Degradability and biocompatibility of bioglass/poly(amino acid) composites with different surface bioactivity as bone repair materials

Bioglass (BG) possesses excellent bioactivity and has been widely used in the manufacture of biomaterials. In this study, a composite with different surface bioactivity was fabricated via in situ melting polymerization by incorporating BG and poly(amino acid) (PAA) at a suitable ratio. The structure of the composite was characterized by Fourier transform infrared spectroscopy and XRD. The compressive strength of the BG/PAA composites was 139 MPa (BG:PAA = 30:70). The BG/PAA composites were degradable, and higher BG in composite showed higher weight loss after 4 weeks of incubation in simulated body fluid. In addition, the BG/PAA composite maintained adequate residual compressive strength during the degradation period. The SEM results showed the differences in surface bioactivities of the composites directly, and 30BG/PAA composite showed thicker apatite layer and higher Ca/p than 15BG/PAA. in vitro MG-63 cell culture experiments showed that the composite was noncytotoxic and thus allows cells to adhere, proliferate, and differentiate. This indicates that the composite has good biocompatibility. The implantations in the bone defects of rabbits for 4 and 12 weeks were studied. The composites had good biocompatibility and were capable of guiding new bone formation without causing any inflammation. The composite may be successfully used in the development of bone implants.     

Preparation and characterization of TiO2 photoelectrode codoped with aluminum and boron and its application in dye-sensitized solar cell

Nanocrystalline titania films codoped with aluminum and boron were prepared by cathodic vacuum arc deposition. In the process, titanium alloy target was used under an O2/Ar atmosphere, and sensitization of films were carried out by natural dye-sensitized complex in anhydrous ethanol. The structure, surface morphology and UV-vis spectra of titania films codoped were measured by X-ray diffraction analysis, scanning electron microscopy and ultraviolet-visible spectrometer. Theas-deposited films are found to be amorphous. The films annealed were examinedto be of anatase structure with orientation along the (101) planes, the averagecrystal size is in the range between 41 and 45 nm. SEM results show that thereare some pores in the codoped titania films, the optical properties of the dye-sensitized films were also measured which reveals that the spectral responses of films shift to the visible region. Under simulated sunlight illumination, the overall energy conversion efficiency of dye-sensitized nanocrystalline solar cell is 0.9%.     

Einfluß des totvolumens auf die Al2O3-CVD-Abscheidung

The influence of the free gas volume around the substrate on the chemical vapor deposition of Al₂O₃ layers in the AlCl₃/H₂/CO₂ system at different pressures and temperatures has been studied. Through the water gas reaction which occurs homogeneously in the gas phase, the Al₂O₃ growth rate increases with increasing free gas volume until a certain volume is reached, after which it remains constant. For this ‘critical free gas volume’ a theoretical characteristic dimension L_max is introduced. It is defined as the normal distance from a substrate surface, at which the water molecules formed from the CO₂ + H₂ in the gas phase can no longer reach the substrate surface in the time available. The dependencies of L_max on pressure, temperature and gas flow rate deduced through this theoretical consideration show agreement with the experimental results.

Zusammenfassung

Der Einfluß des die Substrate umgebenden Totvolumens auf die Al₂O₃-CVD-Abscheidung im System AlCl₃/H₂/CO₂ wurde systematisch bei verschiedenen Drücken und Temperaturen untersucht. Durch die homogen in der Gasphase ablaufende Wassergasreaktion nimmt in allen Fällen die Abscheidungs-geschwindigkeit mit vergrößerten Totvolumen zuerst zu, bleibt aber ab einer bestimmten Totvolumensgröße konstant. Für diese “kritische Totvolumensgröße” wird die theoretische Kenngröße L_max eingeführt. Diese Größe ist als Normalabstand zur Substratoberfläche definiert, bei dem das in der Gasphase aus CO₂ + H₂ gebildeten Wasser in der zur Verfügung stehenden Zeit die mit AlCl₃ belegte Oberfläche der Substrate nicht mehr erreichen kann. Die aus dieser theoretischen Überlegung abgeleiteten Voraussagen über die Abhängigkeit des L_max von Druck, Temperatur und Gasströmungsgeschwindigkeit zeigten Übereinstimmung mit den Versuchsergebnissen.     

Influence of electroplating conditions on magnetic properties of Fe-36wt.% Ni alloy film

A Fe-Ni soft magnetic film was prepared in sulphate solution by electroplating. The influences of the molar ratio of n [Fe2+ ]/ n [Ni2+ ], current density, bath temperature, pH and L-ascorbic acid concentration on magnetic properties of Fe-Ni alloy film were investigated. The results show that the saturated flux density(BS) of the film increases initially and decreases after it reaches the specific value with the increase of n [Fe2+ ]/ n [Ni2+ ] molar ratio, current density, bath temperature and pH. However, the relationship between L-ascorbic acid concentration and B S keeps linear. It is observed that the coercive force( Hc) is enhanced with the increase of n [Fe2+ ]/ n [Ni2+ ] molar ratio, current density and pH. By comparison, when the bath temperature increases, Hc always decreases. With the increase of L-ascorbic acid concentration, the coercive force increases initially and then decreases.     

Measurement of drill point geometry by using laser sensor

Accurate measurement for the drill geometry is essential to drill design and reconditioning. In recent years, a number of non-contact drill measuring instruments, using CCD camera are reported in the literature. But these systems are not suitable in measuring three-dimensional surface, especially the concave ones. As an effectual remedy, a geometry measurement instrument using laser sensor is developed. This paper describes its configuration and calibration. In addition, the measurement method for a drill flute is detailed. Validity of the system and proposed method are demonstrated by an example. The deviations of the data measured from that inspected by using a microscope are no more than 0.0061 mm.

Some Results for Pythagorean Fuzzy Sets

Pythagorean fuzzy sets (PFSs), originally proposed by Yager (Yager, Abbasov. Int J Intell Syst 2013;28:436–452), are a new tool to deal with vagueness considering the membership grades are pairs satisfying the condition . As a generalized set, PFSs have close relationship with intuitionistic fuzzy sets (IFSs). PFSs can be reduced to IFSs satisfying the condition . However, the related operations of PFSs do not take different conditions into consideration. To better understand PFSs, we propose two operations: division and subtraction, and discuss their properties in detail. Then, based on Pythagorean fuzzy aggregation operators, their properties such as boundedness, idempotency, and monotonicity are investigated. Later, we develop a Pythagorean fuzzy superiority and inferiority ranking method to solve uncertainty multiple attribute group decision making problem. Finally, an illustrative example for evaluating the Internet stocks performance is given to verify the developed approach and to demonstrate its practicality and effectiveness.
