Emergent Magnetic Structures at the 2D Limit of the Altermagnet MnTe

Advanced Functional Materials, EarlyView.
Renewed interest in MnTe has emerged due to its intriguing altermagnetism, a newly identified form of magnetism distinct from conventional ferro‐, antiferro‐, or paramagnetism. By combining magnetic X‐ray absorption spectroscopy, scanning tunnelling microscopy, and first‐principles theory, this study reveals that thinning MnTe to the 2D limit ...

Cryogenic Focused Ion Beam Milling to Investigate the Anisotropic Magnetotransport Properties of Bismuth Microcrystals

Advanced Functional Materials, EarlyView.
The highly anisotropic Fermi surface of bismuth results in variations in magnetotransport properties across different crystallographic directions, which can be characterized by studying microcrystals. To avoid the observed surface melting under room temperature Focused Ion Beam (FIB) irradiation, two low‐temperature FIB fabrication methods are proposed

Spiro‐Phenothiazine Hole‐Transporting Materials: Unlocking Stability and Scalability in Perovskite Solar Cells

Advanced Materials, EarlyView.
Fluorene‐functionalized spiro‐phenothiazine (PTZ‐Fl) exhibits strong Li+ affinity and thermal stability, enabling a PCE of 25.75% in small‐area cells and 22.07% in 25 cm2 modules. Under ISOS‐L3 conditions, PTZ‐Flbased devices retain over 80% efficiency after 1000 hours, demonstrating superior stability and scalability compared to spiro‐OMeTAD for next ...

Enhanced mitochondrial activity reshapes a gut microbiota profile that delays NASH progression

Hepatology, EarlyView., 2022
Improved mitochondrial activity, due to the lack of methylation‐controlled J protein (MCJ), creates a specific microbiota signature that when transferred through cecal microbiota transplantation delays NASH progression by restoring the gut‐liver axis and enhancing hepatic fatty acid oxidation.
