4. CONCLUSIONS In brief, this study presents the fabrication, characterization of the magnetic NiFe2O4 decorated EG and its excellent performance in adsorptive sequestration of diesel oil (DO) and crude oil (CO) from aqueous solution. The maximum adsorption capacity for DO and CO was found to be about 30.2 g DO and 25.8 g CO per 1 g of adsorben...

4. CONCLUSIONS In summary, AgNPs have been successfully prepared by using GQDs as reducing agent and stabilizer. AgNPs/GQDs hybrid exhibits good performance for colorimetric detection of H2O2 and glucose. The simple fabrication procedure, effective discrimination ability, and low detection limit suggest that the proposed strategy may hold pract...

4. CONCLUSION We have shown for the first time the liquid templating of lightweight CoAl2O4 nanostructured aerogels by chitosan fibrils. A new phenomenon of swelling chitosan nanofibrils in Al3+-contained water was exploited to obtain a neutral aluminum-chitosan aqueous solutions. Our interesting finding is that the lyophilization of the cobalt...

4. CONCLUSIONS We have successfully synthesized WO3 nanostructures with three different morphologies: nanoplate, nanoparticle and nanorod by hydrothermal and acid precipitation methods without using any structure-directing agent. The crystal of WO3 nanostructures transformed from orthorhombic, monoclinic to hexagonal corresponding with the chan...

4. CONCLUSIONS In this study, highly crystalline Co-doped NiTiO3 powders were successfully synthesized via sol-gel method. The presence of Co modifies the optical properties of the NiTiO3 nanocrystalline powders. The substitution Co ions (10 mol.%) into Ni ions in NiTiO3 resulted in decreasing in optical band gap from 2.34 eV to 1.91 eV. The we...

4. CONCLUSION An improved n-In0.53Ga0.47As/HfO2 interface was achieved by Al doping of the HfO2 layer during deposition, resulting in a Dit near midgap close to 2×1012 cm−2eV−1. From this observation, we can conclude that the presence of Al at the In0.53Ga0.47As/HfO2 interface improves the electrical quality of the interface. It may possibly be...

4. CONCLUSION The results of structural analysis of the material showed that K2GdF5:Tb3+ material with the orthorhombic structure was successfully synthesized. The TL glow-curves of K2GdF5:Tb3+ has the simple and suitable shape for the dosimetry applications. The TL sensitivity of K2GdF5:Tb3+ is higher when compared with the CaSO4:Dy common dos...

4. CONCLUSIONS In this study, the gallium and hydrogen co-doped ZnO (HGZO) thin films were fabricated successfully by using DC magnetron sputtering method. The films obtain high electron mobility of 48.6 cm2/Vs, which is due to intra-crystallinity improvement. It is attributed to the reduction of scattering centers, which is suggested by the XR...

. CONCLUSION We successfully fabricated high quality BZT-BCTx material with different Ca-subtituted content. X-ray diffraction spectra of samples showed the change in structure of composite when Ba ions were substituted by Ba. There was a split in peak at 2θ= 44.7o. The dependence of dielectric constant on temperature with different Ca concentr...
