Isotopically light carbon dioxide in nitrogen rich gases: the gas distribution pattern in the French Massif Central, the Eifel and the western Eger Rift
Eger Rift French Massif Central Eifel carbon dioxide gas fractionation isotope composition
2015/9/10
Based on characteristics of the distribution pattern of the western Eger Rift spring gases, a distribution pattern is
presented for the gases of the French Massif Central. The central parts of these ...
Sources and fate of nitrate in a groundwater-fed estuary elucidated using stable isotope ratios of nitrogen and oxygen
nitrate oxygen isotope

We used d15N-nitrate (NO{
3 ) and d18O-NO{
3 to unravel the provenance and fate of NO{
3 in a groundwater-fed
estuary. A total of 13 monthly and two time series surveys were undertaken in the Werr...

A. Semiconductors B. Impurities in semiconductors C. Optical properties D. Hall effect measurement
2011/12/13
The nitrogen-doped, p-type ZnO film was grown by plasma-assisted molecular beam epitaxy (P-MBE) on c-plane sapphire (c-Al2O3) using radical NO as oxygen and nitrogen sources. The activation energy of ...
铁、氮共掺杂二氧化钛粉末的制备及光催化活性（Preparation and Photocatalytic Activity of TiO2 Powder Codoped with Iron and Nitrogen）
二氧化钛 铁 氮共掺杂 亚甲基蓝 光催化
2010/8/18
Using TiCl4 as the titanium source, nanoparticles of TiO2 doped with nitrogen(N-TiO2) were synthesized by triethylamine. TiO2 powder codoped with iron and nitrogen(Fe/N-TiO2) were prepared by adsorpti...
