The molecular dynamics of hydrogen-bonding explored with broadband two dimensional infrared spectroscopy
It is no overstatement to claim that hydrogen bonding is the most important intermolecular interaction. On a day-to-day basis, we encounter the peculiar effects of hydrogen bonding in liquid water; however, it is well appreciated that hydrogen bonding is immensely important in many contexts and, in …

An investigation of hydrogen bonded molecular systems using X-ray and neutron diffraction
… been investigations of a variety of hydrogen bonding systems for unusual behaviour such as disordered or migrating hydrogens/protons with both single crystal X-ray and neutron diffraction, crystallisation of a large number of molecular complexes of the chloranilic acid molecule, and examining …

Force microscopy of self-assembled amphiphilic films
… Microcontact printing of non-covalently bonding molecules has not been as extensively studied, with the exceptions of lipid bilayers of phosphatidylcholine and proteins. Chapters 5 and 6 will show results of stamping several types of alkyl derivatives on a model surface (mica). These …

Use of a Synthetic Substrate for Orthodontic Bond Strength Testing
… that have investigated bond strength values of bonding systems. However, due to the variation in the materials and methods employed, it is very difficult and often impossible to make comparisons among data. The use of a substrate as an alternate to enamel for mechanical tests would minimize …

Inclusion properties of hydroxy host compounds
… smaller) within its structure, leaving the bonding systems of both components unchanged. The molecular network and the enclosed species are usually referred to as the "host" and "guest" respectively. The ability of four hydroxyl-containing molecules to form inclusion compounds was studied. …

Hybridisation of dental hard tissues with modified adhesive systems: therapeutic impact of bioactive silicate compounds on bonding to dentine
… and about the drawbacks of contemporary bonding systems. Several studies revealed excellent immediate and short-term bonding effectiveness of etch-and-rinse adhesives, yet substantial reductions in resin- dentine bond strength occur after ageing. Degenerative phenomena involve hydrolysis …
