Carrier-mediated drug delivery has emerged as a powerful methodology for the treatment of various pathologies. The therapeutic index of traditional and novel drugs is enhanced via the increase of specificity due to targeting of drugs to a particular tissue ...
We have compared calorimetric measurements with the nonlinear optical technique vibrational sum frequency scattering to investigate interface-solvent effects in colloidal gelation transitions. This allows us to explain the difference in gelation behaviour ...
We discuss features of simple inter-particle potentials which are able to generate low-packing fraction arrested states, i.e. gels, in the absence of a macroscopic phase separation phenomenon. We suggest that the ratio between surface and bulk free energy ...
The interactions and structural formation of polyelectrolytes in solution and environmental stimuli-responsive water-soluble polymers are subjects of intense academic research, development, and application. An increasing number of novel materials are being ...
Organic–inorganic hybrid materials were prepared using the sol–gel process in order to improve the scratch resistance of poly(methyl methacrylate) (PMMA) substrates. Sol–gel solutions based on tetraethoxysilane and α,ω-triethoxysilane terminated polycaprol ...
The Derjaguin approximation states that the interaction force between two curved surfaces is proportional to their effective radius, whereby the inverse effective radius is the arithmetic mean of the inverse curvature radii of the surfaces involved. The pr ...
Holographic gratings are recorded in colloidal suspensions of silver nanoparticles by utilizing interfering nanosecond pulses. The diffraction efficiency is measured with continuous-wave light. An instantaneous response together with a transient grating ar ...
We describe devices in which optics and fluidics are used synergistically to synthesize novel functionalities. Fluidic replacement or modification leads to reconfigurable optical systems, whereas the implementation of optics through the microfluidic toolki ...
We studied spark-generated shockwaves propagating inside stable water drops produced in microgravity. The closed and isolated liquid geometry results in a unique confinement of shockwaves, since the latter bounce of the free surface. This setting results i ...
The size dependence of electron-phonon coupling rate has been investigated by femtosecond transient absorption spectroscopy for gold nanoparticles (NPs) wrapped in a shell of sulfate with diameter varying from 1.7 to 9.2 nm. Broad-band spectroscopy gives a ...
