Ink FETs The University of Pennsylvania has developed a new way to make chips by using nanocrystal inks. The devices, dubbed nanocrystal field-effect transistors (FETs), could be used one day to develop chips for flexible and wearable applications In the lab, researchers devised spherical nanoscale particles. These particles, which have electrical characteristics, were dispersed in a liquid... » read more

Wrapping silver nanowires While they hold promise for applications including flexible displays and solar cells, silver nanowires are also susceptible to damage from highly energetic UV radiation and harsh environmental conditions has limited their commercialization, according to Purdue University researchers. However, new research suggests wrapping the nanowires with an ultrathin layer of c... » read more

Massless particles for faster electronics Princeton University researchers along with an international team have finally proved a massless particle that had been theorized for 85 years. They say this particle could give rise to faster and more efficient electronics because of its unusual ability to behave as matter and antimatter inside a crystal.

A viable silicon substitute A new study by UC Berkeley, the University of Pennsylvania and the University of Illinois at Urbana-Champaign (UIUC) moves graphene a step closer to knocking silicon off as the dominant workhorse of the electronics industry. They reminded that while silicon is ubiquitous in semiconductors and integrated circuits, researchers have been eyeing graphene, a one-atom... » read more

Phase transitions between liquid, gas Researchers from the University of Tokyo and Tokyo Institute of Technology reminded that materials change their form between three states -- solid, liquid, and gas -- depending on factors such as temperature and pressure. However, a phase transition does not necessarily occur between liquid and gas, and they can continuously transform from the one to the o... » read more

All graphene is not the same Widely touted as the most electrically conductive material ever studied, researchers at the University of Pennsylvania now understand that all graphene is not the same. With so few atoms comprising the entirety of the material, the arrangement of each one has an impact on its overall function. The team has used an advanced microscope to study the relationship be... » read more

Tagging is a way of organizing information and today’s System Bits looks at two aspects of tagging. The first is an algorithm associated with social media and the second about how the brain geotags information. New Algorithm Finds You, Even in Untagged Photos You cannot hide on the Internet anymore. Anything posted online can be found, although in the past photos that were untagged may ha... » read more

Knife-Wielding Robot Cornell University has taught a knife-wielding robot to work in a mock-supermarket checkout line. In doing so, researchers have modified a Baxter robot from Rethink Robotics. In the experiment, the robot coactively learns and makes adjustments while an action is in progress. But when performing tasks at a checkout line, the robot’s problem is to identify the appropria... » read more

Harvesting energy from light In a finding they believe could improve technologies for generating electricity from solar energy and lead to more efficient optoelectronic devices used in communications, researchers from the University of Pennsylvania and Duke University have demonstrated a new mechanism for extracting energy from light. They said the process is much more efficient than conven... » read more
