"If you can understand how rust is going to form, then you can at least anticipate what kinds of effects it will have, and develop materials that can better handle the chemical reaction happening on their surface," said Taylor.
In a report published in the journal Geophysical Research Letters, the scientists argued that "a large portion" of the sulfur in the haze was the result of a chemical reaction between formaldehyde and sulfur dioxide released by burning coal.
But Dr. Gregg, who praised the research as a "great example of the scientific method," worried that the team did not look at the precise chemical makeup of the Venusian atmosphere, including sulfur, which might affect the chemical reaction.
London startup MEL Science is putting a high-tech twist on them, with virtual reality and augmented reality content that takes kids on a virtual tour inside a chemical reaction, right after they conduct an experiment in the real world.
Adgate said a 911 call was placed by an employee at the restaurant, initially for "a chemical explosion," but when first responders arrived at 369 Washington St., they determined it was a chemical reaction likely started by the cleaning materials.
The exact workings of the system, including the conditions under which it will trigger, are up to the automaker, but the general idea is that the chip triggers a small explosion, similar to the chemical reaction that inflates an airbag.
As countries seek low emissions energy sources to power vehicles, homes and industry, Japan is betting heavily on becoming a "hydrogen society" despite the high costs and technical difficulties of a process that creates electricity from a chemical reaction of fuel and oxygen.
In fact, both tests are not always perfectly accurate: the test strips can go off if they're not stored correctly; common drugs like Tylenol can interfere with the chemical reaction; and microorganisms and tissue can gunk up the sensor in a continuous monitor.
First, the researchers identified all the natural proteins that could be activated by a specific type of light to create a chemical reaction that kills pathogens, according to Young Kim, a materials scientist at Purdue University and co-author of the paper.
A series of tests run by Jackson's team revealed that the aluminous tobermorite crystals were created from a chemical reaction: when seawater flooded through the cracks in the concrete, it reacted with a mineral known as phillipsite found naturally in the volcanic rock.
With bike's range limited by the size of the hydrogen tank, Pragma is also working on a bike that will convert plain water into hydrogen aboard the bike, using a chemical reaction between water and aluminum or magnesium powder to produce hydrogen gas.
That shape determines what the protein does: acting as a channel, say, to admit a chemical into a cell; or as an enzyme to accelerate a chemical reaction; or as a receptor, to receive chemical signals and pass them on to a cell's molecular machinery.
Fuel cells generate electricity through a chemical reaction using hydrogen as a fuel and platinum as a catalyst, but comprise only a fraction of the electric vehicle (EV) market even though they allow vehicles to travel much longer distances between charges than battery powered cars.
For instance, one approach called electro-geochemistry — a simple chemical reaction to turn CO21 into bicarbonates we can dump in the ocean — might manage to consume 2900 to 13 gigatons, depending on availability of renewable energy sources for the electricity it needs to function.
If those were to end up in landfills, they'd run the risk of going through a process called "thermal runaway," which is basically a chemical reaction in the battery that can cause it to heat up, potentially to the point of burning or exploding.
Portugal-based startup CRIAM (which stands for chemical reaction and image analysis for mobility) hopes to change that with its "PCT-patented" portable tool to determine the correct blood type while in an ambulance or on site in an emergency in fewer than 3 minutes.
Bioluminescence, in which an organism gives off light via an internal chemical reaction, such as a firefly, and biofluorescence, in which an organism takes in UV light and then re-emits at a lower energy level, like some sharks, is a fairly common biological process on Earth.
They emit green light, a result of nearly the same chemical reaction that illuminates the belly of a firefly or the skin of a squid, only the resulting light is constant in the mushroom, not on-demand or reactive as in some insects or marine animals.
They had worked through different formulations before landing on one that combined freebase nicotine with benzoic acid (the patent covers a range of acids) that set off a chemical reaction, producing a nicotine salt liquid that reduced the harshness and allowed a higher rate of nicotine.
Back in 2014, a research team led by Marie D. Jackson of the University of California at Berkeley showed how the recipe for Roman concrete—a mixture of volcanic ash, lime, and seawater combined with a volcanic rock aggregate—produced a chemical reaction that resulted in super-strong concrete.
More often than not Pálmason creates scenes that have some sort of surprising reveal or capper: a slap to the face; a bottle of clear liquid instantly turning dark due to a chemical reaction or by magic; a mouth pried open as it's forced to drink the noxious hooch.
The tears in onions are caused by a chemical reaction that occurs when an onion is cut, and in the case of the Asda Sweet Red, the farmer that developed the onion selectively bred onions with lower pungency levels in order to create an onion that won't make people cry.
"Because the cause of the incident is still being investigated, we are deferring to first responders for any further details on the potential cause of the chemical reaction and the status of Team Members and others who were in the restaurant at the time of the incident," the spokesperson added.
