We show that, when gold nanospheres are excited at the red side of the surface plasmon resonance (SPR) wavelength at 592 nm by a continuous wave (CW) laser, they give substantial up-converted luminescence in the SPR wavelength range. The luminescence intensity scales as a second-order function of the excitation power, with a quantum yield ~1/50 of(More)
As an emerging type of optically active materials, chiral molecules-stabilized semiconductor quantum dots (QDs) have achieved extensive attention. Unfortunately, understanding of the optical characteristics of chiral QDs observed by circular dichroism (CD) spectroscopy remains a great challenge due to their rather weak signals. Herein, we successfully(More)
To study slow mass transport in confined environments, we developed a three-dimensional (3D) single-particle localization technique to track their microscopic movements in cylindrical nanopores. Under two model conditions, particles are retained much longer inside the pores: (1) increased solvent viscosity, which slows down the particle throughout the whole(More)
Two tri(benzo[b]thiopheno)subporphyrazine regioisomers with C3 and C1 molecular symmetry have been isolated from the cyclotrimerization of benzo[b]thiophene-2,3-dicarbonitrile as the first five-membered-heterocycle-fused subphthalocyanine analogues. Optical resolution of both regioisomers was achieved by using a chiral HPLC technique, affording the first(More)
A C1-symmerical meso-substituted ABCD-type porphyrin, [5-phenyl-10-(2-hydroxynaphthyl)-15-(4-hydroxyphenyl)porphyrinato]zinc(II) (1), has been synthesized and characterized. The molecular structure of 1 has been determined by single-crystal X-ray diffraction analysis. The complex 1 crystallizes in a triclinic system with one pair of enantiomeric molecules(More)
Chiral binaphthyl-linked subphthalocyanines (SubPcs) (1) have been prepared by the cyclotrimerization reaction of a phthalonitrile linked with (R)- and (S)-2,2'-binaphthyl in the presence of BCl3, and characterized by various spectroscopies including NMR, electronic absorption, CD, and MCD, as well as electrochemistry.
The association of coal and oil shale had been a hot topic for a long time. Various types of association of coal and oil shale can be found in one basin, for instance, the coal can act as the roof or floor or interlayer of the oil shale, etc. The most crucial factor for the formation of oil shale is stratification and seasonal blooming of lower plankton,(More)
Next generation sequencing (NGS) has revolutionized life sciences research. However, GC bias and costly, time-intensive library preparation make NGS an ill fit for increasing sequencing demands in the clinic. A new class of third-generation sequencing platforms has arrived to meet this need, capable of directly measuring DNA and RNA sequences at the(More)
Endometriosis is a complex and enigmatic disease that arises from the interplay among multiple genetic and environmental factors. The defining feature of endometriosis is the deposition and growth of endometrial tissues at sites outside of the uterine cavity. Studies to date have established that endometriosis is heritable but have not addressed the causal(More)
A lot of efforts have been devoted to engineering the delivery of hydrophobic drugs due to the high demand of chemotherapy against cancer. While early developed liposomes and polymeric nanoparticles did not meet the requirements of high drug loading efficiency, pure drug nanoparticles appeared to meet these together with high stability. Current drug(More)
