Jacob Israelachvili print that page

be used to characterize the nature of intermolecular potentials and other molecular properties. Israelachvili is also well-known as the author of the textbook "Intermolecular and Surface Forces," published by Academic Press . This authoritative book describes the fundamental concepts and

Adhesion print that page

Spider_web_Luc_Viatour

Adhesion is the tendency of dissimilar particles and/or surfaces to cling to one another (cohesion refers to the tendency of similar or identical particles/surfaces to cling to one another). The forces that cause adhesion and cohesion can be divided into several types. The intermolecular forces

Force field (chemistry) print that page

In the context of molecular modeling , a force field refers to the form and parameters of mathematical functions used to describe the potential energy of a system of particles (typically molecules and atoms ). Force field functions and parameter sets are derived from both experimental

Soft matter print that page

Interesting behaviors arise from soft matter in ways that cannot be predicted, or are difficult to predict, directly from its atomic or molecular consituents. This is often because soft matter self-organizes into mesoscopic physical structures that are much larger than the microscopic scale

Lipid raft print that page

Space-Filling_Model_Sphingomyelin_and_Cholesterol

The plasma membrane of cells is made of a combination of glycosphingolipids and protein receptors organized in glycolipoprotein microdomains termed lipid rafts . [ 1 ] [ 2 ] [ 3 ] These specialized membrane microdomains compartmentalize cellular processes by serving as organizing centers

Van der Waals force print that page

Gecko_Leaftail_1

In physical chemistry , the van der Waals force (or van der Waals interaction ), named after Dutch scientist Johannes Diderik van der Waals , is the sum of the attractive or repulsive forces between molecules (or between parts of the same molecule) other than those due to covalent bonds

Surface forces apparatus print that page

The surface force apparatus ( SFA ) is a scientific instrument and technique pioneered by D. Tabor, R.H.S. Winterton, J.N. Israelachvili in the early 1970s at Cambridge University . By the mid-70's Israelachvili had adapted the original design to operate in liquids, notably aqueous solutions

Lipid bilayer characterization print that page

Sedimented_red_blood_cells

This potential complication has been given an argument against the use of one of fluorescence recovery after photobleaching (FRAP) to determine bilayer diffusion coefficients. In a typical FRAP experiment a small (~30 µm diameter) area is photobleached by exposure to an intense light source

Interbilayer forces in membrane fusion print that page

Fusion

Two hydrated bilayers experience strong repulsion as they approach each other. These forces have been measured using the Surface forces apparatus (S.F.A), an instrument used for measuring forces between surfaces. This repulsion was first proposed by Langmuir and was thought to arise due to
