Summary: An anodic aluminum oxide (AAO) template is used to prepare highly ordered Co nanowire arrays with smooth and uniform surfaces. The Co nanowires exhibit high coercivity due to their strong shape anisotropy and magnetic dipolar interactions. Heat treatment results in the formation of a Co3O4 (shell)-Co (core) structure, which further increases the coercivity and remanence ratio of the nanowires.

Summary: This work explores the growth kinetics of nickel nanorods inside a commercially available Whatman nanoporous membrane to achieve uniform deposition over a large area. The effect of DC potential and pulsed potential with various duty cycles and solution temperatures is analyzed to control ion diffusion and reduction near the deposition site. The results show that pulse deposition with a small duty cycle is promising for achieving uniform deposition, and changing the pulse duty cycle can result in a sectioned nanostructure. Electron microscopic observation confirms the deposition mechanism involving initial adhesion of nickel ions to pore surfaces, reduction of ions, and formation of a hollow nanotube structure followed by concentric growth to form a solid nanorod structure.

Summary: NiCo2O4 nanowire array on carbon cloth (NiCo2O4/CC) is proposed as a highly active electrocatalyst for ambient nitrate (NO3-) reduction to ammonia (NH3). It achieves a high Faradic efficiency of 99.0% and a large NH3 yield up to 973.2 mu mol h(-1) cm(-2). The superior catalytic activity comes from its half-metal feature and optimized adsorption energy due to the existence of Ni in the crystal structure.

Summary: A study of the interactions between dsDNA and an 1,1'-biferrocenylene-terminated self-assembled monolayer surface revealed that the interaction force is correlated to the oxidation state of the electroactive groups. The electroactive surface produced much stronger interaction forces compared to its nonelectroactive counterpart. This research provides a quantitative model for studying the interactions between polyelectrolyte and charged surfaces in liquid, which has significant implications for applications such as biosensing and nanomotors.
