We present a modeling scheme to analyze cagelike silica mesoporous crystals based on in situ X-ray diffraction (XRD) data collected during gas adsorption-desorption (physisorption) processes. Nitrogen physisorption on a silica mesoporous crystal of SBA-16 was directly monitored by using synchrotron in situ powder XRD…
Predictability of the bending rigidity of cotton plain-woven fabrics from their structural parameters has been investigated using an adaptive neuro-fuzzy inference system (ANFIS) approach. A set of cotton grey fabrics meant for apparel end use was desized, scoured, and relaxed. The fabrics were then conditioned and te…
The use of ex vivo-derived scaffolds as vascular conduits has shown to be a clinically valid approach to repair or bypass occluded vessels. Implantation of allogeneic tissue grafts requires careful processing to lower immunogenicity and prevent bacterial infection. However, the mechanical/chemical treatments used to p…
Abstract Samples of PVC foils are exposed to an early afterglow of gaseous plasma created by an electrode‐less RF discharge in predominant H‐mode using Ar, H 2 and O 2 gases. Sample temperature is measured with a pyrometer while the presence of reaction products is determined with an optical spectrometer. The temporal…
Abstract A comprehensive study of the magnetocaloric effect (MCE) in the Mn 2 ‐[Nb(CN) 8 ] molecular magnet with a two‐step magnetic sponge behavior is reported. The structural transformations provoked by dehydration bring about an increase in the magnetic ordering temperature ( T c ) from 43 K through to 68 K and up…
A novel bilayer superhydrophobic film was constructed on Cu substrate by a simple multi‐step process. First, (3‐mercaptopropyl) trimethoxysilane (MPTMS) molecules were self‐assembled onto the pre‐etched Cu surface via covalent bonding followed by hydrolysis and condensation, then 1H, 1H, 2H, 2H‐perfluorodecyltrichloro…
In this paper, a 3-D methodology for the overheating hazard assessment on transformer covers based on electromagnetic analytical formulation linked with thermal finite element method is presented. The objective is to offer a practical tool to compute the temperature distribution and to localize the hot spots on transf…
A generic history-penalized metabasin escape algorithm that contains no predetermined parameters is presented in this work. The spatial location and volume of imposed penalty functions in the configurational space are determined in self-learning processes as the 3N-dimensional potential energy surface is sampled. The…
Hpn, one of Helicobacter pylori's nickel-accessory proteins, is an amazingly peculiar protein: Almost half of its sequence consists of polyhistidyl (poly-His) residues. Herein, we try to understand the origin of this naturally occurring sequence, thereby shedding some light on the bioinorganic chemistry of Hpn's numer…
In high-resolution resonant inelastic x-ray scattering at the Ti L edge of the charge-density-wave system 1T-TiSe(2), we observe sharp low energy loss peaks from electron-hole pair excitations developing at low temperature. These excitations are strongly dispersing as a function of the transferred momentum of light. W…
We proposed a novel white-light-emitting diode (LED) using the hybridization of quantum dots (QDs) blended with poly(9, 9-dioctylfluorenyl-2, 7-diyl) (PFO) as the white emissive layer and poly(N-vinylcarbazole) (PVK) blended with poly(N, N' -bis (4-butylphenyl)-N, N'-bis(phenyl) benzidine (poly-TPD) as the hole transp…
It has been reported that the surface pressure-area isotherm of poly(D,L-lactic acid-ran-glycolic acid) (PLGA) at the air-water interface exhibits several interesting features: (1) a plateau at intermediate compression levels, (2) a sharp rise in surface pressure upon further compression, and (3) marked surface pressu…
In the Bosch-proprietary “advanced porous silicon membrane process”, porous silicon (PSi) is used for the first time in high-volume industrial production of microelectromechanical devices. Nanoporous silicon acts as an auxiliary layer during manufacturing of monolithically integrated pressure sensors in a mixed-signal…
Abstract When a DC voltage is applied to an insulating spacer, the electric field distribution around it is determined by the resistivity of the material. Consequently, charges are accumulated on the surface of the insulator, and its breakdown voltage may become low. In this paper, the charge density distribution of t…
The mechanical properties of ZrB2–30 wt-%SiC ultra high temperature ceramic composites have been studied. The composite was processed by hot pressing at 2100°C, 30 MPa and 45 min dwell time to achieve a good densification. Young’s modulus, single edge V notch beam fracture toughness, hardness, stress–strain deformatio…
In this paper, we performed a multiscale study on the hydrogen storage capacity of Li-doped phthalocyanine covalent organic frameworks (Li-doped Pc-PBBA COF). We combine the first-principles studies of hydrogen adsorption and migration energies with the kinetic Monte Carlo simulations of hydrogen adsorption, diffusion…
In this paper, integrated temperature sensors based on active nanocomposite planar waveguides are presented. The nanocomposites consist of cadmium selenide (CdSe) and cadmium telluride (CdTe) quantum dots (QDs) embedded in a polymethylmethacrylate (PMMA) matrix. When the samples are heated in a temperature range from…
A new and simple kind of heterostructure nanoelectronics, which are free of metal electrodes, is constructed by a boron nitride nanoribbon (BNNR) seamlessly connected between two pieces of graphene nanoribbons (GNRs). The electron transport properties of devices based on such GNR-BNNR-GNR heterostructures are systemat…
POM and luminescence: The first charge transfer intercluster crystal has been synthesized by using [Ag62S13(StBu)32]4+ as the cation and Mo6O192− as the anion. Its luminescence behavior is controlled by the electron accepting ability of the polyoxometalate (POM). The emission quenched by the charge transfer could be t…
Bent-shaped rigid-core molecules with flexible chiral dendrons grafted to the outer side of the bend were synthesized and characterized by circular dichroism, differential scanning calorimetry, X-ray scatterings, and transmission electron microscopy in solution and the solid state. The bent aromatic rods based on hept…
