Process Engineering

Researchers of Wageningen University and Research Centre in the Netherlands have developed a new clean, process to isolate valuable or undesired components from solids, such as components for food products. In contrast to other conventional processes, the new invention concerns a continuous process that can be controlled easily and secondly, leads to higher extraction yields.

Many odours and flavours are extracted from plant tissues by dissolving in organic solvents, such as hexane and alc

Current electronic technologies can’t create smaller computers and other devices because they are reaching physical limitations, so University of Arkansas scientists seek to harness an electron’s spin to create tiny machines with large memories. To do this, they have built a microscope that may allow them to be the first researchers to measure the properties of electron spin injection in conducting materials.

What happened in Vegas didn’t stay in Vegas for device’s inventors

Back in 2002, Stanford University engineers Kevin Montgomery, PhD, and Carsten Mundt, PhD, found themselves bored at a conference in Las Vegas. So they did what you’d expect from any researchers stuck in Sin City with frequent thoughts about life in outer space: They headed to a casino, downed a few cocktails and drew up a plan for the ideal physiological monitor for astronauts.

But here’s

USC/UT ’Quantum Dot’ nanodevices promise improved night vision goggles, medical sensors and more

Researchers at the University of Southern California and the University of Texas at Austin have built and tested a device based on nanostructures called quantum dots that can sensitively detect infrared radiation in a crucial wavelength range. Quantum dot IR receptor unit.

The atmosphere is opaque to most infrared, but it is transparent for a narrow “window” between 8 a

Researchers from the U.S. Department of Energy’s Argonne National Laboratory and Northern Illinois University have shown that very thin materials can still retain an electric polarization, opening the potential for a wide range of tiny devices.

The researchers found that the ferroelectric phase – the ability to hold a switchable electric polarization – is stable for thicknesses as small as 1.2 nanometers, one-billionth of a meter, or a size several hundred thousand times smaller than t

Two major British landmarks now count among the world’s smallest objects

Scientists & engineers based at the University of Newcastle upon Tyne specialising in miniaturisation technology have recreated North East England’s Tyne Bridge and Antony Gormley’s Angel of the North sculpture so they are smaller than a pinhead and invisible to the naked eye.

The team used a combination of chemistry, physics and mechanical engineering techniques to create the tiny struct
