Stephen Chu (energy secretary) sounded an alarm with Is the Energy Race our new “Sputnik” Moment? (30 page presentation) For over a century, America has led the world in innovation. Today, that leadership is at risk. In the last 15 years, Chu said, China has gone from 15th place to 5th in international patents and …
The Carnival of Space 179 is up at Weird Sciences This site provided : What was the best way to use the Saturn V to reach the moon in retrospect ? Lunar Surface Rendezvous and other methods would have enabled 3 times more payload to be landed on the moon and if what was landed …
Here is the Eugenio Culurciello interview. Dr. Culurciello is an associate professor of engineering at Yale University. Dr. Culurviello has developed a low power FPGA chip that is specifically designed for robotic vision. The aim of Dr. Culurciello’s research is to create a robotic vision system that is equivalent to human vision. The system should …
Arxiv – Enhancement of the zero phonon line emission from a single NV-center in a nanodiamond via coupling to a photonic crystal cavity Using a nanomanipulation technique a nanodiamond with a single nitrogen vacancy center is placed directly on the surface of a gallium phosphide photonic crystal cavity. A Purcell-enhancement of the fluorescence emission at …
1. Carey King at the University of Texas at Austin tries to make a case that is common at Peak Oil websites – lower energy return on fossil fuels causes economic recessions. The worst recessions of the last 65 years were preceded by declines in energy quality for oil, natural gas, and coal. Energy quality …
A spray solution of a patient’s own stem cells is healing their severe burns. So far, early experiments under a University of Utah pilot project are showing some remarkable results. What was once a serious burn on Kaye Adkins foot is healing nicely now because of a topical spray. With diabetes as a complication, the …
Taiwan has fabricated n-type conducting UNCD films by Li-doping at very low temperature of about 570°C by simply using a Li-based substrate material. There is no need to use any heater that usually used for diamond growth processes. Applied Physics Letters – Monolithic n-type conductivity on low temperature grown freestanding ultrananocrystalline diamond films We report …
1. Officials in North Korea have warned that they are on the brink of war with the South, as the United States and South Korea prepare to conduct a joint training exercise in the Yellow Sea. North Korea also conducted artillery test fires audible on Yeonpyeong. The rounds fired on Friday were the first heard …
OSRAM’S UX:3 Chip in a new package is 50 percent brighter than the precursor package. High power LED applications like automotive headlights, general lighting, or pocket projectors demand ever increasing brightness. High driving currents yield high brightness, but as the current rises, the efficiency of the LED declines. Hence high efficiency at high currents is …
Scientists have turned photons, the wave/particles we see as light, into one huge super-particle. The photons share the same energy level and can’t be distinguished from each other. Nature – Bose–Einstein condensation of photons in an optical microcavity Bose–Einstein condensation (BEC)—the macroscopic ground-state accumulation of particles with integer spin (bosons) at low temperature and high …
The Brookings Institute had an opinion piece which suggested cutting deals to get China’s support in curbing North Korea. *The only real hope of getting North Korea to relinquish its nuclear weapons is to apply such significant economic pressure that the regime is forced to make a choice between economic collapse and the verifiable dismantling …
