Distribution and sources of polycyclic aromatic hydrocarbons in soils from Shengli Oil Field, China
Soil and Water Research, 2018 The concentrations of 16 polycyclic aromatic hydrocarbons (PAHs), which are on the United States Environmental Protection Agency (US EPA) priority pollutant list, were studied in ten different soil samples from Shengli Oil Field, China.

EAS Publications Series, 2011 In dense molecular clouds, the birthplace of stars and planets, interstellar atoms and molecules freeze onto extremely cold dust and ice particles. These ices are processed by ultraviolet light and cosmic rays forming hundreds of far more complex species, some of astrobiological interest.

Advanced Engineering Materials, EarlyView.Collagen hydrolysate is evaluated as a sustainable binder for MgO‐C refractories. Its thermally induced cross‐linking and gas release lead to expansion and cracking in large bricks, but tailored batches with lignin, recyclates, or fine graphite improve the gas release while thermal treatment and stability.

Advanced Functional Materials, EarlyView.This study presents a versatile approach to harnessing miscible aqueous domains, enabling liquid‐in‐liquid compartmentalization using a barrier formed in situ rather than bulk immiscibility. The barrier forms upon the complexation of multifunctional nanoparticles and ligands at the contact boundary of aqueous phases.

Effects of root exudates on the sorption of polycyclic aromatic hydrocarbons onto biochar
Environmental Pollutants & Bioavailability, 2019 The effect of oxalic acid on phenanthrene sorption was varied from that on pyrene sorption. 1.0 mg L-1 of oxalic acid inhibited phenanthrene sorption, whereas 20, 50 and 100 mg L-1 of oxalic acid enhanced the sorption.
