Luis González-Urbina received his B.S. in Chemistry and a M.S. in Physical Chemistry from the University of the Basque Country (UPV-EHU), Spain, and a M.S. in Material Engineering for Microelectronics from the University of Leuven (KU Leuven), Belgium. After a short time in industry he obtained a Ph.D. in Chemistry working at the group of Photonic Crystals of Prof. Clays. He has done research on Carbon Nanotube fabrication with the group of Prof. Seo (KU Leuven) and on electrochemical CO2 sequestration at George Washington University.
Professor González-Urbina has taught at Hostos Community College and Guttman Community College before joining Borough of Manhattan Community College in 2016.

Courses Taught
- This is a survey course that introduces essential topics in atomic and molecular structure, chemical and physical properties, and chemical reactivity. These concepts will form a basis for understanding biological applications and environmental issues.
Corequisite: CHE 109
Course Syllabus - This course investigates chemical concepts through laboratory experiments on structure, chemical reactions, and energy changes. Experiments will that relate to biological chemistry and environmental measurements will also be included. Concepts relevant to the laboratory experiments will be discussed.
Corequisite: CHE 108
Course Syllabus - This course is designed specifically for the non-science major. It explores the world of atoms and molecules and relates this submicroscope world to the daily life of the student. Topics to be discussed include plastics, foods, the environment, genetics, and drugs.
Course Syllabus - This is a one-semester course designed especially to meet the needs of students in the Health Technology Programs. Topics include modern atomic theory and an introduction to the molecular basis of matter through the study of chemical principles and reactions. Lecture and laboratory are integrally related.

Energy transfer in Colloidal Photonic Crystals
From ancient times human beings have been fascinated by the remarkable optical properties of colloidal crystals. The mystical opals and insects displaying iridescent colors incomprehensible for our ancestors have turned into the models for the study of photonic crystals. Photonic crystals are structures with dimensions in the order of the nanometers, thousand times smaller than the thickness of a human hair. The scrupulous arrangement of the structure, repeated over the space, generates a medium that is able to interact with the electromagnetic radiation, and which allows us to manipulate light.
The efficiency of organic light emitting devices (OLEDs) and of light harvesting devices like photovoltaics (OPVs) is hindered by the short life times of fluorescence excitons. Energy transfer mechanisms between different molecules have been proposed to improve the efficiency of these devices. In the past we demonstrated that photonic structures have the potential to improve energy transfer mechanism, or even to force forbidden intramolecular energy transfers. The photonic structures used on previous works were colloidal photonic crystals.
A colloid is a two-phase system, where one phase is dispersed in a second phase called the continuous medium. A colloidal crystal is formed from solid monodisperse beads of particles, ranging from a few nanometers to the micrometer scale. The monodispersity of the nanoparticles is a key factor, because the periodicity of the structure will rely directly on the monotonic size of the beads, and therefore, unintentional different sizes cannot result in a periodic structure. Colloidal photonic crystals are a simple and inexpensive platform to study the behavior or light emitters in confined media, and a complex sandwich-like structure.
In the present proposal a simple configuration pursues to improve the previous results and to extend the study to a larger range of molecules. The organometallic molecules to be studied will be chosen among those typically used in commercial devices seeking a larger interest from the community. The project will involve the synthesis of the colloidal nanoparticles, functionalization and deposition into photonic crystals, and characterization.
