Printable circuits with silver nanowires Scientists at Duke University compared the conductivity of films made from different shapes of silver nanostructures and found that electrons move through films made of silver nanowires much easier than films made from other shapes, like nanospheres or microflakes. In fact, electrons flowed so easily through the nanowire films that they could function... » read more

Antiferromagnetic magnetoelectric RAM Researchers at Helmholtz-Zentrum Dresden-Rossendorf (HZDR), Swiss Nanoscience Institute, and the University of Basel developed a concept for a new, low power memory chip. In particular, the group focused on finding an alternative to MRAM using magnetoelectric antiferromagnets, which are activated by an electrical voltage rather than by a current. "... » read more

Paper-based bacteria battery Researchers at Binghamton University, State University of New York have created a bacteria-powered battery on a single sheet of paper that can power disposable electronics. The manufacturing technique reduces fabrication time and cost, and the design could revolutionize the use of bio-batteries as a power source in remote, dangerous and resource-limited areas. ... » read more

Tiny diamond radio Researchers at Harvard built the world's smallest radio receiver, built out of an assembly of atomic-scale defects in pink diamonds. The radio uses tiny imperfections in diamonds called nitrogen-vacancy (NV) centers. To make NV centers, researchers replace one carbon atom in a diamond crystal with a nitrogen atom and remove a neighboring atom -- creating a system that i... » read more

Stamping with electronic ink Engineers at MIT fabricated a stamp made from carbon nanotubes that is able to print electronic inks onto rigid and flexible surfaces. The team's stamping process should be able to print transistors small enough to control individual pixels in high-resolution displays and touchscreens, said A. John Hart, associate professor of contemporary technology and mecha... » read more

3D porous microsupercapacitors A research team from the King Abdullah University of Science and Technology (KAUST) developed an integrated microsupercapacitor targeted at self-powered system applications where the power source may be intermittent, such as sensors for wearables, security, and structural health monitoring. The key to the microsupercapacitors is vertically-scaled three-dimen... » read more

Perovskites for data storage Scientists at EPFL developed a new perovskite material whose magnetic order can be rapidly changed without disrupting it due to heating that could potentially be used to build next-generation hard drives. "We have essentially discovered the first magnetic photoconductor," said Bálint Náfrádi, a postdoc at EPFL. This new crystal structure combines the advant... » read more

PV technology comparison Joshua J. Romero at the IEEE Spectrum put together an overview of photovoltaic technologies, including the world records for each type of cell, grouped into five broad categories. There is a brief overview of each cell type and some of its trade-offs. He also looks at how fast each technology has made efficiency gains. The most rapid progress is being seen in high... » read more

Increasing lithium battery density Researchers at Columbia University developed a new method to increase the energy density of lithium batteries using a trilayer structure that is stable in ambient air. "When lithium batteries are charged the first time, they lose anywhere from 5-20% energy in that first cycle," said Yuan Yang, assistant professor of materials science and engineering at C... » read more
