Wood Biochar Offers Promise of Cheap Supercapacitors

ISTC is investigating wood-biochar’s use as a supercapacitor. The material offers equal power capabilities as activated carbon, but is much less expensive.

 

A team led by Senior Engineer Junhua Jiang published results in the journal Electrocimica Acta, demonstrating the natural microstructures of biochars can be provide effective surface area for electrodes. Currently supercapactitors are often manufactured with corrosive chemicals that create elaborate structures of out of activated carbon.

 

Such procedures are far more expensive and can have environmental consequences.
Supercapacitors are super because they have far greater surface area electrodes than regular capacitors, allowing the rapid collection and release of ions. Cousins of electrochemical batteries, supercapacitors do not yet store as much energy, but they can release energy very quickly, recharge quickly and have high cycling stability. In other words, supercapacitors permit much faster discharge and recharge cycles than a battery is capable of, as well as tolerance of a larger number of discharge/charge cycles.

 

The Illinois Hazardous Waste Research Fund and the HeteroFoaM Center (an Energy Frontier Research Center funded by the U.S. Department of Energy’s Office of Basic Research) supported this study.

Triclosan Shown to Trigger Resistance in Aquatic Ecosystems

A widely used compound to prevent bacterial contamination is persisting in the environment and creating antibacterial resistant strains of bacteria.

 

That is the conclusion of a study by researchers at the Illinois Sustainable Technology Center (ISTC) in Champaign, IL, Loyola University Chicago, and the Cary institute of Ecosystem Studies in Millbrook, NY. The study was published in Environmental Science and Technology a journal of the American Chemical Society.

 

Triclosan is a broad-spectrum anti-microbial compound used in a large variety of consumer products from soap to cosmetics to clothing. The Food and Drug Administration approved the substance and after reports of possible side effects, recently reviewed their own findings, announcing that there is not enough evidence to determine the substance is hazardous.
Meanwhile Proctor and Gamble announced recently they are phasing out the use of Triclosan in its products.

 

John Scott, ISTC’s senior chemist, was co-Principal Investigator with Loyola Biology Professor John J. Kelly in the research which confirmed the presence of Triclosan in stream sediment in the Chicago metropolitan region. Sources for Triclosan contamination includes domestic wastewater, traced to broken sewer pipes and releases of untreated wastewater during high rainfall events.

 

First they conducted field surveys which indicated Triclosan concentrations increased in more highly urbanized areas. They found a significant correlation between the concentration of Triclosan on the stream bottom and Triclosan-resistant bacteria present. Controlled experiments in an artificial stream confirmed the compound triggers resistance and shifts the diversity and composition of bacterial communities. The consequences of altered bacterial communities have not been determined.

 

 

Sphingobacteria
Sphingobacteria is one type most impacted for community composition by Triclosan.

Paper Work Aimed At Preserving Forests, Climate

Craft beers are all the rage. Craft papers not so much. Fresh Press, an agri-fiber laboratory on the University of Illinois campus is pointing the way to turn agricultural waste, not into fuel, but into paper. Their formulations sound like up-scale beer brands: Northwinds Switchgrass Blonde, Double Cooked Soy Brown, Unleashed Mutt.

 

This clever fun has a serious message. We have an abundance of wild grasses, corn stover and other agricultural by-products, some of which end up in landfills. Paper from trees reduces an environmental resource.

 

At noon, Thursday, Oct. 3, Eric Benson, Associate Professor and Chair of Graphic Design at the U of I will discuss how Fresh Press brings together farmers, artists, designers, and academics to demonstrate a more sustainable paper industry. He will present “Fields of Gold, Deckles, and Moulds: Fresh Press and Agri-Fiber Papers” at Room 218 Mechanical Engineering Building.

 

The presentation will also be viewable as a webinar by registering at https://www4.gotomeeting.com/register/440998327. Benson’s appearance is part of the fall sustainability seminar series of the Illinois Sustainable Technology Center.

Congrats to Technology Assistance Program at U of I

The Technology Assistance Program which helps local governments and companies prevent pollution and conserve resources received a national MVP2 Award in Washington DC earlier this month. The ICORE program received its Most Valuable Pollution Prevention Award for saving Illinois more than $6 million over the past four years.

The National Pollution Prevention Roundtable (NPPR) award went to ICORE’s PI, Debra Jacobson and to ISTC environmental engineers Dan Marsch, Mike Springman. The Illinois Conservation of Resources and Energy (ICORE) project is part of the Illinois Sustainable Technology Center (ISTC) and focuses its efforts on populations in small, rural communities in parts of the state which have had little access to conservation or pollution prevention programs. More about the program and the award is available at: http://www.istc.illinois.edu/news/news1.cfm

Engineer Introduces Thermally-Reversible Polymer to Desalination

According to water.org, 780 million people lack access to clean water. The need to provide access to clean water is one of the National Academy of Engineering’s Grand Challenges for Engineering.

 

At noon this Thursday, Sept 12, Dr. Xinying Wang will present “Polymer Assisted Forward Osmosis for Desalination and Water Reuse,” at U of I’s Mechanical Engineering Building, Rm. 218 (1206 W Green St. in Urbana, IL).

 

This webinar, as part of the ISTC’s Sustainable Technology Seminar Series “Sustainability in Action,” will be broadcast live and also archived on our website www.istc.illinois.edu for later viewing. If you cannot attend the event at Rm. 218 MEB, you may view the webinar live by registering at: https://www4.gotomeeting.com/register/864226367. It will also be viewable live at the ISTC Conference Room at 1 Hazelwood Dr., Champaign, IL.

 

Dr. Wang is a Chemical Engineer at the Illinois Sustainable Technology Center, Prairie Research Institute. The following is his abstract for the seminar:

 

“Forward osmosis (FO) for dewatering/desalination applications has received increasing interest due to its potential use of low grade thermal energy, ability to operate at low pressure, and  reduced tendency to foul. Developments in FO are primarily focused on two areas: (a) expanding the availability of draw solutions that generate high osmotic pressure; are easily separated from water using physical and/or chemical means; are non-corrosive, nontoxic, and chemically stable; exhibit near neutral pH; and are inexpensive and (b) developing membranes that exhibit high flux and suitable salt rejection under FO conditions. In this presentation we focus on the challenges of draw solution utilization and regeneration.

 

In this presentation, we will talk about a forward osmosis desalination process that employs a temperature-reversible polymer to recycle the draw solute. In our work, a high concentration MgSO4 solution is used as draw solution. After forward osmosis, the diluted draw solution is mixed with a thermally-reversible polymer, poly (propyleneoxide) –co-poly (ethyleneoxide). This polymer extracts water from the diluted draw solution and the whole solution forms two phases, a polymer-water phase and a concentrated MgSO4 solution phase (bottom). The bottom MgSO4 solution phase is recycled back to the forward osmosis module, while the polymer-water phase is heated above the polymer’s cloudy point (60⁰C) to recycle the polymer and to produce clean water.  Experimental details on the process will be presented.”
