Considering this knowledge of the retina, the investigators conducted a study in which the goals were to detect and quantify ...

Innovative graphene-silver metasurface biosensor combines nanotech and AI, providing real-time, label-free COVID-19 detection for future diagnostic applications.

A research team from Peking University Yangtze Delta Institute of Optoelectronics has achieved the device-level ...

Hypergap materials reveal a second transparent region above the bandgap, overturning assumptions about optical limits and ...

Abstract: This paper presents a metamaterial perfect absorber as a biosensor in the near-infrared region for biomedical molecular detection, such as urine concentration, malaria infection, bacillus ...

Microwaving water isn't inherently catastrophic. Many people do it daily without issues. But the risks are real: superheating ...

Abstract: This study presents the development of an on-chip terahertz characterization process for low-volume or thin-film materials. A time-domain method based on the transmission of picosecond ...

Waveguides generate digital images directly in the field of vision and enable smart glasses such as the Meta Ray-Ban. We ...

With the rollout of fifth-generation (5G) telecommunications networks and 6G looming on the horizon, the demand for advanced ...

PMPS scored 2.80 for dielectric constant and an ultra-low 0.00087 dissipation factor at 10GHz – significantly lower than PPO achieves (see diagram). “This improvement arises from the higher ...

Also referred to as "mock sun" or "parhelia," sun dogs always appear about 22 degrees of distance from the sun because of the way light refracts through hexagonal ice crystals in ...

A new study reveals that spontaneous emission, a key phenomenon in the interaction between light and atoms, manifests in a ...
