In a two-step method, carbon nanotubes, inorganic nanowires, or graphene sheets are connected between two anchor points to form nanomaterial air bridges. First, a recently developed method of forming directionally oriented polymer nanofibers by hand-application is used to form suspended composite polymer-nanomaterial…
As a new technology, supercapacitor can attain greater energy density than those of conventional capacitors and greater power density than those of batteries. As a result, supercapacitors may become an attractive power solution for an increasing number of applications. In this paper, after a brief introduction of supe…
Al–N codoped zinc oxide films were prepared using a radio-frequency magnetron cosputtering system at room temperature. AlN and ZnO materials were employed as the cosputtered targets. The as-deposited cosputtered films at various theoretical atomic ratios [Al∕(Al+Zn)at.%] showed n-type conductive behavior in spite of t…
The structure of the amorphous perfluorinated polymer Teflon AF 2400 and other structurally close perfluoropolymers was studied by means of a quantum chemistry method. The electronic and structural characteristics of the repeating unit and polymer models with ten and nine monomer units were obtained. It was found that…
Abstract Summary : In this study, two different routes were chosen which are expected to influence the elongational viscosity and, thus, the foaming behavior of polypropylene (PP). Electron irradiation of a linear PP was performed at room temperature using different doses. Enhanced long‐chain branching was observed wi…
The crystal structure of parageorgbokiite, β-Cu 5 O 2 (SeO 3 ) 2 Cl 2 , a new mineral species from the fumaroles of the Great Fissure Tolbachik eruption, in the Kamchatka Peninsula, Russia, has been solved from single-crystal X-ray-diffraction data by direct methods and refined to R 1 = 0.032 for 1388 unique reflectio…
Radial-easy-magnetized Ni nanowire arrays have been fabricated by direct current (dc) electrodeposition in pores of anodic aluminum oxide (AAO) templates. The most probable length value of grains' long axes in nanowire is 7.5 nm. These small grains with random crystallographic direction are the main reason for Ni nano…
Abstract In this study, a comparison is made on the models available to predict the flexural modulus of structural polymer foams. Skin thickness and density profile in the core zone are taken into account to better relate foam morphology with mechanical response. It was found that including skin thickness is not suffi…
Abstract Surface temperature measurements are crucial in many applications; one promising approach is the use of thermographic phosphors. The temperatures of surfaces coated with such a material can easily be detected by measuring and evaluating the luminescence. In the present study, the CVD of chromium‐doped aluminu…
A conceptually simple method to calculate local and average pressure tensors in simulations of molecular systems with discrete particles is presented. The pressure originates from the linear momentum of the particles as well as from n-body interactions between the particles, and consists of one additive contribution f…
In this paper we consider a Cahn–Hilliard model endowed with the Wentzell boundary condition, which arises from the study of spinodal decomposition in binary mixtures confined to a bounded domain with permeable wall. Under the assumption that the nonlinearity is analytic with respect to the unknown dependent function,…
We created artificial proteins that contained repeats of a short peptide motif, Asn-Gly-Asx. In nature this motif is repeated within shell proteins as an idiosyncratic domain, while in vitro it has been shown to suppress calcification. The motif was embedded within peptide sequences that did or did not have the abilit…
Relationship between Chemical Structure and Helical Twisting Power in Optically Active Imine Dopants Derived from (R)-(+)-1-(1-Naphthyl)ethylamine, Fukuda, Kaoru, Suzuki, Hideyuki, Ni, Jin, Tokita, Masatoshi, Watanabe, Junji
To alleviate the problems associated with current copper interconnect technology, multi-walled carbon nanotubes (MWCNTs) have been proposed as a potential solution for on-chip communication in VLSI applications. In this paper, we develop an equivalent RC circuit model for MWCNT interconnect that captures both DC condu…
Abstract We present the synthesis of hyperbranched polymer grafted zinc oxide (ZnO) hybrid nanoparticles by self‐condensing vinyl polymerization (SCVP) via surface‐initiated atom transfer radical polymerizations (SI‐ATRP) from ZnO surfaces. ATRP initiators were covalently linked to the surfaces of ZnO particles, follo…
Pauflerite, β-VO(SO 4 ), is a new mineral species from the fumaroles of the Great Fissure Tolbachik eruption (GFTE), Kamchatka Peninsula, Russia. It was found in 1977 in the first cinder cone of the North breach of the GFTE. The mineral occurs as light green prismatic crystals up to 0.1 mm in length, associated with s…
Abstract Carboxymethyl‐chitosan (CMCS)/poly(vinyl alcohol) (PVA) blend film was studied for an application as a coating material in the site‐specific drug delivery system. Films were prepared by blending varying amounts of 4 wt% CMCS with 4 wt% PVA, casting and drying at 50°C for 24 h. The cross‐sectional SEM microgra…
The role of (Al,Si) disorder in the kinetics of albite dissolution is explored through parameterized Monte Carlo methods. Two dissolution mechanisms multilayer leaching and single-layer retreat. were tested on 48 albite test configurations. In simulations involving multilayer leaching, dissolution rates increased with…

Catalytically enhanced growth of ZnMnTe diluted magnetic semiconductor nanowires by molecular beam epitaxy is reported. The growth is based on the vapor-liquid-solid mechanism and was performed on ( X-ray diffractometry, scanning and transmission electron microscopy, atomic force microscopy, photoluminescence spectros…
