Extração de nanocristais de celulose da fibra da vagem de amendoim (Arachis hypogaea)
Diante dos problemas ambientais em relacao reciclagem do plastico e o esgotamento dos recursos fosseis surgiu o interesse em materiais sustentaveis, como a utilizacao de fibras naturais na fabricacao de compositos para substituicao de fibra de vidro e plastico. Uma fonte de fibras naturais e a vagem do amendoim, sendo…
New bridged thienylenphenylene-based D-π-A dyes for efficient Dye-Sensitized Solar Cell: Theoretical study
In this paper, we have designed several novel organic donor-π-acceptor dyes. The electron acceptor group is the 2–cyanoacetic for all dyes; whereas the electron donor is the bridged thienylen-phenylene with varied unit based on a series of X moieties and their influence was analyzed. These dyes were studied by using d…
Supramolecular Organogels Based on N-Benzyl, N’-Acylbispidinols
The acylation of unsymmetrical N-benzylbispidinols in aromatic solvents without external base led to formation of supramolecular gels, which possess different thickness and stability depending on the substituents in para-positions of benzylic group and nature of acylating agent as well as on the nature of the solvent…

Process-induced microstructure in industrial SMC compression : quantitative descriptive analysis and predictability of a state-of-the-art numerical model
Le moulage par compression du SMC est une technologie de mise en oeuvre des polymeres reactifs renforces de fibres coupees pour fabriquer une piece en materiau composite. Le materiau SMC depose et chauffe dans un moule metallique monte sous presse est mis en mouvement par la compression qu’il subit. Le materiau s’ecou…

Study of Wave Propagation in Damaged Composite Material Laminates
The characteristics of carbon fiber composites have enabled these materials to be accepted as replacements for metal parts in industry. However, due to their unsymmetrical material properties, carbon fiber composites are susceptible to damage, such as a delamination, which can cause premature failure in the structure.…
Preparação e caracterização de um novo co-amorfo de tolbutamida com trometamina
A tolbutamida (TBM) e um antidiabetico oral usado no tratamento da Diabetes Mellitus Tipo 2 (DMII). Embora este farmaco possua alta permeabilidade membranar, a sua solubilidade em agua e muito baixa, podendo reduzir a sua biodisponibilidade e eficacia terapeutica. A sintese de co-amorfos de farmacos tornou-se uma alte…
Li-rich Li3MO4 model compounds for deciphering capacity and voltage aspects in anionic redox materials
Global warming, due to the increasing CO2 concentration in the atmosphere, is a major issue of the 21th century, hence the need to move towards the use of renewable energies and the development of electrical storage devices, such as Li-ion batteries. Along that line, a new electrode material called Li-rich NMCs have b…

Surface Degradation of Oxides, Ceramics, Glasses and Polymers
Surface degradation of materials used in engineering, caused by either chemical or physical action, constitutes one of the major costs to industry in pretreatment and maintenance. This chapter describes the recent advances in the understanding of surface degradation mechanisms relating to oxides, oxide films on metal…
Refractory Metal and Alloy Coatings Deposited by Magnetron Sputtering
Refractory metal and alloy coatings have applications at elevated temperatures where improvements in wear corrosion, oxidation, or erosion resistance are required. Chromium can be electrodeposited from aqueous electrolyes; however, to electrodeposit other refractory metals, molten salt electrolytes are normally requir…
The Effectiveness of Non-Destructive Techniques for Assessment of Quality of Plasma-Sprayed Coatings
This chapter gives an overview of some of the more promising contemporary research into nondestructive testing methods, which may have potential for the assessment of the “quality” and thickness of plasma-sprayed coatings. Through the incorporation of sophisticated electronic and microprocessor control technologies, p…
Observations on the Role and Selection of Coatings and Surface Treatments in Manufacturing
The Department of Metallurgy at the University of South Australia is presently following a similar procedure to identify possible viable alternatives to traditional wear-, and corrosion-resistant coatings and surface treatments used in the automobile industry. Under heavy abrasive conditions, thicker coatings produced…
The Present and Future for Coil-Coated Products in the Building Industry
Organic coil-coated steel products have enjoyed rapid growth rates, and this trend is continuing. The available organic coatings range from paint systems formulated to provide coloured, durable surfaces to a number of laminated films that provide the additional properties of texture and toughness. Coil coating is an e…
Validation of Bioburden Recovery
General knowledge of the bioburden is necessary for validating the sterilization process. Bioburden is usually determined after the final manufacturing phase, but raw materials, components, in-process subassemblies and packaging can also be evaluated. Bioburden validation assesses the efficiency and reproducibility of…
