Acoustic-optical phonon up-conversion and hot-phonon bottleneck in lead-halide perovskites
A stronger phonon bottleneck effect in hybrid perovskites than in their inorganic counterparts is shown, which suggests a new and general method for achieving long-lived hot carriers in materials. Expand
Nanoprecipitation and Spectroscopic Characterization of Curcumin-Encapsulated Polyester Nanoparticles.
The overall outcome suggests that the polyester NPs prepared using the method reported herein are an attractive system for encapsulating and stabilizing curcumin in the aqueous environment. Expand
Cooperative binding and stabilization of the medicinal pigment curcumin by diamide linked γ-cyclodextrin dimers: a spectroscopic characterization.
The overall results indicate that the diamide linked γ-CD dimers are highly promising systems for curcumin delivery in vivo due to effectiveCurcumin stabilization. Expand
Ultrafast Carrier Dynamics in Methylammonium Lead Bromide Perovskite
The high open-circuit voltage of perovskite solar cell based on CH3NH3PbBr3 is suitable for a tandem system. It is important to understand the carrier dynamics to aid the optimization of solarExpand
Total synthesis of gelsemoxonine.
A one-pot isomerization reaction of the α,β-unsaturated aldehyde to the saturated ester via the TMSCN-DBU reagent combination allowed a facile diastereoselective introduction of the latent nitrogen functionality of the unique azetidine moiety. Expand
Imaging the motion of electrons across semiconductor heterojunctions.
By assembling images taken at different time-delays, a movie lasting a few trillionths of a second of the electron-transfer process in the photoexcited type-II heterostructure is produced-a fundamental phenomenon in semiconductor devices such as solar cells. Expand
Specific complexation of disaccharides with diphenyl-3,3′-diboronic acid that can be detected by circular dichroism
Abstract For the development of new receptor molecules that can recognize sugar molecules, we synthesized diphenyl-3,3′-diboronic acid (2). The distance between the two boronic acids in 2 is designedExpand
