Flow process diagram. (A) An array of bottom-contact gold electrodes on SiO2∕Si and (Top Right) a close-up illustration of the electrode geometry. (B) A self-adsorbed monolayer (SAM) of octadecyltrichlorosilane (OTS) is deposited on SiO2 by immersion into a 1% solution in toluene for 1 h. (C) The treated electrode is immersed in a container with …
How the virus is tackled * 1 Virus (purple) circulating in the bloodstream recognised by antibodies (yellow) of the immune system * 2 Virus attaches to outer cell membrane with antibodies still attached * 3 Virus invades the cell membrane and emerges inside the cell * 4 Remains of cell membrane disappear and the virus …
Two videos about D-Wave and quantum annealing from presentations made on October 22, 2010 Dwave has solved over 12 million Ising problems using their adiabatic quantum computer chips over the past 12 months. They are focused on machine learning applications. They are getting lower generalization error and faster training for binary classifiers for image classication …
A “multilayer micromixer” production process developed at Oregon State University allows a much higher production rate of nanotech particles than conventional approaches, with no loss of quality. (Graphic courtesy of Oregon State University) Engineers at Oregon State University have discovered a new method to speed the production rate of nanoparticles by 500 times, an advance …
Arxiv – Electromagnetic wave analogue of electronic diode (11 page pdf) An electronic diode is a nonlinear semiconductor circuit component that allows conduction of electrical current in one direction only. A component with similar functionality for electromagnetic waves, an electromagnetic isolator, is based on the Faraday effect of the polarization state rotation and is also …
Murdoch University researchers have been able, with the help of added microorganisms, to turn sand into stone rapidly. There was PHd thesis work in 1999-2002 * This bacterium uses an enzyme to make its surroundings less acidic, which is a good environment for them to grow”, said Ms Whiffin. The by-product of this reaction is …
Mike Treder wrote an article called Are we in the future yet ? He laments failed predictions from the 1980s. Mike Treder does not know where or how to look for the “future”. Mike Treder notes several predictions and here is one – Machines will be capable, within twenty years, of doing any work a …
3D printing company Stratasys has teamed with Kor Ecologic to create the first 3D printed car, the Urbee. Recently we covered the Airbus projects to develop super large format 3d printing of Airplane parts and eventually all the parts for whole Airplanes. Stratasys today announced its development partnership with Winnipeg engineering group, Kor Ecologic. The …
Sandstone roads could replace regular asphalt. The resulting roads are 20% more reflective and can reduce the urban heat island effect by 2-3 degrees celsius. The project is a part of the iida awards 2010 competition, organized by designboom in collaboration with incheon (south korea) metropolitan city. UPDATE : The more than ten year history …
Here is the John Gedmark interview by Sander Olson. Mr. Gedmark is the Executive Director of the Commercial Spaceflight Federation, which is dedicated to promoting commercial spaceflight. Recent events indicate that the commercial spaceflight industry may soon reach critical mass and become a self-sustaining industry. Virgin Galactic’s Spaceship Two recently completed its second glide flight, …
