Water compresses under a high gradient electric field

04-Jul-2018

Modern civilization relies on water's incompressibility--it's something we take for granted. Hydraulic systems harness the virtual non-compressibility of fluids like water or oil to multiply mechanical force. Bulldozers, cranes, and other heavy machinery exploit the physics of hydraulics, as do ...

Rapid spectroscopic process analysis

Empowers development and control of flexible production processes

12-Jun-2018

Global competition in the chemical industry, with increasingly dynamic markets and product cycles, requires shorter process development times and flexible and efficient production processes. By combining micro chemical engineering and spectroscopic process analysis in different spectral ranges, ...

3D X-rays measure particle movement inside lithium ion batteries

23-May-2018

Lithium ion batteries have come a long way since their introduction in the late 1990s. They're used in many everyday devices, such as laptop computers, mobile phones, and medical devices, as well as automotive and aerospace platforms, and others. However, lithium ion battery performance still can ...

Graphene origami as a mechanically tunable plasmonic structure for infrared detection

26-Apr-2018

Soldiers often need to see through smoke, fog, dust or any other airborne obscurant and detect the presence of toxins or other chemicals in the field or on the front lines. To identify those chemicals, they use infrared (IR) sensors and spectroscopy, which allow a specific color of light to shine ...

Turning polymer films into self-sensing high-tech actuators

28-Mar-2018

They might only be made from thin silicon film, but they can squeeze down hard, deliver a powerful thrust, vibrate or hold any required position. And because they can act as sensors, they are becoming important tools in technical applications. Stefan Seelecke and his team at Saarland University ...

Helium ions open whole new world of materials

01-Mar-2018

They have illustrated their findings with the creation of nano 'sieves' that can help separate molecules down to an unprecedented size 10,000 times finer than a human hair. Professor Ostrikov, from QUT's Science and Engineering Faculty and Institute of Health and Biomedical Innovation, said this ...

Combining metalens with an artificial muscle

27-Feb-2018

Inspired by the human eye, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed an adaptive metalens, that is essentially a flat, electronically controlled artificial eye. The adaptive metalens simultaneously controls for three of the major ...

3-D printing breakthrough for lightweight syntactic foams could help submarines dive deeper

09-Feb-2018

A team of materials scientists at NYU Tandon School of Engineering have developed the first process to 3D print components of syntactic foam, extremely strong and lightweight composites used in vehicles, airplanes, and ships. Their breakthrough holds particular promise for submarines because it ...

3-D printing improves cell adhesion and strength of PDMS polymer

25-Jan-2018

Combining two different polymer forms can switch manufacturing of silicone parts from molding, casting and spin coating of simple forms to 3-D printing of complex geometries with better mechanical characteristics and better biological adhesion, according to a team of Penn State researchers. "So ...

Smaller laser - more power

25-Jan-2018

An international team of scientists has produced the first high-powered, randomly polarised laser beam with a "Q switch" laser, which typically emits pulses of light so brief that they're measured in nanoseconds. Lasers are a critical part of modern technology--they're used in everything from our ...
