aNitrogen is an inert gas, but at a high temperature can and file, calcium, magnesium and oxygen. Nitrogen can be liquefied, condensed into liquid nitrogen. Nitrogen so can be applied to oil industry is suitable for physical reasons, its chemical properties, a guaranteed source, low cost. 氮...
Particles and trace gases were measured with a set of well characterized instruments that have been deployed aboard aircraft in previous campaigns3,30. The CAS29mounted under the wing of the Falcon was used during ECLIF1 to measure ice particle number concentrations and the size distribution in th...

To add on to her initiatives to exploit Arctic contexts to understand the interaction of bioaerosols and the atmosphere, Jessie (as PI) and Chris are constructing a proposal to the Arctic Natural Sciences program to conduct filter-based and real-time measurements on the upcoming joint US/SE su...
liquid C. gas D. plasma E. none of the above It has been said, "There are forces of attraction between molecules in all chemical systems." Which of the following experimental observations supports this statement? a. Gases ...
reuse and recycle of the water masses that evapotranspired from plants, because the majority of the water is lost via the ventilation process to the outside area and furthermore most of the water vapor of greenhouses is mainly condensed at the inner walls, making impossible its collection proce...
Ship engines in the open ocean and Arctic typically combust heavy fuel oil (HFO), resulting in light-absorbing particulate matter (PM) emissions that have been attributed to black carbon (BC) and conventional, soluble brown carbon (brC). We show here tha
Research from Oxford University calls us to reconsider how behaviours may spread through societies of wild animals, and how this might provide new insights into human social networks. Our social connections to one another, whether it be online or in real life, give rise to our 'social networks...
The use of NH3, rather than ND3, (which would normally be used for powder neutron diffraction) meant that the incoherent scattering of the hydrogen within the gases present in the reaction chamber could be correlated to how much ammonia had decomposed. For both the ammonia synthesis and ...
Tannins can be divided into three major groups: proanthocyanidins (PAs, syn. condensed tannins), hydrolysable tannins (HTs), and phlorotannins. From these, PAs and HTs possess large structural variability; PAs are oligo- and polymers formed of two or multiple flavan-3-ol units, while HTs ...
