Improvement of DSOGI PLL Synchronization Algorithm with Filter on Three-Phase Grid-connected Photovoltaic System

open access: yesJurnal Elektronika dan Telekomunikasi, 2018
Synchronous Reference Frame Phase Locked Loop (SRF PLL) has been widely used for synchronization three-phase grid-connected photovoltaic (PV) system. On the grid fault, SRF PLL distorted by negative sequence component and grid harmonic that caused an ...

Cavity Microelectrode Arrays for Electrical Recordings From Neurons

open access: yesAdvanced Electronic Materials, EarlyView.
Microelectrode arrays (MEAs) are used to study electrophysiological activity. However, their signals are small with high noise. By adding a 100‐nanometer‐high cavity above the electrode, which reduces impedance without affecting resolution, we improve signal quality.

Donor–Acceptor Covalent Organic Framework Enables Ambipolar Charge Storage in Aluminum‐Ion Energy Storage

open access: yesAdvanced Energy Materials, EarlyView.
A donor–acceptor covalent organic framework is designed as an ambipolar cathode for aluminum‐ion energy storage. The crystalline, microporous architecture enables intrinsic charge transport without conductive additives. Multi‐electron redox activity at donor and acceptor sites supports high capacity, excellent stability, and efficient reversible ...

Optimization of CEST MRI Reporter Protein Design Using Cation‐Pi Networks

open access: yesChemistry – A European Journal, EarlyView.
A novel engineering approach can produce reporter proteins for cell and viral therapy tracking with unique magnetic resonance imaging (MRI) signatures, detectable with chemical exchange saturation transfer (CEST). We discover how cation‐π interactions between amino acid groups can help us fine‐tune magnetic resonance properties for noninvasive ...

Protocol for Reconstituting Adaptor‐Mediated Activation of Full‐Length Kinesin‐1

open access: yesCytoskeleton, EarlyView.
ABSTRACT Kinesin‐1 is a member of the kinesin superfamily that plays an essential role in intracellular cargo transport. In the absence of cargo, Kinesin‐1 exhibits low motor activity due to autoinhibition. Multiple studies have demonstrated that adaptor proteins, which link cargos to Kinesin‐1, can activate Kinesin‐1 by releasing the autoinhibition ...

Oscillation suppression strategy for direct drive wind power system based on voltage feedforward compensation for phase locked loop

open access: yesCSEE Journal of Power and Energy Systems
Due to the fact that the impedance of grid interacts with that of direct-drive wind turbines under weak grid, the direct-drive wind power system (DDWPS) possesses the risk of power oscillation.
