Editorial: The road to sustainable packaging: New research on aqueous barrier coating, TAPPI Journal November 2022
ABSTRACT: This TAPPI Journal Special Coating Issue looks at hot topic research being done in coatings for paper and paperboard. We can feel the “earth shifting” in paper and paper-board packaging due to the strong call by consumers and brand owners for more sustainable and environmentally friendly options. This is the first TAPPI Journal Special Coating Issue to highlight efforts within the paper coating community to produce more sustainable packaging.

Fiber-based characterization of pulp refining, TAPPI Journal September 2022
ABSTRACT: Fiber development in pulp refining can be characterized by three parameters: number of impacts on pulp, N; energy per impact, I, and bar force on fibers, F. These parameters enable comparisons of radically different refining conditions; determination of intensity for hardwoods and softwoods; assessment of effect of bar width on fiber shortening; and predictions of tensile strength increases.

Continuous digester rapid thinning, TAPPI Journal June 2024
ABSTRACT: Carbon steel continuous digesters built after the early 1980s are fully stress relieved, so stress corrosion cracking has been less of a concern. However, these newer digesters were designed to run modified cooking processes that have turned out to be much more corrosive than those running with conventional cooking. This corrosion is mainly associated with softwood digesters and appears to be flow related. Average corrosion rates of 40 mil/year are possible on the exposed shell between the wash and extraction screens. The corrosion patterns are visually distinct from surfaces in the upper digester and below the wash screens. This paper goes into practical detail on where it occurs, the causes, visual identification, inspection planning and results evaluation, and finally, how to mitigate this damage, which consists of applying a corrosion resistant barrier. Some discussion on dealing with general corrosion throughout the digester is included.

Editorial: Looking forward, looking back, TAPPI Journal January 2022
ABSTRACT: Much like 2020, 2021 was another year of remarkable highs and lows delivered by the COVID-19 pandemic. Vaccines, variants, and infection surges altered the way we behaved personally and professionally last year. As we move into 2022, we are now grappling with health and business concerns from the omicron variant that has overwhelmed hospitals in some areas and contributed to a global supply chain crisis. The ability to adjust has once again become a key skill in adapting to our shifting “new normal.”

Editorial: Agility and adaptation in a dynamic business world, TAPPI Journal January 2021
ABSTRACT: As we move into 2020, it's interesting to look back at the research topics that were covered in TAPPI Journal (TJ) the previous year. Members of the TJ editorial board organized diverse special issues on lignin, coating ,forming, and diverse papermaking and biorefinery topics, which are discussed in the following sections.

Editorial: Transform presentations to TAPPI Journal research papers by following basic steps, TAPPI Journal August 2024
ABSTRACT: Very often, important research findings are communicated in presentation form at industry conferences like those TAPPI holds. While this is a great way to highlight your work, it has some limitations when compared to a peer-reviewed TAPPI Journal paper. Presentations are limited to a specific event, while publishing papers in a peer-reviewed journal means that your work becomes part of scientific literature that is available to a broader audience. Also, a research paper allows for a more detailed explanation of the methods, data, and conclusions than the time-constrained format of a presentation.

Real-time monitoring of bubble size distribution in a foam forming process, TAPPI JOURNAL August 2019
ABSTRACT: Foam forming is an intricate option to lessen fiber flocculation and to get better energy and water efficiency when making fiber-based products. Developed during the 1970s, this approach has recently received renewed attention, mainly because it also offers possibilities to widen the fiber-based product portfolios with novel and more valuable products. In addition to air content, bubble size is the most important property of foam. Foam quality control is essential for building real-world foam forming processes. In this work, we show how bubble size can be monitored with direct optical imaging in real time in real process conditions, and how such analysis helps adjust foam quality and discover process faults in foam forming.

Editorial: ”Didn’t know we knew that” • Rediscovering the fundamentals, TAPPI Journal April 2022
ABSTRACT: Access to today’s extensive electronic information archives is certainly an amazing feat of technology. Nonetheless, it can sometimes be difficult to find pulp and paper industry process-specific resources that are easily digestible and tailored to help us in our day-to-day work.
