Self-Catalytic Growth of Tin Oxide Nanowires by Chemical Vapor Deposition Process
We report on the synthesis of tin oxide (SnO 2 ) nanowires by a chemical vapor deposition (CVD) process. Commercially bought SnO nanopowders were vaporized at 1050 ∘ C for 30 minutes with argon gas continuously passing through the system. The assynthesized products were characterized using UV-visible absorption spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and high-resolution transmission electron microscopy (HRTEM). The band gap of the nanowires determined from UV-visible absorption was around 3.7 eV. The SEM micrographs revealed "wool-like" structure which contains nanoribbons and nanowires with liquid droplets at the tips. Nanowires typically have diameter in the range of 50-200 nm and length 10-100 m. These nanowires followed the vapor-liquid-solid (VLS) growth mechanism

Effects of helium ion irradiation on tungsten-based composites : neutron diffraction; as a real-time diffractometer
The weight ratio 6% was formed for this paper by B4C-2% (99.5% purity, 20 µm particle size),
TiC-1% (99.5% purity, 15 µm particle size), C (99.5% purity, 21 µm particle size) and the remaining part
is tungsten W (99.5% purity, 17 µm particle size) structure had been established. In order to get
homogeneous sinter, it was subjected to a temperature gradient of up to 1750 °C for 2 hours with a
temperature step of 5 °C per minute. In the study, neutron diffraction (ND) was performed using the timeof-flight technique (TOF) in the IBR-2M research reactor. The obtained data were refined with the
FULLPROF Rietveld suite. The results convey that it is different from the results obtained by X-Ray
diffraction.http://jomardpublishing.com/journals.aspx?lang=en&id=13Physic
Growth performance of South African Windsnyer pigs to the dietary inclusion of Amarula oil cake
Dietary inclusion of Amarula oil cake (AOC) in pig diets can ease pressure of relying on non-native feed sources and beneft
the swine industry. The study was conducted to determine the growth performance of Windsnyer pigs fed increasing levels of
AOC. Twenty-fve clinically growing male boars with an initial body weight of 19.92±8.74 kg were used in the study that
lasted 6 weeks. All pigs were allocated to diets in a completely randomised design. Five experimental diets were formulated
to contain 0, 50, 100, 150 and 200 g/kg DM of AOC. Average daily feed intake (ADFI), average daily gain (ADG), feed
conversion ratio (FCR), scaled average daily feed intake (SADFI), scaled average daily gain (SADG) and body weight (BW)
were calculated weekly. The diet afected ADFI, ADG, FCR and SADG (P<0.05). Scaled average daily feed intake was not
afected by the diet (P>0.05). There was a signifcant interaction between AOC inclusion and weeks of feeding on ADFI,
ADG and FCR (P<0.05). Age of pigs decreased FCR quadratically (P<0.001). A quadratic relationship between ADFI and
increasing levels of AOC was observed (P<0.05). Average daily gain, FCR and SADG decreased linearly with increasing
AOC levels (P<0.05). Using the broken stick analyses, the maximum inclusion of AOC was 102.17 g/kg DM. Amarula oil
cake can be incorporated in diets of Windsnyer pigs up to 100 g/kg DM without constraining growth performance.info:eu-repo/semantics/publishedVersio
