Probing viscoelastic properties of a thin polymer film sheared between a beads layer and quartz crystal resonator [PDF]
, 2009 We report measurements of viscoelastic properties of thin polymer films of 10-100 nm at the MHz range. These thin films are confined between a quartz crystal resonator and a millimetric bead layer, producing an increase of both resonance frequency and ...

Protein thin film machines [PDF]
Nanoscale, 2010 We report the first example of microcantilever beams that are reversibly driven by protein thin film machines fueled by cycling the salt concentration of the surrounding solution. We also show that upon the same salinity stimulus the drive can be completely reversed in its direction by introducing a surface coating ligand.

Understanding the Formation Process of Perovskite Layers Grown by Chemical Vapour Deposition
Frontiers in Energy Research, 2022 This work aims at extending the understanding of the formation processes of (Cs0.07FA0.93)PbI3 perovskite layers deposited by a two-step vapour method. In a first step, an inorganic CsI/PbI2 precursor stack is deposited by thermal evaporation (TE).

Single-graded CIGS with narrow bandgap for tandem solar cells
Science and Technology of Advanced Materials, 2018 Multi-junction solar cells show the highest photovoltaic energy conversion efficiencies, but the current technologies based on wafers and epitaxial growth of multiple layers are very costly. Therefore, there is a high interest in realizing multi-junction
