Phase Equilibria of CO2 Hydrate in the Aqueous Solutions of N-Butyl-N-methylpyrrolidinium Bromide

02.10.2015 | Xiao-Dong Shen; Zhen Long; Ling-li Shi; De-Qing Liang, Journal of Chemical & Engineering Data, 2015

This work aims at reporting the dissociation pressures of carbon dioxide simple hydrates in the aqueous solution of N-butyl-N-methylpyrrolidinium bromide at four different mass fractions (0.01, 0.05, 0.10, and 0.20) in the pressure range of (2.34 to 3.13) MPa and in the temperature range of ...


Saccharification of cellulosic biomass using sulfonated mesoporous carbon‐based catalysts

01.10.2015 | Eika W. Qian, Luh Putu Pitrayani Sukma, Sen Li, Aki Higashi, Environmental Progress, 2015

A series of sulfonated mesoporous carbon‐based catalysts with intact silica template (MC) were prepared through incomplete carbonization of sucrose followed by sulfonation. The MC catalysts were characterized by use of Fourier Transform‐infrared spectra, N2 adsorption–desorption, and titration ...


Gas-Phase Ozonolysis of Cycloalkenes: Formation of Highly Oxidized RO2 Radicals and Their Reactions with NO, NO2, SO2, and Other RO2 Radicals

01.10.2015 | Torsten Berndt; Stefanie Richters; Ralf Kaethner; Jens Voigtländer; Frank Stratmann; Mikko Sipilä; Markku Kulmala; H ..., Journal of Physical Chemistry A, 2015

The gas-phase reaction of ozone with C5–C8 cycloalkenes has been investigated in a free-jet flow system at atmospheric pressure and a temperature of 297 ± 1 K. Highly oxidized RO2 radicals bearing at least 5 O atoms in the molecule and their subsequent reaction products were detected in most ...


Amidinate-Stabilized Group 9 Metal–Silicon(I) Dimer and −Silylene Complexes

01.10.2015 | Sabrina Khoo; Hui-Xian Yeong; Yongxin Li; Rakesh Ganguly; Cheuk-Wai So, Inorganic Chemistry, 2015

The coordination chemistry of the amidinate-stabilized silicon(I) dimer toward group 9 metal complexes is described. The reaction of [LSi:]2 (1, L = PhC(NtBu)2) with [Ir(cod)Cl]2 (cod = 1,5-cyclooctadiene) in toluene at ambient temperature afforded the base-stabilized silicon(I) dimer-iridium ...


An alternative synthesis of the breast cancer drug fulvestrant (Faslodex[registered sign]): catalyst control over C-C bond formation

30.09.2015 | Diego Caprioglio; Stephen P. Fletcher, Chemical Communication, 2015

Fulvestrant (Faslodex®) was synthesized in four steps (35% overall yield) from 6-dehydronandrolone acetate. Catalyst controlled, room temperature, diastereoselective 1,6-addition of the zirconocene derived from commercially available 9-bromonon-1-ene was used in the key C–C bond forming step.


Sustainability, Vol. 7, Pages 13317-13333: Stabilization of Organic Matter by Biochar Application in Compost-amended Soils with Contrasting pH Values and Textures

29.09.2015 | Jien, Shih-Hao ; Wang, Chung-Chi ; Lee, Chia-Hsing ; Lee, Tsung-Yu, Sustainability, 2015

Food demand and soil sustainability have become urgent concerns because of the impacts of global climate change. In subtropical and tropical regions, practical management that stabilizes and prevents organic fertilizers from rapid decomposition in soils is necessary. This study conducted a ...


Behavior of Yersinia enterocolitica in UF White Cheese: Impact of Different Storage Temperatures on Various Strains

28.09.2015 | Elham AbdollahI, Shahram Hanifian, Journal of Food Safety, 2015

Abstract This study aimed to investigate the effect of different temperatures on survival of various strains of Yersinia enterocolitica during the storage of ultra‐filtered (UF) white cheese. UF pasteurized cow milk was inoculated with 3 log colony‐forming unit per gram of two standard ...


Energies, Vol. 8, Pages 10775-10795: ANN-Based Prediction and Optimization of Cooling System in Hotel Rooms

28.09.2015 | Moon, Jin Woo; Kim, Kyungjae ; Min, Hyunsuk, Energies, 2015

This study aimed at developing an artificial-neural-network (ANN)-based model that can calculate the required time for restoring the current indoor temperature during the setback period in accommodation buildings to the normal set-point temperature in the cooling season. By applying the ...


Effect of aluminum thickness and etching time of aluminum induced texturing process on soda lime glass substrates for thin solar cell applications

25.09.2015 | Mustafa Ünal, Hisham Nasser, Mete Günöven, İlkay Sökmen, Aydın Tankut, Raşit Turan, physica status solidi (c), 2015

Abstract In this study, aluminum induced texturing (AIT) technique is used to increase light absorption in thin film by way of increasing the portion of the diffuse transmitted light (haze). For this purpose, various AIT process parameters such as starting aluminum thicknesses, annealing ...


Low Temperature Carbothermal Reduction Synthesis of ZrC Nanofibers Via Cyclized Electrospun PVP/Zr(OPr)4 Hybrid

25.09.2015 | Raziyeh Ghelich, Rouhollah Mehdinavaz Aghdam, Fatemeh Sadat Torknik, Mohammad Reza Jahannama, International Journal of Applied Ceramic Technology, 2015

The fabrication capability of zirconium carbide (ZrC) nanofibers by a novel polymeric solution was examined using electrospinning method. The electrospinnable solution was prepared from the reaction of zirconium n‐propoxide (Zr(OPr)4) with acetylacetone and acetic acid followed by the addition ...
