Potential technical applications of printable functional inks.

The video and information in this post relate to an ECS Journal of Solid State Science and Technology focus issue called: Printable Functional Materials for Electronics and Energy Applications.

(Read/download the focus issue now. It’s entirely free.)

Printing technologies in an atmospheric environment offer the potential for low-cost and materials-efficient alternatives for manufacturing electronics and energy devices such as luminescent displays, thin-film transistors, sensors, thin-film photovoltaics, fuel cells, capacitors, and batteries. Significant progress has been made in the area of printable functional organic and inorganic materials including conductors, semiconductors, and dielectric and luminescent materials.

These new printable functional materials have and will continue to enable exciting advances in printed electronics and energy devices. Some examples are printed amorphous oxide semiconductors, organic conductors and semiconductors, inorganic semiconductor nanomaterials, silicon, chalcogenide semiconductors, ceramics, metals, intercalation compounds, and carbon-based materials.

A special focus issue of the ECS Journal of Solid State Science and Technology was created about the publication of state-of-the-art efforts that address a variety of approaches to printable functional materials and device. This focus issue, consisting of a total of 15 papers, includes both invited and contributed papers reflecting recent achievements in printable functional materials and devices.

The topics of these papers span several key ECS technical areas, including batteries, sensors, fuel cells, carbon nanostructures and devices, electronic and photonic devices, and display materials, devices, and processing. The overall collection of this focus issue covers an impressive scope from fundamental science and engineering of printing process, ink chemistry and ink conversion processes, printed devices, and characterizations to the future outlook for printable functional materials and devices.

The revolutionary system can harvest energy from living plants for use in isolated villages.

A revolutionary system with the potential to affect global energy harvesting has recently been developed by a company called Plant-e. The system generates electricity from water-logged plants such as rice grown in patty fields to collect and distribute energy to all areas, even desolate villages.

“It’s based on the principle that plants produce more energy than they need,” said Marjolein Helder, co-founder of Plant-e. “The advantage of this system over wind or solar is that it also works at night and when there’s no wind.”

The science behind the Plant-e technology was conceptualized at Wageningen University in 2007, with the company’s establishment happening thereafter in 2009.

Simply find a plant growing in water and the Plant-e system can begin to harvest energy—whether that plant be rice growing in paddies or simply something growing in your garden.

“It’s just the beginning and lots of things still need to be greatly improved, but the potential is enormous,” said Jacqueline Cramer, professor of sustainable innovation at Utrecht University and former Dutch environment minister.

This new development will lead to accelerated improvements in the materials’ uniformity, stability, and efficiency.

In light of the growth in solar energy research, scientists have been directing a lot of attention toward perovskites. The materials’ wide range of use and potential to outpace silicon-based semiconductors in the field of solar cells makes perovskites an interesting area of research with great potential.

Researchers from the University of Washington, in conjunction with the University of Oxford, have discovered a new quality to perovskites that could help engineer a better solar cell.

The researchers have shown in their research that, contrast to popular belief, the perovskites are uniform in composition. The materials actually contain flaws that can be engineered to improve solar devices even further.

“In that short amount of time, the ability of these materials to convert sunlight directly into electricity is approaching that of today’s silicon-based solar cells, rivaling technology that took 50 years to develop,” said Dane deQuilettes, a University of Washington doctoral student. “But we also suspect there is room for improvement.”

“You’re not going to solve the energy problem by separating paper and plastic. We need to transition out of our dependency on fossil fuels and into renewables. As a society, it is really up to us to change.”

ECS Fellow Héctor D. Abruña recently spoke on the importance of developing better batteries to change the energy landscape at a Charter Day Weekend lecture at Cornell University.

The energy infrastructure as it exists today cannot maintain in its current form in the years to come. The United Nations expects the world’s population to reach 9.6 billion by 2050. Compare this to the current 7.2 billion population and the current issues with the energy infrastructure and the need for change becomes quite apparent.

Fortunately, Abruña and scientists like him are working to move us toward a more energy efficient and sustainable future through developments in fuel cells and batteries, which will power energy efficient and environmentally safe cars, as well as reshape the energy infrastructure itself.

“If we have any hope of solving the energy problems, we need better energy conversion and storage,” said Abruña.

Registration for the ECS Conference on Electrochemical Energy Conversion & Storage with SOFC-XIV is now open. The conference is set to take place this July in Scotland, a fitting venue when looking at the country’s goal of utilizing 100 percent renewable energy by 2020.

In 2012, Scotland pulled 40 percent of its power from renewable resources—a 24 percent increase over 2010.

Scotland is expected to hit the hallway point on the path of obtaining 100 percent renewable this year, making it the perfect platform for some of the top researchers globally in fuel cells and batteries.

ECS student member Linsen Li, along with former member Song Jin, have recently completed the first part of their study focusing on the powerful potential of iron fluoride in lithium-ion batteries, which can improve energy storage.

“In the past, we weren’t able to truly understand what is happening to iron fluoride during battery reactions because other battery components were getting in the way of getting a precise image,” said Linsen Li, graduate student and research assistant at the University of Wisconsin – Madison.

This development will likely impact energy storage and could, in the future, advance large-scale renewable energy storage technologies if the researchers can maximize the cycling performance and efficiency of the low-cost fluoride lithium-ion battery materials.

What better day than Earth Day to highlight the work of ECS member Luke Haverhals, an assistant professor at Bradley University working in novel types of energy storage and conversion through the utilization of renewable, sustainable substrates such as hemp, wood, and silk.

Haverhals is a former student of current ECS 3rd Vice-President Johna Leddy. Since departing from Leddy and the University of Iowa, Haverhals has worked in an area focused on wielding natural fibers using ionic liquids (i.e. enhanced energy conversion devices).

Ionic liquids have been gaining much notoriety lately, with potential game changing electrolytes for energy conversion devices ranging from batteries to fuel cells.

Make sure to join Haverhals and other scientists pioneering world-changing research by joining ECS today and attending our upcoming scientific meeting!

The modern environmental movement was born 45 years ago today. A small group of twenty-somethings with a passion for the environment rallied together to create a more earth-conscious society, establishing what has become known as Earth Day.

The original Earth Day focused primarily on the pollution issue, but this year’s Earth Day is heavily directed towards climate change and the energy infrastructure.

While there may be a war on science happening with people and politicians alike dismissing climate change as mere myth, scientists conducting research in the field state that evidence for warming of the climate system is unequivocal.

When looking at climate change on a global level, the numbers speak for themselves.

• Carbon dioxide levels are at their highest in 650,000 years
• Nine of the 10 warmest years on record have occurred since 2000
• Land ice is dropping by 258 billion metric tons per year
• Sea levels have risen nearly 7” over the past 100 years
