Power generation using parallel connected microbial fuel cells systems
(India : SRM Research Institute, 2021)
The use of microbial fuel cells (MFCs) for the purpose of obtaining energy from nature has
grown in the second decade of the 21st century. Due to the lack of fossil fuels and less and less available renewable energy ...
Insight and Comparison of Property Improvement in LTA and MFI Zeolite Reinforced Poly(methacrylic acid) Highly Concentrated Composite Hydrogels
(Yuktan Technologies, 2023)
The preparation of zeolite rich polymeric materials presents a challenge due to the zeolite settlingduring synthesis, poor miscibility, the phase separation and generally insufficient interactionsbetween polymers and ...
Pregled katalitičke gasifikacije biomase pogodne za industriju u Republici Srbiji / Overview of catalytic gasification of biomass suitable for industry in the Republic of Serbia
(Belgrade : Society of Thermal Engineers of Serbia, 2023)
Biomasa se smatra važnim obnovljivim resursom, koji igra ključnu ulogu u razvoju održivih energetskih sistema. Biomasa se može pretvoriti u energiju ili vredne hemikalije sagorevanjem, utečnjavanjem, pirolizom i gasifikacijom. ...
