The growth of a submonolayer of metallic Mo prepared by chemical vapor deposition (CVD) of Mo(CO)6 on Au(111) was studied by scanning tunneling microscopy (STM). At low coverage, nanoscale Mo clusters grow at the elbow sites and in the fcc regions of the reconstructed Au surface. When the coverage increases, rather than decorating uniformly all elbows as found in physical vapor deposition (PVD)...

We present the nanocomposite carbonaceous-palladium (C-Pd) thin films prepared by physical vapor deposition (PVD) and chemical vapor deposition (CVD) methods. Scanning electron microscope (SEM) and transmission electron microscope (TEM) methods were used to study the topography, morphology and structure of carbon and palladium nanograins contained in these films. The quantitative analysis of th...

The field of active colloids is attracting significant interest to both enable applications and allow investigations of new collective colloidal phenomena. One convenient active colloidal system that has been much studied is spherical Janus particles, where a hemispherical coating of platinum decomposes hydrogen peroxide to produce rapid motion. However, at present producing these active colloi...

With the development of smart electronics, a wide range techniques have been considered for efficient co-integration micro devices and energy sources. Physical vapor deposition (PVD) by means thermal evaporation, magnetron sputtering, ion-beam deposition, pulsed laser etc., is among most promising such purposes. Layer-by-layer all solid-state thin-film batteries via PVD has led to many publicat...

Abstract In general, Physical Vapor Deposition (PVD)-TiN coated High Speed Steel (HSS) endmills used to machine carbon steels can perform better at high cutting speeds compared with uncoated tools resulting in better surface finish and longer tool life. Flank wear is believed to be the main wear type that leads to shorten the life of these cutting tools. In this study, the roles of the coating ...

Fullerene (C60) films were prepared on Si, ITO, and Cu substrates by the physical vapor deposition (PVD) method. It was observed that the morphology and structure of fullerene films strongly depend on the substrates. Along with the interactions between fullerenes and substrates increasing from ITO, Si to Cu substrate, C60 forms small polycrystalline grains, large polycrystalline grains and full...

We report a study of nanoribbons of quercetin, a phase I clinical trial anticancer drug, and their inhibitory effects on cancer cell proliferation. Novel quercetin nanoribbons have been prepared by atmospheric pressure physical vapor deposition (PVD). The nanostructures have been characterized by optical microscopy, scanning electron microscopy, transmission electron microscopy, and Raman spect...

In this investigation, Ti/TiN nanolayer and TiN single layer coatings were coated on substrate of AISI 316L stainless steel by applying physical vapor deposition (PVD) using the type of cathodic arc evaporation (CAE). The evaluation of microstructure were carried out using x-ray diffraction (XRD), nanoindentation, atomic force microscopy (AFM) as well as scanning electron microscopy (SEM). Pola...

Abstract To prevent volcanic ash corrosion using thermal barrier coatings (TBCs), a novel method Al 2 O 3 -modification was proposed to reduce molten CMAS wettability on TBCs surface through lotus effect. Plasma spray-physical vapor deposition (PS-PVD), third-generation for fabrication, adopted deposit 7YSZ with feather-like microstructure. Then, modification introduced fabricate dense overlay ...

While it is being debated whether Cd vacancy is an effective p-dopant in CdTe, and whether CdTe thin film in solar energy application should be Cd-deficient or Cd-rich, in the theory of CdTe physical vapor deposition (PVD) it has been assumed that both the source material and the thin film product is stoichiometric. To remediate the lack of effective theory, a new PVD model for CdTe photovoltai...
