Summary: Beta-Cyclodextrin (CD) is used as a carrier for antimicrobial and anticancer polymer dots (PDs), and also studied as a fluorescent sensor for metal detection. The study found that under basic conditions, synthesized PDs formed controllable clusters, while under acidic conditions, smaller non-fluorescent carbon nanoparticles were obtained. Fluorescence intensity of the PDs synthesized under basic conditions was affected by pH, and higher compared to those under acidic conditions. The PDs were also used as fluorescent detectors for silver ions in water.

Summary: Due to the immunosuppressive tumor microenvironment (ITM), immune checkpoint blockade and vaccine therapies often lead to an inadequate immune response. However, the activation of the STING pathway through the use of multifunctional hybrid exosomes has shown promising results in enhancing cancer immunotherapy. These hybrid exosomes can induce polarization of tumor-associated macrophages (TAMs) to the M1 phenotype, release DNA-targeting agents to induce DNA damage, and stimulate cGAS/STING activation, resulting in significant anti-tumor and antimetastatic efficacy.

Summary: Fabricating a multifunctional superhydrophobic cotton fabric with antibacterial properties is highly desirable but rare. This study proposes a one-step redox reaction strategy based on PMHS and [Ag(NH3)(2)](+) ions to endow cotton fabrics with superhydrophobic and antibacterial properties. The modified cotton fabrics exhibit high repellency against common liquids and significant antibacterial activity. The stability of the modified cotton fabrics, even under various treatments, makes them highly desirable for long-lasting anti-fouling, oil/water separation, and antibacterial applications.

Summary: Peony seed cake extract (PSCE) was used to synthesize silver nanoparticles (Ag NPs) with antibacterial, antioxidant, and cytotoxicity properties. The PSCE-Ag NPs showed a spherical shape, average size of 105.6 ± 3.49 nm, and a zeta potential of -41.8 ± 12.6 mV. They effectively inhibited the growth and biofilm formation of various bacteria and exhibited strong free radical scavenging ability. Furthermore, the PSCE-Ag NPs were non-toxic to erythrocytes, egg-chorioallantoic membrane, and human embryonic kidney cells (HEK293), while significantly suppressing breast cancer cell (BT474) growth.

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: Modifying the properties of graphene, such as inducing ferromagnetism, has attracted wide interest. This study investigated the interaction between protons and graphene, the mechanism of ferromagnetism induction, and whether protons remain in graphene. The results show that implanted hydrogen remains chemisorbed in graphene and the interlayer expansion is caused by carbon interstitials rather than remaining hydrogen. The magnetic moment is related to the amount of interstitial carbon, indicating that room-temperature ferromagnetism arises from disrupted carbon bonding.

Summary: In this study, we investigated the surfaces of single crystalline BaMnSb2 and found two different terminations with drastically different morphologies and electronic properties. The reconstructed structures, defect types, and electronic structures of the two terminations were extensively studied. We also observed that the surface termination significantly influenced the surface-projected electronic band structures, and the presence of defects led to electronic phase separations on the surface.

Summary: We investigate the magnetic and electronic transport properties of Mn-doped LaTi1-xMn(x)O3(x=0,0.1,0.3,0.5) as a function of temperature and an applied magnetic field. Magnetic transition is observed in the doped samples but not in the parent LaTiO3. Fluctuations in magnetization at low fields below the Neel transition temperature suggest electronic phase separation in the material. The increase in Mn content strengthens the ferromagnetic-like moment while maintaining the G-type antiferromagnetic phase through charge transfer and influence on orbital ordering.

Summary: This study investigates the influence of hole doping on the magnetic properties of the compositionally complex high-entropy oxide La1-xSrx(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O-3. It is found that aliovalent A-site substitution can manipulate the magnetically active B-site sublattice, leading to stronger ferromagnetic response and changes in magnetic anisotropy. Magnetometry results show complex and nonuniform responses, indicating the presence of locally inhomogeneous magnetic phase competition.
