Physicists proposed fast method for printing nanolasers from rerovskites

PHYSICS & MATH An international research team has developed a new method of synthesizing miniature light sources. It is based on a special laser which produces millions of nanolasers from a perovskite film in a few minutes. Such lasers look like small disks, work at room temperature and have an tunable emission wavelength from 550 to 800 nm.

Untangling the black hole mess

Physicists discover a method on how to unscramble information embedded in black holes University of Maryland scientists provided information from an experiment about the use of quantum mechanics to obtain data inside a black hole which is contrary to modern physics that states that information will be lost forever after being consumed in a black hole.

Physicists discovers planet-like spinning electrons

Electrons are found to spin like planets Rutgers University-New Brunswick researchers discovered planet-like spinning electrons that could innovate solar cells, electronic displays, lasers, and in lighting.

Famous 'sandpile model' shown to move like a traveling sand dune

Researchers at IST Austria find new property of important physical model; results published in PNAS (Photo : Moritz Lang) The so-called Abelian sandpile model has been studied by scientists for more than 30 years to better understand a physical phenomenon called self-organized criticality, which appears in a plethora of real-life situations such as the coordinated firing of brain cells, the spread of forest fires, the distribution of earth quake magnitudes and even in the coordinated behavior of ant colonies.

Cryo-force spectroscopy reveals the mechanical properties of DNA components

Physicists from the University of Basel have developed a new method to examine the elasticity and binding properties of DNA molecules on a surface at extremely low temperatures. With a combination of cryo-force spectroscopy and computer simulations, they were able to show that DNA molecules behave like a chain of small coil springs. The researchers reported their findings in Nature Communications.

Scientists discover new type of magnet

A team of scientists has discovered the first robust example of a new type of magnet--one that holds promise for enhancing the performance of data storage technologies.

Invisible tags: Physicists at TU Dresden write, read and erase using light

Prof. Reineke and his LEXOS team work with simple plastic foils with a thickness of less than 50 μm, which is thinner than a human hair. In these transparent plastic foils, they introduce organic luminescent molecules. In the beginning, these molecules are in an inactive, dark state. By locally using ultraviolet irradiation, it is possible to turn this dark state into an active, luminescent one.

JILA researchers uncover quantum structure of buckyballs

JILA researchers have measured hundreds of individual quantum energy levels in the buckyball, a spherical cage of 60 carbon atoms. It's the largest molecule that has ever been analyzed at this level of experimental detail in the history of quantum mechanics.

Plasmonic pioneers fire away in fight over light

In a new paper in the American Chemical Society journal Nano Letters, Rice chemist Stephan Link and graduate student Yi-Yu Cai make a case that photoluminescence, rather than Raman scattering, gives gold nanoparticles their remarkable light-emitting properties.

3D human epidermal equivalent created using math

Scientists have successfully constructed a three-dimensional human epidermis based on predictions made by their mathematical model of epidermal homeostasis, providing a new tool for basic research and drug development.
