For the present work, calcite nanocrystals were grown by annealing precursors at 500 °C. These obtained three different thermal schemes. Among these schemes, two involve heating 100 °C for 16 h and + 24 h, respectively. In third scheme, was performed followed 300 h. X-ray diffraction studies, Fourier transform infrared Raman spectroscopic exhibited formation of phase calcium carbonate. Transmis...

Abstract Increasing the surface hydrophilicity of polyetherimide (PEI) through partial hydrolysis imide groups while maintaining length main-chain was explored for adjusting its function in biomedical and membrane applications. The outcome polymer analogous reaction, i.e., degree ring opening chain cleavage, is difficult to address bulk microstructured systems, as these changes only occur at in...
