This paper describes research focused on investigating the effect of hydrogen (H) atom insertion into grain boundaries polycrystalline diamond (PCD) films. is required in order to understand key morphological, chemical, physical, and electronic properties The PCD films were grown using hot filament chemical vapor deposition (HFCVD) process, with flowing Ar gas mixed CH4 H2 gases control film growth microcrystalline (MCD, 0.5–3 µm sizes), nanocrystalline (NCD, 10–500 nm ultrananocrystalline...
3-D additive printing technology has been employed recently for the manufacturing of a wide variety tunable radio frequency (RF) components. In particular, this article is focused on extraction magnetically tuned printed materials suitable RF circuits. The design and modeling circuits require an accurate electromagnetic (EM) characterization dielectric [polylactide (PLA)] as primary substrate, magnetic particles (CoFeO) component in composite copper traces at frequencies. complex...
Diamond polycrystalline films have shown a unique combination of properties such as high wear resistance, hardness, the lowest friction coefficient compared to metal and ceramic coatings, chemical inertness, excellent thermal conductivity, tunable electronic properties, biocompatible properties.Moreover, Ultrananocrystalline diamond (UNCD) exhibit electrical conductivity with either nitrogen incorporated in grain boundaries or boron doping via substitution B for C atoms lattice [1]; enable...
This article describes key material science/technology issues to implement polycrystalline diamond scaffolds enable processes for biological cells growth relevant using grown in the laboratory treatment of human conditions. Issues investigated include 1. Synthesis/characterization microcrystalline (MCD), nanocrystalline (NCD) and transformational ultrananocrystalline (UNCD) coating-based scaffolds. Diamond films were on silicon substrates hot filament chemical vapor deposition (HFCVD)...
<title>Abstract</title> This work presents the effect of interpillar distance in a two-step DRIE process for microneedles fabrication. The consists pillar creation followed by etching till turning it into needle. was carried out dumbell-well pattern. employed pattern adjusted to produce 650 µm microneedle height. density fixed at 657 / cm<sup>2</sup>, and increased reducing area. At short distance, 25 µm, rate is higher on surface; wider 75–100 produces triangular needles. an 200 or greater,...
Gravimeters fabricated with MEMS suffer from temperature-dependent drifts in their long-term stability. We analyze the thermal contributions to signal, and we propose three mechanisms mitigate effects. The first one uses materials that fulfill condition $\alpha_E=-2 \alpha$, where expansion is canceled by temperature variation of Young's modulus. second introduce a compression compensates force spring. In third one, displacement proof mass sensor, rather than force. are robust since they...
