Buds on Mars

Buds on Mars

Can’t wait for having a cool Bud on Mars?

A commemorative replica of a 1475 beer-stein from Landshut, Germany, (height 7.5”). At that time, the numeral “four” was written as the upper half of the numeral “eight” as shown in the enlargement. Photos by the author.

Why not just take the next rocket to that holiday resort there? Sure, it’s a long journey but the vistas are breath-taking. In fact, not just the vistas, the atmosphere too!

How Do Hand Sanitizers Work?

WASHINGTON  — Alcohol-based hand sanitizers are the ubiquitous little squeeze-bottle heroes of airports and hospitals, our allies during cold and flu season, and supposedly effective against a huge variety of disease-causing viruses and bacteria. But what’s really in hand sanitizers? And is it true that they kill 99.99% of germs, as popular brands claim?

Pulling iron out of waste printer toner

Pulling iron out of waste printer toner
Someday, left-over toner in discarded printer cartridges could have a second life as bridge or building components instead of as trash, wasting away in landfills and potentially harming the environment. One group reports in ACS Sustainable Chemistry & Engineering that they have devised a method to recycle the residual powder in “empty” cartridges into iron using temperatures that are compatible with existing industrial processes.

The art and science of glassblowing (video)

WASHINGTON—If you’ve ever tapped a screen to send a tweet, opted for a glass bottled soda because of taste, or drooled over art glass in a gallery, then your life has been changed for the better by the transparent yet durable combination of sand and simple chemicals we call glass. Reactions visited McFadden Art Glass in Baltimore, Maryland, to learn about the chemistry of this ancient material.

Israeli researchers discover how sponges build glass skeletons that protect them from their environs

Israeli researchers discover how sponges build glass skeletons that protect them from their environment
The technology for forming and shaping glass requires the application of heat at extremely high temperatures. So how do some marine organisms form their own glass “skeletons” in cold water?

That mystery has now been partially solved by a team of Israeli and German scientists. And while the researchers admit that what the marine organisms are doing “is far beyond the abilities of current human technology,” further study may bring us closer to the ability to mimic the mechanism at room temperature in a lab.

Cool textiles to beat the heat

Cool textiles to beat the heat
Air-conditioned buildings bring welcome relief to people coming in from the heat. But creating that comfort comes with a cost to our wallets and the environment in the form of increased energy bills and greenhouse gas emissions. Now researchers report in ACS Nano the development of a new material for clothing that we could one day don as our own personal cooling unit, without any external energy needed to power it.

Jellyfish-inspired electronic skin glows when it gets hurt

Jellyfish-inspired electronic skin glows when it gets hurt
Electronic-skin technologies for prosthetics and robots can detect the slightest touch or breeze. But oddly, the sensors that make this possible do not respond effectively to a harmful blow. Now researchers report in ACS Applied Materials & Interfaces the development of a jellyfish-inspired electronic skin that glows when the pressure against it is high enough to potentially cause an injury.

The chemistry of Hollywood bloodbaths (video)

WASHINGTON — Fake blood is a staple of the Halloween horror film experience, but there’s no one recipe to suit every filmmaker’s needs. The chemistry of fake blood has always been tweaked to create the most realistic experience, or at least the most budget-friendly. From Alfred Hitchcock to Sam Raimi, join Reactions on a Halloween tour of the chemistry of gore:

On the road to fire-free, lithium-ion batteries made with asphalt

Lithium-ion batteries can be found in everything from cell phones to hoverboards, but these power sources have recently made headlines for the fires they have inadvertently caused. To address these safety hazards, scientists report in ACS Nano that they are paving the way to better batteries with a naturally occurring form of asphalt.

Cielo Close to Commercialization with its First Continuous-flow Waste to Renewable Diesel Refinery

Cielo Waste Solutions (CSE:CMC) is delivering on its promise to build its first commercial-grade renewable diesel refinery. Construction is well underway at its High River facility – proving that its proprietary technology will be able to convert multiple different waste feed-stocks,  including landfill waste, into high-grade, renewable diesel has moved the company from demonstration to commercial stage.

Vancouver-based Cielo has extended its private placement offering of units, to accommodate additional subscribers. The private placement has so far raised $2,283,236 for moving its development forward.  A private lender has also signed a Term Sheet with Cielo extending the Company a $3.5 million line of credit. Currently, Cielo and the company are working thru the paperwork to get the credit facility finalized. The 356-litre-an hour continuous flow refinery that Cielo is currently building is a retrofit of a 50-litre-an-hour batch process demonstration plant, which the company and its license provider have been using as a test facility.

Soundlink Micro makes big sound for a tiny package; and The House falls down

First came the Soundlink, then a while later came the Soundlink Mini. So it was probably inevitable that Bose would follow up eventually with this new, micro-sized Bluetooth speaker.

It only makes sense, what with technology’s continuous process of miniaturization and optimization. A computer that used to fill a room is now outclassed by a smart phone and room-filling speakers can now fill rooms from enclosures a fraction of the size of other types of loudspeaker.

With audio, however, the fly in the ointment is bass. Bass frequencies have longer wavelengths than the higher tones and that has traditionally meant you needed those honking big cabinets to reproduce those low frequencies faithfully, while you could get away with smaller speakers for the higher stuff. Hence the proliferation of subwoofers and satellite speakers.

Notes On Tricky Use Of Math

A bat and ball cost $1.10 in total. The bat costs $1 more than the ball. How much does the ball cost?

Almost everyone who reads this question will have an immediate impulse to answer ‘10 cents.’ I surely did. As Dan Gardner says, “It just looks and feels right. And yet it’s wrong. It’s clearly wrong—if you give it some careful thought—and yet it is perfectly normal to stumble on this test. Almost everyone we ask reports an initial tendency to answer ‘ten cents,’ write psychologists Daniel Kahneman and Shane Frederick. Many people yield to this immediate impulse. People are often content to trust a plausible judgment that quickly comes to mind.” 1

Cell phone data coupled with sewage testing show drug use patterns

The drugs people inhale, inject or ingest ultimately end up in some form down the toilet. So scientists have started monitoring drug use through sewage-based epidemiology. But this approach hasn’t taken into account the variation in number of people who add to wastewater in a given area at a given time. Now one team reports in ACS’ Environmental Science & Technology a way to account for commutes and vacations: by tracking cell phone signals.

Toward unbreakable encrypted messages

Chinese researchers recently announced a landmark advancement: They used a satellite orbiting Earth to beam pairs of quantum-entangled photons to two Tibetan mountaintops more than 700 miles apart. This distance blew the previous record out of the water. But according to an article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, this is only the beginning for quantum communication.

Self-folding electronics could enable advanced robotics (video)

As demand grows for more versatile, advanced robotics and other technologies, the need for components that can enable these applications also increases. Producing such components en masse has been a major challenge. But now, in ACS Applied Materials & Interfaces, researchers report that they have developed a way to help meet this need by printing electronics that can fold themselves into a desired shape. Watch a video showing the resulting prototypes here.
