Articles about 'laser'

Researchers have developed a new method for 3D printing metal that could help reduce costs and make more efficient use of resources.

Researchers have built a nano-engine that could form the basis for future applications in nano-robotics, including robots small enough to enter living cells.

Aditya Sadhanala wanders over to the wall, turns a pulley, and a wooden box about a metre squared swings up and away. Below it gleams an array of carefully positioned lasers, deflectors and sensors surrounding a piece of glass no bigger than a contact lens. He flips a switch and creates a ‘mirage’.

A new method of observing exactly what happens to drug particles as they travel from an asthma inhaler to the lungs could lead to the development of more efficient asthma treatments.

From the kaleidoscopic swirl of a neural network, to ribbons of crystals unfolding like sheets of wrapping paper, to the relief on the faces of villagers in Malawi after their local well was repaired, the breadth of engineering research at the University of Cambridge is reflected in the images produced by the winners of this year’s Department of Engineering photo competition.

A new technique which uses light like a needle to thread long chains of particles could help bring sci-fi concepts such as cloaking devices one step closer to reality.

The ability to design, control and build new materials at the level of individual atoms could open up a whole new world of electronic devices.

A combination of nanotechnology and a unique twisting property of light could lead to new methods for ensuring the purity and safety of pharmaceuticals.

Latest research finds that the trailblazing ‘perovskite’ material used in solar cells can double up as a laser, strongly suggesting the astonishing efficiency levels already achieved in these cells is only part of the journey.

A process that could revolutionise solar energy harvesting has been efficiently demonstrated in solution for the first time.
