The basic processes in a cell are simply chemical reactions, but organized in such a way that we get biological behavior, behavior like life, purposeful behavior -- the ability to reproduce yourself, the ability to organize yourself in space and time, the ability to maintain yourself.
In this work, we report the direct fabrication of 3D foam-like carbon materials by ambient pressure chemical vapour deposition on Ni foams, and followed by a simply chemical etching.
The real reason may be that the odors which dogs are trained to detect are simply chemical compositions found in a number of common products.
In addition, the results also proved that the bead-beating step is necessary for activated sludge samples because some phyla, such as Actinobacteria and Nitrospirae, are significantly resistant to the simply chemical cell lysis treatment.
The cytidine is from the crystal structure of vcCNT-7C8C bound to cytidine (for a stereo view of the electron density in the nucleoside-binding site of this structure, see Figure 4 figure supplement 1 ), and the other nucleosides are simply chemical structures in the same orientation as cytidine.
Free market economics, whose rules of supply and demand we so conspicuously ignore in this vast sector of the economy, make simple herbs and plant extracts or simply produced chemicals worth many millions of pounds per tonne.
"I don't simply sell chemicals anymore; I sell the full range of Eastman's services," said Kathy M. Wachala, a principal account supervisor at the Eastman Chemical Company in Kingsport, Tenn., an international manufacturer of plastics, chemicals and fibers with $4.6 billion in sales last year.
Or perhaps the implanted cells simply secreted chemicals that repair damaged neurons or keep them alive.
At a first glance, PCBs seem to be a group of simply structured chemicals.
