Drawable Carbon Nanotube Array for High-Performance Artificial Muscles and Energy Harvester

A drawable Carbon Nanotube (CNT) array is a special type of CNT forest, in which individual nanotubes are aligned and grown vertically on a substrate through a chemical vapor deposition (CVD) process. Most strikingly, a macroscopically aligned, pure, and pristine

Critical Micelle Concentrations (CMCs) - Avanti® Polar Lipids

The critical micelle concentration (CMC) can be approximately defined as the lipid monomer concentration at which appreciable amounts (>5% of total) of micellar aggregates first begin to appear in the equilibrium: nM1Mn

Serotonin Synthesis and Metabolism

Serotonin (5-hydroxytryptamine) is principally found stored in three main cell types - i) serotonergic neurons in the CNS and in the intestinal myenteric plexus, ii) enterochromaffin cells in the mucosa of the gastrointestinal tract, and iii) in blood platelets. Metabolism

Cholecystokinin and Gastrin Receptors

The naturally occurring peptides, cholecystokinin (CCK) and gastrin closely resemble each other at their carboxyl terminus, which is the biologically active portion of the molecules.
