Long term trend of chemical oxygen demand in Saroma-ko Lagoon, Japan; possible effects of climatic warming [PDF]

open access: yes, 2008
A trend of shortening duration of ice coverage has been reported in many rivers, ponds and lakes around the world due to climatic warming. The shortening will have much influence on organic production due to the greater supply of light intensity and ...

Dynamic hydrogen bonds promote C–H functionalization driven by Cl− anion

open access: yesTetrahedron Chem, 2022
Most of studies for hydrogen bonds focus on the static model especially between two polar atoms. In contrast, introducing the third polar atom may emerge the competitive hydrogen bonds, which would represent a distinct perspective to perturb the ...

Chemical and spectroscopic analysis of olive mill waste water during a biological treatment [PDF]

open access: yes, 2007
The treatment of olive mill waste water was studied on the laboratory scale. Physico–chemical analyses showed the final products had a mean pH of 5.4 without neutralisation and 5.7 when lime was added to the process.
