Extremely low field time dependent dielectric breakdown measurements were performed on single damascene structures with 90 and 50 nm ½ pitch integrated in a porous low-k material (k=2.5). We found with statistical significance that the E-model and the √E-model were too conservative to extrapolate our high field data t…
Low-frequency noise characteristics for carbon-nanotube (CNT)/cellulose composite paper were experimentally investigated. The measured low-frequency noise exhibited 1/ f characteristics and can be explained by Hooge's empirical law. Large noise coefficients suggested that CNT–CNT junctions, not the CNTs themselves, ar…
The crystal structure and magnetic properties of melt spun SmCo7−xMx (M=Ta, Cr, and Mo; x=0–0.6) ribbons have been investigated. Based on x-ray diffraction analysis, it is found that a pure TbCu7-type structure is formed in the melt spun SmCo7−xTax (x=0–0.3) ribbons, while minor amount of additional 2:17 phase appears…
A Si--H functionalized phenyl-bridged periodic mesoporous organosilica [H-PMO(Ph)] is synthesized via a surfactant-directed assembly approach. Pd nanoparticles are then immobilized onto the PMO catalyst [Pd/H-PMO(Ph)] by a Si--H in situ reduction method. The Ullmann reaction, in water as medium, is used to investigate…
Abstract Poly( L ‐lactic acid) (PLLA) has good biocompatibility, biodegradability and physical properties. However, one of the drawbacks of PLLA is its brittleness due to the stiff backbone chain. In this work, a largely improved tensile toughness (extensibility) of PLLA was achieved by blending it with poly(ε‐caprola…
Sugarcane bagasse is divided into two major components. They are pith and rind. Pith is the inner part of sugarcane bagasse while rind is the outer part of it. In this study, the flexural properties of pith reinforced poly (vinyl chloride) composites were compared to that of rind composites with the same matrix in var…
High-filler-content paper is a growing research and development opportunity in papermaking. These new products must address traditional paper product properties while providing papermakers with distinct product platform benefits. Over the past decade, a research team involving researchers from the Institute of Paper S…
This article describes some possibilities opened by sugar-derived structures in the field of new materials. We selected commercially available structures, mannitol M, sorbitol S, dulcitol D, which are low cost by-products of industrial sugars used for food. These structures present OH functions regularly distributed o…
Porous silicon carbide (SiC) ceramics are produced using carbon matrices derived from natural wood. Such material is especially promising as it is environmentally friendly with attractive physical properties, including a high level of biocompatibility, chemical inertness, and mechanical strength. We have developed a f…
Details of two new small marine taxa of the genus Cocconeis Ehrenberg are described; C. pottercovei sp. nov. and C. pinnata var. matsii var. nov., which were observed as epipelic and epiphytic in Potter Cove, King George Island, Antarctica. Descriptions are based on both light and scanning electron microscope observat…
This paper describes an overview of a new meshless solution procedure for calculation of one-domain coupled macroscopic heat, mass, momentum and species transfer problems as well as phase-field concepts of grain evolution. The solution procedure is defined on the macro [1] as well as on the micro levels [2] by a set o…
Feasibility of step coverage (SC) by supercritical fluid deposition (SCFD) of Cu was evaluated using a finite element method (FEM) simulation with experimentally estimated kinetics and transport properties of the precursor. This SC by Cu-SCFD was compared with that by chemical vapor deposition (CVD). SCFD showed super…
Despite aggressive multimodal strategies, the prognosis in patients affected by primary brain tumors is still very unfavorable. Glial tumors seem to be able to create a favorable environment for the invasion of neoplastic cells into the cerebral parenchyma when they interact with the extracellular matrix via cell surf…
The cross section of two alternating concentric double silica-gold nanoshell (DSGNS) is obtained as a function of wavelength. Numerical calculations show that two alternating concentric DSGNSs display two separated scattering peaks that the intensity and position of the scattering peaks depend on two gold shells thick…
Phase coexistence phenomena related to direct and reverse martensitic transformation have been studied in melt spun ribbons of the magnetic shape memory alloy Mn49.5Ni40.4In10.1. For magnetic fields above 10 kOe martensitic transformation undergoes a progressive kinetic arrest. The metastable character of the field-co…

Abstract The sorption kinetics for birch black liquor xylan onto unbleached softwood kraft fibers at industrial relevant process conditions was investigated. The impact of process conditions on total sorption and rate was studied. It was found that an unbleached fiber can increase its weight up to 40% by sorption of x…
The effect of interstitial nitrogen on the phase transition and magnetocaloric behavior of MnAs1−xSixNδ (x=0.03, 0.06, and 0.09) is investigated. The interstitial nitrogen atoms cause the step-scanned x-ray diffraction peaks to shift toward lower angles and lower the Curie temperature, whereas silicon addition increas…
Red, green, and blue dyes were doped to polymer dispersed liquid crystal (PDLC) films for flexible display applications. Dichroic dye-doped liquid crystal droplets had a bipolar configuration. The E7–DG6071–dye composition showed better chromaticity data than other compositions. The small-particle-size red-dye-doped P…
Magnetoresistance (MR) and magnetocaloric effect around martensitic transformation were investigated in a Ni45Co5Mn36.5In13.5 alloy. The martensitic temperature (TM) locates at ∼260 K. An external magnetic field can drive TM to a lower temperature at a rate of ∼9.2 K/T. Associated with the field-induced metamagnetic b…
