When military technologies appeared in pre-industrial societies

Peter Turchin from the Complexity Science Hub Vienna (CSH) and an interdisciplinary team of colleagues set out to test competing theories about what drove the evolution of war machines throughout world history. Their study, published today in the journal PLOS ONE, sees the strongest influence on the evolution of military technology coming from world population size, the Read more about When military technologies appeared in pre-industrial societies[…]

Enabling a new technology for modern glass design

Curved glass façades can be stunningly beautiful, but traditional construction methods are extremely expensive. Panes are usually made with “hot bending”, where glass is heated and formed using a mold or specialized machines, an energy-intensive process that generates excess waste in the form of individual molds. Cold-bent glass is a cheaper alternative in which flat Read more about Enabling a new technology for modern glass design[…]

Electricity for the Internet of Things

Thermoelectric materials can convert heat into electrical energy. This is due to the so-called Seebeck effect: If there is a temperature difference between the two ends of such a material, electrical voltage can be generated and current can start to flow. The amount of electrical energy that can be generated at a given temperature difference Read more about Electricity for the Internet of Things[…]

String art – a complex task that digital fabrication can solve

String art is a technique for the creation of visual artwork where images emerge from a set of strings that are spanned between pins. Now, at TU Wien (Vienna) this work can be delegated to a robot – an example of a complex task that digital fabrication can solve. The basic idea of string art Read more about String art – a complex task that digital fabrication can solve[…]

New sensor for measuring electric field strength

TU Wien has developed a sensor for measuring the strength of electric fields, which is much smaller, simpler and less prone to distortion than comparable devices. Accurately measuring electric fields is important in a variety of applications, such as weather forecasting, process control on industrial machinery, or ensuring the safety of people working on high-voltage Read more about New sensor for measuring electric field strength[…]

Ultra-fast electronics with graphene

New experiments have shown that it is possible for extremely high currents to pass through graphene, a form of carbon. This allows imbalances in electric charge to be rapidly rectified. Once again, graphene has proven itself to be a rather special material: an international research team led by Professor Fritz Aumayr from the Institute of Read more about Ultra-fast electronics with graphene[…]

A laser and detector in one: a microscopic sensor has been developed at TU Wien

A laser and detector in one: a microscopic sensor has been developed at TU Wien, which can be used to identify different gases simultaneously. As humans, we sniff out different scents and aromas using chemical receptors in our noses. In technological gas detection, however, there are a whole host of other methods available. One such Read more about A laser and detector in one: a microscopic sensor has been developed at TU Wien[…]
