Process Engineering

This special field revolves around processes for modifying material properties (milling, cooling), composition (filtration, distillation) and type (oxidation, hydration).

Valuable information is available on a broad range of technologies including material separation, laser processes, measuring techniques and robot engineering in addition to testing methods and coating and materials analysis processes.

High-quality white light produced by four-color laser source

The human eye is as comfortable with white light generated by diode lasers as with that produced by increasingly popular light-emitting diodes (LEDs),…

Manufacturing technology: The vibration that smoothes

In conventional milling operations, a workpiece on a table is typically fed past a rotating multi-tooth cutter, and the entire surface is processed by making a…

Using lasers to vaporize tissue at multiple points simultaneously

UV lasers are a commonly-used tool for cutting into tissue, but the lasers usually make incisions by vaporizing one point at a time in a series of steps. If…

The tarte tatin throws a new light on photovoltaics

Their specialty: manufacturing solar cells that are one thousand times thinner than conventional cells. In order to boost the output of the cells, they have…

Optical Materials Express focus issue on femtosecond direct laser writing

Current advanced femtosecond laser systems offer myriad possibilities to modify materials, from implementing new optical functionality to improving existing…

New technology expands ability to recycle precious metals

Precious metals like platinum and rhodium are very valuable, and also very rare. That makes it increasingly important to recycle these precious metals from a…
