Removal of malachite green dye (MG+), organic pollutant, from wastewater was investigated by photocatalytic method using MnO, NiO and mixed MnO – NiO nano particles (NP’s) prepared from different organic precursors as catalyst. The as – prepared nano oxides were characterized by different physicochemical techniques viz, thermal analysis, FTIR, HRTEM and X-Ray diffraction methods then their

antibacterial and anticancer effects against Breast carcinoma MCF-7 cell line were studied. Three types of oxide NP’s having sizes near to 50 nm were used to find the optimum conditions for photocatalytic degradation and removal of MG+ from wastewater by studying the effect of various parameters on the degradation rate including the catalyst concentration, process duration as well as the catalytic effectiveness of the oxide NP’s. In addition, the effect of UV light sources on the degradation process was studied. The process performed with the nanostructured oxides catalyst was very successfully allowing best degradation of organic compounds. The sorption kinetic and thermodynamic modeling was also studied

We study mutual interplay of information and entropy as quantum field using an information-theoretic (Shannon entropy) complex-vector analysis to calculate, respectively, the Gibbs free energy difference and virial mass. We define conjugate hyperbolic space and entropic momentum co-ordinates to describe these spiral structures in Minkowski space-time, enabling a consistent and holographic Hamiltonian-Lagrangian system that is completely isomorphic and complementary to that of conventional kinematics. Such double spirals therefore obey a maximum-entropy path-integral variational calculus (“the principle of least exertion”. These simple analytical calculations are quantitative examples of the application of the Second Law of Thermodynamics as expressed in entropy terms. They are underpinned by a comprehensive entropic action (“exertion”) principle based upon Boltzmann’s constant as the quantum of exertion.
