ABSTRACT Functionalization of NR with a bromine atom was developed and explored for its application in a silica-reinforced NR system. Two possible pathways were investigated: the direct addition of a bromine atom using N-bromosuccinimide (NBS) with FeCl2 as a catalyst in the latex phase (NR–Br); and an indirect method…
Abstract We report the room-temperature and low-temperature transport properties of a poly(2,5-bis(3-hexadecylthiophene-2-yl)thieno[3,2-b]thiophene) (PBTTT) film gated with an ionic liquid based on 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide at different annealing temperatures of the PBTTT film. By…
Abstract The authors report the fabrication of p‐type ZnO thin films with improved thermal stability. The p‐type ZnO thin films were obtained by oxidizing Zn3N2:Al thin films in an oxygen ambient. Both Zn3N2:Al and Zn3N2 thin films were deposited on fused silica substrates at 100 °C by megnetron sputtering. X‐ray diff…
The biocompatibility of Nickel-Titanium (NiTi) archwires was investigated by simulating actual contact state of archwires around brackets, which enabled incorporation of realistic mechanical conditions into ex situ experiments. Specifically, archwires (undeformed, and bound to brackets on acrylic dental molds) were st…
The magnetization and specific heat of TmV 2 Al 20 single crystals were measured in the temperature range from 0.5 to 300 K in external magnetic fields up to 7 T. TmV 2 Al 20 was found to be paramagnetic above 0.5 K. Clear magnetic anisotropy was observed along the three principal crystallographic axes in the field ab…
A synopsis of Cyanogomphini Carle, 1986 (sensu Belle 1996), including all species currently under the genera Cyanogomphus Selys, 1873, and Tibiagomphus Belle, 1992, is provided. Cyanogomphus angelomachadoi sp. nov. (Holotype ♂ deposited in DZRJ: Brazil, Minas Gerais State, Jaboticatubas municipality, Parque Nacional d…
Electrochromic (EC) properties of tungsten-molybdenum oxide (W 1-y Mo y O 3 ) thin films were investigated. The films were deposited on indium tin oxide covered glass by reactive DC sputtering from tungsten and molybdenum targets. Elemental compositions of the W 1-y Mo y O 3 films were determined by Rutherford back sc…
The formation of core/shell structures in hydrogels upon interaction with surfactants is a well-known phenomenon, but whether they are equilibrium states or not is still under debate. This paper presents an equilibrium theory of phase coexistence in hydrogels meant to answer the question of the stability of core/shell…

Two trifunctional phenylethynyl-terminated imide oligomers, m-TPEPA and p-TPEPA, were systematically compared with the corresponding bifunctional phenylethynyl-terminated imide oligomer, BPEPA. The non-isothermal curing kinetics, Master Plots method, and rheological behaviour of the three high performance oligomers we…
The larva of Palaemnema brasiliensis Machado, 2009 is described and illustrated based on last-instar larvae and exuviae of reared larvae collected in a blackwater stream in Barcelos and Presidente Figueiredo municipalities, Amazonas state, Brazil. The larva of P. brasiliensis can be distinguished from the two South Am…
Abstract This work presents ASDEX Upgrade experiments, where the nitrogen deposition and re-erosion on divertor manipulator samples and the effect of its transport through the plasma were studied. These results are compared to WallDYN-DIVIMP simulations based on SOLPS plasma backgrounds and employing an improved WallD…
Abstract The alpha heating experiment in the Joint European Torus (JET) 1997 DTE1 campaign is re-examined. Several effects correlated with tritium content and thermal hydrogenic isotopic mass < A > weaken the conclusion that alpha heating was clearly observed. These effects delayed the occurrence of significant sawtoo…
The use of zinc oxide (ZnO) nanoparticles (NPs) for cancer is not yet clear for human clinical applications, which is primarily due to the lack of a better understanding of the action mechanisms and cellular consequences of the direct exposure of cells to these NPs. In this work, the authors have selected zinquin ethy…
The hydrolytic cleavage of pUC19 DNA as promoted by the trivalent cerium complex (CeL) of diaza-crown ether ligand L (1,4,10,13-tetraoxa-7,16-diazacyclooctadecane) was examined in detail. The interaction of CeL with calf thymus DNA was investigated by UV-Vis spectroscopy. Furthermore, studies on the effects of pH, rea…
The photodissociation dynamics of the methyl perthiyl (CH3SS) radical are investigated via molecular beam photofragment translational spectroscopy, using "soft" electron ionization to detect the radicals and their photofragments. With this new capability, we have shown that CH3SS can be generated from flash pyrolysis…
BACKGROUND: Atropine sulfate is an anticholinergic agent for treatment of hypertrophic pyloric stenosis and is orally administrated as a triturate with lactose hydrate. Because of the low safety margin of atropine sulfate, triturate uniformity is a key safety factor. In this study, we assessed the uniformity of atropi…
A well‐defined (BA)(AC)2 miktoarm star diblock copolymer, (PPEGMA32‐b‐PMMA41)‐b‐(PMMA45‐b‐PNIPAm19)2, is synthesized by the combination of ATRP and click reaction. The miktoarm star block copolymer and its precursors are characterized by means of NMR and SEC/MALLS measurements. The copolymer exhibits a low critical ag…
Thin films of tin sulfide (SnS) were prepared by thermal evaporation technique on glass substrates and on n-type Si substrate and their physical properties were studied. The phase of the obtained thin films before and after thermal treatment was confirmed by X-ray diffraction analysis and Raman spectra. Optical transm…
Summary In the presented work, influence of magnet shaping on cogging torque of surface‐mounted Permanent Magnet (PM) machines is investigated. The considered PM shape for the magnet shaping is the loaf‐shape PM with off‐set arcs. For the first time, based on the solution of the Poissons's equation, an analytical mode…
