Recent quantum dots are three times better than thermoelectric devices from the mid-1990’s. There are quantum wells that get 4.5ZT. Vehicle efficiency technology gets about 176 million per year The new thermoelectronics are not magic technology. They are part of one of the highest value US government research programs. The advanced versions should be ready …
Higher speed communication between parts of a telescope and to scientists enables larger telescopes because “more pixels generate more data, and you have to have way to move more data around.” The boost in speed makes information processing faster among the James Webb Space Telescope’s (JWST) four science instruments as they “talk” to each other …
Two teams have independently succeeded in placing a cloud of chilled rubidium atoms within an optical cavity, which traps light between two opposed mirrors. The combination could one day form a quantum memory element. Colombe, Jakob Reichel and colleagues have put a BEC between two mirrors, which form an optical cavity trapping photons of a …
Submarines could be made less visible to sonar using metamaterials There are still many challenges to overcome including the variability of the surrounding water and enabling lack of sonar reflection from more than one direction (ie another submarine at the same depth unable to detect but one above or below could) Brian WangBrian Wang is …
A Melbourne PhD student has developed technology to make broadband internet up to 200 times faster without having to install expensive fibre optic cables. Harnessing the potential power of telephone lines and DSL broadband, the technology will deliver internet speeds up to 250 megabits per second, compared with current typical speeds of between one and …
Researchers at the Advanced Technology Institute of the University of Surrey, in collaboration with researchers from China and the USA, have demonstrated a 100-fold increase in the light emission from a nylon polymer sample, by incorporating multi-walled carbon nanotubes (MWCNT). Previously adding carbon nanotubes (CNT) reduces the light emission from the composite, due to quenching …
Known by its lab name of RTS,S the prototype is raising high hopes of the first vaccine shield against a disease that claims more than a million lives a year — 800,000 of them African children aged under five — and sickens hundreds of millions more. Infants who received RTS,S were 65 percent less at …
Molecular Imprints Inc. (MII) claims that Toshiba Corp. has ”validated” the use of its nano-imprint lithography technology in developing 22-nm CMOS devices Nanoimprint seems to be a viable plan B in case EUV stumbles. It’s unclear if Toshiba will put nano-imprint tools into its production fabs at 22-nm and beyond. At this node, Toshiba is …
The Wall Street Journal discusses the activity of companies trying to get nuclear plants certified and built. Before seeking the combined construction permit and operating license, the NRC wanted utilities to first seek approval for their proposed plant sites, to determine their suitability. That, the commission said, would speed up the process of going through …
Allan Greenleaf, professor of mathematics at the University of Rochester, and his coauthors lay out the possibility of building a sort of invisible tunnel between two points in space. Invisible tunnel Current technology can create objects invisible only to microwave radiation, but the mathematical theory allows for the wormhole effect for electromagnetic waves of all …
Mitochondria play an unexpectedly important role in cell survival in the face of stress, according to a paper in this week’s Cell. The authors suggest that this cell stress response may provide clues about how calorie restriction extends lifespan in mammals. This research also confirms one of the seven parts of the SENS strategy for …
