Related to oxidation:oxidation number,oxidation state ox·i·da·tion (ŏk′sĭ-dā′shən) n. 1.The combination of a substance with oxygen. 2.A reaction in which the atoms of an element lose electrons and the valence of the element is correspondingly increased. ...
However, a great number of microcracks penetrating the whole inner oxide layer were observed (Fig. 9.6). The AE test showed that the oxide scale did not crack during the isothermal oxidation at 1100°C for 1 hour (Fig. 9.7) [49], but the scale cracked during the cooling stage. Cracks ...

A number of enantiopure N-sulfonyloxaziridines, most derived from camphor, have been used for this purpose as shown in Scheme 4. Of these reagents, the (−)-N-(phenylsulfonyl)(3,3-dichlorocamphoryl)oxaziridine 145 generally gives the highest ee’s. Representative examples of asymmetric ...
It has become increasingly more clear that, for a number of reasons, the titanium aluminides will be the first “new” metallic materials introduced into commercial high temperature applications (probably aircraft gas turbines and automobiles engines) in many years. As a result a very ...
In addition, the number of reports on unaccounted high nitrogen losses in wastewater treatment is gradually increasing, indicating that anaerobic ammonium oxidation may be more widespread than previously assumed. The recently developed nitrification systems in which oxidation of nitrite to nitrate is ...
Data-dependent acquisition of MS/MS spectra (AutoMSn) was performed using a 3 s duty cycle at 2 Hz acquisition rate for full MS spectra and a variable number of MS/MS experiments at precursor intensity scaled spectra rate (3 Hz MS/MS spectra rate @ 2000 counts, 20 Hz MS/MS ...
This invention significantly reduces the number of steps required to create N-well and P-well regions on a silicon substrate by eliminating the need for a nitride deposition step and a steam oxidation step, both of which are utilized by the conventional process. 展开 ...
Financial support from Swedish Foundation for Strategic Research (SSF, Stiftelsen för Strategisk Forskning) is acknowledged [Project reference number ID17-0078]. SCM is supported through the Sêr Cymru II programme funded through the Welsh European Funding Office (WEFO) under the European Regional ...
The reported procedure allows a decrease in number of species and reactions with only a minor loss of model accuracy. The simplified model is of very compact size and gives an advantageous starting point for further model reduction. By this chemically lumped general mechanism without further ...
