Daily Output Improvement of Solar Stills Using Nanomaterials
Solar stills play a crucial role in the rate of production and thermal performance in solar desalination. Several experimental modifications have been attempted to enhance the productivity of solar stills. One of the modifications proposed in recent studies involves the inclusion of nanomaterials in the base fluid used in solar stills. The addition of nanomaterials has been reported to increase the production rate. Common examples of nanomaterials used to enhance the productivity of different types of solar stills include Al2O3, CuO, ZnO, and TiO2.

Plants' Physiological Responses to Drought and Water Stress
Drought affects several biochemical and physiological processes of plants, such as translocation, respiration, the uptake of ions, photosynthesis, nutrient and sugar metabolism, and phytohormones. Cell membranes can be destroyed, and leaf water potential can be diminished by drought. Furthermore, heavy drought causes the cessation of photosynthesis and metabolic disorders, and it can lead to the death of plants.

Cyanobacteria-Derived Biofuel for Sustainable Future
Cyanobacteria are valuable sources of many novel bioactive compounds, such as lipids and natural dyes, with potential commercial implications. One of the advantages of cyanobacteria is that their biochemical constituents can be modified by altering the source of nutrients and growth conditions.

Backfill Mining Method for Mines in China
Despite China’s position as a global mining powerhouse, tens of thousands of small- and medium-sized mines (SM mines) within the country continue to pose potential safety hazards and environmental pollution risks. Only through the identification of suitable development paths can these mines improve their economic and environmental benefits, ultimately driving significant progress in China’s mining industry. Backfill mining, an environmentally friendly mining method, has emerged as a viable solution, offering the potential to ensure mining safety, reduce environmental pollution stemming from tailings stockpiles, and enhance ore resource recovery.

Sustainable Application of Copper-Based Antimicrobial Compounds
Copper-based antimicrobial compounds (CBACs) can control a wide range of plant diseases, such as grape downy mildew, citrus black spot, fire blight of pome fruits, walnut blight, potato late blight, stone fruit canker, coffee berry disease, olive leaf spot, and powdery mildew of many other crops. At present, not considering metal contaminants, CBACs are still at the forefront as the main pesticides sold in Europe.

Toxins and Toxins Secreted by Algal Bloom Habitats
Fish die-offs are important indicators of aquatic environmental problems, and although some fish species are very sensitive to adverse changes in environmental conditions (there are many fish species that have a relatively low tolerance to changes in the environment), it is important to remember that such changes usually affect entire aquatic ecosystems, and thus other animals and plants, as well as everything related to the bottom life of the aquatic environment. Localized sudden and mass fish kills or even whole fish populations and deterioration (mortality) in aquatic life in different types of water bodies, namely freshwater, marine, and estuarine, have been observed quite frequently and excessively. Although the causes of their occurrence may be natural, anthropogenic changes and pollution (including toxins) in aquatic and terrestrial systems are major contributors to the increasing frequency and magnitude of fish kills worldwide.

Renewable Energy Production and CO2 Emissions
The global reduction of carbon dioxide emissions is one of the critical priorities for implementing the Sustainable Development Goals by 2030 and the Paris Agreement 2015. Therefore, it stimulates and increases the ability of countries to implement green imperatives in policies to force the anthropogenic environment, reduce use of fossil fuels, and simultaneously develop alternative energy.

Application of UAV Photogrammetry in Mining Areas
The geological environmental damage caused by coal mining has become a hot issue in current research. Especially in the western mining area, the size of the mining working face is large, the mining intensity is high, while the surface movement and deformation are more intense and wider. Therefore, it is necessary to effectively monitor the surface using appropriate means and carrying out research on the overlying strata structure of the stope.

Indoor Radon Research in Asia-Pacific Region
Indoor radon is a major hazard to human health; it is one of the leading causes of lung cancer. Therefore, radon research in Asia has intensified due to the growing awareness of the harm that radon poses. An analysis of the collected literature data showed that in Asia–Oceania, some regions have—or are believed to have—little indoor radon problems due to climate and low Rn ground. It can be concluded that countries have their own approaches, techniques, and protocols.

Unmanned Aerial Vehicle Remote Sensing
Unmanned aerial vehicle (UAV) remote sensing has been widely used in agriculture, forestry, mining, and other industries. UAVs can be flexibly equipped with various sensors, such as optical, infrared, and LIDAR, and become an essential remote sensing observation platform. Based on UAV remote sensing, researchers can obtain many high-resolution images, with each pixel being a centimeter or millimeter.
