Castelijns, H.J. (author), Huinink, H.P. (author), Pel, L. (author), Zitha, P.L.J. (author)The coupled mass transfer and chemical reactions of a gel-forming compound in a two-phase system were studied in detail. Tetra-methyl-ortho-silicate (TMOS) is often used as a precursor in sol-gel chemistry to produce silica gels in aqueous systems. TMOS can also be mixed with many hydrocarbons without chemical reaction, which allows for various...journal article 2006

Carneiro, J.T. (author), Yang, C.C. (author), Moma, J.A. (author), Moulijn, J.A. (author), Mul, G. (author)Gold deposition on Hombikat UV100 was found to negatively affect the activity of this Anatase catalyst in selective photo-oxidation of cyclohexane. By ammonia TPD and DRIFT spectroscopy it was determined that the Au deposition procedure leads to a significant decrease in OH-group density (mol m?2 BET) on Hombikat, suggesting that the amount of...journal article 2009

(author)The present work reveals a new and simple strategy, a one-step sol–gel procedure, to encapsulate a low water-soluble drug in silica mesostructured microparticles and to improve its release in physiological media. The synthesis of these new materials is based on the efficient solubilisation of a poorly water-soluble drug in surfactant micelles ...journal article 2011

Tran, T.H.Y. (author)Carbon capture and storage (CCS) can significantly contribute to the reduction of the emission of the greenhouse gas CO2. Capture by means of CO2 sorption or membrane-based separation processes is a promising way for achieving decarbonization of fuel or flue gas cleaning. In the field of separation and also purification of hydrogen, membrane...doctoral thesis 2011

Recloux, I. (author), Olivier, M.G. (author)Among the different alternative surface treatments developed in view of the coming prohibition of chromates in aeronautic applications, sol-gel coatings show very promising properties. These layers provide a barrier against aggressive environments. Moreover, their performance can be improved by introducing inhibitive agents in the coating....conference paper 2013

AbdolahZadeh, M. (author), Esteves, A.C.C. (author), Van der Zwaag, S. (author), Garcia Espallargas, S.J. (author)Sol-gel technology is increasingly being used in coatings for corrosion protection and adhesion improvement. So far, the self-healing concept in sol-gel coatings has only been approached from extrinsic healing perspective (i.e. use of nano and micro carriers of corrosion inhibitors) [1]. Despite the benefits of this approach, the damaged area...conference paper 2013

Poltorak, L. (author), van der Meijden, N. (author), Oonk, S. (author), Sudhölter, Ernst J. R. (author), de Puit, M. (author)The behaviour of acid phosphatase at an electrified liquid–liquid interface was studied in this work. It was found that only the protonated form of the protein can undergo interfacial adsorption which is affected by the pH of the aqueous phase. With ion transfer voltammetry we could detect acid phosphatase in concentrations as low as 0.1 μM....journal article 2018
