An inverse problem of bilayer textile thickness determination in dynamic heat and moisture transfer is presented satisfying the heat–moisture comfort level of human body. Heat and mass transfer law in bilayer textiles is displayed by proving the existence and uniqueness of solution to the coupled partial differential…
This study reports on the fabrication of vertically aligned carbon nanotubes localized at specific sites on a growth substrate by deposition of a nanoparticle suspension using inkjet printing. Carbon nanotubes were grown with high yield as vertically aligned forests to a length of approximately 400 μm. The use of inkj…
A biodegradable planting container made with rice straw and starch adhesives modified by polyvinyl alcohol was studied in this paper. The effect of heat treatment and polyamide resin on the properties of planting containers was investigated. The physical property and biodegradability were characterized by means of hyg…
The thermal transport properties of ultra-scaled Si nanowires are investigated in the presence of anharmonic phonon-phonon scattering and surface roughness. These two effects are either treated simultaneously (accurate method) or combined together through Matthiessen's rule (approximation). In both cases, an advanced…
Strongly alkaline electrolyzed water (SAEW) was used as a sericin swelling agent for silk reeling from cocoons of the silkworm Bombyx mori. Tap water was electrolyzed with a laboratory-made combined water electrolyzer to generate SAEW with pH 11.50. The hardness of SAEW was 30% less than that of the tap water, whereas…
The synchrotron high-energy x-ray diffraction was used to trace directly the structural evolution of polycrystalline DyCo2, one of RT2 (R = rare earth, T = Co, Fe) compounds with Laves phase, as a function of temperature and magnetic field. When the DyCo2 compound was zero-field cooled down below TC, the high temperat…
Magnetotransport experiments on ABC-stacked suspended trilayer graphene reveal a complete splitting of the 12-fold degenerated lowest Landau level, and, in particular, the opening of an exchange-driven gap at the charge neutrality point. A quantitative analysis of distinctness of the quantum Hall plateaus as a functio…
The inner C-benzyl- and C-p-xylyl-substituted cobalt(II) complexes of a 2-N-substituted N-confused porphyrin were synthesized from the reaction of 2-NCH2COOCH2C6H5NCTPPH (1) and CoCl2·6H2O in toluene (or p-xylene), and the structures were revealed by single-crystal X-ray analysis.
Crednerite glass-ceramic material (CuMnO2) has been investigated for the first time as a hydrogen storage candidate. The average gravimetric capacity is about 16 g H2/kg and about 50 g H2/kg of CuMnO2 at 473 and 573 K respectively under a pressure up to 20 bars. The hydrogen adsorbed capacity (weight percent) of CuMnO…
The EPR spectra of Gd 3+ ion replacing Y 3+ or rare‐earth (RE) ions in aluminum borates REAl 3 (BO 3 ) 4 (RE = Y 3+ , Eu 3+ , Tm 3+ ) have been studied. The spin‐Hamiltonian parameters of an impurity Gd 3+ ion in these crystals were determined. The basic atom coordinates in the structure of TmAl 3 (BO 3 ) 4 crystal ha…
ABSTRACT Three surface modifiers, namely, aminopolyether (D2000), phenyl isocyanate, and poly(ethylene glycol) (PEG800), which have different affinities to the hard and soft segments in polyurea, were used to synthesize functionalized graphite oxides (GO). The PEG800‐modified (PEG800‐GO) and phenyl isocyanate‐modified…
Charging of insulating substrates is a common problem during Electron Beam lithography (EBL), which deflects the beam and distorts the pattern. A homogeneous, electrically conductive, and transparent graphene layer is used as a discharge layer for EBL processes on insulating substrates. The EBL resolution is improved…
To control the thermal shrinkage of poly(lactic acid) draw-textured yarns, the annealing effects on structural changes and thermal shrinkage were investigated. Specifically, annealing temperatures of 100 and 160°C and annealing times of 10–50 min per every 10 min were investigated. Differential scanning calorimetry th…
Recently, a metastable bixbyite-type polymorph of vanadium sesquioxide V 2 O 3 has been synthesized from vanadium trifluoride. During the preparation, a very low oxygen partial pressure was necessary to prevent oxidation to higher valent vanadium oxides. In order to provide a quantitative description of the oxidation…
Abstract The magnetic properties of the layered lanthanide hydroxide Dy8(OH)20Cl4·6H2O were studied. Below 5 K, slow magnetic relaxation was observed even in the absence of an external field, with a blocking temperature of 3 K and an energy barrier of 36.1 K, a behavior characteristic of single‐molecule magnets.
A hybrid complex composed of an anionic conjugated polyelectrolyte (PFB-SO3Na) and a cationic phosphorescent Ir(III) oligomer is formed through electrostatic interaction by simple physical mixing in aqueous media. Due to their opposite charges and their effective spectral overlap, fluorescence resonance energy transfe…
A straight synthetic route to fabricate hybrid nanocomposite films of well-dispersed CdS nanocrystals (NCs) in poly[2-methoxy-5-(2'-ethyl-hexyloxy)-1,4-phenylene vinylene] (MEH-PPV) is reported. A soluble cadmium complex [Cd(SBz)2]2·MI, obtained by incorporating a Lewis base (1-methylimidazole, MI) on the cadmium bis(…
Previous studies of the dynamics of hydrated proteins had shown a feature resembling an exceptionally broad glass-softening endotherm. Its onset temperature, denoted as T(g), was indefinable in one calorimetric study of hydrated lysozyme and was in the 148-218 K range in another study, depending upon hydration. Other…
ABSTRACT A new type of self‐crosslinking latex film was prepared from hydrogenated carboxylated nitrile‐butadiene rubber (HXNBR) latex by diimide reduction. The properties of the HXNBR rubber, including film surface morphology, physical properties, thermal stability and ageing properties, were investigated. FTIR spect…
In this paper, we study the static polarization in ABC-stacked multilayer graphene. Since the density of states diverges for these systems if the number of layers exceeds three, screening effects are expected to be important. In the random phase approximation, screening can be included through the polarization. We der…
