Researchers Create Superfluorescence Using Nanocrystal Superlattices

Superfluorescence Using Nanocrystal Superlattices

To obtain superfluorescence on-demand, researchers used quantum dots made of lead halide perovskites. They conducted optical experiments at -267°C, which gave the final evidence of superfluorescence. A few materials have a tendency to continuously emit light when they are excited by a laser or any other external source. This mechanism is called fluorescence. However, in many quantum systems, ...

An Innovative Method For Manufacturing Plastic Using Much Less Energy

Innovative Method For Manufacturing Plastic

New metal-organic framework can efficiently separate ethane and ethylene to manufacture plastic (polyethylene).  The process runs at room temperatures and requires much less energy.  Generally, manufacturing plastics requires enormous amounts of energy. The most common form of plastic, polyethylene, is made from ethylene – a hydrocarbon molecule found in crude oil refining. To make the manufacturing ...

New Optogenetic Silencing Tool Can Manipulate Complex Biological Processes

New Optogenetic Silencing Tool

New optogenetic tool uses laser to ‘switch off’ the electrically excitable cells.  It reduces harmful side effects through artificial ion fluxes that were inevitable with the existing optogenetic inhibitory tools. Optogenetics is a technique that uses light to alter the molecular event in a particular manner in living tissues, mostly neurons that have been genetically modulated to ...

New Ghost Imaging Technique Enhances Measurements of Gas Molecules

Ghost Imaging Technique

New ghost imaging method measures which gas is present in the atmosphere and at what quantity, with far better accuracy.  It doesn’t require extremely sensitive detectors and powerful light sources to work.  Measuring greenhouse gases in the atmosphere like carbon dioxide, methane, ozone and nitrous oxide is crucial for studying how altering amounts of these gases ...

Galaxy Collisions Fuel The Growth Of Supermassive Black Holes

Supermassive Black Holes grow in Galaxy Collisions

In the largest survey of nearby galaxies, researchers observed hundreds of pairs of colliding galaxy nuclei associated with supermassive black holes. They found that black holes expand rapidly during the last stages of galaxy mergers.  The force of gravity draws two galaxies together: light-year by light-year, inch by inch, the galaxies comes closer as the cosmic ...

The New Fastest Optical Fiber Transmits 1 Petabit/Second

optical fiber

Researchers develop a new optical cable that can transmit data at the rate of one petabit (1000 terabits) per second.  The fiber is as fine as a human hair and less prone to damage.  Fiber optic cables have revolutionized the network communication ever since their inception about 4 decades ago. These cables use thin strands ...

15 Intriguing Facts About Uranium | A Weak Radioactive Metal

Facts About Uranium

Uranium is known to humanity since at least 79 AD when it was used in the ceramic industry (natural oxide form) in several parts of Europe. The chemical element was formally discovered only in 1789, when Martin Heinrich Klaproth, a German chemist stumbled upon a strange, unknown substance (oxide of uranium) during an experiment. Klaproth is ...
