types of chemical bond between carbon atoms in a hydrocarbon molecule.
This technique, published in the journal Nature, not only uses existing plant waste but consumes large amounts of CO2 and could be applied to
other types of chemical manufacturing as well — a boon to our increasingly CO2 - saturated atmosphere.
«The interesting thing is that though there are two different
types of chemical processes happening in a single material, they appear to be working synergistically, and are able to do that at a lower temperature.»
To determine whether solid nanoparticle catalysts exhibit a related
type of chemical communication, a team led by Peng Chen of Cornell University scrutinized nanoparticles made of either gold or palladium as the materials mediated various types of model catalytic reactions.
Eye cream can also easily get in your eye on accident and if you're using an all - natural product then you don't have to worry about
what type of chemicals are getting in there!
But, in the interests of consistency, we shall only invent new objects when we can not escape from doing so; usually, it is sufficient slightly to modify the description of our previous objects, e.g., when we modify the definition of the atom to accommodate it to new observations about radioactivity or atom - smashing, or new
types of chemical combination.
You get a sense EcoLogic Solutions Inc. is a different
type of chemical company the moment you walk into its Brooklyn Navy Yard headquarters and see walls made out of plants and furniture fashioned from old doors and reclaimed materials.
And their detailed understanding of the underlying reaction mechanism should enable the LMU researchers to apply this relatively simple way of controlling molecular motions to other
types of chemical switches.
The incredibly strong magnetic fields surrounding white dwarfs — aged stars with the mass of our sun or greater that have collapsed to the size of a planet — could generate
unusual types of chemical bonds, a new study suggests.
There are two different
types of chemical groups that comprise glass surfaces, he said: silanol (SiOH) groups that are generally hydrophilic (water - loving), or siloxane (SiOHSi) groups that are typically water - repellant.
The creation of triangulene demonstrates a new
type of chemical synthesis, says Philip Moriarty, a nanoscientist who specializes in molecular manipulation at the University of Nottingham, UK.
The researchers say the molecular details of wax biodegradation require further investigation, but it's likely that digesting beeswax and polyethylene involves breaking down
similar types of chemical bonds.
«Frog neurons, like those in people and other animals, receive the same
type of chemical inputs, but it's been a major challenge to understand how they work together to enable to enable the neurons to compute the length of a sound,» Rose says.
Eschewing sole reliance on structural analysis, the team used two different
types of chemical analyses: time - of - flight secondary ion mass spectrometry and infrared reflectance spectroscopy.
The beta - sheets are connected to each other by hydrogen bonds, which are among the
weakest types of chemical bond — far weaker, for example, than the covalent bonds found in most organic molecules.
Several types of chemical modifications of the five major histone protein families give rise to a complex «histone code» that signals the transcriptional machinery to turn genes on or off.
† Boswellia serrata extract is so powerful that today it's considered comparable to NSAID pain relievers (the
leading type of chemical anti-inflammatory medications).
Finally, we have the specific
type of chemical most notoriously found in personal care products — parabens.
Air fresheners (including plug - in air fresheners) contain the same
types of chemicals found in scented candles and pose the same safety concerns.
Researchers at Oregon State University have discovered novel compounds produced by certain
types of chemical reactions — such as those found in vehicle exhaust or grilling meat — that are hundreds of times more mutagenic than their parent compounds which are known carcinogens.
The scientists catalogued the genes of numerous bacteria from the Deepwater Horizon oil spill to figure out how microbes gobble up the complex mix found in oil, which consists of as many as 1,000
types of chemical compounds.
Along with data from the few studies like Yokelson's, Wiedinmyer used guidelines for calculating trash burning emissions produced by the Intergovernmental Panel on Climate Change to determine how much waste was being generated and burned, what exactly was in that waste, and
what types of chemicals were likely generated.
• Verification of finding and describing any sort of safety intrusions • Complete understanding of keeping essential reports and organizing compulsory reports • Knowledge of the safe utilization of various types of chemicals
Studies of farm laborers who worked with the compound showed rates of certain cancers double to eight times the national average, but those exposures were intermittent and not exclusive, because workers handle
many types of chemicals.
For instance, the team uncovered a
new type of chemical - sensing tuft cell (which helps alert the immune system to infection or other forms of injury) that displayed markers previously thought to be exclusive to immune cells and which may help sound the alarm about allergens and invading parasites.
This work contributes to our understanding of the
specific types of chemicals that influence our water resources,» he said, noting that he believes this broad method will one day become routine in monitoring.
In schizophrenia, excessive oxidation — which involves the
same type of chemical reaction that causes metal to corrode into rust — is widely thought to cause inflammation and cellular damage.
There is also the «cocktail effect» that occur when different chemicals that might be safe to use for humans mix together with
other types of chemicals and together they will make up a toxic mix that can be harmful for your health.
