This paper describes the application of nanoparticle bombardment with time-of-flight secondary ion mass spectrometry (NP-ToF-SIMS) for the analysis of native biological surfaces for the case of sagittal sections of mammalian brain tissue. The use of high energy, single nanoparticle impacts (e.g. 520 keV Au400) permits desorption of intact lipid molecular ions, with enhanced molecular ion yield ...

Here we show that combustion sources, including waste incinerators, metallurgical processes, power-heating systems and so on, are also important emitters of polybrominated diphenyl ethers (PBDEs) to the atmosphere. Geometric mean PBDE concentrations in the stack flue gases of the combustion sources ranged from 8.07 to 469 ng/Nm3. The sinter plants (24.7 mg/h), electric arc furnaces (EAFs) (11.3...

BACKGROUND Gas exchange measurements for carbon dioxide elimination (V̇CO2 ) and oxygen consumption (V̇O2 ) have been used to derive resting energy expenditure and guide energy prescription. Volumetric capnography is used in intensive care units and provides V̇CO2 measurements that could be used for titrating respiratory and nutritional support. We have recently suggested that measuring V̇CO2 may b...

Heavy oil and biomass co-gasification has been analyzed through a model developed in Aspen Plus™ v 11.0 software. The was used to assess main gasification parameters, such as cold gas efficiency, yield, low heating value (LHV), producer composition, using air oxygen agents. Subsequently, energy use the Rankine cycle performed GateCycle™ v11.1.2.4.850 Likewise, economic indicators of integrated ...

India has large proven reserve of coal but most the quantity ash. Utilization this high ash content is again a verychallenging task. Presently, gasification coals not yet been in application due to difficulties arising from handlingprocesses. In work an attempt was made design partially fluidized bed reactor that can handle 30 kg/hr as feedstock. By usingan appropriate procedure complete hybrid...

The concentration of low-concentration coalbed methane extracted from underground coal mine fluctuates greatly, which does not meet the requirements intake coalbed-methane utilization devices. Due to this fluctuation, coalbed-methane-utilization device cannot maintain stable and safe operation. gas-mixing is mainly used in systems, providing each with a feed gas source qualified concentration. ...

The new ternary stannides RE2Au2Sn (RE = Gd, Tb) and indides R E2Au2In (RE = Y, G d-T m , Lu) were synthesized by arc-melting of the elemental components and subsequent annealing at 800 °C. While Gd2Au2Sn, Tb2Au2Sn and the indides with RE = Y, G d -E r crystallize in the ordered U3Si2 structure, Tm2Au2In and Lu2Au2In adopt the ordered Zr3Al2 structure, respectively. The crystal structure of Dy2...

Fe2B2O5, synthesized under mild high-pressure / high-temperature conditions of 3 GPa and 960 ◦C, possesses a structure isotypic to the triclinic pyroborates M2B2O5 withM = Mg, Mn, Co, and Cd. Although the parameter pressure is not essential to the synthesis of Fe2B2O5, the specific conditions enhance the crystallinity of the product. Therefore, the crystal structure of the iron pyroborate Fe2B2...

In combination of direct phase retrieval of coherent x-ray diffraction patterns with a novel tomographic reconstruction algorithm, we, for the first time, carried out quantitative 3D imaging of a heat-treated GaN particle with each voxel corresponding to 17 x 17 x 17 nm3. We observed the platelet structure of GaN and the formation of small islands on the surface of the platelets, and successful...

NOx removal from a smoke tube boiler flue gas was investigated using a commercial ozonizer for indirect NO oxidation and a Na2SO3 chemical scrubber. The flue gas flow rate was in the range of 410 Nm/h-1480 Nm/h, the gas temperature of 185 °C-325 °C, and NOx concentration of around 40 ppm in city gas firing. Operational and performance data were obtained. The NOx removal efficiency was clearly d...
