The Electrochemical Society’s Shelley Minteer and her team of engineers at The University of Utah have developed the first room-temperature fuel cell that uses enzymes to help jet fuel produce electricity without need to ignite the fuel.

The new fuel cells will be able to be used to power portable electronics, off-grid power, and sensors.

The study was published in the American Chemical Society journal ACS Catalysis with Minteer as the senior author.

“The major advance in this research is the ability to use Jet Propellant-8 directly in a fuel cell without having to remove sulfur impurities or operate at very high temperature,” says Minteer. “This work shows that JP-8 and probably others can be used as fuels for low-temperature fuel cells with the right catalysts.”

The standard technique for converting jet fuel to electricity is both difficult, due to the sulfur content, and inefficient, with only 30 percent of the fuel converted to electricity under the best conditions.

This from The University of Utah:

To overcome these constraints, the Utah researchers used JP-8 in an enzymatic fuel cell, which uses JP-8 for fuel and enzymes as catalysts. Enzymes are proteins that can act as catalysts by speeding up chemical reactions. These fuel cells can operate at room temperature and can tolerate sulfur.

We’ve heard a lot about innovation and improvements in the field of battery recently, but safety seems to have been put on the back-burner in lieu of creating a more powerful battery. This issue has now been addressed through funding from the National Institutes of Health in order to make technological breakthroughs in safety innovations for batteries.

According to the National Capital Poison Center, more than 3,500 people of all ages swallow button batteries every year in the United States. In order to combat the permanent injury that this could cause, researchers from MIT, Brigham and Women’s Hospital, and Massachusetts General Hospital have come together to create a coating that prevents batteries from conducing electricity after being swallowed – thereby causing no damage to the gastrointestinal tract.

Prior to this innovation, once a battery was swallowed, it would start to interact with the saliva and create an electric current. This current produces hydroxide, which causes damages to tissue. If not treated, this can cause serious injury within a few hours.

Electrochemical Synthesis of Inorganic Compounds: A Bibliography

Zoltan Nagy, a visiting scholar with the Department of Chemistry at the University of North Carolina at Chapel Hill, asked me to post this kind offer:

I have written a bibliography book about Electrochemical Preparation of Inorganic Compounds (Plenum Press, 1985) with thousands of references.

I have continued to collect the references till the beginning of this year, many-many more thousands. But I realized that I will not be able to use them for anything worthwhile.

I am ready to donate the material to anybody who could make valuable use of it. I still have some of the manuscript of the book on disks.  The later ones are in a varied formats. Some on 3X5 cards, some pages copied from Chemical Abstracts with the appropriate abstract circled. And references with abstracts on CDs since 2005.

I would be ready to donate and ship to somebody interested.

I will keep them till the end of the year, if there is no interest, I’ll just get rid of them.

You can contact Zoltan at nagyz@email.unc.edu.

Here at the ECS Headquarters, we’re celebrating Halloween with a pumpkin decorating contest! Take a look at some of the staff’s creations while we send some interesting Halloween facts your way.

And don’t forget to take a look at the list we’ve compiled of Halloween-themed scientific experiments that are sure to make your holiday just a little bit more eerie.

Where It All Began
Halloween can be traced back about 2,000 years to a Celtic festival called Samhain. In Gaelic, “Samhain” translates to “summer’s end.” Though the exact nature of this festival is not quite understood, it is thought to have been a time of communing with the dead. Most experts believe that Samhain and All Saints’ Day – due to their close proximity on the calendar – influenced each other and combined into the modern day Halloween.

All Hallows’ Eve. Dia de los Muertos. All Saints’ Eve. Day of the Dead. Halloween.

The name and celebrations may change throughout different parts of the world, but the mystery and thrill remain consistent. Here at ECS, we’re drumming up some ways to apply science to this holiday to make it even more eerie.

For kids or just kids at heart, here are some Halloween-themed experiments that are sure to get you in gear for this chilling time of year.

An engineering team from the University of California, San Diego, has developed a new nanoparticle-based material for concentrating solar power. The new research, which has been funded by the U.S. Department of Energy’s SunShot program and published in the journal Nano Energy, aims to convert 90 percent of captured light into heat and make solar costs more competitive.

The new material will be able to withstand temperatures greater than 700° Celsius and can survive many years outdoors, despite exposure to humidity.

“We wanted to create a material that absorbs sunlight that doesn’t let any of it escape. We want the black hole of sunlight,” said Sungho Jin, a professor in the department of Mechanical and Aerospace Engineering at UC San Diego Jacobs School of Engineering.

This from the University of California, San Diego:

The novel material features a “multiscale” surface created by using particles of many sizes ranging from 10 nanometers to 10 micrometers. The multiscale structures can trap and absorb light which contributes to the material’s high efficiency when operated at higher temperatures.

Thermal management represents about 25-30 percent of total costs in a LED bulb, second only to the LEDs themselves.

LED maker Cree has introduced a new consumer bulb that costs less, lasts longer, and consumes less energy than the traditional bulb.

The company’s new bulb does not use the heats sinks that LED bulbs typically use. An LED bulb’s metal collar or other heat sink serves to draw away heat from the bulb to ensure a long life. Accordingly, this makes the bulb more expensive and give it a bulky look.

By eliminating the heat sink, Cree lowered the bulb cost from $9.97 for a “soft white” 40-watt to $7.97.

This from IEE Spectrum:

In its new design, heat is removed from the LEDs through convection, or a flow of air through the bulb. The LEDs are mounted on circuit boards, rather than the metal tower. As the diodes heat up, they draw air from outside the bulb through small vent-like openings at the base and on the top. Because hot air rises, air flows continually through the bulb to cool the LEDs. The airflow circulates whether the bulb is vertical, horizontal or upside down, Watson says.

The new generation bulb will last 25,000 hours and consume 85 percent less energy than an incandescent bulb.

The Swiss company, Center for Electronics and Microtechnology (CSEM), has announced that they have developed the world’s first white solar modules. According to the company, this will allow for a more visually appealing solar module, which will blend into buildings to become virtually invisible.

The current blue-black solar modules are built to maximize sunlight absorption, whereas a white solar module was previously not a color option due to the fact that the color would generally reflect light, rather than absorbing it.

This from CSEM:

CSEM has developed a new technology to make white solar modules, with no visible cells and connections, a reality. It combines a solar cell technology able to convert infrared solar light into electricity and a selective scattering filter, which scatters the whole visible spectrum while transmitting infrared light. Any solar technology based on crystalline silicon can now be used to manufacture white – and colored – modules.
