The research problem presented herein involved the
structural determination of several a,~-unsaturated acids
and esters. The solution to this problem was sought in the
nuclear magnetic resonance (n.m.r.) spectra of these compounds.
The n.m.r....
No current microfabrication technique exists for producing room-temperature, high-precision, point-to-point polymer nanofibers in three dimensions. Producing rounded structures in a third dimension is particularly difficult to accomplish with...
Chapter I . Seven novel head-to-tail cyclic pentapeptides and pseudopentapeptides containing the arginine-glycine-aspartic acid (RGD) tripeptide motif were synthesized. All of the peptides were constructed using solid phase peptide synthesis....
The acetogenin annonacin, from the tropical annonaceous plant Annona muricata, is a lipophilic, mitochondrial complex I inhibitor reported to be more toxic than rotenone to mesencephalic neurons. The temperate annonaceous plant Asimina tri/oba...
G-quadruplexes are thought to have biological importance, with studies based on small molecule interactions and quadruplex-interactive antibodies demonstrating their potential for formation in vivo. One potential biological function of quadruplex...
Varnish and its use has been known since ancient times. Altho the knowledge of varnish has been attributed to the Japanese as early as 500-600 B.C., Tschirsch and A.D. Stevens say that the Japs did not possess this art originally, but that they...
Contamination can be very difficult to remove from water. Once this water seeps into the ground, the difficulty grows exponentially. The Paducah Gaseous Diffusion Plant, located in Paducah, Kentucky, has contaminated the groundwater. The...
