Direct Consolidation of Copper–Graphene Composite by Rotary Swaging
Advanced Engineering Materials, EarlyView.The applicability of the rotary swaging method for preparation of electroconductive copper–graphene composite by direct consolidation of powders is proven. The consolidated material features advantageous microstructure featuring fine grains and twins, with homogeneous distribution of graphene, primarily along the twin boundaries, which contribute to ...

A digital twin for parallel liquid-state nuclear magnetic resonance spectroscopy
Communications EngineeringOne approach to increasing nuclear magnetic resonance measurement sample throughput is to implement multiple, independent detection sites. However, the presence of radio frequency interference poses a challenge in multi-detector systems, particularly in ...

Interface Microstructures in Concrete [PDF]
Materiales de Construcción, 1991 This paper constitutes a compilation as well as an interpretation of the present state of knowledge about the different microstructures developed in the interface areas of concrete, that is, the cement paste-aggregates, the cement paste-reinforcement, the cement paste-fiber, etc.

Advanced Engineering Materials, EarlyView.In this research, ZrC coatings are evaluated against various counterprobes at the microscale using novel super‐stiff atomic force microscopy cantilevers. The chemical composition of the coating is shown to be an important factor influencing coating hardness and Young's modulus, while surface roughness, counterprobe hardness, and surface energy are the ...

Deformable Media with Microstructure [PDF]
, 1993 In this paper we present a formalism which describes in a global fashion deformations of continua with microstructures. In doing so we have to be aware of the fundamental difference between a local and a global approach.

Advanced Engineering Materials, EarlyView.Ni‐base superalloys produced using additive manufacturing (AM) have a different response to heat treatments when compared to their conventional counterparts. Due to such unpredictability, various alloys with industrial interest are currently overlooked in most prior AM research.

Graphene–Catechol Dental Sealant: Antibacterial and Mechanical Evaluation
Advanced Engineering Materials, EarlyView.This study presents dental sealants made with graphene and L‐DOPA‐modified graphene. L‐DOPA enhances graphene dispersion, improving sealant properties. The material shows antibacterial activity against S. mutans and L. casei, along with high strength and elasticity.

Ultra-large elongation and dislocation behavior of nano-sized tantalum single crystals
AIP Advances, 2017 Although extensive simulations and experimental investigations have been carried out, the plastic deformation mechanism of body-centered-cubic (BCC) metals is still unclear. With our home-made device, the in situ tensile tests of single crystal tantalum (
