Molecular recognition on acoustic wave devices [PDF]

open access: yes, 1992
Microporous thin films composed either of zeolite crystals embedded in sol-gel derived glass or of a molecular coupling layer, zeolite crystals and a porous silica overlayer, were formed on the gold electrodes of Quartz Crystal Microbalances (QCM). The

Protein thin film machines [PDF]

open access: yesNanoscale, 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.

Effect of substrate temperature on structural and optical properties of cadmium sulfide thin films prepared by evaporation thermal deposition

open access: yesAl-Mustansiriyah Journal of Science, 2019
In this research , we study the effect of substrate temperature (423K and 473K) on structural and optical properties for thin films of cadmium sulfide (CdS) by evaporation thermal deposition method on glass substrates and the thickness was about (390nm ...

Nano Scaled Checkerboards: A Long Range Ordering in NiCoMnAl Magnetic Shape Memory Alloy Thin Films with Martensitic Intercalations

open access: yesApplied Sciences, 2022
Magnetic shape memory Heusler alloys, such as NiCoMnAl, are considered as promising candidates for magnetocaloric cooling applications. Grown in thin film systems of adjacent layers with austenite and martensite crystal structures of almost equal ...

Probing viscoelastic properties of a thin polymer film sheared between a beads layer and quartz crystal resonator [PDF]

open access: yes, 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 ...

Improvement of dielectric loss of doped Ba0.5Sr0.5TiO3 thin films for tunable microwave devices [PDF]

open access: yes, 2003
Al2O3-Ba0.5Sr0.5TiO3 (Al2O3-BST) thin films, with different Al2O3 contents, were deposited on (100) LaAlO3 substrate by pulsed laser deposition (PLD) technique.

Understanding the Formation Process of Perovskite Layers Grown by Chemical Vapour Deposition

open access: yesFrontiers 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).

Surface Acoustic Waves in Thin Films Nanometrology [PDF]

open access: yes, 2015
Thin films nanometrology is an emerging field in nanoscience as the synthesis, processing and applications of nanostructured thin films require an in-depth knowledge of their elastic constants. The elastic energy of a surface acoustic wave propagating in

Single-graded CIGS with narrow bandgap for tandem solar cells

open access: yesScience 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
