TiO2 has strong photocatalytic activity, which can oxidize and decompose impurities on surfaces and in the air. Therefore, TiO2 is used as an additive in the self-cleaning coating and paint industries. In this work, SiO2 is used in the TiO2/SiO2 mixture as the nucleus to homogenize the dispersion components. TiO2 and SiO2 nanoparticles are synthesized by the sol-gel method combined with ultrasound that suits the size range of 10-30 nm.

A numerical study was carried out to investigate the effectiveness of the charge air cooling method on the exhaust gas emission reduction when applied to a four-stroke marine generator diesel engine at full load. The AVL FIRE 2018a software was used to perform three-dimension (3D) simulations of the combustion process and emission formations inside the engine cylinder operating with various charge air temperatures (CATs).

Three kinds of CueAg composite paste were fabricated. We used 10 mm Cu particles as the main component of the paste as they are significantly cheaper than Ag and Cu nanoparticles. To understand the bonding performance and mechanism, the flake-shape CueAg pastes with a different solvent and a Cu spherical particle with a diameter of 10 mm were separately implemented for the bare Cu bonding.

Ruthenium is one of the most radiotoxic fission products which can be released from fuel as ruthenium oxides in an air ingress accident at a nuclear power plant. In this study it was found that the transport of the released ruthenium oxides through a reactor coolant system into the containment building is significantly affected by the atmospheric conditions.

To prevent endothelium and nerve lesions, tracheal tube and laryngeal mask cuff pressure is to be maintained at a low level and yet be high enough to secure air sealing. Method: In a prospective quality-control study, 201 patients undergoing surgery during anaesthesia (without the use of nitrous oxide) were included for determination of the cuff pressure of the tracheal tubes and laryngeal masks.

Emerging evidence suggested that indoor air pollution caused long-term adverse efects on cognitive function among older adults who spend more than 85% of their time indoors. Although high indoor ventilation can mitigate the efect of indoor air pollution on cognition among the younger population, limited evidence revealed the association between indoor ventilation and cognition among older adults.

The ability of the hyperthermophilic archaeon Sulfolobus solfataricus P2 to grow on organic and inorganic sulfur sources was investigated. A sulfur-free mineral medium was employed with different sources of carbon. The results showed that inorganic sulfur sources display growth curve patterns significantly different from the curves obtained with organic sulfur sources. Combustion of fossil fuels leads to the atmospheric emission of sulfur oxides that contribute to acid rain and air pollution.

The new compounds 7a–k, 8a–k, and 9a–k were synthesized from flavonones 4–6, which can be considered new precursors for quinoline synthesis through a one-step reaction. All the target compounds (7a–k, 8a–k, and 9a–k) were evaluated for their in vitro antimicrobial activity against nine test microorganisms. They showed the most activity against Mycobacterium smegmatis with minimum inhibitory concentrations (MIC) of 62.5–500 µg/mL, indicating their potential uses as antituberculosis agents. Among them 8a–k (m-fluoride) were the most active compounds against M. smegmatis (MIC, 62.5–125 µg/mL).

CO2 adsorption capacities of activated carbon-based adsorbents subjected to different treatments, such as HNO3 oxidation, air oxidation, alkali impregnation, and heat treatment under helium gas atmosphere, were determined by gravimetric analyses and reported previously by our group. In the current work, the experimental adsorption isotherms of these modified activated carbon samples were fitted to Langmuir, Freundlich, and Dubinin–Radushkevich (D-R) models.

The use of multiwalled carbon nanotubes (CNTs) in sol-gel synthesized titanium dioxide (TiO2) photocatalysts as templates was systematically studied. CNTs have high oxidative thermal stability and the controlled removal of CNTs can be achieved at lower temperatures under air flow by the use of Na, Fe, and Co as a catalyst. These catalysts helped to reduce the oxidation temperature of CNTs; thus anatase phase was achieved without significant sintering.

In this report, Raman spectra of the Zn1−xMnxO samples annealed at various temperatures in different ambients, such as in air, in argon and in oxygen were studied. The results indicate that the Raman spectra of the samples are affected significantly by the annealing temperature and by the ambient. The most intensive peak in the Raman spectra at approximately 570 cm−1 has two components, one at around 570 cm−1 (A1(LO)) and the other at 580 cm−1 (E1(LO)). In contrast to previous results, with increasing annealing temperature, the intensity of 570 cm−1 peak still remains anomalously high.

The measurement of fractional concentration of nitric oxide in exhaled air (FeNO) is valuable for the assessment of airway inflammation. Offline measurement of FeNO has been used in some epidemiologic studies. However, the time course of the changes in FeNO after collection has not been fully clarified.

In this work, cold plasma jet system and used it to effectively remove Rhodamine B in the solution. We showed that the main oxidation substance responsible to remove Rhodamine B is the hydroxyl radical (•OH). By studying the effects of – the hydrogen peroxide (H2O2) concentration in the initial and later produced in the solution, the plasma power, and the Ar gas flow speed – on the dye remove rate, we identified 2 main reaction pathways to generate hydroxyl radical (•OH).
