Bioimpacts. 2011;1(4):225-8. doi: 10.5681/bi.2011.032. Epub 2011 Dec 13.

INTRODUCTION: Arterial bifurcations are susceptible locations for formation of atherosclerotic plaques. In the present study, steady blood flow is investigated in a bifurcation model with a non-planar branch.METHODS: The influence of different bifurcation angles and non-planar branch is demonstrated...

Surfactants are broadly used to improve wetting properties of aqueous formulations. The improvement is achieved by essential reduction of liquid/air and solid/liquid interfacial tensions resulting in the decrease of contact angle. For moderately hydrophobic substrates, there is a range...

Encapsulation of Graphene in the Hydrophobic Core of a Lipid Bilayer.

Langmuir : the ACS journal of surfaces and colloids

Theoretical simulations have predicted that a lipid bilayer forms a stable superstructure when a sheet of graphene is inserted in its hydrophobic core. We experimentally produced for the first time a lipid-graphene-lipid assembly by combining the Langmuir-Blodgett and the...
