Engineers at the University of Maryland (UMD) have created a new multi-material 3D nanoprinting technique that was featured on the inside front cover of the July 21 issue of Lab on a Chip.

The team’s new technique—capable of printing tiny multi-material structures a fraction of the size of a human hair—offers researchers a faster, cheaper, and more accurate means to 3D print these highly complex structures because the process uses a very simple molding process that is widely used in most microfluidics labs.

To demonstrate their new approach, the researchers 3D nanoprinted a variety of mu...

University of Illinois electrical engineers have cleared another hurdle in high-power semiconductor fabrication by adding the field’s hottest material – beta-gallium oxide – to their arsenal. Beta-gallium oxide is readily available and promises to convert power faster and more efficiently than today’s leading semiconductor materials – gallium nitride and silicon, the researchers said. Their findings are published in the journal ACS Nano.

Flat transistors have become about as small as is physically possible, but researchers addressed this problem by going vertical...

Scientists have developed a wastewater treatment process that uses a common agricultural byproduct to effectively remove pollutants and environmental hormones, which are known to be endocrine disruptors.

The performance of the catalyst that is currently being used to process sewage and wastewater drops significantly with time. Because high efficiency is difficult to achieve given the conditions, the biggest disadvantage of the existing process is the high cost involved...

Physics research groups have generated free electrons from organic semiconductors when combined with a single atomic layer of molybdenum disulfide, a recently discovered 2D semiconductor.

Imagine printing electronic devices using a simple inkjet printer – or even painting a solar panel onto the wall of a building. Such technology would slash the cost of manufacturing electronic devices and enable new ways to integrate them into our everyday lives. Over the last two decades, a type of material called organic semiconductors, made out of molecules or polymers, has been developed for such purposes...
