Nanoparticles seem the future of electronics, at least until the next big thing.

Nano-engineered oxides are very important for the development of next-generation catalysts and microelectronics. Recently, metal exsolution from oxides has emerged as a promising nano-structuring tool to fabricate nanoparticle-decorated oxides. However, controlling the size, density, composition, and location of exsolved nanoparticles remains a challenge, limiting the ultimate performance achievable by these nanostructures.

The following nanoparticle production control was achieved: 1. ion sputtering can controllably reduce the size of surface exsolved nanoparticles down to 2 nm, which are among the smallest values reported in the literature thus far. 2. implanted metal ions can tailor the composition of nanoparticles exsolved both at the surface and in the bulk, providing a convenient and direct way to synthesize exsolved nanoparticles with alloyed compositions. 3. irradiation-induced lattice defects can catalyze the nucleation of nanoparticles, and this enables controlling the density and location of exsolved nanoparticles at specific sample locations using ion irradiation.

LST-1’s discovery of the distant quasar OP 313 at high energies marks a milestone in astronomy, highlighting the telescope’s advanced capabilities in exploring the farthest reaches of the universe.

On December 15, the Large-Sized Telescope (LST) Collaboration announced through an Astronomer’s Telegram (ATel) the detection of the source OP 313 at very high energies with the LST-1. Although OP 313 was known at lower energies, it had never been detected above 100 GeV, making this the LST-1’s first scientific discovery. With these results, OP 313 becomes the most distant Active Galactic Nuclei (AGN) ever detected by a Cherenkov telescope, further showcasing the LST prototype’s exceptional performance while it is being commissioned on the CTAO-North site on the island of La Palma, Spain.

The Nature and Observation of OP 313.

Simulations have shown that a high-speed kinetic weapon weighing 20kg could stop an enemy tank in its tracks.

Ocean thermal energy conversion makes use of the difference in temperatures between the warm surface of the oceans and the deeper cold waters.

AUSTIN (Austin Business Journal) — Tesla Inc.’s growing footprint in the Austin area now includes a sizable facility in Hutto. But what it’s for remains unclear.

The Austin Business Journal visited the 36,000-square-foot site at 200 County Road 199 in the fast-growing industrial hub northeast of Austin in late December. The parking lot was full and a nondescript warehouse-style building was bustling with employees in construction vests and helmets, but there were no signs listing any companies and no clear indications of who was occupying it. The only traces it could be Tesla were a handful of the company’s electric vehicle charging stations out front.

But Elon Musk’s EV manufacturing and clean energy company is linked to the site in state filings, and it has been confirmed by Hutto officials. Tesla’s expansion to Hutto underscores the company’s wide-reaching plans for the region — as far south as San Antonio and, now, as far north as Hutto — as it continues buildout of its multibillion-dollar operation in eastern Travis County. The Hutto site is about 30 miles directly north of its gigafactory, which serves as the company’s headquarters, along State Highway 130.

Earth will be struck today by a coronal mass ejection from a huge solar flare that erupted from the sun on New Year’s Eve.

The New Year’s Eve flare created a CME, a huge bubble of plasma from a region of the sun called the corona, which is equivalent to the sun’s outer atmosphere, and this has an Earth-directed component. Though this massive ejection of plasma will only graze the magnetic bubble surrounding our planet Tuesday (Jan. 2), the magnetosphere, it could trigger a geomagnetic storm that could affect communications and power infrastructure.

The coronal mass ejection CME was hurled into space by an X-class solar flare that burst from the surface of the sun at 4:55 p.m. EST (2155 GMT) on Sunday (Dec. 31). It is the most powerful flare that has happened on the sun during the current solar cycle, solar cycle 25, which began in Dec. 2019. In fact, the flare that ended 2023 with a bang is the largest that has been observed since Sept. 10, 2017, according to the Space Weather Prediction Center of the National Oceanic And Atmospheric Administration (NOAA).

British consumers can will save 500 million pounds over the next decade thanks to the Viking link electricity interconnector.

Viking Link, the world’s longest interconnector, begins operations, linking the UK and Denmark for cleaner, cheaper, and secure energy.

The starting material is generated in excess and available in plenty.

Environmentalists have opposed using crops for jet fuel but there will be no opposition to using a waste that nobody wants.
