Artemisinin‐Loaded Core‐Shell Microspheres Modulate Histone Lactylation to Remodel the Microenvironment for Cartilage Protection in Rheumatoid Arthritis

Advanced Healthcare Materials, EarlyView.
ART@PLGA@GH‐A microspheres are developed via microfluidic technology for intra‐articular delivery of artemisinin. The system remodels rheumatoid arthritis microenvironments by regulating metabolic and inflammatory disorders, reducing lactate‐driven histone lactylation and cellular senescence, while restoring cartilage homeostasis and protecting joint ...

Modified multicarrier sinusoidal pulse-width modulation for three-phase open-load five-level inverter [PDF]

Five-level voltage source inverter (VSI) is a power inverter topology generating a five-level output voltage waveform. This inverter topology can reduce harmonics distortion to be lower compared to a conventional two-level inverter.

Role of the Recombination Zone in Organic Light‐Emitting Devices

Advanced Materials, EarlyView.
This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

LEAD: Literature Enhanced Ab Initio Discovery of Nitride Dusting Layers for Enhanced Tunnel Magnetoresistance and Lower Resistance Magnetic Tunnel Junctions

Advanced Materials, EarlyView.
Magnetic tunnel junctions (MTJs) using MgO tunnel barriers face challenges of high resistance‐area product and low tunnel magnetoresistance (TMR). To discover alternative materials, Literature Enhanced Ab initio Discovery (LEAD) is developed. The LEAD‐predicted materials are theoretically evaluated, showing that MTJs with dusting of ScN or TiN on ...

Five-level inverter scheme for an open-end winding induction machine with less number of switches

, 2010
Higher level of inversion is achieved with a less number of switches in the proposed scheme. The scheme proposes a five-level inverter for an open-end winding induction motor which uses only two DC-link rectifiers of voltage rating of Vdc/4, a neutral ...

Measuring the Hall Effect in Hysteretic Materials

Advanced Materials, EarlyView.
The authors highlight common pitfalls in measuring the Hall effect: in hysteretic magnets, improper data processing can create signals that look exotic but are not real. This Perspective explains the origin of these artifacts and presents practical measurement strategies that help researchers identify reliable Hall responses in complex magnetic ...
