Kalymnos, Greece
Known for Vanadium redox battery

Maria Skyllas-Kazacos AM FTSE (born 26 October 1951) is an Australian chemical engineer best known for her pioneering work of the vanadium redox battery, which she created at the University of New South Wales in the 1980s. [1] [2] Her design used sulfuric acid electrolytes and was patented by the university. In 1999 she was appointed a Member of the Order of Australia "for service to science and technology, particularly in the development of the vanadium redox battery as an alternative power source". [3]

She is an emeritus professor at the University of New South Wales. [4]

Early life

Skyllas-Kazacos was born as Maria Skyllas in Kalymnos, Greece, in 1951 and emigrated to Australia in 1954. She is the oldest of four siblings. [5] She attended Fort Street Girls High School in Sydney, before beginning a degree in industrial chemistry at the University of New South Wales. She graduated with first class honours and the University Medal in 1974. [6]

She completed her PhD in 1978 at the UNSW School of Chemical Technology on the topic of the electrochemistry of molten salts. [7]

Career

After finishing her PhD, Skyllas received a CSIRO Postdoctoral Fellowship and joined Bell Laboratories in the US for her post-doctoral work. [8] [5]

While completing her postdoctoral fellowship at Bell Labs, Skyllas did research on solar energy and focused on the liquid junction solar cell. She researched ways of depositing thin films. She received a patent for a new method of electrodepositing thin films of cadmium selenide. [9] Since Bell labs had to service Bell Telephone Company, Skyllas also did work on batteries. [5] While assisting on experiments with a problem of lead-acid batteries, she discovered soluble lead(IV) ions in the charging and discharging reactions of the lead-acid batteries. [7] She published a paper on this discovery in the Journal of the Electrochemical Society. After giving a poster presentation in Australia on the same subject, she was awarded the Bloom-Gutmann Prize for the best young author under 30. [5]

After leaving Bell Labs, Skyllas went back to Australia and accepted a position as a Queen Elizabeth II Fellow in the School of Physics at the University of New South Wales. In 1982, aged 31, she became a professor in chemical engineering and industrial chemistry. [5] Skyllas married Michael Kazacos, who is also a scientist, and they have three children. [5] [7]

At the University of New South Wales, Skyllas-Kazacos and her research team began working on vanadium compounds. She discovered that highly concentrated pentavalent solutions can be prepared indirectly from tetravalent ions, which is more soluble, combined with scraping of the carbon electrode that made the vanadium oxidation-reduction reactions reversible. [7] [10] Skyllas with her research team then patented the vanadium redox battery in 1988. [7]

<span class="mw-page-title-main">Vanadium redox battery</span> Type of rechargeable flow battery

The vanadium redox battery (VRB), also known as the vanadium flow battery (VFB) or vanadium redox flow battery (VRFB), is a type of rechargeable flow battery. It employs vanadium ions as charge carriers. The battery uses vanadium's ability to exist in a solution in four different oxidation states to make a battery with a single electroactive element instead of two. For several reasons, including their relative bulkiness, vanadium batteries are typically used for grid energy storage, i.e., attached to power plants/electrical grids.

<span class="mw-page-title-main">Flow battery</span> Type of electrochemical cell

A flow battery, or redox flow battery, is a type of electrochemical cell where chemical energy is provided by two chemical components dissolved in liquids that are pumped through the system on separate sides of a membrane. Ion transfer inside the cell occurs through the membrane while both liquids circulate in their own respective space. Cell voltage is chemically determined by the Nernst equation and ranges, in practical applications, from 1.0 to 2.43 volts. The energy capacity is a function of the electrolyte volume and the power is a function of the surface area of the electrodes.

Gaus used new super-resolution fluorescence microscopes to examine the plasma membrane within intact living cells, and study cell signalling at the level of single molecules to better understand how cells "make decisions". A key discovery of Gaus and her team was how T-cells decide to switch on the body's immune system to attack diseases. Her work is of importance to the development of drugs that can work with T-cells in support of the immune system.
