Summary: This paper demonstrates the room-temperature thermal modulation in 2.5 mm-thick Pb(Mg1/3Nb2/3)O-3-xPbTiO(3) (PMN-xPT) single crystals. Through the use of advanced poling conditions and a systematic study on composition and orientation dependence, a range of thermal conductivity switching ratios, with a maximum of approximately 1.27, is observed. The simultaneous measurements of piezoelectric coefficient (d(33)), domain wall density using polarized light microscopy (PLM), and birefringence change using quantitative PLM reveal an increase in domain wall density at intermediate poling states (0< d(33)< d(33(max)) compared to the unpoled state.

Summary: Spin density functional theory calculations were used to investigate exchange interactions in hexagonal YMnO3 and LuMnO3 multiferroic compounds, with the inclusion of a Hubbard U correction. The intraplane superexchange interaction was found to decrease with increasing U-eff, with the best agreement with experiment found for U-eff values between 2.55 and 4.0 eV. Topological analysis of the electron density indicated an increase in closed-shell interaction of bonds with increasing U-eff. Additionally, both interplane and intraplane super-superexchange interactions were computed and compared with previous studies.

Summary: Magnetic domain wall (DW)-based logic devices offer superior performance characteristics for emerging electronics applications. However, reliance on an external magnetic field limits their implementation, especially in large-scale applications. Multiferroic systems combining piezoelectric substrates with ferromagnets offer a potential solution, enabling control of magnetization through an electric field. By exploiting strain-induced magnetization anisotropy tilting, all-electrical logic operations can be performed, paving the way for scalable memory-in-logic applications.

Summary: This study shows that the thin-film Aurivillius phase Bi6TixFeyMnzO18 is an ideal material platform for domain wall and vortex topology-based nanoelectronic devices. The presence and structure of charged domain walls are revealed using atomic-resolution electron microscopy. Moreover, it is found that polar vortex-type topologies also form at out-of-phase boundaries of stacking faults. The study suggests the potential for strain engineering to control the formation of polar vortex topology in other multiferroic thin films.

Summary: The effects of Zr and Mo doping on YMnO3 were studied, including their influence on the structure, microstructure, oxidation state, and dielectric properties. It was found that Mo doping induced a phase transition in YMnO3 and resulted in changes in grain morphology and size. XPS analysis confirmed the presence of different manganese species and doping elements. The dielectric properties exhibited relaxor behavior, which was attributed to the interstitial oxygen absorption mechanism.

Summary: In multiferroic heterostructures, electric-field manipulation of spin waves has been demonstrated, showing the potential for controlling the amplitude and phase of spin waves. The electric-field effects are mediated by strain coupling between alternating ferroelectric stripe domains, leading to reversible motion of ferroelectric domain walls and pinned anisotropy boundaries that turn the spin-wave signal on and off. Additionally, linear electric-field tuning of the spin-wave phase by altering the width of the coupled stripe domains has been achieved, providing a new route towards energy-efficient reconfigurable magnonics.

Summary: We observe a thermal Hall conductivity with a large amplitude in a non-magnetic elemental insulator. The presence of this phenomenon in various insulators suggests a common mechanism, although the absolute amplitude varies greatly. The lack of correlation between the thermal Hall angle and the phonon mean-free-path imposes constraints on theoretical explanations.

Summary: Water redistribution has a profound impact on the function of dryland ecosystems. Biological soil crusts (BSCs or biocrusts), which cover a large portion of arid land soil surface, have conflicting effects on water redistribution at a regional scale. This study clarified the effects of different biocrusts on soil hydraulic properties in the Tengger Desert. The results showed that biocrusts significantly altered soil hydraulic properties, including water holding capacity, soil hydrophobicity, water sorptivity, and unsaturated hydraulic conductivity. Understanding the role of biocrusts in hydraulic properties can help improve our understanding of soil water distribution, movement, and retention in the area.

Summary: The purpose of this study was to evaluate the biological effects of cancer stem cells (CSCs) irradiated by charged particle, including proliferation, invasion, migration, and changes in the molecular level. The results showed that CSCs have obvious radio-resistance compared with non-CSCs, and charged particle irradiation or in combination with drugs could overcome this resistance, specifically manifested in inhibiting CSCs' proliferation, invasion, migration, and causing more and harder to repair DNA double-stranded breaks (DSB) of CSCs.

Summary: Efficient and environmentally friendly ferroelectric BSLNT ceramics were prepared and used as tribocatalysts for organic degradation. The catalytic capability was improved by enhancing the ferroelectric properties, leading to 92% RhB degradation after 2 hours. Further enhancement of the catalytic efficiency was achieved through electrical poling, reaching 96.8% degradation in 2 hours. Under the synergistic effect of illumination and friction, the degradation efficiency of RhB reached 95.2% after 30 minutes. This study demonstrates the application of highly efficient ferroelectric tribocatalysts for dye wastewater degradation, expanding the use of ferroelectric materials in catalysis.

Summary: The CYP76 subfamily, which belongs to the CYP superfamily, is crucial for phytohormone biosynthesis and response to environmental stresses in plants. Genome-wide analysis of the CYP76 subfamily in seven AA genome species revealed three groups, with Group 1 having the largest number of members. Analysis of cis-acting elements showed a high number of elements related to jasmonic acid and light response. Gene duplication analysis indicated expansion mainly through SD/WGD and tandem forms, with strong purifying selection during evolution. Expression pattern analysis showed that OsCYP76s exhibit restricted expression patterns in leaves and roots. qRT-PCR analysis of CYP76s under abiotic stresses revealed specific response patterns and functional divergence between japonica and indica rice. These findings provide valuable insights into the functional diversity and evolution of the CYP76 subfamily and have implications for improving stress tolerance and agronomic traits in rice.

Summary: It was found that only tetrahedral (Td) sites are highly active in Co2Mo3O8 while the octahedral (Oh) sites are activated by introducing Fe. The dual activation of different sites improves the efficiency of the oxygen evolution reaction (OER) and the unique structure increases the number of active sites, produces synergistic effects, optimizes the adsorption of intermediates, and creates an unobstructed spin channel for electron transfer.
