Nanowires and statistics: A statistical process for reading ultradense arrays of nanostructured materials is presented (see image). The experimental realization is achieved through selective nanowire growth using porous alumina templates. The statistical patterning approach is found to provide rigorous selection rules…
According to well known physical definition, electromagnetic waves are oscillating electric and magnetic fields traveling together through space. In the electromagnetic radiation spectrum, shown in figure 1, microwaves (300 MHz – 300 GHz) lie between radio wave (RF) and infrared (IR) frequencies, with relatively large…

Abstract Montmorillonite‐filled nanocomposites were prepared by the thermal copolymerization of tung oil (TUNG), styrene (ST), and divinylbenzene (DVB). These nanocomposites were characterized by X‐ray diffraction (XRD), transmission electron microscopy (TEM), dynamic mechanical analysis (DMA), and their mechanical pr…
The dynamic response characteristics of a liquid crystal (LC) device are dependent upon its viscosity coefficients. Local shear viscosity coefficients, or Miesowicz viscosity coefficients, ηi, are of particular importance for backflow effects and their optimisation allows for faster LC device response times. With such…
Various nanoparticles play a prominent role in modern biosciences and medicine. Especially fluorescent cellular biomarkers are a prospective material for diagnostics and therapy. Nevertheless, most of the available biomarkers have some drawbacks due to either physical and optical or cytotoxic properties. Here we inves…
The sn-2 acyl hydrolysis of phospholipids catalyzed by phospholipase A(2) (PLA(2)) was investigated at the density functional B3LYP level. The PLA(2) active site is represented by quantum-chemical models that are based on available X-ray crystal structures. The two still controversial catalytic triad and calcium-coord…
Spherical colloids with asymmetric surface properties, e.g., 'Janus' particles with two unique faces, are an emerging class of materials that can provide mechanisms for controlling colloidal particle dynamics. Several reports in the literature detail the fabrication of Janus particles as well as their behavior under t…
Quantum dot (QD) luminescent solar concentrator (LSC) uses a sheet of highly transparent materials doped with luminescent QDs materials. Sunlight is absorbed by these quantum dots and emitted through down conversion process. The emitted light is trapped in the sheet and travels to the edges where it can be collected b…
Investigations are performed to explore the surface morphological and crystallographic changes induced by the irradiation of laser-produced copper ions on 4N pure polished silver samples under vacuum (∼10−3 torr). The morphology was changed a great deal, with prominence in sputtering, hill and crater formation. Variat…
The formation process of a hemicyanine-terminated alkanethiolate self-assembled monolayer (SAM) on gold nanospheres immobilized on a glass substrate was studied by absorption spectroscopy, optical second harmonic generation, and Monte Carlo simulation. It was found that hemicyanine thiolate SAMs mainly form in the upp…
Flat textiles play an important role in clothing and as component of composites. Besides of that, it would be difficult to imagine the processes of filtration without the flat textiles. They can be divided into three main groups: woven fabrics, knitted fabrics and non-woven textiles if their design is disregarded. The…
We model how phytoplankton-produced exopolymeric substances (EPS) may change pycnocline thickness δz through control by Richardson number Ri. Shear stress τFORCED is imposed across the pycnocline, giving a shear rate δu/δz, where δu is cross-pycnocline velocity difference, modulated by viscosity η. In natural waters,…
Irradiation of ZnO single crystals by thermal neutrons with a dose up to 7×1017 cm−2 and subsequent annealing at 400 °C for 1 h leads to a significant increase in majority carrier mobility and concentration in this material, with the corresponding decrease of its sheet resistance. Additionally, cathodoluminescence spe…
Abstract ABS/layered silicate nanocomposites were synthesized through an emulsion polymerization with different sizes of silicates. The particle sizes of Laponite, Cloisite‐Na and Kunipia‐F are about 20–30, 70–150, and 300–500 nm, respectively. When ABS was synthesized by the emulsion polymerization in the presence of…
Electronic and thermoelectric properties of pure In 2 O 3 and In 1.5 T 0.5 O 3 ( T = Sc , Y ) alloys including the band gap, the electrical and thermal conductivity, Seebeck coefficient and figure of merit have been investigated using semi-classical Boltzmann transport theory. The calculated results indicated that sub…
Fabrics are typical porous material and can be treated as mixtures of fibers and air. There is no clearly defined boundary and is different from a classical continuum for fabrics. It is complex to proceed with the theoretical analysis of fabric behavior. There are two main reasons One is to be able to calculate the re…
A silicon interposer with an integrated with SrTiO3(STO) thin film capacitor that decreases switching noise in high-speed digital circuits has been developed, along with a process to fabricate it. The process for fabricating the capacitor was optimized to reduce the defect density. The identified optimal process condi…
Abstract Heteroepitaxial growth of well‐aligned ZnO nanorod arrays on GaAs (111) substrates was achieved through electrochemical deposition at low temperature without any buffer layers for the first time. Structural analysis demonstrated the epitaxial orientation relationship of ZnO(0001)//GaAs(111). The rod density w…
