Detailed studies of graphene grown on C-face SiC

Virojanadara C., Linkoeping University, SE

The registry of adjacent graphene layers grown on the C-terminated SiC surface has been reported to be dramatically different compared to graphene grown on the Si-terminated SiC(0001) surface. Whereas Si-face graphene exhibits sharp spots in [...]

Superhydrophobic Surfaces by Supercritical Fluid Technology

Ek Å., Turner C., Werner O., Wågberg L., SweTree Technologies, SE

The term superhydrophobicity is used to describe the effect when a water droplet is rolling off a surface instead of sliding. Superhydrophobic surfaces, like the surface of a Lotus leaf, have water-repellant and self-cleaning properties. [...]

Structuring Membrane Proteins as Tools in Material Science

Mille C., Corkery R.W., YKI, Institure for Surface Chemistry, SE

Two membrane proteins derived from yeast, Yop1p and Rtn1p, have been engineered, heterogeneously expressed and purified. Both proteins are membrane spanning and can be found in all eukaryotes in which they are used for structural [...]

Effect of local curvature on the interaction between hydrophobic surfaces

Hansson P., Swerin A., Thormann E., Claesson P.M., Schoelkopf J., Gane P.A.C., YKI, Institute for surface chemistry, SE

Previous measurements of the attractive interaction between hydrophobic macroscopic surfaces have showed that long-range forces that are considerably stronger than the van der Waals force dominate the interaction Silica nanoparticles have been deposited on substrates [...]

Low Cost Paper Based Bowtie Tag Antenna for High Performance UHF RFID Applications

Amin Y., Prokkola S., Shao B., Hållstedt J., Chen Q., Tenhunen H., Zheng L-R, Royal Institute of Technology (KTH), SE

In this paper, we have realized a bowtie antenna for UHF RFID Tag with extended round corners for the first time printed on paper substrate. The state of the art CAD tool Ansoft® HFSS is [...]

Silex offers sub 50 um pitch for through wafer connections in up to 600 um thick substrates

Bauer T., Silex Microsystems, SE

The silicon via process developed by Silex offers sub 50 um via pitch for through wafer connections in up to 600 um thick wafers. Silex via process enables MEMS designs with significantly reduced die size [...]

photonic nano crystal and its impact

Nzulu G.K, Linkoping University, SE

From all the experiments carried above, Photonic crystal, so far has shown to have a very promising future and it is assumed that in the next decades new technologies would be seen. It is estimated [...]

Nanogaps for fabrication of Molecular Devices

Kabir M.S., Enokson P., Chalmers University of Technology, SE

The development of different alternative technologies to fabricate various types of nanoscale devices based on non-conventional materials such as molecules and clusters are here reported. We had two different approaches to fabricate nangaps though there [...]

The Effect of Gold Nanoparticles on Dendritic Cells

Vallhov H., Qin J., Johansson S., Muhammed M., Gabrielsson S., Scheynius A., Karolinska Institutet, SE

Recent biological applications have been focusing on using gold nanoparticles for e.g. drug and gene delivery. There is however little information available concerning what influence such particles have on the immune system, e.g. on dendritic [...]

Nano Scale Autonomous Error-Tolerant (AET) Cellular Network

Liu J., Weerasekera R., Zheng L-R, Tenhunen H., Royal Institute of Technology (KTH), SE

we propose a bottom-up approach using nano-CMOS hybrid Autonomous Error-Tolerant (AET) cellular network architecture. In our approach, each hexagonal AET cell consists of a nano-core dedicated for local computing, CMOS cell peripherals responsible for cell [...]
