Over 100 researchers were guided through a brainstorming and working group session with the theme of improving access to clean water and sanitation in developing countries.

ECS is awarding $210,000 of seed funding to four innovative research projects addressing critical technology gaps in water, sanitation, and hygiene challenges being faced around the world.

Winners of the first Science for Solving Society’s Problems Challenge:

Artificial Biofilms for Sanitary/Hygienic Interface Technologies (A-Bio SHIT)
Plamen Atanassov, University of New Mexico, $70,000
Interfaces: Produce bio-catalytic septic cleaning materials that incorporate microorganisms removing organic and inorganic contaminants, while simultaneously creating electricity (or hydrocarbon fuel) for energy generation in support of a sustainable and portable system.

In-situ Electrochemical Generation of the Fenton Reagent for Wastewater Treatment
Luis Godinez, Centro de Investigacion y Desarrollo Tecnologico en Electroquimica SC, Mexico, $50,000
Disinfection: Study the electro-Fenton approach using activated carbon to efficiently oxidize most of the organic and biological materials present in sanitary wastewater so that recycling of the wastewater might be possible.

Neus Sabate, Institut de Microelectrónica de Barcelona (CSIC); Juan Pablo Esquivel, University of Washington; Erik Kjeang, Simon Fraser University, $50,000
Monitoring and Measurement: Develop a non-toxic portable source of power for water measuring and monitoring systems, which will not require recycling facilities. Using inexpensive materials such as paper, nanoporous carbon electrodes and organic redox species, the team will strive to create a biodegradable and even compostable power source.

More than MERe microbes: Microbial Electrochemical Reactors for water reuse in Africa
Gemma Reguera, Michigan State University, $40,000
Chemical Conversion: Develop microbial electrochemical reactors that harvest energy from human waste substrates using bioanodes engineered to process the waste into biofuels while simultaneously cleaning water for reuse. The microbial catalysts will be selected for their efficiency at processing the wastes, but also for their versatility to process other residential and agricultural waste substrates. This will provide an affordable, easy to operate system for the decentralized processing of a wide range of wastes for improved sanitation, water reuse, and energy independence.


2014 ECS/SMEQ Meeting in the Books

Edison Theatre

“Pee to Energy” demo at the Edison Theatre in the exhibit hall in Cancun, Mexico. Rob Gerth, Gerri Botte, and Madhi Muthuvel getting ready to go.

I’m working on an official review of what happened at the meeting. In the meantime, I’ve been looking at some of the photos which got me thinking about the adventure that is an ECS meeting.

A couple of quick hits first:


ECS Connections to 2014 Physics Nobel Prize

The 2014 Nobel Prize in Physics has been awarded to Shuji Nakamura, professor of materials and of electrical and computer engineering at the University of California and 2010 ECS Plenary speaker.

The prize is for the invention of efficient blue light-emitting diodes, which has enabled bright and energy-saving white light sources, and is shared with ECS member Isamu Akasaki of Meijo University and Nagoya University, Japan; and Hiroshi Amano of Nagoya University.

In his plenary talk at the 218th ECS Meeting in Las Vegas, Nevada, Nakamura described the current status of III-nitride based light emitting diodes (LEDs) and laser diodes. Nitride-based white LEDs have been used for many application such as LCD TV backlight, lighting for inside/outside applications and others.

According to the Royal Swedish Academy of Sciences, when Nakamura, Akasaki and Amono “produced bright blue light beams from their semiconductors in the early 1990s, they triggered a fundamental transformation of lighting technology. Red and green diodes had been around for a long time, but without blue light, white lamps could not be created. Despite considerable efforts, both in the scientific community and in industry, the blue LED had remained a challenge for three decades.”

The LED lamp “holds great promise for increasing the quality of life for over 1.5 billion people around the world who lack access to electricity grids,” the academy continued.

Here’s a list of articles in the ECS Digital Library written by the 2014 Physics Nobel Prize Winners. You can look at them for free:

First Graphene-Based Flexible Display Produced

"This is a significant step forward to enable fully wearable and flexible devices ." -Andrea Ferrari, Director of the Cambridge Graphene Centre

“This is a significant step forward to enable fully wearable and flexible devices .”
-Andrea Ferrari, Director of the Cambridge Graphene Centre

There has been quite the buzz around graphene lately. With this material being among the strongest and most lightweight known, it has the potential to revolutionize industries from healthcare to electronics. And revolutionize is exactly what the Cambridge Graphene Centre (CGC) and Plastic Logic have set out to do.

With the CGC’s graphene expertise and Plastic Logic’s already developed technology for flexible electronics, the two came together to demonstrate the first graphene-based flexible display.

This from University of Cambridge:

The new prototype is an active matrix electrophoretic display, similar to the screens used in today’s e-readers, except it is made of flexible plastic instead of glass. In contrast to conventional displays, the pixel electronics, or backplane, of this display includes a solution-processed graphene electrode, which replaces the sputtered metal electrode layer within Plastic Logic’s conventional devices, bringing product and process benefits.

Atomic Layer Etch (ALEt) and Atomic Layer Clean (ALC) are emerging as enabling technologies for sub 10nm technology nodes. At these scales performance will be extremely sensitive to process variation.

Atomic layer processes are the most promising path to deliver the precision needed. However, many areas of ALEt and ALC are in need of improved fundamental understanding and process development. This focus issue will cover state-of-the-art efforts that address a variety of approaches to ALE and ALC.

Topics of interest include but are not limited to:

  • Surface reaction chemistry and its impact on selectivity
  • Plasma ion energy distribution and control methods
  • Novel plasma sources and potential application to ALEt & ALC
  • Innovative approaches to atomic layer material removal
  • Novel device applications of ALEt & ALC
  • Process chamber design considerations
  • Advanced delivery of chemicals to processing chambers
  • Metrology and control of ALEt & ALC
  • Device performance impact
  • Synthesis of new chemistries for ALEt & ALC application
  • Damage free surface defect removal
  • Process and discharge modeling
