Bioaccumulation of Fluoride and Its Microbially Assisted Remediation
Fluoride is widely found in soil–water systems due to anthropogenic and geogenic activities that affect millions worldwide. Fluoride ingestion results in chronic and acute toxicity, including skeletal and dental fluorosis, neurological damage, and bone softening in humans.

Biofuel Production Pathways by Microalga
Using microalgae to treat wastewater as well as simultaneously produce biofuels is one of the approaches for a sustainable future. The manufacture of biofuels from microalgae is one of the next-generation biofuel solutions that has recently received a lot of interest, as it can remove nutrients from the wastewater whilst capturing carbon dioxide from the atmosphere. The resulting biomass are employed to generate biofuels, which can run fuel cell vehicles of zero emission, power combustion engines and power plants. By cultivating microalgae in wastewater, eutrophication can be prevented, thereby enhancing the quality of the effluent. Thus, by combining wastewater treatment and biofuel production, the cost of the biofuels, as well as the environmental hazards, can be minimized, as there is a supply of free and already available nutrients and water.

Shellac and Its Potential in the Packaging Application
Shellac, an insect-derived material, has received the least attention due to its scarcity in south Asia. Currently, Shellac is used in various applications, such as furniture polish, glazing agent for candies and pharmaceutical pills, coating on fruits to increase shelf life, primers, smart sensor, 3D printing, and green electronic. However, the limitations of Shellac such as: brittleness with time, self-esterification, low transparency, solubility in alkaline medium and in most organic solvents have limited its usage in the packaging application. Many of these problems can be improved by physical blending or chemical reaction with other materials to make Shellac more durable, impede self-esterification, and facilitate the film-forming ability, which suggests the potential usage of Shellac in packaging applications.

Amin Beiranvand Pour
My scholarly interests range widely, from mineral exploration to environmental issues such as geo-hazard, structural mapping, geothermal and geomorphic and coastal geology investigations. Subsequently, I have conducted several research projects for geological mapping, disaster management and environmental modeling using a variety of satellite remote sensing data such as the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), Landsat Enhanced Thematic Mapper+ (ETM+), Landsat-8, Advanced Land Imager (ALI), Hyperion and Phased Array type L-band Synthetic Aperture Radar (PALSAR) satellite data in arid and semi-arid terrains, Antarctic, Arctic and tropical environments.

Energy Transition to Achieve Carbon Neutrality
Successful energy transitions, also referred to as leapfrog development, present enormous prospects for EU nations to become carbon neutral by shifting from fossil fuels to renewable energy sources. Along with climate change, EU countries must address energy security and dependency issues, exacerbated by factors such as the COVID-19 pandemic, rising energy costs, conflicts between Russia and Ukraine, and political instability. Central European countries may transition to a clean energy economy and become carbon neutral on economic and strategic levels by locating alternative clean energy supply sources, reducing energy use, and producing renewable energy.

Mekong
The Mekong, or Mekong River, is a trans-boundary river in East Asia and Southeast Asia. It is the world's twelfth longest river and the sixth longest in Asia. Its estimated length is 4,909 km (3,050 mi), and it drains an area of 795,000 km2 (307,000 sq mi), discharging 475 km3 (114 cu mi) of water annually. From the Tibetan Plateau the river runs through China , Myanmar, Laos, Thailand, Cambodia, and Vietnam. The extreme seasonal variations in flow and the presence of rapids and waterfalls in the Mekong make navigation difficult. Even so, the river is a major trade route between western China and Southeast Asia.

Years of Living Dangerously
Years of Living Dangerously is an American documentary television series focusing on global warming. The first season was broadcast in the US in 2014 on Showtime. It won an Emmy Award as Outstanding Documentary or Nonfiction Series. The second season aired on the National Geographic Channel in 2016. Executive producers included James Cameron, Arnold Schwarzenegger, and series creators Joel Bach and David Gelber (formerly of 60 Minutes). Joseph Romm and Heidi Cullen were the chief science advisors. The weekly episodes featured celebrity hosts with a history of environmental activism and well-known journalists with a background in environmental reportage. These "correspondents" traveled the world and throughout the U.S. to interview experts and ordinary people affected by, and seeking solutions to, the effects of global warming. They acted as reporters and proxies for the audience, asking questions to find out people's opinions and to discover the scientific evidence. The final episode of season one featured an interview of President Barack Obama. Episodes explored the effects of rising sea levels, historic droughts and flooding, water scarcity, ocean acidification, deforestation and the rapidly increasing extinction rate of species, but also focused on "solutions that individuals, communities, companies and even governments can use to address worldwide climate change", including cheaper solar and wind energy, advancing battery technology and electric cars. Hosts included Cameron, Schwarzenegger, Harrison Ford, Ian Somerhalder, America Ferrera, David Letterman, Gisele Bündchen, Jack Black, Matt Damon, Jessica Alba, Sigourney Weaver, and various other actors and journalists. Schwarzenegger reflected on how the series tries to make the issue of climate change resonate with the public: "I think the environmental movement only can be successful if we are simple and clear and make it a human story. We will tell human stories in this project. The scientists would never get the kind of attention that someone in show business gets." Cameron elaborated: "We didn’t use our celebrities as talking head experts, because they’re not climate experts. They were concerned, intelligent, curious citizens who were out to find answers. They were functioning as journalists." Newsweek said that the celebrity hosts "lend sparks to an issue that sends most viewers for the exits".
