In this work, the effect of annealing temperature and Cr3+ concentration on the structural and optical properties of the SnO2 host crystals has been investigated. The Cr-doped SnO2 samples were synthesized by a simple hydrolysis method, using SnCl4.5H2O as the host precursor and CrCl3.6H2O as the source of dopant.

Today’s globalised world is well aware that the logistics in fossil fuel industry enables it to be the main contributor to greenhouse gas (GHG) emissions that cause global warming and climate change. Negative public opinion about the oil and gas industry is rising globally. A growing number of societies are proficient at varying public opinion about oil and gas industry emissions. In this context, oil and gas companies have begun to substantially invest in renewable energy sources in a bid to diversify their oil and gas product portfolios to mitigate climate change risks.

In the study, SnO2/ZnO core/shell nanowires were synthesized through the two-step processes. First, SnO2- core nanowires were synthesized from Sn powder source at 750 oC by a chemical vapor deposition method (CVD). The ZnO shell was then deposited on SnO2 nanowires by a DC sputtering method.

Tidal energy is a renewable energy source produced by the rise and fall of ocean tides. Tidal energy can be exploited using a special type of generator that converts tidal energy into electricity. Tidal power generation has the potential to open up many prospects for energy field and minimize carbon dioxide emissions that cause the greenhouse effect.

Photovoltaic energy sources are increasingly in demand due to the cost of petroleum fuels and concerns about carbon emissions. For this reason, it is important to determine the photovoltaic properties of the compounds that are thought to be suitable for these energy sources. Here, 1,1,2,3,4,5-Hexaphenyl-1H-silole (HPS) and 1,1,2,3,4,5-Hexaphenyl-1H-germole (HPG) compounds that are thought to have excellent photovoltaic properties, electronic and charge transport properties were investigated experimentally and theoretically.

Major national emission sources are assessed by characterization of smoke pollution arising due to traditional agriculture, domestic, and cooking activities in the regions of the biggest biomass burning. Measurement campaigns were carried in Son La and Ba Vi regions, Vietnam, during the dry seasons of 2013 and 2015-2016.

In this study, the AERMOD modeling system was used to evaluate the impact of the stack emission by the thermal power plants on the ambient atmospheric environment. The annual average concentrations of these pollutants indicate that the high terrain areas at the south and northwest of Cam Pha City, which block the flow of the stack emission, are the most affected regions by exhausted gases from industrial stacks.

Air pollution is getting worse in Viet Nam in recent years, particularly in big cities. The most important source of pollution are traffic and industrial activities. The paper "A Review on Current Status of Urban Air Pollution in Ho Chi Minh city and Ha Noi" reviews air pollution situation in Ho Chi Minh city and Ha Noi. We also recommend policies to tackle the problem: (i) upgrade the national air quality standard, (ii) install systematic and high-quality network of monitor stations, and (iii) remove means of transport that unmet emission regulations.

Although the western Anatolian region is a foci for hydrothermal systems, this region has several high heat-generating granitic intrusive bodies that qualify to be candidates for enhanced geothermal systems (EGS). Considering the future energy requirement, carbon dioxide emissions reduction strategies, food, and water security issues, these granites appear to be the future clean energy source for the country. One such granite intrusive is located in the Kestanbol area in the western Anatolian region.

The present study sought to clarify the contributions to PM mass of ultrafine, fine (PM2.5), and coarse particles (PM10 – PM2.5) in an urban–industrial area with multiple emission sources. We performed both online measurements of PM at a high temporal resolution and size-resolved offline measurements.

Bioaccessibility and source-specific health risk of heavy metals in PM2.5 in a coastal city in China
Based on the combined positive matrix factorization-health risk (PMF-HR) model, industry, combustion, and traffic emission contributed the most to the health risk of Cr and Cd, followed by soil parent material layer. Our study provided a reliable method to calculate the bioaccessible heavy metal health risk and determine each potential source’s contribution to health risk.
