Publication date: August 2015 Source:New Carbon Materials, Volume 30, Issue 4 Author(s): Jian Wang, Meng Wang, Ji-ru Xiong, Chun-hua Lu Two kinds of graphene prepared by a high-temperature exfoliation and a solvothermal method were used as supports of a TiO2 catalyst (P25) from ...


Thermally Driven Large N‐Type Voltage Responses from Hybrids of Carbon Nanotubes and Poly(3,4‐ethylenedioxythiophene) with Tetrakis(dimethylamino)ethylene

02.10.2015 | Hong Wang, Jui‐Hung Hsu, Su‐In Yi, Suk Lae Kim, Kyungwho Choi, Gang Yang, Choongho Yu, Advanced Materials, 2015

Hybrids of carbon nanotubes (CNTs) and poly(3,4‐ethylenedioxythiophene) (PEDOT) treated by tetrakis(dimethylamino)ethylene (TDAE) have large n‐type voltages in response to temperature differences. The reduced carrier concentration by TDAE reduction and partially percolated CNT networks embedded ...


A Low Temperature Molten Salt Process for Aluminothermic reduction of Silicon Oxides to Crystalline Si for Li-ion Batteries

30.09.2015 | ning Lin; Ying Han; Jie Zhou; Kailong Zhang; Tianjun Xu; Yongchun Zhu; Yitai Qian, Energy & Environmental Science, 2015

A low tempertaure molten salt process is developed to prepare crystalline Si nanoparticles through the reduction of micro-sized high silicon zeolite by metallic Al (or Mg) in molten AlCl3. The reaction can be initiated at 200 oC, and the yield is about 40%. As the reaction temperqature increases ...


Extended Validation of Dynamic Irreversible Thermoporation: A Novel Thermal Process for Microbial Inactivation

28.09.2015 | Marco Cammalleri, Emiliano Pipitone, Teresa Rubino, Daniela Maria Geraci, Floriana Bonura, Caterina Mammina, Journal of Food Process Engineering, 2015

Abstract A novel thermal treatment for microorganism inactivation, characterized by a very rapid temperature increase (up to 30C/s) and a low final temperature (up to 65C) maintained for a relatively short holding time, has been recently presented and tested by the authors, showing microbial ...


Trap‐assisted photon‐enhanced thermionic emission from polycrystalline diamond films

28.09.2015 | S. Elfimchev, M. Chandran, R. Akhvlediani, A. Hoffman, physica status solidi (a), 2015

In this work, the photoelectron emission (PEE) in the temperature range of 298–873 K was investigated from undoped hydrogenated polycrystalline diamond (Poly‐Di) film. Poly‐Di film was deposited by hot filament chemical vapor deposition (HF CVD) method on silicon substrate. The sample was ...

Dual‐Templated Cobalt Oxide for Photochemical Water Oxidation

25.09.2015 | Xiaohui Deng, Hans‐Josef Bongard, Candace K. Chan, Harun Tüysüz, ChemSusChem, 2015

Abstract Mesoporous Co3O4 was prepared using a dual templating approach whereby mesopores inside SiO2 nanospheres, as well as the void spaces between the nanospheres, were used as templates. The effect of calcination temperature on the crystallinity, morphology, and textural parameters of the ...


Alkaline partial wet oxidation of lignin for production of carboxylic acids

22.09.2015 | Abayneh Getachew Demesa, Arto Laari, Ilkka Turunen, Mika Sillanpää, Chemical Engineering & Technology, 2015

Abstract Production of carboxylic acids by partial wet oxidation of alkali lignin was studied experimentally. The factors influencing the different types of products, their yields and concentrations were investigated. Formic, acetic, succinic, oxalic and glutaconic acids were the main ...


Energies, Vol. 8, Pages 10504-10521: Optimal Energy Reduction Schedules for Ice Storage Air-Conditioning Systems
