Study of surface kinetics in PECVD chamber cleaning using remote plasma source
… is the resistivity of gases. For example, the bonding energy of N-F in NF3 gas is different from the bonding energy of C-F bonding in C2F6. Experimental result shows that C2F6 + 02 gas requires more power than NF3 gas to dissociate in the plasma due to the different resistivity. The second …

Aspects of Suspension & Emulsion Polymerisation
… of the protective colloid concentration. The bonding energy between the particles in the agglomerate is independent of the protective colloid concentration and is of the order 0.30 x 10~10 dynes per particle pair.<br/><br/>It was shown that under high shear conditions the agglomeration process …

The development of an innovative bonding method for microfluidic applications
… of a microfluidic device for the purpose of bonding and sealing the microfluidic channels. An extensive literature review revealed the benefits of interfacial heating, and both simulations and experimental investigations were used to evaluate a few different methods. Ultimately, a unique …

Morphology-Property Relationships in Polymers: Poly(vinyl Chloride) and Polybutene-1 (Polyvinyl)
… these gels are in the vicinity of the hydrogen bonding energy. The number of molecules involved per junction in the gel was determined to be two. Molecular entanglement and hydrogen bonding rather than crystal formation is suggested to be responsible for gel formation. Gel forming ability and …

Computational investigations of the electronic structure of molecular actinide compounds
… are also introduced. In the second chapter the bonding in mixed MUCl6, MUCl8 2-, NpReCl8 2- and PuOsC NpReCl8 2- (M = Mo, W) systems is investigated and compared with previous work on the M2Cl6, M2C NpReCl8 2- U2Cl6 and U2C NpReCl8 2- systems. The study shows that the total bonding energy in the …

Computer Methods for Investigating Hydrogen-Bonded Equilibria in Alcohols
The general phenomenon of hydrogen bonding is reviewed in relation to O-H groups in alcohols and the use of physical methods, particularly infrared spectroscopy, and computing methods to gain better understanding of the structures arising from the formation of hydrogen bonds.<br/><br/>The infrared …

The integration of computational and spectroscopic information for hydrogen bonded systems
… to better understand the nature of the hydrogen bonding equilibria present. The integrated absorption coefficient of the monomeric O-H stretching mode is calculated as (2.157 ± 0.025)x10<sup>4 </sup>m mol<sup>-1</sup> and the proportion of the components associated with the three principal bands …

Exploration of basis set issues for calculation of intermolecular interactions and density functional theory calculations of vanadium oxide clusters and their reactions with sulfur dioxide
… work focuses on calculation of intermolecular bonding energies of weakly bound systems within the supermolecular method and on issues related to the choice of a basis set for these calculations, in particular size of the basis set, efficiency of 2-electron integral codes, basis set …

Oxygen-oxygen bonds : catalytic redox pathways in energy storage
Introduction: The present understanding of energy - its many forms, and its governing role in the time evolution of physical systems - underlies many of the most fundamental and unifying principles furnished by scientific theories. We are now deeply aware that energy is inherently quantized and is …
