Abstract: A protective shield (100) comprises a body (105) for protecting a user from a projectile or impact, the body comprising a front strike face (110) and an opposing rear face (115); and a connector arrangement (125, 126) provided on the body adapted so as to allow the shield to connect to an adjacent protective shield, wherein the strike face has a perimeter defined by the edges of the strike face; and wherein the connector arrangement is arranged so that an adjacent protective shield can be connected to the connector arrangement with the body of the adjacent protective shield abutting and/or overlapping with the strike face of the protective shield at any point about the perimeter of the strike face.

Abstract: An ink comprises (i) a carrier; (ii) graphene and/or graphene oxide particles dispersed in the carrier; and (iii) a viral active and/or anti-microbial component adhered to the graphene and/or graphene oxide particles.

Abstract: A composite structure comprises a plurality of first layers each comprising graphene; and a plurality of second layers each comprising an aerogel, wherein the first and second layers alternate in the composite structure. A method for manufacturing a composite structure comprising first and second layers comprises providing a plurality of the second layers, each second layer comprising an aerogel, providing a plurality of first layers, each layer comprising graphene; and arranging the first and second layers so that the layers form a composite structure in which the plurality of first and second layers alternate.

Abstract: A device for collecting electricity from the atmosphere comprises: a collecting element adapted to draw electricity from the atmosphere; an electrically conductive element electrically connected to the collecting element for transmitting electricity collected by the collecting element to an output; and a support member capable of holding the collecting element in an elevated position, wherein the electrically conductive element comprises a composite structure extending at least partially along its length, the composite structure comprising a first layer comprising graphene.
