NIST's Quantum Breakthrough: Single Photons Produced on a Chip

NIST has developed a chip that reliably emits a single photon on demand. This ability will improve the efficiency of QKD (quantum key distribution) as we prepare for the arrival of quantum computers. Quantum computers will upend current cryptology by using Shor's algorithm to rapidly negate the current public/private key secure encryption methods. This has largely been solved by NIST's post quantum cryptology (PQC) algorithms.

Taara Beam provides 25Gbps connectivity over invisible beams of light

Light-based internet provider Taara, which spun out of Alphabet's "moonshot" incubator last year, just launched Taara Beam to provide 25Gbps connectivity within cities over invisible beams of light - line of sight permitting. Unlike last year's Taara Lightbridge, which connects communities separated by water and mountains at distances up to 20km (over 12 miles), the shoebox-sized Beam can be mounted to street poles and roof tops for city-wide connectivity at distances up to 10km. The 8kg (less than 20 pounds) device typically consumes about 90W.

Limitations of probing field-induced response with STM

We demonstrate how the apparent magnetic field induced lattice and CDW intensity change can be explained as a consequence of two independent experimental artifacts: a reconfiguration of atoms at the STM tip apex that alters the amplitudes of CDW modulations, and piezo creep, hysteresis and thermal drift, which artificially distort STM topographs.

Exciplex-enabled high-efficiency, fully stretchable OLEDs

Here we addressed this challenge by incorporating an intrinsically stretchable exciplex-assisted phosphorescent (ExciPh) layer. The elastomer-tolerant triplet-recycling mechanism mitigates exciton energy transfer limitations arising from the insulating elastomer matrix, yielding a light-emitting layer with more than 200% stretchability and an external quantum efficiency (EQE) of 21.7%. To translate this performance to fully stretchable devices, we integrated MXene-contact stretchable electrodes (MCSEs), which feature high mechanical robustness and tunable work function (W

Maximizing perovskite electroluminescence with ordered 3D/2D heterojunction - Nature

Metal halide perovskites have emerged as a material for LEDs owing to exceptional luminescent properties and cost-effective solution processability4,5,6,7,8,9,10. Quasi-2D PeLEDs have demonstrated superior device performance and reproducibility because of their quantum well structures9,11,12,13,14,15,16. However, quasi-2D perovskites are usually composed of hybrid and random 3D-2D phases and face two critical challenges: (1) abundant surface defects will lead to severe non-radiative recombination7,17,18,19 and (2) notable energy disorder will interrupt charge transport, hence reducing device efficiency20,21.

New battery idea gets lots of power out of unusual sulfur chemistry

When the battery starts discharging, the sulfur at the cathode starts losing electrons and forming sulfur tetrachloride (SCl 4), using chloride it stole from the electrolyte. As the electrons flow into the anode, they combine with the sodium, which plates onto the aluminum, forming a layer of sodium metal. Obviously, this wouldn't work with an aqueous electrolyte, given how powerfully sodium reacts with water.
