1. Avaliação do efeito do tratamento a plasma sobre a superfície de filmes de polietileno verde e argila vermiculita
RESUMO O Polietileno (PE) Verde é um polímero sintético que apresenta baixa energia superficial, que resulta em fraca propriedade de adesão. Esta baixa adesão, provoca alguns problemas relativos às aplicações práticas dos polímeros, como fraca aderência de tintas de impressão, revestimentos, adesivos e metais à superfície do polímero, entre ou

2. Effect of Galardin and its Solvents on the Microtensile Bond Strength of Different Adhesive Systems to Dentin
Abstract Objective: To evaluate the effect of a synthetic inhibitor of MMPs (Galardin) and its solvents [ethanol and dimethyl sulfoxide (DMSO)] on the microtensile bond strength (µTBS) of adhesive systems to dentin. Material and Methods: Sound human third molars (n=180) were randomly assigned into 5 based on solution type: DMSO; ethanol; Galardin + DMSO;

3. Propriedades de adesivo aplicado em painéis a partir da substituição por lignossulfonato do processo sulfito
Resumo Considerando a indústria de painéis aglomerados, a maior parte utiliza adesivos sintéticos, especialmente, à base de ureia-formaldeído, e nesse sentido, estudos que englobam as características de materiais alternativas para a indústria de painéis tornam-se importantes, especialmente quando se considera o custo final dos produtos gerados. O pre

5. Comportamento das forças de adesão do adesivo selante de silicone e do mastic butílico sob o efeito da radiação ionizante. / Behavior of the adhesion forces of silicone adhesive sealant and butyl mastic after the exposure to ionizing radiation.
Adhesives are products that can keep materials together by bonds between the surfaces. Sealants are products that can keep filled a space between two surfaces, through a barrier that is configured as a \"bridge\" between the two surfaces. The mastic is a product made of a mixture of substances with the primary butyl polymer, with the consistency of a mass no

6. Biomaterial based novel polyurethane adhesives for wood to wood and metal to metal bonding
Polyurethane adhesives made from synthetic chemicals are non-biodegradable, costly and difficult to find raw materials from local market. To avoid solid pollution problem, cost effectiveness and easy availability of raw materials, biomaterials based polyurethane adhesives are used in current industrial interest. Direct use of castor oil in polyurethane adhes

7. Ethyl-2-cyanoacrylate as a sealant of the cecal stump of Rattus norvegicus albinus submitted to parcial resection / O etil-2-cianoacrilato como selante em coto cecal de Rattus norvegicus albinus submetidos a ressecção parcial
Among the devices studied as alternative processes to the means commonly used in the coaptation of surgical wounds, the use of synthetic adhesives has been described and used since the 1950s. They include several cyanoacrylate-based formulations (such as ethyl-2-cyanoacrylate), since they have positive characteristics, such as a being easy to apply, quick po

8. Adesivo de borracha termoplastica reforçado com nanoargila / Thermoplastic rubber adhesive reinforced with nanoclays
Adhesives prepared with thermoplastic rubber are very important for the pressure sensitive adhesives industry due to its easy processability. However, these adhesives are usually not indicated for applications in which temperature resistance around 90o C is required. In this study, thermoplastic rubber adhesives with nanoclays were prepared, in order to eval

9. Obtenção e uso de gradientes de densidade
Osmocentrifugation and contrifugal ultrafiltration were applied to the obtention of solfgeneratod gradients of macromolecular solute. Centrifugal ultrafiltration provides greater gradents in shorter times than in longer times. The range and shape of the density gradients can be varied, by using different centrifugation times and rotor speeds. Fractionation a

10. Glycosylated Hydroxytryptophan in a Mussel Adhesive Protein from Perna viridis*
The 3,4-dihydroxyphenyl-l-alanine (Dopa)-containing proteins of mussel byssus play a critical role in wet adhesion and have inspired versatile new synthetic strategies for adhesives and coatings. Apparently, however, not all mussel adhesive proteins are beholden to Dopa chemistry. The cDNA-deduced sequence of Pvfp-1, a highly aromatic and redox active byssal

11. Biodegradation of halogenated organic compounds.
In this review we discuss the degradation of chlorinated hydrocarbons by microorganisms, emphasizing the physiological, biochemical, and genetic basis of the biodegradation of aliphatic, aromatic, and polycyclic compounds. Many environmentally important xenobiotics are halogenated, especially chlorinated. These compounds are manufactured and used as pesticid
