ESTUDO DA ADIÇÃO DA LIGNINA KRAFT NAS PROPRIEDADES MECÂNICAS DOS BRIQUETES DE RESÍDUOS DA INDÚSTRIA MOVELEIRA [PDF]
, 2017 In order to improve global effectiveness of energy production, a strategy is the model of bio-refineries in which all the components of biomass are totally used to produce a range of products with aggregated value. The kraft lignin is one of the products

Physiological roles of lignins - tuning cell wall hygroscopy and biomechanics. [PDF]
New PhytolSummary Lignins constitute the second most abundant carbon‐storing biopolymers in the biosphere. These phenolic polymers accumulate in different concentrations, compositions, and localisations within and between cell wall layers and cell types. Lignins were acquired during plant terrestrialisation 450 million years ago, and the diversification of their

Foliar spectral signatures reveal adaptive divergence in live oaks (Quercus section Virentes) across species and environmental niches. [PDF]
New PhytolSummary Genomic tools have advanced our understanding of species and population structure, but distinguishing neutral from adaptive evolution remains challenging due to limited methods for measuring a broad spectrum of phenotypic traits. We used spectroscopic data from preserved leaves to test for adaptive divergence among populations of live oaks ...

Lignina em espumas fenólicas [PDF]
Polímeros, 1999 A lignina extraída do bagaço de cana de açúcar pode substituir parcialmente o fenol na preparação de resinas fenólicas. Este trabalho aborda a aplicação de pré-polímero resólico, sendo que o fenol foi parcialmente substituído por lignina (25%, massa lignina/massa fenol ), visando a obtenção de material com características de plástico celular.

Agronomy Journal, Volume 115, Issue 6, Page 3173-3187, November/December 2023., 2023 Abstract When cover crop residues are left on the soil surface, their decomposition is mainly influenced by environmental conditions in residue layers, particularly residue water potential (ψresidue). Thus, models for surface residue decomposition in conservation tillage systems should include a sub‐module that can simulate hourly changes in ψresidue ...
