In order to meet the requirements of sustainable growth and development for human beings, biomedical research has been focus our attention. Terahertz (THz) is recognized as one most promising technologies it widely used in biomedicine. A depiction basic principle THz spectroscopy imaging at beginning this article, some emerging techniques like microfluidic chips scattering-type scanning near-field (S-SNTS) are investigated well indicated that these have potential tackle shortcomings...
Infiltration of liquid aluminum alloy onto SiC particles requires them to be in wet contact at a high temperature, i.e., wetting angle θ <90°. The chemical reaction between these substances also promotes wetting. calculation shows that the interfacial reduces 66°from more than 120°. It is found infiltration process can roughly divided into following four steps: (1) gestation, (2) for high-temperature particles, (3) tiny pores, and (4) solidification form composite materials. time gestation...
This article presents a wireless packaging design for SiC power device, which displays low induction, good thermal management performance, and excellent high-temperature reliability. A novel organic-free nanomaterial fabricated by ultrafast pulsed laser deposition (PLD) is employed as the bonding material both die attach top. With t <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">on</sub> = 20 s ΔT...
In this paper, a low temperature sintering-bonding process through in-situ formation of silver (Ag) nanoparticles using silver–oxide (Ag2O) microparticles was studied. The Ag2O powders were mixed with triethylene glycol (TEG) to form paste, which used bond the Ag-coated copper (Cu) bulks. results revealed that high helpful increase strength, and joints average shear strength can reach 21.9 MPa at 523 K under 2 for 5 min. And mechanism reaction sintering bonding basically made clear by...
Head-in-pillow (HiP) is a BGA defect which happens when solder balls and paste can't contact well during reflow soldering. Package warpage was one of the major reasons for HiP formation. In this paper, package measured simulated. It found that sensitive to thickness inside chips. A FEM method considering viscoelastic property mold compound introduced simulate warpage. The CTE mismatch contributes more than 90% value reflowing at peak temperature. measure threshold, smallest may lead HiP....
Carbon nanofiber (CNF) reinforced elastomer composites with light weight, sustainability of large deformation, chemical stability, corrosion and fatigue resistance, vibration noise reduction capability can have positive impact on a wide range applications. However, this type composite is still under studied research area due to the difficulties in material handling processing. To improve processing control reproducibility for scale engineering applications, cost effective carbon nanofibers...
<title>Abstract</title> Recognizing that reinforced concrete has a shorter lifespan than anticipated and contributes to environmental pollution, timber structures have regained attention for their renewability eco-friendliness. However, the availability of large-scale suitable modern structural engineering is exceedingly limited. Consequently, reciprocal frames (RF), which utilize small-scale components achieve large spans, opened up new architectural possibilities in construction....
Abstract Foam concrete is one of the most valuable porous materials used in civil and industrial buildings. Sepiolite, a fibrous hydrous magnesium silicate, possesses exceptional qualities such as low thermal conductivity, non-polluting nature, eco-friendliness. In this paper, multi-functional sepiolite-based foam has been fabricated using physical foaming technology. The high sepiolite content unique hierarchical structure endow with excellent adsorption insulation properties. exhibits...
