Dr. Couzis and Dr. Maldarelli have experience in developing easily scalable molecular engineering methods for fabricating nanoscale patterns of chemical functionality on solid surfaces. These patterns are then used to develop templates for the growth of materials, or they are used as building blocks for the fabrication of arrayed biosensors.
Dr. Delale has experience in failure phenomena associated with non-homogeneous materials, interfaces, adhesive bonding and delamination. He is a Full Professor and Chair of Mechanical Engineering at CCNY. His most recent research activities are in both experimental and theoretical studies of damage behavior of polymer as well as ceramic matrix composites (including nanocomposites). He has served on the editorial board of Composites Engineering and is the author of more than 70 refereed publications.
Dr. Dorsinville is working in the area of nonlinear optical properties of SC quantum dot composites, single-wall CNTs, and photonics. Dr. Dorsinville has a vast experience in the characterization of optoelectronic materials and devices based on organic materials. He has more than 100 publications and 2 patents related to the nonlinear optical characterization, fast photoconductivity and electroluminescence of organic and hybrid semiconductor-organic materials. Dr. Dorsinville is currently chair of the EE Department at CCNY.
Dr. John has experience in biobased organic synthesis for novel amphiphiles as building blocks in supramolecular chemistry. He is working on different aspects of supramolecular chemistry, green chemistry and soft materials, to generate nanoscale architectures and materials such as liquid crystals, gels, helical fibers and tubes. This study at the molecular level facilitates the new developments in science and technology via nanotechnology. In addition to this, currently he is developing lipidnanoparticle conjugates in gel, fiber and new methods in amphiphile mediated nanoparticle synthesis.
Dr. Kretzschmar has experience in the assembly of nanomaterials and the modification of nanomaterial surfaces. She is an Associate Professor in the Chemical Engineering Department. Her current activities involve the directed assembly of particles and the fabrication of patchy particles. Patchy particles are particles with active anchor patches that enable their directed assembly. She has taught both the Nanomaterials Course and the Nanomaterials Laboratory to over 75 students.
Dr. J. Koplik has experience in elementary particle theory and fluid mechanics, focusing on (classical) disordered systems.He uses molecular dynamics simulations methods in a variety of problems, including determining boundary conditions, liquid drop spreading dynamics, phase separation, solidliquid interactions, coalescence, stress singularities, non-Newtonian rheology, gas dynamics, and surfactant dynamics, totalling more than 50 published papers in this area. The general theme in his work is to relate macroscopic behavior to atomic-scale dynamics, using numerical simulation of nanoscale phenomena. Also, he is the associate editor of Physics of Fluids and a fellow of the American Physical Society.
Dr. Lenzner has experience in a broad range of laser-matter interactions (time-resolved measurements, generation of short high voltage pulses in semiconductors, investigation of carrier diffusion processes). His experience in the construction of laser systems include oscillator, amplifier and subsequent pulse compression and the generating of ultrashort pulses with pulse durations down to a few femtoseconds. Further, he has applied these pulses to generate X-ray radiation in noble gas plasmas and to investigate laser-induced breakdown in gases as well as in solids. Of special research interest is the investigation of ultrafast processes in laser-solid interaction as well as development and application of laser systems for refractive eye surgery.
Dr. Li has experience in nano/micromechanics, viscoelastic behavior of polymer-matrix composites, viscoplastic behavior of metal-matrix composites, electro-mechanical coupling behavior of ferroelectrics and their composites. She has already developed two graduate courses on “Nano/micromechanics” and “Physical Properties of Materials”. Her current research activities are on elastic properties of nanotubes and nanotube-reinforced composites, viscoplastic behavior of nano-crystalline materials, and electromechanical coupling of ferroelectrics.
Dr. Morris has experience in the simulation, rheometry and rheological modeling of colloidal
dispersions including gelling nanoparticulate systems; bulk flow modeling of these materials includes published work in microfluidic flows.He also has industrial experience in design of loading levels of cross-linking for aqueous polymeric solutions by metallic oxide (titanate and zirconate) nanoparticles.
Dr. Tu has experience in the design, synthesis and characterization of peptide-based self-assemblies, where nanoscale patterns can be tailored by functional variation in the sequence. His research objectives focus on the rational construction of interfacial peptide crystals. These peptide monolayers can then be applied to study a wide-range of phenomena at sub-micron length scales, including sequence specific DNA-binding, inorganic templated nanostrucutres, and interfacial folding.
Dr. Vazquez has experience in the manipulation of quantum dots for biological imaging. Her
laboratory is able to functionalize the nanoparticles and use them for both fixed and live cell imaging of cellular structures. Dr. Vazquez has developed two nanotechnology-based courses for biomedical engineering and mechanical engineering. In addition, she has developed an undergraduate course via the CUNY Honors College that underscores the societal impacts of nanotechnology and nanoscience innovations.
Dr. Yu has experience in the synthesis of semiconductor quantum dots and carbon nanotubes, and their optical characterization by single dot fluorescence and single nanotube Raman microscopy.40,41 In addition, he is also interested in single molecule spectroscopy of conjugated polymers,42 and application of single molecule spectroscopy to biophysical problems. His group has developed a novel beamscanning fluorescence and Raman imaging microscope, and is able to detect single quantum dots and carbon nanotubes for spectroscopic characterization.
