Direct measurement of polariton–polariton interaction strength

[Direct measurement of bone mechanical strength].

Osmocapsules for direct measurement of osmotic strength.

Monodisperse microcapsules with ultra-thin membranes are microfluidically designed to be highly sensitive to osmotic pressure, thereby providing a tool for the direct measurement of the osmotic strength. To make such osmocapsules, water-in-oil-in-water double-emulsion drops with ultra-thin shells are prepared as templates through emulsification of core-sheath biphasic flow in a capillary microf...

Direct measurement of a tethered ligand-receptor interaction potential.

Many biological recognition interactions involve ligands and receptors that are tethered rather than rigidly bound on a cell surface. A surface forces apparatus was used to directly measure the force-distance interaction between a polymer-tethered ligand and its receptor. At separations near the fully extended tether length, the ligands rapidly lock onto their binding sites, pulling the ligand ...

Direct measurement of interaction forces between charged multilamellar vesicles†.

Depletion-attraction induced adhesion of two giant (∼ 40 μm), charged multilamellar vesicles is studied using a new Cantilevered-Capillary Force Apparatus, developed in this laboratory. The specific goal of this work is to investigate the role of dynamics in the adhesion and de-adhesion processes when the vesicles come together or are pulled apart at a constant velocity. Hydrodynamic effects ar...

Measurement of communal strength

Communal strength refers to a person’s degree of motivation to respond to a communal partner’s needs. The development and testing of a questionnaire measure of communal strength is described. Study 1 involved item selection. Studies 2 and 3 found that the 10-item communal strength measure taps a construct distinct from behavioral interdependence as measured by the Relationship Closeness Invento...
