Engineers are the first to build a high-performance non-reciprocal device on a compact chip with a performance 25 times better than previous work. The new chip, which can handle several watts of power (enough for cellphone transmitters that put out a watt or so of power), was the leading performer in a DARPA SPAR program to miniaturize these devices and improve performance metrics.

Waves, whether they are light waves, sound waves, or any other kind, travel in the same manner in forward and reverse directions — this is known as the principle of reciprocity...

The twist marks the spot. Observations made with the European Southern Observatory’s Very Large Telescope (ESO’s VLT) have revealed the telltale signs of a star system being born...

Dr. Akhilesh K. Gaharwar, associate professor, has developed a highly printable bioink as a platform to generate anatomical-scale functional tissues. This study was recently published in the American Chemical Society’s Applied Materials and Interfaces.

Bioprinting is an emerging additive manufacturing approach that takes biomaterials such as hydrogels and combines them with cells and growth factors, which are then printed to create tissue-like structures that imitate natural tissues.

One application of this technology could be designing patient-specific bone grafts, an area that is gaining interest from researchers and clinicians. Managing bone defects and injuries through traditional treatments tends to be slow and expensive...

Scientists from Hong Kong Baptist University (HKBU) have developed a novel technique that can produce pure therapeutic drugs without the associated side effects.

The approach, which uses a nanostructure fabrication device, can manipulate the chirality of drug molecules by controlling the direction a substrate is rotated within the device, thus eliminating the possible side effects that can arise when people take drugs containing molecules with the incorrect chirality.

Published in the international scientific journal Nature Chemistry, the research findings pave the way towards the mass production of purer, cheaper and ...
