High quality TiN coated 316L stainless steel can hardly be fabricated by the traditional chemical vapor deposition (CVD) methods because of the formation of HCl (g) corrosive byproduct and phase transformation at high deposition temperature. To address the problem, herein, for the first time a novel TiCl2 precursor is proposed to fabricate TiN coat...
External catalysts are commonly pre-coated on Ti alloy powders for in situ synthesis of carbon nanotubes (CNTs) to resolve the inhomogeneity issue, but their excessive introduction changes the matrix composition. Here, we activated the catalytic function of trace Fe impurity solid solute in Ti-6Al-4V powders to plant CNTs within the Ti-6Al-4V powde...
A uniform core-shell-structured W-coated Al powder was efficiently prepared by using fluidized bed chemical vapor deposition. The deposited W prevented the defluidization of Al powder and thereby enabled the controlled preparation of core-shell powder with different W-contents. Both the shell and activated sintering of the deposited nano-sized W pa...
A major obstacle for the applications of single-walled carbon nanotubes (SWNTs) in electronic devices is their structural diversity, ending in SWNTs with diverse electrical properties. Catalytic chemical vapor deposition has shown great promise in directly synthesizing high-quality SWNTs with a high selectivity to specific chirality (n, m). During ...

Corrosion resistant carbon with enriched electrical conductivity is advantages for long lasting electrochemical device development. In this study, boron-doped carbon microspheres (BCMS) were prepared by a chemical vapor deposition process from p-xylene and boron trichloride, followed by a mild oxidation step to alter their surface properties and po...
Near infrared light (NIR) photodetectors based on one-dimensional semiconductor nanowires have generated considerable interest due to their practical application in versatile fields. We present a facile yet efficient approach to rationally integrating KCu7S4 semiconductor nanowires by the Langmuir-Blodgett (LB) technique. A self-powered near infrar...
As an important semiconductor nanomaterial, InP nanowires (NWs) grown with a typical vapor-liquid-solid mechanism are still restricted from their low electron mobility for practical applications. Here, wnonpolaroriented defect-free wurtzite InP NWs with electron mobility of as high as 2000 cm(2) V-1 s(-1) can be successfully synthesized via Pd-cata...
Recently, owing to the large surface-area-to-volume ratio of nanowires (NWs), manipulation of their surface states becomes technologically important and being investigated for various applications. Here, an in-situ surfactant-assisted chemical vapor deposition is developed with various chalcogens (e.g. S, Se and Te) as the passivators to enhance th...
A simple in situ self-assembly selective synthetic strategy for onestep controllable formation of various three-dimensional (3D) hierarchical Co3O4 micro/nanomaterials with peculiar morphologies, uniform size, and high quality is successfully developed. The Morphological control and related impact factors are investigated and clarified in detail. T...
Controllable synthesis of III-V compound semiconductor nanowires (NWs) with high crystallinity and uniformity is essential for their large-scale practical use in various technological applications, especially for those which are grown on non-crystalline substrates. In this study, the catalytic effect is investigated thoroughly in the growth of vari...
