Suppression of Spin-Orbit Torque Switching by the Magnetic Proximity Effect.

Functional magnetic multilayers are particularly interesting for enabling many emerging spintronic physics, including spin-orbit torque (SOT), magnetic proximity effect (MPE), and perpendicular magnetic anisotropy (PMA), among many others. A comprehension of these spintronic phenomena is vital for the development of advanced spintronic materials and devices. Here, we investigate the interplay between the MPE and the current-induced SOT switching in the perpendicularly magnetized Pt/[Co/Pd] multilayers (with being the number of repetitions).

The regulation of IgA expression is crucial for maintaining mucosal immune homeostasis, providing a vital defense mechanism against pathogens at mucosal surfaces. However, the intricate mechanisms governing IgA class-switch recombination and its dysregulation in diseases such as inflammatory bowel disease remain a significant challenge in the field. Our study delves into the significance of IgA regulation in mucosal immunity, focusing on the N-acetylcytidine (acC) in NIK mRNA by NAT10 in B cells.

Magnetic Order Induced Chiral Phonons in a Ferromagnetic Weyl Semimetal.

Chiral phonons are vibrational modes in a crystal that possess a well-defined handedness or chirality, typically found in materials that lack inversion symmetry. Here, we report the discovery of chiral phonon modes in the kagome ferromagnetic Weyl semimetal Co_{3}Sn_{2}S_{2}, a material that preserves inversion symmetry but breaks time-reversal symmetry. Using helicity-resolved magneto-Raman spectroscopy, we observe the spontaneous splitting of the doubly degenerate in-plane E_{g} modes into two distinct chiral phonon modes of opposite helicity when the sample is zero-field cooled below the Curie temperature in the absence of an external magnetic field.

Antiferromagnetic quantum anomalous Hall effect under spin flips and flops.

The interplay between nontrivial band topology and layered antiferromagnetism in MnBiTe has opened a new avenue for exploring topological phases of matter. The quantum anomalous Hall effect and axion insulator state have been observed in odd and even number layers of MnBiTe, and the quantum metric nonlinear Hall effect has been shown to exist in this topological antiferromagnet. The rich and complex antiferromagnetic spin dynamics in MnBiTe is expected to generate new quantum anomalous Hall phenomena that are absent in conventional ferromagnetic topological insulators, but experimental observations are still unknown.

Extracellular vesicles-derived MicroRNA-145-5p is upregulated in the uterine fluid of women with endometriosis and impedes mouse and human blastocyst development.

Previous work indicated that the implantation and pregnancy rates of women with endometriosis are lower than those of healthy women during in-vitro fertilisation and embryonic transfer. And there are numerous microRNAs (miRNAs) in human uterine luminal fluid (ULF), some of which are associated with early preimplantation development of embryos. In our study, we sought to determine whether miRNAs in the ULF are differentially expressed between women with and without endometriosis and to uncover the association of miRNAs with the development potential of blastocysts.

However, the processes involved in the burial and generation of formation water remain not fully understood.

Electrical Excitation and Detection of Chiral Magnons in a Compensated Ferrimagnetic Insulator.

Magnon chirality refers to the precessional handedness of magnetization around the external magnetic field, which is fixed as right-handed in ferromagnets. Compensated ferrimagnets accommodate parallel and antiparallel configurations of net magnetization and angular momentum, and thus serve as an ideal platform for studying magnon chirality. Through performing spin-torque ferromagnetic resonance experiments, we experimentally study the reversal of low-frequency magnon chirality across the magnetization and angular momentum compensation temperatures in a Gd_{3}Fe_{5}O_{12}/Pt bilayer.

Comprehensive evaluation of nitrogen contamination in water ecosystems of the Miyun reservoir watershed, northern China: distribution, source apportionment and risk assessment.

Miyun Reservoir plays a vital role as a source of drinking water for Beijing, however it grapples with nitrogen contamination issues that have been poorly understood in terms of their distribution, source, and associated health risks. This study addresses this knowledge gap by employing data on nitrate nitrogen (NO-N), chloride (Cl), dual isotopic compositions of NO (δN-NO and δO-NO) data in water ecosystems, systematically exploring the distribution, source and health risk of nitrogen contaminants in Miyun reservoir watersheds. The results showed that over the past 30 years, surface water runoff has exhibited a notable decrease and periodic fluctuations due to the combined influence of climate and anthropogenic activities, while the total nitrogen (TN) concentration in aquatic ecosystems presented an annual fluctuating upward trend.

Effects of Sulfate Ions on Crude Oil Adsorption/Desorption on Carbonate Rocks: Experimental and Molecular Simulations.

In the background of the strong oil wettability and low production by water flooding in carbonate reservoirs, low-salinity water containing sulfate ions can significantly change the surface wettability of carbonate rocks and thus increase the sweeping area; however, the absorption and desorption mechanisms of the oil film in the carbonate rock surface remain unclear. This paper analyzed the wettability alternation of carbonate rocks' surface in pure water and sodium sulfate solution. At the same time, MD (Materials Studio) software was used to simulate the formation process of the oil film and the effect of sulfate ions on the desorption of the oil film on the surface of carbonate rocks.

Current induced spin-orbit torque (SOT) holds great promise for next generation magnetic-memory technology. Field-free SOT switching of perpendicular magnetization requires the breaking of in-plane symmetry, which can be artificially introduced by external magnetic field, exchange coupling or device asymmetry. Recently it has been shown that the exploitation of inherent crystal symmetry offers a simple and potentially efficient route towards field-free switching.
