Municipal solid waste composting is seen as a promising technology in Sub-Saharan Africa to offset greenhouse gas emissions under the Clean Development Mechanism (CDM) program. The main reasons given therefore are the large organic fraction in municipal solid waste in this world region and the l...

The Cryogenic Dark Matter Search (CDMS II) experiment aims to detect dark matter particles that elastically scatter from nuclei in semiconductor detectors. The resulting nuclear-recoil energy depositions are detected by ionization and phonon sensors. Neutrons produce a similar spectrum of low-en...

The Clean Development Mechanism (CDM) under the Kyoto Protocol has two main objectives: Reducing emissions of greenhouse gases (GHGs) and contributing to sustainable development (SD) in developing countries. The empirical evidence indicates that the first goal has been fulfilled; however, the li...

As for the academics and policymakers, more attention has been given to the issue on how to drive green development of the manufacturing through regulations and innovations. We construct the extended Crépon-Duguet-Mairesse (CDM) model and employ the panel data of Chinese manufacturing industrie...

In most populated countries like India, the need for public and private transportation is much more essential as it one of the crucial sectors that helps in the economic growth. On the other hand, it is responsible for emitting greenhouse gases and causes serious air and noise pollutions. This i...

Adolescence is characterized by high significance of social interactions, along with a propensity to exhibit social facilitating effects of ethanol while being less sensitive than adults to the inhibition of social behavior that emerges at higher doses of ethanol. Among the neural characteristic...

A method has been developed that allows for the detection of the eleven stereoisomers of diphenylcyclobutanedicarboxylic acid in illicit cocaine samples, including χ-, γ-, and ε-truxillic acids and β- and δ-truxinic acids. These, and other carboxylic acids, were also detected as ester moiet...

Seven out of the eleven possible intact isomeric truxillines present in illicit cocaine have been isolated and identified. These truxilline alkaloids included α-, β-, γ-, δ-, ε-, ω- and neo-isomers. The individual truxillines were characterized via high-performance liquid chromatography—d...

The isomeric truxillines and their hydrolysis products are present as manufacturing impurities in most illicit, refined cocaine samples. Methodology is described for the comparative gas chromatographic determination of total isomeric truxilline manufacturing impurities/by-products, i.e., intact ...

The isomeric truxillines are a group of minor alkaloids present in all illicit cocaine samples. The relative amount of truxillines in cocaine is indicative of the variety of coca used for cocaine processing, and thus, is useful in source determination. Previously, the determination of isomeric t...

Four kinds of ZrVFe alloys with the C14 Laves phase structure had high hydrogen storage capacity under mild pressures, and those alloys would be promising for widespread application such as recovery of hydrogen derived from water splitting. Addition of titanium to ZrVFe lowered hydrogen desorpti...

Microstructural changes, thermodynamic and cyclic properties, total material cost and the cumulative energy demand of V(40−40·x)Fe(8−8·x)Ti26Cr26(FeV)(48·x) with 0 ≤ x ≤ 0.9 using commercial ferrovanadium (FeV) are investigated. The substitution of V + Fe by FeV (x = 0.9) raises the equilib...

Based on the analysis of XRD, SEM, P-C-isotherm measurements and absorption kinetics simulation, it was indicated that Ce addition was an effective way to inhibit the formation of C14 Laves phase, improve flatness of the plateau, increase hydrogen diffusion rate and enlarge hydrogen storage capa...

Hydrogen storage nanocomposites prepared by high energy reactive ball milling of magnesium and vanadium alloys in hydrogen (HRBM) are characterised by exceptionally fast hydrogenation rates and a significantly decreased hydride decomposition temperature. Replacement of vanadium in these material...

In the present study, the effect of boron and zirconium on the microstructural characteristics, ductility and the tensile strength of the wrought nickel-based superalloy 718Plus were investigated. In this regard, five alloys with different amounts of boron 0.00–0.016 wt%) and zirconium 0.0–0.1...

ObjectiveThe aim of this study was to assess artifacts generated by zirconium, titanium, and titanium–zirconium alloy implants on magnetic resonance imaging(MRI), computed tomography(CT), and cone beam computed tomography(CBCT) and to correlate the findings to the dose–area product and exposur...

The photon interaction properties of two zirconium alloys (zircaloy-2 and excel zirconium alloy) have been studied in this work by using WinXCom program in the energy range 1 keV to 100 MeV. The mass attenuation coefficient, partial interaction, effective atomic number and electron density were ...

The corrosion behavior of zirconium alloy was investigated using synchrotron scanning transmission X-ray microscopy and X-ray absorption spectroscopy. Scanning transmission X-ray micrographs showed different electronic structures at the oxide/metal interface of Zr–Nb–Sn alloy after exposure to...

BackgroundThe chemical characterization of metallic alloys and oxides is conventionally carried out by wet chemical analytical methods and/or instrumental methods. Instrumental neutron activation analysis (INAA) is capable of analyzing samples nondestructively. As a part of a chemical quality co...

A series of H-ZSM-5 zeolites with a silicon to aluminum ratio of 50–4000 but similar crystal size were synthesized and characterized by XRD, N2 sorption, NH3-TPD and Py-FTIR; the intrinsic effect of silicon to aluminum ratio on the selectivity to propene in the conversion of methanol to propene...
