Rare Earth Elements
The use of analytical techniques is important and critical in all areas related to REE (Rare Earth Elements), such as basic fundamental research, exploration, mining, extraction, and metallurgical activities at different stages by different industries. At every stage of these activities, rock, ore, minerals, and other related materials have to be analyzed for their REE contents in terms of elemental, isotopic, and mineralogical concentrations using different analytical techniques.

Satisfaction with Sustainable Tourism, Vojvodina Province
The goal of researching the development of sustainable tourism in protected areas, which are trying to be tourist destinations, is to gain ecological, socio-cultural, and economic benefits for residents, visitors, and stakeholders. This means that residents, visitors, managers, and state services should be directly involved in the planning and implementation as important bearers of tourism development planning.

Microalgae as Biofertilizers in Modern Agriculture
Due to the constant growth of the human population and anthropological activity, it has become necessary to use sustainable and affordable technologies that satisfy the demand for agricultural products. Since the nutrients available to plants in the soil are limited and the need to increase the yields of the crops is desirable, the use of chemical (inorganic or NPK) fertilizers has been widespread, causing a nutrient shortage due to their misuse and exploitation, and because of the uncontrolled use of these products, there has been a latent environmental and health problem globally. For this reason, green biotechnology based on the use of microalgae biomass is proposed as a sustainable alternative for development and use as soil improvers for crop cultivation and phytoremediation.

Carbon Dioxide Separation Technologies
Carbon dioxide (CO2) emissions from burning fossil fuels play a crucial role in global warming/climate change. The effective removal of CO2 from the point sources or atmosphere (CO2 capture), its conversion to value-added products (CO2 utilization), and long-term geological storage, or CO2 sequestration, has captured the attention of several researchers and policymakers.

Use of Electrocoagulation in Wastewater Treatment
Electrocoagulation (EC) is a wastewater treatment method based on chemical reactions between a coagulant formed under the influence of an electric current released from a given electrode. Electrocoagulation is a technology that properly combines electrochemistry, coagulation, and flotation (or sedimentation). This technology consists of four main stages: electrolytic reaction on the surface of the electrode, formation of metal hydroxides (coagulants), adsorption of soluble (colloidal) particles on coagulants, and removal by sedimentation or flotation. Reactions between the coagulant and pollutants lead to precipitation of sediments which are removed by sedimentation or flotation.

Polyethylene Terephthalate Recycling Techniques
Polyethylene terephthalate (PET) is a widely used thermoplastic with excellent properties, making it a popular choice for various packaging and single-use plastic products. Its exceptional tensile strength, processability, transparency, thermal stability, barrier properties, toughness-to-weight ratio, and chemical resistance have contributed to its widespread use. However, the significant consumption of PET has led to a substantial amount of PET waste, especially in the form of single-use packaging. This has raised concerns about the environmental impact of plastic waste, such as marine pollution and landfill accumulation.

Sensing Travel Source–Sink Spatiotemporal Ranges
Urban remote sensing is providing increasing theoretical and empirical evidence for addressing urban issues, such as traffic systems, medical health, and green spaces. Plentiful image remote sensing technologies have effectively supported the large-scale detection of urban facility distribution. However, cities do not entail only the coverage distribution of buildings, impervious surfaces, parks, and other facilities on the land, but also complex human activities among these urban facilities. Correspondingly, the sensing of human activity phenomena is an emerging exploration in urban remote sensing. The travel source–sink phenomenon is a typical urban traffic anomaly that reflects the imbalanced dissipation and aggregation of human mobility activities. It is useful for pertinently balancing urban facilities and optimizing urban structures to accurately sense the spatiotemporal ranges of travel source–sinks, such as for public transportation station optimization, sharing resource configurations, or stampede precautions among moving crowds.

Ecological Compensation and Ecosystem Function Offsets
Ecological compensation, which is widely applied, is presumed to be an important mechanism to address environmental degradation that commonly occurs due to activities related to development projects and resource use. In comparison to carbon offsets, the implementation of biodiversity offsets are more challenging due to difficulties in biodiversity measurement, determining ecological equivalence, the relatively longer time taken, the higher level of uncertainty, the uniqueness of ecosystems, and the irreversibility of species loss. Generally, there is a positive relationship between biodiversity and carbon stocks; however, there are also cases where there are no clear or even negative relationships between biodiversity and carbon stocks. Ecosystem functions are directly or indirectly affected by environmental degradation, and ecological compensation measures usually compensate for only a few components of the ecosystem functions.

Food Waste Valorisation Techniques
Food waste valorisation techniques aim to convert food waste into value-added products that can be integrated into various stages of the food supply chain. Some sustainable techniques for food waste valorisation include composting, anaerobic digestion, bioconversion, and upcycling.

IoT-Cloud-Based Earthquake Early Warning Systems
Earthquake early warning systems (EEWS) are crucial for saving lives in earthquake-prone areas. Earthquake early warning systems rely on a variety of advanced signal processing techniques and specific parameters to detect and analyze seismic waves in real time.
