1硼酸-硫酸阳极氧化2A97Al-Cu-Li合金在热带海洋大气环境中的初期腐蚀机理显示文摘采用光学显微镜、扫描电镜、能谱仪、电化学阻抗谱测试结合超薄切片,分析阳极氧化2A97Al-Cu-Li合金在大气腐蚀前后的微观形貌、化学成分及电化学性能。结果表明:在不同温度利用含有硼酸-硫酸或酒石酸-硫酸组合的电解液生长膜层时,硼酸添加和较高温度允许较大的电流密度通过,使膜生长加速;对于不同电解液,孔的几何构形和结构相似;硼酸-硫酸阳极氧化试样在热带海洋大气环境中暴露1个月后,出现主要由O,Al,Cl,Cu组成的分散性黑色锈斑,表面产生白色沉淀;随着户外暴露时间的延长,合金发生严重的点蚀并深入合金内部,腐蚀的扩展与θ相粒子有关。骆晨 Sergiu P.Albu 孙志华 汤智慧 陆峰 Xiaorong Zhou 2016材料工程2016,44,9:10
2阿尔泰林蛙的物种有效性及其分类地位——来自系统发育分析的证据(英文)显示文摘为检验阿尔泰林蛙(Rana altaica)的系统发育地位及其物种有效性,该文运用线粒体细胞色素b基因,应用贝叶斯分析和最大简约方法构建了欧亚大陆分布的部分林蛙的系统发育关系。两种分析方法均支持阿尔泰林蛙在田野林蛙(R.arvalis)这一分支的内部。单倍型网络图显示来自阿尔泰地区和中西伯利亚地区所谓的阿尔泰林蛙与田野林蛙有共享单倍型。通过该文母系遗传发育分析结果显示阿尔泰林蛙种级地位不成立,是田野林蛙的同物异名。另外,该文实验分析结果提示,对中国分布的林蛙内部种组划分应建立在系统进化关系的基础上重新进行评估。杨军校 周炜帏 饶定齐 POYARKOV A.Nikolay KUZMIN Sergius L 车静 2010Zoological Research2010,31,4:6

4不同株行距和树形对高密度栽植樱桃产量的影响显示文摘优质樱桃的生产取决于品种、砧木、栽植密度、树形、树势、树龄、果实着生位置、果树负载量、农药和生长调节剂的使用等环境因素和农业技术管理措施。在樱桃的栽培管理中,应选择正确的授粉品种结合适合的砧木、树形和栽培密度。摩尔多瓦共和国的气候条件非常适合樱桃高密度栽培,但现在很多樱桃果园仍然是传统栽培模式。摩尔多瓦共和国政府为建立现代樱桃园的果农提供有吸引力的补贴,鼓励选择适宜的品种、砧木和树形,以实现果园现代化生产。Igor IVANOV Valerian BALAN Ananie PE?TEANU Sergiu VAMA?ESCU Petru BALAN Vasile ?ARBN 赵慧 2019烟台果树2019,0,3:2
5Concept and proof for an all-silicon MEMS micro speaker utilizing air chambers显示文摘MEMS-based micro speakers are attractive candidates as sound transducers for smart devices,particularly wearables and hearables.For such devices,high sound pressure levels,low harmonic distortion and low power consumption are required for industrial,consumer and medical applications.The ability to integrate with microelectronic circuitry,as well as scalable batch production to enable low unit costs,are the key factors benchmarking a technology.The Nanoscopic Electrostatic Drive based,novel micro speaker concept presented in this work essentially comprises inplane,electrostatic bending actuators,and uses the chip volume rather than the its surface for sound generation.We describe the principle,design,fabrication,and first characterization results.Various design options and governing equations are given and discussed.In a standard acoustical test setup(ear simulator),a MEMS micro speaker generated a sound pressure level of 69 dB at 500 Hz with a total harmonic distortion of 4.4%,thus proving the concept.Further potential on sound pressure as well as linearity improvement is outlined.We expect that the described methods can be used to enhance and design other MEMS devices and foster modeling and simulation approaches.Bert Kaiser Sergiu Langa Lutz Ehrig Michael Stolz Hermann Schenk Holger Conrad Harald Schenk Klaus Schimmanz David Schuffenhauer 2019Microsystems & Nanoengineering2019,5,1:2

11纳米纤维素基柔性导电薄膜的构筑及其在柔性电子器件中的应用研究进展显示文摘纳米纤维素(NC)因具有高比表面积、优异的力学性能、出色的热稳定性和可生物降解性,是柔性储能设备电极材料的理想候选者。在柔性电子器件的应用中,通常将NC与导电材料结合以提高其导电性。本文从NC的结构特点出发,综述了NC基导电薄膜的形成及其在柔性电子器件的应用,总结分析了NC基导电薄膜在实际应用中存在的问题和挑战,并对其未来的研究方向进行展望。刘亚丽 张素风 李楠 李磊 朱新月 邓婷婷 刘叶 Sergiu Coseri 2023中国造纸2023,42,5:1
12Toward future adaptive deep brain stimulation for Parkinson's disease:the novel biomarker--narrowband gamma oscillation显示文摘Parkinson's disease(PD) is one of the most common neurodegenerative diseases,affecting individuals especially over 60 years of age.In the next three decades,more than 12 million people will suffer from PD worldwide(Rocca,2018).The characteristic symptoms of PD begin as a movement disorder including bradykinesia,resting tremor,rigidity,and postural instability.Hao Ding Sergiu Groppa Muthuraman Muthuraman 2022Neural Regeneration Research2022,17,3:1
