We provide a brief introduction about photocatalysis and the reaction mechanism for charge-carrier dynamics focusing in the situation and application of Time Resolved Microwave Conductivity (TRMC) as a useful characterization technique of irradiated semiconductors.

We propose a possible relation between complex networks and gravity. Our guide in our proposal is the power-law distribution of the node degree in network theory and the information approach to gravity. The established bridge may allow us to carry…

In this article,we present the approximate solution of the D-dimensional Schrodinger equation for deformed generalized Deng-Fan plus deformed Eckart potential using parametric Nikiforov-Uvarov method. We obtain the bound state energy eigenvalues and the corresponding wave function for arbitrary l state.…

A generating function for the spherical harmonics in three or more dimensions is given. This function allows us to find in a simple manner the explicit expressions for the spherical harmonics in three dimensions. The generating functions for the spherical…

We carried out measurements of thermal conductivity in a crystal quartz substrate (900 ¡m thick) at temperatures of 1.4 K by using a pumped 4He cryostat. We applied a varied input power from 0.1 up to 1 mW to the…

We present some examples of mechanical systems such that given n constants of motion in involution (where n is the number of degrees of freedom), we can identify a coordinate system in which the Hamilton-Jacobi equation is separable (or R-separable),…

In this paper an optimized fifth algebraic order symplectic integrator is produced. The development of the new scheme is based: (1) on a new set of conditions for symplectic k-step schemes with order up to five and (2) on the…

We derive a new analytic prescription for the density of the non-singular, isothermal, self-gravitating sphere. The proposed prescription gives the density stratification for all radii with a maximum error of ≈1%. This is an improvement over previous prescriptions, which only…

Approximate partition functions and their derivatives for diatomic molecules are formulated taking into account the finite number of levels. A procedure is developed to derive compact analytic expressions, without free parameters, necessary for the efficient evaluation of some thermodynamic coefficients…

Gustave Charles Bonaventure Chancel (1822-1890) worked on problems related to analytical chemistry, wine industry, and organic chemistry. His main findings were on the subject of ketones, their nature, reactions, and derivatives. To his credit are the discovery or synthesis of…
