Changes in research focus during the last two decades as reflected in scientific articles in NPPRJ

The changes observed in the research projects of the Nordic Pulp and Paper Research Journal (NPPRJ) during the last two decades, are discussed. One of the research project implied that the same sorption which was used to measure isolation and degraded hemicellulose during 1960s, is studied by enzymatic peeling of the outer layers of the fiber surface. It was also observed that the smaller fractions having a greater influence on the delignification rate is largely because of their higher phenolic content. During the last two decades, the research focus in the pulp and paper field has been increasingly on the development of new products and their end use.
