Chemical engineers have generated ultra-pure green light for the first time.

The new light-emitting diode paves the way for visibly improved color quality in a new generation of ultra-high definition displays for TVs and smartphones.

Electronic devices must first be able to produce ultra-pure red, blue, and green light in order to enable the next generation of displays to show images that are clearer, sharper, richer in detail, and with a more refined range of colors. For the most part, this is already possible for red and blue light; green light, however, has been at the limits of technology.

This is due mainly to human perception, since the eye is able to distinguish between more intermediary green hues than red or blue ones. “This makes the technical production of ultra-pure green very complex, which creates challenges for us when it comes to developing technology and materials,” says Sudhir Kumar of ETH Zurich, co-lead author of the study.

Ultra-pure green plays a key role in extending the color range, or gamut. Ultimately, new hues arise from the technical mixture of three base colors: red, blue, and green. The purer the base colors, the broader the range of hues a screen can display. The new LED is in line with 97 to 99 percent of the international standard for Ultra HD, Rec.2020. By comparison, the purest color TV displays currently available on the market cover on average only 73.11 to 77.72 percent; none exceeds 80 percent.

Engineers have created a high-frequency electronic chip potentially capable of transmitting tens of gigabits of data per second, much faster than the fastest internet available today.

Omeed Momeni, an assistant professor of electrical and computer engineering at University of California, Davis, and doctoral student Hossein Jalili designed the chip using a phased array antenna system. Phased array systems funnel the energy from multiple sources into a single beam that can be narrowly steered and directed to a specific location.

“Phased arrays are pretty difficult to create, especially at higher frequencies,” Momeni says. “We are the first to achieve this much bandwidth at this frequency.”

The chip prototyped by Momeni and Jalili successfully operates at 370 GHz with 52 GHz of bandwidth. For comparison, FM radio waves broadcast between 87.5 and 108 MHz; 4G and LTE cellular networks generally function between 800 MHz and 2.6 GHz with up to 20 MHz of bandwidth.

Spray Drying-Assisted Synthesis of Li₃VO₄/C/CNTs Composites for High-Performance Lithium Ion Battery Anodes

Published in the “Focus Issue of Selected Papers from IMLB 2016 with Invited Papers Celebrating 25 Years of Lithium Ion Batteries.” Graphite-based materials continue to be the most commonly used anode materials in commercial Li-ion batteries (LIBs). However, the practical application of graphite anodes in largescale LIBs may be hindered by safety issues arising from Li dendrite formation on the surface of the anode when cycling at fast rates.

The Journal of The Electrochemical Society (JES) Focus Issue on Mathematical Modeling of Electrochemical Systems at Multiple Scales in Honor of John Newman is now available online, with 72 open access papers published in the ECS Digital Library.

“This focus issue of the Journal of The Electrochemical Society is devoted to the mathematical modeling of electrochemical systems across multiple scales,” the authors say in the focus issue’s preface. “It is dedicated to the work of Professor John Newman from UC Berkeley, who helped establish the field of modeling of electrochemical systems, and is aligned with a previous focus issue and regular symposium on multiscale modeling for electrochemical systems at ECS biannual meetings.”

Newman is a renowned battery researcher and developer of “The Newman Method” — a sophisticated approach to mathematically analyzing complex electrochemical problems. He clarified the physicochemical laws that govern the behavior of electrochemical systems and demonstrated how to use these laws to correctly formulate and solve problems associated with batteries, fuel cells, electrolyzers, and related technologies. He is the author of the book Electrochemical Systems.

A team of engineers has found a simple, economical way to make a nano-sized device that can lift many times its own weight.

Their creation weighs 1.6 milligrams (about as much as five poppy seeds) and can lift 265 milligrams (the weight of about 825 poppy seeds) hundreds of times in a row.

Its strength comes from a process of inserting and removing ions between very thin sheets of molybdenum disulfide (MoS2), an inorganic crystalline mineral compound. It’s a new type of actuator—devices that work like muscles and convert electrical energy to mechanical energy.

The discovery—an “inverted-series-connected (ISC) biomorph actuation device”—appears in Nature.

“We found that by applying a small amount of voltage, the device can lift something that’s far heavier than itself,” says Manish Chhowalla, professor and associate chair of the materials science and engineering department of in the School of Engineering at Rutgers University.

“This is an important finding in the field of electrochemical actuators. The simple restacking of atomically thin sheets of metallic MoS2 leads to actuators that can withstand stresses and strains comparable to or greater than other actuator materials.”

Q&A series with ECS OpenCon 2017 speakers

Brian Nosek, co-founder of the Center for Open Science

ECS will be hosting its first ever OpenCon event on October 1 in National Harbor, MD. OpenCon will be ECS’s first, large community event aimed at creating a culture of change in how research is designed, shared, discussed, and disseminated, with the ultimate goal of making scientific progress faster.

Brian Nosek, co-founder of the Center for Open Science, will be one of the featured speakers at the upcoming ECS OpenCon.

The following conversation is part of a series with speakers from the upcoming ECS OpenCon. Read the rest of the series.

ECS: What was the “aha moment” when you knew the Center for Open Science (COS) was needed?

Brian Nosek: COS began as two laboratory projects with a minimal budget, and a simple idea of testing the reproducibility of current research and building some tools to improve it. From the start, we wanted to help build a future in which the process, content, and outcomes of research are openly accessible by default. All scholarly content would be preserved and connected and transparency would stand as an aspirational good for scholarly work. All stakeholders would be included and respected in the research lifecycle and share the pursuit of truth as the primary incentive and motivation for scholarship.

For the launch of COS, it was less “aha” and more “whoa, we can do this?” Our lab projects received some media attention. One of the outcomes of that was that a number of funders contacted us with interest in the work. In particular, the Laura and John Arnold Foundation offered to support us and provided a very generous donation to elevate our aspirations from small lab effort to nonprofit organization.
