The work reports the synthesis of nickel nanoparticles supported on thermally reduced graphene oxides (rGO) in ionic liquid [BMIm][NTf2] through microwave decomposition reaction. [email protected] with polymer poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) as binder was positively tested for its response towards oxidizing gas nitrogen dioxide (10 ​ppm air), reducing carbon...

Silicon (Si) has been considered a very promising anode material for lithium ion batteries due to its high theoretical capacity. However, high-capacity Si nanoparticles usually suffer from low electronic conductivity, large volume change, and severe aggregation problems during lithiation and delithiation. In this paper, a unique nanostructured anode with Si nanoparticles bonded and wrapped by g...

Cerium is the most abundant of rare-earth metals found in the Earth's crust. Several Ce-carbonate, -phosphate, -silicate, and -(hydr)oxide minerals have been historically mined and processed for pharmaceutical uses and industrial applications. Of all Ce minerals, cerium dioxide has received much attention in the global nanotechnology market due to their useful applications for catalysts, fuel c...

In the present work, we have investigated synthesis of cerium oxide nanoparticles (CeO2 NPs) using Curvularia lunata culture filtrate. The synthesized CeO2 NPs were characterized by TG/DTA, XRD, Raman, PL, FTIR, UV-visible spectroscopy and TEM analyses. The synthesized nanoparticles retained the cubic structure, which was confirmed by X-ray diffraction studies. UV-visible spectrum exhibited a w...

Nitrogen-doped graphene decorated by iron-nickel alloy is introduced as a promising electrode material for supercapacitors. Compared to pristine and Ni-decorated graphene, in acid media, the introduced electrode revealed excellent specific capacitance as the corresponding specific capacitance was multiplied around ten times with capacity retention maintained at 94.9% for 1,000 cycles. Briefly, ...

Graphite oxide (GO) has received extensive interest as a precursor for the bulk production of graphene-based materials. Here, the highly energetic nature of GO, noted from the self-propagating thermal deoxygenating reaction observed in solid state, is explored. Although the resulting graphene product is quite stable against combustion even in a natural gas fl ame, its thermal stability is signi...

BACKGROUND/AIMS Exposure to ionizing radiation can result in bone damage, including decreased osteocyte number and suppressed osteoblastic activity. However, molecular mechanisms remain to be elucidated, and effective prevention strategies are still limited. This study was to investigate whether cerium oxide nanoparticles (CeO2 NP) can protect MC3T3-E1 osteoblast-like cells from damaging effect...
