Juan Vivero-Escoto Receives Ralph E. Powe Junior Faculty Award from ORAU

vivero1Chemistry Assistant Professor Juan Vivero-Escoto has received the 2013 Ralph E. Powe Junior Faculty Enhancement Award from Oak Ridge Associate Universities (ORAU), a 109-member university consortium affiliated with Oak Ridge National Laboratory (ORNL). Dr. Vivero-Escoto was among 30 winners in a pool of 147 applicants from the university consortium. Only two faculty members per institution were permitted to apply. Applicants underwent a highly competitive peer-review process organized by ORAU among its members. Dr. Vivero-Escoto’s research interests include the design and synthesis of novel hybrid inorganic-organic materials for biomedical applications. This...

Lets congratulate Princess Mycia Cox, fellow nanoscale PhD student, for defending her Ph.D. dissertation, entitled: "Design and fabrication of low loss and low index optical metamaterials" last week. She completed the work under the supervision of Dr. Michael Fiddy (Electrical and Computer Engineering).



Mycia 22"Meta-materials" is an highly active area of research at UNC Charlotte. The researchers are specially interested in making materials which have their index of refraction close to zero or negative. Mycia's talk  was focused on making and studying these type of low index and preferably low loss materials -particularly at optical frequencies. Its also important that we make these materials through low cost processes   in order to make them in large enough quantities. Given these considerations, nanomaterials especially metallic or semiconductor nanocrystals fit the criteria .In mycia's case ,she fabricated and studied aluminium doped zinc-oxide nanoparticles. Her work was also supplemented by extensive simulations  and modeling. A large number of students including fellow nano students and...

Metal organic frameworks (MOFs) have emerged as an important class of porous materials noted for extremely high surface areas, functionalizable building blocks, and ease of synthesis. To date, a plethora of MOFs have now been synthesized and their physical properties examined with a focus on gas storage and separation. The catalytic diversity of MOFs, on the other hand, is emerging as an important area of MOF functionality with photo-catalysis a primary target of investigation. Two general strategies have been employed in the development of MOFs as photo-catalysts. The first utilizes the metal cluster building blocks and/or the ligands composing the framework as the photo-active component of the MOF. These photo-active framework MOFs typically contain lanthanide metal clusters or porphyrin based organic linkers which are both photo-chemically active. Alternatively, recent advances have been made in the development of MOFs in which the ligands connecting the metal clusters are composed of either free base or metallo-porphyrins. The advantages of this type of MOF photo-catalyst include a high density of available catalytic sites, ease of access of photochemical reactants and the ability to tune the framework to be selective...
