Wireless power transfer technology for high capacity transit

Posted: 12 Feb 2013 06:01 PM PST

Scientists have developed a wireless power transfer technology that can be applied to high capacity transportation systems such as railways, harbor freight, and airport transportation and logistics. The technology supplies 60 kHz and 180 kW of power remotely to transport vehicles at a stable, constant rate.

Large scale production of Edge-Functionalized Graphene Nanoplatelets (EFGnPs)

Posted: 12 Feb 2013 06:00 PM PST

Researchers have pioneered a simple, but efficient and eco-friendly way to produce Edge-selectively functionalized graphene nanoplatelets (EFGnPs) by dry ball milling graphite in the presence of various gases.

Security: Explosive breakthrough in research on molecular recognition

Posted: 12 Feb 2013 12:46 PM PST

Ever wonder how sometimes people still get through security with explosives on their person? Research has revealed a new way to better detect molecules associated with explosive mixtures.

Building a biochemistry lab on a chip

Posted: 12 Feb 2013 10:20 AM PST

Miniaturized laboratory-on-chip systems promise rapid, sensitive, and multiplexed detection of biological samples for medical diagnostics, drug discovery, and high-throughput screening. Using micro-fabrication techniques and incorporating a unique design of transistor-based heating, researchers are further advancing the use of silicon transistor and electronics into chemistry and biology for point-of-care diagnostics.

Precision of GPS in cities improved by 90 percent

Posted: 12 Feb 2013 09:18 AM PST

Researchers have developed a new system which improves the ability of a GPS to determine a vehicle's position as compared to that of conventional GPS devices by up to 90 percent, and which can be installed in any vehicle at a very low cost.

Cheap, strong lithium-ion battery developed

Posted: 12 Feb 2013 08:20 AM PST

Researchers have developed a new lithium-ion battery design that uses porous silicon nanoparticles in place of the traditional graphite anodes to provide superior performance.

Model aims to help companies make products we actually want

Posted: 12 Feb 2013 08:19 AM PST

Researchers have developed a model that will, hopefully, help companies develop innovative products that people actually want to use. The model is a first step towards capturing the behavior of both companies and consumers, so that we end up with more iPods and fewer Edsels.

New world record efficiency for thin film silicon solar cells

Posted: 12 Feb 2013 08:19 AM PST

Researchers have reached a remarkable 10.7 percent efficiency single-junction microcrystalline silicon solar cell, clearly surpassing the previous world record of 10.1 percent held by the Japanese company Kaneka Corporation since 1998. Such significant efficiency, independently certified, was achieved with less than two micrometers of photovoltaic active material – 100 times less than with standard techniques.

Crew rotation and passenger connections spread flight delays, study finds

Posted: 12 Feb 2013 08:19 AM PST

Researchers say that crew rotation and passengers connections systematically spread flight delays due to a domino effect. The work, that proposes a new methodology to assess the degree of air traffic congestion.

Carbon sponge could soak up coal emissions

Posted: 12 Feb 2013 07:06 AM PST

Emissions from coal power stations could be drastically reduced by a new, energy-efficient material that adsorbs large amounts of carbon dioxide, then releases it when exposed to sunlight.

A new 'virtual moderator' helps reach consensus in troubled negotiations

Posted: 12 Feb 2013 07:05 AM PST

Researchers have designed a new fuzzy ontology-based system to help making decisions in our daily lives.

Biological connections in microelectronics

Posted: 12 Feb 2013 07:04 AM PST

Miniaturization of electronic components is reaching a physical limit. While the solution of three dimensional assembly has the advantage of reducing bulk, the manufacture of electrical connections in these new products remains a technological challenge. Biologists and physicists have developed a system of self-assembled connections using actin filaments for 3-D microelectronic structures. Once the actin filaments become conductors, they join the various components of a system together.

'Near-miss' asteroid tracked

Posted: 12 Feb 2013 07:04 AM PST

An asteroid the size of a small office block is due to pass by Earth on Friday 15 February in one of the closest 'near-misses' in recent history. Although there is no chance of the asteroid hitting Earth, the huge rock is being closely monitored by astronomers, as part of an on-going program to monitor 'Near Earth Objects' (NEO).

New material promises better solar cells

Posted: 12 Feb 2013 04:52 AM PST

Researchers have shown that a recently discovered class of materials can be used to create a new kind of solar cell.

Invisible tool enables new quantum experiments

Posted: 11 Feb 2013 08:10 AM PST

Physicists have now succeeded in constructing a novel matter wave interferometer which enables new quantum studies with a broad class of particles, including atoms, molecules and nanoparticles. These lumps of matter are exposed to three pulsed laser light gratings which are invisible to the human eye, exist only for a billionth of a second and never simultaneously.
