The spatial distribution of the terminal groups of poly(amido amine) dendrimers have been determined experimentally by small-angle neutron scattering with deuterium labeling and scattering contrast variation. The radius of gyration of deuterated term

Vitamin A and its derivatives (commonly termed retinoids) are widely used in topical anti-aging products. Certain retinoids such as retinol and its esters are available without a prescription, while others such as tretinoin are available only via pre

The accelerated synthesis of regular dendritic poly (ether-urethane) macromolecules through growth of two generations in a single synthetic operation has been explored. This procedure requires the use of two AB2 monomers such as 3,5-diisocyanatobenzy
