V okviru diplomskega dela smo izdelali protirefleksijske prevleke iz Al2O3 po metodi sol-gel. Za primerjavo smo naredili še prevleko SiO2 po enakem postopku. Prevleke smo nanesli s postopkom potapljanja in jih toplotno obdelali s sušenjem pri različnih temperaturah oziroma s kuhanjem v vreli deionizirani vodi. Protirefleksijske prevleke smo nato an...
95% for MgSO4 and Na2SO4) and organic pollutants (e.g., about 98% for caffeine). High rejection of divalent ions and organic molecules was also observed when a real wastewater effluent was filtered. The influence of the synthesis conditions on the membrane performance is discussed.
Se co-doped bismuth ferrite with graphene oxide nano-sheets is a promising approach for both water-treatment and water-splitting, with better efficiencies of BiFeO3.
50 mol%) in the final product. Annealed alumina-doped particles showed more pronounced shape persistence after annealing at 1000 ∘ C than undoped particles. Quantitative phase analyses revealed an increased stabilization of the tetragonal/cubic zirconia phase and a reduced grain growth with increasing alumina content. Elemental mapping indicated pr...
it yielded the highest X-ray luminescence and thermostimulated luminescence readout of all studied additive concentrations added to alumina during synthesis. Our results show that Cr doped alumina could potentially be used as a promising new material for dosimetry of ionizing radiation.

The present research is focused on developing ZnAl2O4 (gahnite) spinel as an antireflection coating material for enhanced energy conversion of polycrystalline silicon solar cells (PSSC). ZnAl2O4 has been synthesized using dual precursors, namely aluminum nitrate nonahydrate and zinc nitrate hexahydrate in ethanol media. Diethanolamine has been used...

Al doped ZnO (AZO) thin films were prepared on silica substrates by sol-gel method. The films showed a hexagonal wurtzite structure with a preferred orientation along c-axis. Suitable Al doping dramatically improved the crystal quality compared to the undoped ZnO films. Dependent on the Al dopant concentration, the diffraction peak of (0 0 2) plane...
C) and mechanical stability issues, improper porosity and poor capacity. The sol-gel methodology as a promising alternative to address these limitations allowing the production of sorbents with controlled porosity and higher surface area. Thus the combination of molecularly imprinted technology and sol-gel technology can create influential material...

SrTi1−yMgyO3 films were synthesized through sol-gel method on p+-Si substrates. The effects of Mg doping concentration on the microstructure, switching behavior and properties of SrTi1−yMgyO3 films were investigated. All SrTi1−yMgyO3 films are polycrystalline, but the grain becomes coarser, and the number of holes is reduced when the Mg doping cont...
