The method described by this Test Guideline provides information that allows hazard assessment for short-term exposure to a test article by inhalation, and allows the substance to be classified according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). The test method is based on a…

Nonresonant anisotropic metamaterials (AMMs), such as nanotube arrays, can be applied to achieve broadband absorption of electromagnetic (EM) waves. However, the AMMs should be very thick ($\ensuremath{\sim}1000$ wavelengths) to attain high absorption. Here, we propose that using a slanted or corrugated metallic mirro…
The multilayers of poly(L-lysine) (PLL) and hyaluronic acid (HA) were constructed by alternating deposition of PLL at high pH and HA at low pH. The exponential growth of the multilayer was proved to be amplified by increasing the pH difference between the two deposition solutions. The exponential growth multilayers of…
Dendrimer-like poly(ethylene oxide)s (PEOs) were synthesized through a semicontinuous process based on the anionic ring-opening polymerization (AROP) of ethylene oxide (EO), followed by AROP of a mixture of glycidol (G) and propylene oxide (PO). Glycidol was used as branching agent generating two hydroxyl groups after…
Reaction of the divacant polyoxometalate K(8)[gamma-XW(10)O(36)] (X = Si, Ge) with two equivalents of the metal-nitrido precursor Cs(2)[Ru(VI)NCl(5)], at room temperature in water, produces K(2)(Me(2)NH(2))(2)H(2)[gamma-XW(10)O(38){RuN}(2)], X = Si (DMA-1 a) or Ge (DMA-1 b). The X-ray crystal structures of both comple…
Lithium propanoate and pentanoate were characterized by DSC, single crystal and powder XRD and FTIR and impedance spectroscopies. Lithium propanoate presents a solid-to-solid transition (SII-SI) at T(ss) = (549.1 +/- 0.7) K on first heating that varies on the second and next ones, followed by a fusion at T(f) = (606.1…
It has been well documented that single-crystal stable-temperature (ST)-cut quartz substrates can horizontally align single-walled carbon nanotubes (SWNTs) along the x direction ([100]) during catalyzed chemical vapor deposition. It has been suggested that alignment is due to either surface-guided growth along step ed…
An in-depth study of the physical and electrical properties of Si-nanocrystal-based MOSLEDs is presented. The active layers were fabricated with different concentrations of Si by both ion implantation and plasma-enhanced chemical vapour deposition. Devices fabricated by ion implantation exhibit a combination of direct…
Jute fabrics (hessian cloth) reinforced polypropylene (PP) matrix composites were fabricated by compression molding. Jute fabrics and matrices were irradiated with gamma and UV radiation at different doses. Mechanical properties of irradiated jute fabrics and matrices based composites were found to increase significan…
Glass fiber (GF)-reinforced biodegradable poly(propylene carbonate) (PPC) composites were prepared by melt blending. The effects of reinforcement on the mechanical, thermal, and morphological properties of the PPC/GF composites were investigated. The mechanical properties of the composites were found to be improved ob…
Validated by ab initio simulations on the spontaneous polarization, the molecular dynamics method is used to investigate the size effect on the polarization distribution, hysteresis behaviors and Curie temperatures of BaTiO3 nanowires. A quasi-axisymmetric radial distribution of polarization in the cross-section plane…
Polarizable interaction potentials, parametrized using ab initio electronic structure calculations, have been used in molecular dynamics simulations to study the effect of cation composition on the ionic conductivity in the Zr(2)Y(2)O(7)-Y(3)NbO(7) system and to link the dynamical properties to the degree of lattice d…
A facile one-pot synthesis of nitriles starting with aldehydes has been developed employing hydroxylamine hydrochloride in dimethylsulfoxide at 100°C.
This article studies the forced vibration of the carbon nanotubes (CNTs) using the local and the non-local Euler—Bernoulli beam theory. Amplitude ratios for the local and the non-local Euler—Bernoulli beam models are given for single- and double-walled CNTs. It is found that the non-local models give higher amplitudes…
This paper demonstrates a highly sensitive humidity sensor based on carbon nanotube and poly (dimethyldiallylammonium chloride) composite films. The composite film is deposited between interdigitated electrodes on a${\rm Si/SiO}_{2}$substrate through layer-by-layer self-assembly technique. The resistance stability of…
The formation of carbonaceous deposits on Pt(111) surfaces and Pt nanoparticles has been studied using suitable models and density-functional calculations. The study addresses a broad range of processes, from the very first stage of carbon deposition up to a final building of graphene monolayers (ML) defined as a 1:1…
We present a general approach to growing ZnO nanowires on arbitrary, high melting point (above 970 degrees C) substrates using the vapor-liquid-solid (VLS) growth mechanism. Our approach utilizes the melting point reduction of sufficiently small (5 nm diameter) Au particles to provide a liquid catalyst without substra…
CdTe nanorod arrays on ITO have been demonstrated using a catalyst-free thermal evaporation method. Despite the stacking faults observed in the nanorods, they show intense near band edge emission at ∼1.5 eV with a narrow full width at half-maximum of 79 meV and negligible deep-level emission during the room temperatur…
In this paper, the physicochemical characteristics and mineral transformation behavior of three crop straw ashes (rice straw, wheat straw, and cotton straw) were investigated using ICP-AES, XRF, SEM-EDS, XRD, and ash fusion point analyzer. It was found that these ashes had quite high content of alkali metals (especial…
