TPP+ has been shown to promote the selective mitochondrial uptake of antioxidant compounds driven by the mitochondrial membrane potential [ 62].
While the xylem stream mainly transports water and other inorganic compounds driven by the pull of transpiration from root to shoot, the phloem stream carries organic nutrients from source to sink organs/tissues driven by the pressure gradient [ 4, 5].
In particular, the development of high-strength sheet molding compounds drove wide adoption of compression molding process in automotive and appliance applications.
Compound drives can produce ratios as high as 1,000,000 to 1. Either the circular spline, the flexspline, or the wave generator may be fixed while the other two elements serve as input and output.
The ability to measure efficacy in both the brain and plasma compartments in the transgenic mice allows us to probe whether total or free concentrations of compound drives efficacy.
Another compound behavior driven by physicochemical properties (and heretofore not yet well-understood) is the ability of compounds to permeate into parasite cells and, for intracellular parasites, permeate into both the infected host cells and the parasite.
In Kandahar, Taliban fighters have stormed into a United Nations compound and driven off with vehicles used in an American-financed program that has been disarming millions of land mines left over from the guerrilla war against Soviet forces in the 1980's.
(b), (c) Time-lapse optical images of two different types of compound micromachines driven by rotating uniform magnetic fields [From "Soft micromachines with programmable motility and morphology," Hwang et al., Nat. Commun. 7, 12263 (2016)].
An analysis of packing reveals that the molecular assembly of these compounds is driven by different infinite and finite chains of hydrogen bonds.
Environmental concerns along with the need to develop aliphatic polycarbonate materials free of any toxic compounds have driven scientists to implement macromolecular engineering processes by replacing potentially toxic and carcinogenic metal-based catalysts traditionally used for the ring-opening polymerization of cyclic carbonates by organic compounds.
The export of toxic compounds is driven by proton import catalyzed by the RND proteins [4].
