Apple and Q-Dots.
While we know that Apple’s next display shift will be to OLED for their 2017 Anniversary edition iPhone, Apple is always looking to the next wave technology just on the horizon. So what’s beyond OLED? At the moment, many think the next trend points to Quantum Dot LED or QDLED. While the structure of a QLED is very similar to OLED technology, the difference is that the light emitting centers are cadmium selenide nanocrystals, or quantum dots. Theoretically, the advantages to this type of display is that it could reportedly deliver brighter ‘pure color’ and consumes less power, in fact close to 50% less power. The technology is also ideal for consumer devices that demand a flexible display. When Apple first introduced their vision of an Apple Watch in 2013, they presented it with a ‘continuous’ display that completely wraps around a users wrist as noted in the patent figure below. A QDLED type of display would allow such a form factor to come to market.
While Quantum Dot based displays are no doubt many years out, Apple is already on record having explored the technology in a string of four patent filings that we covered back in 2014 in a report titled “Quantum Dots Could Take the Retina Display to the Next Level.” Today, another Quantum Dot invention came to light.
Nice.
Elite endurance athletes could be able to keep going for longer thanks to a new drink developed to give soldiers extra energy in battle, a study using former Olympians has found.
Scientists found that cyclists using the drink, which temporarily switches the body’s energy source from glucose to ketones, could travel an extra quarter of a mile than those taking a different energy supplement.
The idea of developing the ketone drink came from the US Army’s research branch, DARPA, who invited scientists to create the most energy efficient food that soldiers could take onto the battlefield.
Computers use switches to perform calculations. A complex film with “quantum wells”—regions that allow electron motion in only two dimensions—can be used to make efficient switches for high-speed computers. For the first time, this oxide film exhibited a phenomenon, called resonant tunneling, in which electrons move between quantum wells at a specific voltage. This behavior allowed an extremely large ratio (about 100,000:1) between two states, which can be used in an electronic device as an ON/OFF switch to perform mathematical calculations (Nature Communications, “Resonant tunneling in a quantum oxide superlattice”).
Efficient control of electron motion can be used to reduce the power requirements of computers. “Quantum wells” (QW) are regions that allow electron motion in only two dimensions. The lines (bottom) in the schematic show the probability of finding electrons in the structure. The structure is a complex oxide (top) with columns (stacked blue dots corresponding to an added element) where the electrons are free to move in only two dimensions. This is a special type of quantum well called a two-dimensional electron gas (2DEG). (Image: Ho Nyung Lee, Oak Ridge National Laboratory)
To meet our exponentially growing need for computing power without a corresponding jump in energy use, scientists need more efficient electronic versions of switches to perform calculations. Efficient switches need materials that switch between well-defined ON/OFF states. The results of this study could lead to a new class of energy-efficient electronics because these materials can ensure the electronic switches are ON or OFF. These electronic switches could lower power consumption in electronics enabling, for example, the development of high-speed supercomputers and cell phones with longer battery life.

Long-term human colonization of Mars is feasible, as long as Red Planet pioneers “live off the land,” a recent NASA report concludes.
“There are massive resources on Mars obtainable from the atmosphere and extracted from the regolith which are capable of supporting human colonization,” write the authors of the report, which is called “Frontier In-Situ Resource Utilization for Enabling Sustained Human Presence on Mars.”
Using Martian resources, existing technologies could supply water, oxygen, fuel and building materials, the report adds, “to relax the dependence on Earth during the buildup of a colony on Mars.” [Red Planet or Bust: 5 Crewed Mars Mission Ideas].
If you’ve seen the dystopian nightmare fuel that is BBC’s Black Mirror, you might be getting the “No no nos” about Sony’s latest patent application — ‘smart’ contact lenses with a built-in camera that can record, play, and even store videos right before your eyes.
With Google and Samsung having already filed patents for contact lenses with tiny, built-in cameras, these things seem inevitable, and they have the potential to change everything about the way we interact with each other… for better or worse.
So yep, that means in the future we could all be playing back recordings of old conversations to our friends and family to win an argument, or, you know, watching a ‘greatest hits’ compilation while having sex with our significant other. But we have more faith in the good of mankind than that, right?
Dirty water has a use.
New technology doesn’t always look great, but researchers at Binghamton University are aiming to prove that function and style don’t have to be at odds with a new bacteria-powered battery that takes its design cues from origami.
Seokheun “Sean” Choi, an assistant professor of computer and electrical engineering at Binghamton, and two of his students recently published in the journal Biosensors and Bioelectronics a report on their invention of a microbial fuel cell that runs on nothing more than the bacteria found in just a few drops of dirty water.
