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.

Tetraethyl orthosilicate-containing dispersion coating — water vapor and liquid water barrier properties, TAPPI Journal September 2021
ABSTRACT: An aqueous styrene-butadiene latex dispersion coating containing in-situ processed tetraethyl orthosilicate (TEOS) applied on paperboard demonstrated improved water barrier performance. Coatings containing TEOS equivalent to 0.8% silicon dioxide (SiO2; dry basis) exhibited water vapor performance of < 25 g/m2/day (23°C, 50% relative humidity [RH]) and liquid water barrier performance Cobb 1800 s of < 6 g/m2, when applied as a single-layer 18 g/m2 coating. Cobb 1800 s barrier performance was still good (< 11 g/m2) at coat weights of 7•10 g/m2. The use of filler materials such as kaolin improved the vapor barrier properties of the coating, but this was not critical to the liquid water barrier properties.

A true green cover for industrial waste landfills, TAPPI Journal April 2024
ABSTRACT: Greenhouse gas (GHG) emissions in the United States totaled 5,981 million metric tons of carbon dioxide equivalent (MMT CO2eq) in 2020. Of that, GHG emissions by the pulp and paper sector amounted to 35 MMT CO2eq direct emissions and those by industrial waste landfills summed to 7.4 MMT CO2eq direct emissions. Loss of GHG sinks due to change in land use further contributes to the net GHG emissions. Industrial waste landfills are typically required to comply with certain federal and state regulations, including meeting requirements for final cover systems. Conventional final cover systems have included use of soil covers and/or soil-geosynthetic composite covers. An engineered turf cover provides for an excellent “green” alternative final cover system for industrial waste landfills.This paper discusses various sustainability aspects pertaining to use of an engineered turf final cover, including: (i)significantly low carbon footprint associated with the construction of an engineered turf alternative final coverwhen compared to closure using a traditional or prescriptive cover system; (ii) saving valuable soil and land resourc-es; (iii) saving water resources by reduction in its use during and after construction; (iv) reducing impacts associated with borrow areas; and (v) reducing overall carbon footprint. Further, when using an engineered turf cover, opportunities exist for beneficial reuse of land, including development of solar energy. A brief discussion on the potential fordevelopment of solar energy is included.

Guest Editorial: Research and development in the post COVID-19 era, TAPPI Journal June 2021
Science and technology occupy prominent roles in solving global problems. The ongoing COVID-19 pandemic has reinforced the importance of science regarding decision-making, saving lives, and safeguarding the environment. While information technology (IT) and IT-based tools have garnered much needed attention in the past few decades, other areas such as manufacturing engineering, biotechnology, and pharmaceuticals are finding their right places in gaining public and political support and attention--thanks to COVID-19! Such public attention has highlighted vulnerabilities due to lack of investments in manufacturing and materials engineering, as well as the need for strategic investments in these areas.

From biorefineries to bioproducts: conversion of pretreated pulp from biorefining streams to lignocellullose nanofibers, TAPPI Journal April 2019
ABSTRACT: This study investigates the use of pretreatment and enzymatic hydrolysis side streams and conver-sion to lignocellulose nanofibers. We used a steam-exploded and partial enzymatic hydrolyzed hardwood pulp and an organosolv pretreated softwood pulp to prepare lignocellulose nanofibers (LCNF) via microfluidization. The ener-gies applied on fibrillation were estimated to examine the energy consumption levels of LCNF production. The ener-gy consumptions of the fibrillation processes of the hardwood LCNF production and the softwood LCNF production were about 7040-14080 kWh/ton and 4640 kWh/ton on a dry material basis, respectively. The morphology and dimension of developed hardwood and softwood LCNFs and the stability and rheological behavior of their suspen-sions were investigated and are discussed.

Editorial: Foam forming: Technology of many opportunities, TAPPI JOURNAL August 2019
ABSTRACT: Over the past ten years, the forest sector has faced big changes due to the decreased demand of printing papers and the fast growth in packaging and tissue products. Weekly news on the marine waste problem and global warming have raised public awareness and stimulated increased interest in bio-based materials, chemicals, and fuels.

Evaluating hardness and the S-test, TAPPI Journal March 2019
ABSTRACT: The corrugated industry typically quantifies crush resistance using the Concora corrugated medium test (CMT) on fluted medium or flat crush on combined board. These tests compress the materials until the point of complete failure of the flutes. Combined board elastically resists crushing forces until a certain point, the hardness of the structure, while additional load causes permanent damage and deformation. This study investigates how hardness can be measured directly from a load curve collected during CMT (or flat crush) testing and how it varies throughout the North American paper supply. It also explores how hardness corre-lates with the values obtained from the newly developed S-test. This new test method deserves further study as a potentially more appropriate specification for crush resistance of corrugated medium.

Relating bending stiffness measurements across various free span lengths, TAPPI Journal August 2020
ABSTRACT: Bending stiffness should be an intrinsic property of a material, so it is puzzling that the TAPPI Standard Test Method T 836 “Bending stiffness, four point method” specifies span lengths when testing different types of corrugated fiberboard. These specified spans often limit the samples that can be measured with this method. To better understand the relationship between bending stiffness and span length, we performed measurements on a range of materials at different spans. The results provide a practical tool enabling comparison of bending stiffness measurements made at various span lengths. Additionally, this note discusses several areas that could serve as the foundation for more fundamental work exploring the bending behavior of corrugated board.
