Abstract Raising photoelectric conversion efficiency and enhancing heat management are two critical concerns for silicon-based solar cells. In this work, efficient Yb 3+ infrared emissions from both quantum cutting upconversion were demonstrated by adjusting Er concentrations, thermo-manage-applicable temperature sensing based on the luminescence intensity ratio of super-low thermal quenching levels was discovered in an /Yb co-doped tungstate system. The mechanism clearly decrypted as a two-step energy transfer process to . efficiencies, radiative nonradiative transition rates all interested 4 f NaY(WO ) 2 confirmed framework Föster-Dexter theory, Judd-Ofelt gap law, these obtained efficiencies furthermore determined be high 173% : 5 mol% /50 sample.

Increasing Growth of Renewable Energy: A State of Art

Energies, Journal Year: 2023, Volume and Issue: 16(6), P. 2665 - 2665

Published: March 12, 2023

The growth of renewable energy actively takes part in decarbonizing the fossil-fuel-based system. It reduces carbon emissions, footprint, and greenhouse gas emissions increases clean energy. usage resources solves several problems, such as increasing temperature, waste. Every sector contributes to above-mentioned factors environment. One main reasons for this biodegradation climate change is resources. Using instead fossil fuel can solve problem. This paper aims find open research problems about application initiate new innovative ideas regarding A detailed state art includes trends resources, their theoretical evolution, practical implementations. Methodologies used decision analysis are discussed detail. time frame 2010 >2022.

A review of wastewater sludge-to-energy generation focused on thermochemical technologies: An improved technological, economical and socio-environmental aspect

Cleaner Waste Systems, Journal Year: 2024, Volume and Issue: 7, P. 100130 - 100130

Published: Jan. 21, 2024

In response to increasing global waste generation due population growth, urbanization, and industrialization, wastewater treatment operations should shift from being solely energy consumers becoming producers by harnessing sludge (WWS). This approach holds great potential for meeting demands addressing the challenges of treatment. The recovery heat electrical WWS offers a viable solution reduce costs within WWTPs. Thermochemical technologies such as pyrolysis, gasification, combustion hold their efficiency, reaction times, retrieval capabilities. These demonstrate feasibility in terms operational costs, circular economy principles, socio-environmental impact, thanks ongoing advancements waste-to-energy research. review aims explore recovering bioenergy (biogas or syngas) generate energy, including heat, electricity, other innovative products. article provides critical comprehensive examination thermochemical technologies, taking into account technological, economic, factors. It then presents integration techniques that effectively combine anaerobic digestion with conversion enhance syngas, biogas, flue-gas energy. results this study underscore significant sludge-to-energy schemes.

A review of renewable energy resources in Nigeria for climate change mitigation

Case Studies in Chemical and Environmental Engineering, Journal Year: 2024, Volume and Issue: 9, P. 100669 - 100669

Published: Feb. 20, 2024

The reality of climate change is a fact that cannot be disputed. Its impact felt globally on nature and humans. Drought, flooding, delayed or excessive rainfall, extreme heat conditions, rising sea levels, hurricanes, etc. Have been linked to global warming change. Anthropogenic activities, especially in energy exploitation, are major source greenhouse gases (GHGs) driving As such, combat change, continued sourcing from fossil fuels with the emission must replaced by cleaner renewable (RE) options. Climate its effects phenomenon require concerted effort all nations combat. Nigeria one countries most affected given frequent floodings other related disasters. Also, signatory Paris Accord. However, country facing severe electricity shortages necessitating increased use fuels. How can meet commitment mitigation need country? This paper reviews current situation Nigeria, Nigerian RE program, sources initiatives, challenges technologies proposes way forward. study identifies potentials like wind, biomass, hydro, solar technologies, how they could harnessed for mitigation. Increasing such will drastically cut off emissions carbon dioxide stem In conclusion, enumerates recommendations conserve present generated using energy-efficient products practices.
