Controlling interlayer diffusion to achieve sustained, multiagent delivery from layer-by-layer thin films.
We present the fabrication of conformal, hydrolytically degradable thin films capable of administering sustained, multiagent release profiles. Films are constructed one molecular layer at a time by using the layer-by-layer, directed-deposition technique; the subsequent hydrolytic surface erosion of these systems results in the release of incorporated materials in a sequence that reflects their ...

متن کاملUltrafast Atomic Layer-by-Layer Oxygen Vacancy-Exchange Diffusion in Double-Perovskite LnBaCo2O5.5+δ Thin Films
Surface exchange and oxygen vacancy diffusion dynamics were studied in double-perovskites LnBaCo2O5.5+δ (LnBCO) single-crystalline thin films (Ln = Er, Pr; -0.5 < δ < 0.5) by carefully monitoring the resistance changes under a switching flow of oxidizing gas (O2) and reducing gas (H2) in the temperature range of 250 ~ 800 °C. A giant resistance change ΔR by three to four orders of magnitude in ...
متن کاملLayer-by-layer epitaxial thin films of the pyrochlore Tb2Ti2O7.
Layer-by-layer epitaxial growth of the pyrochlore magnet Tb2Ti2O7 on the isostructural substrate Y2Ti2O7 results in high-quality single crystal films of up to 60 nm thickness. Substrate-induced strain is shown to act as a strong and controlled perturbation to the exotic magnetism of Tb2Ti2O7, opening up the general prospect of strain-engineering the diverse magnetic and electrical properties of...
متن کاملSculptured Layer-by-Layer Films
The precise assembly of nanostructured materials into two (2D) and three-dimensional (3D) periodic microscopic arrays is achieved by employing various assembling technologies such as microparticle self-organization, photolithography, holographic lithography, selective chemical etching, ink printing, laser-based polymerization, selective responsive grafting, and inversion of bilayers. Soft litho...
