Wood‐Derived Nanocellulose‐Biocarbon Fresnel‐Zone Plate Lenses for Sub‐THz Frequency Applications
Advanced Materials Technologies, EarlyView.Wood‐derived nanocellulose and lignin‐based biocarbon were combined to fabricate fully bio‐based Fresnel zone plate (FZP) lenses for sub‐terahertz frequencies. These sustainable FZP lenses exhibit low dielectric loss and high directivity, achieving performance comparable to that of metallic references, and remain functional under environmental stress ...

JAPAN TAPPI JOURNAL, 1997 Recently, one of the greatest concerns of the world wide pulp and paper industries has been organo-chloro compounds discharged from bleach plants which use chlorine based bleaching chemicals. Although there are some debates on toxicities of organo-chloro compounds, we can find a distinct tendency in developing kraft pulp bleaching technologies which ...

Integrated biorefinery for cellulosic ethanol and spherical nanolignin production from coconut waste
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Green coconut waste was subjected to different fractionation methods to obtain integrated lignin nanoparticles and cellulosic ethanol. Pretreatment with gradual addition of dilute sulfuric acid provided a higher structural hemicellulose precursor yield (68.2%).

Applications of Biomaterials in Separators for Secondary Batteries
Carbon Energy, EarlyView.In this review, biomaterial‐based separators are reviewed as sustainable alternatives to conventional polyolefin‐based separators. For 12 different natural polymers, spanning from Protista, Plantae, and Animalia, viable strategies for synthesizing biomass‐based separators are described.

Chemistry – A European Journal, EarlyView.Surface‐bound ferulate phenolate complexes undergo styrene‐like polymerization on alumina, yielding a polymeric carbonaceous layer that progressively transforms into polyaromatic carbon domains with concomitant release of aromatic products, while parallel surface‐assisted decarboxylation produces 4‐vinylguaiacol. ABSTRACT A fundamental understanding of
