The sneaker is made partly from recycled components from old sneakers and water-based solvents.
They are, as might be expected from such complex molecules, not cheap compared with ordinary solvents.
How widely deployable ionic solvents will prove to be in practice remains to be seen.
Solvents are sent the other way, to dilute refined oil that is to be sold in Mexico.
The chemical is normally used for industrial purposes in solvents, petrol and shoe polish and is banned in food.
Every last speck of black paint has to be cleaned from the tubes of the paint-spraying robots with expensive solvents.
Each vial, in turn, could be heated, irradiated, zapped with a laser, filled with solvents, or spun in a centrifuge.
After priming, the body is left to stand again, allowing surplus solvents to escape before the baking process is finished.
The grounds are then filtered out and the solvents separated (to be reused with the next batch of coffee grounds).
The coffee grounds are dried overnight and common chemical solvents, such as hexane, ether and dichloromethane, are added to dissolve the oils.
Not surprisingly, Bakken fracking has active critics who object that the process utilizes diesel fuel and solvents that can cause environmental harm.
Organochlorines are contained in many familiar products, such as in solvents, pesticides, plastics, disinfectants, forms of packaging and bleached pulp and paper products.
At present, the plan is for it to be reprocessed using solvents and chemical processes to separate it into high-level and low-level components.
The emerging technologies involve different solvents, sorbents and membranes as well as methods for extracting carbon from the solvents and regenerating the solvents for reuse.
FORBES: Still Chasing Clean Coal, US Opens Carbon Capture Lab
The air conditioning solvents should also be in good working order.
And, pursuing this idea to its logical conclusion, Elementis Specialties, a British company, has gone one step further designing ionic solvents that themselves act as catalysts.
But ionic solvents should find some immediate uses in existing processes.
The team used inexpensive, environmentally friendly, easy to access materials- a commercially available polymer that can be easily processed from dilute solutions in solvents like water.
It draws out the solvents from the bottom-most layer of polish, leaving all the layers dry and hard, while conditioning cuticles with almond and jojoba oil.
If they have gained mass it could be because the platinum based ingots have absorbed mercury from the atmosphere or hydrogen from the solvents used to clean the ingots.
Those that use photovoltaic collectors are also challenged on environmental grounds because they are manufactured using highly toxic heavy metals, explosive gases and carcinogenic solvents that present end-of-life disposal hazards.
FORBES: Renewable Energy Delusions: Getting A Real Grip On Alternatives
Patiently pausing, Travers replies that organic solvents are used.
"Rothko is difficult in the sense that he painted using lots of different media, which narrows down the choice of solvents that can be safely used on his paintings, " she told the BBC.
The company sees a big market in particular for paints, in which chemical chains of sugar and oil would replace the volatile ketones and oxygenated solvents that vaporize from both oil-based and latex paint.
On the other hand they are eminently recyclable, meaning that they should not have to be replaced that often (which might also endear them to environmentalists, as discarded conventional solvents can be serious pollutants).
These include solvents, pesticides, refrigerants, adhesives and coatings.
However, when he was playing with solvents that might be added to the system to speed the transfer of the dicyclopentadiene to the cracks it is intended to heal, he found a solvent that encouraged the process to work without the ruthenium catalyst.
This molecular mouthful has the rare ability among solvents of being able both to dissolve cellulose and to act as an electrolyte that is, a chemical that can carry current between the electrodes of a battery in the form of charged molecules, or ions.
