This project focused on the growth of Cu2O
nanocubes in microwells from nanoparticle
“seeds.” The seeds were first formed by the
reduction of copper sulfate with ascorbic
acid in the presence of the surfactant
poly(ethylene glycol) (PEG). Upon reaction
within the microwell, the seed solution
formed a larger single crystal....
Every year millions of Americans go to the
emergency room with symptoms of a heart
attack. More than half a million Americans
die each year of myocardial infarctions (MI)
caused by coronary heart disease (CHD).
CHD detection is currently limited to EKG
analyses of electrical signals generated by
the heart...
Alzheimer’s disease (AD) is a progressive
mental disorder that affects 23 million people
worldwide. It is pathologically characterized
by amyloid plaques and tau tangles that
form in the brain. The hard, insoluble amyloid
plaques develop from the naturally
secreted amyloid beta peptide, which can
also assemble into toxic oligomeric forms...
While nanoscale device prototypes using
carbon nanotubes abound, no mass
production-scale technique exists for examining
properties of a batch of nanotubes.
Dielectrophoresis, on the other hand, has
received much attention in the press as a
method of separating and trapping particles.
In this research, a method of developing
mass production-scale...
Chemists and physicists have been interested
in the optical properties of metal nanoparticles
since the time of Michael Faraday.1
New approximation techniques for different
sizes and geometries have created renewed
interest in and investigation of these particles.
Many different arrays of particle extinctions
of various shapes and sizes have been...
The development and applications of
organic/DNA molecules for the use of DNA
detection systems are reported here. In particular,
two different hybrids are synthesized:
DNA/polymer hybrids and small-molecule
DNA hybrids. DNA/polymer hybrids are especially
useful considering that their functionality
may be varied according to the polymer
selected. The hybrids are...
Several phosphonate-functionalized molecular
squares have been successfully synthesized,
and the fabrication of multilayer films
on both conductive and semiconducting
platforms has been demonstrated. These
films were grown using the well-documented
zirconium phosphonate multilayer method.
The layer-by-layer growth rate is uniform.
Experiments suggest, however, that the
molecular squares adopt a semi-collapsed...
The recent military-style assault on the office of the French satirical magazine Charlie Hebdo , followed by a separate hostage standoff at a Kosher supermarket traumatized Paris and sent shock waves across Europe. The three-day terror spree in Paris ended with the deaths of 17 victims and three gunmen. The...
Innovative companies such as Uber and Airbnb have pioneered a new mode of business: the sharing economy. Uber, a car-sharing service, allows individual car owners to act as taxi drivers, connecting individuals seeking rides with those with cars willing to drive them, through a mobile app. Airbnb is a similar...
