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…
Abstract The aim of this work is to investigate the electrochemical behaviour of an archaeological bronze in several aqueous electrolytes (Na 2 SO 4 , NaCl, KOH, NaHCO 3 and Na 3 PO 4 ) at 0.01 M. The anodic polarization revealed the dissolution of the material independently from the corrosive medium, but the damaging…
The H 1 technology needle-punching process is a patented invention from Fehrer, AG. H 1 technology machinery is used to develop a set of polyester/cotton blended nonwoven substrates. A suitable protocol is developed to clean, process, and blend cotton with polyester fibers suitable for needle-punching on the needle-lo…
Abstract (DMET)2MBr4 (M = Fe, Ga) are isostructural organic conductors whose crystal structure consists of an alternate stacking of quasi one-dimensional chain-based donor layers and anion square lattices. The resistivity, ESR, magnetic susceptibility, magnetization, and magnetoresistance of these salts were investiga…
Abstract A novel and powerful method of microstructure control in polyolefins is presented. By dispersing tiny amounts of sorbitol derivatives in the polymer, the subsequent crystal growth can be controlled with modest prior flow‐fields; in particular high levels of preferred orientation are generated in the resultant…
A normal-mode anisotropic liquid-crystal (LC) gel is demonstrated. In the absence of an electric field, the light polarized along the rubbing direction is scattered. In the voltage-on state, the gel is highly transparent and is independent of polarization. Such a normal mode LC gel exhibits a modest contrast ratio, re…
Abstract With the aim of preparing new dyes for Q‐switching and/or mode‐locking Nd‐based lasers, such as Nd:YLF and Nd:YAG (emission wavelengths 1053 and 1064 nm, respectively), the syntheses of about 30 new neutral dithiolenemetal complexes belonging to the class [M(R,R′timdt) 2 ] have been carried out [M = Ni ( 4a −…
The morphology and taxonomy of species of the genera Cocconeis Ehrenberg and Psammococconeis Garcia from the Gulf of San Matías (Patagonia, Argentina) is documented in the present study. A total of 16 taxa of Cocconeis and one species of Psammococconeis were found in surface net hauls taken in shallow coastal waters o…
For a systematic study of the effect of laundering on plain woven cotton fabrics, specimens of poplin and sheeting fabrics (with and without a DMDHEU wrinkle resistant finish) are laundered under regimes designed to evaluate the effect of five common home laundering variables: use of detergent, rinse cycle softener, o…
