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.

Fabricated microvascular networks could create compact fluidic factories

Using direct-write assembly of organic ink, researchers at the University of Illinois at Urbana-Champaign have developed a technique for fabricating three-dimensional microvascular networks. These tiny networks could function as compact fluidic factories in miniature sensors, chemical reactors, or computers used in applications from biomedicine to information technology.

“The fabrication technique produces a pervasive network of interconnected cylindrical channels, which can range from 10 t

’Green’ car tyre produced from two scarcely mixable materials

Dutch technologists have carried out research into a more environmentally friendly car tyre. The scarcely mixable substances silica and rubber were mixed in a ratio that produced a tyre with a low rolling resistance and therefore a lower fuel use for the vehicle to which it will be fitted.

Louis Reuvekamp from the University of Twente mixed silica and rubber under the influence of organosilane. Tyre manufacturers normally use carbon black instead of silica to strengthen the rubber of car ty

Computer calculates when reinforced concrete will rust

Dutch researchers have developed a computer model that calculates the rate at which salt and moisture penetrate reinforced concrete. The model can be used for both the design of new concrete structures as well as analysing the lifespan of existing ones.

Sander Meijers from Delft University of Technology studied the relationship between moisture transport and salt penetration in concrete. Concrete structures such as bridges and dams are designed with as long a lifespan as possible. If these

Underwater sensor system could protect reservoirs, drinking water

A sensor system that can autonomously, continuously and in real-time monitor streams, lakes, ocean bays and other bodies of liquid may help solve problems for environmentalists, manufacturers and those in charge of homeland security, according to Penn State engineers.

“The importance of developing a network sensor technology for operation in liquid environments has recently been highlighted in reports detailing the chemical slurry of antibiotics, estrogen-type hormones, insecticides, nicotin

Tiny cell-based chemical detectors have homeland security potential

A highly sensitive, inexpensive “lab-on-a-chip” that provides warning within seconds of even trace amounts of toxic chemicals in water was designed and demonstrated recently by National Institute of Standards and Technology (NIST) scientists and collaborators.

The prototype sensor system monitors the natural response of bacterial cells bound within the microscopic channels of a plastic microfluidics device–a miniaturized chemical and biochemical analysis system. In the presence of certain

Scientists Awarded Grant To Create ’Artificial Rat Whisker’

Scientists at the University of the West of England and the University of Sheffield have won funding to create a robotic system based on the whiskers of a rat.
The system would mimic the biological rat whisker and would provide an entirely new and groundbreaking modality for mobile robots working in confined spaces.

Known as ‘Whiskerbot’ the project will bring together experts in robotics from UWE with experts from Sheffield University who specialise in computer modelling of the brains o
