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...

Bu çalışmada ilk etapta doğal (H-Zt), kimyasal şartlandırma yapılmış (KOH-Zt) ve sonrası Fe3O4 manyetik nanopartiküller ile yükleme (KOH-Zt/Fe3O4) olmak üzere üç farklı klinoptilolit Cu(II) giderimi konsantrasyon pH’ya bağlı olarak araştırılmıştır. Ardından en iyi verim alınan adsorbent KOH-Zt çalışmalara devam edilerek, temas süresi, başlangıç metal konsantrasyonu, dozajı sıcaklığın etkisi KOH...

Biodiesel industry requires a cheaper and economical viable raw material that can replace the vegetable oil. Waste from animal and plant sources became the main option due the availability and cheap. In this study, coconut waste is used to produce biodiesel using methanol, acid sulfuric and KOH. In situ process is used, where all the catalyst, reagent and raw material is mixed together in one s...
