The present application discloses a fouling control coating composition comprising a polysiloxane-based binder system, 0.01-20% by dry weight of one or more hydrophilic-modified polysiloxanes, and one or more biocides. The hydrophilic-modified polysiloxane may be a poly(oxyalkylene)-modified polysiloxane, e.g. a polysiloxane having grafted thereto poly(oxyalkylene) chains and/or having incorporated in the backbone thereof poly(oxyalkylene) chains. The poly(oxyalkylene) may e.g. be selected from polyoxyethylene, polyoxypropylene and poly(oxyethylene-co-oxypropylene) (polyethylene glycols/polypropylene glycols). The application further discloses a marine structure comprising on at least a part of the outer surface thereof an outermost coating prepared from the coating composition. Moreover, the application discloses the use of the combination of non-reactive hydrophilic-modified polysiloxanes and biocides, wherein the weight ratio between the hydrophilic-modified polysiloxanes and the biocides is in the range 1:0.2 to 1:6, for improving the antifouling properties of a polysiloxane based coating composition.

摘要:
A photoneutron conversion target for generating photoneutrons by directing an x-ray beam at the photoneutron conversion target includes an elongated body having a first end and a second end. When the photoneutron conversion target is in use, the x-ray beam enters the body and propagates in a direction from the first end to the second end. The body of the photoneutron conversion target is shaped such that propagation of the x-ray beam is substantially proportionate to an intensity distribution of the x-ray beam, so that the greater an intensity of x-rays of the x-ray beam, the greater the propagation distance of the x-rays within the body of the photoneutron conversion target. The photoneutron conversion target according to the invention can make full use of the x-ray beam so as to increase a yield of photoneutrons.
