Silicone Recycling

While consumer silicone products are often selected to replace single-use plastics, reducing the amount of waste generated overall, they too eventually must be disposed of - so what happens to the waste? Although silicone is a polymer, it has a silicon, oxygen based backbone, not carbon based like most polymers and plastics known. As such, silicone will often find its way into landfills when recycled by consumers, as it cannot be recycled with the other polymers in the stream. Silicone is not biodegradable, and takes a considerable length of time to break down.

Silicone can be recycled at designated recycling centers, though typically through mechanical means, resulting in a 'downcycled' product. Apart from consumer recycling, overall recycling rates of silicone is expected to steadily increase over the coming decade.

The result of the material analysis of Sammy's mystery rubber-like thing is in, and it's mostly made of silicone rubber based on polydimethylsiloxane (aka dimethicone) with a tiny bit of metal soap (they gave calcium stearate as an example, but I think it could be any metal soap).

I tried to google all of these terms, but not a whole lot came up with the combination, so I'm still rather stumped about what object(s) he could have eaten, how often he did or how long ago that was.

The best result was cable sheathing from medical equipment, but that seems rather unlikely? 😅 At least we can rule out something organic, which is a start.

Will do some more research in any case, but if anyone happens to have an idea please let me know!

Researchers develop non-contact touch sensors for robotics

A radical new type of touch sensor for robotics and other bio-mimicking (bionic) applications is so sensitive it works even without direct contact between the sensor and the objects being detected. It senses interference in the electric field between an object and the sensor, at up to 100 millimeters from the object. The researchers at Qingdao University in China, with collaborators elsewhere in China and South Korea, describe their innovation in the journal Science and Technology of Advanced Materials. Electronic skins have become a crucial element in bionic robots, allowing them to detect and react to external stimuli promptly. This can allow robotic systems to analyze an object's shape, and, if required, also to pick it up and manipulate it.

Instructions for use of Silanol-terminated polydimethylsiloxane

Silanol-terminated polydimethylsiloxane is a commonly used organosilicon compound with many applications. Here are the instructions for its use:

Solubility: Silanol-terminated polydimethylsiloxanes are usually colorless to pale yellow liquids with good solubility. It can be dissolved in many organic solvents, such as toluene, ether and acetone, etc. An appropriate solvent can be selected according to specific needs.

End-capping reactions: Silanol-terminated polydimethylsiloxanes can be end-capped by reacting with silanols such as methylsilanol. This capping reaction can be accomplished by adding a small molecule silanol capping agent, usually in excess.

Surface treatment agent: Silanol-terminated

polydimethylsiloxane can be used as a surface treatment agent to improve surface properties and interfacial wetting. It can provide ultra-low surface tension and enable it to form a uniform coating on the surface of many materials (such as glass, ceramics, metals, etc.).

Release Agents: Silanol-terminated polydimethylsiloxanes can be used as mold release agents to prevent sticking and sticking. It can be applied to the mold surface of rubber, plastic, composite materials, etc., so that there is good separation between the mold and the product.

Functional additives: Silanol-terminated polydimethylsiloxanes can also be used as functional additives to improve the performance of coatings, adhesives, sealants, etc. It can increase the weatherability, chemical resistance and stain resistance of coatings.

Soft Support Can Make Unexpectedly Stable Glass - Technology Org

New Post has been published on https://thedigitalinsider.com/soft-support-can-make-unexpectedly-stable-glass-technology-org/

Soft Support Can Make Unexpectedly Stable Glass - Technology Org

A team of researchers from Penn and the Brookhaven National Laboratory find a new way to manufacture stable glass.

Glasses are ubiquitous materials found in building materials, beverage containers, soft electronics, and mobile phone screens. A process known as aging creates naturally dense and rigid glass. It involves a slow transformation that can take place over millennia to hundreds of millions of years and is marked by the gradual densification and rigidification of a liquid-cooled below its melting point.

Illustration by Nathi Magubane/University of Pennsylvania

However, in 2007 researchers found that stable glasses can also be produced by condensing the material from the vapor phase, using a process called physical vapor deposition. Vapor deposition allows molecules that have just arrived at the surface to pack better, producing better-aged glasses. 

Now, a team of researchers led by Zahra Fakhraai of the University of Pennsylvania’s School of Arts & Sciences, in collaboration with scientists at the Brookhaven National Laboratory, have discovered a method to further expedite this aging process, redefining the fundamental principles that have guided the formation of stable glass. Their findings were published in the journal Nature Materials.

“What we discovered, rather paradoxically, is that, by using a soft, more flexible substrate during our vapor deposition process, we can make more rigid and denser glasses than previously made,” Fakhraai says. “These findings offer a new way to precisely engineer glass films and pave the way for making durable materials much faster.”

The discovery came about serendipitously when Peng Luo, a postdoctoral researcher in the Fakhraai Group, was encouraged to experiment with soft substrates for glass deposition, primarily as a curiosity, “to see if softer substrates would cause damage to the material,” he says. “But what we saw was glass that exhibited properties as if it aged for many millions of years, far exceeding what can be seen on methods using traditional rigid substrates.”

Luo explains that prior studies used deposition rate and substrate temperature to control the assembly of the surface molecules after they land on the substrate. At appropriate temperatures, the slower the rate of deposition, the more time the landed molecules will have to adjust themselves towards a more stable structure before they become buried and “frozen” by the incoming molecules. 

“It’s basically a “self-assembly” of the surface molecules in a way determined by their own mobility at a certain temperature, and we don’t have all that much control over how slow we can deposit,” he says. “Our finding that a soft substrate can make the deposited glass film denser indicates that substrate elasticity can affect the assembly process of the surface molecules, and, therefore, this can be used as a new dimension to control the structure and properties of glass films in a much larger range which was not accessible before.” 

By deploying soft substrates such as polydimethylsiloxane, the team showed that it is possible to significantly accelerate stable glass formation, crafting a material with a 2-2.5% higher density than conventional liquid-quenched glasses and as much as 1% larger than any other reported stable glass.

Luo adds that another noteworthy finding is that the molecule they deposited is only a nanometer in length; however, during deposition the surface equilibrium processes can be affected by the soft substrate over a considerable distance, measured to be about 200 nanometers. This distance is notable because it far exceeds what would be expected based on current glass theories, presenting a challenge to existing understanding.

“This effect can be likened to playing a game of telephone in an auditorium packed with 200 people but somehow, quite mysteriously, the message is communicated perfectly without disruption” Fakhraai says. “The soft substrate’s influence over such a large distance suggests a form of long-range communication or interaction on the surface, which is not fully understood and something we’re interested in exploring in future research.”
