We have developed new state of the art density matrix renormalization group (DMRG) and transport codes, which can deal with large electron systems with interaction. Right two figures represent some results we obtained with our collaborators. On the right side, top panel shows our quantum
In 2011, Gallaudet University joined the Howard, Hopkins Prince Georges Community College PREM. Three Gallaudet students were mentored by Prof. Paul Sabila in summer research at Howard in Jason Matthews’ research group. In addition to research, the students took part in nanotechnology trai
We have developed SERS based sensor for extremely toxic cyanide ion recognition quickly, selectively and accurately without any tagging, at 110 ppt level. Download this highlight
JSU-PREM Participants presented Nanoscience exhibition at the Memphis Zoo, Memphis, TN. Over 300 Participants gathered at the Zoo for Nano Day Download this highlight
Students in Bridge Program along with Dr. Ann Watts, Associate Vice President for Academic Affairs. A Pre-Freshman Bridge Summer Science Program at Morehouse College was designed to develop an advanced level of scientific literacy among pre-freshmen science majors with the goal of incr
Clark Atlanta University and Georgia Tech. researchers supported by the NSF PREM project studied the electronic characteristics of multilayer epitaxial graphene under a perpendicularly applied electric bias.
Clark Atlanta University researchers supported by the NSF PREM project worked on supramolecular self-assembly of biofunctional-modified poly(2 methoxystyrene) on graphene nanoribbons. The bioactive polymer has attracted a considerable interest owing to its versatile properties as a bisosen
Bio-conjugated Popcorn shape gold nanoparticle can pick multiple drug resistantSalmonella DT104 bacteria from food sample. A simple colorimetric test can detect Salmonella DT104 in 10 colony-forming unit (CFU)/mL level with high selectivity over other pathogens.
Advanced energy absorption systems have recently been developed, in which external work is converted into stored energy by infiltrating nanoporous materials with liquid phases. Three-dimensionally ordered mesoporous (3DOm) carbon is studied as a new nanoporous material matrix for energy s
Self-assembled block copolymers (see the upper inset) can accommodate nanofillers in given polymeric domains resulting in an ordered spatial distribution of nanoparticles, induced by the self assembly of block copolymers and the preferential trapping on the nanofiller (see the left figure
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.
