In this study, Flake-like magnesium hydroxide (Mg(OH)2) and cubic-like aluminum hydroxide (Al(OH)3) nanostructures were synthesized via a simple co-precipitation method at relatively low temperature. Chemical properties and surface morphology of the magnesium hydroxide and aluminum hydroxide were characterized by X-ray diffraction analysis (XRD), scanning electron microscopy image (SEM), transm...

We show improved approximation guarantees for the traveling salesman problem on cubic graphs, and cubic bipartite graphs. For cubic bipartite graphs with n nodes, we improve on recent results of Karp and Ravi (2014) by giving a simple “local improvement” algorithm that finds a tour of length at most 5/4n − 2. For 2-connected cubic graphs, we show that the techniques of Mömke and Svensson (2011)...
