  • FUNCTIONALISED ALUMINA ADSORBENT MATERIALS FOR REMOVAL OF CONTAMINANTS FROM WATER
    Publication number: 20230264170
    Abstract: A composition is provided for removal of a target substance from a fluid stream. The composition may be used to remove polyfluorinated alkyl substances (PFAS) from water. The composition comprises a support material comprising an alumina; and a sorbent molecule that comprises a core polymer; wherein the core polymer is covalently linked to the support material; and wherein the sorbent molecule further comprises one or more covalently linked sorbent groups. Processes for removal of target substances such as PFAS are also provided.

  • SILICONE ELASTOMER COMPOSITION
    Publication number: 20220162448
    Abstract: The present invention provides a tin-free, room temperature curable silicone elastomer composition, wherein the uncured composition is a putty. The silicone elastomer composition comprises a) an end-capped base polymer, wherein the base polymer comprises a polysiloxane or mixture of polysiloxanes, and wherein the end-capped base polymer comprises terminal di-(C1-4)alkoxy silyl groups; b) at least one amorphous filler; c) 15.1 to 60 parts by weight of at least one spherical filler for each 100 parts by weight of base polymer; and d) a curing catalyst consisting of one or more selected from the group consisting of organic titanates and organic zirconates. The terminal dialkoxy silyl groups of the base polymer can be dimethoxy silyl groups. The at least one amorphous filler can be selected from the group consisting of fumed silica, fumed alumina, carbon black, precipitated silica, precipitated calcium carbonate, surface-treated calcium carbonate and mixtures thereof.

  • Quantum dot compositions
    Patent number: 9663710
    Abstract: It has been discovered that certain silicon-containing, surface-modifying ligands can be used to make semiconductor nanoparticles (quantum dots) more compatible with polysiloxanes. Quantum dots dispersed in a polysiloxane matrix may be used, for example, in light-emitting devices to alter the emission spectrum of such devices.
