Improving image sensors for machine vision

Image sensors measure light intensity, but angle, spectrum, and other aspects of light must also be extracted to significantly advance machine vision.

Physicists find signatures of highly entangled quantum matter

Via large-scale simulations on supercomputers, a research team from the Department of Physics, the University of Hong Kong (HKU), discovered clear evidence to characterize a highly entangled quantum matter phase—the quantum ...

Making an object invisible under fluid flow

The invisibility cloak is an artifact that can make the wearer transparent, rendering it undetectable to observers outside. Perhaps, one of the most well-known examples is the invisibility cloak possessed by Harry Potter ...

Scientists use phononic crystals to make dynamic acoustic tweezers

Acoustic tweezers are a powerful tool for contactless manipulation of particles and cells using acoustic radiation forces (ARF) generated by the transfer of acoustic wave momentum. They play an important role in display technology, ...

New DNA origami motor breaks speed record for nano machines

Through a technique known as DNA origami, scientists have created the fastest, most persistent DNA nano motor yet. Angewandte Chemie published the findings, which provide a blueprint for how to optimize the design of motors ...
