Structures and Properties of Solids - Uni Siegen

2.1 Basics of Structures Trends of the atomic / ionic radii • Increase on going down a group (additional electrons in different shells) • Decrease across a period (additional electrons in the same shell) • Ionic radii increase with increasing CN (the higher its CN, the bigger the ions seems to be, due to increasing d!!!) • Ionic radius of a given atom decreases with increasing charge

Adsorption Basics: Part 1 - AIChE

(not covalent bonding). Bonding energies in adsorption range from about 10 to 70 kJ/mol, much lower than typical covalent bond energies of 200 to 500 kJ/mol. The adsorp-tion bonding energy is high enough for adsorption to occur, yet low enough to allow the adsorbent to be regenerated by removing the adsorbed molecules. Equilibrium considerations

A Silane Primer: Chemistry and Applications of Alkoxy Silanes

the substrate interface and improve bonding is well known. In addition, silanes have been added to latices and hydrolyzed to form an interpenetrating polymer network (IPN) polymer with improved properties.1 Two types of alkoxy silanes have widespread application in the coatings industries: alkyl/aryl and organofunctional.
