Graphene growth on the same metal substrate with different crystal morphologies, such as single crystalline and polycrystalline, may involve different mechanisms. We deal with this issue by preparing graphene on single crystal Ni(111) and on Ni films using an ambient pressure chemical vapor deposition method, and analyze the different growth behaviors by scanning tunneling microscopy in combination with other methods. Interestingly, we obtained monolayer graphene on Ni(111), and multilayer graphene on Ni films under the same growth conditions. The possible mechanisms for the different growth behaviors are discussed. Especially, the effects of the inevitable Ni grain boundaries on polycrystalline Ni are addressed.

LiCoO2 nanoplates with exposed (001) planes have been successfully synthesized and shown to deliver high rate capabilities in lithium-ion batteries. Although the (001) plane of LiCoO2 is not electrochemically active, the charge/discharge capacity of LiCoO2 nanoplates can still reach 113 mA﹞h/g at 7 C after 100 cycles. The good rate capability results from cracks on the LiCoO2 nanoplates which are perpendicular to the (001) plane and favor fast Li+ transportation.

We report a quantitative detection of the charge properties of few- layer graphene by surface potential measurements using electrostatic force microscopy (EFM). A minor difference in surface potential is observed to mediate a sequential assembly of metal-free phthalocyanine (H2Pc) on monolayer, bilayer and trilayer graphenes, as demonstrated by scanning tunneling microscopy (STM). This abnormal assembly behavior is further investigated by density functional theory (DFT) calculations.

We report a simple one-pot green synthesis of chiral gold nanoflowers (GNFs) with abundant petal-shaped tips in a chiral reduction environment resulting from the presence of chiral guanosine 5'-monophosphate (5'-GMP) and the chiral reducing agent L-ascorbic acid (L-AA). Different reducing agents can impact the shape and chirality of the products and the size and chirality of the GNFs can also be controlled by adjusting the reaction time. The as-synthesized GNFs with good biocompatibility can be used for surface-enhanced Raman scattering (SERS) enhancement, cellular dark-field imaging and photothermal therapy.

In the presence of an external electric field, the Schottky barrier height (SBH) is lowered by the image force, allowing more free carriers to pass through the metal-semiconductor junction and enhancing the screening effect on positive piezoelectric polarization charges. As the strength of the external electric field increases, the piezotronic effect is significantly suppressed and the metal- semiconductor contact finally exhibits Ohmic behavior.

The highly desirable high-magnetization sub-nanostructured Fe3O4 magnets are demonstrated and the physical origins of the high magnetization and chemical states are investigated extensively. The magnetization of 3O4 nano-magnets is tunable by the deterministic control of the grain size and nano-engineering. XAS and SXMCD reveal that the spin flipping of tetrahedral Fe3+ cations enhances the double-exchange interaction and suppresses the superexchange interaction, leading to giant magnetization.

Gold nanorods and single-walled carbon nanotubes, as two model systems, have demonstrated excellent near-infrared (NIR)-light activated specific cancer cell binding and drug delivery via modification of NIR-absorbing nanodrug carriers with ssDNA caged aptamers; these can be dehybridized under NIR laser irradiation and they can regain their structure and cell-binding ability. These NIR-activable cancer-targeted drug delivery systems show a dualtargeting capability, which is realized by exploiting the intrinsic cancer-cell binding ability of aptamers as well as spatially/temporally controllable laser irradiation (e.g., focusing the laser on the tumor at the best treatment time); this is promising for further reduction of non-specific toxicity to normal tissues and enhanced treatment selectivity against tumor cells.

A facile synthetic approach to selectively produce platinum nanowires and octahedra with high yield has been developed. Due to the well-defined {111} exposed facets, one-dimensional confinement effect, and their minimized edge/corner, the platinum nanowires exhibit excellent activity and superior durability towards both the oxygen reduction reaction (ORR) and the methanol oxidation reaction (MOR), compared to that of the zero-dimensional platinum octahedra catalyst and a commercial Pt/C catalyst. This suggests that such platinum nanowires can be used as high-performance electrocatalysts for future practical fuel cell applications.

Transport properties of GeSe and its heterostructures with MoS2 were investigated both experimentally and theoretically. GeSe exhibits a markedly anisotropic electronic transport, with maximum conductance along the armchair direction. Density functional theory calculations reveal that the effective mass is 2.7 times larger along the zigzag direction than the armchair direction. The temperature dependence of the currents in GeSe/MoS2 heterojunction reveal that GeSe and MoS2 have a type-II band alignment with a conduction band offset of ~0.234 eV.

Highly doped single atom catalyst was prepared via a single-step pyrolysis of glucose, dicyandiamide, and inorganic metal salts (Fe, Co, Ni, Cu, and Pt). High-angle annular dark field-scanning transmission electron microscopy (HAADF-STEM) and X-ray absorption fine structure spectroscopy (XAFS) techniques revealed that nitrogen atoms doped into the graphene matrix were pivotal to the stabilization of metal atoms by generating a metal-Nx coordination structure. Single iron-doped hybrid (Fe@N-doped graphene), as a representative, showed an excellent electrocatalytic performance for oxygen reduction reaction. This work provided a feasible approach for the design and fabrication of highly doped isolated metal catalysts with practical applications.

Graphene/ReSe2 heterostructures have been synthesized on Au foils via a facile chemical vapor deposition route. Interestingly, the second-grown ReSe2 preferentially evolves at the interface between the first-grown graphene and the Au substrate, thus providing a clear example of the confined growth of a two-dimensional (2D) material. The edges and domain boundaries of graphene are proposed to be the preferred intercalation pathways for the ReSe2 precursors.

Hexagonal boron nitride nanosheet (h-BNNS) acts as a metal-free electrocatalyst for high-performance artifical N2 fixation to NH3, which attains a high NH3 formation rate of 22.4米g﹞h−1﹞mg−1cat. and a high Faradic efficiency of 4.7% at -0.75 V vs. RHE in 0.1 M HCl. Density functional theory calculations reveal that the unsaturated boron at the edge site of h-BNNS can activate inert N2 molecule and dramatically reduce the energy barrier for NH3 formation.
