摘要： A particle is disclosed which comprises a core surrounded by a shell which comprises a plurality of nanoparticles of a magnetic material, the shell being surrounded by a continuous outer shell which comprises a non-magnetic material. The particle can be prepared by a process comprising: a first step of providing a core; a second step of adsorbing an inner shell to the core; a third step of providing a plurality of nanoparticles of a magnetic material; a fourth step of adsorbing the nanoparticles to the inner shell; and a fifth step of synthesising an outer shell surrounding the particle. The particle can exhibit the effective bulk properties of a superparamagnetic particle, and the effective surface properties of a non-magnetic particle.

摘要： A UV screening composition comprising novel particles which are capable of absorbing UV light so that electrons and positively charged holes are formed within the particles is disclosed. These particles comprise a host lattice incorporating a second component to provide luminescence trap sites and/or killer sites, said second component being niobium, vanadium, antimony, tantalum, strontium, calcium, magnesium, barium, molybdenum or silicon.
