Widening Synthesis Bottlenecks: Realization of Ultrafast and Continuous‐Flow Synthesis of High‐Silica Zeolite SSZ‐13 for NOx Removal

20.03.2015 | Zhendong Liu, Toru Wakihara, Kazunori Oshima, Daisuke Nishioka, Yuusuke Hotta, Shanmugam P. Elangovan, Yutaka Yanaba ..., Angewandte Chemie International Edition, 2015

Abstract Characteristics of zeolite formation, such as being kinetically slow and thermodynamically metastable, are the main bottlenecks that obstruct a fast zeolite synthesis. We present an ultrafast route, the first of its kind, to synthesize high‐silica zeolite SSZ‐13 in 10 min, instead of ...

The ablative behavior of high linear chains and its role in thermal stability of polyethylene: A combined P‐TREF‐TGA study

19.03.2015 | Abbas Kebritchi, Mehdi Nekoomansh, Fereidoon Mohammadi, Hossein Ali Khonakdar, Polymer International, 2015

Abstract Ethylene copolymers contain short chain branches which have great influence on their properties. Distinguished ethylene/1‐hexene copolymer in terms of number of butyl short chain branches was precisely separated based on differences in crystallizability using P‐TREF method and then ...

Photon-Impenetrable, Electron-Permeable: The Carbon Nanotube Forest as a Medium for Multiphoton Thermal-Photoemission

19.03.2015 | Mehran Vahdani Moghaddam; Parham Yaghoobi; George A. Sawatzky; Alireza Nojeh, ACS Nano, 2015

Combining the photoelectric and thermionic mechanisms to generate free electrons has been of great interest since the early days of quantum physics as exemplified by the Fowler–DuBridge theory, and recently proposed for highly efficient solar conversion. We present experimental evidence of this ...

Long term annealing of C‐type kudzu starch: Effect on crystalline type and other physicochemical properties

18.03.2015 | Bao Zhang, Chunsen Wu, Hongyan Li, Xiuting Hu, Zhengyu Jin, Yaoqi Tian, Xueming Xu, Starch - Stärke, 2015

Kudzu starch samples were prepared by annealing (ANN) treatment in 1:1.5 starch to water ratio at 50°C for 1, 3, and 9 days. The effects of ANN on the morphology, structure, swelling power, solubility, and pasting properties of the resultant samples were evaluated. Scanning electron microscopy ...

Materials, Vol. 8, Pages 1074-1088: Cellular Response to Doping of High Porosity Foamed Alumina with Ca, P, Mg, and Si

13.03.2015 | Soh, Edwin ; Kolos, Elizabeth ; Ruys, Andrew J., Materials, 2015

Foamed alumina was previously synthesised by direct foaming of sulphate salt blends varying ammonium mole fraction (AMF), foaming heating rate and sintering temperature. The optimal product was produced with 0.33AMF, foaming at 100 °C/h and sintering at 1600 °C. This product attained high ...
