Excessive exposure to hydrogen sulfide (H 2 S) and acetic acid (CH 3 COOH) gases is extremely dangerous in a confined space. An effective indoor air pollutant removal porous carbon filter was developed using NaOH impregnated on activated carbon (NaOH/AC) for the adsorption of H 2 S and CH 3 COOH. Activated carbon (NaOH/AC) filter was characterized using various methods, indicating good physical and chemical properties (especially ‐OH functional groups) for the adsorption of air pollutants. The p

In this research, a case study of International Energy Agency Technology Collaboration Programmes, one of the longest operating global energy technology cooperation approaches, is undertaken. Based on logical framework approach, critical factors were identified leading to positive outcomes in energy research and innovation across nations, in line with their goals. An email survey was sent to representatives of participating countries to collect data regarding inputs and outputs, and desirable ou

The hydrogen production over the combination of nuclear fusion and biomass conversion technologies achieves the carbon-negative effect by employing carbon capture and storage technology. Techno-economic analysis on the fusion-biomass hybrid system is performed to understand the hydrogen cost and the cost competitiveness as compared to other existing technologies. Cellulose, hemicellulose, and lignin for biomass are chosen for the techno-economic analysis in addition to the municipal solid waste

Road freight modeling was conducted to project freight flow and greenhouse gas (GHG) emissions in 16 administrative regions of South Korea through 2050. Origin-destination matrices were constructed using a gravity model for each region. The modeling covered seven product categories for both inter-regional and intra-regional freight transportation and was validated using 2017 data. The total future freight flow is projected to increase from 1399 million tons in 2019 to 1701 million tons by 2035.
