A Li-CuFe2O4 thin film has a well-defined nanocrystalline structure with a crystallite size of ~17 nm. The TEM and SEM images of the Li-CuFe2O4 thin film show a polyhedron shape of nanoparticles with uneven sizes, resulting in a significant change in its gas sensing characteristics such as sensitivity and sensor response.

Many biomaterials for bone regeneration have recently been produced using thermally gelled curdlan (1,3-β-Dglucan) as a binder for bioceramics. As the human organism does not produce enzymes having the ability to degrade curdlan, it is not clear what is the fate of curdlan gel after its implantation in the bone.

In clay-rich sedimentary rocks, the pore network is considered to play a key role in controlling transport properties. The pore size distribution (PSD) of clay-rich rocks, the geometrical features of the pore network, and the clay content are parameters governing the diffusion process through clay formations.

The final product was characterized by IR, Raman and XRD spectroscopic methods illustrating the presence of pure α-Fe2O3. SEM images of this material revealed a homogeneous morphology of microcube Fe2O3 with a size of about 500 nm. The catalytic activity of cubic Fe2O3 was investigated on the degradation of methylene blue in a heterogeneous Fenton system.

In this paper, synthesis of tetrakis(carboxyphenyl)porphyrin (TCPP) coated cadmium ferrite (CdFe 2 O4) nanoparticles by using L-lysine as an anchor is reported for the first time. The ferrimagnetic CdFe 2 O4 nanoparticles were prepared via the facile self-assembly method of reflux followed by a heating treatment. The obtained magnetic nanoparticles were coated with TCPP in the presence of the amino acid L-lysine by sonication in ethanol and then refluxing for 12 h. The structural characteristics of the products were determined using FT-IR and XRD pattern.

Methyl 4-((9H-(carbazole-9-carbanothioylthio) benzoate (MCzCTB) was chemically synthesized and characterized by FTIR, 1H NMR, and 13C NMR. A novel synthesized monomer was electropolymerized on a glassy carbon electrode (GCE) in various initial molar concentrations of [MCzCTB] 0 = 1,3,5, and 10mM in 0.1M NaClO4/CH3CN and 1M H2SO4. P(MCzCTB)/GCE was characterized by cyclic voltammetry, Fourier transform infrared-attenuated transmittance reflectance, scanning electron microscopy-energy dispersive X-ray, and electrochemical impedance spectroscopy.

Graphene/cobalt–manganese oxides nanocomposites were prepared from their precursor through chemical reduction where NaOH was used as a reducing agent. The obtained GNs/Co-Mn nanocomposites were used as photocatalyst for the photodegradation of Neutral Red Chloride (NRC) dye in aqueous solution under sunlight as a function of time and catalyst dosage. The morphology and photodegradation study was carried out using scanning electron microscopy (SEM) and UV-VIS spectrophotometry, respectively.

This study also showed comparatively higher solubility percentage in ‘BARI TPS-1’ tuber than the other local varieties, suggesting rapid disruption of swollen starch granule and faster starch degradation in TPS than the other local potato starches. Scanning Electron Microscope (SEM) images of starch granule showed rapidly ruptured and clumped starch granules in ‘BARI-TPS-1’ than the others, indicating TPS starch might obtain gelatinization temperature within a shorter period of microwave heating than that of the other varieties.

In this study, effects of graphene oxide (GO) and ZnO nanoparticles on the properties of acrylic polymer (R4152) coating were investigated. SEM images indicated that ZnO nanoparticles distributed uniformly on GO sheets. Hence, GO/ZnO could be dispersed homogenously in the acrylic polymer matrix while ZnO nanoparticles were agglomerated in acrylic polymer matrix in the absence of GO.
