Quantum Anomalies in Condensed Matter

Advanced Physics Research, EarlyView.
Quantum materials provide a fertile ground in which to test and realize quantum anomalies predicted by quantum field theory. Quantum anomalies need to be canceled globally, however, quantum states with a quantum anomaly can exist at the boundary of topological materials.

Activin A‐activated ALK4 induces pathogenic Th17 involved endothelial–mesenchymal transition in systemic lupus erythematosus‐associated pulmonary arterial hypertension

Arthritis &Rheumatology, Accepted Article.
Objective Autoimmune diseases, such as systemic lupus erythematosus (SLE), are associated with pulmonary arterial hypertension (PAH), a condition that can lead to heart failure. However, whether T cells also contribute to the occurrence of PAH in SLE, has not been clarified.

Can We Draw Conclusions on Supernova Shock Wave Propagation Using Short‐Lived Radioactive Isotopes?

Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.
ABSTRACT We run a three‐dimensional Galactic chemical evolution (GCE) model to follow the propagation of 53Mn (exclusively produced from type Ia supernovae, SNIa), 60Fe (exclusively produced from core‐collapse supernovae, CCSNe), 182Hf (exclusively produced from intermediate mass stars, IMSs), and 244Pu (exclusively produced from neutron star mergers ...

Spectroscopic Interrogation of Thiolate Hydrogen Bonding in the CO Sensor Protein CooA: Implications for Thiolate Ligation Stability and Cytochrome P450 Function

Chemistry – A European Journal, Accepted Article.
Cysteine (Cys) thiolate coordination is a unique ligation motif found in heme enzymes and small molecule sensors. Divergence between these two functional classes of heme thiolate proteins is a result of distinct hydrogen bonding interactions with the axial Cys(thiolate) ligand.

From Nanoparticles to Single Crystals of Al‐MOFs: Synergistic Coordination and pH Modulation, and Rapid Sorption Kinetics Assessment by Optical Calorimetry

Chemistry – A European Journal, Accepted Article.
The properties of metal‐organic frameworks (MOFs), such as sorption kinetics or mechanical and chemical stability, not only depend on their composition and chemical structure, but also on their crystal size and morphology. However, the tunability of the crystallite size of aluminum‐based MOFs (Al‐MOFs) is still a long‐standing challenge. In this study,

Effect of Chalcogen Interaction on the Structure of Methine‐Bridged Trichalcogenophenes

Chemistry – A European Journal, Accepted Article.
Polythienylenemethylidenes (PTMs) are promising conjugated polymers for organic electronics owing to their narrow bandgaps and extended π‐conjugation. However, their stereochemistry remains unexplored. In this study, methine‐bridged trithiophene and trifuran analogs were synthesized to investigate stereochemistry and chalcogen bonding effects.

Distributed remote antenna unit with selection‐based of (RoF‐IoT) paradigm: Performance improvement

IET Communications, EarlyView., 2022
Abstract Mixing the wireless medium with fiber optics can form a new communication system called a radio‐over‐fiber (RoF) network; it is a promising solution that can provide high bandwidth and a reliable connection between numerous sensors in wireless sensor networks (WSN) and the central office (base station) within a particular area.

Synthesis and Reactivity of Triphosphaallyl Cation stabilized by N‐Heterocyclic Carbenes

Chemistry – A European Journal, Accepted Article.
Reduction of the triphosphaallyl species 6[GaCl4] with GaI[Ga2Cl7] affords the imidazoliumyl‐substituted (L) bicyclo[2.1.1]‐triphosphane, 10[Ga2Cl7], featuring an unprecedented Ga2Cl5‐bridged P3 scaffold. Reactions of 10[Ga2Cl7] with nucleophiles (Cl‐ or NHC) result in rare, selective P–C bond cleavages, affording Ga2Cly‐substituted triphosphiranes ...
