On July 25, a district judge signed an order instructing Apple to pay $506 million to the University of Wisconsin’s Alumni Research Foundation (WARF) for infringing on the research arm’s U.S. patent.

According to reports, WARF sued Apple in 2014 for infringing on U.S. Patent No. 5,781,752, which the foundation claims Apple’s A7, A8, and A8X chips are based on. The new order signed by U.S. District Judge William Conley reinforces the initial infringement charge Apple faced while awarding WARF $4.35 for every iPad and iPhone produced with the previously mentioned chip, totaling some $506 million.

This from ARS Technica:

Apple has already filed papers to appeal the jury’s verdict. A second WARF lawsuit against Apple, accusing a newer generation of products, is on hold while Apple appeals the first verdict.

WARF was one of the first university institutions to dive heavily into patent litigation. In a stream of lawsuits, WARF has demanded that it be paid royalties on a vast number of semiconductors.

The journal impact factors (JIFs) for 2016 have been released, and ECS is pleased to announce that the JIFs for the Journal of The Electrochemical Society (JES) and the ECS Journal of Solid State Science and Technology (JSS) have both risen by 8%.

The JIFs, published in the Journal of Citation Reports (formerly published by Thomson Reuters, now called Clarivate Analytics), are a long-established metric intended to evaluate the relevancy and importance of journals. A journal’s JIF is equivalent to the average number of times its articles were cited over the course of the prior two years.

From 2015 to 2016, the JIF of JES increased from 3.014 to 3.259, and the JIF of JSS climbed from 1.650 to 1.787. These increases mark a continuing trend of growth for both journals.

Each year, the ECS Corrosion Divisions offers the Morris Cohen Graduate Student Award to recognize academic achievements in corrosion science and/or engineering.

Mohsen Esmaily is currently a postdoctoral research fellow at Chalmers University of Technology’s Department of Chemistry and Chemical Engineering in Sweden. He earned a BS degree in materials science in 2009 and an MS degree in advanced engineering materials from the University of Manchester in 2011. He received his PhD degree in materials science and engineering from Chalmers University of Technology in 2016. Esmaily has been working on the corrosion of light alloys including magnesium, aluminum alloys and some selected composites, with a particular interest in corrosion control of cast magnesium alloys through controlling of the solidification process.

Esmaily’s achievements in the field of atmospheric corrosion have been recognized and rewarded by the Royal Swedish Academy of Engineering Sciences, and the Wallenberg Foundation. In 2017, Mohsen co-authored a comprehensive review that summarized decades of Mg corrosion research. He is an active member of The Electrochemical Society, The Minerals, Metals & Materials Society, and Materials Research Society.

Scientists have found that a common enzyme can speed up—by 500 times—the rate-limiting part of the chemical reaction that helps the Earth lock away, or sequester, carbon dioxide in the ocean.

“While the new paper is about a basic chemical mechanism, the implication is that we might better mimic the natural process that stores carbon dioxide in the ocean,” says lead author Adam Subhas, a California Institute of Technology (Caltech) graduate student.

Simple problem, complex answer

The researchers used isotopic labeling and two methods for measuring isotope ratios in solutions and solids to study calcite—a form of calcium carbonate—dissolving in seawater and measure how fast it occurs at a molecular level.

It all started with a very simple, very basic problem: measuring how long it takes for calcite to dissolve in seawater.

“Although a seemingly straightforward problem, the kinetics of the reaction is poorly understood,” says Berelson, professor of earth sciences at the University of Southern California Dornsife College of Letters, Arts, and Sciences.

Brett Lucht is a professor of chemistry at the University of Rhode Island, where his research focuses on organic materials chemistry. Lucht’s research includes the development of novel electrolytes for lithium-ion batteries and other efforts to improve the performance of electrolytes for electric vehicles. Lucht has recently been named associate editor for the Journal of The Electrochemical Society.

The Electrochemical Society: What do you hope to accomplish in your new role as associate editor?

Brett Lucht: I hope to improve the prestige of the journal. While the Journal of The Electrochemical Society is the oldest journal of electrochemical science, competition from other journals has become fierce.  The Electrochemical Society is the largest scientific organization focused on electrochemistry and ECS meetings are very well attended. Thus publishing electrochemical research in the Journal of The Electrochemical Society should be the most prestigious place to publish.

ECS: Why should authors publish in ECS journals?

BL: The Journal of The Electrochemical Society has been in continuous production since 1902—115 years. While many new journals come and go, they are frequently focused on narrow topics which fluctuate in importance.  Publications in the Journal of The Electrochemical Society will last the test of time.  In my area of research, lithium-ion batteries, many new journals are publishing research in this area. However, many of the fundamental research articles providing the foundation for this field were published in the Journal of The Electrochemical Society.

Scientists have found a way to make carbon both very hard and very stretchy by heating it under high pressure. This “compressed glassy carbon”, developed by researchers in China and the US, is also lightweight and could potentially be made in very large quantities. This means it might be a good fit for several sorts of applications, from bulletproof vests to new kinds of electronic devices.

Carbon is a special element because of the way its atoms can form different types of bonds with each other and so form different structures. For example, carbon atoms joined entirely by “sp³” bonds produce diamond, and those joined entirely by “sp²” bonds produce graphite, which can also be separated into single layers of atoms known as graphene. Another form of carbon, known as glassy carbon, is also made from sp² and has properties of both graphite and ceramics.

But the new compressed glassy carbon has a mix of sp³ and sp² bonds, which is what gives it its unusual properties. To make atomic bonds you need some additional energy. When the researchers squeezed several sheets of graphene together at high temperatures, they found certain carbon atoms were exactly in the right position to form sp³ bonds between the layers.

By studying the new material in detail, they found that just over one in five of all its bonds were sp³. This means that most of the atoms are still arranged in a graphene-like structure, but the new bonds make it look more like a large, interconnected network and give it greater strength. Over the small scale of individual graphene sheets, the atoms are arranged in an orderly, hexagonal pattern. But on a larger scale, the sheets are arranged in a disorderly fashion. This is probably what gives it the combined properties of hardness and flexibility.

The global development of industry, technology, and the transportation sector has resulted in massive consumption of fossil fuels. As these fuels are burned, emissions are released—namely carbon dioxide. According to the U.S. Environmental Protection Agency, combustion of petroleum-based products resulted in 6,587 million metric tons of carbon dioxide released into the environment in 2015. But what if we could capture the greenhouse gas and not only convert it, but potentially make a huge profit?

That’s exactly what ECS member Stuart Licht is looking to do.

In a new study, Licht and his team demonstrate using carbon dioxide and solar thermal energy to produce high yields of millimeter-lengths carbon nanotube (CNT) wool at a cost of $660 per ton. According to marketplace values, these CNTs, which have applications ranging from textiles to cement, could then be sold for up to $400,000 per ton.

“We have introduced a new class of materials called ‘Carbon Nanotube Wool,’ which are the first CNTs that can be directly woven into a cloth, as they are of macroscopic length and are cheap to produce,” Licht, a chemistry professor at George Washington University, tells Phys.org. “The sole reactant to produce the CNT wools is the greenhouse gas carbon dioxide.”

Researchers have created a concentrating photovoltaic (CPV) system with embedded microtracking that is capable of producing 50 percent more energy per day than the standard silicon solar cells.

“Solar cells used to be expensive, but now they’re getting really cheap,” says Chris Giebink, an assistant professor of electrical engineering at Penn State.

“As a result, the solar cell is no longer the dominant cost of the energy it produces. The majority of the cost increasingly lies in everything else—the inverter, installation labor, permitting fees, etc.—all the stuff we used to neglect,” he says.

This changing economic landscape has put a premium on high efficiency. In contrast to silicon solar panels, which currently dominate the market at 15 to 20 percent efficiency, concentrating photovoltaics focus sunlight onto smaller, but much more efficient solar cells like those used on satellites, to enable overall efficiencies of 35 to 40 percent.
