Laser Annealing Nanoscale Carbons: Material Transformations

Vander Wal R., Abrahamson J., Gaddam C., Penn State University, US

Laser processing of materials is not new, but using lasers to anneal, bond and otherwise transform carbons is. Fundamental understanding of the dependence upon carbon structure, morphology and chemistry is critical to implementing this technology [...]

Physical properties of silver nanowire networks

Giusti G., Lagrange M., Langley D.P., Collins R., Jiménez C., Anikin M., Bréchet Y., Bellet D., Laboratoire des Matériaux et du Génie Physique (LMGP), FR

Silver nanowires were formed into random networks by using spin coating and spray deposition techniques. As a first step, electro-optical properties were optimized using an optimal nanowire density. The latter also depended on the nanowire [...]

The Effect of Thermal Annealing Processes on Graphene

Kumar K., Kim Y-S, Li X., Tian Y., Pallikaras A., Yang E.H., Stevens Institute of Technology, US

We demonstrate the impact of PMMA removal from CVD graphene by annealing in H2/Ar and ambient atmospheres as well as under vacuum on the Raman spectra and AFM topography of graphene. We find a broad [...]

Optimization of Phage-Based Magnetoelastic Biosensor Performance

Huang S., Yang H., Johnson M., Wan J., Chen I., Petrenko V.A., Chin B.A., Auburn University, US

A magnetoelastic (ME) platform coated with a bio-molecular recognition element (bacteriophage) for selective and specific recognition of Bacillus anthracis spores is described. ME materials have a mass-sensitive, characteristic, resonant frequency. In response to the binding [...]

Magnetic characteristics of FePt nanodots formed by a self-assembled nanodot deposition method

Yin C.K., Choi H., Bea J.C., Murugesan M., Yoo J-H, Fukushima T., Murakami Y., Tanaka T., Shindo D., Miyao M., Koyanagi M., Tohoku University, JP

FePt nanodot with L10 fct structure has attracted considerable attention owing to its potentials for new applications. FePt nanodots dispersed in a SiO2 film (FePt nanodot film) were formed by a self-assembled nanodots deposition (SAND) [...]

Micro Patterning Sensor Layers by Flame Deposition and Annealing

Tricoli A., Graf M., Mayer F., Kühne S., Hierlemann A., Pratsinis S.E., Swiss Federal Institute of Technology (ETH Zürich ), CH

A wafer-level, CMOS-compatible, dry process for in-situ synthesis, deposition and annealing of nanostructured, porous metal-oxide layers for gas sensors is presented. First, lace-like, nanostructured layers of pure or Pt-doped SnO2 featuring high porosity (98%) are [...]

Microwave Irradiation an Alternative Source for Conventional Annealing: A Study of Aluminum Oxide Thin Films by Sol-Gel Process

Phani A.R., Santucci S., University of L'Aquila, IT

Thin films of Al2O3 have been prepared by simple sol-gel process on to quartz substrates, and the as deposited films are subjected to annealing different temperatures and microwave irradiation at different powers. It is evident [...]

Investigation of Molecular Rearrangement by AFM Analysis of SAMs Annealing Process

Wu C-L, Hsieh H-Y, Tseng F-G, Chieng C-C, National Tsing Hua University, TW

Self assembly monolayers (SAMs) are easily prepared nano-film, and have been widely applied to improve device surface properties and biomaterial conjugation on substrates. Among various steps, annealing is one of the general processes for the [...]
