source:PhysicsworldYour night-mode photos might get a lot crisper thanks to a new device that exploits quantum mechanics to absorb photons more efficiently. Known as a quantum battery, the device stores the energy of the absorbed photons and can be charged simply by shining light on it — great news not just for low-light iPhone photography, but also for solar panels, which could use similar technology to capture the Sun’s energy a lot faster.In a normal medium for storing energy, like a car battery, the time to charge the battery increases in proportion to the battery’s size. Quantum mechanica...

source:PHYS.ORGIn a laboratory under a mountain, physicists are using crystals far colder than frozen air to study ghostly particles, hoping to learn secrets from the beginning of the universe. Researchers at the Cryogenic Underground Observatory for Rare Events (CUORE) announced this week that they had placed some of the most stringent limits yet on the strange possibility that the neutrino is its own antiparticle. Neutrinos are deeply unusual particles, so ethereal and so ubiquitous that they regularly pass through our bodies without us noticing. CUORE has spent the last three years patientl...

source:OPEN.GOVRare earth elements are the driving force behind electric vehicles, and renewable energy generation and are crucial to the manufacture of many high-tech products. However, while they are highly valued across many sectors, they can be problematic to extract due to mineralogical and chemistry issues in processing, which can pose significant challenges for minimising energy and water consumption.Australia is a leader in modern and sustainable approaches to rare earth production. The new Lynas Rare Earths Processing Facility in Kalgoorlie, Western Australia is a prime example that h...

source:EurasiareviewAccording to an estimate of IBM the current daily production of digital information exceeds 2.5 quintillion bytes (equivalent to about 50 million of dual-layer Blu-ray discs, which stacked on top of each other would be 60 km high) and continues to grow at a staggering rate.The vast majority of this data is stored magnetically, where a binary bit, 0 or 1, corresponds to opposite magnetization directions, and is nowadays typically written or erased by current-driven electromagnets. As this process poses fundamental limitations with regards to speed and energy efficiency, the ...
