Towards a chemistry of cohesion and adhesion

Progress in Surface Science, 1991
Abstract Modern chemistry frequently describes the structure and reaction dynamics of molecules in terms of the general principle of “competition for bonds”; consequently, bonding forms the basis of the language of chemistry. The actual models used to represent these bonds are frequently system specific.

Chemistry of the calcite/water interface: Influence of sulfate ions and consequences in terms of cohesion forces

Cement and Concrete Research, 2013
Abstract Calcite suspensions are used to mimic the behavior of more complex cementitious systems. Therefore the characterization of calcite–water interface in strong alkaline conditions, through ionic adsorption, electrokinetic measurements, static rheology and atomic force microscopy is a prerequisite.

Functional Control of Peptide Amphiphile Assemblies via Modulation of Internal Cohesion and Surface Chemistry Switch

Chemistry – A European Journal, 2018
AbstractUnderstanding the impacts of the internal cohesion and surface chemistry of supramolecular systems on the collective behaviors in the contacts between the systems and biomolecules can greatly expand the functional diversity and adaptivity of supramolecular nanostructures.

Formation, Chemistry and Fertility of Extraterrestrial Soils: Cohesion, Water Adsorption and Surface Area of Carbonaceous Chondrite. Prebiotic and Space Resource Applications

Icarus, 1999
Abstract Following microbial and plant responses to Murchison CM2 meteorite nutrients, further soil fertility parameters are examined. Cohesion of the matrix is tested by dissolving in acidic disaggregation agents, 0.4 M CH 3 COOH, 10% HNO 3 , H 2 SO 4 (pH 3), 50%H 2 O 2 +H 2 SO 4 (pH 3), and saturated CO 2 solution.

Multicomponent Synthesis: Cohesive Integration of Green Chemistry Principles

2021
The application of multicomponent reactions (MCRs) in the generation of compound libraries has long been recognized as a key strategy for the development of lead matter in drug discovery. Given the numerous advantages that these processes possess not only from the ability to generate large numbers of diverse compounds but also from a sustainability ...

Cohesive energies of NH4Cl and NH4Br

Journal of Physics and Chemistry of Solids, 1970
Abstract The Born Model is used to calculate the room temperature cohesive energies of NH4Cl and NH4Br. The computed values are respectively 155·0 and 148·2 kcal/mole. Comparison with experimental cohesive energies determined from a thermo-chemical cycle shows the predominance of ionic binding and suggests a probable contribution of 4·4 and 4·0 kcal ...

The cohesive energy of TiO2 (Rutile)

Solid State Communications, 1967
Abstract We have calculated the cohesive energy of TiO 2 using the Born-Mayer model. The result is U = −2742.2 kcal/mole which may be compared to the experimental value of U = −2873±30 kcal/mole. This result indicates that the bonding in rutile is predominantly ionic, although some covalent contribution is present.
