Summary: The photocatalytic activity of silver-based catalysts with different amounts of molybdenum disulfide were evaluated for the degradation of ciprofloxacin and hydrogen production. The catalyst with 5%Ag@TiO2-P25-5%MoS2 showed the highest degradation rate of 91% and the catalyst with 5%Ag@TiO2 NWs-20%MoS2 showed the highest hydrogen production rate of 1792 mu mol/hg. The silver nanoparticles and MoS2 contributed to the enhanced performance of the catalysts. The stability tests also showed that the selected silver-based catalysts were stable after seven cycles.

Summary: This study investigated the plasmonic Au (1 wt%) catalysts on hydrothermally synthesized TiO2 nanorods. Different sizes of Au nanoparticles (Au NPs) on Au/TiO2 catalysts were obtained by adjusting the mixing duration and calcination parameters. The presence of localized surface plasmon resonance effect was observed in all UV-Vis diffuse reflectance spectra of the catalysts, regardless of the size of Au particles. The study also identified superoxide anion radicals (O2 & BULL;-) as the main reactive oxygen species responsible for the oxidation of bisphenol A (BPA) under visible-light illumination.

Summary: Plasmonic photoelectrochemical (PEC) water splitting has attracted great interest due to its ability to overcome the limitations of semiconductors in terms of light absorption. In this study, a Pt/Ag/TiO2 metal-semiconductor Schottky nanodiode was designed and fabricated as a photoanode to investigate the role of plasmonic hot carriers in plasmonic water splitting. By combining the designed PEC cell system with the nanodiode, it was demonstrated that the plasmonic hot carriers from Ag played a decisive role in the enhancement of photocatalytic efficiency by contributing to the oxygen evolution reaction.

Summary: The recent application of localized surface plasmon resonances (SPRs) in metallic nanoparticles has led to the construction of plasmonic nanohybrids for heterogeneous photocatalysis. By encapsulating an Ag NP core with SiO2 and TiO2 layers, and Au NPs on the outer surface, an efficient plasmonic photocatalyst, Ag@SiO2@TiO2-Au, has been designed to enhance catalytic activity. The structure unit with strong scattering and field enhancement induced by a plasmonic resonator is shown to significantly boost photocatalytic activity for high H-2 production rates under visible light.

Summary: This study investigated the photocatalytic degradation of naproxen (NPX), a nonsteroidal anti-inflammatory drug (NSAID) commonly found in drinking water. Fluorine-doped TiO2 with controlled morphology was synthesized and applied for photocatalytic degradation under UV-vis and visible light. The effect of morphology, specifically the {1 0 1}, {0 0 1}, and {1 0 0} facets, on the photocatalytic activity was studied. Octahedral fluorine-doped TiO2 particles with exposed {1 0 1} facets exhibited the highest photocatalytic activity and achieved complete degradation of NPX after 40 minutes under simulated solar light (UV-vis). HPLC-MS analysis suggested that the presence of {0 0 1} facets in fluorinated decahedral nanostructures hindered the mineralization rate.

Summary: In this study, a 2D/2D TiO2-GO-ZnFe2O4 composite photocatalyst was synthesized using the fluorine-free lyophilization technique and its potential for ibuprofen degradation was investigated. The composite showed enhanced degradation of ibuprofen under simulated solar light and possessed superparamagnetic properties for easy separation. The photodegradation process resulted in the formation of non-toxic intermediates, while photolysis led to the generation of more toxic by-products. Superoxide radicals and singlet oxygen were found to play significant roles in the ibuprofen photodegradation process based on the degradation analysis and electron spin resonance analysis.

Summary: This research paper explores the hypothesis that powdered milk may contain amyloid fibrils. The presence of amyloids in food products has rarely been studied. Various tests were conducted to investigate this hypothesis, and preliminary results showed that commercially available milks do contain fibrils that have characteristics of amyloids. The implications of these findings can be interpreted in both positive and negative ways, as amyloids could be a potential hazard or evidence that fibrils of food proteins are harmless for consumers.

Summary: This study focuses on the use of organic-inorganic hybrid materials for photocatalytic removal of heavy metals from water. The researchers investigated the effect of the morphology of poly (3,4-ethylenedioxythiophene) (PEDOT) on the adsorption and photoreduction of Cr(VI) to Cr(III) under simulated solar light and visible light. They synthesized titanium (IV) oxide/PEDOT composites with different morphologies using a water-in-oil microemulsion method. The composite with PEDOT microvesicular morphology showed the highest efficiency of Cr(VI) photoreduction to Cr(III) and improved photocatalytic activity under visible light irradiation.

Summary: Single crystalline anatase TiO2 microspheres with {001}/{101} facets were synthesized via a facile one-pot hydrothermal method using NaF as a morphology controlling agent. The effects of NaF amount on morphology and photocatalytic activity were systematically investigated. Results showed that microspheres with improved morphology were obtained at a NaF concentration of 0.1 mol/L. Furthermore, the crystal structure and morphology were found to play significant roles in the photocatalytic activity, with TiO2 microspheres achieving a degradation efficiency of 76.4% for Tetracycline hydrochloride within 2 hours. A growth mechanism involving F ion modified Ostwald ripening and oriented attachment was proposed based on the investigation of the growth process.

Summary: Mould fungi pose serious threats to humans and animals, and may be the main cause of COVID-19-associated pulmonary aspergillosis. Common disinfection methods are not effective against fungi due to their high resistance. Photocatalysis has attracted attention for its antimicrobial properties, and titania photocatalysts have been used in various applications. This study presents the efficiency of photocatalytic methods in removing fungi and bacteria, which are risk factors for SARS-CoV-2 co-infection, and suggests that photocatalysis may help prevent the severity of the COVID-19 pandemic.

Summary: For the first time, titania-based photocatalysts with different crystalline compositions and morphology were modified and tested for antimicrobial activity. The antimicrobial inactivation mechanism was found to follow two different pathways, depending on the conditions. The improved photocatalytic activity of the modified samples was attributed to the hindrance of charge carriers' recombination by phosphate anions in the modification.

Summary: Anatase nanoparticles with {0 0 1}, {1 0 0}, and {1 0 1} facets were synthesized and doped with niobium to investigate the self-trapping of excess electrons and their photocatalytic activity. The presence of excess electrons and the structure of the doped anatase samples were confirmed through structural and spectroscopic analyses. The introduced electrons were found to localize on the surface titanium sites only for the {1 0 1} facets. The dopant-introduced electrons can enhance the photocatalytic activity of anatase structures with {0 0 1} and {1 0 0} facets. The dopant effect on photocatalytic activity depends on the exposed facet.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

It is found that biphenylene offers physical stability, rapid release rate, solubility, and bio-compatibilities compared to other nanocarriers. The adsorption of cisplatin on the surface of biphenylene involves charge transfer from cisplatin to biphenylene. The drug is shown to be released at body temperature in an acidic environment. Biphenylene also exhibits excellent cytotoxicity activity and cellular uptake of the drug. Overall, biphenylene shows promise as a potential nanocarrier for cisplatin delivery.
