采用金属注射成型(MIM)工艺制备Ti-22Nb(质量分数,%)和商业纯钛(CP-Ti)参比样,并选取电弧熔炼后抛光的Ti-22Nb作为另一种参比样。采用激光共聚焦显微镜、扫描电子显微镜和酶联免疫检测仪检测每组样品的表面拓扑结构和细胞相容性。结果显示,MIM工艺可以得到微米级粗糙度,而且采用混合元素粉而不是单一钛粉作为原料可以获得更高的表面粗糙度和比表面积。所有测试样品都不存在细胞毒性。人原代细胞在MIM Ti-22Nb样品表面(特别是在闭孔附近)的吸附效果更好。

研究了涡轮增压器设计对发动机性能和废气排放的影响。试验用发动机是一台直喷式、中冷、涡轮增压非道路机械用柴油机。本文特别关注发动机的颗粒(PM)排放。先在发动机上装一台标准的非控制涡轮增压器(TC),然后用一台带废气旁通阀的涡轮增压器(WG)替代它。该发动机燃用商品柴油。在整个负荷范围内,该发动机在3种转速下运转并记录了它的主要性能、废气排放以及排气中的颗粒数量。结果表明,带废气旁通阀的涡轮增压发动机在中速、低速高负荷运转时具有低颗粒排放和低烟度的优点,而在额定转速时标准涡轮增压略好于带废气旁通阀的涡轮增压。在废气排放方面,两种试验涡轮增压器之间并无明显差异。如所希望的那样,带废气旁通阀涡轮增压发动机的低速有效扭矩增大。采用废气旁通阀涡轮增压时,最低转速的有效热效率有所改善,几乎与中速时相等,而额定转速时略有下降。将来必须采取有效措施来显著降低试验发动机的毫微颗粒排放,因为这两种涡轮增压的毫微颗粒排放均处于高水平。此外,需要进行颗粒试样的化学分析,以提供每种颗粒的组分信息。以后还需要对整个喷油系统的进一步优化进行研究。

In this study, it was to investigate the swelling performance of novel biohybrid composite hydrogel sorbents containing acrylamide/potassium 3-sulfopropyl methacrylate/sodium alginate/bentonite in water and binary mixtures of water-solvent. Novel hydrogels were synthesized with free radical solution polymerization by using ammonium persulfate/N,N,N’,N’-tetramethylethylenediamine as redox initiating pair in presence of poly(ethylene glycol) diacrylate as crosslinker. Swelling experiments were performed in water and binary mixtures of water-solvent (acetone, methanol and tetrahydrofuran) at 25°C, gravimetrically. Some swelling and diffusion properties of the hydrogels were calculated and they were discussed for the biohybrid/hybrid hydrogel systems prepared under various formulations. It has been seen the lower equilibrium percentage swelling ratio values (62% - 124%) in all solvent compositions in comparison with the equilibrium percentage swelling ratio values in water (718% - 2055%). Consequently, the hydrogel systems developed in this study could serve as a potential device for water and water-solvent binary mixtures.

Dear Editor,Pancreatic ductal adenocarcinoma(PDAC)remains a significant health problem with an increase in the incidence and a five-year survival rate of only 10%[1].The Phosphoinositide 3-kinase-protein kinase-B-mechanistic target of rapamycin(PI3K-AKT-mTOR)pathway is a driver pathway in PDAC and an important therapeutic target[2].We[3]and others[4–6]have demonstrated that the mTOR kinase is a therapeutic target in PDAC,and rationally designed mTOR inhibitor(mTORi)-based combination therapies are emerging[2].
