Porous carbon nanosheets (aCS) formed by carbonization and chemical activation of biomass cornstalk are presented for capacitive energy storage. The obtained carbon possesses a two-dimensional (2D) sheet-like structure which is mainly composed of abundant micropores. Depending on the amount of KOH used in the activation step, the specific surface area of the carbon sheets varies from 388 to 173...

Pseudocapacitance is commonly associated to the reversible redox reactions from electrode materials, but the enhancement in pseudocapacitance that only relies on electrode materials is limited. Here, we explore the possibility of enhancing pseudocapacitance through both Co(OH)₂/graphene nanosheets (GNS) electrode and K₃Fe(CN)₆ electrolyte. With a good conductivity and favoring electron transfer...

Abstract The current study aimed to improve the extraction of sunflower oil by exposing an ultrasonic treatment at a frequency 20 Hz for different (0,5,10,15)minute, then extracting using hexane. It was noted through results obtained in that there is significant increase rate, it found highest rate (68.96%) time (10min) and lowest (22.50%) (0). physicochemical properties were studied, showed no...

Large amounts of septic tank sludges from sanitation facilities are either landfilled or illegally dumped into the natural environment, leading to environmental pollution and waste resources. This issue calls for advanced methods recycle such as sustainable adsorbents phosphorus, e.g., in agriculture, context circular economy. Here, we hypothesized that alkaline sludge biochar could be an effic...

seeds of nine sugar beet lines: five drought tolerant, two susceptible, and two medium tolerant were washed, sterilised, dried, and sown in water agar medium for germination test. seedling growth characters such as cotyledon fresh weight (cfw), cotyledon dry weight (cdw), root fresh weight (rfw), root dry weight (rdw), and root length (rl) were determined after the end of 28 days period of expe...

Abstract Despite all current efforts, climate change is the greatest challenge of 21 st century. Since existing measures will fail to prevent critical tipping points from being reached, in addition terrestrial geoengineering methods, efforts are underway explore new ways implement space-based methods into short-term construction a buffer solution - International Planetary Sunshade (IPSS). The I...
