Scientists have turned wood into an electrical conductor by making its surface graphene.

Chemist James Tour of Rice University and his colleagues used a laser to blacken a thin film pattern onto a block of pine. The pattern is laser-induced graphene (LIG), a form of the atom-thin carbon material discovered at Rice in 2014.

“It’s a union of the archaic with the newest nanomaterial into a single composite structure,” Tour says.

Previous iterations of LIG were made by heating the surface of a sheet of polyimide, an inexpensive plastic, with a laser. Rather than a flat sheet of hexagonal carbon atoms, LIG is a foam of graphene sheets with one edge attached to the underlying surface and chemically active edges exposed to the air.

Not just any polyimide would produce LIG, and some woods work better than others, Tour says. The research team tried birch and oak, but found that pine’s cross-linked lignocellulose structure made it better for the production of high-quality graphene than woods with a lower lignin content. Lignin is the complex organic polymer that forms rigid cell walls in wood.

A recently published article in The Scientist tells a growingly familiar tale in scholarly publishing: predatory publishers taking advantage of, and often times profiting from, researchers across the globe.

The term “predatory publishers” was coined by University of Colorado Denver librarian, Jeffrey Beall, nearly a decade ago. These publishers disseminate plagiarized or poorly reviewed content, taking advantage of a pay-to-publish open access system by charging authors high prices to disseminate their content while all but eliminating the peer review process. In the case of the article published in The Scientist, these predatory journals even trick established researchers to agree to have their names listed on editorial boards, falsley presenting themselves as credible start-up journals. While this may bolster a journal’s credibility at first glance, it often doesn’t go beyond a name listed on a website, with little to no communication from the journal to the editors.

And if predatory publishers can’t trick honest researchers, that publisher may just recruit a fake editor. A recent investigation, spearheaded by Nature, found that dozens of academic journals have been recruiting fake editors and offering them a place on their editorial board.

According to reports from the Hanken School of Economics, predatory journals increased their publication volume from 53,000 to 420,000 articles per year between 2010 and 2014. Taking article processing charges into account, the report estimates that all-in-all, the predatory publishing market was worth at $74 million in 2014.

When will cars powered by gas-guzzling internal combustion engines become obsolete? Not as soon as it seems, even with the latest automotive news out of Europe.

First, Volvo announced it would begin to phase out the production of cars that run solely on gasoline or diesel by 2019 by only releasing new models that are electric or plug-in hybrids. Then, France and the U.K. declared they would ban sales of gas and diesel-powered cars by 2040. Underscoring this trend is data from Norway, as electric models amounted to 42 percent of Norwegian new car sales in June.

European demand for oil to propel its passenger vehicles has been falling for years. Many experts expect a sharper decline in the years ahead as the shift toward electric vehicles spreads across the world. And that raises questions about whether surging electric vehicle sales will ultimately cause the global oil market, which has grown on average by 1 to 2 percent a year for decades and now totals 96 million barrels per day, to decline after hitting a ceiling.

Energy experts call this concept “peak oil demand.” We are debating when and if this will occur.

Emergency: You need more disposable diapers, right away. You hop into your car and trust your ride will be a safe one. Thanks to your phone’s GPS and the microchips that run it, you map out how to get to the store fast. Once there, the barcode on the package lets you accurately check out your purchase and run. Each step in this process owes a debt to the universities, researchers, students and the federal funding support that got these products and technologies rolling in the first place.

By some tallies, almost two-thirds of the technologies with the most far-reaching impact over the last 50 years stemmed from federally funded R&D at national laboratories and research universities.

The benefits from this investment have trickled down into countless aspects of our everyday lives. Even the internet that allows you to read this article online has its roots in federal dollars: The U.S. Department of Defense supported installation of the first node of a communications network called ARPANET at UCLA back in 1969.

As Congress debates the upcoming budget, its members might remember the economic impacts and improved quality of life that past congressional support of basic and applied research has created.

Scientists have created a single catalyst that could simplify the process of splitting water into hydrogen and oxygen to produce clean energy.

The electrolytic film is a three-layer structure of nickel, graphene, and a compound of iron, manganese, and phosphorus. The foamy nickel gives the film a large surface, the conductive graphene protects the nickel from degrading and the metal phosphide carries out the reaction.

The team of scientists developed the film to overcome barriers that usually make a catalyst good for producing either oxygen or hydrogen, but not both simultaneously.

“Regular metals sometimes oxidize during catalysis,” says Kenton Whitmire, a professor of chemistry at Rice University. “Normally, a hydrogen evolution reaction is done in acid and an oxygen evolution reaction is done in base. We have one material that is stable whether it’s in an acidic or basic solution.”

The discovery builds upon the researchers’ creation of a simple oxygen-evolution catalyst revealed earlier this year. In that work, the team grew a catalyst directly on a semiconducting nanorod array that turned sunlight into energy for solar water splitting.

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.
