BiFeO 3 , GdFeO 3 and GdFeO 3 /graphene nanofibers were successfully fabricated by using an electrospinning technique with a simple single needle. Their structure, size and morphology were investigated by x-ray diffraction, scanning electron microscopy, transmission electron microscopy, energy-dispersive spectroscopy, and selected area electron diffraction. The diameters of the BiFeO 3 and GdFeO 3 are 60–70 and 80–170 nm, respectively. The electrochemical properties of the BiFeO 3 , GdFeO 3 , and GdFeO 3 /graphene nanofibers for lithium-ion battery applications were evaluated. The results indicate that the GdFeO 3 /graphene composite shows better electrochemical performance than BiFeO 3 and GdFeO 3 nanofibers.

A series of Bi-doped gadolinium iron garnet (Bi:GdIG) infrared-transparent ceramics were fabricated by a hot-press sintering process. The effects of Bi doping on the phase structure, microstructure and optical transmittance of GdIG ceramics were analyzed systematically. The grain size of Bi x Gd 3- x Fe 5 O 12 ( x = 0, 0.3, 0.6, 0.9) ceramic samples gradually decreased with the increase of Bi doping, and their optical transmittance gradually decreased, reaching about 70.7%, 62.9%, 56.9%, and 29.8% at 1550 nm, respectively. Meanwhile, the effects of Bi doping on the magnetic and magneto-optical properties of GdIG ceramics were investigated systematically. The saturation specific Faraday rotation angles ( θ F ) of the Bi x Gd 3- x Fe 5 O 12 ceramic samples reached about 51, −266, −595, and −968 deg./cm, respectively, which increased linearly with the increase of the Bi doping amount. The θ F increased by about 34 deg./cm for each 1 at% increase in the Bi doping amount, achieving comparable magneto-optical properties with Bi:GdIG single crystals produced by liquid phase epitaxy. It shows the bright prospects of Bi:GdIG ceramic materials in the field of magneto-optical applications.

A series of GdIG ceramics with good infrared transparency have been fabricated by a hot-press sintering process with vacuum/oxygen atmosphere. The effects of the powder synthesizing temperature and the ceramic sintering temperature on the phase structure and microstructure of the GdIG ceramics were examined and analyzed. The GdIG ceramic sample sintered at 1275 °C from the Gd 2 O 3 and Fe 2 O 3 powders pre-synthesized at 1000 °C demonstrated an exceptionally high infrared transmittance, it is ≥ 68% within the wavelength range of 1500–5000 nm (t = 0.5 mm). Furthermore, the magnetic and magneto-optic property of the GdIG ceramic samples were investigated and discussed. When a saturation external magnetic field of ∼50 mT acting on the GdIG ceramic sample, the specific Faraday rotation angles are about 104 deg./cm and 51 deg./cm at 1064 and 1550 nm wavelength respectively. It exhibits a good faraday effect of GdIG ceramics which is rarely reported until now.

The development of novel theranostic agents with outstanding diagnostic and therapeutic performances is still strongly desired in the treatment of hepatocellular carcinoma (HCC). Here, a fucoidan-modified mesoporous polydopamine nanoparticle dual-loaded with gadolinium iron and doxorubicin (FMPDA/Gd 3+ /DOX) was prepared as an effective theranostic agent for magnetic resonance imaging (MRI)-guided chemo-photothermal therapy of HCC. It was found that FMPDA/Gd 3+ /DOX had a high photothermal conversion efficiency of 33.4% and excellent T 1 −MRI performance with a longitudinal relaxivity (r 1 ) value of 14.966 mM −1 · s − 1 . Moreover, the results suggested that FMPDA/Gd 3+ /DOX could effectively accumulate into the tumor foci by dual-targeting the tumor-infiltrated platelets and HCC cells, which resulted from the specific interaction between fucoidan and overexpressed p-selectin receptors. The excellent tumor-homing ability and MRI-guided chemo-photothermal therapy therefore endowed FMPDA/Gd 3+ /DOX with a strongest ability to inhibit tumor growth than the respective single treatment modality. Overall, our study demonstrated that FMPDA/Gd 3+ /DOX could be applied as a potential nanoplatform for safe and effective cancer theranostics
