Halide‐Dependent Photoluminescence and Heavy‐Atom Effects in Low‐Melting Organic–Inorganic Manganese Halides

Advanced Functional Materials, EarlyView.
Two pyridinium‐based ionic liquid templated hybrid manganese halides, (C4Py)2[MnCl4] and (C4Py)2[MnBr4], display similar bulk structures but show significantly different photoluminescence behaviors due to the bromine heavy‐atom effect. Their stable local Mn environments remain intact even in the molten state, allowing applications such as luminescence ...

LL‐37 Driven Phase Transition and Stacking in Oligolamellar Gram‐Negative Bacterial Membrane Models

Advanced Functional Materials, EarlyView.
This work establishes oligolamellar bacterial membrane models to investigate how LL‐37 disrupts the complex dual‐bilayer architecture of Gram‐negative bacteria. Combining SAXS, cryo‐TEM, electrophoretic mobility measurements, and coarse‐grained simulations, it reveals cardiolipin‐driven phase transitions leading to bicelle‐like structures and membrane ...

Dynamic Effect of Input-Voltage Feedforward in Three-Phase Grid-Forming Inverters

Energies, 2020
Grid-connected and grid-forming inverters play essential roles in the utilization of renewable energy. One problem of such a converter system is the voltage deviations in the DC-link between the source and the inverter that can disrupt the inverter ...

Aqueous Two‐Phase Bioinks for Discrete Packing and Compartmentalization of 3D Bioprinted Cells

Advanced Healthcare Materials, EarlyView.
Aqueous two‐phase systems (ATPS) enable the formation of biomimetic interfaces crucial for tissue engineering. However, clinical translation remains limited by the challenge of precisely controlling cellular compartmentalization. Here, we developed ATPS biomaterial inks for 3D bioprinting allowing tuneable droplet formation via NaCl modulation.

Control strategy for seamless transition from islanded to interconnected operation mode of microgrids

Journal of Modern Power Systems and Clean Energy, 2017
Microgrids can operate either interconnected to the utility grid or disconnected forming an island. The transition between these modes can cause transient overcurrents or power oscillations jeopardizing the equipment safety or the system stability.

Spherical Skin Model: Stratified Co‐Culture of Fibroblasts and Keratinocytes on Spherical Beads Toward Compound Screening

Advanced Healthcare Materials, EarlyView.
Models of the human skin must combine the relevant biological contents and suitable biomaterials with the correct spatial organization. Performing compound screening on such in vitro models also requires fast and reproducible production methods of the models.

Output Impedance Control Method of Inverter-Based Distributed Generators for Autonomous Microgrid

Energies, 2017
The droop method is the most favorable alternative in microgrid implementations for autonomous control of grid-forming inverter-based distributed generators (DGs) connected in parallel. However, the dynamic characteristic of the conventional droop method

Adaptive Fault Detection for Grid-Forming Inverters

IEEE Access
This work introduces a residual-based adaptive threshold for detecting faults in grid-forming inverters in AC microgrids islanded from the main grid. The inverters are modeled as a nonlinear system with one-sided Lipschitz nonlinearities and modeling uncertainties.
