Photoionization-efficiency curves for C2H2 and C2D2 have been remeasured in the wavelength region from onset of ionization to 600 Å, using a gold-coated grating Hopfield continuum as photon source. The curve shapes molecule ions near threshold are compared with calculations Franck—Condon factors. Nearly exact agreement between experiment calculation is obtained when taking into account hot bands. A general discussion given shape molecule-ion that fragment ions, C2H+ C2D+. observed onsets...
Abstract Alginate is a naturally occurring polysaccharide commonly derived from brown algae cell walls which possesses unique features that make it extremely promising for several biomedical and pharmaceutical purposes. biomaterials are indeed nowadays gaining increasing interest in drug delivery tissue engineering applications owing to their intrinsic biocompatibility, non‐toxicity, versatility, low cost, ease of functionalization. Specifically, alginate‐based nanostructures show enhanced...
Using monochromatised synchrotron radiation as an excitation source, threshold photoelectron-photoion coincidence experiments have been performed on energy-selected states of O2+. Predissociation is observed for the b4 Sigma g- and c4 u- states. Two dissociation continua are between 23 24.5 eV.
The absolute electron impact ionization cross sections for lithium in the energy range between 100 and 2000 eV were measured by nonmodulated crossed beam technique. neutral is produced a Knudsen cell at right angles with beam. ions formed are collected on plate their intensity determined dc amplifier. condensed cold trap cooled liquid nitrogen, this temperature being much lower than that required to obtain total condensation. amount of metal deposited isotopic dilution technique atomic...
Photoionization-efficiency curves for ions of the molecule and selected fragments C2H4 CHDCHD are reported wavelength region from onset ionization to 600 Å. The minimum threshold is 10.50 eV both molecules. In addition, certain features ion-yield discussed identified as resulting vibrationally excited states or autoionization Rydberg levels leading electronically states. Threshold measurements acetylene permit calculation heats dissociation indicate that C2H2+ ion formed without excess...
The recyclability of polylactide acid (PLA) and poly (3-hydroxybutyrate-co-3-hydroxyvalerate (PHBV)-based biocomposites (10%, 20% 30% by weight sisal natural fibre) was evaluated in this work. mechanical thermal properties were initially determined shown to be similar commodity plastics, such as polyethylene or polypropylene. Three recycle steps carried out the recycled samples compared reference samples. tensile modulus increased for PLA biocomposites, whereas it hardly influenced recycling...
Addition of tricalcium phosphate (alpha-TCP) powders as an aqueous dispersion to a polymethylmethacrylate (PMMA) bone cement is shown produce class composites that due their microstructure and mechanical properties may be suitable for application substitutes. The PMMA forms solid cellular matrix with open cells about 100 micrometer in size incorporating TCP clusters. aggregates inside the form porous network, average mesopore diameters 0.1 micrometer, accessible from outer surface. If added...
MgO produced by vacuum decomposition of Mg(OH) 2 is formed as aggregates containing both open and closed pores. The surface area the volume pores, measured N adsorption, were found to be 300 m /g 0.14 cm 3 /g, respectively. Through calorimetric TEM studies, reported elsewhere, initial pores are shown 550 ± 150 0.19 samples sintered in presence water at 823 K. elimination coarsening dominate early stage sintering under conditions studied. From above observations, it argued that behavior...

Pellets from residues rice harvest (i.e., straw and husk) were produced their main properties evaluated. Firstly, pellets at lab scale varying operational conditions load compression wt % of feeding moisture content) to evaluate suitability for palletization. Successively, husk commercially produced. All the samples characterized in terms physical, chemical, physico-chemical properties. In addition, axial/diametral durability tests performed assess mechanical performance. analyzed compared...
Abstract La 1–x Sr x Co 1–y Fe y O 3– δ (LSCF) fibers are synthesized through the single‐needle electrospinning method. The formation of nanofibers is a function operating parameters, i.e., rotational speed support, solution feeding rate, and voltage, which investigated experimentally in this work. results show that 750 rpm, rate 0.5 mL h −1 , an voltage 17 kV allow to obtain tissues with average fiber diameter 0.590 μm porosity around 50%. subsequent calcination processes thermogravimetric...
