A superabsorbent film promises ecofriendly cooling solutions against heat stress and global warming.

Cool heads clear a pathway for the development of a sustainable cooling technology.

Sabine Hossenfelder report the paper from Prof. Gan's group on her YouTube channel.

Salt-rejecting microchannels help make seawater drinkable using the power of the sun.

The image of an object that is obscured when the light passes through a scattering material can be recovered in real time.

SPIE, the international society for optics and photonics, recently welcomed 83 Members as new Fellows of the Society. Qiaoqiang Gan, KAUST professor of material science engineering, was among the new inductees elected to the Society’s 2023 Fellows Class. The applied physicist joins a notable group of members who have served the optics and photonics community with distinction.

Subwavelength manipulation of light waves with high precision can enable new and exciting applications in spectroscopy, sensing, and medical imaging. Here, we report a unique “rainbow” trapping metasurface for on-chip spectrometers and sensors. Combined with super-resolution image processing, the low-setting 4× optical microscope system resolves a displacement of the resonant position within 35 nm on the plasmonic rainbow trapping metasurface with a tiny area as small as 0.002 mm2.

Imaging through scattering medium is challenging but important for different applications. Here, we report a new strategy to see through random diffusers directly using self-imaging of speckles.

Nanostructured surfaces enable lab-on-a-chip lung cancer diagnosis.
