Feb 28, 2017 · XPS studies are performed to deduce the bonding and chemical properties of the BCN thinfilms. Optical band gap (Eg) studies are performed as a result of varying target powers, gas ratios and deposition temperatures.

Sep 1, 2020 · X-ray photoelectron spectroscopy (XPS) is used to analyze the surface chemical compositions of B 4 C@C nanoparticle with core-shell structure as electrode materials of MSCs. The full XPS spectrum survey indicates the existence of B, C and O in the surface of electrodes before and after 50000 cycles test, as shown in Fig. S6 .

Boron carbide (B4C) is one of the few materials that is expected to be most resilient with respect to the extremely high brilliance of the photon beam generated by free electron lasers (FELs)...

4 days ago · B4C films can be coated in a variety of ways. This study was aimed to obtain optimum structural, mechanical and tribological properties of B4C films grown by electrophoretic deposition (EPD) and RF magnetron sputtering techniques. The structural properties of the B4C films were investigated by SEM and XPS analysis.

Feb 22, 2011 · A correlation was observed between surface carbon composition and the bulk toughness and hardness. The C(ls) XPS spectra were utilized to determine the nature of carbon in B 4 C on freshly fractured and Ne + bombarded surfaces. Two distinct peaks were observed in the C(ls) region.
