“…Figure a shows a surface scanning electron microscopy (SEM) image of the sample, where the presence of nanowires (NWs) can be clearly observed. The formation of such NWs is understood to be the result of the Zn‐catalyzed reaction of plasma‐phase Si and O reactants, similar to many reported examples of the metal‐catalyzed formation of NWs that have been reported in the literature …”

Herein, the fabrication of a white luminescent material with photoluminescence (PL) in the region ranging from 350 to 900 nm is reported. Formation of the luminescent material is achieved simply by the high‐temperature (1100 °C) annealing of silicon‐rich oxide nanowires containing a ZnO phase, which are grown by exposing a Zn film to Si and O plasma generated using a mixture of N2O and SiH4 gases at a low temperature (380 °C). The PL spectral response is easily tuned by varying the mixing ratio of the two gases or the Zn film thickness. The generation of white luminescence can be attributed to the hybridization of Si nanocrystals (red), silicon oxide (green), and ZnO (blue)‐based materials.

“…A complementary XPS analysis is used to confirm for the chemical structural information. The survey spectra obtained from both particles prepared reveal the type of chemical bonds formed with the Si element 57 – 59 . In the deconvoluted high-resolution Si (2p) spectrum of the polymeric core particles, two strong peaks corresponding to Si-C (chemical bond of TPM) and Si-O-C (the silicon ethoxide group in the TPM) are observed (Fig.…”

The synthesis of organic-inorganic hybrid particles with highly controlled particle sizes in the micrometer range is a major challenge in many areas of research. Conventional methods are limited for nanometer-scale fabrication because of the difficulty in controlling the size. In this study, we present a microfluidic method for the preparation of organic-inorganic hybrid microparticles with poly (1,10-decanediol dimethacrylate-co-trimethoxysillyl propyl methacrylate) (P (DDMA-co-TPM)) as the core and silica nanoparticles as the shell. In this approach, the droplet-based microfluidic method combined with in situ photopolymerization produces highly monodisperse organic microparticles of P (DDMA-co-TPM) in a simple manner, and the silica nanoparticles gradually grow on the surface of the microparticles prepared via hydrolysis and condensation of tetraethoxysilane (TEOS) in a basic ammonium hydroxide medium without additional surface treatment. This approach leads to a reduction in the number of processes and allows drastically improved size uniformity compared to conventional methods. The morphology, composition, and structure of the hybrid microparticles are analyzed by SEM, TEM, FT-IR, EDS, and XPS, respectively. The results indicate the inorganic shell of the hybrid particles consists of SiO2 nanoparticles of approximately 60 nm. Finally, we experimentally describe the formation mechanism of a silica-coating layer on the organic surface of polymeric core particles.

Barium aluminosilicate (BAS, BaO-Al 2 O 3 -2SiO 2 ) glassceramic material shows excellent thermal stability, high oxidation resistance, high melting point (1760°C), and low dielectric constant. These features have resulted in the widespread use of BAS composites in the area of integrated circuit substrate, electronic package, LCD monitor, refractory composites, and so on. [1][2][3][4][5][6][7][8][9][10][11][12] Whereas the intrinsic low toughness problem has restricted the wider range of applications. Carbon fiber, [13][14][15][16] SiC fiber, [17][18][19] and CNTs [20][21][22][23] are commonly introduced in the glass-ceramic matrix to improve mechanical properties. However, these materials were found to show different drawbacks in the relative researches, such as the poor oxidation resistance of carbon fiber 24 ; the high price of SiC fiber; and the complex synthesis steps of CNTs. 25 Sialon, as a solid solution of Si 3 N 4 , consists of α-Sialon, β-Sialon, O-Sialon, and X-Sialon phases. Among them, β-Sialon is known for the high fracture toughness and excellent thermal stability, making it superior over other reinforcement materials when dealing with high temperature. 4 So the combination of Sialon and BAS not only solves the fatal brittleness problem of BAS, but also improves the thermal performance of BAS matrix.It has been demonstrated that one-dimensional materials, such as nanowires, whiskers, and fibers, exhibit unique structures and properties, which are exploited to build up nano-scale reinforcements.
