(showing 31 - 45 of 45)
Carbon Mitigation Measurements
Last Updated Date: 01/22/2015

The global environmental problems caused by emission of CO 2 (global warming, rising sea levels and increased acidity of oceans) must be abated. … more

Establishing Measurement Traceability for Gaseous Mercury Emissions Monitoring
Last Updated Date: 01/20/2015

As a result of the environmental impact of mercury and the neurotoxic risk associated with trophic transfer of methyl mercury to humans, the … more

Assessing NP EHS
Last Updated Date: 01/14/2015

Due to their small size, nanoparticles can enter living organisms in previously unforeseen ways and their immense surface area results in higher … more

Field Parameter Metrology
Last Updated Date: 12/12/2014

Consider the consequences if nearby electronics could interfere with a jet's instruments or cause an automobile to stall. The Field Parameter … more

Fundamental Guided Wave Metrology
Last Updated Date: 12/12/2014

Radio-frequency (RF) waves and microwaves are involved with almost every facet of everyday life. Radio stations, television, wireless devices, … more

Renewable Polymers
Last Updated Date: 09/05/2014

Economic growth, such as that experienced in developed countries over the last century, cannot continue into the next century nor spread to less … more

Femtosecond Laser Frequency Combs for Optical Clocks
Last Updated Date: 08/14/2014

We develop self-referenced mode-locked femtosecond lasers that function as the "gears" of optical clocks. The femtosecond laser clockwork is … more

Smoke Stack Simulator
Last Updated Date: 03/11/2014

Today, inconsistencies between measured CO 2 emissions and emissions calculated from coal consumption are on the order of 10% to 20%. Either a … more

Hyperspectral Image Projector (HIP)
Last Updated Date: 08/02/2013

Detecting climate change with remote sensing instruments, providing state-of-the-art surveillance imagery for security and defense, or getting the … more

Assessing the Internal Structure and Composition of Climatically-Relevant Atmospheric Particles
Last Updated Date: 10/02/2012

Atmospheric particles with long atmospheric lifetimes affect Earth's radiative balance. These particles typically consist of multiple chemical … more

Trophic Transfer of Nanoparticles in a Simplified Invertebrate Food Web
Last Updated Date: 10/02/2012

We demonstrated that carboxylated and biotinylated quantum dots (QDs) can be transferred to higher trophic organisms (rotifers) through dietary … more

International Standards on the Properties of Water
Last Updated Date: 10/01/2012

Researchers in the Thermophysical Properties Division of CSTL played a leading role in the development of several new international standards for … more

Spectroscopic Measurements of Atmospheric Gases for Monitoring Greenhouse Gases
Last Updated Date: 10/01/2012

Climate scientists are developing a new generation of spectrometers for the NASA-sponsored inventory of atmospheric greenhouse gases, most notably … more

Nanoparticle Distribution in the Natural Environment
Last Updated Date: 10/01/2012

Given the substantial differences between nanoparticles (NPs) and typical organic and inorganic environmental contaminants, new methods and … more

Aperture area measurements
Last Updated Date: 11/03/2011
