A team of scientists at University of Limerick has discovered that applying pressure to a protein found in egg whites and tears can generate electricity. The researchers from the Bernal Institute observed that crystals of lysozyme, a model protein that is abundant in egg whites of birds as well as in the tears, saliva and milk of mammals can generate electricity when pressed. Their report was published on October 2 in the journal, Applied Physics Letters.
The ability to generate electricity by applying pressure, known as direct piezoelectricity, is a property of materials such as quartz that can convert mechanical energy into electrical energy and vice versa. Such materials are used in a variety of applications ranging from resonators and vibrators in mobile phones to deep ocean sonars and ultrasound imaging. Bone, tendon and wood are long known to possess piezoelectricity.
While piezoelectricity is used all around us, the capacity to generate electricity from this particular protein had not been explored. The extent of the piezoelectricity in lysozyme crystals is significant. It is of the same order of magnitude found in quartz. However, because it is a biological material, it is non toxic so it could have many innovative applications such as electroactive anti-microbial coatings for medical implants, explained Aimee Stapleton, the lead author and an Irish Research Council EMBARK Postgraduate Fellow in the Department of Physics and Bernal Institute of UL.
Crystals of lysozyme are easy to make from natural sources. The high precision structure of lysozyme crystals has been known since 1965, said structural biologist at UL and co-author Professor Tewfik Soulimane. In fact, it is the second protein structure and the first enzyme structure that was ever solved, he added, but we are the first to use these crystals to show the evidence of piezoelectricity.
According to team leader Professor Tofail Syed of ULs Department of Physics, Crystals are the gold-standard for measuring piezoelectricity in non-biological materials. Our team has shown that the same approach can be taken in understanding this effect in biology. This is a new approach as scientists so far have tried to understand piezoelectricity in biology using complex hierarchical structures such as tissues, cells or polypeptides rather than investigating simpler fundamental building blocks.
The discovery may have wide reaching applications and could lead to further research in the area of energy harvesting and flexible electronics for biomedical devices. Future applications of the discovery may include controlling the release of drugs in the body by using lysozyme as a physiologically mediated pump that scavenges energy from its surroundings. Being naturally biocompatible and piezoelectric, lysozyme may present an alternative to conventional piezoelectric energy harvesters, many of which contain toxic elements such as lead.
Professor Luuk van der Wielen, Director of Bernal Institute and Bernal Professor of Biosystems Engineering and Design expressed his delight at this breakthrough by UL scientists. The 109-million Bernal Institute has the ambition to impact the world on the basis of top science in an increasingly international context. The impact of this discovery in the field of biological piezoelectricity will be huge and Bernal scientists are leading from the front the progress in this field, he said.
The full paper, The Direct Piezoelectric Effect in the Globular Protein Lysozyme, by Aimee Stapleton, Mohamed R Noor, John Sweeney, Vincent Casey, Andrei Kholkin, Christophe Silien, Abbasi A. Gandhi, Tewfik Soulimane and Syed A M Tofail, is published in Applied Physics Letters.
Maybe there’s a producive use for libs, after all.
Paging Hillary Clinton’s election-night pillow!!
After what I have lived through, I could probably light up Fenway Park!
No wonder those people starved.
They make pizzaelectricity?
Wait.
Is beer a good conductor?
Damn. Too bad this wasn’t available the night of the last Presidential Election. We could’ve harnessed enough electricity to last many years...
University of Limerick .... really?
Hickory dickory dock...
I’ll bet anchovies produce the most pizzaelectricity.
University of Limerick?
the end of our long blackout fears
is now found in a barrel of tears
just add an egg white
to turn on this light
the better to pour four more beers
"......OH!"
Brilliant
I always keep a couple of pepperoni pizzas in the freezer in case the power goes out.
Pizzaelectricity - Power For The Future!
If the power goes out, how would you cook them?

Donald Trump Proposes Harnessing Liberal Tears To Provide Clean Energy

Donald Trump is proposing a plan to provide the nation with clean energy throughout all fifty states.
The plan reportedly includes as a key component the harnessing of the nations abundant supply of liberal tears, the flow of which would be utilized to power massive hydroelectric generators installed throughout the nation.
Trump and his advisers reportedly got the idea while watching the nations widespread protests against his upcoming presidency, and noticed an abundant flow of salty tears, the energy-giving potential of which was being completely squandered as the teardrops ran off into gutters or evaporated into thin air.
People say Im no good on energy. Wrong. Im great on energy, the best, Trump said in a press conference to announce his new energy plan.
Lets put these tears to work, and lets make Americas energy great again.
Now Chuck Schumer can help solve our energy problem.
“And what is your Science Fair project?”
“It’s about Pizzaelectricity.”
“I see....How does it work?”
“Well, the theory is that you push on this pizza and it makes the electricity to power this light bulb.”
“Did it work?”
“No, it just shot sauce out all over the floor. The dog thought it was great.”
“I’m glad he did because I’m giving you a D.”
Roseanne Barr naked.... gone!
I don’t know.
Electricity and pizzas are phenomena that are hard to understand.
“It is of the same order of magnitude found in quartz. However, because it is a biological material, it is non toxic “
Is Quartz toxic in the way it’s used?
