Batch experiments were performed to assess (i) the influence of pH, solution amendments, and mineral aging on the rates and products of trichloroethylene (TCE) transformation by iron sulfide (FeS) and (ii) the influence of pretreatment of iron metal with NaHS on TCE transformation rates. The relative rates of FeS-mediated transformation of TCE to different products were quantified by branching ...

This paper investigates high-maturity organic matter-rich shales with high clay mineral contents in the Qingshankou Formation, Gulong Depression of Songliao Basin, at a sub-millimeter scale, using new laminar division method based on XRF data. The influence structure reservoir quality is examined combination geochemistry, mineralogy, and pore structures. Explanatory models are established. Thre...

Urine separation is a promising alternative to present-day waste water management. It can help to manage our nutrient flows in a sustainable way. Currently, techniques are being developed to recycle and treat source-separated urine. These techniques, however, must consider the spontaneous processes that change the separated urine. The initial cause of changes is the contamination with microorga...

This paper presents results of biogeochemical investigation the Holocene organic-rich sapropelic sediments Lake Dukhovoe situated not far from Baikal. The main source organic matter in is phytoplankton, which serves as a barrier where elements are accumulated water and then buried bottom sediments. Microorganisms (e.g., bacteria, micromycete actinomycetes) play significant role decomposition fo...

The 2013M8.3 Okhotsk earthquake involves two primary mechanisms of deep-focus earthquake rupture, mineral phase transformation of olivine to spinel and thermal shear instability. Backprojection imaging of broadband seismograms recorded by the North American and European networks indicates bilateral rupture toward NE and SSE. The rupture paths of the NE segment and other regional M7 earthquakes ...

Somatic embryogenesis is an important biotechnological tool that demonstrates significant benefits when applied to forest tree species; clonal propagation, cryostorage of valuable germoplasm and genetic transformation are among the most promising of its applications. In this chapter, the state of the art of somatic embryogenesis in chestnut (an important economical tree species of the genus Cas...

Solid and aqueous phase Al species are recognized to affect organic matter (OM) stabilization in forest soils. However, little is known about the dynamics of formation, composition and dissolution of organo-Al hydroxide complexes in microbiallyactive soil systems, where plant litter is subject to microbial decomposition in close proximity to mineral weathering reactions. We incubated gibbsite–q...
