- Automated sorption balances are widely used for characterizing the interaction of water vapor with hygroscopic materials. These instruments provide an efficient way to collect sorption isotherm data and kinetic data. A typical method for defining equilibrium after a step change in relative humidity (RH) is using a particular threshold value for the rate of change in mass with time. Recent studies indicate that commonly used threshold values yield substantial errors and that further measurements are needed at extended hold times as a basis to assess the accuracy of abbreviated equilibration...AuthorsSamuel L.

- The primary objective of this study was to evaluate and compare the broad suitability of young Eucalyptus grandis W. Hill ex Maiden (EG), E. amplifolia Naudin (EA), Corymbia torelliana (F. Muell.) K.D.Hill & L.A.S. Johnson (CT), and Populus deltoides W. Bartram ex Marshall (PD) for making MDF by evaluating the basic wood properties of MDF produced from defibrillated Short Rotation Woody Crops (SRWC). Fast-growing EG, EA, CT, and PD may be deployed in SRWC systems in the lower Southeastern USA, especially in Florida. To evaluate these species for possible use as medium density fiberboard...AuthorsDonald L. Rockwood, Jerrold E. Winandy, Neil GribbinsKeywordsSourceBook chapterYear2024
- Lignin is a promising precursor to produce graphene materials due to its high carbon and aromatic contents. Upgrading lignin into graphene materials has gained significant interests as it offers a cost-effective and sustainable route to produce high-performance carbon materials. This review provides a comprehensive overview of the state-of-the-art technologies on lignin to graphene materials with a focus on thermal catalytic and photothermal upgrading. The applications of lignin-derived graphene materials and the perspectives for mass production of such graphene materials are also discussed.AuthorsHanwen Zhang, Qiangu Yan, Yucheng Peng, Zhiyong Cai, Caixia WanKeywordsSourceJournalYear2024
- Single Atom catalyst (SAC), a new frontier in heterogeneous catalyst design has evolved as a novel strategy to resolve the cost puzzle hindering the commercial scale applications of benchmark noble metal catalysts in various technologies. Downsizing expensive noble metal catalyst to atomically active centers have simultaneously reduced cost via enhanced atom utilization and maximized their catalytic activity and selectivity. However, taking full advantages of this novelty requires stabilization on appropriate support materials that provide adequate anchoring sites, promote strong metal...AuthorsPanesun Tukur, Frank Tukur, Yirong Mo, Qiangu Yan, Chaochao Dun, Jianjun WeiKeywordsSourceJournalYear2024
- Environmental pollution, particularly from heavy metals and toxic elements, poses a significant threat to both human health and ecological systems. While various remediation technologies exist, there is an urgent need for cost-effective and sustainable solutions. Biochar, a carbon-rich product derived from the pyrolysis of organic matter, has emerged as a promising material for environmental remediation. However, its pristine form has limitations, such as low adsorption capacities, a relatively narrow range of pH adaptability which can limit its effectiveness in diverse environmental...AuthorsNeda Arabzadeh Nosratabad, Qiangu Yan, Zhiyong Cai, Caixia WanKeywordsSourceJournalYear2024
- Fresh and clean water is highly demanded throughout the world. To effectively address the need, nanomaterials enabled nanotechnology has been explored as a means of more efficient, reliable, and environmentally friendly approach towards water treatment practices. One concern in adopting nanomaterials is how to retrieve them from water body to avoid secondary contamination. In this work, the earth abundant and sustainable wood, e.g., basswood, was selected and carbonized into porous carbon as host skeleton, and metal-organic frameworks (MOFs), e.g., MOF-199 with extremely high surface area,...AuthorsAkhter Zia, Manish Neupane, Aidan McGlone, Rui He, Ruikun Xin, Yifeng Liu, Qiangu Yan, Jinwu Wang, Ling Li, Zhiyong Cai, Pei Dong, Yingchao YangSourceJournalYear2024
- Soy is considered one of the most promising natural materials for manufacturing wood adhesives due to its low cost, high protein content, and ready availability. However, more cost-effective ways of improving its wet shear strength are needed to achieve wider market acceptance. Protein adhesive wet strength depends on the use of (typically expensive) crosslinking additives as well as the processing/denaturation of the protein. It has been commonly stated in the literature that protein denaturation leads to higher bond strength by activating the surface and exposing the reactive groups....AuthorsHeikko Kallakas, Nayomi Z.

- During the past two decades, tremendous progress has been made in the development of biodegradable polymeric materials for various industrial applications, including human and veterinary medicine. They are promising alternatives to commonly used non-degradable polymers to combat the global plastic waste crisis. Among biodegradable polymers used, or potentially applicable to, veterinary medicine are natural polysaccharides, such as chitin, chitosan, and cellulose as well as various polyesters, including poly(ε-caprolactone), polylactic acid, poly(lactic-co-glycolic acid), and polyhydroxyalka...AuthorsMagdalena Broda, Daniel J.

- Incorporating cellulose nanofibers into concrete has a positive impact on its strength. This study evaluated how cellulose nanofiber-reinforced concrete affected the economic and environmental performance compared to conventional concrete. The estimated minimum selling price per unit mass (m3) per unit compressive strength (MPa) of cellulose nanofiber-reinforced concrete mixture is 12 % lower ($2.52/m3/MPa) compared to the minimum selling price of conventional concrete mixture ($2.87/m3/MPa). However, when comparing the minimum selling price on a mass basis, the cellulose nanofiber-reinforc...AuthorsNaveenkumar Rajendiran, Troy Runge, Richard Bergman, Prakash Nepal, Nithya Nair, Warda AshrafSourcejournalYear2024
- Research on new conservation treatments for historical wood requires considerable amounts of appropriate wood material, which is hard to acquire. Thus, we produced biologically and chemically degraded model wood that could be used as a representative material in future research on consolidating agents. Using chemical composition determinations, we found that fungal decay targeted mainly polysaccharides, while alkaline treatment mostly reduced hemicelluloses and lignin content. X-ray and neutron scattering showed that all decayed samples had increased disorder in microfibril alignment and...AuthorsMagdalena Broda, Nayomi Z.
