  • Optimization of a microwave-assisted extraction procedure for the determination of selected alkyl, aryl, and halogenated phenols in sewage sludge and biosolids

    A microwave-assisted extraction method for the determination of 15 alkyl, aryl, and halogenated phenols in sewage sludge and biosolids samples was developed and optimized. The effects of solvent, temperature, time, moisture content, acid, and number of extractions on the recovery of phenols were evaluated. Results indicated that extraction solvent had the greatest impact on the recovery of all ...

  • PureAire Oxygen Analyzer for 3D Printers: How Argon is used and Why O2 Detection is Required

    Thanks to new technologies, the 3D printers that have been used to create plastic three-dimensional objects can now print metal. Titanium 3D printing is possible thanks to a technique called DMLS, or Direct Metal Laser Sintering. While the potential to use titanium 3D printing is groundbreaking for many industries, the new advances could pose a health hazard if volatile gases used in the printing ...

  • Analysis of key trends and drivers in greenhouse gas emissions in the EU between 1990 and 2014

    1 GHG emissions in 2014 compared to 2013 1.1 Summary (last year) Total GHG emissions (excluding LULUCF) decreased by 185 million tonnes, or 4.1% compared to 20132 to reach their lowest level in 2014 (4282 Mt CO2 eq.). This significant decrease in emissions in 2014 came with an increase in GDP of 1.4 %. This resulted in a lower GHG-emission intensity of GDP in the EU ...

  • An Overview Of STI Group’s Core Industrial Services

    It takes numerous specialists and engineers to manage industrial plants and facilities and keep them running smoothly, efficiently, and safely. Some of these individuals may only be required during special projects or industrial turnarounds when speed and efficiency are of the essence to get the plants back into production as quickly as possible. Other times industrial services are required on a ...
