Abstract In this paper, the composition and properties of two different activated calcinated clays were investigated under selected curing conditions. The tendency metabentonite metakaoline to form geopolymers zeolites was by FTIR spectroscopy, TGA DSC techniques, PXRD, HT-PXRD, SEM, BET-N 2 adsorption analyses. selection optimal sample compositions done on a basis preliminary results obtained ...

Current research and development to lower the production cost of biodiesel by utilizing feedstock derived from waste motivates quest for developing catalysts with high performance in transesterification. This study investigates citric acid as a catalyst support transesterification oil black soldier fly (Hermetia illucens) larvae fed on organic kitchen waste. Two were prepared synthesizing NaOH ...

This study explores the tribological performance of microwave-assisted synthesized g-C3N4/MoS2 coatings. The two-dimensional transition metal dichalcogenide (TMD) nanosheet is getting prominence in tribology due to its layered structure. graphitic carbon nitride (g-C3N4) was made using calcination method and nanocomposite with molybdenum disulfide (MoS2) produced a method. structure morphology ...

Abstract The present study was carried out to investigate biodiesel production via transesterification of sunflower oil employing heterogeneous catalyst derived from indigenous ginger (Zingiber Officinale) leaves. It also aims compare the techno-economy performance ginger-based catalysts in 3 different forms viz. calcinated (CGL), activated by KOH (KGL) and NaOH (NGL). plant-based were characte...

The gadolinium substituted nickel-zinc ferrite nanoparticles of the composition, Ni0.5Zn0.5Gd0.05Fe1.95O4 were prepared using sol-gel method. In order to study effect calcination temperature on optical parameters, powder was divided into five parts. first part taken as as-prepared sample and remaining four parts calcinated at different temperatures, 600°C, 700°C, 800°C & 900°C. X-ray diffractio...

Laser Direct Writing (LDW), also known as 3D multi-photon laser lithography of resins, is a promising technique for fabricating complex free-form elements, including micro-optical functional components. Regular organic or hybrid (organic–inorganic) resins are often used, with the latter exhibiting better optical characteristics, well having option to be heat-treated into inorganic glass-like st...

Here, Turkish human hair fibers were used as a carbon source at the synthesis of hair-sourced activated carbons (HHC). During HHCs sodium carbonate (Na2CO3) was added to process for an elevated activation by calcination different temperatures. Then obtained utilized modification paste electrode evaluate supercapacitance performance this HHC. Electrochemical investigation HHC modified electrodes...

Normally, 3D printed objects via photopolymerization usually don’t have fully optimized mechanical properties and functions. In this context, the addition of single filler can improve these through access to composite materials. However, inevitably has a negative influence on light penetration inside composites strongly reducing depth cure. Hence, fabrications photo-composites based combination...

Background and Aims. Tartrate stabilisation is a necessary step in commercial wine production. The traditional method to prevent crystallisation precipitation of potassium bitartrate (KHT) after bottled by adding seed KHT crystals stored tank holding temperatures below 0°C for set period time before bottling. This process requires energy filtration remove sediment. However, compared other techn...
