Solar Cells From A Paintbrush To fabricate solar cells, engineers may someday trade their clean rooms for a paint smock. Researchers have developed a paste of semiconducting nanoparticles called solar paint that could lead to cheaper and easier-to-produce solar cells (ACS Nano, DOI: 10.1021/nn204381g). Many researchers working on solar energy have focused on improving the efficiency of silicon-based solar cells. But silicon devices have a high price tag because of the specialized protocols and equipment needed, says Prashant Kamat of the University of Notre Dame. He points out that some researchers have avoided using silicon and created cells using quantum dots made from materials like lead sulfide. Unfortunately, the fabrication process for these quantum dot solar cells is still expensive and slow.

Two Diamonds Linked by Strange Quantum Entanglement Scientists have linked two diamonds in a mysterious process called entanglement that is normally only seen on the quantum scale. Entanglement is so weird that Einstein dubbed it "spooky action at a distance." It's a strange effect where one object gets connected to another so that even if they are separated by large distances, an action performed on one will affect the other. Entanglement usually occurs with subatomic particles, and was predicted by the theory of quantum mechanics, which governs the realm of the very small.

SolarSinter : markus kayser Solar Sinter 2011 In August 2010 I took my first solar machine - the Sun-Cutter - to the Egyptian desert in a suitcase. This was a solar-powered, semi-automated low-tech laser cutter, that used the power of the sun to drive it and directly harnessed its rays through a glass ball lens to ‘laser’ cut 2D components using a cam-guided system. The Sun-Cutter produced components in thin plywood with an aesthetic quality that was a curious hybrid of machine-made and “nature craft” due to the crudeness of its mechanism and cutting beam optics, alongside variations in solar intensity due to weather fluctuations. holistic education @ the encyclopedia of informal education A brief introduction to holistic education. What is holistic education? What are the primary philosophies that distinguish it from traditional education? Who were the pioneers in holistic education?

Fractal Patterns Seen in Semiconductor Magnetism : Fractal patterns have been observed for the first time at the quantum scale, and the implications – and applications – may be huge. Image: Roushan/Yazdani Research Group Mathematicians and physicists have known for some time that the equations that govern the magnetic phase-transition of metals will produce fractal patterns when iterated in a computer. But until now, nobody had ever seen actual fractal patterns at the nanoscale before. New school system in Sweden is eliminating classrooms entirely Telefonplan School, in Stockholm Sweden has new school system that is eliminating all of its classrooms in favor of an environment that fosters children’s “curiosity and creativity.” (Pics) Vittra, which runs 30 schools in Sweden, wanted learning to take place everywhere in its schools — so it threw out the “old-school” thinking of straight desks in a line in a four-walled classroom (via GOOD).

Time and Quantum Physics relationships to Phi The Golden Ratio seems to be appearing in several places in the Quantum Physics Model. Because an electron has an electric charge and an intrinsic rotational motion, or spin, it behaves in some respects like a small bar magnet and is said to have a magnetic moment. Because the electron also has mass, it behaves in some respects like a spinning top, and is said to have spin angular momentum. The g factor of the electron is defined as the ratio of its magnetic moment to its spin angular momentum. The electron g-factor is due to the stretching of space-time as the electron spins at the speed of light.

Classrooms Traditionally, classrooms have tables, chairs, a board at one end, they all share a similar layout. But, how effective is this? When I was teaching in a school, quite often we moved the tables aside and just used chairs, or sometimes sat on the floor. Golden ratio discovered in quantum world: Hidden symmetry observed for the first time in solid state matter Researchers from the Helmholtz-Zentrum Berlin für Materialien und Energie (HZB), in cooperation with colleagues from Oxford and Bristol Universities, as well as the Rutherford Appleton Laboratory, UK, have for the first time observed a nanoscale symmetry hidden in solid state matter. They have measured the signatures of a symmetry showing the same attributes as the golden ratio famous from art and architecture. The research team is publishing these findings in the Jan. 8, 2010 issue of the journal Science. On the atomic scale particles do not behave as we know it in the macro-atomic world. New properties emerge which are the result of an effect known as the Heisenberg's Uncertainty Principle.
