We developed an ultra-high speed photonic sintering method involving flash white light (FWL) combined with near infrared (NIR) and deep UV light irradiation to produce highly conductive copper nano-ink film. Flash white light irradiation energy and the power of NIR/deep UV were optimized to obtain high conductivity Cu films. Several microscopic and spectroscopic characterization techniques such...

Nano-coated particles and whiskers were used as reinforcing additives for ceramic tool materials to take advantage of synergistic toughening enhancement mechanisms. An Al2O3/TiC/CaF2@SiO2/SiCw material was fabricated by hot-pressing. Self-lubricating toughened nano CaF2@SiO2 coated SiC studied. When the addition content 10 vol% 20 vol%, with best comprehensive properties obtained. The results s...

ceramic dental materials have been considered as alternatives to metals for dental implants application. in this respect, zirconia tetragonal stabilized with %3 yttrium, is of great importance among the ceramic materials for endosseous dental implant application. because of its good mechanical properties and color similar to tooth. the aim and novelty of this study was to design and prepare y-t...

Zirconium diboride ceramics with and without carbon boron carbide nanopowder additives were prepared by ball milling ZrB2 grinding media pressureless sintering. Additions of up to 1 wt% nano-B4C 0.5 C made the powder. The materials then sintered between 1800 2300 °C for 90 360 min in an Ar/10H2 atmosphere. After sintering at 2200 min, densities ranged from 88.3 90.7% 0–1.0% addition. Carbon add...

Alumina nanopowders produced by electrical explosion of wires were sintered using the spark plasma sintering technique. The results of XRD analysis show that the main phase in the compacted nanopowders is α-Al2O3. According to the SEM observations, the sintered alumina nanopowder consists of micron-sized faceted grains and nano-sized necked grains. The increase in sintering temperature resulted...

In this study, a chemical oxidation method was employed to fabricate coral-like Cu2O nano/microstructures on Cu foils as counter electrodes (CEs) for dye-sensitized solar cells (DSSCs). The Cu2O nano/microstructures were prepared at various sintering temperatures (400, 500, 600 and 700 °C) to investigate the influences of the sintering temperature on the DSSC characteristics. First, the Cu foil...

Paper-based writing electronics has received a lot of interest recently due to its potential applications in flexible electronics. To obtain ultra-low resistivity paper-based writing electronics, we developed a kind of ink with high concentration of Ag Nano-particles (up to 80 wt%), as well as a related dispensing writing system consisting an air compressor machine and a dispenser. Additionally...

In this paper we overview and describe the characteristics of various types of RF plasma system, which are used for different applications such as: powder processing; plasma sintering; plasma sterilization; waste treatment; element separation and nano-powder synthesis.

Transparent polycrystalline ceramics exhibit improved mechanical and optical properties. However, synthesizing transparent without additives is nontrivial. Herein, we report the synthesis of two (β-Si3N4 γ-Si3N4) under high pressure temperature from a pure Si3N4 precursor with nano-/micro-dual grain sizes. Synthesized β-Si3N4 exhibited significantly enhanced Vickers hardness reaching 24.2 GPa (...
