We report results from X-ray synchrotron residual strain investigations of conically shaped 17-4PH stainless steel samples treated to different shot-peen intensities. The residual strains are compared to the as-manufactured condition as well as a sample coldwater quenched. The magnitudes of the induced residual strain…
Deterministic diffusive systems, such as the periodic Lorentz gas, multibaker map, as well as spatially periodic systems of interacting particles, have nonequilibrium stationary states with fractal properties when put in contact with particle reservoirs at their boundaries. We study the macroscopic limits of these sys…
The crystal structure of Sr10Ga6O19 was investigated by in situ single-crystal X-ray diffraction in the temperature range 298-673 K. At ambient conditions the compound shows a (3 + 1)-dimensional modulated structure in the superspace group C2/c(0beta0)s0 [a = 34.9145 (13), b = 7.9369 (2), c = 15.9150 (7) A and beta =…
An order‐disorder type potassium ferrocyanide trihydrate (KFCT) is a coordination compound forming lemon‐ yellow monoclinic ferroelectric crystals with curie temperature 251 K. KFCT crystals have been grown by temperature lowering solution growth technique. Solubility of KFCT has been determined for various temperatur…
Pressure evolution of LaGaO3, CeGaO3, PrGaO3, NdGaO3, La0.75Pr0.25GaO3 and La0.63Nd0.37GaO3 crystal structures was studied using powder diffraction with synchrotron radiation at ambient temperature in a broad pressure range. Structural instabilities corresponding to phase transformations have been observed in all stud…
The bacterial tetracycline transcription regulation system mediated by the tetracycline repressor (TetR) is widely used to study gene expression in prokaryotes and eukaryotes. To study multiple genes in parallel, a triple mutant TetR(K(64)L(135)I(138)) has been engineered that is selectively induced by the synthetic t…
Conjugated polymers have received a lot of attention, since they combine the best features of metals or semiconductors with those of synthetic polymers. For instance, solar cells based on poly(2,7-carbazole) derivatives have revealed power-conversion efficiencies up to 6%. This class of materials could lead to printab…
Abstract Ethylamine adduct (30 Kg) was prepared in an industrial field by reaction of ethylamine with epoxydized soybean oil, oxiran content 6.5, and identified by infra‐red spectroscopy. The prepared adduct was emulsified using both polyoxyethylene sorbitan monooleate in the continuous medium and sorbitan monooleate…
Fully dense anatase and rutile (TiO2) films were coated on (0001) α-quartz wafers using ultrasonic spray pyrolysis in air at 400°C for 2 h. The TiO2 films were annealed subsequently in air for 4 h at 600, 800 and 1000°C respectively. The films were characterised using X-ray diffraction (mineralogy), ultraviolet visibl…
Abstract Two isostructural complexes [Ca(hssal)(H2O)2]n (1) and [Sr(hssal)(H2O)2]n (2) (hssal2– = 5‐sulfosalicylate anion) are obtained byusing the ligand 5‐sulfosalicylic acid and alkaline earth metal salts under hydrothermal conditions. Their structures were determined by single‐crystal X‐ray diffraction analysis an…
Breast cancer (BCa) is the most commonly occurring cancer in women, comprising almost one third of all malignancies. Previously we reported that the n-hexane fraction (hSL) of the Siddha herbal medicine, Semecarpus Lehyam, relatively sensitized estrogen receptor-negative (ER(-)) BCa when compared to estrogen receptor-…
Turkey feather fibers were converted into yarn and knitted fabrics for a study into the feasibility of their use as textile products. Yarns containing blends of nylon and up to 30% of turkey feather fibers were spun by combining novel techniques with commercial yarn spinning machinery. These yarns were tested for dete…
Abstract This study proposes the new concept of reducing the birefringence of poly(ethylene naphthalate) (PEN) by a novel alloy with fluorene‐based polyester (FBP) involving the “cardo” structure in it. The alloys composed of PEN and FBP were prepared by simple melt blending method (process A) and reactive melt blendi…

The behaviour of hydrogen in metals has attracted scientific attention for many decades and is interesting from both basic research and technological points of view. Metal hydrides find a wide range of applications of which the most prominent is the reversible hydrogen storage. This is of great importance in view of p…
Abstract The influence of the processing variables on the birefringence and polymer/gas interface distribution is analyzed for polystyrene moldings obtained by gas‐assisted injection molding (GAIM) under various processing conditions. The processing variables studied were: melt and mold temperatures, shot size, gas pr…
