The purpose of this study is to investigate how a tracking indirect solar dryer (SD) powered by photovoltaic cells affected the drying kinetics (DK) and thermo-environmental conditions tomato slices. In current investigation, three air speeds (1, 1.5, 2 m/s) are used, as well slice thicknesses (ST) (4, 6, 8 mm) two SD, one which integrated with fixed collector motion (FCM) another SD (TCM). obtained results showed that time (DT) isn't significantly change increasing from 1 m/s, may be due many reasons such short DT, high temperature inside room, little difference between exanimated speeds. When ST changed 4 mm maintaining constant speeds, DT for FCM TCM rose roughly 1.667 1.6 times, respectively. addition, coefficient higher than temperature. At 1.5 m/s speed ST, maximum values moisture diffusivity (MD) 7.15×10-10 9.30×10-10 m2/s both systems, During DK, nine models chose best based on R2 lower χ2 RMSE used. findings DK analysis revealed modified term II model fit experimental data various when TF was dried using systems at varying ST. These recorded observations. Where models' varied 0.98005 0.99942 system 0.99386 0.99976 system. Regarding environmental analysis, it found CO2 mitigation per lifetime ranged 5334.9-6795.4 tons 6305.7-6323.3 TCM.

As the world shifts towards a more sustainable future, solar energy has emerged as preeminent and economically feasible alternative to traditional sources, gaining widespread adoption. This study presents reversed circular flow jet impingement (RCFJI) which aims improve performance of bifacial PVT collector. An indoor experiment using simulator assess energy, exergy, economic efficiency RCFJI The was carried out irradiance ranging from 500-900W/m2 mass rate between 0.01-0.14 kg/s. Energy performance-wise, highest photovoltaic achieved 11.38% at 500 W/m2, while thermal 61.4% under 900 both obtained 0.14 kg/s rate. Regarding exergy performance, 47.27 W W/m2 kg/s, 9.67 0.01 Overall, higher is desirable for performance. Meanwhile, point view, lower preferable. Based on findings, optimal 0.06

Fossil fuels drive global warming, necessitating renewable alternatives such as biomethane (or natural gas). Biomethane, primarily produced through anaerobic digestion (AD), offers a cleaner energy solution but is limited by the slow AD process. Biomass gasification followed syngas methanation has emerged faster alternative. This review examines advancements in these processes over last decade (2015–2024), focusing on techno-economic and life cycle assessment (LCA) studies. Techno-economic analyses reveal that production costs are influenced several factors, including process complexity, feedstock type scale of production. Smaller units tend to exhibit higher capital (CAPEX) per MW capacity, while choice efficiency play significant roles determining overall costs. LCA studies highlight impacts for due demands associated emissions. However, integrating hydrogen electrolysis, along with innovations sorption-enhanced (SEG), can enhance system reduce environmental impacts. critically evaluates technical economic challenges, opportunities optimizing production, discusses potential technologies contribute sustainable bioenergy solutions transition low-carbon economy.

Abstract Using diamond wire sawing P-type single crystal silicon as raw material, the study examines effects of different types and concentrations copper salts on texturing surface wafers. The research results indicate that under three salt etching systems, controlled preparation various structures such grid-like, porous, inverted pyramid wafer is achievable. etched morphologies are primarily due to combined oxidizing nature complexing ability anions in salts, well interaction forces between cations affecting deposition nanoparticles surface. This theoretical can lay foundation for high-efficiency solar cells.

Plant materials throughout the world, i.e. biomass, can provide annually roughly 18 x 1015 Watt-hours (6.5 1013 MJ) of energy, considering just residues from agriculture and forestry. However, at least part that amount has higher-valued uses, including being made into durable products, thereby keeping their carbon content contributing to global warming. This review considers circumstances under which it may be advantageous use biomass resources, either alone or in combination with other renewable energy technologies – such as solar wind meet society’s needs, especially for electricity, heating, transportation. There is a rapidly expanding pool published research this area. To slow climate change, rapid maturation most promising needed, followed by widespread early implementation. Of particular interest are synergistic combinations technologies, together way hydrogen, electricity. Another need make high-energy-density liquid fuels, aviation diesel, naphtha. Although some proposed schemes complicated, expected gradually implemented growing component installed capacity coming years.
