All four known xylazine hydrochloride polymorphous forms were obtained and their relative stabilities were compared directly at three different temperatures. At higher temperatures, it is possible to determine the relative stability of all forms directly by measuring the changes in the composition of the mixtures of t…
Thermal expansion behavior defined as the percentage of dimensional change upon heating for the blend systems of polystyrene/polyethyleneterephthalate has been investigated in this study. General purpose polystyrene (PS) and high impact polystyrene (HIPS) were blended with polyethyleneterephthalate (PET) at a weight r…
In this paper, we present a new tracking control method for holographic digital data storage systems. Holographic data storage systems that use disk media need a different tracking method from those that use optical and hard disk drives. Here, we present the design and implementation of the controller. Due to the inte…
By use of the structural parameters of the single crystal lithium indium orthoborate obtained by Penin et al. (Solid State Sci. 2001, 3, 461-468), from X- ray diffraction data, we present a first-principle study of the electronic structure and the linear optical properties for the novel lithium indium orthoborate Li3I…
Current research and development of high performance concrete, together with study of phenomena that are pertinent to impact resistance, have lead to a new generation of barriers with improved properties to resist impact loads. The paper reviews major properties and mechanisms that affect impact resistance of concrete…
External differential quantum efficiencies were studied for the stimulated emission of thin films of colloidal CdSe/CdS/ZnS nanocrystal quantum dots (NQDs) using the integrating sphere technique. A maximum efficiency of 34% was measured for the stimulated emission in NQDs which far exceeds that for spontaneous emissio…
The 75th multi-authored review volume in the Systematics Association Special Volumes series is based on a 2-day symposium held at the Natural History Museum in London. Many of the most respected specialists in the field of algal systematics attended the symposium and contributed chapters reviewing the current understa…
Three different types of oligothiophene functionalized dihydropyrene photoswitches, (A) 2-naphthoyldimethyldihydropyrenes functionalized at the 4,9-positions with oligothiophenes, (B) benzodimethyldihydropyrenes functionalized at the 4-positions with oligothiophenes and the 10(11)-position with oligothienylcarbonyl gr…
The dynamic, thermal, bending and abrasive loading of thread during sewing process has a negative influence on the properties of sewing threads. In this study, the individual and interactive effect of the number of fabric layers, stitch density and needle size on the loss in tenacity, breaking elongation and initial m…
Abstract A silane‐modified mono‐lacunary Keggin‐type polyoxometalate (POM), (Bu 4 N) 4 [SiW 11 O 39 {(CH 2 CHSi) 2 O}] (SiW 11 CHCH 2 ), was obtained by reaction of vinyltrimethoxysilane with K 8 (SiW 11 O 39 ) in acidic MeCN/H 2 O mixed solutions. Then, the modified polyoxometalate was physically blended with the…
We present 3-D modeling results on resist line-edge-roughness (LER) transfer to underlying films during plasma etching. After generating random fractal resist sidewalls with controlled roughness parameters, we model and contrast the nanoscale roughness phenomena for both resist and underlayer sidewalls in a two-layer…
The $d$-Al-Ni-Co quasicrystal exhibits two crystallographically inequivalent twofold symmetric planes: the {10000} and {12110} surface planes. In particular the twofold symmetric surfaces are very interesting since they are spanned by perpendicular periodic and aperiodic axes. We investigated the (12110) surface of tw…
In order to obtain a criterion of liquid cleaning power, a textile washing test was carried out in water and various organic solvents. Cotton and polyester clothes soiled with particulate, oily and water-soluble contaminants were used. The soiled clothes were cleaned in various liquids with stirring and the detergency…
Solvent microenvironments are formed around individual single-walled carbon nanotubes (SWNTs) by mixing SWNT suspensions with water-immiscible organic solvents. These microenvironments are used to encapsulate the SWNTs with the monomer sebacoyl chloride. Hexamethylene diamine is then injected into the aqueous phase so…
Peptides that undergo a morphological change when exposed to a stimulus have been investigated for their surface and self-assembly properties. Two 15-residue sequences were designed and synthesized for the purpose of determining the role of sequence on surface properties and peptide self-assembly. The KhK (KKKFLIVIGSI…
The synthesis and structure of the pseudotetrahedral, sulfur-rich, high-spin organoiron(II) [phenyltris((tert-butylthio)methyl)borate]Fe(Me), [PhTt(tBu)]Fe(Me), 1, are reported. Low-temperature Mössbauer spectroscopic studies reveal an isomer shift of delta = 0.60(3) mm/s and DeltaE(Q) = 0.00(1) mm/s and an S = 2 grou…
Three novel aqueous soluble fulgimides, trifluoromethyl carboxylic acid indolylfulgimide 4, dicarboxylic acid indolylfulgimide 5, and carboxylic acid indolylfulgimide 6, were synthesized. Both 4 and 5 can switch back and forth between open and closed forms upon illumination with specific wavelengths of light, whereas…
A series of tests was conducted using a reciprocating tribometer to evaluate the tribological performance of a plasma electrolytic oxidation (PEO) treated eutectic aluminium-silicon alloy and was compared with a more conventional nickel-ceramic (Ni-SiC) coating as a reference. The counterpart was a gas-nitrided steel…
The contribution of extreme ultraviolet (EUV) and vacuum ultraviolet (VUV) from a laser-sustained plasma on mass loss phenomenon of fluorinated polymer in the ground-based laser-detonation atomic oxygen (AO) beam source was evaluated. The AO beam and EUV/VUV from an oxygen plasma were separated by a high-speed chopper…
