The ferromagnetic topological insulator $\mathrm{V}:{(\mathrm{Bi},\mathrm{Sb})}_{2}{\mathrm{Te}}_{3}$ has been recently reported as a quantum anomalous Hall (QAH) system. Yet the microscopic origins of QAH effect and ferromagnetism remain unclear. One key aspect is contribution V atoms to electronic structure. Here valence band thin films was probed in an element-specific way by resonant photoemission spectroscopy. signature $3d$ impurity extracted exhibits high density states near Fermi...
Abstract A newly synthesis composite thin films of poly(vinyl chloride) has been refinement with ionic liquid, where PVC dissolved in THF various concentrations IL by casting method to form the films, without any reaction and dangles within matrix. The were examined diffusive reflectance device under wavelength range (238–1300 nm). XRD, EDX, AFM techniques utilized discover structure matrix after additive IL. XRD analysis illustrated amorphous while EDS main composition pure PVC/IL. optical...
One of the earliest manufactured and most frequently used resins is phenol formaldehyde (PF) resin. Even with lesser loadings, their characteristics can be enhanced by addition nano-ZnO. The novel PF/ZnO Nanocomposites synthesis ultrasonic process. optical properties materials modified wide-band gap semiconductor described via UV–vis spectroscopy. Diffuse reflectance spectroscopy (DRS) one possible tool to measure reflected light from powders rough surfaces clearly. Spectra obtained DRS...
Polytetrafluoroethylene (PTFE) was mixed with silicon carbide nanoparticles in various quantities to create thin films. Long-term UV light exposure the PTFE films used study effects of SiC NPs as a photo-stabilizer by assessing changes weight loss and surface shape. Comparing NP concentrations blank film, very little variation seen. AFM optical microscopy were also analyze morphology When additives compared there hard observe any negative brought due photo-degradation. Additionally, surfaces...
The novel PF/ZnO Nanocomposites Synthesis by ultrasonic process. optical properties of materials modified with wide-band gap semiconductor described via UV-Vis spectroscopy. Diffuse reflectance spectroscopy (DRS) one the possible tool to measure reflected light from powders and rough surfaces clearly. Spectra obtained DRS treated Kubelka-Munk function in order describe energy band accurately for pure para hydroxy benzoic acid polymer. is about 4.5eV samples range 3.4 3.3eV; lowest value...
A new derivative of PAM, acrylamide was copolymerized with succinic anhydride, and the reaction product reacted three dyes, anthocyanin, bromophenol, thymol. The prepared polymers were characterized by X-ray diffraction, FT-IR UV-visible spectroscopy, proton nuclear magnetic resonance spectrometry, thermal analysis. spectroscopy showed disappearance two bands near 3450 3380 cm-1 for stretching vibrations primary amine which indicates formation amides. UV-photolysis aqueous solutions...
