Degradation Processes for Microplastics
Microplastics (MPs) have been shown to be more hazardous than large plastics. Many studies have confirmed the hazards of MPs to organisms and summarized various MP degradation techniques, but there is a lack of discussion on the prospects of the application of these degradation techniques and their degradation efficiency.

Cathode Materials of Sodium-Metal Chloride Batteries
The widespread electrification of various sectors is triggering a strong demand for new energy storage systems with low environmental impact and using abundant raw materials. Batteries employing elemental sodium could offer significant advantages, as the use of a naturally abundant element such as sodium is strategic to satisfy the increasing demand.

Community Resilience, Adaptive Resilience and Transformative Resilience
Resilience of human systems has increasingly gained ground as both a targeted process of societal development and as a research topic in its own right. As resilience often transcends both the natural and social sciences, it has become a basis for decision-making in studies examining the complex interactions between society, land use management, and policy. While a large body of literature exists on community resilience, there are still significant gaps in knowledge and an imminent need for further research, especially social sciences research.

Food and Livelihood Security for Indonesia’s Smallholders
In Indonesia, smallholders have historically practiced agroforestry. Biodiversity remains crucial for climate resilience, health care, and food security in rural communities. Semi-commercial agroforestry is a midpoint for achieving multifunctional agriculture (biodiversity, soil and water conservation, food security, and income) in the climate change era.

Knife Handle Working Face
With the rapid development of the social economy, the demand for coal is also increasing. Due to large-scale mining in shallow areas, coal resources are being increasingly depleted. Coal mines are gradually being mined in deep areas. Due to the complexity of coal seam conditions and variability, in order to reduce the loss of coal resources and the amount of moving, and to ensure the efficient mining of mines, the knife handle-type working face came into being. The complex overlying rock structure after the mining of the knife handle-type working face has brought great difficulties to the control of the surrounding rock of the working face.

Potential Challenges to Agronomic Biofortification
Agronomic biofortification is the strategy to enhance the micronutrient contents in the edible parts of food crops through the application of mineral fertilizers. Agronomic biofortification can enrich crops with multiple elements, but the most common ones are Fe, Se, Zn, and I. It may be a suitable approach to reach resource-poor rural populations, provided they have access to chemical fertilizers. Soil-to-plant transfer and the accumulation of minerals in the edible portion of food crops determine the success of biofortification. In addition, the bioavailability of minerals from biofortified crops in the body influences the effectiveness of biofortification programs.

Hydrogen Storage for Car Transportation
Hydrogen storage is a key enabling technology for the extensive use of hydrogen as energy carrier. This is particularly true in the widespread introduction of hydrogen in car transportation. Indeed, one of the greatest technological barriers for such development is an efficient and safe storage method.

Remote Sensing and Monitoring of Marine Pollution
With the rapid development of urbanization and industrialization, human activities have caused marine pollution in three ways: land source, air source, and sea source, leading to the problem of marine environments. Remote sensing, with its wide coverage and fast and accurate monitoring capability, continues to be an important tool for marine environment monitoring and evaluation research.

Factors Affecting N2O Emissions from Wastewater Treatment Plants
Wastewater treatment plants (WWTPs) generate significant amounts of greenhouse gases, including carbon dioxide, methane and nitrous oxide. Nitrous oxide (N2O) is an important greenhouse gas with a global warming potential (GWP) 273 times that of carbon dioxide (CO2), contributing to ozone layer depletion and climate change. Therefore, even small amounts of N2O emissions can significantly contribute to total greenhouse gases (GHG) emissions. Thus, it can be concluded that the minimization of N2O emissions and the identification of the factors controlling these emissions constitute a great challenge.

Green Roofs in Urban Areas
The presence of green roofs in urban areas provides various ecosystem services that help mitigate climate change. They play an essential role in sustainable drainage systems, contribute to air quality and carbon sequestration, mitigate urban heat island, support biodiversity, and create green spaces supporting public well-being. Bus stops provide good opportunities for installing green roofs.
