Year end link clean up

* “Poor Halo play prompts stabbing threat”:http://blog.seattlepi.com/seattle911/archives/231642.asp. Doesn’t seem unreasonable. I’ve heard campers threatened with worse. * “How Secure Is My Password”:http://howsecureismypassword.net/. No idea how accurate, but fun. 17 thousand years for my typical password. * “Rich on photobooks”:http://www.tongfamily.com/archives/2010/12/photobooks-for-christmas/. I […]

Silk and Timber electronics

“Paper and Lignin-based RFID tags”:http://www.physorg.com/news200760151.html. “Silk electronic metamaterials”:http://www.physorg.com/news200841751.html. Seems like we are not far away from having processing power embedded in damn near everything. Not lots of processing power, but enough to do identification and limited sensing. Interesting times.

Materials/Science grabbag

No time to blog, fall quarter starting, and travelling too. Dump of stuff that is interesting: * “Ultimate Productivity Blog”:http://productiveblog.tumblr.com/. I think that is clear. * “Paintable transistors”:http://www3.interscience.wiley.com/journal/122605160/abstract?CRETRY=1&SRETRY=0. Semiconducting polymer stable when applied at room temp, cool. * “Hydrophobic Nano […]

Thinking that intrigues me

* Touchable holography. Uses tracking cameras and directed ultrasound to create interaction and physical sensation. Cool demo. * Algortihmatic – online library of algorithms and IDE. Cool tho limited. * The LED’s dark secret. Droop in LED performance to be […]

Oriented Assembly of Metamaterials — Science

Oriented Assembly of Metamaterials — Stebe et al. 325 5937: 159 — Science — good article. “Such metamaterials may, for example, be used to create cloaking devices or light-based circuits based on manipulations of local optical electric fields rather than […]

Polymer Circuits

Good basic article on polymer circuits. I need to learn more about charge transport in polymers, i have a basic understanding of charge transport in metals and semiconductors and ionic fluids, i don’t really understand polymers. Polymer circuits potentially a […]

Ferroelectric or Electroactive Polymers

Had first lecture in ME 568 — Active and Sensing Materials. Topics include Ferroelectric polymers.  Paper here PVDF as a specific case. Strong piezo behaviour Penn State does a lot of work in these materials, as does Stanford

Spring Coursework

Continuing my educational adventure this spring: ME 568 Active and Sensing Materials:  Fundamental knowledge of the nano-structure property relations of active and sensing materials, and their devices. Examples of the active and sensing materials are: shape memory alloys (SMAs), ferromagnetic […]

Materials stuff that intrigues me

Targeted nanospheres find, penetrate, then fuel burning of melanoma | Science Blog. How Vision Sends Its Message To The Brain – the ability to record and study the reactions is what fascinates me Dynamic control of domain walls and Single […]

Molecular programming

Caltech researchers awarded $10M for molecular programming project. UW involved as well.  More info at the Molecular Programming Project: …we will develop new computer science principles for programming information-bearing molecules like DNA and RNA to create artificial biomolecular programs of […]

Materials science — circuits in everything

Flexible CNT circuits move on – nanotechweb.org.  Just one of many efforts to implant circuits onto papers, plastics, etc.  We are going to have processing power embedded in pretty much everything. Work on nanonet circuits — ok this stuff is […]

Interesting materials stuff

* Nanowire quantum dot counts electrons – nanotechweb.org — measuring current one electron at a time * Imaging using quantum-entangled photons — quantum entanglement stretches the brain. * Nanotube-coated pot boils water fast — the power of surface area. Maybe […]
