A protective layer applied to gold nanoparticles can boost its resilience.

For the first time, researchers including those at the University of Tokyo discovered a way to improve the durability of gold catalysts by creating a protective layer of metal oxide clusters. The enhanced gold catalysts can withstand a greater range of physical environments compared to unprotected equivalent materials.

Apple is reportedly looking to use graphene to reduce thermal issues on the iPhone 16 Pro series.

A research team at the Korea Institute of Science and Technology (KIST) has developed a thermally refractory material that maintains its optical properties even at temperatures of 1,000 degrees Celsius and in strong ultraviolet illumination. The material can be used in various applications ranging from space and aerospace to thermal photovoltaic (TPV) systems.

Thermal radiation is the term used to define the electromagnetic radiation emitted from all matter whose temperature is above absolute zero. The radiation results from the heat generated when charges in the material move and are released in the form of electromagnetic radiation.

Scientists have been working on tapping this radiation as a form of energy source. The heat from facilities such as thermal power generation plants and industrial sites can be repurposed for heating, cooling, and even energy production when suitable thermal refractory materials are available.

Researchers have unveiled a pioneering “bone bandage” that not only regenerates damaged bones in mice but also holds the promise of transforming bone regeneration in humans.

Developed by scientists at the Korea Advanced Institute of Science and Technology (KAIST), this biomimetic scaffold combines piezoelectric materials and the growth-promoting properties of hydroxyapatite (HAp), a naturally occurring mineral found in bones.

The innovative approach KAIST researchers took, although very much sounding like science fiction, is simply a freestanding scaffold that generates electrical signals when pressure is applied.

These pollutants can originate from many common household products – including vinyl flooring, plastic toys, cleaning products and furniture.

Plastic can change from stretchy and bendy to stiff and rigid—and back.

In a significant leap forward for quantum nanophotonics, a team of European and Israeli physicists has introduced a new type of polaritonic cavities and redefined the limits of light confinement. This pioneering work, detailed in a study published in Nature Materials, demonstrates an unconventional method to confine photons, overcoming the traditional limitations in nanophotonics.

Physicists have long been seeking ways to force photons into increasingly small volumes. The natural length scale of the photon is the wavelength and when a photon is forced into a cavity much smaller than the wavelength, it effectively becomes more “concentrated.” This concentration enhances interactions with electrons, amplifying quantum processes within the cavity.

However, despite significant success in confining light into deep subwavelength volumes, the effect of dissipation (optical absorption) remains a major obstacle. Photons in nanocavities are absorbed very quickly, much faster than the wavelength, and this dissipation limits the applicability of nanocavities to some of the most exciting quantum applications.

Kickstarter has been the graveyard for several high-profile 3D printers. The crowdfunding platform has also introduced numerous subpar 3D printers, alongside some truly outstanding ones. It was on Kickstarter that Formlabs soared to remarkable heights. The platform also brought us the 3D printing pen. There was a period when a new 3D printing project on Kickstarter emerged every week, but both Kickstarter and additive manufacturing (AM) have become considerably less bustling recently. In 2014, things were simpler, as there were far fewer 3D printers available. Now, with the advent of Bambu Labs and sophisticated open-source 3D printers like Prusas, making a significant impact has become much more challenging. NAW 3D is currently attempting to enter the market with a pellet 3D printer on Kickstarter.

The N300 Pellet 3D Printer

NAW3D’s N300 Desktop Pellet 3D Printer boasts an automatic pellet feeding system, with a 100g capacity consumables box and a 2000cm³ material storage space for continuous printing. Additionally, all axes are equipped with linear guides. What’s more, each stage of the printer incorporates double guides. The printer’s nozzles are capable of reaching temperatures up to 300°C. The print head is designed to deposit substantial amounts of material, with printing tracks ranging from 0.2 to 2mm. This capability suggests that the printer can handle both fine details and rapid, large-scale printing tasks.
