Mars Rover Device Gets New Mission on Earth

Developed to sniff out extraterrestrial life on other planets, a portable device known as the Mars Organic Analyzer (MOA) is taking on a new role in detecting air pollutants on Earth.

Researchers in California report the development of a modified MOA able to detect polycyclic aromatic hydrocarbons (PAHs), potentially carcinogenic molecules from cigarette smoke and wood smoke, volcanic ash, and other sources. The report appeared in the Jan. 15 issue of ACS’ semi-monthly journal Analytical Chemistry.

In the report, Richard A. Mathies and colleagues indicate that current earthbound PAH detection focuses on the cleanup of environmental contamination sites. On other planets, the concentration of organic PAH molecules can provide valuable insight into environmental conditions and the potential for extraterrestrial life. But existing PAH detection methods are slow and costly. Scientists thus are seeking an inexpensive, rapid and nondestructive technique for the measurement of PAH contamination.

The researchers tested samples from Lake Erie and a hydrothermal vent from the Gulf of California, as well as a Martian analogue sample from the Mars-like Atacama Desert, one of the driest spots on earth. They found that the detection sensitivity of the device was on par with current laboratory methods. “The method of PAH analysis developed here significantly advances the MOA’s capabilities for organic carbon detection and may also prove useful for environmental monitoring,” says Mathies.

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
