1. Designing and fabrication of a low-cost dip-coater for rapid production of uniform thin films
In this work, a self-made dip-coater equipment was developed for the fabrication of thin films. The assembly of the apparatus was carried out using simple mechanical and electronic pieces, recycle parts, and spending an inexpensive budget suitably. The production, software design, and features of the device were focused on the sol-gel dip-coating method, whi

3. SALICILATOS COMO INIBIDORES DO PROCESSO OXIDATIVO MEDIADO POR COBRE E FERRO NO BIODIESEL B100
Biodiesel is a renewable fuel produced from vegetable oils and animal fats transesterification. However, due to its chemical characteristics, it is susceptible to oxidation causing losses to its manufacturers and users. In this work a series of salicylates were synthesized and employed as secondary antioxidants in biodiesel B100. The accelerated oxidation te

5. DIFERENCIAÇÃO CATIÔNICA DE BENTONITAS POR INFRAVERMELHO: UM ESTUDO DOS EFEITOS DA HIDRATAÇÃO DOS CÁTIONS TROCÁVEIS
In the bentonite industry, the most common procedure for quality control of the ore and the sodium activation process is the swelling method. However, this tool is restricted only to the differentiation of the sodium and non-sodium types, not considering the other cationic varieties. The objective of this study was to establish parameters for cationic differ

6. Effect of drying on nutritional composition, antioxidant capacity and bioactive compounds of fruits co-products
Abstract Fruit coproducts fruit, made of peels, seeds and pulp, discarded during the industrial processing, contain lots of health beneficial compounds, however, high moisture content limits its use. Drying is a low cost and great potential alternative for using. This study aimed to evaluate the phenolic compounds content, in vitro antioxidant capacity and t

9. Leachate and vinasse used in a biological process combined with Fenton’s reaction: a green method for treatment of textile effluents
Abstract: The production of textiles generates a large amount of liquid residues considered to be environmentally problematic and which, if discarded without due treatment, may cause eutrophication of water sources, the intoxication of living beings, and the blocking of light penetration. Some methods have been applied for the treatment of this type of waste

10. Imidazolium-based Ionic Liquids Impregnated in Silica and Alumina Supports for CO2 Capture
Ionic liquids (ILs) physical immobilization in solid materials is a key strategy for developing efficient and low cost CO2 capture processes. In this work, two porous commercial substrates with different characteristics (silica and alumina) were impregnated with ILs by physical wet method. Imidazolium based IL combined with [Br]- and [Tf2N]- anions were used

11. Production of Carbon Foams from Rice Husk
The production of a material with rigid, multifunctional three-dimensional porous structure at a low cost is still challenging to date. In this work, a light and rigid carbon foam was prepared using rice husk as the basic element through a simple fermentation process followed by carbonization. For the fermentation process, the amount of biological yeast (7.5

12. Effects of adding dried distillers grains with solubles (DDGS) to dog diets supplemented with xylanase and protease
ABSTRACT This study aimed to evaluate the effects of including 200 g kg −1 dried distillers grains with solubles (DDGS) to xylanase- and protease-supplemented diets for dogs on kibble properties, digestibility, fecal characteristics, and palatability. Experimental diets consisted of: 0 g kg −1 DDGS without enzymes (0WE), 0 g kg −1 DDGS with xylanase an
