Summary: This study investigates the superconducting properties of LiFeP and LiFeAs through nuclear magnetic resonance (NMR) studies, revealing differences in their superconducting behaviors. The saturation of λ(L) in LiFeAs indicates nodeless superconducting gaps, while the absence of saturation in LiFeP suggests the presence of nodes in the superconducting gap function. Strong spin fluctuations with diffusive characteristics are also observed in LiFeP, similar to some cuprate high temperature superconductors.

Summary: In this study, we computed the superconducting transition temperature (Tc) of iron-based superconductors using two existing models and tested their validity for predicting the Tc of FeSe monolayers. Our results show that the model, which takes into account the amplifying effect of antiferromagnetism and electron-phonon coupling, agrees well with experimental data. Furthermore, we found that interfacial effects may contribute to the observed Tc enhancement in FeSe monolayers.

Summary: The evolution of superconductivity in LiFeAs with respect to pressure or strain is still unclear, but this study found that different orientations of local wrinkles on the surface have varying effects on the superconducting states, suggesting that directional pressure may play an important role in iron-based superconductivity.

Summary: Voltage control of magnetic order is essential for energy-efficient spintronic applications, and solid-state hydrogen gating allows for reversible ferrimagnetic order control, external-field-free 180 degrees magnetic switching, and ferrimagnetic spin texture manipulation. In this study, the use of electric field-induced hydrogen loading/unloading in GdCo shifts the magnetic compensation temperature and enables control of the dominant magnetic sublattice. Additionally, the weakening of antiferromagnetic exchange coupling results in reversible gate voltage-induced net magnetization switching and generation of ferrimagnetic spin textures.

Summary: The study shows that CaAFe(4)As(4) can achieve a superconducting transition temperature of 31-36 K without doping. The introduced alkali metals can induce hole doping and chemical pressure effects, which can affect the superconducting transition temperature by changing the number of electrons and the structure of the FeAs conductive layer.

Summary: Spin-resolved spectroscopic studies revealed the Yu-Shiba-Rusinov (YSR) bound states on the surface of the topological superconductor FeTe0.55Se0.45 induced by Fe atoms. Zero-energy bound states were observed for some of the adsorbed Fe atoms, with the absence of spin signature indicating the lack of Majorana bound states associated with Fe adatoms on FeTe0.55Se0.45.

Summary: We report the discovery of superconductivity on the border of antiferromagnetic order in a quasi-one-dimensional material RbMn6Bi5 under high pressures. The phase diagram of the material shows similarities to many magnetism-mediated superconductors. The study found that with increasing pressure, the antiferromagnetic ordering transition is enhanced and then suppressed, leading to the emergence of superconductivity with a relatively high critical temperature.

Summary: An investigation on the spin resonance mode in optimally hole-doped iron-based superconductor Ba0.67K0.33Fe2As2 revealed a unique energy dispersion phenomenon, suggesting that the spin resonance may not be restricted by the superconducting gaps in multi-band systems. This breaks through the conventional understanding and poses new challenges in the study of superconductivity in iron-based materials.

Summary: The study reveals localized superconducting states in a calcium-iron-based superconductor using low-temperature scanning tunneling microscopy and spectroscopy. The competition between local strain of praseodymium dopants and defect-induced local magnetic moments affects the superconductivity. These superconducting states exist at the nanoscale near the praseodymium dopants and are not influenced by surface reconstruction or defects.

Summary: This study investigates the crystallization and growth of anisotropic nanocrystals into distinct superlattices in real time, providing kinetic details and designer parameters for the scale-up fabrication of functional materials. By studying the assembly of octahedral PbS NC blocks, the researchers found that NCs preferentially self-assembled into an orientation-disordered face-centered cubic superlattice, which later transformed into a body-centered cubic superlattice with single NC-orientational ordering across individual domains. Such insights and defined parameters allowed for the scalable fabrication of large/single bcc supercrystals with coherent ordering of NC translation and atomic plane orientation.

Summary: The A-site-ordered perovskite PbHg3Ti4O12 is the only known quadruple perovskite that undergoes a phase transition from a high-temperature centrosymmetric paraelectric phase to a low-temperature non-centrosymmetric ferroelectric phase under high pressure synthesis. It bridges the gap between simple ABO(3) perovskites and A-site-ordered AA'3Ti4O12 perovskites, exhibiting both displacive ferroelectricity and unique structural coordination.

Summary: The nucleation and dissociation of CO2 hydrate in the inter- and intra-particle pores of dioctahedral smectite particles are affected by the layer charge distribution and type of exchangeable cations in the smectite, altering the structural ordering of water molecules. CO2 diffusion into intra-particle pores enhances the formation of clathrate-like structures but does not increase the structural ordering of water molecules. Increasing temperature or adding electrolytes accelerates CO2 hydrate dissociation in smectite particles.

Summary: Researchers have shown great interest in two-dimensional crystals due to their thickness-dependent electronic and optical properties. By investigating the Raman and photoluminescence spectra of free-standing monolayer and bilayer MoS2, it was found that electronic and crystal phase transitions occur at around 6 GPa and 16 GPa in bilayer MoS2, but not in the monolayer. These pressure-induced features provide insights into the importance of interlayer interactions in modifying the optical properties of MoS2 and other 2D materials.

Summary: The study reported a pressure-induced phase transition and a dome-shaped superconducting phase in van der Waals layered NbIrTe4, with the highest critical temperature observed at approximately 5.8 K under a pressure of about 16 GPa. Anisotropic transport near the superconducting state was also observed, possibly due to the spatial modulation of interlayer Josephson coupling.

Summary: Cooperative Jahn-Teller (JT) distortion, combined with electromagnetic lattice coupling, plays a crucial role in numerous phenomena in materials science. While JT distortion is common in high-spin 3d4 and 3d9 configurations in octahedral complexes, large distortions resulting from the degeneracy lifting of t2g orbitals have rarely been observed. In this study, we report the discovery of pressure-induced cooperative JT effect in MnTe, which is accompanied by a significant volume collapse and a collapse of magnetic moment. First-principles calculations suggest that the lifting of t2g orbital degeneracy in Mn2+(d5) due to weakened p-d hybridization and enhanced d state localization induces the cooperative JT effect and triggers electromagnetic lattice coupling. These findings present a new mechanism for cooperative JT distortion via pressure-induced ligand distortion in antiferromagnetic materials.

Summary: This study reports the discovery of richer transport properties, including abnormal properties and superconductivity, in high-pressure HgTe crystals. By pressure-tuning, a series of high-pressure phases were observed in a 400 nm thick crystal, and superconductivity emerged after the semiconductor-to-metal transition. Density functional theory calculations confirmed the contribution of surface-dominated topological band structure to these properties.

Summary: Organic solar cells are a promising development direction due to their low cost, light weight, and flexibility. However, their power conversion efficiency is limited by the difficulty in regulating the size of their bandgap. In this study, a new organic molecule TPEPA was synthesized and its luminescence performance and polymerization under high pressure were investigated. The results showed that the TPEPA molecule underwent amorphization and polymerization under high pressure, leading to a reduced bandgap within the optimal range for solar cell materials. These findings provide a potential method for large-scale synthesis of novel organic solar cell materials.
