Bioclcowo 4 heterostructures were obtained via precipitation route for the first time.The prepared heterostructures was active for rhodamine b dye degradation under solar light.An effective transfer and separation of photo induced e h pairs over bioclcowo 4 1 heterostructure was demonstrated by pl and electrochemical impedance spectroscopy studies.H , oh, o 2.
Read MoreA method for measuring the surface energy of solids and for resolving the surface energy into contributions from dispersion and dipolehydrogen bonding forces has been developed.It is based on the measurement of contact angles with water and methylene iodide.Good agreement has been obtained with the more laborious c method.Evidence for.
Read MoreDensity is a derived quantity - we measure two other quantities mass and volume and then calculate density.A first time learner, however, deserves first to understand the concept - and that takes careful teaching and a little time.Moreover, different techniques are required for solids, liquids and gases.Many students imagine that a gas such as air has no mass.
