efforts on polymer adhesion with a special focus on adhesion mechanisms. It starts with an introduction to adhesion with explanatory notes on adhesion phenomena. Recent research on the adhesion mechanisms of mechanical coupling, chemical bonding and thermodynamic adhesion is then discussed. The area of adhesion promoters is reviewed with the focus on plasma and chemical treatments, along with direct methods for adhesion measurement. The topics of polymer blends and reactive polymerization are considered

kinetic mechanical energy which pushes the pistons of an engine. The energy transformation of life are subject to two laws of thermodynamics Thermodynamics = Study of energy transformations. First Law of Thermodynamics = Energy can be transferred and transformed, but it cannot be created or destroyed (energy of the universe is constant). Second Law of Thermodynamics = Every energy transfer or transformation makes the universe more disordered (every process increases the entropy of the universe)

Meyer et al. C.R. Chimie 10 2007) 929-947. - 1) Pourquoi étudier la complexation du plutonium par l’EDTA ? (p 930) Les phénomènes de complexation mettant en jeu le ligand EDTA sont très connus. Néanmoins, très peu d’études thermodynamiques traitant de la complexation entre l’EDTA et le plutonium

the product of the square root of the flaw length (a) and the stress at fracture (σ_f) was nearly constant. Figure 3: Edge crack of length a The previous statement has no meanings in the linear elastic theory and then Griffith developed a thermodynamic model to explain it. He first considered the expansion of the flaw required the creation of two new surfaces and then an increase of the surface energy〖 γ〗_S. Secondly, he considered that the opposite effort to the propagation of the crack was

HYDRATED. Without sweat as a cue during cold-weather activities, you can easily dehydrate. If your body misinterprets your thirst as hunger, that Gruyere fondue will own you. Carry a water bottle and sip generously. STEP 2: WARM UP. Eating has a thermodynamic (heat-generating) effect, explains nutritionist Heidi Skolnik. So we often reach for food not necessarily because we're hungry, but because we're cold. After a wintry outdoor activity, bypass the kitchen and toss a log onto the fire or snuggle
