[ 1 ] - Minimum Tenacity of Toroidal graphs

The tenacity of a graph G, T(G), is dened by T(G) = min{[|S|+τ(G-S)]/[ω(G-S)]}, where the minimum is taken over all vertex cutsets S of G. We dene τ(G - S) to be the number of the vertices in the largest component of the graph G - S, and ω(G - S) be the number of components of G - S.In this paper a lower bound for the tenacity T(G) of a graph with genus γ(G) is obtained using the graph's connec...

[ 2 ] - SPION Conjugated Curcumin Nano-Imaging Probe: Synthesis and Bio-Physical Evaluation

In this work, we investigate the loading and conjugation of Curcumin on oleic acid (OA) and citric acid (CA) functionalized iron oxide nanoparticles and its applications in improving contrast in MRI. Magnetic iron oxide nanoparticles (Fe3O4, MNPs) synthesized using the co-precipitation method and characterized by XRD, DLS, FT-IR, VSM and SEM. FT-IR results confirmed functionalization with oleic...

[ 4 ] - Optimized Method for Curcumin Separation from Turmeric Oleoresin

In this work, a novel and modified method for the solvent purification of Curcumin is presented, a composite of normal hexane & 2-propanol solvents was used to separate the fat content and other impurities. The process was modeled considering the response surface methodology as described by the central composite design. The adjusted R-squared was 0.9443 indicating the variation betwe...
