Influência das geometrias da ferramenta e dos fluidos de corte nas tensões residuais no processo hard turning do aço AISI 4340

Mateus Campos Martins2020-01-01LA Referencia (Red Federada de Repositorios Institucionales de Publicaciones Científicas)

Nos processos de fabricação por usinagem as tensões residuais advêm da combinação dos esforços mecânicos do contato ferramenta/peça e o calor gerado no processo. Os parâmetros de corte, bem como a geometria das ferramentas de corte empregadas, os fluidos de corte usados e a dureza do material usinado, influenciam na o…

Synthesis of 2,1,3-Benzoxadiazole derivatives as new fluorophores-combined experimental, optical, electro, and theoretical study.

Tiago Elias Allievi Frizon、André A. Vieira、Fabrícia Moreira da Silva 等 13 位作者2020-01-01LA Referencia (Red Federada de Repositorios Institucionales de Publicaciones Científicas)

Herein, we report the synthesis and characterization of fluorophores containing a 2,1,3-benzoxadiazole unit associated with a π-conjugated system (D-π-A-π-D). These new fluorophores in solution exhibited an absorption maximum at around ∼419 nm (visible region), as expected for electronic transitions of the π-π ∗ type…

Estudamos o espectro dos níveis de Landau de monocamadas de grafeno além da dispersão linear sem massa de Dirac. Utilizamos um modelo efetivo tight-binding, do tipo Wannier, obtido a partir de cálculos ab initio, que inclui termos integrais de hopping eletrônico de longo alcance. Empregamos o método desenvolvido por H…

Importância da corrosão subpelicular por descontinuidade da película de pintura em estruturas de aço.

Guido Lessa Ribeiro Filho、Rovadávia Aline de Jesus Ribas、Geraldo Donizetti de Paula Paula2020-01-01LA Referencia (Red Federada de Repositorios Institucionales de Publicaciones Científicas)

The impact of varying the dry paint film thickness (DFT) on the underpaint corrosion of steel plates obtained from the floor of an offshore oil platform is evaluated. The specimens were all prepared using the same material and paint scheme, and the DFT and exposure conditions in a salt spray chamber were varied and co…

Nano-pesticides: A great challenge for biodiversity? The need for a broader perspective

Evgenios Agathokleous、Zhaozhong FENG、Ivo Iavicoli 等 4 位作者2020-01-01Zenodo (CERN European Organization for Nuclear Research)

(Uploaded by Plazi for the IPBES Invasive Alien Species Assessment) The need to protect plants against environmental challenges, abiotic and biotic, leads to the application of nanomaterials and pesticides in the environment. Recently, nanopesticides have been developed to replace classic pesticides. Their wide applic…

Introductory Survey

Vijay K. Stokes2020-01-01OpenAlex

Plastics are a relatively new class of materials invented during the past century, mostly over the past 75 years. Here are examples of some common plastics still in use together with the years they were invented: Bakelite (phenolic), 1909; PVC (polyvinyl chloride), 1933; nylon, 1934; Plexiglas® (polymethyl methacrylat…

Thermoset Materials

Vijay K. Stokes2020-01-01OpenAlex

The bulk of the material discussed thus far in this book has been concerned with the structure and properties of, and component design and fabrication with, thermoplastics – materials that soften and melt on heating and can be reshaped by heating and cooling operations. In contrast, in thermosets the coiled, entangled…

Stiffening Mechanisms

Vijay K. Stokes2020-01-01OpenAlex

While plastics have many desirable properties, such as the ease with which they can be used to make complex parts, their relatively low stiffness and strength can limit their structural applications. However, this limitation can be overcome by forming composites in which the plastic matrix acts as a glue that holds st…

O estado atual das rodovias pavimentadas brasileiras revela que menos de um terço das rodovias federais públicas estão em perfeita condição. Dentre os fatores que colaboram para esse prognóstico, estão o método de dimensionamento adotado; as tecnologias e o processo construtivo; a manutenção e o gerenciamento das estr…
