5. Preparation and Luminescence Properties of Europium(III) Ternary Complex-modified Poplar Wood-based Materials
Inspired by the ultraviolet induced properties of biological materials, we developed fluorescent wood as a new type of functional material which can be applied to anti-counterfeit label technology and wood-emitting artwork. This study discusses the influence of temperature, time, ligand ratio, and reactant concentration on the structure and properties of flu

6. PARTICLE IMAGE VELOCIMETRY FOR ESTIMATING THE YOUNG’S MODULUS OF WOOD SPECIMENS
ABSTRACT Proposing technological innovations in the investigation of the structure and behaviour of wood is important to optimize its use. The assimilation of methods diffused in other areas, such as particle image velocimetry (PIV), can allow a rich range of information for different aspects. The aim of this study was to estimate the Young’s modulus usin

8. Diversidade e estrutura genética de populações de Podocarpus lambertii Klotzsch ex Endl. na floresta ombrófila mista em Santa Catarina
Resumo Podocarpus lambertii (Podocarpaceae) é conhecido popularmente como pinheiro-bravo. Ocorre em várias formações florestais da Mata Atlântica, principalmente na Floresta Ombrófila Mista. Devido à intensa exploração madeireira sofrida pela espécie, ela está presente na categoria “Quase ameaçada” da Lista Vermelha das Espécies Ameaçadas d

9. DISPLACEMENT MEASUREMENT IN SAWN WOOD AND WOOD PANEL BEAMS USING PARTICLE IMAGE VELOCIMETRY
ABSTRACT Throughout their useful life structures demand monitoring to verify their conditions of use. Thus, the need arises to seek methodologies capable to evaluate displacements and deformations in structural components of buildings. The objective of this research was to evaluate the use of the particle image velocimetry (PIV) technique to analyze test spe

11. Genetic Diversity and Structure of Calophyllum brasiliense Along the Santa Catarina Coast
ABSTRACT Population genetics studies can provide knowledge in support of conservation efforts for plant populations. We studied the genetic diversity and structure in nine populations of Calophyllum brasiliense from Santa Catarina state, Brazil, aiming to establish conservation strategies. Allozymic markers were used to genotype about 50 individuals from eac

12. Polyhedral Oligomeric Silsesquioxane (POSS) as Reinforcing Agent for Waterborne Polyurethane Coatings on Wood
Polyhedral oligomeric silsesquioxane (POSS) was added as a reinforcing agent in waterborne polyurethane (WPU)-based coatings to improve their properties. The morphology, structure, thermal stability as well as mechanical properties of the resulting WPU and WPU/POSS hybrid films were investigated. The good compatibility of POSS in the WPU matrices was demonst
