Wearable biosensors may pave the way for personalized health and wellness

Penn State engineers are using computational power and data sciences to work on stretchable, flexible — and wearable — devices that could lead to innovations in the health and wellness fields. Credit: Applied Materials and Interfaces Bulky, buzzing and beeping hospital rooms demonstrate that monitoring a patient's health status is an invasive and uncomfortable process, at best, and a dangerous process, at worst. Penn State researchers want to change that and make biosensors that could make he...

Novel MOF is potential next-gen semiconductor

  Sourav Saha’s metal-organic framework research was featured on the cover of ACS Applied Materials & Interfaces on March 18, 2020. Credit: Courtesy Sourav Saha   Metal-organic frameworks (MOFs) are emerging multi-functional materials that are gradually finding their way out of the research labs and into a myriad of real-world applications. For example, MOFs can store dangerous gasses, catalyze chemical reactions, deliver drugs in controlled fashion, and may even be used...

ESEC3 – 3rd Employment Survey for European Chemists (Survey to be completed until March 31)

  This March, for the third time, the European Chemical Society (EuChemS) is launching an investigation into the employment of European chemists, 3rd Employment Survey for European Chemists (ESEC3). This is intended for all chemists working in Europe, of all statuses, of all ages. It is anonymous and the collection of data is secure. The results will then be published, in free access, in the journal Chemistry - A European Journal. We hope many of you will participate, so that this usef...

Lab collaborates to prepare photovoltaic materials research for exascale

  Photovoltaic solar cells are a promising alternative to fossil fuels, but they need to be a lot more efficient before they can go into widespread use. Scientists have pushed current supercomputing power to the limit looking for that improved efficiency, but the arrival of exascale computing within the next few years will allow them to take this quest to the next level. Toward this end, researchers from Berkeley Lab's Computational Research Division (CRD) and the National Energy Rese...

Scientists develop safer lead-based perovskite solar cell

  Researchers at Northern Illinois University and the U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL) in Golden, Colorado, are reporting on February 19, 2020 in the journal Nature on a potential breakthrough in the development of hybrid perovskite solar cells. Considered rising stars in the field of solar energy, perovskite solar cells convert light into electricity. They're potentially cheaper and simpler to produce than traditional silicon-based solar cells...

How Europe’s Most Innovative University Creates Spin-offs

When it comes to creating spin-offs, one university stands out: KU Leuven, Europe’s most innovative university for four years running. This Belgian powerhouse boasts 135 spin-off companies, including ArtiQ, an artificial intelligence based software company that supports doctors in the diagnosis, treatment, and follow up of respiratory illnesses. ArtiQ was co founded by Wim Janssens, a respiratory physician and Associate Professor at KU Leuven, and Marko Topalovic, Janssens’s former PhD student...

Nobel Prize: 97-year-old chemist John Goodenough becomes oldest-ever winner

The 2019 Nobel Prize in Chemistry has been awarded to John Goodenough, Stanley Whittingham and Akira Yoshino. The trio of scientists won for their work on developing rechargeable lithium-ion batteries, which are used in everything from smartphones to pacemakers. At 97-years-old, Professor Goodenough from the US is the oldest-ever Nobel laureate. The announcement was made at the Royal Swedish Academy of Sciences on Wednesday morning, with the winners awarded a share of the nine milli...
