Solution-processed dielectric films and Au RF antenna for temperature sensing (open access)

Solution-processed dielectric films and Au RF antenna for temperature sensing

Article discusses how sensing temperature is important for a wide variety of applications such as control systems and instrumentation which are integral to various industrial sectors and in research settings. The authors emphasize the importance of high sensitivity and reliable methods using a frequency-based approach for detecting temperature changes. In their study, Au rectangular single-arm spiral antennas with varying sizes were fabricated and RF S-parameter measurements were conducted over the frequency range of 300 kHz to 20 GHz. Alongside the experimental measurements, they also present results from their simulation analysis conducted using High Frequency Structure Simulator (HFSS) from ANSYS.

Editorial: Superlubricity across the scales

Article talks about how while the idea of frictionless surfaces and the associated implications of vanishing energy losses during mechanical motion have been part of science fiction culture, scientists in the real world work toward realizing this ambitious goal that was once thought to be unattainable. The overarching goal of the research topic titled “Superlubricity Across the Scales” is to provide a snapshot of the latest developments in this rapidly accelerating field of research.

Effect of Polymer Removal on the Morphology and Phase of the Nanoparticles in All-Inorganic Heterostructures Synthesized via Two-Step Polymer Infiltration

This article uses iron oxide/alumina heterostructures formed by two-step infiltration of polystyrene-block-polyvinyl pyridine block copolymer with iron and aluminum precursors from the solution and vapor-phases, respectively, to show that the phase and morphology of iron oxide nanoparticles dramatically depend on the approach used to remove the polymer. The article extends the boundaries of structure manipulations in multicomponent heterostructures synthesized using polymer infiltration synthesis and their properties.

Tribological Properties of (EN AW-AlCu4MgSi(A)) Aluminium Alloy Surface Layer After Ball Burnishing (open access)

Tribological Properties of (EN AW-AlCu4MgSi(A)) Aluminium Alloy Surface Layer After Ball Burnishing

Article presents the tribological properties of (EN AW-AlCu4MgSi(A)) aluminium alloy surface layer after ball burnishing. EN AW-AlCu4MgSi(A) aluminium alloy is widely used as a structural material in aerospace and automotive applications. The authors have subjected it to grinding, polishing and ball burnishing. The authors have performed ball-on-disk tribological tests. We have also determined normalized 3D roughness parameters. High surface smoothness turns out to be obtainable. Favorable effect of the ball burnishing on the tribological properties of the alloy are seen. Results will be presented at the International Scientific Conference BALTTRIB, 2015.
