We decided to synthesize a series of new optically active
Pis bearing benzimidazole pendant groups from an equimolar mixture of dianhydride monomer compound (11) and different diamine derived from amino acids, including isoleucine (lie), valine (Val), methionine (Met), phenylalanine (Phe) (Sch.
Using DNA as a key tool, the interdisciplinary team took gold nanoparticles of different sizes and shapes and arranged them in two and three dimensions to form optically active
Chemical method produces racemic mixture of both D(-) and L(+) forms of lactic acid while fermentation method only produces optically active
L(+) form of lactic acid, which is required for PLA production.
These unique properties provide the potential of designing novel optically active
reagents for simultaneous molecular imaging and photothermal cancer therapy...." (1)
REMcodes are combinations of striped microparticles made of a tough, optically active
polymer/ rare-earth-doped nanocrystal composite that resists sunlight, heat, solvents and other extreme industrial conditions.
Prior to VISX, Dr Holliday has worked primarily in academia as well as spent three years at the Swiss Federal Institute of Technology, where he was involved with the utilization of optically active
polymers and crystals, to develop materials and techniques for very high density, holographic optical storage and computational systems.
Since the helical shape itself is chiral, if we can synthesize a polymer with a stable one-handed helical structure from an optically inactive achiral monomer, the polymer must be optically active
. This type of polymerization has been called the helix-sense-selective polymerization.
Our calculations show that the surface defects introduce mid-gap states that are weakly optically active
resulting in a lowest energy red shifted absorption band.
 succeeded in the first total synthesis of optically active
my-inositol trisphosphate involving 13 stepsi from readily available myo-inositol [28,29].
At the end of December the US Bureau of Engraving cancelled its Request for Proposals (RFP) for an optically active
windowed security thread for the new $100, dashing industry hopes that the new design for the country's flagship denomination would feature a holographic device, as reported in HN January 2005 the January 2005 issue of Holography News[R].
The Ceramospher HPLC column features optical-resolution packing material with high selectivity created from a spherical clay mineral carrying an optically active
Barghoorn, Schopf and Meinschein found porphyrins related to chlorophyll and hemoglobin, microfossils and optically active
hydrocarbons in shale from the Nonesuch formation....
