The paper details with of the preparation and physicochemical characterisation of nanoand microstructured TiO2 doped with Fe and Co produced by the sol-gel method using titanium alkoxide as the precursor of titania as well as iron or cobalt nitrates as dopant sources. Fe and Co doped TiO2 materials were successfully prepared with two different methods. The effect of the dopant type on the synth...

Background: Residential wood combustion is now recognized as a major particle source in many developed countries, and the number of studies investigating the negative health effects associated with wood smoke exposure is currently increasing. The combustion appliances in use today provide highly variable combustion conditions resulting in large variations in the physicochemical characteristics ...

Self-assembly is a ubiquitous physicochemical phenomenon. It is inherent to molecular recognition effects in the biological domain, and thus presents a basis for understanding the constitution and dynamic organization of living beings. However, it is argued in this paper that the very notion of self-assembly presents an incorrect and misleading one for the physical effects that it stands for. S...

In analytical chemistry, silica gel plays a pre-dominant role in separation science. It is the most important stationary phase in chromatography and electrophoresis. Separation efficiency is directly dependent on the quality and physical properties of the chromatographic bed. Therefore, methods for the physicochemical characterisation of silica stationary phases have been developed over the pas...
