BlockPGP: A new blockchain-based PGP management framework
Pretty Good Privacy (PGP), one of the most widely used cryptographic standards, enables safe end-to-end encryption for emails, messages and other data sharing between users. Essentially, PGP works...
Enhancing high-nickel layered oxide cathodes for lithium-ion batteries
Lithium-based batteries are used to power most existing electric vehicles, yet the amount of time they can keep a vehicle going before they need to be recharged is still somewhat limited. In the...
Gradient Li-rich oxide cathode particles for batteries with minimum oxygen release
Lithium-rich transition metal oxide (Li1+XM1-XO2) cathodes have potential for use in Li-ion batteries, powering electronic devices and electric vehicles. These cathodes have a high energy density,...
High-precision distributed sensing using an entangled quantum network
Quantum-enhanced metrology has been an active area of research for several years now due to its many possible applications, ranging from atomic clocks to biological imaging. Past physics research...
Inverted perovskite solar cells with a power conversion efficiency of 22.3%
Photovoltaic (PV) cells, which can generate energy from the sun, could be very useful in tackling the current environmental crisis. Perovskite PV cells, cells made of metal halide perovskite...
The first observation of the nuclear Barnett effect
The electronic Barnett effect, first observed by Samuel Barnett in 1915, is the magnetization of an uncharged body as it is spun on its long axis. This is caused by a coupling between the angular...
The optomechanical Kerker effect: Controlling light with vibrating nanoparticles
For the Kerker effect to occur, particles need to have electric and magnetic polarizabilities of the same strength. This, however, is very challenging to achieve, as magnetic optical resonances in...
Theory proposes that LIGO/Virgo black holes originate from a first order phase transition
A few years ago, the LIGO/Virgo collaboration detected gravitational waves arising from a binary black hole merger using the two detectors of the Laser Interferometer Gravitational-Wave Observatory...
Three convolutional neural network models for facial expression recognition in the wild
Two researchers at Shanghai University of Electric Power have recently developed and evaluated new neural network models for facial expression recognition (FER) in the wild. Their study, published...
Training neural belief-propagation decoders for quantum error-correcting codes
Two researchers at Université de Sherbrooke, in Canada, have recently developed and trained neural belief-propagation (BP) decoders for quantum low-density parity-check (LDPC) codes. Their study,...
