Stretchable Gas and UV Sensors towards Wearable Electronics

Gutruf P., Walia S., Zeller E., Nili H., Sriram S., Bhaskaran M., RMIT University, AU

Electronics and sensors pervade all aspects of life, needing solutions to make them less obtrusive, which is where fully transparent electronics come into play. Our research focus has been to realise stretchable electronic devices with [...]

Influence of resist composition on demolding force in UV nanoimprint lithography

Amirsadeghi A., Lee J., Park S., Louisiana State University, US

We investigated the influence of the Young’s Modulus (E) of UV resist on the measured demolding force in UV-NIL by varying compositions of UV-curable polymers. We found that decreasing crosslinking content of the polymers decreases [...]

Nanomechanical characterization of UV curable hyperbranched polymers

Kim J., Chen Z., Chisholm B., Patel S., North Dakota State University, US

Hyperbranched polymers were explored to develop UV-curable, protective coatings for aluminum 2024-T3 and their viscoelastic and mechanical properties were characterized using nanoindentation techniques. The coating system consists of a hyperbranched polyester acrylate (CN2300, Sartomer Inc), [...]

Heating double wall carbon nanotubes with UV photons

Puech P., Bassil A., Flahaut E., Bacsa W.S., University Paul Sabatier, FR

Light absorption leads inevitably to electronic excitation and inelastic electron scattering, creating phonons and resulting in the increase of the lattice temperature. By using photons with energies significantly above the fundamental band gap of the [...]

3D Atomic Holographic Optical Storage Nanotechnology

Thomas M.E., Colossal Storage Corporation, US

Colossal Storage Inc. has exclusive license patent rights on new ways of non - contact reading and writing with non destructive reading of information to a ferroelectric molecule. These methods will be used to develop [...]

Resolution Enhancement in Nanoimprinting by Surface Energy Engineering

Jung G.Y., Wu W., Li Z., Wang S.Y., Tong W.M., Williams R.S., Hewlett Packard Laboratories, US

Nanoimprinting lithography was initiated as an alternative way to achieve nanoscale structures with high throughput and low cost. We have developed a UV-nanoimprint process to fabricate 34 by 34 crossbar circuits with a half-pitch of [...]

New Light Induced Molecular Switch allows Sterically Oriented Micrometer Sized Immobilization of Biomolecules

Snabe T., Neves-Petersen M.T., Fojan P., Klitgaard S., Neves-Petersen M.T., Petersen S.B., Aalborg University, DK

Fundamental knowledge on protein structures and the effect of ultraviolet light on these structures has paved the way for the development of a unique light-based immobilization technology that allows oriented protein immobilization onto micrometer sized [...]
