Inorganic/Organic Hybrid Structures for Photovoltaics: Low cost roll to roll processing of solar cell

The preparation of competitive solar energy conversion technologies has been limited by the cost and efficiency of modern materials. We have been developing new approaches to layered inorganic/organic photovoltaic materials on flexible substrates. The flexible thin film solar cell is based on a combination of organic bulk heterojunction strategies with semi-conductor nanostructures. These hybrid inorganic/organic systems require development of new materials and processing technologies in order to make them suitable for low cost roll-to-roll manufacturing. Titanium dioxide nanoparticles, conducting polymer films such as polyethylenedioxythiophene (PEDOT) and polyaniline (PANI), and self-assembled layered materials of laponite have been prepared on polyethylene terephthalate (PET) substrates. We have also explored alternative transparent conducting electrode layers for flexible substrates including doped ZnO and CVD deposited conducting polymers. In this presentation, we will explore recent advances in the preparation, processing, and testing of these hybrid photovoltaic devices completed at the new Center for Autonomous Solar Power (CASP) and the Center for Advanced Microelectronics Manufacturing (CAMM) at Binghamton University’s Center of Excellence

Water Splitting Chemistry using Photocatalytic Semiconductors and Molecular Co-Catalysts

From the energy demands of the modern age and the need to preserve environmental quality, there is a current push towards finding renewable energy technology. Fuel cells are one such target because the energy source can be garnered from solar power and the naturally abundant water supply. Water oxidation and hydrogen production are fundamental steps in the so-called water splitting process. The availability of photo-generated excitons in semiconductor materials facilitates water oxidation and proton reduction through an unknown mechanism. Efficient photoanodes for water oxidation are crucial for any scheme to convert the energy in sunlight to fuels. We utilize computational methods, based on density functional theory, to obtain a fundamental, atomistic understanding of water oxidation mechanisms in photocatalytic semiconductors. To aid our understanding of hydrogen production and oxidation, we turn to hydrogenase enzymes which catalyze both processes efficiently. Aiming to design hydrogenase-like catalysts with equal efficiency, computational methods are applied to explore features of molecular catalysts and evaluate their contributions to overall catalytic ability.

Prof. Ronald Breslow, Columbia University

How did it all get started?

Work on artificial enzymes that perform the synthesis of amino acids from ketoacids led us to examine the properties of alpha-methyl amino acids. Recently these have been identified as components of carbonaceous chondritic meteorites such as the one that landed near Murchison Australia in the last century. These unusual amino acids arrive with excesses of stable chirality, all of the L configuration, and we will describe how they could have been formed. We showed that they can generate normal amino acids under credible prebiotic conditions, and with some chirality transfer. We also showed that the modest chirality that resulted could be amplified to high enantioexcesses of normal L aminoacids, using either thermodynamic or kinetic processes. We have shown that we can also amplify modest excesses of D nucleosides to high enantioexcesses by related processes. Finally, we have also shown the likely origin of D sugars. The resulting amino acids, sugars, and nucleosides can then be suitable materials for the creation of life.

From Molecules to Macromolecules to Materials: Controlling structure through synthesis

The control over structure facilitated by modern synthetic techniques enables control over the assembly of molecules and macromolecules in functional materials. We have designed and synthesized several classes of block and star-block copolymers with stimulus-responsive components. These polymers form assemblies with shapes and sizes that are dependent upon specific conditions. For example, we have investigated a range of synthetic systems that are designed to assemble in water into smaller micellar aggregates at low temperatures and larger vesicles at higher temperatures. The structural shifts in these systems under specific conditions will be discussed. A number of factors, including block size and extent of interblock interactions, appear to be important in controlling transformation rate. We will describe the design of these and other systems and our efforts to better understand the behavior of the resulting materials.

Surface Crystal Growth and Stabilization of Amorphous Pharmaceutical Solids

Glasses are amorphous materials that combine the mechanical stability of solids with the microscopic spatial uniformity of liquids, making them ideal for many applications, including electronics, bio-preservation and drug delivery. Amorphous solids, however, are inherently unstable, and can crystallize over time, sometimes surprisingly fast. Recent studies have discovered that as organic liquids are cooled to become glasses, crystal growth at the free surface can be substantially faster than in the interior. This phenomenon is uncommon for inorganic materials and it is generally terminated as the glasses are heated to become liquids. We have applied scanning electron microscopy (SEM) and real-time atomic force microscopy (AFM) to investigate the surface crystal growth on glassy indomethacin (IMC), an anti-inflammatory drug, in the alpha and gamma polymorphs. The high-resolution microscopies provided complete micro-structural details of surface crystal growth. We observed that surface crystals rise hundreds of nano-meters above the amorphous surface as they grow laterally, and are surrounded by depletion zones. Upon heating above the glass transition temperature, the onset of liquid flow embeds upward-growing surface crystals and terminates their growth, but this effect is remarkably mild for the gamma polymorph of IMC. This effect arises because the velocity of liquid flow exceeds the growth front velocity, causing the wetting and embedding of upward-growing surface crystals. These findings are important for understanding and predicting the stability of amorphous drugs.
During the seminar, we will discuss the educational pathways and the career opportunities provided by the B.S. degree program in Pharmaceutical Science at York College.

Holiday Party and 2015 Board Elections


Maria Mercurio-Zappala, Associate Director, New York City Poison Control Center

The Poison Center: Current Topics

The Poison Center is an emergency telephone hotline that is available to both the public and health care providers 24 hours a day, 7 days a week. the Poison Center is in a unique position to identify potential public health risks, new drugs of abuse trends, and potential bioterrorism activity. In this presentation, the speaker will discuss various topics from holiday toxins to “what’s new” in the news such as the opioid epidemic
