Introducing Nikola, the emotional android kid

Feb 16, 2022 (Nanowerk News) Researchers from the RIKEN Guardian Robot Project in Japan have made an android child named Nikola that successfully conveys six basic emotions. The new study, published in Frontiers in Psychology ("An Android for Emotional Interaction: Spatiotemporal Validation of Its Facial Expressions"), tested how well people...

Slicing the way to wearable sensor prototypes

Feb 15, 2022 (Nanowerk News) Engineers at UC Berkeley have developed a new technique for making wearable sensors that enables medical researchers to prototype test new designs much faster and at a far lower cost than existing methods. The new technique replaces photolithography — a multistep process used to make...

Researchers ‘tune’ gel-forming protein molecules to boost their versatility for biomedical applications

Feb 15, 2022 (Nanowerk News) Self-assembling protein molecules are versatile materials for medical applications because their ability to form gels can be accelerated or retarded by variations in pH, as well as changes in temperature or ionic strength. These biomaterials, responsive to physiological conditions, can therefore be easily adapted for...

Strong and elastic, yet degradable: protein-based bioplastics

Feb 15, 2022 (Nanowerk News) More than eight million tons of plastic end up in the oceans every year—a serious danger for the environment and health. Biodegradable bioplastics could provide an alternative. In the journal Angewandte Chemie ("Biosynthetic Structural Proteins with Super Plasticity, Extraordinary Mechanical Performance, Biodegradability, Biocompatibility and Information...

Sustainable chemistry based on wood

Feb 15, 2022 (Nanowerk News) Producing materials for solar cells, light-emitting diodes and other organic electronics applications as sustainably as possible: A team from Würzburg's Faculty of Chemistry is working on this. Some hikers carry a small solar power plant with them: a foil is attached to their backpack that...

speed of sound used to measure elasticity of materials

Feb 15, 2022 (Nanowerk News) Researchers at the University of Nottingham have devised a revolutionary new technique for measuring the microscopic elasticity of materials for the first time. Known as SRAS, the technology works by measuring the speed of sound across the material’s surface (Acta Materalia, "Measurement of the single...
