Assay for lipid peroxides in animal tissues by thiobarbituric acid reaction

TiO2 and other titanium oxide-based nanomaterials have drawn immense attention from researchers in different scientific domains due to their fascinating multifunctional properties, relative abundance, environmental friendliness, and bio-compatibility. However, the physical and chemical properties of titanium oxide-based nanomaterials are found to be explicitly dependent on the presence of various crystal defects. Oxygen vacancies are the most common among them and have always been the subject of both theoretical and experimental research as they play a crucial role in tuning the inherent properties of titanium oxides. This review highlights different strategies for effectively introducing oxygen vacancies in titanium oxide-based nanomaterials, as well as a discussion on the positions of oxygen vacancies inside the TiO2 band gap based on theoretical calculations. Additionally, a detailed review of different experimental techniques that are extensively used for identifying oxygen vacancies in TiO2 nanostructures is also presented.

Hydrogen sensors based on noble metal doped metal-oxide semiconductor: A review

Due to the increasing global population, growing contamination of water and air, and wide spread of infectious diseases, antibiotics are extensively used as a major antibacterial drug However, many microbes have developed resistance to antibiotics through mutation over time As an alternative to antibiotics, antimicrobial nanomaterials have attracted great attention due to their advantageous properties and unique mechanisms of action toward microbes They inhibit bacterial growth and destroy cells through complex mechanisms, making it difficult for bacteria to develop drug resistance, though some health concerns related to biocompatibility remain for practical applications Among various antibacterial nanomaterials, carbon-based materials, especially graphene oxide (GO) and carbon dots (C-Dots), are promising candidates due to the ease of production and functionalization, high dispersibility in aqueous media, and promising biocompatibility The antibacterial properties of these nanomaterials can be easily adjusted by surface modification They are promising materials for future applications against multidrug-resistant bacteria based on their strong capacity in disruption of microbial membranes Though many studies have reported excellent antibacterial activity of carbon nanomaterials, their impact on the environment and living organisms is of concern due to the accumulatory and cytotoxic effects In this review, we discuss antimicrobial applications of the functional carbon nanomaterials (GO and C-Dots), their antibacterial mechanisms, factors affecting antibacterial activity, and concerns regarding cytotoxicity

Review of functional titanium oxides. I: TiO2 and its modifications

Methane decomposition to produce molecular hydrogen and solid carbon was catalyzed by contact with molten KCl:MnCl2 mixtures in a bubble column reactor from 700 to 1050 °C. The apparent activation energy decreased from approximately 300 kJ/mole for pure KCl to 161 kJ/mole in a 67:33 mol % mixture of KCl:MnCl2. At 30% methane conversion, pyrolysis in the KCl:MnCl2 melt at 1050 °C had high hydrogen selectivity (˜99%) in comparison to pure molten KCl (˜90%), which was observed to produce multiple hydrocarbon co-products. The pyrolysis activity of the KCl:MnCl2 melt remained stable for over 30 h and produced a separable, highly graphitic carbon solid that accumulated at the surface of the higher-density salt melt.
