Special Issue Information

Dear Colleagues,

TiO2 is a non-toxic, low-cost, and chemically stable material that has remarkable catalytic and distinctive semiconducting properties. TiO2 crystals exist in three main crystal structures: anatase, rutile and brookite, and many other minor phases, including monoclinic TiO2-B, columbite TiO2, and ramsdellite TiO2-R. In the last few decades, TiO2 and its nanocomposite materials have been attracting tremendous interest in a wide range of research and application areas, including photocatalysis, sensors, and environmental and energy applications.

We invite researchers to contribute to the Special Issue on TiO2 and its nanocomposite materials, which is intended to serve as a unique multidisciplinary platform covering broad aspects of science, technology and the application of TiO2 and its nanocomposite materials.

The potential topics include, but are not limited to:

  • Synthesis and preparation of TiO2 nanomaterials;
  • Properties of TiO2 nanomaterials;
  • TiO2-based composite materials;
  • TiO2-enhanced coatings;
  • Black TiO2 nanomaterials;
  • TiO2-based photocatalysis;
  • TiO2-based sensors;
  • Environmental and energy storage applications;
  • Other applications of TiO2 nanomaterials.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Crystals is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The present paper presents a gliadin detection method. This method is based on a modified Ti electrode. Modification was performed by a simple and cheap anodization. Then, a layer of graphene oxide was added, and gliadin antibody was fixed on the electrode surface. Using this complex system, electrochemical impedance spectroscopy was used for gliadin detection. Solutions with known gliadin (a fraction from gluten) content were used for analysis. Impedance measured at a certain frequency and coating resistance were analyzed. Better results (good linearity and lower detection limit) were obtained by plotting impedance at a certain frequency versus gliadin concentration. Coating resistance was proved to be in linear dependency with gliadin concentration only at lower concentrations. This system based on titanium nanostructured electrode has the potential to be used for gluten contamination detection from foods. Full article

In this article, a strategy for the fabrication of color-tuned titanium using a torch was developed. The torch was used to manufacture a layer of titanium dioxide on titanium substrates. The reaction time and requirements were reduced compared to the anodization process. Various colors appeared depending on the time of torch heating, and this torched-titanium substrate was treated with octadecyltriethoxylsilane (ODTS) to gain superhydrophobic properties for self-cleaning. Scanning Electron Microscope (SEM), Raman spectroscopy, and Atomic Force Microscope (AFM) were used for surface analysis. Besides, the mechanical and ODTS stability of the surface were evaluated through a cross-cut adhesion tape test and water contact angle measurement, proving that the torch is a suitable fabrication process for multifunctional color-tuned titanium.
