In simple terms a valve is a controller on the flow of a medium. Even though it’s a pipe fitting, valves are always considered in a special category owing to the involved precision. Read More SPECIAL FITTINGS In general materials categorised as special fittings don’t fall in our regular...
With the scaling of lateral dimensions in advanced transistors, an increased gate capacitance is desirable both to retain the control of the gate electrode over the channel and to reduce the operating voltage1. This led to a fundamental change in the gate stack in 2008, the incorporation of hig...
Compositions of the W and FeW phases were independent of x , while the Al content of the Fe-Al-W phase grew with increasing x . An alloy most closely fitting specification requirements was synthesized from green mixtures with a slightly lower amount of Al as compared to a stoichiometric one...
Finally, the kinetic has been also studied and universal equations have been successfully tested. ln(1 x) = k * t gives the best fitting result (where n = 0.4 and 0.6 are calculated for Fe and Cr, respectively). These values indicate that the leaching reaction follows the mixed kinetic ...
Full pattern fitting of the XRD profile pattern confirmed the structural transition from rhombohedral to pseudo-cubic phase. The magnetisation in BFO rises appreciably and found to be 0.463 emu/g for Bi 1-x Ba x Fe 1-y Co y O 3 (x=0.2, y=0.05) ceramic nanoparticles. The abrupt ...
Fitting parameters are T0 = 141.1 K, T1 = 25.6 K and σ0 = 37.16 S/cm. One feature attributed to weak localization in SFMO ceramics is the decrease in resistivity in the temperature range between 405 K and 590 K [50]. This resistivity behavior is considered more in detail below. ...
The fitting range of 5970–6020 eV is marked by vertical dotted lines. Also shown are the spectra of the relevant model or reference compounds (chromite represents the starting ore material; FeCr-3 represents Cr3C2). Table 2. Elemental distribution of Fe and Cr in the ferrochrome alloy ...
