Carnival of Nuclear Energy 189

The Carnival of Nuclear Energy 189 is up at Atomic Power Review Canadian Energy issues – Reducing carbon pollution from electric power generation: What works? In the nearly 17 years since the Kyoto Protocol, many countries, especially Germany, have embarked on major efforts to reduce their national carbon footprints. How have those efforts paid off? …

Bio-inspired way to grow graphene for electronic devices has potential for batch fabrication with large-scale integrated circuits on silicon wafers

Singapore researchers came up with the one-step method to grow and transfer high-quality graphene on silicon and other stiff substrates. This promises the use of graphene in high-value areas where no technique currently exists to grow and transfer graphene with minimal defects for use in semiconductors. Prof Loh, who is also a Principal Investigator with …

Xenon ion and water cubesat engines for interplanetary cubesats with costs ten thousand times less

Benjamin Longmier, Michigan University, is developing the CubeSat Ambipolar Thruster (CAT), a new rocket propulsion system powered by the Sun and propelled by water, which will push small spacecraft like CubeSats around and far beyond the Earth. They received a $200,000 private donation and have raised over $96,000 on Kickstarter. What can be enabled with …

Carnival of Space 334

The Carnival of Space 334 is up at Urban Astronomer Universe Today – For the past five years, I’ve been constructing this list of all things astronomical for the coming year, lovingly distilling the events transpiring worldwide down to a 101 “best events of the year”. A Triple transit of three of Jupiter’s moons on …

Details of the performance, capabilties, physics and scaling of the state of the art in superconducting circuits for quantum computers

Superconducting Circuits for Quantum Information: An Outlook – The performance of superconducting qubits has improved by several orders of magnitude in the past decade. These circuits benefit from the robustness of superconductivity and the Josephson effect, and at present they have not encountered any hard physical limits. However, building an error-corrected information processor with many …

Dwave Systems Interviews about their Quantum Computer, Continuing Controversy and a competitor with a 20 qubit system and a million qubit design based on trapped ions

The scientific community accepts two models for building qubits and keeping them in quantum states—gate and adiabatic. D-Wave’s is adiabatic, and so is the 20-qubit model Christopher Monroe, the Bice Zorn Professor of Physics at the University of Maryland and fellow of the Joint Quantum Institute, has in his lab. Adiabatic quantum computers apply quantum …

2014 could be the year of the fast neutron nuclear reactor with the Russia 800 MWe Beloyarsk 4 and the Indian 470 MWe Kalpakkam set to start

Commissioning is about to start at Russia’s forthcoming fast reactor, Beloyarsk 4. After a lengthy construction period, engineers are preparing for criticality in April 2014. The unit will be a 789 MWe fast-neutron reactor of the BN-800 design, fuelled by a mix of uranium and plutonium oxides arranged to produce new fuel material as it …
