The salting-out of lignosulfonates (LSs) follows the Hofmeister series, but different LSs show different susceptibility to salting-out. By comparing results for a large number of LSs from different plant species, pulping conditions, and post-treatmen

In Gordts et al. (2015), we have shown that lignosulfonic acid, a commercially available lignin derivative, possesses broad antiviral activity against human immunodeficiency virus (HIV) and Herpes simplex virus (HSV) by preventing viral entry into su

Eleven different lignosulfonates (LS) and nine different free radical initiators have been tested in different concentrations to study the possibility of forming LS gels. It was found that the initiator must have a potential high enough for oxidizing

There is still a challenging question about how lignosulfonates (LS), such as non-sulfonated lignins, aggregate and disaggregate in solution. In the literature, the reported critical aggregation concentration (CAC) of LS varies by orders of magnitude

The solubility of lignosulfonates (LSs) in water is strongly dependent on other ions present in the water phase. The differences in the solubility might strongly influence the measurements of the physical and chemical properties of the LS molecules.

Several lignin based expanders underwent various physical and chemical tests. The results were compared with life time measurements for batteries with the same expanders. The aim was to gain understanding of the interactions between the expanders and

The expander performs at least five different tasks in the battery. It is a fluidiser for the negative paste. It controls the formation stage of the battery. It controls the shape and size of the lead sulphate crystals formed upon discharge, and thus

A family of eight lignosulphonates produced by Borregaard LignoTech (Norway) is investigated with the aim to determine their efficiency as expanders in the negative plates of SLI lead–acid batteries. The lignosulphonates are introduced during prepa

Seven alkylene aromatic polyimides have been synthesised. FT-IR spectra for the polyimides show small regular changes. This shows that the bulk structure of these polyimides changes in a regular fashion, while SEM pictures do not reveal any differenc
