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…
Single crystals of Ln(4)Na(2)K(2)M(2)O(13) (Ln = Nd, Sm, Eu, Gd; M = Nb, Ta) were grown out of a reactive high temperature hydroxide melt. The structures were determined by single crystal X-ray diffraction. Ln(4)Na(2)K(2)M(2)O(13) crystallizes in the monoclinic space group C2/c in which niobium and tantalum are locate…
Based on the main physical processes of secondary electron emission from metals, the relation that the product of the number of secondary electron released per primary electron at high incident electron energy and the (n-1)th power of incident energy of primary electron is equal to constant C was deduced, where n is t…
Abstract The effects of molecular weight (MW) of isotactic polypropylene (iPP), the content of β ‐PP, the size of its spherulites and the morphology of its α ‐phase and β ‐phase ( α ‐ and β ‐PP) on the impact strength, with different contents of β ‐nucleating agent, were investigated by two ways. The results show that…
We studied the spatiotemporal dynamics of a new system consisting of sulfide ions (outer electrolyte) diffusing into an organic gel (gelatin) containing mercaptoethanol-capped cadmium ions (inner electrolyte). The product, cadmium sulfide, exhibits a faint yellow transparent propagating front starting at the gel-outer…
Abstract Reaction of nickel(II) thiocyanate and pyridazine (pdz) as organic spacer ligand leads to the formation of the ligand‐rich 1:2 (1:2 = metal to ligand ratio) trinuclear nickel(II) complex of composition [Ni 3 (NCS) 6 (pdz) 6 ]. Depending on the reaction solvent, different polymorphic modifications are obtained…
This article presents the compressive mechanical response at low strains for a collection of polyethylene foams with high densities and cell sizes in the microcellular range. The materials under study had a relative density between 0.27 and 0.92, a homogeneous and multi-structured cellular structure with a dense skin…
We investigate the relationship between the multiexponential photoluminescence (PL) dynamics of large nanocrystal (NC) ensembles and the intensity intermittency (blinking) characteristic of single NCs. A general model is developed and a simple fitting form derived for the analysis of PL decay curves allowing the extra…
