Circulating Current Suppression Method of Modular Multilevel Converter Based on SOGI Under Unbalanced Grid Conditions

工程科学与技术, 2023
The design and analysis of modular multilevel converter (MMC) is usually carried out under the condition of power grid balance, but the AC power grid is unbalanced in actual operation.

Wavelength‐Dependent Photobiomodulation Regulates Macrophage Polarization via Mitochondrial Dynamics and Metabolic Reprogramming

Advanced Science, EarlyView.
Light wavelength encodes distinct macrophage fates through mitochondrial and metabolic remodeling. Red 625 nm irradiation induces glycolysis, mitochondrial fission, and M1 polarization, whereas near‐infrared 850 nm irradiation promotes fatty acid oxidation, mitochondrial fusion, and M2 polarization.

Model predictive control strategy for NPC grid‐connected inverters in unbalanced grids

Electronics Letters, 2016
A model predictive control (MPC) strategy for a three‐phase three‐level neutral point clamped (NPC) grid‐connected inverter is discussed. Conventional two‐level inverters are effective when a symmetric fault occurs. But when a three‐phase unbalanced fault occurs, they will generate errors and introduce delay in the power system because of the complex ...

Highly Reversible Zinc Anode Enabled by a Thiourea‐Derived Protective Layer for Alkaline Zinc Batteries

Advanced Science, EarlyView.
A ZnS/carbon nitride (ZnS/CN) protective coating is constructed on Zn anodes via ultrasonic spray coating, enabling uniform and stable Zn stripping/plating, suppressing dendrite formation, and mitigating parasitic side reactions, resulting in a prolonged cycling lifespan and high reversibility of the Zn anode in alkaline Zn–air batteries. ABSTRACT Zinc‐

Molecular Engineering Mediated Interfacial Assembly as an Artificial Extracellular Matrix Remolds Bacteria With Enhanced Abiotic Resilience

Advanced Science, EarlyView.
A biomimetic artificial extracellular matrix is assembled directly on Pseudomonas fluorescens by co‐assembling amyloid‐like lysozyme and alginate at the cell surface. This conformal nanocoating acts as both a hydration buffer and a physiological priming layer, markedly enhancing desiccation tolerance, seed adhesion, storage stability, and biocontrol ...

Circulating Amino Acid Network Remodeling Reveals Systemic Metabolic Reprogramming Predictive of Colorectal Cancer Recurrence and Metastasis

Advanced Science, EarlyView.
Blood‐based amino acid patterns measured by 19F NMR reveal hidden metabolic changes in colorectal cancer. By analyzing how these amino acids interact as a network, machine learning models identify patients at higher risk of recurrence and metastasis.

Single‐Cell Reveal GALNT7‐Dependent Ferroptosis Suppression as a Mechanism of Immunotherapy Resistance in Non‐Small Cell Lung Cancer

Advanced Science, EarlyView.
Integrated clinical and mechanistic analyses identify GALNT7 as a ferroptosis‐suppressive regulator associated with immunotherapy resistance in non‐small cell lung cancer. GALNT7 depletion promotes lipid peroxidation, mitochondrial dysfunction, and ferroptosis, enhances CD8+ T‐cell activation and IFN‐γ production, and sensitizes tumors to PD‐1 blockade,
