We report a prototype CO2 gas sensor based on a simple blackbody infrared source and a spectrally narrow quantum cascade detector (QCD). The detector absorption spectrum is centered at 2260 cm−1 (4.4 μm) and has a full width at half maximum of 200 cm−1 (25 ...
The present invention generally relates to microfluidics, and to spray drying and other drying techniques. Various embodiments of the invention are generally directed to systems and methods for drying fluids contained within a channel such as a microfluidi ...
The dry wear and tribocorrosion behaviour of pulsed plasma treated and non-treated Ni-Cr alloys sliding against alumina at 15 N were investigated by using a reciprocating wear test rig equipped with an electrochemical cell. The pulsed plasma treatment prod ...
Evaporation from porous media is a key process in the hydrologic cycles, waste isolation, biological and food processes and other engineering application. Drying rate and patterns in porous media are strongly influenced by transport properties of the mediu ...
The long term stability and the redox interaction between single walled carbon nanotubes (SWNTs) and photosynthetic reaction center proteins (RCs) purified from purple bacterium Rhodobacter sphaeroides R-26 in the SWNT/RC complex has been investigated. The ...
Three new bimetallic framework compounds, namely, (([Cd3(tn)4][Co(CN)6]2)·5H2O)∞ (1), ([Cd(tn)]3[Cr(CN)6]2)∞ (2), and ([Cu2(tn)2][Ru(CN)6]·4H2O)∞ (3), have been prepared in a very simple manner from the ligand 1,3-diaminopropane (tn), the hexacyanometalate ...
Damage induced by desiccation in clays (i.e. drying shrinkage and cracking) is an issue to be investigated in geo-environmental engineering, especially when the clay is used as a confining barrier for industrial and nuclear waste storage. Dramatic increase ...
This paper presents the results of a comprehensive experimental study of the desiccation of fine-grained soils. Air-drying of initially saturated soil slabs in controlled conditions is investigated, by performing three kinds of tests: free desiccation test ...
Evaporative drying of porous media is jointly controlled by external ( atmospheric) conditions and by media internal transport properties. Effects of different atmospheric potential evaporative demand on observed drying rates were studied in a series of la ...
Catalytic Chemical Vapour Deposition (CCVD) is considered as the most suitable technique for the large scale and low-cost production of multiwalled carbon nanotubes. We have studied the effect of the preparation process, and of the support particle size on ...
