Food science professor’s ‘instant ice cream’ gains patent
https://news.cornell.edu/stories/2020/05...ins-patent

RELEASE: One moment, you have a bowl of creamy chocolate liquid. Then, in an instant, it’s ice cream. Forget hocus-pocus: This is physics and engineering. In Syed Rizvi’s laboratory, a prototype machine – featuring a newly patented process – uses supercritical carbon dioxide to dish out instant vanilla ice cream.

After a five-year application process, the U.S. Patent and Trademark Office awarded Patent No. 10,624,363 B on April 21 to Syed Rizvi, professor of food science engineering, and Michael E. Wagner, Ph.D. ’15. And just like that, the world got a little sweeter.

With Rizvi and Wagner’s newly patented process – where pressurized carbon dioxide does all the work – anyone can make any ice cream at any time. “Of course, you’ll need the liquid ice cream mix,” Rizvi said. “The mix can be made commercially, locally or you can make it at home. It’s very simple, and this machine converts the mix into a scoop of ice cream in about three seconds.”

In the traditional method of making ice cream, the dairy-based mix flows through a heat-exchanging barrel, where ice crystals form and get scraped by blades. With this new method, highly pressurized carbon dioxide passes over a nozzle that, in turn, creates a vacuum to draw in the liquid ice cream. When carbon dioxide goes from a high pressure to a lower pressure, it cools the mixture to about minus 70 degrees C – freezing the mixture into ice cream, which jets out of another nozzle into a bowl, ready to eat.

Instant ice cream can be served right on the spot, all without the challenges of commercial transportation “cold chains,” in which the product must be frozen and maintained at minus 20 degrees Celsius. To guard against failing spots in the cold-temperature transportation chain, commercial ice cream makers add stabilizers and emulsifiers.

“Consumers today want a clean product,” Rizvi said. “They don’t want undesirable ingredients thrown into it.”

What’s more, Rizvi said, the cold chain requires a lot of energy. But if you could make ice cream without stabilization ingredients, commercial entities could avoid the cold chain altogether. The device can take any liquid and give it frozen features. “You can make a slushy out of soft drinks,” he said, while noting that the new process is suited for on-demand and point-of-use applications like vending machines, parlors and home use. “You can convert water into carbonated ice instantly, too. Any liquid drink that can be partially frozen can be used.”

Cornell’s Center for Technology Licensing is currently exploring licensing opportunities.



Microsoft lays off journalists to replace them with AI
https://www.theverge.com/2020/5/30/21275...placements

INTRO: Microsoft is laying off dozens of journalists and editorial workers at its Microsoft News and MSN organizations. The layoffs are part of a bigger push by Microsoft to rely on artificial intelligence to pick news and content that’s presented on MSN.com, inside Microsoft’s Edge browser, and in the company’s various Microsoft News apps. Many of the affected workers are part of Microsoft’s SANE (search, ads, News, Edge) division, and are contracted as human editors to help pick stories.

“Like all companies, we evaluate our business on a regular basis,” says a Microsoft spokesperson in a statement. “This can result in increased investment in some places and, from time to time, re-deployment in others. These decisions are not the result of the current pandemic.”

While Microsoft says the layoffs aren’t directly related to the ongoing coronavirus pandemic, media businesses across the world have been hit hard by advertising revenues plummeting across TV, newspapers, online, and more... (MORE)

Is there a lot more possible uses of the ice cream maker? Could the principle of it revolutionize basic refrigeration, replace ozone depleting refrigerants and save millions of dollars as well as save the environment. Plenty CO2 to go around. Would my tongue stick to -70°C ice cream?

Probably wouldn't even cause an ice burn unless the appendage was left in replenished ice cream for an extended period. Metal conducts heat away from the tongue far faster than a substance that contains an ingredient which is a biological product itself.

Unfortunately, nothing seems really unique about what this ice cream maker utilizes unless it's the "plumbing design" between the input and output nozzles. Something surely had to be modestly different to garner a patent, anyway. I doubt "we're going use this to approach to make instant ice cream instead of instant ice cubes" would have been enough to escape encroachment on an existing device using similar principles and equipment. 

There is this recent development (below) for helping to save energy, the environment, and assisting garbage scavengers of Manila in being able to afford refrigeration:

Nanoparticles can make home refrigeration more accessible for low-income households
https://www.eurekalert.org/pub_releases/...052920.php

INTRO: Power consumption of a home refrigerator can be cut by 29% while improving cooling capacity. Researchers replaced widely-used, but environmentally unfriendly, R134a refrigerant with the more energy-efficient R600a. They dosed R600a with multi-walled carbon nanotube (MWCNT) nanoparticles. Drop-in refrigerant replacement in the field by trained technicians is possible, says an engineer from the University of Johannesburg.

This test of nanoparticle-dosed refrigerants is a first of its kind and recently published in Energy Reports, an open-access journal. The results can help make home refrigeration more accessible for low-income families.

R134a is one of the most widely-used refrigerants in domestic and industrial refrigerators. It is safe for many applications because it is not flammable. However, it has high global warming potential, contributing to climate change. It also causes fridges, freezers and air-conditioning equipment to consume a lot of electrical energy. The energy consumption contributes even more to climate change.

Meanwhile, a more energy-efficient refrigerant can result in much lower electricity bills. For vulnerable households, energy security can be improved as a result. Improved energy economy and demand-side management can also benefit planners at power utilities, as cooling accounts for about 40% of energy demand...
