Can Graphene Be Mass Manufactured?

By Katherine Derbyshire - 18 Oct, 2018 - Comments: 3

Since the isolation of graphene in 2004, the high mobility and unique transport properties of 2-dimensional semiconductors have tantalized physicists and materials scientists. Their in-plane carrier transport and lack of dangling bonds potentially can minimize line/edge scattering and other effects of extreme scaling. While 2-D materials cannot compete with silicon at current device dime... » read more

Single-atom storage Scientists at EPFL are working on a single-atom magnetic data storage device that takes advantage of quantum effects to provide dense storage. The team is using holmium, an element they've been exploring for years. "Single-atom magnets offer an interesting perspective because quantum mechanics may offer shortcuts across their stability barriers that we could exploit in t... » read more

New quantum electronic material has atomic structure resembling a Japanese basketweaving pattern According to MIT, Harvard University, and Lawrence Berkeley National Laboratory researchers, a motif of Japanese basketweaving known as the kagome pattern has preoccupied physicists for decades. They reminded that kagome baskets are typically made from strips of bamboo woven into a highly symmetric... » read more

Lithium-iron-oxide battery Scientists at Northwestern University and Argonne National Laboratory developed a rechargeable lithium-iron-oxide battery that can cycle more lithium ions than its common lithium-cobalt-oxide counterpart, leading to a much higher capacity. For their battery, the team not only replaced cobalt with iron, but forced oxygen to participate in the reaction process as we... » read more

Greener greenhouses Researchers at the University of California, Santa Cruz are testing greenhouses capable of generating some of their own energy, without hampering plant growth. Greenhouses use electricity to control temperature and power fans, lights, and other monitoring systems. Electricity-generating solar greenhouses utilize Wavelength-Selective Photovoltaic Systems (WSPVs), a novel ... » read more

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

Photonics Moves Closer To Chip

By Ed Sperling - 20 Jun, 2016 - Comments: 0

Silicon photonics is resurfacing after more than a decade in the shadows, driven by demands to move larger quantities of data faster, using extremely low power and with minimal heat. Until recently, much of the attention in photonics focused on moving data between servers and storage. Now there is growing interest at the PCB level and in heterogeneous multi-chip packages. Government, academi... » read more
