1适用于柔性高压直流输电网的直流电压下垂控制策略显示文摘基于带死区的直流电压下垂控制,提出一种适用于柔性直流输电网的新型直流电压下垂控制策略,可保障直流与交流系统交换功率的平衡。提出的新型直流电压下垂控制方法首先将各换流站分为4组,之后通过对各换流站组设定不同的电压裕度和死区来设定参与协调控制的不同优先等级,最后提出改进的'功率—电压'特性曲线来确保各换流站在暂态下具备良好的动态特性。仿真测试系统的交流部分为IEEE 39节点系统,直流部分为一个5端直流电网系统,其中换流器类型为401电平模块化多电平换流器。通过对该交直流混合系统的测试,文中提出的新型直流电压下垂控制方法可以在故障发生后有效地使系统过渡至新的稳态运行点。在暂态过程中,各换流站具备良好的动态特性。李海峰 刘崇茹 李庚银 Iravani REZA 2016电力系统自动化2016,40,21:10
2活性炭负载硫化锡纳米颗粒作为高效可重复使用Lewis酸催化剂催化三组分一锅法合成4H-吡喃[2,3-c]吡唑衍生物(英文)显示文摘Tin sulfide nanoparticles(SnS -NPs) were prepared in aqueous solution at room temperature on the surface of activated carbon(AC) and were investigated using field-emission scanning electron mi-croscopy(FE-SEM), transmission electron microscopy(TEM), X-ray diffraction, reflective ultravio-let-visible spectrophotometry, and spectrofluorimetry. Calculations based on the SEM and TEM images showed that the sizes of the SnS -NPs immobilized on the AC were 30–70 nm. The prepared nanocomposite was used as a heterogeneous Lewis acid catalyst for the three-components one-pot synthesis of 4H-pyrano[2,3-c]pyrazole derivatives in ethanol at 80 ℃. The reactions were efficiently performed in the presence of the prepared catalyst in short reaction times, and gave the desired products in high yields. This catalyst can be easily recovered by simple filtration and recycled up to eight consecutive times without significant loss of its efficiency.Nasir Iravani Mosadegh Keshavarz Hossein Ali Shojaeian Kish Rasool Parandvar 2015催化学报2015,36,4:4

4MXene‑Graphene Composites:A Perspective on Biomedical Potentials显示文摘MXenes,transition metal carbides and nitrides with graphene-like structures,have received considerable attention since their first discovery.On the other hand,Graphene has been extensively used in biomedical and medicinal applications.MXene and graphene,both as promising candidates of two-dimensional materials,have shown to possess high potential in future biomedical applications due to their unique physicochemical properties such as superior electrical conductivity,high biocompatibility,large surface area,optical and magnetic features,and extraordinary thermal and mechanical properties.These special structural,functional,and biological characteristics suggest that the hybrid/composite structure of MXene and graphene would be able to meet many unmet needs in different fields;particularly in medicine and biomedical engineering,where high-performance mechanical,electrical,thermal,magnetic,and optical requirements are necessary.However,the hybridization and surface functionalization should be further explored to obtain biocompatible composites/platforms with unique physicochemical properties,high stability,and multifunctionality.In addition,toxicological and long-term biosafety assessments and clinical translation evaluations should be given high priority in research.Although very limited studies have revealed the excellent potentials of MXene/graphene in biomedicine,the next steps should be toward the extensive research and detailed analysis in optimizing the properties and improving their functionality with a clinical and industrial outlook.Herein,different synthesis/fabrication methods and performances of MXene/graphene composites are discussed for potential biomedical applications.The potential toxicological effects of these composites on human cells and tissues are also covered,and future perspectives toward more successful translational applications are presented.The current state-of-the-art biotechnological advances in the use of MXene-Graphene composites,as well as their developmental challenges and future prospects are also deliberated.Due to the superior properties and multifunctionality of MXene-graphene composites,these hybrid structures can open up considerable new horizons in future of healthcare and medicine.Ebrahim Mostafavi Siavash Iravani 2022Nano-Micro Letters2022,14,8:3
