Buckyballs on gold are less exotic than graphene
Graphene consists of carbon atoms that crosslink in a plane to form a flat honeycomb structure. In addition to surprisingly high mechanical stability, the material has exciting electronic properties. The electrons behave like massless particles, whic.....»»
South Africa: Gold mine pollution is poisoning Soweto"s water and soil—study finds food gardens are at risk
For 140 years, gold mines in Johannesburg, South Africa have been leaking wastewater contaminated with heavy metals. The acid mine drainage from Johannesburg's estimated 278 abandoned mines and 200 mine dumps includes uranium (a radioactive metal), t.....»»
International planet hunters unveil massive catalog of strange worlds
While thousands of planets have been discovered around other stars, relatively little is known about them. A NASA catalog featuring 126 exotic, newly discovered worlds includes detailed measurements that allow for comparisons with our own solar syste.....»»
New method may facilitate the use of graphene nanoribbons in nanoelectronics
An international collaborative study that features researchers from Tel Aviv University (TAU), presented a new method for growing ultra-long and ultra-narrow strips of graphene (a derivative of graphite), which exhibit semiconducting properties that.....»»
Study investigates enhancing superconductivity of graphene-calcium superconductors
Superconductors are materials that can conduct electricity with zero resistance when they are cooled below a certain critical temperature. They have applications in several fields, including magnetic resonance imaging, particle accelerators, electric.....»»

Spiny legged 308-million-year-old arachnid discovered in the Mazon Creek locality
More than 300 million years ago, all sorts of arachnids crawled around the Carboniferous coal forests of North America and Europe. These included familiar ones we'd recognize, such as spiders, harvestmen and scorpions—as well as exotic animals that.....»»
A devastating fire 2,200 years ago preserved a moment of life and war in Iron Age Spain, down to a single gold earring
A ruined building in the middle of the Pyrenees records a tragedy for the people who lived there—a devastating fire that burned a settlement to the ground, destroying almost everything except a hidden gold earring. Now archaeologists' excavation of.....»»
LG updates its Tone Free earbuds with ‘pure graphene’ drivers
LG's latest wireless earbuds are claimed to offer better sound quality thanks to the use of pure graphene drivers......»»
Ultrasensitive gas detection empowered by synergy of graphene and sub-comb dynamics
Since the inception of microcomb, whose generation relies on Kerr nonlinearity in microresonator, the coherent soliton state has attracted intense research. Although the operation of sub-comb outputs is straightforward, as a noncoherent comb state,.....»»
Researchers develop increasingly sustainable methods for dissolving gold, silver and copper from recycled materials
Waste from computers and cell phones, solar panels and other discarded electronics are becoming an important source of noble metals alongside mining. Researchers at the University of Helsinki have developed sustainable dissolution methods for noble m.....»»
Thirsty in paradise: Water crises are a growing problem across the Caribbean islands
In the popular imagination, the Caribbean is paradise, an exotic place to escape to. But behind the images of balmy beaches and lush hotel grounds lies a crisis, the likes of which its residents have never experienced......»»
How a GRC consultant passed the CISSP exam in six weeks
Ask any IT security professional which certification they would consider to be the “gold standard” in terms of prestige, credibility, or difficulty, and almost invariably they will answer: the CISSP. If an organization is seeking some peace regar.....»»
Retro gold rush: which emulators are on the App Store, and what"s coming
Apple is allowing emulators on App Store. Here's what's arrived, and what's on the way to play your favorite retro games on your iPhone, updated on May 13.Emulators can bring retro gaming to the iPhoneThe early April changes to the App Store Review G.....»»
Anticipating future discoveries: Scientists explore nontrivial cosmic topology
In a new Physical Review Letters (PRL) study, scientists explore the possibility of nontrivial or exotic topologies in the universe for explaining some of the anomalies seen in Cosmic Microwave Background (CMB)......»»
Electron vortices in graphene detected for the first time
When an ordinary electrical conductor—such as a metal wire—is connected to a battery, the electrons in the conductor are accelerated by the electric field created by the battery. While moving, electrons frequently collide with impurity atoms or v.....»»
Visual observation of photonic Floquet–Bloch oscillations
Recently, the exploration of Bloch oscillations (BOs) in periodically driven quantum systems, equivalent to "Floquet systems," has drawn tremendous attention because their exotic characteristics are profoundly distinct from those in static systems. S.....»»
Scientists create black arsenic visible infrared photodetectors
In recent years, the exceptional structure and fascinating electrical and optical properties of two-dimensional (2D) layered crystals have attracted widespread attention. Examples of such crystals include graphene, black phosphorus (BP), and transiti.....»»
Researchers can now accurately measure the emergence and damping of a plasmonic field
An international research team led by Universität Hamburg, DESY, and Stanford University has developed a new approach to characterize the electric field of arbitrary plasmonic samples, like, for example, gold nanoparticles. Plasmonic materials are o.....»»
Physicists arrange atoms in close proximity, paving way for exploring exotic states of matter
Proximity is key for many quantum phenomena, as interactions between atoms are stronger when the particles are close. In many quantum simulators, scientists arrange atoms as close together as possible to explore exotic states of matter and build new.....»»
