Newer #dielectric fluids and #powerelectronics now allow #electrostaticmotors to be better at some applications than their electromagnetic peers.

> The main advantage of electrostatic motors is their reduced critical materials use. In particular, electrostatic motors don’t require copper windings or any rare earth magnets which are getting more expensive as demand grows for electrically-powered machines.

Gratifying meetings of the Committee on Electrical Maintenance, creating the second draft of NFPA 73, Electrical #Inspection of Existing #Dwellings. One change for 2025 adoption: no more grandfathering for receptacles that need #GFCI protection. I hadn't expected us to go this far, but when someone buys a home, this will protect them. Another is more a camel's nose: an Annex reminder re #bonding past #dielectric fittings or plastic tubing interrupting metal #plumbing.

If you recognize the name Ajinomoto, you’re probably surprised to hear it plays a critical role in the chip sector:

the company is better known as the world’s leading supplier of #MSG seasoning powder.

In the 1990s, Ajinomoto discovered that a by-product of MSG made a great insulator, and it has enjoyed a near monopoly in the niche material ever since.

But Ajinomoto doesn’t make any of the other parts that go into chips.
In fact, the insulating materials in chips rely on dispersed supply chains: one layer uses materials from Ajinomoto, another uses material from another company, and so on, with none of the layers optimized to work in tandem.

The resulting system works okay when data is being transmitted over short paths, but over longer distances, like between chips, weak insulators act as a bottleneck, wasting energy and slowing down computing speeds.

That’s recently become a growing concern, especially as the scale of AI training gets more expensive and consumes eye-popping amounts of energy.

#Ajinomoto #dielectric #film #laptops #data #centers #Thintronics #CHIPS #Science #Act

For 30 years, a single Japanese company called #Ajinomoto has made billions producing #dielectric #film.
Competitors have struggled to outdo them, and today Ajinomoto has more than 90% of the market in the product, which is used in everything from #laptops to #data #centers. 

But now, a startup based in Berkeley, California, is embarking on a herculean effort to dethrone Ajinomoto and bring this small slice of the chipmaking supply chain back to the US.
#Thintronics is promising a product purpose-built for the computing demands of the AI era
—a suite of new materials that the company claims have higher insulating properties and, if adopted, could mean data centers with faster computing speeds and lower energy costs. 

The company is at the forefront of a coming wave of new US-based companies, spurred by the $280 billion #CHIPS and #Science #Act, that is seeking to carve out a portion of the semiconductor sector, which has become dominated by just a handful of international players.

But to succeed, Thintronics and its peers will have to overcome a web of challenges—solving technical problems, disrupting long-standing industry relationships, and persuading global semiconductor titans to accommodate new suppliers.

`Here we report a theoretical and experimental framework for the force behaviour in generic solid/liquid-dielectric #multilayer stacks independent of #actuator design and solely based on their #dielectric properties. We use this model to develop #materials-based solutions, which rely on matching the bulk charge relaxation rates of the constituent dielectrics, for a variety of soft actuator systems: tunable #lenses, artificial #muscles and #haptic #devices.`

apparently the mechanism was that the α radiation lowers the #dielectric breakdown of the combustion mixture. #radon did the same thing to the air in Marie Curie's lab

Since the advent of smartphones & the #IoT, devices have become essential.

A new way of using a smart material -known as #dielectric elastomer- might open the door to a whole new range of possibilities.

The secret is that they do many things at once👉https://europa.eu/!Vdb6rn
