White LEDs’ reign as the top light source may soon come to an end with the advent of a new alternative that offers superior directionality.

A photonic crystal or nanoantenna, a 2D structure with periodic arrangement of nano-sized particles, is being developed as a cutting-edge optical control technology. Upon exposure to light, combining a nanoantenna with a phosphor plate produces a harmonious mix of blue and yellow light.

White LEDs have already been improved upon in the form of white laser diodes, or LDs, which consist of yellow phosphors and blue LDs. While the blue LDs are highly directional, the yellow phosphors radiate in all directions, resulting in an undesired mixing of colors.

Nanoscale defects and mechanical stress cause the failure of solid electrolytes.

A group of researchers has claimed to have found the cause of the recurring short-circuiting issues of lithium metal batteries with solid electrolytes. The team, which consists of members from Stanford University and SLAC National Accelerator Laboratory, aims to further the battery technology, which is lightweight, inflammable, energy-dense, and offers quick-charge capabilities. Such a long-lasting solution can help to overcome the barriers when it comes to the adoption of electric vehicles around the world.

Tenth International Conference on Guided Self-Organization (GSO-2022), 12–13 December 2022, Auckland, New Zealand.

A solar distillation device can purify brine from reverse osmosis plants with over 10 percent salinity, as well as water taken directly from the Red Sea. The technology offers double the freshwater production rate of existing salt-rejection solar stills.

Inspired by the floating solar still in “The Life of Pi” movie, KAUST professor Qiaoqiang Gan has developed several nanomaterials and thermal isolation processes to enhance the evaporation of brackish water into pure steam. In 2016 he launched a startup, Sunny Clean Water, that produces low-cost inflatable stills capable of generating 10–20 liters of fresh water per day.

Scientists how now developed a mini tractor beam that can pull atoms and nanoparticles. Scientists have built a real working tractor beam, albeit at a very small scale. The device, which attracts one object to another from a distance, originates in fiction. The term was coined by E. E. Smith who mentioned the technology in his 1931 novel Spacehounds of IPC, and since the 1990s, researchers have worked to make it a reality.

A neuromorphic camera can localize single fluorescent particles to below 20 nm resolution and evaluate the diffusion trajectory with millisecond temporal precision.

Researchers may have made a massive breakthrough in quantum computing. According to a new study published in Nature Nanotechnology, researchers may have discovered a cheaper way to push large-scale quantum computers.

Quantum computing is an intriguing field that has seen quite a bit of growth over the past several years. However, there’s still a lot holding back the massive computers that researchers are working with – namely, their size and the sheer amount of control required to keep large-scale quantum computers running smoothly.

That’s because the larger you make a quantum computer, the more quantum bits, or qubits, it requires to run. And the entire idea of a quantum computer requires you to control every single one of those qubits to keep things running smoothly and efficiently. So, when you make large-scale quantum computers, you end up with a lot of processing power and a lot more qubits to control.

Nanotechnology is a rapidly evolving field with the potential to revolutionize medicine in the future. One of the most promising applications of nanotechnology is the use of nanobots in medicine. Nanobots are microscopic robots that can be programmed to perform specialized activities such as disease diagnosis and treatment. They can be used to diagnose and treat a wide range of conditions, including mental illnesses such as depression and anxiety, as well as physical injuries and illnesses.

One of the most interesting potential applications of nanobots in medicine is the treatment of mental illnesses. Mental illnesses are among the most common and devastating diseases of our time. They can be programmed to constantly map the brain and correct faults as they develop. Alzheimer’s disease may theoretically be treated if a person was implanted with nanobots at birth.

Researchers report a new, highly unusual, structured-light family of 3D topological solitons, the photonic hopfions, where the topological textures and topological numbers can be freely and independently tuned.

We can frequently find in our daily lives a localized wave structure that maintains its shape upon propagation—picture a smoke ring flying in the air. Similar stable structures have been studied in various research fields and can be found in magnets, nuclear systems, and particle physics. In contrast to a ring of smoke, they can be made resilient to perturbations. This is known in mathematics and physics as topological protection.

A typical example is the nanoscale hurricane-like texture of a magnetic field in magnetic thin films, behaving as particles—that is, not changing their shape—called skyrmions. Similar doughnut-shaped (or toroidal) patterns in 3D space, visualizing complex spatial distributions of various properties of a wave, are called hopfions. Achieving such structures with light waves is very elusive.
