Chemistry and properties of nanocrystals of different shapes.

Recent developments have greatly improved the sensitivity of optical sensors based on metal nanoparticle arrays and single nanoparticles. We introduce the localized surface plasmon resonance (LSPR) sensor and describe how its exquisite sensitivity to size, shape and environment can be harnessed to detect molecular binding events and changes in molecular conformation. We then describe recent progress in three areas representing the most significant challenges: pushing sensitivity towards the single-molecule detection limit, combining LSPR with complementary molecular identification techniques such as surface-enhanced Raman spectroscopy, and practical development of sensors and instrumentation for routine use and high-throughput detection. This review highlights several exceptionally promising research directions and discusses how diverse applications of plasmonic nanoparticles can be integrated in the near future.

Correction: Black titanium dioxide (TiO2) nanomaterials

Organic light-emitting diode (OLED) devices were fabricated with a structured polymer-cathode interface. The devices have a layered structure indium tin oxide/poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)/poly(2-methoxy-5-[(2′-ethylhexyl)oxy]-p-phenylenevinylene)/Al. The light-emitting polymer layers were patterned via a stamp imprinting process, followed by vapor deposition of the cathode. Devices employing the structured cathode showed improved electron injection and increased brightness when compared to conventional flat cathode devices. Electrostatic modeling of the structured cathode geometry revealed localized increase in electric field leading to enhanced electron tunneling through the polymer-cathode interface. Thus, improved OLED performance was demonstrated from cathode microstructuring.

A cost‐effective crosslinked β‐cyclodextrin polymer for the rapid and efficient removal of micropollutants from wastewater

Porous ZnS/ZnSe nanosheets (NSs) with different ratios of the two components are fabricated by a facile two-step solvothermal method with the comparison to ZnS and ZnSe NSs. ZnS/ZnSe NSs have the similar geometrical morphology with the pure ZnS and ZnSe NSs, and show a better absorption in the UV light region as well as in the visible-light region. Compared with pure ZnS or ZnSe, ZnS/ZnSe NSs display an outstanding photodegradation ability for decolorization of methyl orange (MO) under visible light irradiation. ZnS/ZnSe NSs with a molar ratio of ZnS to ZnSe as 1:1 exhibit the highest photocatalytic activity and a good photocatalytic stability, and their degradation rate constants are nearly 53 and 6 times higher than those of pure ZnS and ZnSe NSs.
