Abstract: Disclosed are cathodes comprising a conductive support substrate having an electrocatalyst coating containing nickel hosphide nanoparticles and a co-catalyst. The conductive support substrate is capable of incorporating a material to be reduced, such as CO2 or CO. A cocatalyst, either incorporated into the electrolyte solution, or into the conductive support, or adsorbed to, deposited on, or incorporated into the bulk cathode material, alters the electrocatalyst properties by increasing the carbon product selectivity through interactions with the reaction intermediates.

Abstract: The present invention relates in one aspect to a toy construction system for constructing and operating a remote controlled toy vehicle model. The system comprises: a plurality of modular toy elements; a modular toy vehicle base detachably connectable with the modular toy elements by means of coupling members so as to construct a toy vehicle model; and a remote control device adapted to control motorized functions in the modular toy vehicle base. The modular toy vehicle base further comprises an interaction sensor adapted to generate an interaction signal in response to a mechanical interaction with the toy vehicle model; wherein the toy construction system further comprises a processor with a signal analysis process. The signal analysis process is configured to perform an analysis of the interaction signal for indications of a building interaction according to predetermined criteria, and based on the analysis to generate an output indicative of a building interaction status.

Abstract: A reagent for use in detecting an analyte comprises a fluorescent energy donor and an energy acceptor, wherein the energy acceptor is of the general formula: and wherein the distance between the energy donor and the energy acceptor of the reagent is capable of modulation by a suitable analyte to be detected.

Abstract: The invention relates to fluorescent dyes comprising a triangulene structure in the form of a ring system of six, six-membered rings fused in a triangular fashion. The dyes are useful for visualisation of chemical compounds including polymer matrices for e.g. chromatographic separation and isolation of desirable chemical moieties, and for chemical library synthesis.
