Abstract:
The multiferroic BiFeO3 powders with perovskite structure were synthesized by sol-gel auto-combustion and conventional sol-gel methods, respectively. As-prepared powders were characterized by XRD, SEM and VSM techniques to investigate phase structure, microstructure and magnetic properties. The results show that the pure phase BiFeO3 powders are obtained successfully by sol-gel auto-combustion after calcining at 650°C for 2h and leaching by HNO3. Compared with conventional sol-gel method which got pure phase BiFeO3 powders at 800°C for 3h, the sol-gel auto-combustion technique can get more pur

Sol-gel is an excellent antibacterial agent carrier. Different researchers incorporated various antibacterial substances, including silver nitrate (AgNO3), quarternary ammonium chloride (QAC), and titanium dioxide (TiO2) in sol-gel.

Abstract:
Although the microwave-assisted sol–gel method is quite frequently used for the preparation of oxide nanostructures, the synergism of the reaction pathways is not fully explained. However, state-of-the-art theoretical and practical results of high novelty can be achieved by continuously evaluating the as-synthesized materials. The present paper presents a comparative study of Mn-doped ZnO nanopowders prepared by both sol–gel and microwave-assisted sol–gel methods. The structural, morphological, and optical properties of the as-obtained powders were established and correlated with their newly p

Abstract:
Sol–gel synthesis is used for the fabrication of new materials with technological applications including ceramics for implants manufacturing, usually termed bioceramics. Many bioactive and resorbable bioceramics, that is, calcium phosphates, glasses and glass–ceramics, have been improved by using the sol–gel synthesis. In addition, the soft thermal conditions of sol–gel methods made possible to synthesize more reactive materials than those synthesized by traditional methods. Moreover, new families of bioactive materials such as organic–inorganic hybrids and inorganic compounds with ordered mes

Abstract:
The sol-gel process is a more chemical method (wet chemical method) for the synthesis of various nanostructures, especially metal oxide nanoparticles. In this method, the molecular precursor (usually metal alkoxide) is dissolved in water or alcohol and converted to gel by heating and stirring by hydrolysis/alcoholysis. Since the gel obtained from the hydrolysis/alcoholysis process is wet or damp, it should be dried using appropriate methods depending on the desired properties and application of the gel. For example, if it is an alcoholic solution, the drying process is done by burning alcohol.

Shear ReO3 structure type Mo3Nb2O14 was prepared by both solid state reaction, sol–gel methods, characterized by Powder X-ray Diffraction Patterns (PXRD) and compared the electrochemical cycling performance. Ex-situ XRD studies proved that the structure is retained. Sol–gel sample shows high capacity 175 mAhg−1 after 20 cycles. At C/5 rate, Sol–gel sample shows lower capacity fading 243 mAhg−1, when compared with solid state reaction sample 170 mAhg−1 after 20 cycles. Mo3Nb2O14 shows good cycling behavior. The complete outcome will be discussed based on the charge/discharge cycles.
