چکیده
1. SINGLE PHONON ACCOMMODATION COEFFICIENTS Introduction It is our present purpose to report some recent improvements in quantummechanical accommodation theory. -5 This study will be reported in detail later. The essence of the existing theories may be described as follows. An inert gas atom such as helium, described by an initial wave function '(r), undergoes a collision with a bound surface atom of a lattice described by an assumed harmonic oscillator wave function n(u). A single quantum of energy is transferred in the process. The final state of the atom is taken to be (r), and that of the metal atom nil1 (u). The matrix element for the process is given by

Tensile and Physical Properties of Linear Low Density Polyethylene-natural Rubber Composite: Comparison between Size and Filler Types
Linear Low Density Polyethylene-Natural Rubber (LLDPE-NR) composites in the ratio of 70:20 were made with different loadings of nanosilica and micro-scale Palm Oil Fuel Ash (POFA). Linear Low Density Polyethylene grafted with maleic anhydride (LLDPE-g-MAH) of 10 wt% was added as a compatibiliser. The composites were produced by using two-roll mill machine. The tensile properties of the composit...
متن کاملThe evaluation and comparison of thermo-physical, chemical and biological properties of palladium (II) complexes on binuclear diamine ligands with different anions using the DFT method
As cancer is the top killer diseases in the world, the scientists and researchers have been searching the new drugs and remedy methods. Most of the anticancer drugs are organic compounds which were approved by the FDA while metallodrugs are very rare. In the present time, some palladium and rhodium complexes are going to use as anticancer molecules. The palladium (II) complex has higher antican...
