Methane Partitioning and Transport in Hydrated Carbon Nanotubes

The Journal of Physical Chemistry B, 2003
The well defined shape and size of carbon nanotubes (CNTs) makes them attractive candidates for theoretical and experimental studies of various nanoscopic phenomena such as protection and confinement of molecular species as well as transport of molecules through their interior pores. Here we investigate solute partitioning and transport using molecular

Carbon and nitrogen partitioning in peach/plum grafts

Tree Physiology, 1992
Modifications in root-shoot relationships induced by graft incompatibility were studied in peach/plum graft combinations by means of carbohydrate and nitrogen analyses and isotope labeling. Mobilization of stored carbon, phloem transport of carbon, and mobilization, assimilation and distribution of nitrogen were studied in one compatible peach/plum ...

Partitioning of carbon an SO2-sulfur in a native grassland

Oecologia, 1979
The seasonal assimilation and within-plant partitioning of 14CO2-carbon and 35SO2-sulfur in field plots of mixed-grass prairie was investigated, as was the dry deposition of 35SO2 onto surfaces of dead leaves, litter, and soil, and possible effects of continuous low-level SO2 fumigation on these processes. The proportion of total net-assimilated carbon

Carbon and cofactor partitioning in oilseeds

1990
Abstract Fatty acid biosynthesis in plants occurs only in plastids (Ohlrogge et al. 1979). In the developing endosperm of castor seeds, the biosynthetic pathway from acetate to C18 oleic acid is located in colourless plastids termed leucoplasts (Zilkey and Canvin 1972).

Carbon partitioning in Douglas-fir

1995
Publisher Summary A field gas exchange laboratory, with specially developed branch assimilation chambers operable throughout the year, was installed in a 32-year old Douglas fir stand in the central part of the Netherlands. During 1992, photosynthesis of current year and 1-year-old needles from 5 crown levels was monitored.

Effect of Interfacial Mn Partitioning on Carbon Partitioning and Interface Migration During the Quenching and Partitioning Process

Metallurgical and Materials Transactions A, 2017
A so-called QP-LE model, in which interface condition is assumed to be Local Equilibrium (LE), has been proposed to evaluate the effect of interfacial Mn partitioning on interface migration and carbon partitioning during the Quenching and partitioning process (Q&P) of an Fe-0.3C-3.0Mn-1.5Si (wt pct) alloy.

CARBON PARTITIONING AND RHIZODEPOSITION IN CORN AND BROMEGRASS

Canadian Journal of Soil Science, 1988
Carbon partitioning and rhizodeposition by corn (Zea mays L.) and bromegrass (Bromus inermis Leyss.) were evaluated after 1 and 2 yr of cropping. 14C-labelled CO2 was used as a tracer of assimilated C. Most of the 14C assimilated by corn was translocated to the aboveground plant (nearly 90%), whereas the amounts located above and below ground in ...

Continental-pelagic carbonate partitioning and the global carbonate-silicate cycle

Geology, 1991
A carbonate-silicate geochemical cycle model is developed and used to explore dynamic and climatic consequences of constraints on shallow-water carbonate burial and possible carbon loss to the mantle associated with sea-floor subduction. The model partitions carbonate deposition between shallow-water and deep-water environments and includes carbon ...

Carbon nano partitions for heat dissipation

2011 6th IEEE International Conference on Nano/Micro Engineered and Molecular Systems, 2011
We fabricated carbon nano-partitions (CNPs) which vertically standing on the metal substrates by radio-frequency magnetron sputtering for dissipating heat applications. Considerable enhancement of the conductive heat transfer has been confirmed and the enhancement depends on the spacing density of nano partitions.

Detecting Rapid Changes in Carbon Transport and Partitioning with Carbon-11 (11C)

2019
Noninvasive techniques to measure phloem transport of carbon will be crucial to efforts to engineer improved crop yields, which are highly dependent on carbon partitioning. Phloem, which is buried in the interior of the plant, is highly sensitive to tissue damage.
