Structural and morphological characterization of silver nanoparticles intruded mineral trioxide aggregate admixture as a chair-side restorative medicament: an in vitro experimental study.

Objectives: The aim of this study was to create a rapid admixture of mineral trioxide aggregate (MTA) and silver nanoparticles (AgNPs) for chairside use in clinical settings to remediate the challenges associated with root canal treatment and pulp capping.

Methods: Synthesized AgNPs at ratios of 10 and 25% were added to commercially available MTA to create an admixture. The admixture was subjected to structural and morphological assessment using X-ray diffraction analysis (XRD), Fourier transform infrared (FT-IR) analysis, Raman spectroscopy, and scanning electron microscopy.

Modelling and optimization of biodiesel production from waste fish oil using nano immobilized rPichiapastoris whole cell biocatalyst with response surface methodology and hybrid artificial neural network based approach.

In this study, zinc oxide (ZnO) nano particle immobilized recombinant whole cell biocatalyst (rWCB) was used for bioconversion of waste fish oil in to biodiesel in a lab scale packed bed reactor (PBR). Central composite design and hybrid artificial neural network (ANN) models were explored to optimize the production of biodiesel. Developed rWCB exhibited maximum lipase activity at 15 % (v/v) of glutaraldehyde concentration and 6 % (w/v) of ZnO nanoparticles at pH of 7.
