A short total synthesis of (±)-garcinol and (±)-isogarcinol, two endo-type B PPAPs with reported activity against methiciline resistant Staphylococcus aureus (MRSA), is presented. The separation of framework-constructing from framework-decorating steps and the application of two highly regio- and stereoselective Pd-catalysed allylations, that is, the Pd-catalysed decarboxylative Tsuji-Trost all...

Catalytic hydrosilylation represents a straightforward and atom-efficient methodology for the creation of C-Si bonds. In general, the application of homogeneous platinum complexes prevails in industry and academia. Herein, we describe the first heterogeneous single atom catalysts (SACs), which are conveniently prepared by decorating alumina nanorods with platinum atoms. The resulting stable mat...

Along with the success of the second Spanish Industrial Revolution, it was established one of the most important ceramics factories in Europe specialized in high resistance and quality floor tile. The great Royal Families of the moment such as Amadeo de Saboya (king of Spain), Imperial Hohenzollern family, Romanov (Imperial Russian family) and general Prim, came around to its installations for ...

Based on first-principles calculations, electronic properties of edge-functionalized zigzag graphene nanoribbons (ZGNRs) on SiO(2) substrate are presented. Metallic or semiconducting properties of ZGNRs are revealed due to various interactions between edge-hydrogenated ZGNRs and different SiO(2)(0001) surfaces. Bivalent functional groups decorating ZGNRs serve as the bridge between active edges...

Pb nanoclusters were deposited onto a suspended carbon nanowire (CNW), where in situ temperature variable observation was carried out by a transmission electron microscope. The heating temperature was up to 450 °C. Both the melting and evaporation of the Pb nanoparticles on the CNW were retarded when compared to the particles on the support frame. The obvious temperature difference of up to 10 ...

We study the notion of extensibility in functional data types, as a new approach to the problem of decorating abstract syntax trees with additional information. We observed the need for such extensibility while redesigning the data types representing Haskell abstract syntax inside Glasgow Haskell Compiler (GHC). Specifically, we describe a programming idiom that exploits type-level functions to...

We report the case of a 14-month-old girl suffering from cough and wheeze around Christmas. She was treated with anti-asthmatic drugs with no success, and 3 weeks later a chest X-ray revealed a LED bulb in the left main bronchus. This LED bulb came from a Christmas light garland decorating the Christmas tree. We discuss the different Christmas objects that can be inhaled by young children, the ...
