Mini electricity generator made from quantum dots

Machines and electronic devices often generate waste heat that is difficult to utilize. If electricity could be generated from this waste heat, it would offer a means for a clean and sustainable power production: Such a technology ...

Efforts to cut car, plane and ship emissions get small boost

Several countries and companies announced plans Wednesday to stop selling cars that run on gasoline or diesel over the next two decades, as part of efforts to clamp down on a significant source of planet-warming emissions.

Label-free intraoperative histopathology of surgical specimen

Cancer diagnosis is confirmed through histopathology by removing a part of the tissue in question after conducting imaging tests such as MRI, CT, ultrasound, or endoscopy. Based on this clinical diagnosis, the cancerous tissue ...

Smuggling light through opaque materials

Electrical engineers at Duke University have discovered that changing the physical shape of a class of materials commonly used in electronics and near- and mid-infrared photonics—chalcogenide glasses— can extend their ...

New insights into social norms can drive positive social changes

New Curtin research has shed light on why people adopt social norms or conventions, such as hand shaking versus fist bumping, walking on the left or right side of a footpath, or using metric or imperial measurements, by employing ...

Millimeter-scale chip-based supercontinuum generation

In optics, when a collection of nonlinear processes act together on a pump beam, the resulting spectral broadening of the original pump beam gives rise to a supercontinuum. Supercontinuum sources for optical coherence tomography ...

Electrical engineering

Electrical engineering, sometimes referred to as electrical and electronic engineering, is a field of engineering that deals with the study and application of electricity, electronics and electromagnetism. The field first became an identifiable occupation in the late nineteenth century after commercialization of the electric telegraph and electrical power supply. It now covers a range of subtopics including power, electronics, control systems, signal processing and telecommunications.

Electrical engineering may or may not include electronic engineering. Where a distinction is made, usually outside of the United States, electrical engineering is considered to deal with the problems associated with large-scale electrical systems such as power transmission and motor control, whereas electronic engineering deals with the study of small-scale electronic systems including computers and integrated circuits. Alternatively, electrical engineers are usually concerned with using electricity to transmit energy, while electronic engineers are concerned with using electricity to transmit information.
