Synthesis and characterisation of mesoporous silica phases containing heteroatoms, and their cation exchange properties. Part 1. Synthesis of Si, Al, B, Zn substituted MCM-41 materials and their characterisation (2009)
Journal Article
Dyer, A., Newton, J., & Pillinger, M. (2009). Synthesis and characterisation of mesoporous silica phases containing heteroatoms, and their cation exchange properties. Part 1. Synthesis of Si, Al, B, Zn substituted MCM-41 materials and their characterisation. Microporous and Mesoporous Materials, 126(1-2), 192-200. https://doi.org/10.1016/j.micromeso.2009.06.002

The syntheses of mesoporous MCM-41 silica phases containing the heteroatoms Al, B, Zn, were carried out making use of trimethyl ammonium bromide surfactants of chain lengths C8–C16. The resulting materials were fully characterised by wet chemical and...

Cation exchange isotherms for MCM-41 phases. Microporous and Mesoporous Materials, 126(1-2), 201-212. https://doi.org/10.1016/j.micromeso.2009.06.003

Well characterised MCM phases containing aluminium and zinc heteroatoms were selected from those described in Part 1 [A. Dyer, J. Newton, M. Pillinger, Micropor. Mesopor. Mater. (2009), doi:10.1016/j.micromeso.2009.06.002] to this series. Cation exch...

Studies in modal density – its effect at low frequencies (2009)
Presentation / Conference
Wankling, M., & Fazenda, B. (2009, November). Studies in modal density – its effect at low frequencies. Presented at Reproduced Sound 25, Brighton

The ability to objectively measure the reproduction quality of a small room at low frequencies has long been desired. Over many years, there have been attempts to produce recommendations, metrics, and criteria by which to define a particular room. Th...
