Materials in Focus
| Bandgap engineering in graphene nanoribbons sets the stage for next-generation electronic devices |
 |
Miniaturization of consumer electronics has put pressure on the industry to develop semiconductor devices that operate at smaller length scales. Graphene-based electronics have the potential to outshine current technology with greater scalability, more control over dopants, and higher charge-carrier mobility. Graphene-based electronics would benefit from ballistic electron transport; much like a carefully aimed shot will arrive at its target in the shortest possible time, the scattering of electrons from atomic sites is limited in materials on very small length scales. With the electrons experiencing minimal obstruction, these devices could operate at much faster speeds, leading to improved performance. |
Microfluidic nozzle for 3D printing switches between two viscoelastic inks on the fly |
 |
Direct ink writing is a type of extrusion-based three-dimensional (3D) printing method that has a wide range of applications, from printing vascularized tissues to wearable sensors to micro-batteries. For the past decade or so, however, the technique has largely been limited to printing objects composed of a single-material. A Harvard University team led by materials scientist Jennifer Lewis has now designed a new microfluidic printhead, or nozzle, that is able to seamlessly switch between printing two different viscoelastic materials during the fabrication process. |
Artificial muscles from gold-plated onion cells bend and elongate simultaneously |
 |
In recent years, scientists have made much progress with the development of artificial muscles. But the micro-actuators made to date have all lacked the ability to simultaneously bend and contract or elongate. A team led by engineers Pei-Zen Chang and Wen-Pin Shih of the National Taiwan University (NTU) has now created such an artificial muscle from an unlikely material: onion epidermal cells.The cheap, environmentally friendly artificial muscles could have numerous potential applications in the future, including in biomedicine and robotics. |
GaAs thin film electronics made easy by laser liftoffs |
 |
Though considerably more expensive than their silicon counterparts, gallium arsenide (GaAs)-based electronic devices have seen a resurgence in recent years. GaAs devices have many advantages, not the least of which is faster processing power. The high cost of wafers and the fact that they often cannot be reused multiple times, however, has prohibited production of GaAs devices on a large scale. A study published in MRS Communications introduces a laser liftoff method to fabricate GaAs devices which does not sacrifice the wafer, drastically cutting the cost. |
Industry Focus
GaN power transistors priced cheaper than silicon
El Segundo, Calif.-based Efficient Power Conversion, announced that it is offering two types of power transistors made from gallium nitride that it has priced cheaper than their silicon counterparts. “Gallium nitride has taken the torch and is now running with it,” CEO Alex Lidow says.
Three-dimensional printed human skin is L’Oreal’s next big thing, and it’s not creepy at all
Bioprinted human skin has been on the scene for some time, but L’Oreal—yes, the cosmetics company—is hoping to get into the game. It is partnering with Organovo, a 3-D human tissue company, to print tons of the stuff to facilitate animal-free cosmetics testing.
Policy Focus
Materials science buoyed by education policy in Ethiopia
To accommodate Ethiopia’s major population shift from rural to urban areas, the country’s Ministry of Finance and Economic Development (MOFED) authored a countrywide strategic document known as the Growth and Transformation Plan (GTP I). During the course of implementing the plan, the government has not just supported materials science programs, it has also birthed them.
Pentagon to analyze grantsmaking process for gender bias
The Department of Defense (DoD) will start collecting data on the gender of its grant applicants and award recipients to help determine whether women in science and engineering face any discrimination in the grantsmaking process.

The 15 moonshot technologies NASA is funding to make science fiction a reality
Each year, the NASA Innovative Advanced Concepts program awards funding to a set of research projects on the bleeding edge of technology. These aren’t your everyday “disruptive” apps and social networks; we’re talking interstellar exploration, nanotube comet sensors, and robot squids. More.
Dutch solar road makes enough energy to power household
Engineers in the Netherlands say a novel solar road surface that generates electricity and can be driven over has proved more successful than expected. In the first six months since it was installed, the panels beneath the road have generated over 3,000 kwh. This is enough to provide a single-person household with electricity for a year. More.
Podcast: The Post-Billiards Age
A hundred years ago, there were 830 pool halls in the city of Chicago. Today, there are ten. Billiards is not what it used to be—but we continue to live in a world affected by its former prominence. The growth of billiards led to the development of a material that would come to define the modern world. More.

NEW PRODUCTS FOCUS
| High Performance Air Condenser |
|
The Asynt CondenSyn is a new high performance air condenser for synthetic chemistry experiments that requires no cooling water for operation. The robust design uses a borosilicate glass manufacturing technique and this, together with a proprietary multiple hyperbolic profile, ensures optimum heat removal as vapors pass along its length. CondenSyn additionally incorporates a non-roll feature to help prevent accidents if left on a lab bench. And by not using water as the condensing coolant, CondenSyn eliminates the environmental and running costs associated with the need for constant running tap water as well as potential issues associated with water leakage.

| Nanomechanical Test Stage |
|
ZEISS announces the new Ultra Load Stage for ZEISS Xradia Ultra 3D X-ray microscopes (XRM). Xradia Ultra Load Stage uniquely enables in situ nanomechanical testing—compression, tension, indentation—with non-destructive 3D tomographic imaging. For the first time, researchers will be able to image the evolution of structure in 3D under load down to 50 nm resolution. This new capability applies to a wide range of interests, covering both engineered and natural materials.
