We prepared a hybrid hydrogel system by doping the gold nanorods (GNRs) into the thermal responsive hydrogel. The near-infrared (NIR) laser was used to trigger the release of loaded Doxorubicin (DOX) by utilizing the photothermal effect of GNRs to induce the contraction of thermo-responsive hydrogels. The development of the hydrogel as the carrier is for the chemo-photothermal co-therapy of local breast cancer recurrence. The DOX-PCNA-GNRs hydrogel effectively prevented breast cancer recurrence after primary tumor resection in a mouse model.
Development of methylammonium lead halide perovskites for efficient solar cell is best approach towards efficient building photovoltaic. This article demonstrates the synthetic strategy for the synthesis of efficient and stable CH3NH3PbBr3 quantum dots for efficient mesoscopic solid-state perovskite solar cells. The influence of different CH3NH3PbBr3 quantum dot size and different hole-transporting materials has been discussed systematically.
We report the catalyst-free growth of InAs/InxGa1−xAs coaxial nanorod heterostructures on large-area graphene layers using molecular beam epitaxy and our investigation of the chemical composition and crystal structure of these heterostructures using electron microscopy. Cross-sectional electron microscopy images showed that InxGa1−xAs layers, having uniform composition, coated heteroepitaxially the entire surface of the InAs nanorods, without interfacial layers or structural defects. The catalyst-free growth mechanism of InAs nanorods on graphene was investigated using in situ reflection high-energy electron diffraction.
We at the first time demonstrate that the Ni/Mn disordering in LNMO spinel is decoupled from the presence of Mn3+ ions by doping Li and strongly affects phase transformation resulting in the increase of solid-solution phase transformation. The resulting material with 1–2 μm achieves superior rate capability, 120 mAh g−1 at ~38 C and 60 mAh g−1 at 60 C.
A large number of multilayered stacking faults are detected along {111} planes during aging (arrows in a) of present superalloy. Every γ′ phase particle is isolated by multilayered stacking-fault ribbons and grows slightly. The coarsening rate of the γ′ phase decreases significantly after plastic deformation, implying that the formation of multilayered stacking-fault ribbons as a consequence of Suzuki segregation can obviously retard the coarsening of γ′ phase in this novel alloy.
Formation of nanoparticles have shown significant improvement in quality of size, shape and dispersity based on recent advanced biosynthesis approaches by understanding the natural mechanisms underlying nanoparticles synthesis. Considering the biocompatibility, cost effectiveness and eco-friendliness, bio-associated synthesis of nanoparticles may provide the promising solutions to the challenge faced in the applications of industry and biomedicine.
