1. Cross-linked coacervates of cashew gum and gelatin in the encapsulation of pequi oil
RESUMO: O óleo de pequi é rico em compostos bioativos, os quais podem ser encapsulados para aumentar a proteção a fatores extrínsecos. A tecnologia de microencapsulamento, além de retardar a degradação do composto ativo, possibilita mascarar aromas e sabores indesejáveis. A coacervação complexa é uma técnica baseada na interação eletrostátic

3. Light Response of Three Water-Soluble MnI PhotoCORMs: Spectroscopic Features and CO Release Investigation
Currently, there is great interest in the study of water-soluble metal compounds capable of releasing carbon monoxide, due to their potential therapeutic use. This paper reports the synthesis, spectroscopic characteristics and CO release properties of three water-soluble manganese(I) carbonyl compounds [Mn(aaz)(CO)3]Br (1; where aaz = 6-amino-6-methylperhydr

4. Identification of a novel plant-derived attractant for Acromyrmex lobicornis leaf-cutting ants
Abstract: Leaf-cutting ants are considered major pests of agriculture and forestry in the Neotropics. Attractive toxic baits are the prevailing method for managing them. Thus, there is great interest in identifying attractants to incorporate into these baits. Moreover, leaf-cutting ants can avoid toxic baits by associating the attractant with the toxin. We e

7. Morphology of the DIN 100Cr6 Case Hardened Steel after Plasma Nitrocarburizing Process
Nitrocarburizing is considered one of the most important thermochemical treatments for surface modification of metallic materials and involves the simultaneous diffusion of nitrogen and carbon onto the surface. Understanding and controlling the formation of the nitrocarburized layer have considerable industrial interest due to the improvements regarding wear

8. Intumescent Coatings Based on Tannins for Fire Protection
Accidents involving fire occur every day around the world, affecting thousands of people and causing economic losses. Some accidents are caused by steel structure failures, which experience a significant reduction in mechanical properties at temperatures of 400-550˚C. Therefore, fire protective coatings are required for steel structures and interest in the

9. Protección antiincrustante de estructuras sumergidas mediante recubrimientos formulados con 7-hidroxi-4-metilcumarina
ABSTRACT Biofouling settlement on submerged structures such as ships, buoys, farms, off-shore platforms and meteorological stations induces economic losses as a consequence of material deterioration and withdraw from service. Environmental regulations focus on the use of environmental friendly products to replace metallic biocides included in antifouling pai

10. Influencia del calcio en la retención de humedad por arcilla
ABSTRACT Bentonite as a raw material is an economical alternative to produce desiccants. The literature indicates that it is a good water adsorbent in relation to the desiccants commonly used in industry (silica gel, molecular sieve). In this sense, it is a valid alternative and an economic option since the clay is a natural compound, which makes it environm

11. The dispersion curve applied in guided wave propagation in prismatic rods.
Abstract The early detection of failures in structures is a subject of great interest in engineering; several of these techniques are linked with the elastic wave propagation, using guided waves is one of these alternatives. Several structures of interest in engineering are laminar arrangements; the wave propagation in this type of structures depends not on

12. Acetylcholinesterase inhibition and antimicrobial activity of hydroxyl amides synthesized from natural products derivatives
ABSTRACT Thirteen natural products derivatives of hydroxyl amide class, three described for the first time, were synthesized by reaction of three indole acids and 3,4,5-trimethoxybenzoic acid with six different amino alcohols in the presence of triphenylphosphine and N-bromosuccinimide. The derivatives were tested against the Gram (+) bacteria Staphylococcus
