PURPOSE:To simplify the identification of the composition of gas, by detecting characteristic common to several kinds of gases such as oxygen, dinitrogen monoxide and nitrogen while a specified gas and residual gas are detected individually to perform a computation using the results of detection. ...
When the chamber did not contain gases (i.e., vacuum), there was only one prominent plasmonic peak in each extinction spectrum of our plasmonic devices. The resonance peaks could be tuned within the 900–2000 cm−1spectral range by varying the ribbon width orVg(Supplementary Figure6). W...
Organic substances such as fibroin, collagen, and cellulose are vital components of organic cultural heritages, carrying significant ancient cultural information. However, their sensitivity to environmental factors leads to heritage deterioration and red
Data for this database was compiled from: hundreds of Material Safety Data Sheets (MSDS) of common industrial and household products; the Hazardous Materials Table from the United States "Code of Federal Regulations" title 49 section 172.101; the National Institute for Occupational Safety and Health...
Primarily driven by prolonged exposure to noxious particles or gases, especially those originating from tobacco smoking, the pathological underpinnings of COPD are complex and varied, involving chronic inflammation, structural changes, and repair processes that affect both the larger airways and the ...
To systematise the consideration of safety issues summarised in Section 2 for the individual ESNII concepts, this Section further discusses the issues and categorises them according to the identified common phenomena with respect to materials – fuel, coolant, structure, and absorber. The objectives...
The Planned CO2 Emission specifies the planned amount of carbon dioxide emitted. The Planned CO2e Emission is the planned CO2 equivalent amount of green house gases emitted. The Actual CO2 Emission specifies the actual amount of carbon dioxide emitted. The Actual CO2e Emission is the actual CO2 ...
Refrigerants - Color Codes Common refrigerants and their color codes. Search Search is the most efficient way to navigate the Engineering ToolBox. Popular internal searches in the Engineering ToolBox Our Mission The Engineering ToolBox provides a wide range of free tools, calculators, and ...
Such pores were then used as etch masks to drill ~10 μm deep nanochannels on the silicon surface by deep reactive ion etching (DRIE) using a combination of SF6/C4F8 gases. Microscale reservoirs were then etched on the backside of the wafers via contact photolithography and DRIE in order ...
applications, it is challenging to detect species with a large quadrupolar interaction at a very low concentration by using this approach. Although oxygen ions in most metal oxides do have a small to mediumCQdue to the small electronegativity values of common metals59, large quadrupolar interactions...
