Glowing Combustion Synthesis, Characterization, and Toxicity Studies of Na₂CaSiO₄Powders

Abstract

Here, we are reporting the glowing combustion synthesis of Na 2 CaSiO 4 powders for the first time at low temperature. L-alanine was used as reductant, nitrates of sodium and calcium were used as oxidants. Phase evolution and formation was studied using XRD, FTIR, TGA-DTA techniques. Powder morphology and particle size distribution were characterized using SEM and DLS techniques. Results confirms the formation of single phasic, microcrystalline sodium calcium silicate (Na 2 CaSiO 4 phase) in cubic crystal system. Evaluation of hemolysis and MTT tests suggest that Na 2 CaSiO 4 powders exhibit negative response in in-vitro conditions.

Conversion of Biowaste into Larnite by Sol‐Gel Combustion Route for Biomedical Applications

“…Meanwhile, on thermal decomposition of fuel, around 580 J/g heat energy was discharged which leads to product formation. At 845 °C a broad endothermic peak was observed with regards to the crystallization of larnite material at 850 °C [21,28,29,30] …”

Effect of solvent coordination on the structure of β‐diketone‐based vanadyl complexes and assessment of in vitro antidiabetic activity and cytotoxicity

“…MTT assay was performed to determine cell viability as per previous reports . For in vitro studies, the test substance was dissolved in DMEM supplemented with 2% inactivated FBS to obtain a stock solution of 1 mg ml −1 concentration and sterilized by filtration.…”

“…Among the three complexes, although [VO(dbm) 2 ] has been reported, the crystal data of the same compound with DMF coordination cis to oxo group have not yet been reported. The synthesized complexes were tested for their cytotoxicity and antidiabetic activity on select cell lines and finally the order of activity was compared …”

Formation of surface defects by thermal shock method for the improved photocatalytic activity of ZnO nanoparticles

“…Recently, we developed the thermal shock technique, a simple, easy-to-implement method which is based on the thermal treatment of a material during a short time [19,20]. Different from the combustion synthesis method relying on a thermally induced redox reaction between an oxidant and a fuel [21][22][23][24], the thermal shock method is simply an abrupt temperature change of a solid material with appropriate precursors at some high temperatures during a short time, which allows us to forcefully modify the surface of this material without affecting its bulk structure. In fact, due to the short heating time (only 5 min), the modifications caused by thermal shock are likely to be limited to the surface with the formation of surface defects.…”
