Nanoengineers at the University of California, San Diego used an innovative 3D printing technology they developed to manufacture multipurpose fish-shaped microrobots that swim around efficiently in liquids, are chemically powered by hydrogen peroxide, and magnetically controlled.
Compressor disks for aircraft turbines are milled from a single piece of material. During processing, the blades begin to vibrate. Now, a novel clamping system boosts vibration absorption for the blades by more than 400 times, and cuts manufacturing costs. The new clamping system lets manufacturers roughly mill the blades first, and then perform the precise finishing work because the blades no longer vibrate.
New research findings contradict a fundamental assumption about the functioning of "organic" solar cells made of low-cost plastics, suggesting a new strategy for creating inexpensive solar technology. Because organic solar cells are flexible, they could find new applications that are unsuitable for rigid silicon cells such as photovoltaics integrated into buildings, and they have the potential to be lower-cost and less energy-intensive to manufacture than silicon devices.
This Webinar will cover metrological traceability in relation to force measurement. The Webinar will show the attendee common force measurement errors and the importance of calibrating the instrument in the manner it is being used. By the end of the Webinar the attendee should be able to understand metrological traceability hierarchy and identify potential force measurement errors.
Nitinol, a nickel-titanium alloy exhibits two unique properties: superelasticity and shape memory.
Shape memory Nitinol wire can be used to develop implants that may be delivered into the body in a compact shape and activated into their functional form once they have been deployed. Superelasticity occurs at temperatures just above the transformation temperature and allows the material to recover up to 8% strain with a permanent set of 0.5% or less.

Internal-combustion engine designers are continually under pressure to reduce fuel consumption and improve efficiency. ANSYS Forte makes use of the industry’s most accurate fuel chemistry and spray models in simulations to predict the impact of multiple engine design attributes on performance, fuel economy, and emissions.
In collaboration with the State University of New York and the Naval Research Laboratory, NASA Marshall Space Flight Center is developing a hyperspectral estimator to detect trichloroethylene (TCE) in plants. TCE has been a widely used industrial solvent known to be toxic to humans and animals. Although its use and disposal have become more restricted in recent years, TCE is one of the more prevalent groundwater contaminants in the United States.
Initial discoveries/work in the field of hyperpolarization had been instrumental in the field, but without commercialization efforts, there had been little progress in the technology or in-market use.
The imaging process is often affected by the field of view, wavefront aberration, ambient light, as well as the resolution of optical imaging system and detector. As a result, the image information of the object cannot be accurately transferred to the image plane, resulting in distortion, deviation, and noise convolution that affect the ultimate image quality.
Using physical chemistry methods to look at biology at the nanoscale, a Lawrence Berkeley National Laboratory researcher invented a new technology to image single molecules with unprecedented spectral and spatial resolution, thus leading to the first “true-color” super-resolution microscope. The innovation is called SR-STORM, or spectrally resolved stochastic optical reconstruction microscopy. Read more »
