Summary: To reduce the global hazards of arsenic, arsenic-containing water needs to be purified. This study synthesized dimensionally stable TNTAs/SnO2/RuO2 anodes for efficient electrocatalytic oxidation of As(III) by successively electrodepositing SnO2 and RuO2 nanoparticles on TiO2 nanotube arrays. The optimized TNTAs/SnO2/RuO2-10 anode exhibited excellent electrochemical stability and longer service lifetime, with an oxidation conversion efficiency of As(III) still maintained at 98% even after 11 cycles of usage.

Summary: This study investigates the electrodeposition of zinc on nanoporous metal oxide titania nanotube arrays (TiO2 NTAs) using a zinc-containing deep eutectic solvent (Zn2+-DES). The morphology and electrochemical properties of the Zn/TiO2 NTAs were affected by substrate morphology and crystallinity, deposition temperature, zinc concentration, and deposition time. The electrodeposition resulted in the formation of two-dimensional zinc nanohexagons on the TiO2 NTAs. The Zn/TiO2 NTAs exhibited improved electrochemical properties and lower impedance, making them a promising material system for implantable electrochemical sensors.

Summary: The performance of interfacial solar-driven water evaporation (ISDWE) technology was enhanced by anodized TiO2 nanotube film and applied voltage on Ti mesh. The water evaporation rate increased from 1.20 kg·m- 2·h-1 to 2.48 kg·m- 2·h-1. The hydrophilic and nanoporous nature of TiO2 nanotube film improved the solar absorptivity and wettability of Ti mesh, thereby reducing the water evaporation enthalpy and achieving a water evaporation rate of 1.98 kg·m- 2·h-1. The applied voltage also enhanced the salt-resistance property of Ti mesh coated with TiO2 nanotube film.

Summary: Highly efficient electromagnetic wave absorption materials with excellent thermal management are urgently needed to solve the problem of electromagnetic pollution. In this study, bead-curtain-like carbon nanotube arrays@cobalt (CNT As@Co) hybrids are designed to enhance the EMW absorption performance. The CNT As@Co-500 sample with an ultra-low filler loading of 2 wt% exhibits optimal EMW absorption properties, with a minimum reflection loss of -36.86 dB at a thickness of 5.5 mm and an effective absorption bandwidth of 5.78 GHz with a thickness of 2.5 mm. This work provides a new paradigm for designing high-performance 3D EMW absorbers with multifunctionality in electronic devices.

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.
