We construct chiral plasmonic molecules by assembling two individual chiral centers. Interestingly, depending on the exact arrangement of the centers, all combinations result in a chiral compound with a strong chiral optical response. Furthermore, we demonstrate that the overall circular dichrosim (CD) is determined by the response of the individual ...

Material surface engineering has attracted great interest in important applications, including electronics, biomedicine, and membranes. More recently, dopamine has been widely exploited in solution-based chemistry to direct facile surface modification. However, unsolved questions remain about the chemical identity of final products, their deposition kinetics and binding mechanism. In particular, the ...

Structural dynamics involving tight Au-Au bond formation of excited-state oligomers [Au(CN)(2)(-)](n) was studied using picosecond/femtosecond time-resolved emission and absorption spectroscopy. With selective excitation of the trimer ([Au(CN)(2)(-)](3)) in aqueous solutions, transient absorption due to the excited-state trimer was observed around 600 nm. This transient exhibited a significant intensity increase (τ ...

The mechanism and origins of selectivities in [Ni(NHC)]-catalyzed intramolecular (5+2) cycloadditions and homo-ene reactions of vinylcyclopropanes (VCPs) and alkynes have been studied using density functional theory. The preferred mechanism involves oxidative alkyne-alkene cyclization to form a metallacyclopentene intermediate, in contrast to cyclopropane cleavage pathway in the reaction with Rh(I) catalysts. ...

The degree of filling of titania nanostructures with a solid hole-conducting material is important for the performance of solid-state dye-sensitized solar cells (ssDSSCs). Different ways to infiltrate the hole-conducting polymer poly(3-hexylthiophene) (P3HT) into titania structures, both, granular structures as they are already applied commercially, and tailored sponge nanostructures, are investigated. ...

For self-assembled nanocrystals in 3D superlattices, called supracrystals, the crystalline structure of the metal nanocrystals (either single domain or polycrystallines) or nanocrystallinity, is likely to induce significant changes in the physical properties. Previous studies demonstrated that spontaneous nanocrystallinity segregation takes place in colloidal solution upon self-assembling of 5 nm dodecanethiol-passivated ...

Density functional theory computations of the Cu-catalyzed ring expansion of vinyloxiranes is mediated by a traceless dual Cu(I)-catalyst mechanism. Overall, the reaction involves a monomeric Cu(I)-catalyst, but a single key step, the Cu migration, requires two Cu(I)-catalysts for the transformation. This dual-Cu step is found to be a true two ...

Purpose: Shock wave lithotripsy (SWL) is a widely utilized treatment for renal and ureteral stones due to its noninvasive approach. Although minor complications arise in most patients, a relatively severe complication, perirenal or subcapsular hematoma, may also occur. We evaluate the possible risk factors for perirenal hematoma following SWL. Material ...

Three-coordinate complexes (bromo)[4-(2,2-dimethyl-1,3-dioxolan-4-yl)-phenyl](tri-tert-butyl-phosphine)palladium (1) and (bromo){4-[(tetrahydro-2H-pyran-2-yloxy)methyl]phenyl}(tri-tert-butyl-phosphine)palladium (2) were used to initiate Suzuki-Miyaura chain growth polymerization of 7'-bromo-9',9'-dioctyl-fluoren-2'-yl-4,4,5,5,-tetramethyl-[1,3,2]dioxaborolane (3). The polymerization was optionally terminated by end-capping with red-emitting N-(2-ethylhexyl)-1,6-bis(4-tert-octylphenoxy)-9-(4,4,5,5,-tetramethyl-[1,3,2]dioxaborolan-2-yl)-perylene-3,4-dicarboximide.

In Southwestern USA, the jimsonweed Datura wrightii and the nocturnal sphinx moth Manduca sexta form a pollinator-plant and herbivore-plant association. While certain plant volatile organic compounds (VOCs) attract moths for oviposition, it is likely that other host-derived olfactory cues, such as herbivore-induced VOCs, repel moths for oviposition. Here, we studied ...
