Using CHN microanalysis to determine soil health

Exeter Analytical reports on how its Model 440 CHN Microanalyser is being used to precisely determine the percentage Carbon and Nitrogenin soil samples



Determining carbon, hydrogen and nitrogen percentage in liquid samples

Analysis can be done without sacrificing accuracy or precision and without the need for expensive liquid autosamplers



Routine CHN microanalysis of difficult sample types

Warwick Analytical Service (WAS) has developed a range of CHN microanalysis methodologies allowing them to routinely produce precise and accurate percentage Carbon, Hydrogen and Nitrogen data from a range of difficult samples.




Easy-to-understand introduction to CHN microanalysis

CHN microanalysis is a key analytical technique for determining whether or not a sample is pure



New Czech – Chinese GD Nanodec R&D center inaugurated in Beijing

In the framework of a Czech – Chinese cooperation project in the field of nanofiber applications, a GD Nanodec research and development center was inaugurated in Future Technology City on 6 December 2013.



Rising CO2 Levels: Not a toothless threat

Rising carbon dioxide levels in the atmosphere are having a catastrophic effect on microscopic marine life, according to top marine scientists at the University of St Andrews.



Study reveals significant leakage of carbon stored on land to rivers, lakes, estuaries and coastal regions

New research suggests that human activity could be increasing the movement of carbon from land to rivers, estuaries and the coastal zone



Analyzing soil samples for percentage carbon, hydrogen and nitrogen

Application note 51 from Exeter Analytical Inc. illustrates how the Carbon, Hydrogen and Nitrogen (CHN) content of soil samples can be precisely and reproducibly determined using their Model 440 Elemental Analyzer.



New carbon dioxide emissions model

With the help of new models for a prescribed atmospheric carbon dioxide concentration, scientists from all over Europe have now calculated for the first time the extent to which the global carbon dioxide emissions must be reduced to halt global warming.



Carbon sequestration

The idea to sequester carbon is gaining support as a way to avoid global warming. For example, the European Union plans to invest billions of Euros within the next ten years to develop carbon capture and storage.



Plankton plays role in ocean carbon fixation

Carbon fixation by phytoplankton in the open ocean plays a key role in the global carbon cycle but is not fully understood.



Echinoderms contribute to global carbon sink

The impact on levels of carbon dioxide in the Earth's atmosphere by the decaying remains of a group of marine creatures that includes starfish and sea urchin has been significantly underestimated.



Sponges recycle carbon to give life to coral reefs

Coral reefs support some of the most diverse ecosystems on the planet, yet they thrive in a marine desert. So how do reefs sustain their thriving populations?



Carbon nanotubes can affect lining of the lungs

A new study shows that inhaling these nanotubes can affect the outer lining of the lung, though the effects of long-term exposure remain unclear.



A recipe for controlling carbon nanotubes

Nanoscopic tubes made of a lattice of carbon just a single atom deep hold promise for delivering medicines directly to a tumour, sensors so keen they detect the arrival or departure of a single electron.



Carbon nanotubes could make efficient solar cells

Using a carbon nanotube instead of traditional silicon, researchers have created the basic elements of a solar cell that hopefully will lead to much more efficient ways of converting light to electricity than now used in calculators and on rooftops.



Nanotechnology: Harnessing carbon nanomaterials promise

Two nanoscale devices harness the potential of carbon nanomaterials to enhance technologies for drug or imaging agent delivery and energy storage systems.



Environmental effects of carbon nanoparticles

A new study raises the possibility that flies and other insects that encounter nanomaterial 'hot spots,' or spills, near manufacturing facilities in the future could pick up and transport nanoparticles on their bodies.



A Genome May Reduce Your Carbon Footprint

Acquiring cheap genome sequence data can improve the quality of feedstocks used to create biofuels, according to a new study published in The Plant Genome.
