Composition‐Tunable Lignocellulosic Aerogels From Eucalyptus spp. Bark for Oil and Cu2+ Adsorption

Journal of Applied Polymer Science, EarlyView.
Composition‐tunable lignocellulosic aerogels are produced from Eucalyptus spp. bark by combining cellulose, lignin, and microfibrillated cellulose without post‐synthetic functionalization. The resulting porous architectures show contaminant‐dependent performance: CEL favors cooking‐oil uptake, CEL‐M favors pump‐oil uptake, and CEL‐L‐M provides the ...

Bio‐Based Sodium Alginate Beads Reinforced With Microalgae (Limnospira platensis): Structure–Property Relationships and Controlled Release Potential

Journal of Applied Polymer Science, EarlyView.
Development of sodium alginate beads doped with Limnospira platensis, designed for the gradual release of nutrients and bioactive molecules into soil. The biomaterial combines biodegradability, controlled‐release potential, and microalgal biomass valorization, contributing to reduced nutrient losses through leaching and the development of more ...

Herbarium‐based measurements are reliable predictors of fresh plant traits in Neotropical Myrtaceae

Applications in Plant Sciences, EarlyView.
Abstract Premise Herbarium specimens are increasingly used to extract morphological traits for ecological and evolutionary studies, yet the effects of tissue desiccation on trait measurements remain poorly understood. Here, we tested two hypotheses: (H1) whether higher tissue water content leads to greater measurement changes after herborization and ...
