An SEM in situ uniaxial tensile testing setup allowing HR-EBSD acquisition during deformation was used to study the extension twinning mechanism in magnesium (Mg) at the micron scale. Structures were fabricated with two different crystal orientations, respectively perfectly aligned with, and at 5° to, the [0001] axis. Limited {1012} twin formation was identified in the former case, while twinning was...
Targeted drug delivery is currently emerging as a promising approach to overcome the limits of currently employed administration techniques. The most convenient methodology to control drug delivery is the applica-tion of stimuli-responsive materials, which can release drugs only when required, to remotely controlled microdevices able to navigate human body. Thanks to this synergy, release can be controlled...
Construction of segregated structures within conductive polymer composites (CPCs) is a prospective strategy to enhance electromagnetic interference (EMI) shielding effectiveness (SE). However, the CPCs of segregated struc-tures frequently experience worsened mechanical performances due to weak interface reactions between adja-cent polymer domains, which are hindered by conductive fillers. Herein, 3D-printed...
Two-dimensional nanomaterials are able to sustain ultra-large elastic strains, which in turn hold potential to alter the many functional properties. However, to achieve such large elastic strains in macro-forms suitable for appli-cations has been a challenge. This paper reports an innovative approach to overcome this challenge by using a martensitic transforming substrate to induce ultra-large elastic...
The advantages of modern high temperature sintering processes with controlled atmospheres are well known, but the development of industrial scale sintering equipment has been very limited over the last decade. Parts producers tend to select classical sintering equipment, missing out on the great potentials new system could offer. To demonstrate the strength of high temperature sintering, fast cooling...
Nanotube surface topography modification is becoming a promising topic given the interest in increasing the implant osseointegration rate. In this work, a nanotube oxide layer was obtained on Ti-35Nb-10Ta and Ti6Al4V ELI alloys by an anodic oxidation process, using an electrolyte containing 1 M H3PO4 and 0,8 w.t. % NaF at room temperature. This study focuses on analyzing the electrochemical behavior...
The pure Mo and Ta-doped Mo targets with different microstructures were sputtered by the same sputtering line under the same sputtering process. The structures, surface morphologies and corrosion resisting properties of the films have been analyzed with XRD and SEM, square resistance and corrosion resistance have been measured with four-probe array method and salt spray test. The results indicate...
The production of CrSiW systems is restricted due to the significantly diverging melting points as well as the high oxygen affinity of every individual element. Powder metallurgical productions offer considerable advantages such as an implementation of the process under inert atmosphere to avoid oxidations. This paper will analyze the impacts of two different W particle size modifications (3 and 0...
