The future of technology

The iconic Moore’s law has guided Silicon Valley and the technology industry at large for over 50 years. Moore’s prediction that the number of transistors on a chip would double every two years (which he first articulated at an ECS meeting in 1964) bolstered businesses and the economy, as well as took society away from the giant mainframes of the 1960s to today’s era of portable electronics.

But research has begun to plateau and keeping up with the pace of Moore’s law has proven to be extremely difficult. Now, many tech-based industries find themselves in a vulnerable position, wondering how far we can push technology.

Better materials, better chips

In an effort to continue Moore’s law and produce the next generation of electronic devices, researchers have begun looking to new materials and potentially even new designs to create smaller, cheaper, and faster chips.

“People keep saying of other semiconductors, ‘This will be the material for the next generation of devices,’” says Fan Ren, professor at the University of Florida and technical editor of the ECS Journal of Solid State Science and Technology. “However, it hasn’t really changed. Silicon is still dominating.”

Silicon has facilitated the growth predicted by Moore’s law for the past decades, but it is now becoming much more difficult to continue that path.

Whether you’re a Star Wars superfan or find yourself lost when the conversation turns to discussions of the feasibility of the Death Star, you can probably identify the epic space series’ iconic lightsaber. The lightsaber has become one of the most recognizable images in popular culture, but is it purely fiction or could it be a reality?

According to the Star Wars books, lightsabers are pretty complex devices but essentially boil down to a few key elements: a power source and emitter to create light, a crystal to focus the light into a blade, a blade containment field, and a negatively charged fissure. In the Star Wars galaxy, a lightsaber creates energy, focuses it, and contains it.

But that’s fiction and those ideas are not in line with current science and technology. So how could we build a lightsaber with the tools we have today?

Many people look initially to laser technology when discussing a practical lightsaber. It’s unrealistic to say that light could be the source of the blade seeing as light has no mass (creating a pretty insufficient weapon), but lasers could be an alternative. It may seem contradictory to say that lasers could be the blade in a lightsaber when lasers are essentially light focused to a very fine point, but as Looper puts it, light is to a laser what a tree is to paper.

A giant among giants

Harry Kroto, distinguished chemist and pioneering nanocarbons researcher, passed away on April 30, 2016 at the age of 76. Kroto, a giant among giants, made an immense impact not only on ECS and its scientific discipline – but the world at large.

“Harry Kroto’s passing is a great loss to science and society as a whole,” says Bruce Weisman, professor at Rice University and division chair of the ECS Nanocarbons Division. “He was an exceptional researcher whose 1985 work with Rick Smalley and Bob Curl launched the field of nanocarbons research and nanotechnology.”

Revolutionizing chemistry

That work conducted by Kroto, Smalley, and Curl yielded the discovery of the C60 structure that became known as the buckminsterfullerene (or the “buckyball” for short). Prior to this breakthrough, there were only two known forms of pure carbon: graphite and diamond. The work opened a new branch in chemistry with unbound possibilities, earning the scientists the 1996 Nobel Prize in Chemistry.

The field of nanocarbons and fullerenes, since the discovery by Kroto and company, has evolved into an area with almost limitless potential. The applications for this scientific discipline are wide-ranging – from energy harvesting to sensing and biosensing to biomedical applications and far beyond. Research in this field continues to fill the pages of scholarly journals, making possible innovations that were not even conceived before the seminal 1985 work.

The U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) has recently announced up to $30 million in funding for a new program that focuses on renewable energy to convert air and water into cost-competitive liquid fuels.

The program, titled Renewable Energy to Fuels through Utilization of Energy-dense Liquids (REFUEL), is aimed at developing technologies that use renewable energy to convert air and water into carbon neutral liquid fuels – which can be converted into hydrogen or electricity to provide power for sustainable transportation.

The majority of vehicles in the transportation sector depend on liquid fuels such as gasoline or diesel to operate. While liquid fuels are energy dense and can be stored for a long period of time, liquid fossil fuels emit significant amounts of carbon dioxide into the environment. These emissions account for over 20 percent of the U.S.’s total greenhouse gas emissions and contribute to the overall effects of climate change.

We talk about climate change a lot here at ECS, but the realities of rising sea levels and record-breaking carbon emissions in the atmosphere makes for pretty grim material. In an effort to drum up support for environmental protection, Defend Our Future teamed up with Funny or Die to give the climate change discussion a little comic relief.

Cloris Leachman, Michael Lerner, and a few other funny people discuss how seniors view climate change – or as they describe it, the “after I’m dead problem.”

After all the laughs, Defend our Future has one simple message: old people don’t care about climate change, that’s why you have to.

Building a sustainable future

Over 40 years ago, the modern environmental movement was born. Passion and concern drove a small group of twenty-somethings together in a rallying cry to create a more environment-conscious society, establishing what has become known as Earth Day.

The original Earth Day focused on the issues of pollution, but today’s modern Earth Day focuses the pressing global issue of climate change.

Global challenges

Currently, carbon dioxide levels in the air are at their highest in over 650,000 years, the global temperature has risen 1.4°F since 1880, and the sea level nearly 7” over the past 100 years.

While a few people and politicians may sill dismiss climate change, around 200 worldwide scientific organizations now formally hold the position that climate change has been caused by human action. Additionally, nearly 170 countries are preparing to sign the Paris Climate Agreement today, which will put global plans into motion in an effort to tackle the issue of rising temperatures.

The science of renewable energy

Here at ECS, we believe the path to stopping climate change and tackling these issues that are devastating the environment begins with science.

With population growth and industrialization, global energy needs continue to grow. Economic, political, and environmental issues are largely dictated by energy needs.

In early December of 2015, Sen. Jeff Flake (R-Ariz.) penned what he deemed the “Wastebook” – a report detailing what the senator believes to be wasteful federal spending, specifically targeted at research dollars.

The report took aim at research the fiscal conservative considered a waste of federal cash, including projects he summed up as a “shrimp fight club,” a study of cows in China, an exploration of why obese women can’t get dates, and a look at shrimp on a treadmill.

Earlier this month, those very same scientists that Flake criticized and reduced their research to mere waste took to Pennsylvania Avenue to reinforce the legitimacy of their work.

Researchers respond

“I am rock solid about my research. I know it is very good,” said Sheila Patek, an associate professor of biology at Duke University who led the so-called shrimp fight club study. “But this ‘Wastebook’ targeted a short paper that was the first paper in my young graduate student’s career. He is from a long line of firefighters. His father, his uncle, his grandfather. There aren’t any other scientists in his family. They are very proud of him. He is extremely civic-minded. I don’t think I’ve had anyone in my lab like that. And this has been crushing for him.”
