Mesoporous In2O3 nanocrystals: synthesis, characterization and NOx gas sensor at room temperature

25.11.2015 | Jun Gao; Hongyuan Wu; Jiao Zhou; Liyuan Yao; Guo Zhang; Shuang Xu; Yu Xie; Li Li; Keying Shi, New Journal of Chemistry, 2015

Mesoporous In2O3 nanocrystals (INS) were successfully prepared using SBA-16 as the template. The INS-3 synthesized by the 0.3 M In(NO3)3 solution had 7.27 nm mean pore size and 82.32 m2•g-1 specific surface area, the mesoporous In2O3 nanocrystals were interconnected In2O3 small-grain (~ 5 nm) ...


Optical Studies of Poly(hydroxy imide) to Polybenzoxazole Thermal Rearrangement

20.11.2015 | Boz·ena Jarząbek, Magdalena Wójtowicz, Aleksandra Wolińska‐Grabczyk, Macromolecular Chemistry and Physics, 2015

Studies of the optical properties of poly(hydroxy imide) (HPI) exposed to stepwise heating from room temperature up to 400 °C are reported in this work. It is demonstrated that this new method can be used to monitor thermal rearrangement (TR) of HPI to polybenzoxazole (PBO). Temperature ...


Very High-Pressure Fuel-Slurry Integrated Gasifier/Gas Turbine (FSIG/GT) Power Generation Applied to Biomass

20.11.2015 | Marcio L. de Souza-Santos, Energy & Fuels, 2015

The work contributes to the study of the fuel-slurry integrated gasifier/gas turbine (FSIG/GT) concept for the electric power generation process consuming biomass or, more specifically, sugar cane bagasse (SCB). The FSIG/GT process allows for pumping of the solid fuel as a slurry into pressurized ...


Competing insertion and external binding motifs in hydrated neurotransmitters: IR spectra of protonated phenylethylamine monohydrate

19.11.2015 | Aude Bouchet, Markus Schütz, Otto Dopfer, ChemPhysChem, 2015

Hydration has a drastic impact on the structure and function of flexible biomolecules such as aromatic ethylamino neurotransmitters. The structure of monohydrated protonated phenylethylamine (H+PEA‐H2O) is investigated by infrared photodissociation (IRPD) spectroscopy of cold cluster ions using ...


Fast Photoresponse from 1T Tin Diselenide Atomic Layers

19.11.2015 | Peng Yu, Xuechao Yu, Wanglin Lu, Hsin Lin, Linfeng Sun, Kezhao Du, Fucai Liu, Wei Fu, Qingsheng Zeng, Zexiang Shen, ..., Advanced Functional Materials, 2015

Atomically layered 2D crystals such as transitional metal dichalcogenides (TMDs) provide an enchanting landscape for optoelectronic applications due to their unique atomic structures. They have been most intensively studied with 2H phase for easy fabrication and manipulation. 1T phase material ...


Simulation of biomass char gasification in a downdraft reactor for syngas production

19.11.2015 | Augustina Ephraim, Victor Pozzobon, Olivier Louisnard, Doan Pham Minh, Ange Nzihou, Patrick Sharrock, AIChE Journal, 2015

Abstract A steady‐state, one‐dimensional computational fluid dynamics model of wood char gasification in a downdraft reactor is presented. The model is not only based on reaction kinetics and fluid flow in the porous char bed but also on equations of heat and mass conservation. An original ...


Formation of 4(5)‐Methylimidazole in Aqueous d‐Glucose‐Amino Acids Model System

18.11.2015 | Faris Karim, J. Scott Smith, Journal of Food Science, 2015

Abstract The International Agency for Research on Cancer (IRAC) has classified 4(5)‐methylimidazole (4‐MeI) as a group 2B possible human carcinogen. Thus, how 4‐MeI forms in a d‐glucose (Glu) amino acids (AA) model system is important, as it is how browning is affected. An aqueous solution of ...


Enhanced O2 Flux of CaTi0.85Fe0.15O3−δ Based Membranes by Mn Doping

18.11.2015 | Jonathan M. Polfus, Wen Xing, Marit Riktor, Martin F. Sunding, Paul Inge Dahl, Sidsel M. Hanetho, Tommy Mokkelbost, ..., Journal of the American Ceramic Society, 2015

Dense symmetric membranes of CaTi0.85−xFe0.15MnxO3−δ (x = 0.1, 0.15, 0.25, 0.4) are investigated in order to determine the optimal Mn dopant content with respect to highest O2 flux. O2 permeation measurements are performed as function of temperature between 700°C–1000°C and as function of the ...


Synthesis of Hexagonal Boron Nitride Monolayer: Control of Nucleation and Crystal Morphology

18.11.2015 | Yijing Stehle; Harry M. Meyer, III; Raymond R. Unocic; Michelle Kidder; Georgios Polizos; Panos G. Datskos; Roderick ..., Chemistry of Materials, 2015

Monolayer hexagonal boron nitride (hBN) attracts significant attention due to the potential to be used as a complementary two-dimensional dielectric in fabrication of functional 2D heterostructures. Here we investigate the growth stages of the hBN single crystals and show that hBN crystals change ...


Mutual Solubility of Water and Hydrocarbons

18.11.2015 | Carl Landra; Marco A. Satyro, Journal of Chemical & Engineering Data, 2015

The accurate modeling of systems containing water and hydrocarbons is important to support key decisions related to the design, simulation, and optimization of a variety of industrial processes, ranging from refineries, to gas plants and liquified natural gas processing facilities. Processes of ...
