Bioengineered 3D Human Trabecular Meshwork Models for Outflow Physiology and Glaucoma Research [PDF]

Bioengineering
Primary open angle glaucoma (POAG) is one of the leading causes of irreversible blindness and is associated with dysfunction of the trabecular meshwork (TM), a three-dimensional (3D) structure that regulates aqueous humor outflow and, consequently ...

Unified centralised/decentralised frequency control structure for microgrids

IET Renewable Power Generation, 2021
When the microgrid (MG) operates in islanded mode, the frequency adjustment is performed through the secondary control. This control can be achieved through centralised, distributed or decentralised strategies.

Constant switching frequency control-based linear-assisted DC/DC regulator for photovoltaic solar-powered facilities [PDF]

2015 International Conference on Clean Electrical Power (ICCEP), 2015
Hybrid DC-DC regulators or linear–assisted DC-DC regulators are structures that combine both a linear voltage regulator and a switching DC-DC converter. The main objective of this hybrid topology is to converge, in a single circuit topology, the best of both alternatives: One the one hand, obtaining small voltage output ripple, which is typical of ...

Facile Fabrication of Defect-Controlled Graphene Oxide Membrane through Shear-Induced Alignment for Regulating Ion Transport

ACS Omega, 2022
Two-dimensional (2D) membranes enable ion-sieving through well-defined subnanoscale channels. In particular, graphene oxide (GO), a representative 2D material with a flexible structure, can be manufactured into various types of membranes, while defects such as pores and wrinkles are readily formed through self-aggregation and self-folding during ...
