Complex influence of temperature on oxalic acid anodizing of aluminium
Electrochimica Acta, 2019Two-step aluminium anodizing is widely used to prepare oxide films with a highly-ordered porous structure through the whole thickness. It can be realized solely at relatively low values of current density in the kinetic anodizing regime that makes this ...

A one-step acidification strategy for sewage sludge dewatering with oxalic acid.
Chemosphere, 2019Sewage sludge dewatering is an efficient approach to reduce the volume of sludge for the subsequent disposal. In this study, a novel one-step acidification sludge dewatering method was developed with using oxalic acid as a conditioner.

13C chemical shielding in oxalic acid, oxalic acid dihydrate, and diammonium oxalate
The Journal of Chemical Physics, 197513C chemical shielding tensors in three oxalates were investigated in order to determine the effects of protonation and conformation changes on the tensor elements and their orientations. The experimental results, together with those in the accompanying paper [R. G. Griffin and D. J. Ruben, J. Chem. Phys.
