Self-assembly of Functional Groups inside High Aspect Ratio Silicon Nanopores

Moghaddam S., Masel R., Shannon M., UIUC, US

A novel technique has been developed to assemble molecules with functional end groups inside pores of a nanoporous silicon membrane. A 20-um thick p-doped silicon membrane was anodized in HF electrolyte to produce 5-7 nm [...]

UV-NIL with optimal droplets

Sirotkin V., Svintsov A., Zaitsev S., IMT RAS, RU

A homogeneous residual layer thickness in nanoimprint lithography (NIL) is a serious problem in step and flash (UV-)NIL. Improvement of thickness homogeneity could be expected from optimized size of droplets at resist dispensing in case [...]

New Method for large Area NIL – SCIL

van Eekelen J., Weixlberger J., Suss MicroTec Lithography, DE

A new imprint technology for sub-50nm patterning will be introduced, bridging the gap between small rigid stamp application for best resolution and large area soft stamp usage with usual limited printing resolution below 200nm - [...]

Bimodal Macro- Mesoporous Silica Network

García Martínez J., Abellán G., Carrillo A.I., Linares N., University of Alicante, ES

Herein we described the synthesis of novel kind of silica materials prepared at room temperature in the presence of cationic surfactant, more specifically a quaternary amine (tallow tetraamine) to obtain silica-based materials with attractive properties, [...]

Nanostructured Biomolecular Assemblies Based on DNA-Protein Interactions

Sroga G.E., Dordick J.S., Rensselaer Polytechnic Institute, US

Directed, biologically-driven self-assembly has the potential to yield hybrid multicomponent architectures with applications ranging from nanoelectronic devices to smart drug delivery systems and responsive materials. To enable these applications, it is critical to gain control [...]

Micropatterning Layers by Flame Aerosol Deposition – Annealing

Tricoli A., Graf M., Mayer F., Kühne S., Hierlemann A., Pratsinis S.E., PTL, CH

The development of scalable methods, which effectively bind nanoparticles to surfaces and provide precise patterns, is a key step towards the commercial exploitation of the distinctive properties of nanoparticles. In this context, the direct deposition [...]

Dynamic study on Nanometer size square Permalloy (NiFe) antidot arrays; use as Monolithic Microwave localize band-pass filter

Kuanr B.K., Malkinski L.M., Yu M., Scherer D., Camley R., Celinski Z., University of Colorado at Colorado Springs, US

Arrays of magnetic antidots (holes) have attracted extensive attention these days due to their potential application for high density data storage. In this investigation we fabricated antidots by means of electron-beam lithography and lift-off techniques [...]

Fabrication and optical properties of nanoscale arrays of Au and Pd in polymers

Atre S.V., Bhowmik S., Valmikanathan O.P., Ostroverkhova O., Oregon Nanoscience & Microtechnologies Institute, US

We report the fabrication of regular repeat structures of Au and Pd square islands embedded in polymethyl methacrylate (PMMA) and polycarbonate (PC). Using focussed ion beam (FIB), square islands were machined over a 5 micron [...]

Synthesis of one-dimensional titanium dioxide nanostructures

Cottam B., Chyla S., Menzel R., Bismarck A., Shaffer M., Imperial College London, UK

Finely structured titanium dioxide is a technological material of long-standing importance for many applications including pigments and catalysis. There is growing interest in smaller, truly nano-sized titanium dioxide particles with well-defined crystallinity and a range [...]

Surface plasmon polariton assisted organic solar cells

Kim C., Kim J., Lee J-Y, Peumans P., Kim C., Kim J., Duke University, US

A fundamental limitation of organic photovoltaic (OPV) cells is due to the trade-off between light absorption and exciton diffusion. We show that light absorption in an OPV cell can be enhanced by replacing a conventional [...]
