A Generalized Modular Multilevel Current Source Inverter

Autor: E. Seifi Najmi, A. Ajami, A. H. Rajaei

Publikováno v: Journal of Operation and Automation in Power Engineering, Vol 5, Iss 2, Pp 181-190 (2017)

This paper proposes a novel topology of multilevel current source inverter which is suitable to apply in low/medium voltage. The proposed topology is capable of producing desirable bidirectional output current levels. Furthermore, it can employ symme

Explantation of an ALTO abdominal stent graft

Autor: Carl T. Schoephoerster, BS, Mohammad H. Rajaei, MD, Peter J. Rossi, MD

Publikováno v: Journal of Vascular Surgery Cases and Innovative Techniques, Vol 10, Iss 2, Pp 101416- (2024)

Explantation of traditional infrarenal aortic endografts has been previously described, and explanation of aortic endografts with standard suprarenal fixation at our center has been well defined. However, to the best of our knowledge, no cases have b

Left-sided inferior vena cava implications for cardiopulmonary bypass cannulation in open thoracoabdominal aortic aneurysm repair

Autor: Carl T. Schoephoerster, BS, Mohammad H. Rajaei, MD, Laura S. Gonzalez, MD, Kellie R. Brown, MD, Michael E. Mitchell, MD, Peter J. Rossi, MD

Publikováno v: Journal of Vascular Surgery Cases and Innovative Techniques, Vol 9, Iss 2, Pp 101166- (2023)

A left-sided inferior vena cava poses a unique challenge when cannulating for cardiopulmonary bypass during thoracoabdominal aortic aneurysm repair, and how to effectively and safely do so has not been previously described. A 51-year-old woman with a

Electro-osmotic flow and the limiting current in alkaline water electrolysis

Autor: J.W. Haverkort, H. Rajaei

Publikováno v: Journal of Power Sources Advances, Vol 6, Iss , Pp 100034- (2020)

Under alkaline conditions, hydroxide ions can deplete at the anode of a water electrolyser for hydrogen production, resulting in a limiting current density. We found experimentally that in a micro-porous separator, an electro-osmotic flow from anode

Design of membraneless gas-evolving flow-through porous electrodes

Autor: J.W. Haverkort, H. Rajaei, A. Rajora

Publikováno v: Journal of Power Sources, 491

Flow-through electrolyzers, with flow parallel to the current, are used in a wide range of industrial applications. The presence of flow avoids concentration gradients but can also be used to separate evolved gases, allowing membrane-less operation.

Voltage losses in zero-gap alkaline water electrolysis

Autor: J.W. Haverkort, H. Rajaei

Publikováno v: Journal of Power Sources, 497

Reducing the gap between the electrodes and diaphragm to zero is an often adopted strategy to reduce the ohmic drop in alkaline water electrolyzers for hydrogen production. We provide a thorough account of the current–voltage relationship in such a

Compact monopolar electrochemical stack designs using electrode arrays or corrugated electrodes

Autor: J.W. Haverkort, H. Rajaei

Publikováno v: Electrochimica Acta, 332

A new compact electrode architecture with hollow pillar-shaped anodes and cathodes arranged in a ‘checkerboard’ pattern is analysed and shown to be equivalent to a particular arrangement of corrugated plate electrodes. Because all four sides of t
