Abstract: A catalyst layer comprising: (i) a platinum-containing electrocatalyst; (ii) oxygen evolution reaction electrocatalyst; (iii) one or more carbonaceous materials selected from the group consisting of graphite, nanofibres, nanotubes, nanographene platelets and low surface area, heat-treated carbon blacks wherein the one or more carbonaceous materials do not support the platinum-containing electrocatalyst; and (iv) proton-conducting polymer and its use in an electrochemical device is disclosed.

Abstract: The present invention provides a catalysed decal transfer substrate comprising a decal transfer substrate, an electrocatalyst later, and a layer D between the decal transfer substrate and the electrocatalyst layer which comprises an ion-conducting polymer and a carbon material. The layer D is configured such that, upon transfer of the electrocatalyst layer to a surface, at least a portion of the layer D remains attached to and is transferred with the electrocatalyst layer.

Abstract: An isolated lantibiotic is provided comprising amino acid sequence SEQ. ID No. 2 and at least one of amino acid sequences SEQ. ID No. 4 and SEQ. ID. No 6. Also provided is use of the lantibiotic in the treatment or prevention of infection by Group B Streptococcus or Corynebacterium xerosis. The invention further relates to isolated S. hominis strains and use of same in producing the lantibiotic. A vector is provided comprising nucleotides sequences for producing the lantibiotic.

Abstract: The invention includes a reinforced membrane-seal assembly that comprises a reinforcing component, ion-conducting material, and seal material. The reinforcing component comprises a central region comprising a plurality of apertures extending from a first surface to a second surface of the reinforcing component, the central region having a first aperture area density; an inner peripheral border region surrounding the central region, where the inner peripheral border region is devoid of apertures; and an outer peripheral border region comprising a plurality of apertures extending from the first surface to the second surface of the reinforcing component, the outer peripheral border region having a second aperture area density. The outer peripheral border region surrounds the inner peripheral border region.
