Photosynthetic microalgae as biocatalysts

The biocatalytic production of chemicals should become considerably more sustainable

06-Mar-2018

A carpet of blue-green algae can literally ‘cloud’ the summer’s swimming pleasure at the lake. This is caused by a few strains of photosynthetically active microalgae, also known as cyanobacteria. Other harmless strains of cyanobacteria have great potential for biotechnological applications and ...

Combating sulphuric acid corrosion at wastewater plants

Microbial induced concrete corrosion causes massive damage to wastewater plants

26-Feb-2018

Wastewater systems are integral to infrastructure in every community. In an ideal world, they operate smoothly and are long-lasting. But biogenic transformation processes in sewage and water treatment systems are a “natural enemy” of conventional plants, frequently causing damage to concrete and ...

Electrostatic design of materials: A fundamentally new approach

Collective electrostatic effects are used to intentionally manipulate material properties

12-May-2017

Computational materials design is traditionally used to improve and further develop already existing materials. Simulations grant a deep insight into the quantum mechanical effects which determine material properties. Egbert Zojer and his team at the Institute of Solid State Physics of TU Graz go ...

Researchers show that enzyme function inhibits battery ageing

22-Mar-2017

It has been known in biology for a long time that the excited oxygen molecule singlet oxygen is the main cause of ageing in cells. To counter this, nature uses an enzyme called superoxide dismutase to eliminate superoxide as a free radical. Superoxide also occurs in cell respiration for energy ...

Piggyback battery for microchips

TU Graz researchers develop new battery concept

19-Aug-2016

Electrochemists at TU Graz have managed to use monocrystalline semiconductor silicon as an active storage electrode in lithium batteries. This enables an integrated power supply to be made for microchips with a rechargeable battery. Small electrical gadgets, such as mobile phones, tablets or ...

TU Graz develops environmentally friendly eco-concrete

04-Aug-2016

Grey on the outside, green inside: The production of “Öko²-Beton” concrete consumes up to 30 percent less CO2 than the production of standard concrete, and yet the “green” concrete is by no means less stable or less convenient to process. Concrete is the most widely used construction material: No ...

Solar cell + battery: TU Graz researches hybrid systems

01-Apr-2016

In the FFG project SolaBat, TU Graz is entering almost new research territory. Photovoltaic cells are to be combined into one device with electrochemical energy storage systems. Whether fair weather or foul, sustainable energy supply must be independent of natural fluctuations of renewable energy ...

Pouring fire on fuels at the nanoscale

11-Aug-2015

There are no magic bullets for global energy needs. But fuel cells in which electrical energy is harnessed directly from live, self-sustaining chemical reactions promise cheaper alternatives to fossil fuels. To facilitate faster energy conversion in these cells, scientists disperse nanoparticles ...

Sensitive to Oxygen: Phosphorescent iridium(III) porphyrin complexes, new tunable oxygen indicators

08-Mar-2011

Monitoring the amount of oxygen in living tissues accurately is a valuable tool in biomedical science, because it enables the elucidation of the course of metabolic processes or the detection of diseases or anomalies. Metal complexes that absorb and emit light are useful as ...

The Battery of the Future: New storage material improves energy density of lithium-ion battery

30-Oct-2009

High-performance energy storage technologies for the automotive industry or mobile phone batteries and notebooks providing long battery times - these visions of the future are being brought one step nearer to the present by scientists from Graz University of Technology. Researchers at the ...
