A surface enhanced Raman scattering (SERS) active substrate which offers a high enhancement factor (EF), homogeneity, and reproducibility, and which contains silver nanotriangles distributed over large area is fabricated using a low-cost, non-conventional nanoimprinting technique.

We constructed a series of pH-triggered iMNAzymes/TNAzymes exhibiting tunable catalytic performance by regulating the pH of reaction conditions. These molecules can act as devices to control DNA-walking rates through modulation of solution pH within an interval of pH 5.6 to pH 7.4. Furthermore, pH modulation can manipulate a DNA tetrahedron to open at pH 6.4 and remain closed at pH 7.4.

The pattern-transfer ability and effectiveness of different etch masks (NiO, Ni, and ZnO) to fabricate horizontally and vertically aligned uniform Si nanowire arrays is demonstrated over large substrate areas with controlled placement and density. A simple block-copolymer inclusion technique was used to prepare spatially and dimensionally controlled hard-mask nanopatterns on the substrate.

The preparation of nitrogen-doped flower-like porous carbon material from a bio-derived carbon precursor was directed by MgO hydrolysis, and this material exhibited potential as a support for catalytic hydrogenation reactions.

Silicon-based chamfer nanocylinder arrays (CNCAs) are fabricated by carrying out secondary inclined etching of silicon nanopillar arrays. The interaction of the oil droplet with the CNCAs indicated underwater superoleophobic wetting behavior. The structure of the CNCAs could be easily modified in order to prepare chemically heterogeneous structures exhibiting amphiphobic properties without changing their anisotropic wetting ability.

We demonstrate an alcohothermal approach for fabricating NiFelayered double hydroxides (NiFe-LDHs) with dehydrated galleries. The proposed mechanism for this process involves incomplete hydrolysis of urea for simultaneously precipitating metal ions. This methodology is also applicable for fabricating Fe-based LDHs (NiFe-LDH and NiCoFe-LDH) nanoarrays, which exhibit excellent electrocatalytic performance in the oxygen evolution reaction.

The electrochemical performance of nickel sulfide nanoparticles as the anode material of sodium-ion batteries can be dramatically improved by growing them on a percolating carbon nanotube network, and stabilizing them with an ultrathin carbon protection layer.

H2 decorated Ce2 and Ce3 clusters in an scanning tunneling microscope (STM) junction form new objects that behave differently from both H2 molecules and bare Ce clusters; their conductance is controlled by charging and switching at a specific inelastic mode of the pinned H2.
