Pacemaker capacitor breakthrough promises 300+ years of life-saving power
Apr 25, 2024 (Nanowerk News) Pacemakers are medical devices that make sure that someone's heart beats the way it should. If the heart rhythm is off, the pacemaker delivers a surge of electricity to bring the heart back into rhythm. The pacemaker takes effort into account and delivers faster pulses...
Why can’t robots outrun animals?
Apr 25, 2024 (Nanowerk News) Robotics engineers have worked for decades and invested many millions of research dollars in attempts to create a robot that can walk or run as well as an animal. And yet, it remains the case that many animals are capable of feats that would be...
A novel universal light-based technique to control valley polarization in bulk materials
Apr 24, 2024 (Nanowerk News) An international team of researchers reports in Nature ("Valleytronics in bulk MoS2 with a topologic optical field") a new method that achieves valley polarization in centrosymmetric bulk materials in a non-material-specific way for the first time. This “universal technique” may have major applications linked to...
