| 1 | Sol-gel derived HA/TiO_2 double coatings on Ti scaffolds for orthopaedic applications显示文摘Hydroxyapatite/titania (HA/TiO2) double layers were coated onto Ti scaffolds throughout for orthopaedic applications by sol-gel method. Differential scanning calorimetry (DSC), thermogravimetric analysis (TG) and X-ray diffractometry (XRD) were used for the characterisation of the phase transformations of the dried gels and coated surface structures. Scanning electron microscope (SEM) equipped with energy dispersive spectrometry (EDS) was used for the observation and evaluation of the morphology and phases of the surface layers and for the assessment of the in vitro tests. The in vitro assessments were performed by soaking the HA/TiO2 double coated samples into the simulated body fluid (SBF) for various periods. The TiO2 dipping-coating method at a speed of 12 cm/min, followed by a heat treatment at 600 ℃ for 20 min. The HA la lyaeyre wr wasa ssu cbosaetqeude bnytl ya dipping-coated on the outer surface at the same speed and then heat-treated at difference temperatures. The results indicat that the HA phase begins to crystallize after a heat treatment at 560 ℃. The crystallinity increases obviously at 760 ℃. SEM observations find no delamination or crack at the interfaces of HA/TiO2 and TiO2/Ti. The HA/TiO2 coated Ti scaffolds displays excellent bone-like apatite forming ability when it is soaked into SBF. Ti scaffolds after HA/TiO2 double coatings can be anticipated as promising implant materials for orthopaedic | XU W HU W Y LI M H MA Q Q P. D.

| 4 | Advances in Effects of Sound Waves on Plants显示文摘Sound waves technology has been applied to different plants.It has been found that sound waves were at different frequencies,sound pressure levels(SPLs),exposure periods,and distances from the source of sound infl uence plant growth.Experiments have been conducted in the open field and under greenhouse growing conditions with different levels of audible sound frequencies and sound pressure levels.Sound waves at 1 kHz and 100 dB for 1 h within a distance of 0.20 m could significantly promote the division and cell wall fl uidity of callus cells and also significantly enhance the activity of protective enzymes and endogenous hormones.Sound waves stimulation could increase the plant plasma-membrane H+-ATPase activity,the contents of soluble sugar,soluble protein,and amylase activity of callus.Moreover,sound waves could increase the content of RNA and the level of transcription.Stress-induced genes could switch on under sound stimulation.Sound waves at 0.1-1 kHz and SPL of(70±5)dB for 3 h from plant acoustic frequency technology(PAFT)generator within a distance ranged from 30 to 60 m every other day significantly increased the yield of sweet pepper,cucumber and tomato by 30.05,37.1and 13.2%,respectively.Furthermore,the yield of lettuce,spinach,cotton,rice,and wheat were increased by 19.6,22.7,11.4,5.7,and 17.0%,respectively.Sound waves may also strengthen plant immune systems.It has been proved that spider mite,aphids,gray mold,late blight and virus disease of tomatoes in the greenhouses decreased by 6.0,8.0,9.0,11.0,and 8.0%,respectively,and the sheath blight of rice was reduced by 50%.This paper provides an overview of literature for the effects of sound waves on various growth parameters of plant at different growth stages. | Reda H E Hassanien HOU Tian-zhen LI Yu-feng LI Bao-ming | 2014 | Journal of Integrative Agriculture2014,13,2: | 2 |
