A multifunctional copolymer with both aldehyde and alkyne groups is synthesized by chemical vapor deposition (CVD) for orthogonal co-immobilization of biomolecules. Surface analytical methods including FTIR and XPS are used to confirm the surface modification. Heparin-binding growth factors [basic fibroblast growth factor (bFGF) in this study] can be immobilized through interaction with heparin...

The successful controlled growth of edge enriched 3D assemblies MoS 2 nanosheets for the fabrication dually selective NH 3 and NO gas sensors using a single step atmospheric pressure CVD method.

The ability to grow high-quality, single-crystal transition metal dichalcogenides (TMDCs) is important for the application of electronic and optoelectronic devices. Here, we report epitaxial growth highly-aligned molybdenum disulfide (MoS2) on c-plane sapphire by chemical vapor deposition (CVD). base edge MoS2 flakes mainly along [11−20] crystallographic orientation sapphire. Structural charact...

We report that nanoparticulate zirconia (ZrO(2)) catalyzes both growth of single-wall and multiwall carbon nanotubes (CNTs) by thermal chemical vapor deposition (CVD) and graphitization of solid amorphous carbon. We observe that silica-, silicon nitride-, and alumina-supported zirconia on silicon nucleates single- and multiwall carbon nanotubes upon exposure to hydrocarbons at moderate temperat...

Semiconducting transition metal dichalcogenides (TMDCs) have attracted a lot of attention recently, because of their interesting electronic, optical, and mechanical properties. Among large numbers of TMDCs, monolayer of tungsten diselenides (WSe2) is of particular interest since it possesses a direct band gap and tunable charge transport behaviors, which make it suitable for a variety of electr...

OBJECTIVE Vascular endothelial growth factor (VEGF) and angiopoietin (Ang)-1 and Ang-2 are mediators of angiogenesis. More recent data suggest that the balance between these growth factors may affect vascular endothelial integrity. Because diabetes is closely associated with endothelial perturbation, we studied plasma levels of these angiogenic growth factors in patients with diabetes; their re...

Chemical vapor deposition (CVD) of hexagonal boron nitride (hBN) using diborane (B2H6) and ammonia (NH3) is reported. The effect growth conditions on hBN rate continuous vs. flow modulation epitaxy (FME) method investigated to gain insight into the role gas-phase chemistry during film deposition. In mode, decreases with increase in temperature, reactor pressure, decrease gas velocity. This attr...

Controlling the detailed structures of single-walled carbon nanotubes (SWNTs) is imperative for realizing many SWNT applications, and understanding the SWNT growth mechanism is important to improve the growth techniques. In the present study, we performed SWNT growth by a catalytic chemical vapor deposition (CVD) method in wide temperature and pressure ranges, using a high-vacuum CVD chamber. W...

The chemical vapor deposition (CVD) method to obtain tailored graphene as a transparent and flexible gas barrier has been developed. By separating nucleation step from growth, we could reduce early graphene nucleation density and thus induce better stitching between domain boundaries in the second growth step. Furthermore, two step growth in conjunction with electrochemical polishing of Cu foil...
