Abstract With the assistance of microwave irradiation, greenish‐yellow luminescent graphene quantum dots (gGQDs) with a yield (QY) up to 11.7% are successfully prepared via cleaving oxide (GO) under acid conditions. The and reduction processes accomplished simultaneously using treatment without additional reducing agent. When gGQDs further reduced NaBH 4 , bright blue (bGQDs) obtained QY as high 22.9%. Both GQDs show well‐known excitation‐dependent PL behavior, which could be ascribed...
This article describes a highly effective catalytic asymmetric epoxidation method for olefins using potassium peroxomonosulfate (Oxone, Dupont) as oxidant and fructose-derived ketone (1) catalyst. High enantioselectivies have been obtained trans-disubstituted trisubstituted which can bear functional groups such tributylsilyl ether, acetal, chloride, ester. The enantiomeric excesses cis-olefins terminal are not high yet. current shows that the catalyst efficiency is enhanced dramatically upon...

An advanced electrogenerated chemiluminescence (ECL) immunosensor proposed sensitive detection human IgG (HIgG) by using as‐prepared P‐GR‐CdSe The composite film shows high ECL intensity, good electronic conductivity, fast response, and satisfactory stability, all which holds great promise biosensors with improved sensitivity. After two...
Coating individual bacterial cells with conjugated polymers to endow them more functionalities is highly desirable. Here, we developed an in situ polymerization method coat polypyrrole on the surface of Shewanella oneidensis MR-1, Escherichia coli, Ochrobacterium anthropic or Streptococcus thermophilus. All these as-coated from different species displayed enhanced conductivities without affecting viability, suggesting generality our coating method. Because their excellent conductivity,...
Abstract DNAzymes have enjoyed success as metal ion sensors outside cells. Their susceptibility to metal‐dependent cleavage during delivery into cells has limited their intracellular applications. To overcome this limitation, a near‐infrared (NIR) photothermal activation method is presented for controlling DNAzyme activity in living The system consists of three‐stranded precursor (TSDP), the hybridization which prevents from being active. After conjugating TSDP onto gold nanoshells and upon...
A new, ultrasensitive photoelectrochemical immunosensing platform was established on the basis of CdSeTe@CdS:Mn core–shell quantum dots-sensitized TiO2 coupled with signal amplification CuS nanocrystals conjugated antibodies. In this proposal, carcinoembryonic antigen (CEA, Ag) selected as an example target analyte to show analytical performances platform. Specifically, TiO2-modified electrode first assembled CdSeTe alloyed dots (AQDs) via electrostatic adsorption assisted by oppositely...
All-inorganic nanocrystals (NCs) are of great importance in a range electronic devices. However, current all-inorganic NCs suffer from limitations their optical properties, such as low fluorescence efficiencies. Here, we develop general surface treatment strategy to obtain intensely luminescent (ILANs) by using designed metal salts with noncoordinating anions that play dual role the process: (i) removing original organic ligands and (ii) binding unpassivated Lewis basic sites preserve...
A simple sonochemical route was developed for the crystal growth of uniform silver nanoplates and ringlike gold nanocrystals in a N,N-dimethylformamide solution. The platelike structures were generated from selective on different planes presence poly(vinylpyrrolidone) ultrasonic-assisted Ostwald ripening processes. solution served as templates synthesis crystals via displacement reaction. Both nanorings highly oriented single with (111) basal planes.
It is demonstrated that many previously reported Lyapunov-based stability conditions for time-delay systems are equivalent to the robust analysis of an uncertain comparison system free delays via use scaled small-gain lemma with constant scales. The novelty this note stems from fact it unifies several existing results under same framework. In addition, offers insights on how new, less conservative can be developed.
