In this paper, the common problems of the preparation of hydroxyapatite (HA) bioactive coating on the surface of titanium and titanium alloy were described, which included bonding strength and biological activity. The improvement of the bonding strength between coating and matrix could be reached by using proper prepa…
Low-temperature study of matter provides a key to understanding its fundamental properties. Under conditions where thermal fluctuations do not mask fine interactions, quantum cooperative phenomena that have no analogy in classical physics come into play. Among them are superconductivity, low-temperature exotic magneti…
BACKGROUND: There is scant data on actionable parameters that may improve local control (LC) after SRS for brain metastases. We evaluated the impact of various patient, tumor, and dosimetric variables on LC of NSCLC brain metastases with SRS. METHODS: Patients with NSCLC brain metastases treated with single fraction S…
A planar hybrid microcavity containing isolated diamond particles with embedded silicon-vacancy (Si-V) color centers in its active layer is fabricated by plasma-enhanced chemical vapor deposition. Distributed Bragg reflectors are produced on the basis of alternating quarter-wave a-Si1 − x C x :H and a-SiO2 layers. The…
In order to optimize the well control equipments of nitrogen drilling, the wellhead equipments have been inspected and analyzed systematically, and the failure analysis has been performed for the fracture at the through hole of two valve plates of flat valve at the side outlet of the multi-function four-way valve in t…
A method of one-stage formation of mesoporous structures on the surface of anodically oxidized aluminum with optimized synthesis time was developed. The chemical etching of surface as a method for application of pre-structural pore pattern was introduced into a scheme of preliminary operations for the first time. The…
It is generally believed that materials with high imaginary permeability and high imaginary permittivity are effective absorbers. For specific samples, however, the adjustment of input impedance is still necessary for the sample property optimization. By analyzing the relation between the diffraction rate and the inpu…
By taking Ti-B4C and CrO3-Al as the primary system and the subsystem respectively, the curve dependence of CrO3-Al subsystem on the adiabatic temperature of the reactive system was calculated in chemical dynamics, and laminated composite with TiB2-based ceramic to stainless steel was achieved without Al2O3 inclusions…
The electronic structures of molecule-based nanoparticles, such as biomineralized Helicobacter pylori ferritin (Hpf), Heme, and RbCo[Fe(CN) 6 ]H 2 O (RbCoFe) Prussian blue analogue, have been investigated by employing photoemission spectroscopy and soft X-ray absorption spectroscopy. Fe ions are found to be nearly tri…
CrNx coatings were deposited by high power pulse magnetron sputtering in a closed field unbalanced system. The influence of pulse width on microstructure and mechanical properties of CrNx coatings was examined. Morphologies different from those fabricated by traditional magnetron sputtering were obtained, phase struct…
On page 7043, S.-W. Cho, T. Lee, and co-workers demonstrate human adipose-derived stem cell spheroids exhibiting enhanced viability, cell-cell, and cell-matrix interaction that can be prepared using a nanowire superhydrophobic surface with on-and-off water adhesion switch. The stem cell spheroids produced on this surf…
In this paper using scanning electron microscope, contactless microwave electronic transport and the Raman spectroscopy we studied the properties of graphene deposited on GaN nanowires and compared it with the graphene deposited on GaN epilayer. The Raman micro-mapping showed that nanowires locally change the strain a…
In this paper, we have employed density functional theory (DFT) to investigate the adsorption mechanisms of atomic hydrogens on the sidewalls of (3, 3) single-wall carbon nanotubes (CNTs) which have vacancy defects. All the calculations were performed using the generalized gradient approximation (GGA) with the Perdew,…
Microstructural evolution of AZ61 magnesium alloy was analyzed after ECAE process. This research focused on the effects of deformation temperature and extrusion passes on microstructure of AZ61 magnesium alloy. The results showed that microstructure have not improved significantly at the lower temperature. Grains can…
A quantitative proteomic analysis by C. Chen, T. Wei, and co-workers on page 6922 shows that gold nanorods (AuNRs) effectively inhibit the metastatic phenotype of cancer cells by modulating the expression of energy metabolism-related genes, which might provide a new direction for future investigations of functionalize…
In order to explore size formability in the molding process of biomass buffer composites and improve quality of foam molding of composites, this paper designed tests of molding make-up and conducted macroscopic characterization to cavity flow of the size. Test results showed that the effect sequence of various factors…
Si3N4-SiC-C refractory composites were prepared under the condition of 1100 °C × 1 h with Si3N4and SiC as the raw material and the sucrose and phenolic resin as the binder. The effects of the amount of the sucrose in the binder on the properties of Si3N4-SiC-C refractory composites were studied. The results indicated…
