Baoshan Xing's Abstract: Engineered nanomaterials (ENMs) (in a size range of 1-100 nm) are found in an increasing number of the consumer and food products (e.g., lotions, socks, chewing gums), and are being used in many biomedical and environmental applications due to the rapid development and use of nanotechnology. Because of their high-volume production and widespread use, these engineered nanomaterials (ENMs) are being released into the environment. In this seminar, Dr. Xing will discuss the uptake of ENMs by plants, nanotoxicity to various organisms and the environmental processes involved in dispersion and transformation.


John Pojman's Abstract: Materials used for paintings have had a slow evolution.  Before the Renaissance, egg whites and other animal products were used for hold pigments to the surface.  The Masters used linseed oil-based paints.  No new medium was developed until the advent of acrylic pains in the 1950s.  Modified natural polymers, such as nitrocellose, allowed the development of durable cylinders for the Ediphone while 79 rpm records will still made from shellac until the 1950s.  We will explore these developments and a new medium developed by the speaker, “QuickCure Clay”, which doesn’t dry out and won’t harden until heated on the surface with a heat gun.


Michael Fayer's Abstract: Room temperature ionic liquids (RTILs) have properties that are distinct from other ionic liquids and from common organic liquids.  RTILs are liquid around room temperature in contrast to, e.g., liquid NaCl, which melts at 1074 K.  The low melting point of RTILs is typically achieved by using molecular ions, often organic, that are asymmetric, large, have diffuse or delocalized charge, or some combination of these properties.  The presence of these properties in the cation, anion, or both, prevents crystallization by reducing the enthalpic incentive and/or increasing the entropic cost.  The large number of cation and anion combinations result in a vast number of liquids with distinct properties.  The wide range of properties makes them useful in, or being considered for, a variety of applications.  Ultrafast two dimensional infrared (2D IR) and IR polarization selective pump-probe (PSPP) experiments were used to investigate the dynamics of the room temperature ionic liquids CnmimNTf2 (1-alkyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide).  The alkyl chains are ethyl, butyl, hexyl, and decyl.  Several IR vibrational probes were used to study the RTILs, particularly SeCN‒, BmimSeCN+, and CO2.  The 2D IR and PSPP experiments provide a wealth of information on the time scales and nature of the RTILs’ dynamical structures.  It is shown that electric fields in the liquids are an important source of the intermolecular interactions of the vibrational probe solutes with the RTILs.  RTILs are being developed for CO2 capture.  Experiments in bulk EmimNTf2 are compared to experiments in Supported Ionic Liquid Membranes, that is, porous polymer films, which will be important in CO2 capture applications.  Substantial differences in dynamics are observed in spite of the large pore sizes in the membranes.
