Highly ordered vertically oriented TiO(2) nanotube arrays fabricated by electrochemical anodization offer a large surface area architecture with precisely controllable nanoscale features. These nanotubes have shown remarkable properties in a variety of applications including, for example, their use as hydrogen sensors, in the photoelectrochemical generation of hydrogen, dye-sensitized and solid-state heterojunction solar cells, photocatalytic reduction of carbon dioxide into hydrocarbons, and as a novel drug delivery platform. Herein we consider the development of the various nanotube array synthesis techniques, different applications of the TiO(2) nanotube arrays, unresolved issues, and possible future research directions.

Flexible thermoelectric systems capable of converting human body heat or solar heat into sustainable electricity are crucial for the development of self-powered wearable electronics. However, challenges persist in maintaining a stable temperature gradient and enabling scalable fabrication for their commercialization. Herein, we present a facile approach involving the screen printing of large-scale carbon nanotube (CNT)-based thermoelectric arrays on conventional textile.

In the realm of modern materials science, horizontally aligned carbon nanotube arrays stand as promising materials for the development of next-generation integrated circuits. However, their large-scale integration has been impeded by the constraints of current fabrication techniques, which struggle to achieve the necessary uniformity, density, and size control of carbon nanotube arrays. Overcoming this challenge necessitates a significant shift in fabrication approaches.

The exogenous bacterial infection and formation of biofilm on the surface of titanium implants can affect the adhesion, proliferation, and differentiation of cells associated with osteogenesis, ultimately leading to surgical failure. This study focuses on two critical stages for biofilm formation: i) bacterial adhesion and aggregation, ii) growth and proliferation. The titanium with well-organized titania nanotube arrays is first modified by nitrogen dopants, then loaded with CuFeSe nanoparticles to form a p-n heterojunction.

A new series of metal-organic nanotubes was constructed through one-dimensional assembly using molecular triangles or molecular squares composed of paddlewheel dirhodium complexes and bidentate axial ligands. The metal-organic nanotubes were significantly different from conventional solid metal-organic framework (MOF) motifs. They exhibit good solubility owing to the branched side chains at their periphery and demonstrate high orientation capabilities in thin films owing to their anisotropic structure.

Natural building blocks like chitins for self-assembling into complex materials have garnered significant interest owing to the inherent and diverse functionalities. However, challenges persist in the assembly of chitin-based composites, primarily stemming from chitin's poor solubility and compatibility. Herein, a quercetin-mediated multiple crosslinking strategy was developed to enhance compatibility by quercetin-mediated interfacial interactions between chitin and inorganic materials, achieving a series of chitin-based composite hydrogels with high performances.
