Article Synopsis
- Researchers developed advanced nanofiltration membranes using a TiO nanofilm created through a vapor-liquid reaction on a ceramic support.
- The process involved reacting glycerol with TiCl vapor to form hybrid films, which were then calcined to create carbon-doped titanium oxide nanofilms.
- These membranes demonstrated high methanol permeability and effective solute rejection, making them ideal for purifying organic solvents.
A humidity sensor for respiratory monitoring based on a tilted fiber Bragg grating (TFBG) functionalized with a nanoporous coating consisting of titanium carbide (TiC) and fullerene (C) is proposed. By incorporating the C into TiC, a nanocomposite film with abundant three-dimensional porousness is coated on the TFBG surface. The nanocomposite film with strong hygroscopicity and desorption properties is highly sensitive to environmental humidity variations, where the induced refractive index changes of the coating result in the spectral responses of TFBG multi-resonances.

The present research aims to develop a Ca-Zn ion-incorporated surface functionalized 3D Ti cancellous bone scaffold for bone defect repair. The scaffold is designed to mimic human cancellous bone architecture through selective laser melting-based additive manufacturing. The chemical-based surface modification approach employed here created a Ca and Zn ions incorporated nano-porous surface layer with enhanced surface roughness and hydrophilicity.

Low-dimensional materials have demonstrated strong potential for use in diverse flexible strain sensors for wearable electronic device applications. However, the limited contact area in the sensing layer, caused by the low specific surface area of typical nanomaterials, hinders the pursuit of high-performance strain-sensor applications. Herein, we report an efficient method for synthesizing TiO2-based nanocomposite materials by directly using industrial raw materials with ultrahigh specific surface areas that can be used for strain sensors.

The role of blood clots in tissue repair has been identified for a long time; however, its participation in the integration between implants and host tissues has attracted attention only in recent years. In this work, a mesoporous silica thin film (MSTF) with either vertical or parallel orientation was deposited on titania nanotubes surface, resulting in superhydrophilic nanoporous surfaces. A proteomic analysis of blood plasma adsorption revealed that the MSTF coating could significantly increase the abundance of acidic proteins and the adsorption of coagulation factors (XII and XI), with the help of cations (Na, Ca) binding.
