An optical coating like no other

For more than a century, optical coatings have been used to better reflect certain wavelengths of light from lenses and other devices or, conversely, to better transmit certain wavelengths through them. For example, the coatings ...

Sustainable optical fibers developed from methylcellulose

Researchers from Tampere University and Aalto University have developed optical fibers from methylcellulose, a commonly used cellulose derivative. The finding opens new avenues to short-distance optical fibers using sustainable ...

Atomically precise noble metal nanoclusters

Noble metal nanoparticles, such as gold and silver, are well known in the research field of catalysis and biomedical applications. For example, gold and silver nanoparticles can be good catalysts for various chemical transformations, ...

Protein molecules in cells function as miniature antennas

Researchers led by Josef Lazar of the Institute of Organic Chemistry and Biochemistry of the Czech Academy of Sciences (IOCB Prague) have demonstrated that molecules of fluorescent proteins act as antennas with optical properties ...

Researchers invent broad-band tunable terahertz absorber

Recently, a research team led by Prof. SHENG Zhigao from the High Magnetic Field Laboratory of the Hefei Institutes of Physical Science (HFIPS), along with collaborators in HFIPS and ShanghaiTech University, invented a broad-band ...

Strain engineering of 2-D semiconductor and graphene

Strain engineering usually refers to a kind of material processing technology which aims to regulate the properties of materials or optimize related devices' performance by inherent or external strain. In recent years, with ...
