Investigation of the Effect of Oxide Additives on the Band Gap and Photocatalytic Efficiency of TiO as a Fixed Film.

The effects of various additives (YO, GaO, and WO) on photocatalytic degradation efficiency under UV light-emitting diodes (LEDs) and the optical properties of TiO Degussa P25 were investigated using ketoprofen and diclofenac, two non-steroidal anti-inflammatory drugs commonly detected in German rivers. Experimental results demonstrated that thin films containing these additives exhibited similar photocatalytic degradation efficiencies as pure TiO, achieving a 30% degradation of ketoprofen over 150 min. In contrast, the YO/TiO thin film showed significantly improved performance, achieving a 46% degradation of ketoprofen in 180 min.

Low-cost test rig for characterization of photocatalytic planar materials using photonically sized UV-A LED light sources.

In the presented studies, a system for the characterization of planar photocatalysts was developed and tested. In the system, reference substances can be studied online with regard to their degradability and adsorption on photocatalytic materials. In order to perform accurate calculations of the quantum and photon efficiency of the catalysts, the LED arrays used were adjusted in their spacing by simulations so that a homogeneous light field is imaged on the catalysts.

Automated and data-driven plate computation for presurgical cleft lip and palate treatment.

Purpose: Presurgical orthopedic plates are widely used for the treatment of cleft lip and palate, which is the most common craniofacial birth defect. For the traditional plate fabrication, an impression is taken under airway-endangering conditions, which recent digital alternatives overcome via intraoral scanners. However, these alternatives demand proficiency in 3D modeling software in addition to the generally required clinical knowledge of plate design.

Floating immobilized TiO catalyst for the solar photocatalytic treatment of micro-pollutants within the secondary effluent of wastewater treatment plants.

Floating immobilized spherical titanium dioxide catalysts were used to degrade micro-pollutants by solar photocatalysis. The degradation of the micro-pollutants was performed in the secondary effluent of a wastewater treatment plant. During the experimental period, the continuous measurement of the solar ultraviolet (UV) radiation intensity was performed.

Antioxidative and Antimicrobial Evaluation of Bark Extracts from Common European Trees in Light of Dermal Applications.

Plant species have developed effective defense strategies for colonizing diverse habitats and protecting themselves from numerous attacks from a wide range of organisms, including insects, vertebrates, fungi, and bacteria. The bark of trees in particular constitutes a number of components that protect against unwanted intruders. This review focuses on the antioxidative, dermal immunomodulatory, and antimicrobial properties of bark extracts from European common temperate trees in light of various skin pathogens, wound healing, and the maintenance of skin health.
