Smart membrane absorbing electromagnetic waves based on polyvinyl chloride/graphene composites
Materials Research Express, 2022 The rapid proliferation and intensive use of electronic devices have led to an increase in electronic pollution, such as electronic noise, electromagnetic interference (EMI), and radiofrequency interference (RFI), which cause malfunctions of electronic ...

Ballistic spin resonance [PDF]
Nature, 2009 The phenomenon of spin resonance has had far reaching influence since its discovery nearly 70 years ago. Electron spin resonance (ESR) driven by high frequency magnetic fields has informed our understanding of quantum mechanics, and finds application in fields as diverse as medicine and quantum information.

Ballistic Anisotropic Magnetoresistance [PDF]
Physical Review Letters, 2005 Electronic transport in ferromagnetic ballistic conductors is predicted to exhibit ballistic anisotropic magnetoresistance (BAMR) - a change in the ballistic conductance with the direction of magnetization. This phenomenon originates from the effect of the spin-orbit interaction on the electronic band structure which leads to a change in the number of ...

Virtual prototyping of medieval weapons for historical reconstruction of siege scenarios starting from topography and archaeological investigations [PDF]
, 2018 Chronicles of sieges to castles or fortresses, using “machinae”, can often be found in historical sources. Moreover, archaeological excavations of castles or fortresses has brought to light rocks or projectiles whose carving suggests a military usage ...
