This is the first attempt to directly correlate fiber collapse and entrapped or hard-to-remove (HR) water content through DSC, TGA and SEM. Freeze-drying and oven drying were individually investigated for influence on collapse. SEM of the fibers at different moisture contents show that irreversible collapsing begins as entrapped water departs the fiber surface. The removal of HR water pulls cell walls closer due to strong capillary action which overwhelms the elastic force of the fiber lumen which results in partially or fully irreversible collapse. The initial moisture content and refining intensity were found to regulate HR water content and consequently played a vital role in fiber collapsing.}, journal={CARBOHYDRATE POLYMERS}, publisher={Elsevier BV}, author={Salem, Khandoker Samaher and Naithani, Ved and Jameel, Hasan and Lucia, Lucian and Pal, Lokendra}, year={2022}, month={Nov} } @article{salem_naithani_jameel_lucia_pal_2021, title={Lignocellulosic Fibers from Renewable Resources Using Green Chemistry for a Circular Economy}, volume={5}, ISSN={["2056-6646"]}, url={https://doi.org/10.1002/gch2.202000065}, DOI={10.1002/gch2.202000065}, abstractNote={The sustainable development of lignocellulose fibers exhibits significant potential to supplant synthetic polymer feedstocks and offers a global platform for generating sustainable packaging, bioplastics, sanitary towels, wipes, and related products. The current research explores the dynamics of fiber production from wood, non‐wood, and agro‐residues using carbonate hydrolysis and a mild kraft process without bleaching agents. With respect to carbonate hydrolysis, high yield, and good coarseness fibers are attained using a simple, low‐cost, and ecofriendly process. Fibers produced using a mild kraft process have lower Klason lignin, carboxyl content, surface charges, and higher fiber length, and crystallinity. Eucalyptus fibers show the highest crystallinity while softwood carbonate fibers show the lowest crystallinity. Hemp hurd fibers contain the highest concentration of hard‐to‐remove water, and thus, suffer maximum flattening visualized by the microscopic images. The relatively high yield sustainable fibers with versatile properties can provide a significant economic benefit since fiber is the dominant cost for producing various bioproducts to meet society's current and future needs.}, number={2}, journal={GLOBAL CHALLENGES}, author={Salem, Khandoker S. and Naithani, Ved and Jameel, Hasan and Lucia, Lucian and Pal, Lokendra}, year={2021}, month={Feb} } @article{debnath_salem_naithani_musten_hubbe_pal_2021, title={Soft mechanical treatments of recycled fibers using a high-shear homogenizer for tissue and hygiene products}, volume={6}, ISSN={["1572-882X"]}, url={http://dx.doi.org/10.1007/s10570-021-04024-0}, DOI={10.1007/s10570-021-04024-0}, journal={CELLULOSE}, publisher={Springer Science and Business Media LLC}, author={Debnath, Mrittika and Salem, Khandoker Samaher and Naithani, Ved and Musten, Evan and Hubbe, Martin A. and Pal, Lokendra}, year={2021}, month={Jun} } @article{naithani_tyagi_jameel_lucia_pal_2020, title={Ecofriendly and Innovative Processing of Hemp Hurds Fibers for Tissue and Towel Paper}, volume={15}, ISSN={["1930-2126"]}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-85078956694&partnerID=MN8TOARS}, DOI={10.15376/biores.15.1.706-720}, abstractNote={An innovative approach for preparing hemp fibers from hemp hurds for use in tissue and towel grades of paper is described. Hemp hurds are a low value by-product of industrial hemp processing that are generally used for animal bed litter. Tissue paper was fabricated from hemp hurd fibers by following three pulping processes: autohydrolysis (hydrothermal), sodium carbonate-based defibration, and high yield kraft pulping, and benchmarked against hardwood pulp. To meet industrial standards, hardwood and hemp pulp fibers were mixed at a dry mass ratio of 75:25, from which tissue paper sheets were prepared. Desirable tissue paper properties, such as water absorption, burst resistance, softness, and tensile strength (dry and wet), were measured and compared. Characterization of morphological and chemical properties of tissue handsheets was conducted with SEM and time-of-flight-secondary ion mass spectrometry (ToF-SIMS). The combined kraft pulped hardwood and autohydrolyzed hemp pulp fibers displayed improvements in tensile index, burst resistance, and softness of tissue handsheets compared to only kraft hardwood pulp handsheets without adversely impacting water absorption. Hardwood fibers showed a sparse distribution of surface lignin compared to hemp fibers using the same defibration. This technology can lead to a variety of eco-friendly tissue paper products that are not only highly energy efficient, but avoid harsh chemical processing.}, number={1}, journal={BIORESOURCES}, author={Naithani, Ved and Tyagi, Preeti and Jameel, Hasan and Lucia, Lucian A. and Pal, Lokendra}, year={2020}, month={Feb}, pages={706–720} } @article{agate_tyagi_naithani_lucia_pal_2020, title={Innovating Generation of Nanocellulose from Industrial Hemp by Dual Asymmetric Centrifugation}, volume={8}, ISSN={2168-0485 2168-0485}, url={http://dx.doi.org/10.1021/acssuschemeng.9b05992}, DOI={10.1021/acssuschemeng.9b05992}, abstractNote={Among nanobiomaterials, cellulose nanofibrils (CNF) possessing intrinsically appealing fiber dimensions on the nanometer scale and biocompatibility feature arguably the greatest potential for a var...}, number={4}, journal={ACS Sustainable Chemistry & Engineering}, publisher={American Chemical Society (ACS)}, author={Agate, Sachin and Tyagi, Preeti and Naithani, Ved and Lucia, Lucian and Pal, Lokendra}, year={2020}, month={Jan}, pages={1850–1858} } @article{naithani_lucia_jameel_hart_2020, title={Soybean peroxidase treatment of ultra-high kappa softwood pulp to enhance yield and physical properties}, volume={19}, ISSN={["0734-1415"]}, DOI={10.32964/TJ19.9.437}, abstractNote={The working hypothesis serving as basis for this study is that pulping to a higher kappa number will produce a higher yield pulp, and then treating that pulp with a surface reactive lignin peroxidase to ablate surface lignin will increase specific bonding area. In the present case, the working hypothesis was modified so that soybean peroxidase (SBP) works like lignin peroxidase to modify surface lignin on high-kappa, high-yield softwood pulps to facilitate enhanced fiber-to-fiber bonding such that the resulting paper strength is similar to the lower kappa soft-wood pulp generally used to make linerboard. Soybean peroxidase is actually a plant peroxidase that exhibits lignin peroxidase-like activity. It is not a lignin peroxidase derived from white rot fungus. The current work did show a significant improvement in pulp yield (62.2% vs. 55.2% yield for a 103-kappa control linerboard grade sheet), while treatment with SBP showed that tensile, burst, and STFI properties of the pulp were improved, although more convincing data needs to be obtained.}, number={9}, journal={TAPPI JOURNAL}, author={Naithani, Ved and Lucia, Lucian and Jameel, Hasan and Hart, Peter W.}, year={2020}, month={Sep}, pages={437–443} }
