Summary: A solar light active photocatalyst was developed by coating silver phosphate (Ag3PO4) onto titania-silica (TiO2-SiO2) microspheres. The Ag3PO4 particles covered the surface of the TiO2-SiO2 microspheres, allowing the composites to absorb the entire visible light spectrum. The composite photocatalyst exhibited higher efficiency compared to its pristine counterparts and a benchmark commercial TiO2.

Summary: The presence of antibiotic residues, such as oxytetracycline (OTC), in wastewater effluents has created the need for monitoring trace concentrations to combat bacterial resistance. Surface Enhanced Raman Spectroscopy (SERS) is a promising technique for detecting and identifying low concentrations (ng/L) without sample preparation. A fibrillar support, Titania-Silica doped with silver particles, was developed in the SERS technique for detecting OTC. The doped ceramic fibers showed the presence of silver nanoparticles ranging from 30 nm to dendritic structures larger than 1 μm, depending on the synthesis conditions. The support doped with Ag at 19 V for 30 s exhibited the highest amplification factor (AF) of 44 for the OTC band at 1278 cm-1.

Summary: Titanium dioxide (TiO2), an inexpensive and environmentally friendly photocatalyst, has received extensive attention for its ability to degrade pollutants through photocatalysis. Improving the photocatalytic efficiency of TiO2 involves expanding its photoresponse range and reducing photogenerated-carrier coupling. Element doping can alter the morphology, size, and structure of a heterojunction, leading to enhanced photocatalysis.

Summary: In recent years, enzyme-based biocatalytic systems have gained increasing attention in industrial and applied research. These systems have been applied in sustainable and environmentally friendly production processes in various industries. However, the low stability of enzymes and difficulties in separation, recovery, and reusability have limited their industrial-scale manufacturing. Immobilization and co-immobilization on robust support materials have emerged as valuable strategies to overcome these challenges. By using environmentally friendly bio-polymers and nanostructured materials, multi-enzyme co-immobilization offers improved process efficiency and cost-effectiveness in biotechnological and chemical industries.

Summary: An experimental and statistical analysis was conducted to investigate the effects of six different types of titanium dioxide on various properties of cement composites. The study found that the size and surface area of the titanium dioxide particles significantly influenced the mechanical and rheological properties of the composites. The choice of polymorph also played a role in determining the photocatalytic and antibacterial properties. The results obtained from the experimental design model were highly correlated with the experimental data, confirming that the anatase form of titanium dioxide was the most effective additive for inducing antibacterial and photocatalytic properties.

Summary: One of the key considerations in shaping the antibacterial properties of nano-mixed cementitious composites is the proper dispersion of zinc oxide nanoparticles in the cement matrix. This study utilized a two-stage modification process, involving both dry mixing and the addition of a superplasticizer, to achieve better dispersion of zinc oxide in the cement matrix. The results showed that combining mechanical and ultrasonic mixing resulted in the most homogeneous mixture, while composites obtained solely through mechanical mixing exhibited better antimicrobial properties.
