Summary: In this study, hybrid ruthenium-decorated superparamagnetic iron oxide nanoparticles were designed as contrast agents for both magnetic resonance imaging (MRI) and X-ray fluorescence computed tomography (XFCT). These nanoparticles were synthesized through a one-pot polyol hot injection method. In vivo preclinical studies showed the possibility of correlative bioimaging using these contrast agents. The complementary nature of MRI and XFCT allowed for accurate localization and high specificity and resolution in nanoparticle detection, suggesting potential applications for early tumor diagnosis, improved long-term treatment monitoring, and enhanced radiotherapy planning.

Summary: This study investigates the influence of the polarity of polymer matrices on persistent room-temperature phosphorescence (pRTP). It is discovered that intense phosphorescence emission can be achieved in highly polar matrices such as polyacrylic acid (PAA). The dipole-dipole interaction between the polar fluorophore and polar matrix is proposed to stabilize the excited state and facilitate the generation of efficient room-temperature phosphorescence emissions.

Summary: Donor-acceptor heterostructures using organic-inorganic halide perovskites, two-dimensional transition metal dichalcogenides, pi-conjugated organic small/macro molecules, and quantum dots are promising platforms for exciton-based photonics and optoelectronics. Hetero-interlayer excitons and hetero-intermolecular excitons formed through optical and/or electrical charge transfer in various heterostructures are important quasi-particles for light emission, detection, and harvesting systems.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.

Summary: In this study, a new spin-gapless semiconductor material CoFeMnSn is reported, and its stable structure and spin-polarized band structure are determined through experimental realization and theoretical calculations. The compound exhibits a high ferromagnetic transition temperature, making it excellent for room temperature applications. The nearly temperature-independent resistivity, conductivity, and carrier concentration of the compound, adherence to the Slater-Pauling rule, and the high intrinsic anomalous Hall conductivity achieved through hole doping further confirm its spin-gapless semiconductor nature. Additionally, the compound's SGS and topological properties make it suitable for spintronics and magneto-electronics devices.
