Editorial: Advancing the Digital Twin paradigm — From network mechanics to functional paper physics, TAPPI Journal March 2026
This Special Paper Physics Issue of TAPPI Journal serves as a critical bridge between the phenomenological observations shared at the last International Paper Physics Conference in Wuppertal, Germany, and the rigorous quantification required to realize the “Digital Twin” paradigm. This paradigm involves the creation of a virtual dynamic representation of a process that acts as a real-time counterpart of the actual one. We are particularly indebted to Jaan-Willem Simon of the University of Wuppertal, whose leadership was pivotal in translating the conference’s academic rigor into this scholarly collection.

Estimating dose and interaction of X-rays with cellulose-based fibrous materials using micro-computed tomography, TAPPI Journal March 2026
ABSTRACT: Micro-computed tomography (ìCT) has a reputation as a nondestructive analysis method. Unfortunately, this leads to the common misconception that radiation damage of the sample does not play a role. With the increased use of ìCT in laboratory-based machines, more and more cellulose-based materials are studied. In this paper, we show with three examples that radiation damage is important in dry and wet paper and in viscose fibers. In an attempt to quantify radiation damage, we came up with a workflow that enables researchers to predict the X-ray dose within a laboratory-based ìCT machine. This gives researchers the possibility to quantitatively judge the influence of radiation damage on each measured sample. While one cannot extend the measured doses from one machine to another, one can still apply the work flow presented in this study to any ìCT setup. In this way, it is possible to minimize radiation damage by choosing the best parameters in a ìCT for obtaining perfect data with no or little radiation damage.
