Microalgae Cultivation Techniques and Growth Conditions
Microalgae, constituting a wide range of photosynthetic organisms, span from fundamental blue-green algae (cyanobacteria/prokaryotes) to complex seaweeds, rendering them one of the most diverse groups in the biological kingdom.

Blue Carbon in Seychelles
Blue carbon has been proposed as a nature-based solution for climate change mitigation through the reduction in greenhouse gases through carbon sequestration. This proposal entails the protection, restoration, and conservation of blue carbon ecosystems such that these systems can optimally provide valuable ecosystem services. Challenges remain in funding the conservation and protection efforts blue carbon systems require to function optimally. The ecosystem services blue carbon systems provide can be capitalised upon through various “payment for ecosystem services” schemes, but these have their own unique challenges to resolve.

The Brazilian Cement Sector
The worldwide cement industry plays an important role in addressing the climate change challenge. Brazil’s cement industry currently has 91 cement plants with an installed production capacity of 94 million tons per year and has started to calculate the net CO2 emissions to achieve a carbon-neutral cement sector by 2050. Accordingly, the carbon dioxide uptake due to mortar and concrete carbonation is subtracted from the carbon dioxide emitted by the chemical reaction for the calcination of lime, i.e., the calcination process performed during clinker production.

DL-SLICER
A novel artificial intelligence (AI)-driven city classification method which provides a homogeneous and unbiased result, employing visual and publicly accessible data focusing on factual circumstances and complex visual causalities. It offers a new perspective in the research domain by developing a deep learning (DL) tool that analyzes visual information from city satellite image patches.

Tomato and Pepper Seeds in Phytopathogenic Bacteria Dissemination
The seed industry plays a crucial role in global food production but it faces a persistent challenge in ensuring the health and quality of seeds, particularly those of tomato and pepper seeds, which represent key seed commodities on the global market. Seeds can serve as potential pathways for the introduction and dissemination of seed-borne bacteria, which may have devastating effects on crop yield, farmers’ remunerability, and food security. Therefore, fungicides and other antimicrobial compounds are extensively used to disinfect the seeds, thus increasing the input of chemicals in the agri-environment.

Biochar Utilization
Carbon (C) in gaseous form is a component of several greenhouse gases emitted during the combustion of fossil fuels. C movement between the atmosphere, land (biosphere and lithosphere), and ocean (hydrosphere) alters the total amount in each pool. Human activities accelerate C movement into the atmosphere, causing increases in temperature.

Ramsar Site Labudovo Okno for Sustainable Tourism
The Ramsar Site Labudovo Okno (LO) is located in Serbia, AP Vojvodina, on the left bank of the Danube. It covers an area of 3733 ha. This wet habitat is valuable for different ecosystems, among which the most important are those inhabited by rare bird species.

Plant Microbial Fuel Cells
PubMed (NCBI) has pointed to an exponential growth of publications on the subject of a “biofuel cell” in the first decade of our century, and this interest persisted throughout the following years. It should be noted that biofuel elements based on microorganisms (microbial fuel cells, MFCs) are a promising technology to produce bioelectricity since they simultaneously solve the problems of contamination with anthropogenic organic waste, which can be used by microorganisms as a source of carbon and energy.

Triboelectric Nanogenerator Network for Harvesting Ocean Blue Energy
The utilization of abundant blue energy in the ocean could greatly contribute to achieving carbon neutrality. However, the unsolved economic and technical challenges of traditional technologies for harvesting blue energy have resulted in slow progress. Triboelectric nanogenerators (TENGs), as a new approach for converting mechanical energy into electricity, have great potential for blue energy harvesting, which can be connected as networks with different numbers of units for varying scales of energy harvesting. Anchoring strategies of devices and networks are also discussed. The development of TENG networks could provide an effective solution for large-scale ocean blue energy harvesting, which can also serve as an in-situ energy station or power source for self-powered systems, supporting various marine equipment and activities.

Air and Particulates in Underground Oil Shale Mine
Particulate matter (PM) in the context of underground mining results from various operations such as rock drilling and blasting, ore loading, hauling, crushing, dumping, and from diesel exhaust gases as well. These operations result in the formation of fine particles that can accumulate in the lungs of mineworkers. The lung deposited surface area (LDSA) concentration is a variant solution to evaluate potential health impacts.
