In Situ Production of Branched Glycerol Dialkyl Glycerol Tetraethers in a Great Basin Hot Spring (USA)

Frontiers in Microbiology, 2013
Branched glycerol dialkyl glycerol tetraethers (bGDGTs) are predominantly found in soils and peat bogs. In this study, we analyzed core-bGDGTs and polar (P-) bGDGTs after hydrolysis of polar fractions using liquid chromatography-atmospheric pressure ...

The chemometric approach to identification of residual oil contamination at former primitive asphalt pavement plants; pp. 410–430 [PDF]

Oil Shale, 2019
This study investigated polycyclic aromatic hydrocarbons (PAHs) and hydrocarbon oil index (HOI) pollution in the soil on the territories of two former primitive asphalt pavement plants (APPs) in Estonia. The standard quantitative methods for the chemical

Effect of irrigation with magnetized and ionized water on yield, nutrient uptake and water-use efficiency of winter wheat in Xinjiang, China

Agricultural Water Management
Magnetization can alter hydrogen bonds among water molecules, leading to changes in water physicochemical properties, and ionization can use frequencies to break down polymers for better solubility.

Atmospheric amines and ammonia measured with a chemical ionization mass spectrometer (CIMS) [PDF]

Atmospheric Chemistry and Physics, 2014
We report measurements of ambient amines and ammonia with a fast response chemical ionization mass spectrometer (CIMS) in a southeastern US forest and a moderately polluted midwestern site during the summer.

Impulse Grounding Resistance Reduction Measures for Transmission Line Towers in Desert, Gobi, and Barren Land Regions

Energies
The high soil resistivity in desert, Gobi, and barren land regions limits the lightning current dissipation capability of conventional needle-type grounding electrodes, thereby increasing the lightning-related risk to transmission lines.
