Today the domains of life-respecting, degradable therapeutic materials and devices are among the most attractive areas in polymer science. Increasing attention is being paid to polymeric compounds that can be bioresorbable, i.e., degradable and ideally excreted or bio-assimilated - suitable to treat human diseases or…
Small- and wide-angle X-ray scattering in solution reveals that chlorophyll (Chl) trefoils self-assemble in the presence of 1,4-diazabicyclo[2.2.2]octane (DABCO) to yield supramolecular cyclic trimers. Two Chls of each trefoil coordinate to DABCO to form the vertices of the hexagonal structure, while the remaining Chl…
Magnetic and structural properties in multifunctional FSMA (Ferromagnetic Shape Memory Alloys) belonging to Heusler family are frequently related to the occurrence of structural modulation in martensitic phases. The highest MFIS (Magnetic Field Induced Strain) effect has been observed in Ni-Mn-Ga alloys showing marten…
A model is discussed for magnetoelectric (ME) coupling in a nanobilayer of ferromagnetic and piezoelectric phases on a substrate. The theory is applied to a specific case, nickel ferrite and lead zirconate titanate bilayer on strontium titanate substrate. Both low-frequency coupling and ME interactions at frequencies…
Abstract The preparation and characterization of intercalated kaolinite is important for industries such as those using nanocomposites, but the number of compounds that can be intercalated into these clay minerals is rather limited. The purpose of this study was to expand the range of possible intercalants by developi…
Abstract: The latest development of protein engineering allows the production of proteins having desired properties and large potential markets, but the clinical advances of therapeutical proteins are still limited by their fragility. Nanotechnology could provide optimal vectors able to protect from degradation therap…
Ba ( Ti 1-x Zr x ) O 3 ; BTZ (x = 0.20 and 0.25) ceramics are attractive candidates for dynamic random access memories, tunable microwave devices and capacitors. In this study, the preparation of BTZ powders and ceramics fabricated by the combustion method were studied in detail. The calcination and sintering conditio…
The total and hole (p-type) conductivities are measured in the BaZr1 − x Y x O3 − α system (x = 0.02−0.20) in the temperature range of 600–900°C as a function of air humidity (pH2O = 0.04−3.17 kPa). The model of defect formation in BaZr1 − x Y x O3 − α oxides in the presence of water vapor is discussed and the literat…
The Shark Skin Effect (A Lang) Lotus Effect: Superhydrophobicity and Self-Cleaning (M Nosonovsky & E Bormashenko) The Moth-Eye Effect - From Fundamentals to Commercial Exploitation (A Gombert & B Blasi) The Gecko Effect: Design Principles of the Gekkotan Adhesive System Across Scales of Organization (A Russel & M John…
In this paper we show how numerical and analytical modeling of graphene-based devices is used to consider possible approaches to engineer a gap in graphene and to evaluate the perspectives of different technological options towards graphene nanoelectronics.
Abstract A procedure to prepare macroporous silica gels from an acid-catalyzed tetraethoxysilane (TEOS)–water binary system was developed, and the macroscopic morphology formation was examined at a range of conditions under controlled reaction temperature. This procedure involves two-step mixing of TEOS and water cont…
This contribution summarizes the work that has been performed to establish the industrial production of tungsten coatings on carbon fibre composite (CFC) for application within the ITER-like Wall Project at JET. This comprises the investigation of vacuum plasma-sprayed coatings, physical vapour deposited tungsten/rhen…
The mutual solubilities and related liquid-liquid equilibria of 19 binary systems of C2 to C4 esters with water are exhaustively and critically reviewed. Reports of experimental determination of solubility that appeared in the primary literature prior to the end of 2007 are compiled. For ten systems, sufficient data a…
It has long been suspected that physical chain entanglements in the amorphous phase affect the strain hardening behavior of polyethylene. The precise number of chain entanglements in solid polyethylene cannot be measured using any current techniques. Since entanglements in the melt state are known to be preserved in t…
The ITER-like wall project in JET aims at an optimal use of the unique features of JET, such as beryllium and tritium compatibility, to explore operation within the limits of the ITER wall materials. A full replacement of the presently carbon-based first wall will result in the surfaces facing the plasma being mainly…
Problem statement: The effects of gamma irradiation on optical properties of cresol-red dyed Poly Vinyl Alcohol (PVA) blended with Trichloroacetic Acid (TCA) for possible use in dosimetry and measurement of radiation dose in gamma rays have been studied using both Raman spectroscopy and UV-Visible spectrophotometer me…
In this paper, we address the differences between Finnis–Sinclair potentials and bond-order potentials (BOPs) when studying 1/2⟨111⟩ screw dislocations in bcc transition metals, specifically Mo and W. These two types of potentials differ in that the former is central-force, whereas the latter include angular bonding.…
We present a computational approach based on the Volume-of-Fluid (VOF) method for simulating the influence of a soluble surfactant on the behavior of two-phase systems with deformable interface. Our approach is applicable to diffusion controlled processes, where the relation between the area-specific excess surfactant…
Abstract Modified acrylonitrile‐styrene‐acrylate (MASA) were prepared by grafting with maleic anhydride and optimization was carried out. The compatibilizer with four parts of ASA‐ g ‐MA in 10 parts of acrylonitrile‐styrene‐acrylate (ASA) was found effective in improving the interface. On that basis, the different com…
Abstract In X-ray diffraction (XRD) analysis, preparation of oriented clay specimens enhances their 00 l reflections by arranging basal surfaces parallel to the specimen surface. In one-dimensional modeling of XRD intensities, degree of preferred orientation is one of the variable parameters and a user may choose diff…
