Drug Delivery Experiments
0.0 out of 5 stars
17 Oct 2012 | Downloads
Attached are five files detailing four separate experiments that are designed to be used in an undergraduate curriculum. The alginate bead experiment utilizes an alginate hydrogel drug delivery system to affect the rate at which a dye or protein is released. The lozenge experiment is a drug...
Discussion on Hamaker Constant
03 May 2024 | Publications
The Hamaker constant is a force constant used for describing the van der Waals (vdW) force. The magnitude of the Hamaker constant reflects the strength of the vdW force between two particles, or between a particle and a substrate. It depends on the material properties of both the interacting...

Particle and Thin Film Adhesion
03 May 2024 | Series
The adhesion of micron and sub-micron scale particles to surfaces is of tremendous interest in a wide range of industrial and civilian applications. We measure directly the adhesion of particles to surfaces using atomic force microscopy and develop experimentally-validated, science-based models...
Hamaker Constants in Integrated Circuit Metallization
A new method for determining Hamaker constants was examinedfor materials of interest in integrated circuit manufacture. Anultra-high vacuum atomic force microscope and an atomic force microscopeoperated in a nitrogen environment were used to measurethe interaction forces between metals,...
A Theoretical and Experimental Study of Surface Forces in Adhesion of Particles to Thin Films
The interactions between micron- and nano-particles and rough surfaces are of great importance and have numerous applications in surface science and biotechnology. It is essential to have estimates of surface/intermolecular forces between interacting bodies to describe and to manipulate the...
