The electrical resistance of a metal is caused by electrons being scattered from impurities in the material’s atomic lattice or from lattice vibrations called phonons. However, it is not affected by ...
A team of researchers has developed a theory to explain how hydrodynamic electron flow could occur in 3D materials and observed it for the first time using a new imaging technique. Electrons flow ...
Princeton researchers have demonstrated a new way of making controllable "quantum wires" in the presence of a magnetic field, according to a new study published in Nature. The researchers detected ...
WEST LAFAYETTE, Ind. – A delicate balance of electrons flowing through the photosynthetic machinery is essential to a plant’s ability to turn sunlight into energy and its survival. Understanding the ...
Key learning points Electrical charges What are free electrons? Cell polarity Conventional current direction Electrons orbit the nucleus. An atom has a neutral charge, because it contains the same ...
This report both complements and extends Technical Reports Series No. 277/2, Absorbed Dose Determination in Photon and Electron Beams - An International Code of Practice, IAEA Technical Reports Series ...
Researchers at MIT have observed “electron whirlpools” for the first time. The bizarre behavior arises when electricity flows as a fluid, which could make for more efficient electronics. Like water, ...
