Researcher's Night 2016

We had the pleasure to interview Dr. Athanasios Dimoulas in the past and it seems that this interview is as interesting as the previous one. Athanasios Dimoulas is the head of Epitaxy and the Surface Science Laboratory at NCSR “Demokritos” and he gives us an update with the latest developments of new novel materials in nanoelectronics. The explosion of big data and IoT has resulted in a great need for energy efficient smart devices. Dr Dimoulas shares some of the problems and insights with their research on these hard to develop materials like graphene, Weyl fermions and others. He then reveals how crystals could simulate a “particle accelerator” and test some of the fundamental principles and assumptions in high energy, elementary particle physics and cosmology. This could result in discovering new interesting properties and being able to integrate them faster in electronic devices, capacitors and transistors, in the hope of impacting emerging Quantum Technologies. Interviewed by Sakis Triantafyllakis for Tech Talks Central.

TTC #279 Nanomaterials Improve Speed, Computing and Storage Capacity in Smart Devices

Evangelia Diapouli, Postdoc Researcher in the institute of Nuclear Technology & Radiation Protection at NCSR "Demokritos", talks about their international environmental project which involves linking research discoveries with decision makers ie. state authorities. Their ‘EU Life Program’ funded project offers quantitative assessment for air pollutants, helping officials make informed decisions when it comes to effectively controlling emissions. The team is now continuing their work by researching how these specific concentrations of air pollutants are affecting our lives outdoors and indoors, every day.

TTC #280 Quantitative Assessment of Pollutants for Emission Control

Sakis Triantafyllakis interviews Dr. Elena Dascalaki, senior researcher at the Institute for Environmental Research and Sustainable Development of the National Observatory of Athens on the energy performance and environmental footprint of buildings. Dr. Dascalaki talks about her work at the Energy Conservation Group of the Institute where they study the behavior and energy performance of buildings, the challenges and the importance not only of developing new zero energy structures but also upgrading existing older buildings to have close to zero energy performance, a feat that is substantial especially considering the large amount of old structures all around Europe. Dr. Dascalaki tells us they were instrumental in helping develop the regulations for energy performance of buildings and says they are working on new strategies to upgrade and refurbish old buildings in Greece and Europe to meet the EU mandate that all residential buildings will have to be built or upgraded to be zero or near zero energy, relying solely on renewable sources by 2020. This project she says will be first implemented for all public buildings which will have to make the switch by 2019. Interviewed by Sakis Triantafyllakis for Tech Talks Central.

TTC #281 Super Performing Buildings Run On Zero Energy

Ioannis Raptis, Senior Researcher at NCSR “Demokritos”, discusses food safety. He starts out by mentioning several dangerous food scandals like the horse meat in over 10M burgers, the 3K patients fallen sick by e-coli in food, and the tainted baby milk in China. He continues by pointing out the disadvantages of the time consuming methodology used now to analyse food in the lab. The Food Sniffer (www.foodsniffer.eu), developed by his team as a prototype, consists of the sensing chip, the analysis reader and a computer which could mean a tablet or mobile. It’s advantages are it’s very small and can run with a single battery making it easy to use for analysis in the field. After producing the prototype they’re now planning to include the detection of more pathogens and even more miniaturization to make it even more portable. Interviewed by Yannis Rizopoulos for Tech Talks Central.

TTC #282 A Food Sniffer That Detects Pathogens In Production

Drakoulis Yannoukakos, Director of Research at NCSR “Demokritos” and Director of the Molecular Diagnostics Laboratory, talks about hereditary ovarian and breast cancer. Their research involves hereditary factors that lead to cancer in very young women, between the ages of 30-35 and even younger. By analysing the family genome they’re trying to discover the molecular mutations that are responsible for the early onset of cancer, which although it could be blamed on environmental issues is not that often a cause in so young ages. Interviewed by Vicki Kolovou for Tech Talks Central.

TTC #283 Researching Ovarian and Breast Cancer in Young Women

Dr Athanassios Ganas is the Research Director for Active Tectonics, GPS, Geological Remote Sensing at the Institute of Geodynamics of the National Observatory of Athens. His research is focused on earthquakes and in understanding patterns and behaviour of earth’s cluster based on recording signals from satellites.They have also developed an open-data web platform called GSAC where someone can access geological data from Greece and other countries in the nearby region. He also shares some surprising outcomes and discoveries of their research not only in Greece (Lefkada) but also from the US (California), Chile and Italy. Based on GNSS technology and real-time data, Dr Ganas and his research team are able to estimate accurately an earthquake’s magnitude (in just 2 minutes) and run predictive models for location and time of tsunami attacks.
