Preparation of Pickering emulsions through interfacial adsorption by soft cyclodextrin nanogels.

Beilstein J. Org. Chem. 11 , 2355-64, (2016)

Emulsions stabilized by colloidal particles are known as Pickering emulsions. To date, soft microgel particles as well as inorganic and organic particles have been utilized as Pickering emulsifiers. A...

Enzyme immobilization on silane-modified surface through short linkers: fate of interfacial phases and impact on catalytic activity.

Langmuir 30(14) , 4066-77, (2014)

We investigated the mechanism of enzyme immobilization on silanized surfaces through coupling agents (cross-linkers) in order to understand the role of these molecules on interfacial processes and the...

Molecular layer deposition of functional thin films for advanced lithographic patterning.

ACS Appl. Mater. Interfaces 3(2) , 505-11, (2011)

Photoresist materials comprise one of the main challenges faced by lithography to meet the requirements of electronic device size scaling. Here we report for the first time the use of molecular layer ...
