Multiple characterization techniques, including Fourier-transform infrared, Raman spectroscopy, scanning electron microscope–energy dispersive X-ray analysis, and transmission electron microscope, confirm the formation of phase-pure VS2 nanosheets with a hexagonal structure.

A specific capacitance of 106 F g−1 at a current density of 1 A g−1 is demonstrated using symmetric supercapacitors fabricated using these VS2 nanosheets. Using this device, an energy density of 34 Wh kg−1 at a power density of 800 W kg−1 is achieved.

In this study, different formulation of RCPs is developed such as RCP1, RCP2, RCP3, and RCP4. The real-time cooling capability of all the developed RCPs are experimentally investigated by painting a single layer on asbestos cement sheet and clay tile in indoor and outdoor conditions. Strategic selection of fillers and binders in the development of RCPs maximizes the reflection in solar window and emission in thermal window. During outdoor analysis at a tropical savanna condition, a drastic reduction in temperature of 12.36 °C is observed in RCP3 in a midday and sub-ambient cooling of −3.68 °C observed in nighttime. When compared to commercial white-paint-coated roofs, an excellent reduction of ≈4.3 °C is found with RCP3. Also, RCPs used in this study saves almost 335 Wm−2 of energy on air conditioners by offsetting negative cooling power of commercial roofs (−300 Wm−2) to positive cooling power by 35 Wm−2. Hence, this passive cooling technique saves people from deadly heat waves.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 5","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143939385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research objectives are to enhance the DRM efficiency and reduce coke formation using Ni catalysts supported on Mg-modified Al2O3 in parallel plate dielectric barrier discharge. Raising the Ni calcination temperature from (Ni/Mg–Al2O3-500) to 700 °C (Ni/Mg–Al2O3-700) enhances NiO reduction temperatures, thus diminishing their reducibility. This indicates that Ni/Mg–Al2O3-700 exhibits stronger NiO–Al2O3 interaction, resulting in increased metal dispersion and decreased crystallite and particle sizes. As the Ni calcination temperature increases from 700 to 800 °C (Ni/Mg–Al2O3-800) the intensity of the Ni0.8Mg0.11Al2O4 spinel structure is enhanced. The increased Ni calcination temperature enhances the metal-support sintering processes and promotes the metal nanoparticle cluster formation, leading to increased particle and crystallite sizes, alongside decreased dispersion of Ni and Mg particles on the catalyst surface. The Ni/Mg–Al2O3-700 exhibits lowest NiO reducibility, strongest NiO–Al2O3 interaction, highest metal dispersion, highest specific surface area, smallest particle, and crystallite sizes. Consequently, it attains the highest CH4 and CO2 conversions, H2 and CO selectivities, and energy efficiency, as well as the lowest coking rate, carbon deposition, carbon loss, and specific energy consumption.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 6","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144273371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both NFA-2 and NFA-3 display the high lowest unoccupied molecular orbital energy level, leading to an increased open circuit voltage in the organic solar cells.

The optimized organic solar cells, based on PBDB-T:NFA-2 and PBDB-T:NFA-3 attained power conversion efficiency of 9.24% and 13.50%, respectively. Since the absorption characteristics of NFA-2 and NFA-3 are complementary, a small amount of NFA-2 is added into PBDB-T:NFA-3 binary blend, the ternary organic solar cells attained a power conversion efficiency of 15.24%. The rise in power conversion efficiency is linked to the higher values of both short circuit current and fill factor. The increased short circuit current value in ternary organic solar cells is linked to the efficient use of excitons produced in NFA-2 by transferring energy from NFA-2 to NFA-3 and effective exciton dissociation, faster charge extraction, decreased bimolecular and trap-assisted recombination. The enhanced value of FF is also linked to the processes mentioned earlier.
