Total Synthesis of (±)-Cis-Trikentrin B via Intermolecular 6,7-Indole Aryne Cycloaddition and Stille Cross-Coupling
(Elsevier, 2014-09-30)An efficient total synthesis of the annulated indole natural product (±)-cis-trikentrin B was accomplished by means of a regioselectively generated 6,7-indole aryne cycloaddition via selective metal-halogen exchange from ... -
Rational design of cyclopropane-based chiral PHOX ligands for intermolecular asymmetric Heck reaction
(Beilstein-Institut, 2014-07-07)A novel class of chiral phosphanyl-oxazoline (PHOX) ligands with a conformationally rigid cyclopropyl backbone was synthesized and tested in the intermolecular asymmetric Heck reaction. Mechanistic modelling and crystallographic ... -
Charge-Transfer Induced Magnetic Field Effects of Nano-Carbon Heterojunctions
(Nature Publishing Group, 2014-08-22)Room temperature magnetic field effects have not been definitively observed in either single-walled carbon nanotubes (SWCNTs) or C60 under a small magnetic field due to their weak hyperfine interaction and slight difference ... -
Lifting the Mask: Identification of New Small Molecule Inhibitors of Uropathogenic Escherichia coli Group 2 Capsule Biogenesis
(Public Library of Science, 2014-07-01)Uropathogenic Escherichia coli (UPEC) is the leading cause of community-acquired urinary tract infections (UTIs), with over 100 million UTIs occurring annually throughout the world. Increasing antimicrobial resistance among ... -
Discovery of a Novel Compound with Anti-Venezuelan Equine Encephalitis Virus Activity That Targets the Nonstructural Protein 2
(Public Library of Science, 2014-06-26)Abstract Alphaviruses present serious health threats as emerging and re-emerging viruses. Venezuelan equine encephalitis virus (VEEV), a New World alphavirus, can cause encephalitis in humans and horses, but there are no ... -

Photoacoustic contrast imaging of biological tissues with nanodiamonds fabricated for high near-infrared absorbance
(Society of Photo-optical Instrumentation Engineers, 2013-02)Radiation-damaged nanodiamonds (DNDs) are potentially ideal optical contrast agents for photoacoustic (PA) imaging in biological tissues due to their low toxicity and high optical absorbance. PA imaging contrast agents ... -
The renaissance of hybrid solar cells: progresses, challenges, and perspectives
(Royal Society of Chemistry, 2013-06-12)Solution-processed hybrid solar cells, a blend of conjugated polymers and semiconducting nanocrystals, are a promising candidate for next-generation energy-conversion devices. The renaissance of this field in recent years ... -

Solid-Liquid Interfacial Premelting
(American Physical Society, 2013-02-28)We report the observation of a premelting transition at chemically sharp solid-liquid interfaces using molecular-dynamics simulations. The transition is observed in the solid-Al—liquid-Pb system and involves the formation ... -
Calculation of the interfacial free energy of a binary hard-sphere fluid at a planar hard wall
(American Institute of Physics, 2014-01-08)Using molecular-dynamics simulation and Gibbs-Cahn Integration, we calculate the interfacial free energy γ of a binary hard-sphere fluid mixture at a structureless, planar hard wall. The calculation is performed as a ... -
Single-fiber-laser-based wavelength tunable excitation for coherent Raman spectroscopy
(Optical Society of America, 2013-06)We demonstrate coherent Raman spectroscopy (CRS) using a tunable excitation source based on a single femtosecond fiber laser. The frequency difference between the pump and the Stokes pulses was generated by soliton self-frequency ... -
Optimally shaped narrowband pulses for femtosecond stimulated Raman spectroscopy in the range 330-750 nm
(Optical Society of America, 2013-03-25)Spectral compression of femtosecond pulses by second harmonic generation in the presence of substantial group velocity dispersion provides a convenient source of narrowband Raman pump pulses for femtosecond stimulated Raman ... -
The role of retinoic acid in hepatic lipid homeostasis defined by genomic binding and transcriptome profiling
(BioMed Central, 2013-08-28)Background: The eyes and skin are obvious retinoid target organs. Vitamin A deficiency causes night blindness and retinoids are widely used to treat acne and psoriasis. However, more than 90% of total body retinol is ... -
Palladium-catalyzed substitution of (coumarinyl)methyl acetates with C-, N-, and S-nucleophiles
(Beilstein-Institut, 2012-07-27)The palladium-catalyzed nucleophilic substitution of (coumarinyl)methyl acetates is described. The reaction proceeds though a palladium π-benzyl-like complex and allows for many different types of C-, N-, and S-nucleophiles ... -
