Researchers at Sandia National Laboratories’ Combustion Research Facility are helping to develop sparkplug-free engines that will help meet ambitious automotive fuel economy targets of 54.5 miles per gallon by 2025.

They are working on low-temperature gasoline combustion (LTGC) operating strategies for affordable, high-efficiency engines that will meet stringent air-quality standards.

Sandia researchers Isaac Ekoto and Benjamin Wolk said the goal of the LTGC project is an engine in which chemically controlled ignition initiates the combustion of dilute charge mixtures.

Although this article came out in April; I wanted to share because it highlights even how energy companies are using 3D printers.

Shell is using 3D printing technology to make the design and construction of equipment used in oil and gas production faster and more efficient.

The printing technology allows the oil giant to create accurate scale prototypes in material like plastic, which it tests and uses to improve designs and construction process.

The next version of the Bluetooth standard is called Bluetooth 5, and will be formally announced next week, Bluetooth Special Interest Group executive director Mark Powell has revealed. Bluetooth 5 is expected to be a significant upgrade over the current version of the wireless standard, offering double the range and four times the speed of current low-energy Bluetooth transmissions, but the Bluetooth SIG says it will also offer much more support for connectionless services — things like beacons that can help people navigate inside buildings or out in the open.

The roadmap for the next version of Bluetooth was sketched out last year, but the SIG — which has tech giants like Apple, Intel, and Microsoft as backers — will officially lift the lid on Bluetooth 5 on June 16th in London. The group explains that it chose the name to simplify its marketing and make the wireless standard easier to understand for users. That change should be beneficial as our homes get smarter and more connected, with many Internet-of-Things devices relying on Bluetooth to connect to your control devices, and each other.

Seokheun “Sean” Choi, assistant professor of computer and electrical engineering at Binghamton University, along with two of his students, developed the device, a microbial fuel cell that runs on the bacteria available in a few drops of dirty water. They report on their invention in a new paper published online in the journal Biosensors and Bioelectronics (“A disposable power source in resource-limited environments: A paper-based biobattery generating electricity from wastewater”).

A new disposable battery that folds like an origami ninja star could power biosensors and other small devices for use in challenging field conditions.

Airbus introduces the aviation world to a mini-plane called THOR (Test of High-tech Objectives in Reality). It is the first aircraft to be produced using 3D printing technology.

Airbus, a leading aircraft manufacturer, has just unleashed THOR—Test of High-tech Objectives in Reality—a miniature aircraft constructed from 3D printing technology. The windowless, pilotless, and propeller-driven THOR weighs in at 21 kg, and measures less than 4 m long.

Though it is much smaller than a regular jet, THOR is capable of stable flight and even promises to save on time, fuel and money.

A new system for making liquid fuel from sunlight, water, and air is a promising step for solar fuels.

More energy efficient, high performance microprocessors on the way.

Abstract: Tiny high-performance lasers grown directly on silicon wafers solve a decades-old semiconductor industry challenge that, until now, has held back the integration of photonics with electronics on the silicon platform,

A group of scientists from Hong Kong University of Science and Technology; the University of California, Santa Barbara; Sandia National Laboratories and Harvard University were able to fabricate tiny lasers directly on silicon — a huge breakthrough for the semiconductor industry and well beyond.

Not a big fan of laundry day? Well what if you could wash your clothes just by stepping into the sunshine? Thanks to researchers at RMIT University in Melbourne, a self-cleaning textile could make that possible in the very near future. With the help of special nanostructures grown directly into the fabric, these new textiles could degrade organic matter like dirt, dust, and sweat when exposed to a concentrated light source.

To achieve this effect, the nanostructures used by the RMIT University team are made copper and silver. These metals are great at absorbing visible light, and when they’re exposed to light from the sun or even a light bulb, the nanostructures react with increased energy that creates “hot electrons”.

As the computation and communication circuits we build radically miniaturize (i.e. become so low power that 1 picoJoule is sufficient to bang out a bit of information over a wireless transceiver; become so small that 500 square microns of thinned CMOS can hold a reasonable sensor front-end and digital engine), the barrier to introducing these types of interfaces into organisms will get pretty low. Put another way, the rapid pace of computation and communication miniaturization is swiftly blurring the line between the technological base that created us and the technological based we’ve created. Michel Maharbiz, University of California, Berkeley, is giving an overview (june 16, 2016) of recent work in his lab that touches on this concern. Most of the talk will cover their ongoing exploration of the remote control of insects in free flight via implantable radio-equipped miniature neural stimulating systems.; recent results with neural interfaces and extreme miniaturization directions will be discussed. If time permits, he will show recent results building extremely small neural interfaces they call “neural dust,” work done in collaboration with the Carmena, Alon and Rabaey labs.

Radical miniaturization has created the ability to introduce a synthetic neural interface into a complex, multicellular organism, as exemplified by the creation of a “cyborg insect.”

“The rapid pace of computation and communication miniaturization is swiftly blurring the line between technological base we’ve created and the technological base that created us,” explained Dr. Maharbiz. “These combined trends of extreme miniaturization and advanced neural interfaces have enabled us to explore the remote control of insects in free flight via implantable radio-equipped miniature neural stimulating systems.”
