A previous study, leading to the redefinition of Seminavis ventricosa (Gregory) Garcia-Baptista and some related taxa, made it clear that a considerable number of species exist within Seminavis D.G. Mann. Many species are still classified under Amphora Ehrenberg, although they clearly share common morphological featur…
Abstract We have developed a polymer dispersed cholesteric liquid crystal which exhibits two stable states at zero field: reflecting planar texture and non‐reflective focal conic texture. Both states have thresholds under driving voltage pulses. The material can be used to make multiplexed displays on passive matrix.…
Nedium cape-codii Siver & Hamilton sp. nov. is described from a small glacial kettle lake situated on the Cape Cod peninsula, Massachusetts, U.S.A. Nedium cape-codii is a large diatom with slightly bowed margins, a single longitudinal canal along each valve margin and sagittate apices. Each areola is covered externall…
The alignment mechanism of a polyimide surface bombarded with an atomic beam is investigated. Atomic beam treatment of polyimide films allows a liquid crystal (LC) to align parallel to the beam direction. This alignment mechanism is demonstrated by the selective destruction of double bonds in polyimide. The optical re…
Pulsed laser deposition has been used to grow highly oriented SrxBa1−xNb2O6 (SBN:x) on (001)MgO and miscut MgO (2° off 001 toward 100) in the presence of a pulsed O2 jet. The target stoichiometry was SBN:52±1.5%, but films grown at 700 °C were cation deficient and had a final composition of SBN:61±1.5%. Visually, the…
Depletion interactions between colloidal particles dispersed in a fluid medium are effective interactions induced by the presence of other types of colloid. They are not instantaneous but built up in time. We show by means of Brownian dynamics simulations that the static (mean-field) depletion force between two guest…
We describe a modular detector system suitable to intercept the diffracted x-ray radiation (Debye–Scherrer rings) in a transmission geometry setup at monochromatic tunable synchrotron radiation beamlines. The detector consists of several independent channels composed of a motorized front slit and a rear detector slit…
An elaborate finite element formulation was developed for the triaxial woven fabric (TWF) composites and this is presented in a parallel publication [Zhao, Q. and Hoa, S.V. Triaxial Woven Fabric (TWF) Composites With Open Holes (Part I): Finite Element Models For Analysis, Accepted, Journal of Composite Materials, thi…
An ethynylene-bridged zinc porphyrin dimer bearing metal-coordinating groups, such as bis[{5-(4-pyridyl)-15-(3,5-didodecyloxyphenyl)porphyrinato}zinc] Z2, self-assembles in CHCl 3 to form a rectangular-shaped supramolecular nano box, in which all the Z2 units preferentially adopt a planar conformation with a syn-paral…
In recent years, single crystal Cu-Al-Ni alloys with shape memory behavior (SMB) became generally commercialized. They achieved the level of extended application, including upper limb human prosthesis with anthropomorphic characteristics. An actuator based in single crystal Cu-Al-Ni alloy was tested as a prototype for…
Borocookeite, ideally Li 1+3x Al 4-x (BSi 3 )O 10 (OH,F) 8 (where “x” varies in the range 0.00-0.33 apfu), in which [4] Al is replaced by B relative to cookeite, occurs as a late-stage pocket mineral in the Sosedka and Mokhovaya pegmatite veins, Malkhan gem tourmaline deposit, Chikoy district, Chita oblast, Russia. Bo…
Abstract Among the derivatives of ( E )‐cinnamic acid for which the solid‐state photochemical properties have been studied, ( E )‐4‐formylcinnamic acid ( 1 ) has already received much attention. Given the inability to prepare single crystals of the β ‐polymorph of 1 that are of suitable size and quality for structural…
Because analytical expressions are required to run optimization software, this subject is very topical. This work uses equivalent permeability to homogenize the winding structure and approximations for the window field. A progressive approach leads to the needed expressions for a transformer built around a gapped ferr…
In this study, 2′,4-dichloro-5′-fluoro-1-ene-2-(4-hydroxyphenyl)phenone (EHP) was synthesized using 4-hydroxybenzaldehyde and 2, 4-dichloro-5-fluoro acetophenone (DFA); 4-[3-(2,4-dichloro-5-fluorophenyl)-3-oxoprop-1-en-1-yl]phenyl acrylate (EAP) was prepared by reacting EHP with acryloyl chloride. Poly(EAP) was prepar…
The phase stability of nanograined Fe–12Ni powders is studied by means of both experiment and theoretical calculations. By means of a magnetic field accompanied by an ultrasonic vibration dispersal, the nanograined Fe–12Ni powders synthesized by the gas condensation were successfully separated into a face-centred-cubi…
The photogeneration of nitric oxide (NO) using laser flash photolysis was investigated for S-nitroso-glutathione (GSNO) and S-nitroso-N-acetylcysteine (NacySNO) at pH 6.4 (PBS/HCl) and 7.4 (PBS). Irradiation of S-nitrosothiol with light (lambda = 355 nm followed by absorption spectroscopy) resulted in the homolytic de…
Abstract Oxide dispersion strengthened (ODS) ferritic materials obtained by mechanical alloying (MA) display particular microstructure and texture. In this paper a microstructural characterization of an INCOLOY MA 956 alloy in the recrystallized (zone annealed) condition is presented. The alloy exhibits a highly aniso…
Abstract Design architecture of realizing high performance IPS‐LCDs with a 30% improved transmittance, less color shifting, and faster response time of less than ms 16 in the grayscales was represented. The newly developed pixel structure, consisting of transparent electrodes arranged on organic insulator, improved th…
Abstract The number and weight chemical composition distributions in random terpolymers were derived using a statistical approach. The solution was then generalized to comprise higher multicomponent copolymers. The analytical solution was verified with Monte Carlo simulations and by considering limiting cases. Chemica…
To characterize the sorption behavior of a fibrous assembly, an experimental method must measure the sorption rate and the capacity in conditions similar to those found in the real state. The gravimetric absorbency testing system (GATS) has advantages in that it can dynamically observe the spontaneous transplanar upta…
