Nanostructured MnO(2) exhibits a high turnover frequency for oxygen evolution under visible light and high stability in strong acidic conditions.

A dual visible light photoredox and gold-catalysed C(sp(2))-C(sp(2)) cross coupling is described. The success of this mild, oxidant- and base-free cross coupling is highly dependent on the amount of water added. Mechanistic studies show two distinct pathways depending on the gold catalyst employed: transmetallation of the arylboronic acid with gold(i) occurs prior to oxidation of gold(i) to gol...

The highest possible resolution for printed colour images is determined by the diffraction limit of visible light. To achieve this limit, individual colour elements (or pixels) with a pitch of 250 nm are required, translating into printed images at a resolution of ∼100,000 dots per inch (d.p.i.). However, methods for dispensing multiple colourants or fabricating structural colour through plasmo...

A highly efficient and chemoselective method for the synthesis of diaryl disulfides is developed via a visible light-promoted coupling of readily accessible arenediazonium tetrafluoroborates and CS2. This practical and convenient protocol provides a direct pathway for the assembly of a series of disulfides in an environmentally friendly manner with good to excellent yields.

A novel multiresponsive function of monoclinic BiVO(4) has been put forward for the first time, and loosely packed monoclinic BiVO(4) nanoellipsoids with many exposed crystal planes have been designed and synthesized in order to improve their smart multiresponses to visible light, trace gas and temperature.

A circular holographic display that consists of phase-only spatial light modulators is used to reconstruct images in visible light from digital holograms recorded under infrared (10.6 μm) illumination. The reconstruction yields a holographic digital video display of a three-dimensional ghostlike image of an object floating in space where observers can move and rotate around it.

The options premiums are frequently used to obtain probability density functions (pdfs) for the prices of the underlying assets. When these assets are bank deposits or notional Government bonds it is possible to compute probability measures of future interest rates. Recently, in the literature there have been many papers presenting methods of how to estimate pdfs from options premiums. Neverthe...
