采用水热沉淀法制备了La0.9M0.1Ga0.8Mg0.2O3-α(M=Ca2+,Sr2+,Ba2+)陶瓷样品的前驱体,沉淀剂来自尿素在水热条件下的水解产物.前驱体经煅烧和烧结后得到陶瓷样品.XRD显示样品具有单一的斜方晶LaGaO3钙钛矿结构.同位素效应和氢的电化学透过(氢泵)实验证明陶瓷样品具有质子导电性.用AC阻抗谱法测定了样品在300～600℃、氢气气氛中的质子电导率,其大小取决于La位掺杂的碱土金属离子:σ(M=Sr2+)>σ(M=Ba2+)>σ(M=Ca2+).以La0.9M0.1Ga0.8Mg0.2O3-α为固体电解质进行了常压合成氨,最佳合成温度为520℃.当施加的电流密度为1mA·cm-2、合成温度为520℃时,氨产率分别为:1.63×10–9mol·s-1·cm-2(M=Ca2+),2.53×10-9mol·s-1·cm-2(M=Sr2+)和2.04×10-9mol·s-1·cm-2(M=Ba2+).

AIM: To determine whether there is a functional difference between patients who actively follow-up in the office(OFU) and those who are non-compliant with office follow-up visits(NFU). METHODS: We reviewed a consecutive group of 588patients, who had undergone total joint arthroplasty(TJA), for compliance and functional outcomes at one to two years post-operatively. All patients were given verbal instructions by the primary surgeon to return at one year for routine follow-up visits. Patients that were compliant with the instructions at one year were placed in the OFU cohort, while those who were non-compliant were placed in the NFU cohort. Survey mailings and telephone interviews were utilized to obtain complete follow-up for the cohort. A χ2 test and an unpaired t test were used for comparison of baseline characteristics. Analysis of covariance was used to compare the mean clinical outcomes after controlling for confounding ***: Complete follow-up data was collected on 554 of the 588 total patients(93%), with 75.5% of patients assigned to the OFU cohort and 24.5% assigned to the NFU cohort. We found significant differences between the cohorts with the OFU group having a higher mean age(P = 0.026) and a greater proportion of females(P = 0.041). No significant differences were found in either the SF12 or WOMAC scores at baseline or at 12 mo ***: Patients who are compliant to routine follow-up visits at one to two years post-operation do not experience better patient reported outcomes than those that are non-compliant. Additionally, after TJA, older women are more likely to be compliant in following surgeon instructions with regard to follow-up office care.

采用水热合成工艺,以钛酸丁酯(Ti(OC4H9)4)为前驱体,通过改变反应物的体积分数和体系的pH值,合成了不同晶型和形貌的二氧化钛(TiO2)微粒.同时,使用X射线衍射仪(XRD)和扫描电子显微镜(SEM)对此产物进行了表征.结果表明:反应物的体积分数和pH值对TiO2微粒的晶型、形貌和晶粒尺寸均有较大的影响.当Ti(OC4H9)4体积分数较大时,出现锐钛矿型晶体,但结晶不完善,微粒较大,且有团聚现象;Ti(OC4H9)4体积分数较小时,出现金红石型晶体,微粒相对较小,随着反应物体积分数的减小微粒的晶型由锐钛矿型转为金红石型,晶粒尺寸逐渐增大.在酸性溶液中,有利于形成金红石型微粒,而在碱性溶液中,有利于形成锐钛矿型微粒,随着体系的pH值增加,晶粒尺寸也逐渐增大.
