Vertically oriented nanoporous block copolymer membranes for oil/water separation and filtration
(
Royal Society of Chemistry
, 2020 , Article)
The separation of oil from water and filtration of aqueous solutions and dispersions are critical issues in the processing of waste and contaminated water treatment. Membrane-based technology has been proven as an effective ...
Brief Report: Polymorphisms in TNF-α/TNFR1 Pathway Genes Are Associated With CD4+ T-Cell Recovery in HIV-1–Infected Individuals on Antiretroviral Therapy
(
NLM (Medline)
, 2021 , Article)
Background:
Antiretroviral therapy (ART) is an important hallmark of HIV-1 treatment, enabling viral load suppression to undetectable levels and CD4+ T-cell recovery. However, some individuals do not recover the CD4+ ...
Novel level-shifted PWM technique for cascaded multilevel quasi-impedance source inverter
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
In a multilevel quasi-impedance source inverter (qZSI), phase-shifted carrier pulsewidth modulation (PS-PWM) is the most popular modulation method as it offers advantages such as simple implementation and evenly powered ...
High gain switched-inductor-double-leg converter with wide duty range for dc microgrid
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
In a dc microgrid, efficient high gain converters are needed to raise the voltage level of low voltage power sources such as photovoltaic, fuel cells, etc. In this article, a high-gain switched-inductor-double-leg converter ...

Phase Reconfiguring Technique for Enhancing the Modulation Index of Multilevel Inverter Fed Nine-Phase im Drive
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
In this article, a multilevel inverter (MLI) scheme is proposed for four-pole (4-pole), nine-phase (9-phase) induction motor (IM) drives with improved dc bus utilization as well as reduced device count. The proposed MLI ...
Novel Level-Shifted PWM Technique for Equal Power Sharing among Quasi-Z-Source Modules in Cascaded Multilevel Inverter
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
Phase-shifted pulsewidth modulation (PS-PWM) is a well-known switching technique for quasi-Z-source (qZS)-based cascaded multilevel inverters (qZS-CMI). PS-PWM ensures equal power distribution (among operating modules) and ...
