Engineers have developed a way to visualize the optical properties of objects that are thousands of times small than a grain of sand.

In order to develop high efficiency solar cells and LEDs, researchers need to see how light interacts with objects on the nanoscale. Unfortunately, light is tricky to visualize in relation to small-scale objects.
Engineers from Stanford University, in collaboration with FOM Institute AMOLF, have developed a next-gen optical method to produce high-resolution, 3D images of nanoscale objects. This allows researchers to visualize the optical properties of objects that are several thousandths the size of a grain of sand.
The teams achieved this by combining two technologies: cathodluminescence and tomography.
People in remote locations can now detect viruses and bacteria without leaving their homes.

A team of researchers has developed a device that aims to provide adequate and efficient health care to those who live in remote regions with limited access to medical professionals.
The device utilizes biosensing to detected such viruses and bacteria as HIV and Staph from remote locations. Patients simply take a small blood or saliva sample and apply it to a film made of cellulose paper—each of which is designed to detect a specific bacteria or virus.
This from Popular Science:
The patient would then use a smartphone app to take a picture of the sample and send it to a doctor for diagnosis. Medical professionals, no matter where they are, would receive the cell-fies and look at the bacterial biomarkers in the sample to diagnose the disease. The film is sensitive, disposable, and much cheaper to produce than similar biosensing films.
The editors of the ECS Journal of Solid State Science and Technology are calling for papers for the upcoming focus issue: Novel Applications of Luminescent Optical Materials.
Submission Deadline: July 15, 2015
The research landscape of luminescent and optical materials is rapidly changing due to a need for such materials outside the lighting and display technologies. Novel materials are needed and are developed with luminescent and optical properties appropriately tuned for applications in solar cells, sensors, bio-imaging, light extraction, and related opto-electronics in addition to solid state lighting and display technologies.
A research team from Standford University has developed a high-performance aluminum battery.

Researchers have been attempting to make a commercially viable aluminum-ion battery for years. Now, a team from Stanford University may have developed just the thing to outpace widely used lithium-ion and alkaline batteries.
The new aluminum-ion battery demonstrates high performance, a fast charging time, long-lasting cycles, and is of low cost to produce.
“We have developed a rechargeable aluminum battery that may replace existing storage devices, such as alkaline batteries, which are bad for the environment, and lithium-ion batteries, which occasionally burst into flames,” said Hongjie Dai, a professor of chemistry at Stanford.
The researchers were able to achieve this novel battery by applying graphite as the cathode material.

Andrea Guenzel, ECS Publications Specialist, recently spotted a CNN article on quantum dots and how they’re poised to change industry.
The technology behind Edison’s incandescent blub may be a thing of the past, but the warm, gentle glow that it produced may be making its way back into your living room.
But we’re not scrapping the advancements in LEDs and regressing to old technology to do this. Instead, we’re turning our attention to quantum dots—the tiny crystal-like particles that are 10,000 times smaller than the width of human hair.
And the dots’ applications do not end simply at bulbs. These tiny bursts of light are expected to impact displays, solar cells, and cancer imaging equipment as well.
The Excrevator will help put an end to emptying pit latrines by hand.

Critical technology gaps in water, sanitation, and hygiene are being faced all over the world. According to UNICEF, 2.5 billion people—36 percent of the world’s population—don’t have access to a toilet. Due to this, many people in the developing world either practice open defecation or utilize pit latrines. In turn, this leads to a high risk of contracting diseases ranging from typhoid to hepatitis.
Tate Rogers, an engineering student from North Carolina State University, decided that something has to be done about this. In 2011, Rogers began developing a device that would help those in the developing world more safely deal with raw sewage.
It’s four years later, and the project is still under way—but it’s beginning to come to fruition.
Hubert Gasteiger of Technische Universität München’s Institute for Technical Electrochemistry will be awarded the 2015 Physical and Analytical Electrochemistry Division David C. Grahame Award for his work focusing on materials, electrodes, and diagnostics development for fuel cells and batteries.
The prestigious award was established in 1981 to encourage excellence in physical electrochemistry research.
Hubert A. Gasteiger has touched many aspects of electrochemical science, from academia to industry. He studied at UC Berkeley before he went on to do a one-year postdoctoral fellowship at the Lawrence Berkeley National Laboratory, followed by academic research with Jürgen Behm at Ulm University—where he established a research group in heterogeneous gas-phase catalysis and electrocatalysis.
The hybrid supercapacitor can store large amounts of energy, recharge quickly, and last for more than 10,000 recharge cycles.

Researchers from UCLA’s California NanoSystems Institute (CNSI) have developed a new generation of supercapacitors that not only emphasizes the best inherent properties of the supercapacitor itself, but also combines it with some of the best qualities of batteries to make a new energy storage medium.
The new supercapacitor is paper-thin and has an extremely fast recharge time. Additionally, it can last more than 10,000 recharge cycles.
Researchers believe this new development will yield real-world potential to address energy issues and improve personal electronics.
“The microsupercapacitor is a new evolving configuration, a very small rechargeable power source with a much higher capacity than previous lithium thin-film microbatteries,” said Maher El-Kady, co-author of the study and postdoctoral scholar.
