Crop residues reshape microbial community composition and function across acidic soils via interactions between carbon chemistry, soil pH and nutrient availability

open access: goldGeoderma
There is a significant gap in understanding how crop residues with varying carbon-to-nitrogen (C/N) ratios mitigate soil acidification in acidic soils, particularly considering the complex interplay between soil C chemistry, pH, nutrient dynamics, and ...

Hyperbranched phosphorus flame retardants: multifunctional additives for epoxy resins [PDF]

open access: yes, 2019
We successfully synthesized multifunctional P-based hyperbranched polymeric flame retardants (hb-FRs) with varying oxygen-to-nitrogen (O : N) content and characterized them via 1H and 31P NMR and GPC.

Phase Chemistry of Tank Sludge Residual Components [PDF]

open access: yes, 1999
Experiments began with ''neutralization'' of iron (III)-aluminum nitrate solutions by addition of sodium hydroxide at room temperature. The final pH of most experiments was approximately 13.7. The samples were neutralized in PP or HDPE bottles that were then submerged in a water bath and aged at 90 C for up to 120 h.
