Interações de van der Waals na superlubricidade de filmes nanoestruturados e hidrogenado
(2019-03-26)
Friction is originated by energy dissipation events owing to the lost work of non-conservative forces. The nanotribological mechanisms through which this dissipation can occur include molecular deformation and thermal, ...
Desgaste microabrasivo de revestimento níquel-fósforo tratado termicamente aplicado sobre liga Cu-Be C17200
(2022-06-23)
Copper-beryllium alloys are widely used to manufacture thermoplastics injection molds due to their high thermal conductivity. Even though these alloys admit precipitation hardening at temperatures between 250 and 400 ºC, ...
Efeitos da adição de B, Y2O3 e/ou WS2 na microestrutura e no comportamento tribológico do aço inoxidável austenítico produzido por SPS
(2021-08-31)
Austenitic stainless steels are alternatives to meet the demand for advanced materials for applications that aim to reduce energy consumption and deterioration of components due to tribological phenomena such as friction ...
Interações físico-químicas em nanotribologia: elucidação de mecanismos e controle do atrito em escala nanométrica
(2023-08-04)
The study of friction, wear, lubrication, and adhesion at the nanoscale forms nanotribology, an interdisciplinary area dedicated to understanding and promoting advances in the most diverse applications in which these ...
Compósitos baseados em PLA e ABS para impressão 3D de simuladores antropomórficos
(2023-09-15)
Additive manufacturing has been standing out for some years in both scientific and industrial fields. One of the 3D printing methods by material extrusion that stands out is the fused filament fabrication technique (FFF). ...
Pressure-induced second-order phase transition in fluorine
(2023-09-20)
The relative stability between the crystal structure of (alfa)-F2, space group C2/c, and a hypothesized highpressure phase, space group Cmce, was explored using Density Functional Theory at the PBE0+D3(ABC)/TZVP level of ...
Desenvolvimento de uma membrana verde à base de poli(vinil álcool) para a remoção de diclofenaco de sódio de matrizes aquosas
(2023-10-18)
Membrane separation processes are efficient to reduce water pollution by emerging contaminants, such as pharmaceuticals. In Brazil, as well as worldwide, the production of membranes still faces challenges concerning the ...
Efeito de extensores de cadeia e poliol de fonte renovável na estrutura e propriedades de poliuretanos termoplásticos obtidos por processamento reativo
(2024-01-25)
Thermoplastic polyurethanes (TPUs) are highly versatile polymers known for their wide range of properties, achieved through the strategic combination of raw materials, including isocyanates, polyols, and chain extenders. ...
Desenvolvimento e processamento de látex de borracha natural com propriedades antibacterianas para produção de luvas cosméticas para próteses de membros superiores
(2024-04-19)
Upper limb amputations occur frequently throughout the world and are mainly caused by trauma, such as car accidents or accidents involving industrial machinery. The development of prosthetic technologies is a growing need ...
