Among all cancer treatment options, chemotherapy continues to play a major role in killing free cancer cells and removing undetectable tumor micro-focuses. Although chemotherapies are successful in some cases, systemic toxicity may develop at the same time due to lack of selectivity of the drugs for cancer tissues and…
While MnO(2) is a promising material for pseudocapacitor applications due to its high specific capacity and low cost, MnO(2) electrodes suffer from their low electrical and ionic conductivities. In this article, we report a structure where MnO(2) nanoflowers were conformally electrodeposited onto carbon nanotube (CNT)…
Abstract Superhydrophobic and superoleophilic polyester materials are successfully prepared by one‐step growth of silicone nanofilaments onto the textile via chemical vapor deposition of trichloromethylsilane. The successful growth of silicone nanofilaments is confirmed with scanning electron microscopy, energy‐disper…
The recently discovered Fe-pnictide and chalcogenide superconductors display low-temperature properties suggesting superconducting gap structures which appear to vary substantially from family to family, and even within families as a function of doping or pressure. We propose that this apparent nonuniversality can act…
Formation of wall friction force by turbulent oil flow and resulting change of pipe’s stress-strain state are studied. Three-dimensional model of stress-strain state of pipe with internal corrosion defect loaded by internal pressure, friction caused by motion of oil and by temperature is presented. Analysis of main re…
R&D activities on fusion reactor materials in Switzerland focus on (1) the development of advanced metallic materials for structural applications in plasma-facing (first wall, divertor) and breeding blanket components of the future fusion power reactors, in particular oxide dispersion strengthened reduced activati…
The non-perovskite compound LaTi(2)Al(9)O(19) was synthesized and structurally characterized by conventional X-ray powder diffraction and shown to be isostructural with SrTi(3)Al(8)O(19), as confirmed by bond-valence sum calculations. The dielectric properties of LaTi(2)Al(9)O(19) at 1 MHz were measured. The crystal s…
A macroporous polyarylate (PAR) layer was formed on a polyethylene (PE) separator from coating solutions containing PAR, tetrahydrofuran (THF) as the solvent, and various alcohols (or diols) as nonsolvents via a nonsolvent-induced phase separation (NIPS) process. The effects of the nonsolvent molecular structure and i…
Abstract The influence of nanomaterials such as Multi‐Walled Carbon NanoTubes (MWNT) and organoclay (Cloisite 30B) on the physical and mechanical properties of thermoset matrix such as Unsaturated Polyester (UP) resins is investigated. Although styrene containing UP resins have a wide spread application in industry, l…
We study heat generation and transport properties for solids in the presence of arbitrary time-dependent forces. Using a nonequilibrium Green's function (NEGF) approach we present an exact analytical expression of heat current for the linear system. We found that the current can be expressed in terms of the displaceme…
In 1998, Persily published a review of commercial and institutional building airtightness data that found significant levels of air leakage and debunked the myth of the airtight commercial building. Since that time, the U.S. National Institute of Standards and Technology (NIST) has maintained a database of measured ai…
Results are presented from a direct comparison of 2,7-diphenylcarbazole (DPC) nanofibers fabricated in the form of parallel to the surface plane aligned arrays by means of organic molecular beam deposition (OMBD) and fabricated in the form of normal to the surface aligned arrays by solution-assisted wetting of porous…
Stearic acid (CH3(CH2)16COOH) was treated with Ar and Ar-O2 (10%) pulsed DC discharges created by a cathode-anode confined system to elucidate the role of oxygen in plasma cleaning. The treatment time (5 to 120 minutes) and plasma gas mixture (Ar and Ar-O2) were varied, and the results showed that the mass variation o…
Abstract Nanoparticles composed of Eu‐complex, Eu(TTA) 3 Phen, and polystyrene (PS) were successfully synthesized through an improved solvent swelling method. The unstable Eu(TTA) 3 Phen could be protected by the hydrophobic shell of PS nanoparticles. This method is very appropriate to embed unstable luminescent molec…
Abstract Based on mechanical models, the creep behavior of carpet yarns after dynamic loading was investigated. For prediction the creep elongation, the frequently used mechanical models reported in the literature were analyzed. The mechanical models which were used in this article were: standard linear model, four‐el…
We have successfully synthesized multicomponent Mg‐based nano‐quasicrystals (nano‐QCs) through a simple route by using a water‐cooled wedge‐shaped copper mould. Nanoscale QCs are prepared directly on tip of wedge‐shaped castings. The further study shows that nano‐QCs in the Mg 71 Zn 26 Y 2 Cu 1 alloy show well microha…
A large magnetoresistance (MR) effect was observed in the layered compounds NdCoAsO and SmCoAsO, in which ferromagnetically ordered itinerant electrons of Co are sandwiched by localized 4$f$ electrons of $L{n}^{3+}$ below ferromagnetic-antiferromagnetic transition (FAFT) temperature ${T}_{\mathrm{N}}$ as observed in o…
SUMMARY Finite elements providing a C 1 continuous interpolation are useful in the numerical solution of problems where the underlying partial differential equation is of fourth order, such as beam and plate bending and deformation of strain‐gradient‐dependent materials. Although a few C 1 elements have been presented…
Abstract Polymer/carbon nanotube (CNT) nanocomposites have received much attention recently. In this study, we attempt to enhance the electrical conductivity of polyimide (PI) by variously modifying multiwall carbon nanotube (MWNT). We report the successful synthesis of PI/MWNT composite films using a blending process…
Abstract A new melt‐processable PTFE material is presented and characterized that provides new and economical solutions in polymer technology while bridging the gap between perfluorinated PTFE and fluorothermoplastic materials such as perfluoroalkoxy resins. Thermal transitions, MW and MWD, and microstructures of the…
