The first-line treatment for advanced hepatocellular carcinoma (HCC) combines immune checkpoint inhibitors and antiangiogenesis agents to prolong patient survival. Nonetheless, this approach has several limitations, including stringent inclusion criteria suboptimal response rates that stem from the severe off-tumor side effects unfavorable pharmacodynamics pharmacokinetics of different drugs delivered systemically. Herein, we propose a single-agent smart nanomedicine-based mimics therapeutic...
We reported the resistance switching (RS) behavior in epitaxially grown CeO2/ La0.7(Sr0.1Ca0.9)0.3MnO3 (CeO2/LSCMO) heterojunctions on SrTiO3 substrate. The CeO2/LSCMO device displayed improved characteristics as compared to that of metal/manganite device. threshold voltage showed a strong dependence thickness CeO2 layer, where minimum/maximum was required for appearance switching. Both set and reset voltages increase with layer due trap-assisted electron tunneling effect. In meantime,...
The magnetic and transport properties of La0.7Sr0.3Mn1−xCoxO3 (0 ≤ x 1) samples were systematically studied. A phase diagram was constructed according to the observed results. At two ends (x 0.3 > 0.9), exhibit conventional ferromagnetism with metallic conducting behavior, which can be interpreted in terms double exchange coupling between Mn (Co) ions. As for intermediate Co-doping region (0.3 < enter a mixed state, displays characteristics glassy states. According...
Abstract Liver cancer is a common malignant tumor worldwide, traditional Chinese medicine one of the treatment measures for liver because its good anti-tumor effects and fewer toxic side effects. Ginsenoside CK (CK) an active component ginseng. This study explored mechanism by which induced ferroptosis in cells. We found that inhibited proliferation HepG2 SK-Hep-1 cells, Ferrostatin-1, inhibitor, was used to verify role inducing Network pharmacological analysis identified FOXO pathway as...
A special kind of asymmetric magnetization reversal characterized by a sharp step in the second quadrant hysteresis loop has been investigated exchange biased Co/CoO films. This asymmetry only exists film where small clusters grow to form islands. bimodal distribution first-order curves diagram demonstrates that irreversible is composed free part and part, originating from grains smaller larger than 6 nm film, respectively. The finite-size effect antiferromagnetic anisotropy ultrafine...
The exchange bias effects in pulsed laser deposited CoO1−δ/(NiFe,Fe) bilayers were investigated. An anomalously high blocking temperature (TB) of 325 K was obtained for the as-deposited CoO1−δ/ferromagnet bilayers, which is 33 higher than Néel bulk CoO (TN = 292 K). amount oxygen vacancies δ CoO1−δ film can be controlled by a post-annealing treatment O2 atmosphere. TB increases with an increasing from 0 to 0.16. Our results indicate that originates enhancement magnetic interaction layer...
The exchange bias effect and training of the Co/CoO film with induced uniaxial anisotropy were investigated as functions temperature. It was found that both effects exhibited drastic differences along easy hard axes. Along axis, magnetization reversal dominated by domain wall motion throughout whole temperature range. However, rotation at temperatures below above 150 K, respectively. crossover two modes characterized significant asymmetry in hysteresis loop observed axis K due to interplay...
A high efficiency near-infrared (NIR) photomultiplication-type organic photodetector (PM-OPD) has been achieved by combining the energetic disorder and trap-assisted charge tunneling injection. The performance of prepared NIR PM-OPD with simple structure was significantly improved, external quantum specific detectivity (D*) reached 5675% 5.0 × 1011 Jones, respectively. Furthermore, high-performance also showed application in human heart rate detection.
The bipolar resistance switching behavior was observed in the epitaxially grown CeO2/La0.7(Sr0.1Ca0.9)0.3MnO3 (CeO2/LSCMO) heterojunctions on SrTiO3 substrate using pulsed laser deposition technology. It found that magnetization of CeO2/LSCMO heterojunction varies with state device when external triggered voltage is higher than set and reset voltages. could be reversibly changed by exerting voltages junction. electron tunneling accompanied a trapping/detrapping process at interface likely...
It was found that by using the same α-Fe2O3 target in fabrication process, an oxygen-deficient and oxygen-sufficient atmosphere facilitated formation of Fe3O4 α-Fe2O3, respectively. The Au/α-Fe2O3/Pt heterostructure showed a memristive bipolar resistance switching. A clear difference observed transport magnetic properties between two states. enhanced conductivity magnetization are believed to result from electron hopping Fe3+-Fe2+ pairs Fe3+-O-Fe2+ double exchange coupling effect.
