Study suggests as an efficient semiconducting material that the prepared material can be utilized in solar cells, optoelectronic, power, semiconductor devices, catalysis, electronics, photonics, sensing, medicine, lithium-ion batteries, filters, anti-reflective & high reflective coatings, water splitting devices and to solve many serious environmental / pollution challenges. It is widely used as a photo-catalyst due to its relatively cheap cost, non toxicity and high chemical stability. It has more applications in various industries like aerospace, sports, paint (to give high gloss, rich depth of color and to replace metal lead), food (to increase the shelf life of products) and cosmetics (UV protection in sunscreens and many other products).

Butterfly wings can do remarkable things with light, and humans are still trying to learn from them. Physicists have now uncovered how subtle differences in the tiny crystals of butterfly wings create stunningly varied patterns of color even among closely related species. The discovery, reported today in the Optical Society’s (OSA) open-access journal Optical Materials Express, could lead to new coatings for manufactured materials that could change color by design, if researchers can figure out how to replicate the wings’ light-manipulating properties.

Harnessing the unique features of the quantum world promises a dramatic speed-up in information processing as compared to the fastest classical machines. Scientists from the Group of Philip Walther from the Faculty of Physics, University of Vienna succeeded in prototyping a new and highly resource efficient model of a quantum computer – the boson sampling computer. The results will be published in the upcoming issue of the renowned scientific journal "Nature Photonics".

A breakthrough in laser science was achieved in Vienna: In the labs of the Photonics Institute at the Vienna University of Technology, a new method of producing bright laser pulses at x-ray energies was developed. The radiation covers a broad energy spectrum and can therefore be used for a wide range of applications, from materials science to medicine. Up until now, similar kinds of radiation could only be produced in particle accelerators (synchrotrons), but now a laser laboratory can also achieve this.

A team, led by scientists from Princeton University, reported online April 22 in the journal Nature Photonics that the folds resulted in a 47 percent increase in electricity generation. Yueh-Lin (Lynn) Loo, the principal investigator, said the finely calibrated folds on the surface of the panels channel light waves and increase the photovoltaic material's exposure to light.
