Abstract Depending on the morphology of the material and applied voltage frequency, three kinds of electrical trees can exist in cross‐linked polyethylene (XLPE) cable insulation, which are conducting, non‐conducting, and mixed trees with different growth mechanisms. It is suggested that when the needle is inserted in…
Abstract Skim natural rubber latex is a protein‐rich byproduct obtained during the centrifugal concentration of natural rubber latex. Skim latex has a very low dry rubber content (4–8%), and the rubber particles are smaller in size. It has a higher proportion of nonrubber solids, which are mostly proteinaceous in natu…
The flame retardancy, thermal degradation, combustion behaviors and mechanical properties of a pure polypropylene (PP)/thermoplastic polyurethane (TPU) blend, and PP/TPU blends containing flame retardants, ammonium polyphosphate (APP), pentaerythritol (PER), and melamine cyanurate (MCA), as well as the surface-treated…
Challenges and issues with the scaling of low-k/Cu interconnects in ultra-large-scale integration (ULSI) devices are reviewed, and the performance of interconnects is featured by considering the effect of the resistance and capacitance per unit interconnect length or the minimum grid length. The grid-scaled resistance…
Cumulen oder Polyin? Die Synthese und kristallographische Analyse einer Serie von Polyinen mit tert-Butyl-Endgruppen und bis zu 20 sp-hybridisierten Kohlenstoffatomen ist erstmals gelungen. Die Strukturdaten weisen eine deutliche Verringerung der Bindungslängenalternanz mit zunehmender Polyinlänge auf, jedoch scheint…
We have measured the Raman scattering spectrum and the carrier-to-noise ratio (CNR) simultaneously during readout from a super-resolution readout (SRR) optical disk utilizing an antimony resolution enhancing layer. Both the Stokes and anti-Stokes spectrum of the antimony A 1g mode at ±150 cm -1 were observed at differ…
Abstract Multilayer hyperbranched polyimide/polyhedral oligomeric silsesquioxane (POSS) nanocomposites were synthesized by the reaction of a bromide‐hyperbranched polyether/POSS and a main‐chain polyimide containing hydroxyl‐functional groups. The first layer was formed through the direct reactions of the main‐chain h…
Poly(p-dioxanone) (PPDO) is a useful biomaterial and potential ecomaterial due to its biodegradability and good mechanical properties. Like other aliphatic polyesters, however, it has a low crystallization rate and low melt strength; it is difficult to produce thin films from it by blown film processing. In this work,…
Abstract The complex dynamic behavior of a diesel particulate filter (DPF) system during the regeneration process can be well predicted by detailed numerical simulation. Simulation studies for diesel oxidation catalyst (DOC) and catalyzed DPF (CDPF) based on detailed kinetic experiments are presented for the relevant…
Abstract The mechanical properties, flame retardancy, hot‐air ageing, and hot‐oil ageing resistance of ethylene‐vinyl acetate rubber (EVM)/hydrogenated nitrile‐butadiene rubber (HNBR)/magnesium hydroxide (MH) composites were studied. With increasing HNBR fraction, elongation at break and tear strength of the EVM/HNBR/…
Abstract Monolithic catalysts were prepared by washcoating an alumina sol and then impregnating Cu‐Mn‐Ag mixed oxides onto cordierite substrates. The effects of the preparation parameters including the Ag/Cu/Mn ratio, the total amount of active phase and the loading of washcoat, and the reaction conditions, e.g., the…
Abstract Raman and IR spectra of Bi 2 W 2 O 9 , the m = 2 member of the cation‐deficient Aurivillius phase, have been measured. The obtained spectra are discussed using the factor group approach for the orthorhombic Pna 2 1 ( C 2 v 9 ) space group. The results are compared with those obtained for Bi 2 WO 6 and some m…
Abstract Ethylene diamine polyesteramide (Ed‐PEA) was synthesized from N, N ‐bis (2‐hydroxy ethyl) linseed oil fattyamide and ethylene diamine tetra acetic acid through condensation polymerization. It was further treated with toluylene 2,4‐diisocyanate (TDI) in different weight percentage to obtain urethane‐modified p…
Fluorescence resonant energy transfer (FRET) has been clearly demonstrated between CdSe/ZnS type I quantum dots and CdSe/ZnTe type II quantum dots by photoluminescence, time-resolved photoluminescence (TRPL), and photoluminescence excitation (PLE) measurements. The result of PLE experiment provides us concrete evidenc…
The solvothermal synthetic system Ln/Sb/Se (Ln = La, Eu) was investigated in different ethylene polyamines, and a series of lanthanum and europium selenidoantimonates [La(en)(2)(dien)(eta(2)-SbSe(4))] (Ia), [La(dien)(2)(mu-eta(1),eta(2)-SbSe(4))] (Ib), [La(trien)(2)(H(2)O)]SbSe(4) (Ic), [La(en)(trien)(mu-eta(1),eta(2)…
Using muon-spin rotation, we studied the in-plane (${\ensuremath{\lambda}}_{ab}$) and the out of plane (${\ensuremath{\lambda}}_{c}$) magnetic field penetration depth in ${\mathrm{SrFe}}_{1.75}{\mathrm{Co}}_{0.25}{\mathrm{As}}_{2}$ (${T}_{c}\ensuremath{\simeq}13.3\text{ }\text{ }\mathrm{K}$). The penetration depth ani…
In this work we show a theoretical study of the electronic and transport properties of superlattices formed by a periodic structure of vacancies (antidots) on graphene nanoribbons. The systems are described by a single-band tight-binding Hamiltonian and also by ab initio total energy density-functional theory calculat…
We present density functional theory (DFT) calculations and soft x-ray spectra (soft x-ray spectroscopy and x-ray photoelectron spectra) measurements of single-crystal ${\text{CaFe}}_{2}{\text{As}}_{2}$. The experimental valence-band spectra are consistent with our DFT calculations. Both theory and experiment show tha…
Abstract In this study, three different carbon fillers (Thermocarb TC‐300 synthetic graphite, Ketjenblack EC‐600 JD carbon black, and Hyperion Catalysis International's FIBRIL™ carbon nanotubes) were added to a polypropylene matrix to produce single filler composites with filler concentrations of up to 80 wt % synthet…
Abstract Polyamide 6 (PA6) is modified with a nanoclay (NC), Cloisite 30B and/or a flame retardant (FR), OP1311. The thermal decomposition of pure PA6 and PA6 nanocomposites is done by thermogravimetric analysis (TGA). The decomposition products from TGA in nitrogen and air are analysed online by Fourier transform inf…
