ABSTRACT Biomass and biowaste resources can be used to create self‐doped carbon with a distinctive microstructure. Using an economical environmentally friendly method heteroatom‐doped electrode materials excellent electrochemical performance has attracted much attention in the energy storage industry. A novel facile two‐step, low‐cost, eco‐friendly synthesis for Colocasia esculenta peels been developed manufacture activated (CEPAC) as material supercapacitor application. The CEPAC 1:1...
Successful direct route production of silicon nanostructures from diatomaceous earth (DE) on a single crystalline wafer via the magnesiothermic reduction reaction is reported. The formed porous coating 6 µm overall thickness contains as majority phase along with minor traces Mg, evident SEM-EDS and Focused Ion Beam (FIB) analysis. Raman peaks at 519 cm-1 925 were found in both film substrate, significant intensity variation was observed, consistent SEM observation directly nanoflake layer....
Diatom algae are active and efficient photosynthesizing single cell organisms responsible for a quarter of biomass oxygen release on the Earth surface. Diatoms form an enormously diverse class microorganisms possessing stiff strong, durable exoskeletons made from hydrated amorphous silica forming neat 3D nanostructures, displaying hierarchical organization up to scale tens micrometres. In our ongoing research into structure properties diatoms we observed their colonization patterns various...

Carbon black, a nano-porous material usually derived from the pyrolysis of waste tyres possesses varied particle sizes and morphology making it viable for several engineering applications.
Diatomite continues to fascinate the scientific community with widespread applica tion in energy sector. However, these applications have not encompassed all segments. Herein, we report a soft chemistry approach synthesize nanostructured quartz from diatomite for piezoelectric applications. The synthesis parameters will be varied understand effects on structure and formation of quartz. Preliminary results confirm that is siliceous material neat nanoscale morphology. expand range related
We have studied the effect of synthesis methods on structural state and magnetic hysteresis properties NdFe11Ti compound with ThMn12 structure obtained by arc- melting, annealing, melt spinning nitriding. found prolonged high-temperature annealing form a single-phase state. However, grain size alloy after is 1000 times as less which leads to high compared annealing. Nitriding increases hysteretic both spinning.
Carbon black (CB) is a widely available nano-porous material produced from hydrocarbon decomposition via pyrolysis. However, creating carbon materials with specific pore architectures for improved electrochemical performance challenging. Recent attempts have focused on the utilization of diatom frustules as template hierarchical porous structures. Hence, this study explores physical, chemical, and morphological characteristics diatomite-synthesized activated (DSAC) waste tyre their in...
The raw diatomaceous earth from the vicinity of Bitola (North Macedonia) showed low bulk density (0.61-0.69 g/cm3), high-water absorption (75-81%) and porosity (66- 72%). chemical composition was determined with ICP-MS, revealing following results for earth: SiO2 (63.69 wt%), Al2O3 (11.79 Fe2O3 (5.95 MnO (0.15 TiO2 (0.65 CaO (1.51 MgO (2.24 P2O5 (0.13 K2O (1.64 Na2O (0.93 LOI (11.21 wt%).
