4. 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. MicrogeraÃÃo de energia elÃtrica com gÃs de sÃntese de um gaseificador concorrente utilizando ItaÃba mazilaurus / Microgeneration of electricity with syngas from a downtraft gasifier using ItaÃba mazilaurus
The use of biomass as energy source is one of the most promising, because it contributes to reduce emissions of carbon dioxide in the atmosphere and allow the decentralized energy generation. Gasification is a technology of processing biomass energy into a gaseous biofuel of low calorific value. The gas can be used in Otto cycle engine for power generation i

7. Mechanized methods for harvesting residual biomass from Mediterranean fruit tree cultivations
This study evaluates the technology and work systems used in order to harvest residual biomass from pruning in the specific conditions of Mediterranean fruit orchards (narrow distances between crop-rows). Harvesting has been divided into several types of operations - pruning, biomass alignment between crop tracks, biomass concentration in piles, chipping and

10. Management of residues of the urban arborization / Gestão de resíduos da arborização urbana
A falta de modelos eficientes para a gestão dos resíduos da arborização urbana tem contribuído para agravar os problemas ambientais, sociais e econômicos resultantes da disposição inadequada desses materiais. Por suas características, esses materiais apresentam potencial para serem aproveitados em pequenos objetos de madeira (POM), composto orgânic

11. Numerical and experimental thermal analysis of a tunnel kiln used in ceramic production
The available technology for tunnel kilns in Brazil is practically empirical and there is a lack of fundamental studies developed as an aid for the design of new kilns or for the retrofit of old ones. Here, a thermal model of a tunnel kiln is developed allowing the numerical simulation of kilns and dryers aiming toward a more efficient and less energy consum
