The gas-surface reaction dynamics of NO impinging on an iron(II) phthalocyanine (FePc) monolayer were investigated using King and Wells sticking measurements. The initial sticking probability was measured as a function of both incident molecular beam energy (0.09-0.4 eV) and surface temperature (100-300 K). NO adsorption onto FePc saturates at 3% of a monolayer for all incident beam energies an...

BACKGROUND The integrated therapy of Bufei Yishen granule and acupoint sticking has been used in the treatment of stable chronic obstructive pulmonary disease (COPD) clinically, with remarkable benefits. This study was initiated to observe the effects of the combination of Bufei Yishen granule and acupoint sticking on pulmonary function and morphormetry in a COPD rat model. METHODS Rats were ...

In the scattering of atoms and molecules from surfaces, focusing effects can give rise to a variety of significant features in both the experimentally measured elastic and inelastic scattering intensities. The study of focusing is extended to the case of sticking of atoms upon scattering into the physisorption potential well. It is demonstrated that this focused sticking ~FS! should give rise t...

Since it was first observed, and especially so in recent years, the phenomenon of the so-called "sticking point" in resistance training has attracted a substantial amount of sports and exercise science research. Broadly speaking, the sticking point is understood as the position in the range of motion of a lift at which a disproportionately large increase in the difficulty associated with contin...

In the context of resistance training the so-called "sticking point" is commonly understood as the position in a lift in which a disproportionately large increase in the difficulty to continue the lift is experienced. If the lift is taken to the point of momentary muscular failure, the sticking point is usually where the failure occurs. Hence the sticking point is associated with an increased c...

The sticking efficiencies (alpha) of colloidal particles have been derived from the intersurface potential energy between 2 microm carboxylated polystyrene microspheres and a silica glass plate using the interaction force boundary layer model. The intersurface potential energies were calculated from force-distance data measured using atomic force microscopy (AFM) and from calculations based on ...

We present both experimental and theoretical studies of the sticking of water molecules on ice. The sticking probability is unity over a wide range in energy (0.5 eV-1.5 eV) when the molecules are incident along the surface normal, but drops as the angle increases at high incident energy. This is explained in terms of the strong orientational dependence of the interaction of the molecule with t...

In a molecular beam experiment we have measured the sticking probability of NO at Ni( lO0) as a function of coverage and molecular orientation. The NO molecules in the 2 1 1, H1/212, 1⁄2> ground state are state selected by use of an electrostatic hexapole. The orientation was produced by a homogeneous electric field. The initial sticking probability is found to be higher for N-end collisions. T...
