We report the photoluminescence characterization of Dy(3+)-activated NaM(4)(VO(4))(3) (M = Ca, Ba, Sr) phosphors prepared by a solid-state method. The synthesis was confirmed by X-ray diffraction (XRD) characterization and photoluminescence (PL) emission results showed sharp blue and yellow bands for NaM(4)(VO(4))(3)…
Heated styling appliances, such as straightening irons, have grown in popularity in recent years, as have hair products such as heat-protection sprays. In this study we investigate whether the water in a heat-protection spray can affect the level of damage caused by heat styling. Tryptophan damage from heat styling wa…
Abstract High‐rate deposition of electrochromic organotungsten oxide (WOxCy) films onto flexible PET (polyethylene terephthalate)/ITO (indium tin oxide) substrates by atmospheric pressure‐plasma enhanced chemical vapor deposition (AP‐PECVD) with atmospheric pressure plasma jet (APPJ) under various substrate distances…
We present a microscopic investigation of the temperature dependence of stripe domains in perpendicularly magnetized Ni films on Cu(001) using photoelectron emission microscopy in combination with x-ray magnetic circular dichroism (XMCD) in the resonant absorption of soft x rays. When the temperature approaches the Cu…
Abstract Ferromagnetic compound CeAgGa crystallizes in CeCu2 Imma structure with Ag and Ga atoms distributed randomly at 8h position. We report X‐ray photoemission (XPS) valence‐band spectra for CeAgGa and compare the results with those obtained from the full potential linear augmented plane‐wave (FP‐LAPW) method. In…
Preparatory experiments for the ITER-Like Wall in JET were carried out to simulate the massive Be first wall by a thin Be layer, induced by evaporation of about 2.0 g Be, and to study its impact on fuel retention and divertor radiation with reduced C content and N seeding. Residual gas analysis reveals a reduction of…
Abstract Amorphous SiC:H thin films were grown by hot wire chemical vapour deposition from a SiH4/CH4/H2 mixture at a substrate temperature below 400 °C. Thermal annealing in an argon environment up to 900 °C shows that the films crystallize as μc‐Si:H and SiC with a porous microstructure that favours an oxidation pro…
Abstract Modification of polymers by electron beam (EB) radiation is a potential method for the development of new polymers and composites. This investigation reports the modification of chlorinated polyethylene (CPE) using electron beam radiation. In this case, the modification was carried out by using different dose…
Sodium (Na+), calcium (Ca2+), and magnesium (Mg2+) in poor quality irrigation water participate in ion-exchange processes in soil, resulting in displacement and leaching of K+ from micaceous minerals into solution and in the potential for elevated concentrations in groundwater. Knowledge of the rate of decrease of K+…
This paper builds on a previously published development work involving a novel thermal field sensitivity model for underground cable systems, based on finite elements, which has been verified by experimental laboratory measurements. The paper reports on a new approach to underground cable thermal field optimisation us…
Abstract This research news is presented to help researchers with their development of CVD‐produced polymer thin films, but could also be utilized for thicker coatings and for liquid‐deposited thin films. This arises from the observation that many CVD researchers deposit polymer thin films, and then use them without a…
This paper presents an innovative application of the adaptive notch filters for flicker disturbance extraction and mitigation. This paper demonstrates a new cascaded scheme of adaptive notch filters and regular notch filters. This suggested scheme is used for tracking the frequencies of flicker disturbances and for th…
Research on the counterion binding equilibria of the linear polyelectrolytes with anionic groups, i.e., calboxyl, sulfate, or phosphate group, is important for understanding the effect of the electrostatic interaction on the functionalities of polyions. For the analysis of the counterion binding equilibria of polyelec…
We analyze the optical effects associated with an adiabatic rotation of a plane of polarization in a twisted nematic liquid crystal. The experimental verification was performed with a cell with linear rubbing of a front surface and circular rubbing of a rear surface. The expectations of the liquid crystal's orientatio…
The dynamics of an impurity (or tracer particle) immersed in a dilute granular gas under uniform shear flow is investigated. A non-equilibrium phase transition is identified from an exact solution of the inelastic Boltzmann equation for a granular binary mixture in the tracer limit, where the impurity carries either a…
In Pseudomonas putida, as in many other eubacteria, cyclopropane fatty acids (CFAs) accumulate in the membrane during the stationary phase of growth. Here, we show that cfaB gene expression in P. putida KT2440 is dependent on the RpoS sigma factor that recognizes the sequence 5'-CTACTCT-3' between -8 and -14. We have…
Abstract Among short fiber reinforced composites, those with rubbery matrices have gained great importance due to the advantages they have in processing and low cost, coupled with high strength. These composites combine the elastic behavior of rubbers with strength and stiffness of fibers. Aramid fibers have been chos…
The Corynebacterium glutamicum whcA gene is known to play a negative role in the expression of genes responding to oxidative stress. The encoded protein contains conserved cysteines, which likely coordinate the redox-sensitive Fe-S cluster. To identify proteins which may interact with WhcA, we employed a two-hybrid sy…
The rate constants of the reactions of HOI molecules with H, OH, O ((3)P), and I ((2)P(3/2)) atoms have been estimated over the temperature range 300-2500 K using four different levels of theory. Geometry optimizations and vibrational frequency calculations are performed using MP2 methods combined with two basis sets…
Flavins mediate a wide variety of chemical reactions in biology. To learn how one cofactor can be made to execute different reactions in different enzymes, we are developing solid-state NMR (SSNMR) to probe the flavin electronic structure, via the (15)N chemical shift tensor principal values (δ(ii)). We find that SSNM…
