1. Quality Control for Lignin and Gelatin Microcapsules Loaded with Orange Essential Oil
Sustainable natural product-based microstructured systems and biopolymers are strong candidates for use in crop protection. Lignin and gelatin microcapsules loaded with orange essential oil were developed with spray-drying in order to enhance its potential. We evaluated the microparticle controlled release mechanisms, biological effects, structural and therm

2. Polyurethane/poly (Ionic Liquids) Cellulosic Composites and their Evaluation for Separation of CO2 from Natural Gas
The development of both versatile and inexpensive sorbents for CO2/CH4 separation has become one of the greatest challenges to the environment and natural gas processing. This study reports the preparation and characterization of polyurethane (PU)/ cellulose based poly(ionic liquid)(CPIL) composites for CO2/CH4 separation. PU matrix was reinforced with CPIL

3. Thermal Properties of the Blends of Methyl and Ethyl Esters Prepared from Babassu and Soybean Oils
Fatty acid esters (methyl and ethyl) prepared from babassu nut oil were blended with the respective esters from soybean oil. These binary blends (babassu:soybean) were made in proportions of 10:90, 20:80, 30:70, 40:60, and 50:50 (vol%). The ester content of all the blends was higher than 96.5%, which is the minimum value required by the Brazilian National Ag

4. Analysis of combustion efficiency in a pelletizing furnace
Abstract The objective of this research is to assess how much the improvement in the combustion reaction efficiency can reduce fuel consumption, maintaining the same thermal energy rate provided by the reaction in a pelletizing furnace. The furnace for pelletizing iron ore is a complex thermal machine, in terms of energy balance. It contains recirculation fa

5. Study of Pipeline Steels with Acicular Ferrite Microstructure and Ferrite-bainite Dual-phase Microstructure
Three kinds of X70 steels with the same chemical composition and different microstructures fabricated by varying processes were compared in aspect of the microstructures and mechanical properties using SEM, TEM and tensile testing machine. The experimental results showed that the steel 1 with acicular ferritic microstructure fabricated by thermal-mechanical

9. Desafios e oportunidades da geração eólica e termelétrica a gás natural no Sistema Elétrico Peruano. / Challenges and opportunities of the wind generation and to natural gas thermal in the Peruvian Electricity System.
Several countries around the world have increasingly sought to diversify their electrical matrix in order to reduce dependence on fossil fuels and reduce emissions of gases responsible for worsening greenhouse effect in the atmosphere. As a result, has grown the participation of some renewable energy sources that until two decades ago did not occupied a prom

10. A swirler stabilized combustion chamber for a micro-gas turbine fuelled with natural gas
Micro-gas turbines are a good alternative for on-site power generation, since their operation is very reliable. The possibility of operating with various fuels increases versatility and, as a result, the usage of these devices. Focusing on a performance improvement of a tri-fuel low-cost micro-gas turbine, this work presents investigations of the inner flow

11. Employment of acoustic field for pollutant emission reduction under lean combustion
Pulsating combustion is a technique that directly intervenes in combustion processes modifying pollutant emissions and increasing thermal efficiency by varying pressure and temperature in the flame region. The pulsations accelerate mixture rate between oxidant and fuel, resulting in a more intense combustion process, with low fuel waste and potential for low
