This paper presents a characterization of a crosslinked EVA residue (EVA-c) from expanded sheets used in the shoe industry and post-consumer urban-waste polyethylenes regarding their molecular (FTIR), mechanical (tensile and impact tests), morphological (SEM), thermal (DSC, TGA) and dynamic-mechanical (DMTA) propertie…
We report the basic characteristics of super resolution near-field structure (Super-RENS) media at a blue laser optical system (laser wavelength 405 nm, numerical aperture 0.85). Using a novel write once read many (WORM) structure for a blue laser system, we obtained a carrier-to-noise ratio (CNR) above 33 dB from the…
In this work Carbon nanotubes have been synthesized by arc discharge in open air. A TIG welding ac/dc inverter was used as the power source for arc discharge. During each run of the arc discharge based synthesis, the anode was a low purity (approximately 85% C by weight) graphite rod. The effect of varying the atmosph…
Abstract We propose and demonstrate a nano‐structured alignment layer which is capable of producing pretilt angles of any value from 0° to 90°. This alignment layer is robust, stable, reliable and highly manufacturable. We utilized these alignment layers to obtain ∼45° pretilt angles to make a pi‐cell which is in the…
Porous GaAs (100) and (111) substrates with nanostructured (∼10 nm) surface profiles are obtained in which pores branching in the 〈111〉 direction form a dense network with a volume density of ∼60% under the surface at a depth of ∼(50–100) nm. The surface of the substrates and the structure of GaSb layers grown on thes…
The thermal transformation of spin-cast thin films to produce nanoporous low-k dielectric layers has been investigated using polymethysilsesquioxane (PMSSQ) for the low-k matrix and polymethylmethacrylate-co-dimethylaminoethylacrylate (PMMA-co-DMAEMA) as the porogen which is volatilized to leave nanopores in the matri…
The paper describes the vector magnetic characteristic analytical method using the vector magnetic hysteretic engineering model. By this method, various kinds of vector magnetic properties, for example vector hysteretic loop, coercive force, magnetic power loss, vector behavior of magnetic flux density B, and magnetic…
Surface relief grating formation was investigated for a series of azobenzene containing polymers with varying molecular weight. The polymers were obtained by a combination of an atom transfer radical polymerization of trimethylsilylethyl methacrylate and subsequent polymeranalogous introduction of the azobenzene chrom…
BaTi 0.975 Zr 0.025 O 3 thick-film microactuators were fabricated by combining screen printing and silicon micromachining. The electric properties of BaTi 0.975 Zr 0.025 O 3 thick films with a small area on a Pt bottom electrode using silicon substrates prepared by screen printing were investigated. The thick films we…
The thermal decomposition and foaming behaviors of blowing agent AC (azodicarbamide) and exo-endothermic blowing agent DDL-105 were investigated systematically. The gas and enthalpy release both showed that DDL-105 exhibited a milder decomposition. The blowing ratio and cell structure were influenced by the decomposit…

The optical properties and potential applications of four kinds of fulgide and fulgimide were studied. A parallel optical storage apparatus was set up, which could reach the area density of 4.8 × 107 bits/cm2 on the fulgide/PMMA film. Fourier transform orthogonal circular polarization holographic data storage was perf…
This work focuses on an experimental investigation of the thermodynamic properties of natural organic matter (NOM), and whether fractions of NOM possess the same thermodynamic characteristics as the whole NOM from which they are derived. Advanced thermal characterization techniques were employed to quantify thermal ex…
Statically determinate structures with truss elements have simple mechanisms, light weight, and high rigidity. Based on the flexural truss structure, a high authority actuator comprising a triangular truss core, a facesheet, and actuation elements is proposed. It is clamped at one end and free at the other. The actuat…
Methionine-42, distal to the active site of Escherichia coli dihydrofolate reductase, was substituted by site-directed mutagenesis with 14 amino acids (Ala, Cys, Glu, Gln, Gly, His, Ile, Leu, Pro, Ser, Thr, Trp, Tyr, and Val) to elucidate its role in the stability and function of this enzyme. Far-ultraviolet circular…
Die planktische Diatomee des Süßwassers Cyclotella comensis wird schalenmorphologisch beschrieben. Dabei wird historisches Material von 1890 und rezentes Material von 2001 aus dem locus typicus Comer See, Norditalien, rezentes Material aus dem Großen Boberowsee, Norddeutschland und Material aus Klonkulturen mit Urspru…
Magnetic measurements on Ni _{2-x} Cu _{x} MnGa with 0 ≦ x≦ 0.8 are made in the temperature range between 4.2 K and 440 K. A phase diagram of Ni _{2-x} Cu _{x} MnGa is determined from the results of the temperature dependence of the initial permeability. The Curie temperature T_{C} increases with the Cu…
It has long been known that transitional metal ions and acids in iron gall inks induce degradation of paper support, thus endangering numerous historical materials. Stabilization treatment should therefore consist of deacidification and addition of antioxidants that could be used for stabilization of all historical ma…
In theory, both polarity and steric hindrance are basic factors which affect molecular interactions. To investigate the optical properties and steric structures of chiral compounds having different chiral moieties which affect the wavelength of light reflection in liquid crystal (LC) cells, a series of novel chiral co…
This paper compares smectic phases formed from LC‐homo‐ and LC‐co‐polysiloxanes. In the homopolysiloxane, each repeating unit of the polymer chain is substituted with a mesogen, whereas in the copolysiloxanes mesogenic repeating units are separated by dimethylsiloxane units. Despite a rather similiar phase sequence of…
