Patent number: 9878356Abstract: The invention relates to composite adsorbent materials, and in particular, to highly porous carbon-based composite materials for the adsorption and stabilization of inorganic substances. The composite adsorbent material comprises a porous carbon carrier matrix and an adsorbent species, wherein the adsorbent species is precipitated within the pores of the carrier matrix. The invention extends to various uses of such adsorbent materials, for example in water purification, recovery of metals from waste streams and remediation applications, and where the adsorbant material is amended into soil, waste etc. for the purpose of breaking pollutant-receptor linkages.Type: GrantFiled: July 31, 2013Date of Patent: January 30, 2018Assignees: The University of Surrey, The Forestry CommissionInventors: Franciscus Antonius Anna Maria De Leij, James Stratford, Helen Sneath, Tony Hutchings

Patent number: 9743675Abstract: Antimicrobial compositions comprising a terpenoid in combination with an antimicrobial agent are provided. In addition, uses of such compositions in various applications involving preventing, combating or treating microbial infections, or preventing microbial growth or establishment are provided.Type: GrantFiled: September 10, 2010Date of Patent: August 29, 2017Assignee: UNIVERSITY OF SURREYInventors: Franciscus Antonius Anna Maria De Leij, Mina Kalantarzadeh, Dulcie Mulholland, Tony Hutchings
-
Patent number: 9320259Abstract: The invention relates to a method for preparing antimicrobial material. The method comprises heating material comprising wood or bark or material derived therefrom, under conditions sufficient to render the material antimicrobial. The invention also relates to antimicrobial materials prepared by such methods, and to various uses of the antimicrobial materials, for example in reducing microbial activity in animal bedding, such as that which is used in poultry farming.Type: GrantFiled: November 12, 2009Date of Patent: April 26, 2016Assignee: UNIVERSITY OF SURREYInventors: Franciscus Antonius Anna Maria De Leij, Mina Kalantarzadeh, Tony Hutchings
