The dark matter particle explorer has measured high-precision cosmic ray helium energy spectrum

Dark Matter Particle Explorer (DAMPE) Collaboration directly observed a spectral softening of helium nuclei at about 34TeV for the first time. This work was based on measurements data of the helium spectrum with kinetic energies from 70 GeV to 80…

A novel nitrogen-doped dual-emission carbon dots as an effective fluorescent probe for ratiometric detection dopamine

How to construct the dual emission nitrogen-doped carbon dots (CDs) by a simple method? Professor Lili Ren with her collaborators proposed a new strategy to prepare such materials which were used to the detection of dopamine. The traditional ratiometric fluorescence…

Nanofibrous filters for PM2.5 filtration

In a paper published in NANO , the author reviewed many kinds of nanofibrous filters including the component, preparation process, and application performances to provide directional guidance for improvement of the air purification field. Poor air quality is worldwide recognized…

Scientists overhear two atoms chatting

How materials behave depends on the interactions between countless atoms. You could see this as a giant group chat in which atoms are continuously exchanging quantum information. Researchers from Delft University of Technology in collaboration with RWTH Aachen University and…

Astonishing quantum experiment in Science raises questions

Quantum systems are considered extremely fragile. Even the smallest interactions with the environment can result in the loss of sensitive quantum effects. In the renowned journal Science , however, researchers from TU Delft, RWTH Aachen University and Forschungszentrum Jülich now…

Report reveals impact of £1.8billion+ on UK science and economy by Diamond Light Source

A recent study by Technopolis and Diamond estimates a cumulative monetised impact of at least £1.8 billion from the UK’s synchrotron, Diamond Light Source, reflecting very favourably with the £1.2 billion investment made in the facility to date. And it…

We know the cost of free choice and locality – in physics and not only

Do we have free choice or are our decisions predetermined? Is physical reality local, or does what we do here and now have an immediate influence on events elsewhere? The answers to these questions are sought by physicists in the…

Nuclear terrorism could be intercepted by neutron-gamma detector that pinpoints source

Scanning technology aimed at detecting small amounts of nuclear materials was unveiled by scientists in Sweden today, with the hope of preventing acts of nuclear terrorism. Bo Cederwall, a professor of physics at KTH Royal Institute of Technology, says the…

Ohio’s Sumit Sharma receives National Science Foundation CAREER award to study metallic nanoparticle

Sumit Sharma, assistant professor of chemical and biomolecular engineering in Ohio University’s Russ College of Engineering and Technology, was recently awarded a National Science Foundation (NSF) Faculty Early Career Development (CAREER) five-year, $511,902 grant to study the adsorption behavior of…

Scientists debut most efficient ‘optical rectennas,’ devices that harvest power from heat

Scientists at the University of Colorado Boulder have tapped into a poltergeist-like property of electrons to design devices that can capture excess heat from their environment–and turn it into usable electricity. The researchers have described their new “optical rectennas” in…

Confirmation of an auroral phenomenon discovered by Finns

A new auroral phenomenon discovered by Finnish researchers a year ago is probably caused by areas of increased oxygen atom density occurring in an atmospheric wave channel. The speculative explanation offered by the researchers gained support from a new study.…

Scientists see chemical short-range order in medium-entropy alloy

Chinese scientists have made direct observations in face-centered cubic VCoNi (medium)-entropy alloys (MEA) and for the first time proposed a convincing identification of subnanoscale chemical short-range order (CSRO). This achievement undisputedly resolves the pressing question of if, what and why…

CCNY team makes single photon switch advance

The ability to turn on and off a physical process with just one photon is a fundamental building block for quantum photonic technologies. Realizing this in a chip-scale architecture is important for scalability, which amplifies a breakthrough by City College…
