Electronics and Photonics
A new study shows how harnessing the quantum properties of light can create a transmission technology impervious to eavesdropping.
Imagine communicating with your bank, the IRS or your doctor by way of an Internet that was perfectly secure. Your most private data would be protected with absolute certainty and, better yet, if any bad actor were to try to eavesdrop you would know immediately. Such is the promise of secure quantum communication.

Stanford researchers have invented a lithium-ion battery that turns on and off depending on the temperature. The new technology could prevent battery fires that have plagued laptops, hoverboards and other electronic devices.
Stanford researchers have developed the first lithium-ion battery that shuts down before overheating, then restarts immediately when the temperature cools.

Stanford-led skyscraper-style chip design could boost electronic performance by factor of a thousand
In modern computer systems, processor and memory chips are laid out like single-story structures in a suburb. But suburban layouts waste time and energy. A new skyscraper-like design, based on materials more advanced than silicon, provides the next computing platform.
For decades, engineers have designed computer systems with processors and memory chips laid out like single-story structures in a suburb. Wires connect these chips like streets, carrying digital traffic between the processors that compute data and the memory chips that store it.
But suburban-style layouts create long commutes and regular traffic jams in electronic circuits, wasting time and energy.

Only an atom thick, graphene is a key ingredient in three Stanford projects to create data storage technologies that use nanomaterials other than standard silicon.
The memory chips in phones, laptops and other electronic devices need to be small, fast and draw as little power as possible. For years, silicon chips have delivered on that promise.
But to dramatically extend the battery life of mobile gadgets, and to create data centers that use far less energy, engineers are developing memory chips based on new nanomaterials with capabilities that silicon can't match.

Stanford scientists and an international research group receive funding to advance solar cells, batteries, renewable fuels and bioenergy.
The Global Climate and Energy Project (GCEP) at Stanford University has awarded $10.5 million for seven research projects designed to advance a broad range of renewable energy technologies. The funding will be shared by six Stanford research teams and an international group from the United States and Europe.

Engineers at Stanford have developed a prototype single-fiber endoscope that improves the resolution of these much-sought-after instruments fourfold over existing designs. The advance could lead to an era of needle-thin, minimally invasive endoscopes able to view features out of reach of today’s instruments.
Engineers at Stanford have demonstrated a high-resolution endoscope that is as thin as a human hair with a resolution four times better than previous devices of similar design. The so-called micro-endoscope is a significant step forward in high-resolution, minimally invasive bio-imaging with potential applications in research and clinical practice. Micro-endoscopy could enable new methods in diverse fields ranging from study of the brain to early cancer detection.

Decal-like application process allows thin, flexible solar panels to be applied to virtually any surface from business cards to roofs to window panes.
For all their promise, solar cells have frustrated scientists in one crucial regard – most are rigid. They must be deployed in stiff and often heavy fixed panels, limiting their applications. So researchers have been trying to get photovoltaics to loosen up. The ideal: flexible, decal-like solar panels that can be peeled off like band-aids and stuck to virtually any surface, from papers to window panes.

Professor of Electrical Engineering will develop new reflective coatings to help cool buildings and cars.
Shanhui Fan, a professor of electrical engineering at the Stanford School of Engineering, has been chosen to receive $399,901 to develop Photonic Radiative Day-Time Cooling Devices, better imagined as coatings for the rooftops of buildings and cars that reflect sunlight, allowing heat to escape and enabling passive cooling, even when the sun is shining. Fan’s device would require no electricity and would reduce the need for air conditioning, leading to energy and cost savings.
