| 1 | In-situ solvothermal processing of polycaprolactone/hydroxyapatite nanocomposites with enhanced mechanical and biological performance for bone tissue engineering显示文摘The interest in biodegradable polymer-matrix nanocomposites with bone regeneration potential has been increasing in recent years.In the present work,a solvothermal process is introduced to prepare hydroxyapatite(HA)nanorod-reinforced polycaprolactone in-situ.A non-aqueous polymer solution containing calcium and phosphorous precursors is prepared and processed in a closed autoclave at different temperatures in the range of 60-150℃.Hydroxyapatite nanorods with varying aspect ratios are formed depending on the processing temperature.X-ray diffraction analysis and field-emission scanning electron microscopy indicate that the HA nanorods are semi-crystalline.Energy-dispersive Xray spectroscopy and Fourier transform infrared spectrometry determine that the ratio of calcium to phosphorous increases as the processing temperature increases.To evaluate the effect of in-situ processing on the mechanical properties of the nanocomposites,highly porous scaffolds(>90%)containing HA nanorods are prepared by employing freeze drying and salt leaching techniques.It is shown that the elastic modulus and strength of the nanocomposites prepared by the in-situ method is superior(~15%)to those of the ex-situ samples(blended HA nanorods with the polymer solution).The enhanced bone regeneration potential of the nanocomposites is shown via an in vitro bioactivity assay in a saturated simulated body fluid.An improved cell viability and proliferation is also shown by employing(3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide)(MTT)assay in human osteosarcoma cell lines.The prepared scaffolds with in vitro regeneration capacity could be potentially useful for orthopaedic applications and maxillofacial surgery. | Saeed Moeini Mohammad Reza Mohammadi Abdolreza Simchi | 2017 | Bioactive Materials2017，2，3： | 8 |
| 2 | Effect of melting temperature on microstructural evolutions, behavior and corrosion morphology of Hadfield austenitic manganese steel in the casting process显示文摘In this study, the effect of melting temperature on the microstructural evolutions, behavior, and corrosion morphology of Hadfield steel in the casting process is investigated. The mold was prepared by the sodium silicate/CO_2 method, using a blind riser, and then the desired molten steel was obtained using a coreless induction furnace. The casting was performed at melting temperatures of 1350, 1400, 1450, and 1500°C, and the cast blocks were immediately quenched in water. Optical microscopy was used to analyze the microstructure, and scanning electron microscopy(SEM) and X-ray diffractrometry(XRD) were used to analyze the corrosion morphology and phase formation in the microstructure, respectively. The corrosion behavior of the samples was analyzed using a potentiodynamic polarization test and electrochemical impedance spectroscopy(EIS) in 3.5 wt% NaCl. The optical microscopy observations and XRD patterns show that the increase in melting temperature led to a decrease of carbides and an increase in the austenite grain size in the Hadfield steel microstructure. The corrosion tests results show that with increasing melting temperature in the casting process, Hadfield steel shows a higher corrosion resistance. The SEM images of the corrosion morphologies show that the reduction of melting temperature in the Hadfield steel casting process induced micro-galvanic corrosion conditions. | Masoud Sabzi Sadegh Moeini Far Saeid Mersagh Dezfuli | 2018 | International Journal of Minerals,Metallurgy and Materials2018，25，12： | 5 |
| 3 | Landslide susceptibility mapping using Genetic Algorithm for the Rule Set Production(GARP) model显示文摘Investigation on landslide phenomenon is necessary for understanding and delineating the landslide prone and safer places for different land use practices. On this basis, a new model known as genetic algorithm for the rule set production was applied in order to assess its efficacy to obtain a better result and a more precise landslide susceptibility map in Klijanerestagh area of Iran. This study considered twelve landslide conditioning factors(LCF) like altitude, slope, aspect, plan curvature, profile curvature, topographic wetness index(TWI), distance from rivers, faults, and roads, land use/cover, and lithology. For modeling purpose, the Genetic Algorithm for the Rule Set Production(GARP) algorithm was applied in order to produce the landslide susceptibility map. Finally, to evaluate the efficacy of the GARP model, receiver operating characteristics curve as well as the Kappa index were employed. Based on these indices, the GARP model predicted the probability of future landslide incidences with the area under the receiver operating characteristics curve(AUC-ROC) values of 0.932, and 0.907 for training and validating datasets, respectively. In addition, Kappa values for the training and validating datasets were computed as 0.775, and 0.716, respectively. Thus, it can be concluded that the GARP algorithm can be a new but effective method for generating landslide susceptibility maps(LSMs). Furthermore, higher contribution of the lithology, distance from roads, and distance from faults was observed, while lower contribution was attributed to soil, profile curvature, and TWI factors. The introduced methodology in this paper can be suggested for other areas with similar topographical and hydrogeological characteristics for land use planning and reducing the landslide damages. | Fatemeh ADINEH Baharak MOTAMEDVAZIRI Hasan AHMADI Abolfazl MOEINI | 2018 | Journal of Mountain Science2018，15，9： | 4 |
