Factories, the chief innovation of the industrial revolution, are cathedrals of productivity, built to shelter specialized processes and encourage the division of labor. Adam Smith, who illuminated their function on the first page of The Wealth of Nations, offered the celebrated example of a pin factory: "I have a seen a small manufactory… where ten men only were employed, and where some of them consequently performed two or three distinct operations. But the benefits of factories suggest their limitations. They are not reprogrammable: To make different products, a factory must retool with different machines. Thus, the first product shipped is much more expensive than the next million, and innovation is hobbled by need for capital expenditure and is never rapid.
Nevada is home to America's only major source of lithium. For a generation, the cutting edge of American innovation lived in the garages and office parks of Silicon Valley. Our brightest minds forged their master works in the digital ether, breakthrough after breakthrough propelling humankind into the Information Age. Today, a new high-tech rush is underway. This one is spurred by the grim reality of climate change and the ascendance of clean energy.
The deal, according to the companies, will provide Desktop Metal with up to $575 million in gross proceeds and create a combined company with a post-transaction equity worth up to $2.5 billion. Under the terms of the deal, Trine will contribute $300 million via the merger, adding to $275 million secured by Desktop Metal via a $10 per share PIPE from Miller Value Partners, XN, Baron Capital Group, Chamath Palihapitiya, JB Straubel, and HPS Investment Partners. Burlington, Massachusetts-based Desktop Metal is also touting the deal as part of an effort to consolidate the additive manufacturing industry, which is expected to be worth over $140 billion by 2030. Desktop Metal will list on the New York Stock Exchange under the ticker symbol "DM". "We are at a major inflection point in the adoption of additive manufacturing, and Desktop Metal is leading the way in this transformation," said Desktop Metal CEO Ric Fulop.
Permanent magnets are generally produced from solid metals or alloys. Less dense compositions involving lighter elements tend to demagnetize well below room temperature or under modest applied external fields. Perlepe et al. now report that chemical reduction of a low-density chromium-pyrazine network produces a magnet that remains stable above 200°C and resists demagnetization with 7500-oersted coercivity at room temperature. The straightforward synthetic route to the material shows promise for broad exploration of potential applications. Science , this issue p.  Magnets derived from inorganic materials (e.g., oxides, rare-earth–based, and intermetallic compounds) are key components of modern technological applications. Despite considerable success in a broad range of applications, these inorganic magnets suffer several drawbacks, including energetically expensive fabrication, limited availability of certain constituent elements, high density, and poor scope for chemical tunability. A promising design strategy for next-generation magnets relies on the versatile coordination chemistry of abundant metal ions and inexpensive organic ligands. Following this approach, we report the general, simple, and efficient synthesis of lightweight, molecule-based magnets by postsynthetic reduction of preassembled coordination networks that incorporate chromium metal ions and pyrazine building blocks. The resulting metal-organic ferrimagnets feature critical temperatures up to 242°C and a 7500-oersted room-temperature coercivity. : /lookup/doi/10.1126/science.abb3861
For the longest time, it was weirdly difficult to play Solid Snake's early outings on PC. The original Metal Gear was released for the MSX2 computer and then, a few years later, MS-DOS and Commodore 64. Few people still own this kind of hardware, so your options were emulation or one of the game's many home console releases, including the popular NES port from 1987. The first two Metal Gear Solid titles, meanwhile, were released on PC but never available through digital storefronts like Steam. Thankfully, there's now a convenient way to buy all three on PC: GOG.com.
