We work on an fabrication method for “artificial” photonic quasi-crystal. The fabricated Penrose-type photonic quasicrystal shows ten-fold rotational symmetry. The Laue diffraction pattern from the photonic quasi-crystal is observed to be similar to that of the traditional alloy quasi-crys
Superhydrophobicity is a very important property of a solid surface and can be used in many applications such as self cleaning windows, icephobic surfaces (to avoid ice deposition on airplanes), self cleaning textiles and paints to mention some.
The major drawback of solar cell technology is the low efficiency. Introducing PhCBR would allow for higher efficiencies that improve over current metal back reflectors. The better the reflective properties for the designed back reflectors allow for light to be trapped within the solar ce
Nanometer-sized RuO2 materials with controlled shapes and dimensions have been synthesized by low-pressure chemical vapor deposition system. Transition metal oxides such as ruthenium oxide can be used as electrodes for lithium-ion batteries.
A series of presentations on light-matter interactions have been given at the West Las Vegas Middle School. These have served to promote connections between local schools and PREM program. Three NMHU PREM students organized four different science presentations, each approximately one hour
Planar electron-accepting π-systems are useful building blocks for both nonlinear optical and organic electronic applications. We have recently developed a convenient synthesis of dibromo bithiophenes and bithiazoles of type I (see below) that relies upon the base-catalyzed “Halogen dance”
Carbon-rich compounds and materials have garnered much attention recently due to their small band gaps and thus applications as organic conductors and ferromagnets that form monolayers in solid-phase state. One such type of materials that can form carbon monolayers are [N]phenylenes, hydro
Beta-peptides have been designed to mimic natural host-defense peptides. Unfortunately, very little is known about the molecular mechanism of action of these materials. During the past year Dr. Ortiz-Bermúdez and her research group have been conducting experiments in collaboration with Dr
On April 29, 2011 Wi(PR)2EM and the Science on Wheels Educational Center (SONW) organized and coordinated the First Arts, Sciences and Engineering Festival of UPRM (FACI-RUM, was its acronym in Spanish) at the Rafael A. Mangual coliseum at UPRM. This large event combined our NanoDays activ
Objective of this work was to test the thermal and mechanical properties of POSS coated SiC particles infused in epoxy polymers to produce nanocomposite. A non-contact and sonochemical method was developed to coat POSS on SiC nanoparticles and uniformly disperse in a polymer. These epoxy b
Objective of this study is to study the influence of functionalization of MWCNTs on the performance of nanocomposites. Approach: In this work, thermoset polymers were modified with pristine and amine functionalized MWCNTs. Thermomechanical thermal, rheological, and mechanical charact
Tuskegee University Center for Advanced Materials (T-CAM) hosted high school students during the summer of 2010 in an effort to expose the students to research and concepts pertaining to science, engineering, and technology. Research Experience for High School Students (REH) program occurr
