The character of gas analysis is based on the nature of the molecular arrangement in the gaseous state. In this, the molecules are relatively far apart and evenly fill the available space. Their motion is random and interactions are rare, such that clustering does not occur. Consequently, ...
Gas flow behavior in porous media with micro- and nanoscale pores has always been attracted great attention. Gas transport mechanism in such pores is a complex problem, which includes continuous flow, slip flow and transition flow. In this study, the mic
Membrane separation is a commonly used method of nitrogen production, the principle is based on different gas molecules, the rate of penetration of specific membrane materials to complete the oxygen and nitrogen separation.Advantages:the equipment has a compact structure, covers a small area and is ...
The obtained results demonstrated the importance of microstructure control of sensing layers for improving the sensitivity to large size molecules like volatile organic compounds (VOCs). 展开 关键词: TiO 2 nanotube VOC Porosity control Porous film Hydrothermal treatment ...
sI comprises dodecahedral (512) and tetrakaidecahedral ( 51262) cages, whereas sII is composed of 5 12 and hexakaidecahedral ( 51264) cages. sH has a large icosahedral (51268) cage in its unit cell and can encapsulate larger guest molecules. Natural hydrocarbon gases can...
The vapor species react, forming intermediate and product molecules and clusters that quickly grow to nanosized ceramic particles. On the other hand, under certain conditions, a small number of the droplets, particularly with large initial sizes, escape from the spray boundaries and become ...
, the corresponding value of δ13DCH4is in the interval of − 250‰ – −150‰ and − 400‰ – −250‰, respectively33. Of note, the hydrogen atom of CH4comes from water molecules, and the above-mentioned two objects can be represented by Eqs.7and8as follow41...

The D3 band is located near 1500 cm−1 and represents sp2 hybrid amorphous carbon structure, including small organic molecules and fragmented functional groups. The attribution of the D4 band is still controversial, and its peak is usually around 1200 cm−1, but it is generally to be ...
It was found that the dilatational modulus is not only determined by the interactions between spread molecules (which depend on the surface density) but that the structure of the spread monolayer also plays an important role. 展开 DOI: 10.1021/la0017375 被引量: 73 ...
