Researchers developed a bifocal lens based on two layers of liquid crystal (LC) structures. The intensities for the two focal lengths can be easily adjusted by applying external voltage. WASHINGTON — ...

Researchers improved organic solar cell fabrication by controlling molecular assembly, enhancing efficiency and stability, bringing the technology closer to commercial viability. OSCs are a compelling ...

A team of researchers has developed a novel method for using cholesteric liquid crystals in optical microcavities. The platform created by the researchers enables the formation and dynamic tuning of ...

A hexagonal columnar liquid crystal phase was formed by pairing a porphyrin Au III cation and a pentacyanocyclopentadienide (PCCp⁻) anion in water, stabilized by triethylene glycol (TEG) chains.

Spontaneous parametric down-conversion (SPDC), as a source of entangled photons, is of great interest for quantum physics and quantum technology, but so far it could be only implemented in solids.

A study finds chiral structures, with mirror-image configurations, can emerge from nonchiral systems, suggesting new ways to engineer these materials. Hold your hands out in front of you, and no ...

Your science textbook likely told you that matter exists in four states. You know them as solid, liquid, gas, and plasma. For generations, this understanding formed the foundation of physics. Now, a ...

Superconductors are materials that, below a certain critical temperature, exhibit zero electrical resistance and completely expel magnetic fields, a phenomenon known as the Meissner effect. They can ...

All-optical image processing has been viewed as a promising technique for its high computation speed and low power ...
