Estatus al lunes 7 de Diciembre

Como platicamos hoy en la reunión que tuvimos, el proyecto parece factible y apropiado para que lo realicen los estudiantes. La dirección del proyecto recaerá principalmente en Roberto y Felix, mientras que la supervisión-asesoría quedará en Jorge y conmigo. El facilitar los recursos financieros y administrativos para que pueda ocurrir y desarrollarse el proyecto es mi responsabilidad, aunque si existen facilidades ya existentes (de equipo, material o infraestructura) en algún laboratorio, son bienvenidas.

Como sugerencia convenida, iniciaremos con un sistema simple que nos permita familiarizarnos con el proceso de control de desplazamientos del piezoeléctrico, la adquisición e interpretación de datos, etc, para luego utilizar esta experiencia en el ataque al problema más fino y complejo (sistemas simples están descritos en: http://www.geocities.com/spm_stm/Project.html, http://www.angelfire.com/electronic2/spm/index.html, http://web.archive.org/web/20021219052018/http:/www.peddie.k12.nj.us/Research/STMProject/, mientras que el sistema objetivo del proyecto está descrito en detalle en: http://sxm4.uni-muenster.de/stm-en/).

En las siguientes ligas hay información valiosa para el proyecto. Leámosla para familiarizarnos con los fenómenos físico-cuánticos responsables y la parte electrónica y mecánica:

- http://www.chembio.uoguelph.ca/educmat/chm729/STMpage/stmtutor.htm (nice stuff...easy for beginners)
- http://www.sas.org/tcs/weeklyIssues_2005/2005-04-22/wanderings/index.html (hey! an 18 years old teenager built a STM –and won a $50,000 USD prize at the 2004 Intel Science & Engineering Fair…so, it has not be so tricky!)
- http://www.lugoj.com/NanotechSTMArticles/HomeBrewSTMs.html (Introduction to Home Brewing an STM!)
- Una tesis de maestría en Física (Texas Tech) sobre el mismo tema: STM (http://www.phys.ttu.edu/~tlmde/thesis/TOC.html) (bueno para ver todos los problemas que tuvo que resolver)
- Hey! You can start your own instrument company! (http://www.mcallister.com/stmpg.html)

Bueno, hasta aquí vamos. Adelante con el proyecto! Próximamente haremos la disección del mismo para repartir responsabilidades (aunque son compartidas por todos).

Uge Treske and his low-cost STM!

Uwe Treske, 18, a senior from Paul Gerhardt Gymnasium in Grafenhainichen, Sachsen Anhalt, Germany, developed an inexpensive but powerful microscope that delivers a 1,000-fold improvement in resolution over normal light microscopes. His physics project is titled "Low-Cost Scanning Tunneling Microscope." Treske was inspired when he saw a German television show about the Scanning Tunneling Microscope (STM),an important tool in nanotechnology. "It fascinated me-the idea that you could achieve atomic resolution. I wanted to see an atom for
myself. Of course, STM are very expensive. I decided to try to make a cheaper version so that any student could work with this tool." Treske based his invention on the principles of the STM, but used inexpensive materials that he acquired in his community of 8,000. For example, he used tungsten filament from ordinary light bulbs to make the fine spike tip for his microscope, recycled styrofoam blocks for building materials, and the standard sound card from a personal
computer for digitizing the measuring signal. Where did his inventiveness come from? "My science career began with my grandfather. He repaired television sets, and I helped him. That taught me about chips and circuit boards," Treske said. "I've learned that you can do scientific research anywhere, with whatever resources are available to you."
