This study was designed to test the hypothesis that bacterial phosphate uptake is controlled primarily by the chemical environment
McDermott co-authored a Science paper on the investigation, which concluded that magnetite retains its stable structure in spite of these irregularities thanks to a mechanism that redistributes cations in response to the surrounding chemical environment
. This observation sheds new light on the single-atom action that drives processes such as heterogeneous catalysis, hydrogen production and drug delivery, where iron oxides already have an important role.
They can detect the chemical environment
and they can 'feel' their physical surroundings using ultrasensitive sensors.
In the presence of a chemical environment
, including air and water, which are aggressive chemical environments
to some materials, the environment is absorbed and penetrates the micro-structure of the polymer, when a tensile stress is present.
Earlier this year, a report by Mike Brown, an astronomer at the California Institute of Technology, and Kevin Hand from NASA's Jet Propulsion Laboratory, said Europa's salty ocean beneath its frozen surface suggests there is a chemical exchange between the ocean and surface, making it a rich chemical environment
Soldiers need to train with JSLIST because that will be what protects them In a chemical environment
. I see units still training with the old battle dress overgarment MOPP gear.
The textbook introduces graduate students to the function and structure of estuarine ecosystems, looking in turn at the physical, geological, and chemical environment
; primary producers including microbes; consumer organisms; and emergent holistic properties of estuaries.
"The streams in Iceland are all very similar, in terms of their physical and chemical environment
, but maintain very different temperatures to each other all year round," the study's lead author, Dr Daniel Perkins was quoted as saying.
Contributors describe their work in integral equation theories (including bridge functions and applications to classical fluids), the chemical environment
of ionic liquids (including the links between liquid structure, dynamics and solvation), counter-ion condensation in nucleic acids, physiochemical applications of scanning electrochemical microscopy, certain shapes of centrosymmetric cyclic dimers involving weak hydrogen bonds, and time-resolved photoelectron spectroscopy of nonadiabatic dynamics in polyatomic molecules.
Chronic overproduction of the compound changed the chemical environment
in the cell from oxidative to the opposite, a reductive state.
"Apart from supplying and installing the transformers, switchgear and cables, the site itself was a challenge with construction being carried out in a hazardous chemical environment
