Here, we locally improved the rotational flexibility of the phenylenediamine linkage structure in polyetherimide (PEI) to decouple the conjugation of the organic molecule. p -Phenylenediamine (5 mol % ...

Thanks to atomic clocks (and all the worldly forces that influence them), scientists know that Earth's rotation has begun to ...

A series of recent patent filings from Safran Aircraft Engines could hint at some of the innovations being contemplated for ...

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it encompasses both the intrinsic spin of particles and their orbital motion ...

A five-dimensional intermolecular potential energy surface (PES) was developed for the CH4–N2 complex with methane fixed at its experimental equilibrium geometry. Intermolecular potential energies ...

A nano-power integrated circuit is designed to convert the ac output of an electromagnetic micro generator for wearable kinetic energy harvesting to dc usable power. The converter is designed to ...

This paper presents a rotational energy harvester using a brushless dc (BLdc) generator to harvest ambient energy for quadcopter in order to prolong it flight duration. For a quadcopter, its endurance ...

It's been a busy few days for the Magic after trading for Desmond Bane. Monday, we got another update regarding more roster movement/decisions from Orlando. Michael Scotto of HoopsHype reported ...
