “x” in the Co(Sr1-xYx)O3–δ; 0.05 ≤ x ≤ 0.4 series are reported. The system studied in the present investigation undergoes structural phase transition at room temperatu…
In this letter, a compact planer dual-band bandpass fllter (BPF) using novel split-ring resonators (SRRs) is proposed. Compared with conventional SRRs, the stepped impedance split ring resonator (SIR-SRR) has better performance on miniaturization. To verify good characteristics of the novel structure, a new resonator-…
The main objective of this paper was to develop a more advanced finishing treatment for the stitch shape regularity and dimensional properties of knitted fabrics. In our previous work, we presented a novel definition of knitted fabric regularity. In the present study we utilised our per vious approach based on Radon t…
Experimentally observed trends in energy barriers at interfaces of different semiconductors (Si, Ge, GaAs, InP) with wide-gap oxide insulators are overviewed, revealing general features over a wide spectrum of studied materials. In particular, we found that the energy position of the O2p-derived oxide valence band rem…
The sheet hydroforming with punch (SHF‐P) process offers great potential for low and medium volume production, especially for forming: (1) lightweight sheet materials such as aluminum (Al) and magnesium (Mg) alloys and (2) thin gage high strength steels (HSS). Mg and Al alloys are being increasingly considered for aut…
Cyclic radical anneal was interposed in atomic layer deposition (ALD) of gate dielectrics on Si. A significant improvement on the thermal stability of the gate dielectrics against postdeposition anneal (PDA) can be achieved from the incorporation of this special anneal technique into the ALD process. A low equivalent…
Software-information system Protein Structure Discovery was developed. The system can be used for the wide range of tasks in the field of computer proteomics including prediction of function, structure and immunological properties of proteins. A specially created section of the system allows evaluating the quantitativ…
The use of stainless steels as concrete reinforcement is becoming increasingly popular in coastal and marine constructions in order to prevent corrosion induced by chloride ions penetrating into the concrete. In these highly aggressive situations, the lean duplex stainless steels have been extensively employed due to…
Concrete deterioration results in different damage extents, from cracking to concrete spalling, from losses of reinforcement cross-sections to bond losses. A relevant prediction of this performance is the basis for a successful management of the concrete structures. Conversely, the large amount of uncertainties relate…
The interest in developing multifunctional materials has greatly increased in the last decade. Power storage composites are just one class of multifunctional materials that has the potential to lead to significant size and weight reduction. Many electronic devices (i.e. laptops, cellphones, iPods, etc.) and mechanical…
The aim of the present paper was to obtain new solid forms of Norfloxacin. For this purpose Norfloxacin was recrystallized from: acetic acid and its mixtures with several organic solvents. By recrystallization of Norfloxacin from acetic acid and from its mixture with several organic solvents a new solvate was found. T…
Cryosectioned granules were observed in microstructure, Extracellur Polymeric Substances (EPS) and metal distribution. Aerobic granules composed of pores and channels that were not plugged by EPS, with rather open structure. Microorganisms proliferated mainly on the surface of granule and on the wall of channels, carb…
SYNTHESIS AND CHARACTERIZATION OF SUPERABSORBENT POLYMER COMPOSITES BASED ON ACRYLIC ACID, ACRYLAMIDE AND BENTONITE . Superabsorbent polymer (SAP) is a hydrogel material which is capable of absorbing and or storing liquid up to a hundred times of its dry weight. SAP was synthesized from monomers of acrylic acid and ac…
With the capability to change between reflective and transparent states, electrochromic switchable mirrors are expected to have numerous applications in optical devices, electronics devices and new energy-saving windows. If conventional windows can be adapted to incorporate switchable mirror technology, the solar radi…
The role of fluorine and phosphonate groups on protein structure and biocompatibility has been probed by protein encapsulation in tetramethoxysilane (TMOS)-based sol-gel glass and assessed by circular dichroism spectroscopy (CD). Apomyoglobin (apoMb) is known as a model protein for the study of protein folding. Thus,…
