Is Elevated Pressure Required to Achieve a High Fixed-Carbon Yield of Charcoal from Biomass? Part 2: The Importance of Particle Size
04-04-2013 | Liang Wang; Øyvind Skreiberg; Morten Gronli; Gregory Patrick Specht; Michael Jerry Antal, Jr., Energy & Fuels, 2013
The prosperity of Silicon Valley is built upon a foundation of wood charcoal that is the preferred reductant for the manufacture of pure silicon from quartz. Because ordinary pyrolysis processes offer low yields of charcoal from wood, the production of silicon makes heavy demands on the ...
(Naxk1−x)2Ta4O11(x≈0.93) piezoelectric phase from the transformation of Ta2O5 thin films of monoclinic structure
18-03-2013 | Journal of Solid State Chemistry, 2013
April 2013 Publication year: 2013Source:Journal of Solid State Chemistry, Volume 200 A phase of trigonal structure has been reported in previous articles to be piezoelectric with a very high longitudinal d 33 coefficient of several thousand pm/V (J. Solid State Chem. 184 (2011) ...
ChemInform Abstract: Structure Refinements of Members in the Brownmillerite Solid Solution Series Ca2Alx (Fe0.5Mn0.5)2‐xO5+δ with 1/2 ≤ x ≤ 4/3.
01-03-2013 | Stefan Stoeber, Guenther Redhammer, Susan Schorr, Oleksandr Prokhnenko, Herbert Poellmann, ChemInform, 2013
Abstract The title brownmillerite solid solutions are synthesized by a ceramic method starting with mixtures of CaCO3, Al2O3, Fe2O3, and MnO2 (Pt crucibles, 1250 °C, 8 d).
ChemInform Abstract: The New Barium Mercuride BaHg6 and Ternary Indium and Gallium Derivatives.
01-03-2013 | Marco Wendorff, Caroline Roehr, ChemInform, 2013
Abstract BaHg6 (I), BaIn1.2Hg4.8 (II), and BaGa0.8Hg5.2 (III) are obtained from melts of the elements in Ta crucibles by slow cooling from 500 to 200 °C.
X‐ray fluorescence analysis of Co, Ni, Pd, Ag, and Au in the scrapped printed‐circuit‐board ash
18-02-2013 | Yuya Hirokawa, Yasuhiro Shibata, Takayuki Konya, Yuya Koike, Toshihiro Nakamura, X-Ray Spectrometry, 2013
A method for the quantitative analysis of Co, Ni, Pd, Ag, and Au in the scrapped printed‐circuit‐board ash by X‐ray fluorescence (XRF) spectrometry using loose powder was developed. The printed‐circuit‐board samples were converted to ash pyrolytically in porcelain crucibles by sequential ...
ChemInform Abstract: Structure and Physical Properties of Single Crystal PrCr2Al20 and CeM2Al20 (M: V, Cr): A Comparison of Compounds Adopting the CeCr2Al20 Structure Type.
13-02-2013 | Michael J. Kangas, Devin C. Schmitt, Akito Sakai, Satoru Nakatsuji, Julia Y. Chan, ChemInform, 2013
Abstract Crystals of LnTi2Al20 (Ln: La—Pr, Sm, Yb), LnV2Al20 (Ln: La—Pr, Sm), and LnCr2Al20 (Ln: La—Pr, Sm, Yb) are prepared from the elements by the flux growth method (alumina crucibles, 1423 K, slow cooling to 1023 K).
ChemInform Abstract: The New Barium Zinc Mercurides Ba3ZnHg10 and BaZn0.6Hg3.4 — Synthesis, Crystal and Electronic Structure.
13-02-2013 | Michael Schwarz, Marco Wendorff, Caroline Roehr, ChemInform, 2013

Enhanced polarization switching in ferroelectric Bi0.5Na0.5TiO3 single crystals by defect control
16-01-2013 | Ken Yanai, Yuuki Kitanaka, Yuji Noguchi, Masaru Miyayama, Chikako Moriyoshi, Yoshihiro Kuroiwa, Kousuke Kurushima, S ..., physica status solidi (a), 2013
Abstract Single crystals of ferroelectric (Bi,Na)TiO3 (BNT) were grown by the top‐seeded solution growth (TSSG) method at a high oxygen pressure of 0.9 MPa using Pt crucibles and their conductivity (leakage current) and polarization properties were investigated at 25 °C along 〈100〉cubic. ...
Specific features of sublimation growth of bulk AlN crystals on SiC wafers
15-01-2013 | E. Mokhov, I. Izmaylova, O. Kazarova, A. Wolfson, S. Nagalyuk, D. Litvin, A. Vasiliev, H. Helava, Yu. Makarov, physica status solidi (c), 2013
Abstract The features of 2” AlN bulk crystal growth by the sublimation sandwich method (SSM) on SiC seeds in a graphite‐heated reactor are investigated. AlN growth conditions and crystal properties are compared with the results of SiC sublimation growth in the same reactor. The specifics ...
