3D MoS2–Graphene Microspheres Consisting of Multiple Nanospheres with Superior Sodium Ion Storage
Seung Ho Choi, You Na Ko, Jung-Kul Lee and Yun Chan Kang
3D MoS2–graphene composite microspheres consisting of multiple nanospheres are prepared by a one-pot spray pyrolysis process with high scale-up potential. The 3D MoS2–graphene composite microspheres show high reversible capacity and long cycle stability as anode materials for sodium-ion batteries. The facile and continuous synthesis of 3D graphene-based composite microspheres could be applied to the potential materials for various fields including energy storage.
Morphological Control for High Performance, Solution-Processed Planar Heterojunction Perovskite Solar Cells

The critical role of perovskite morphology in planar heterojunction perovskite solar cells is probed and understood. Dewetting of online casino perovskite films is minimized, to achieve uniform 100% coverage perovskite layers. Solution cast planar heterojunction solar cells with efficiencies of up to 11.4% are fabricated, a new record for such cells with no mesoporous layer.
TPA Immobilization on Iron Oxide Nanocubes and Localized Magnetic Hyperthermia Accelerate Blood Clot Lysis
Eszter Voros, Minjung Cho, Maricela Ramirez, Anna Lisa Palange, Enrica De Rosa, Jaehong Key, Zsolt Garami, Alan B. Lumsden and Paolo Decuzzi
Clustered super-paramagnetic 20 nm iron oxide nanocubes, stabilized by tissue plasminogen activator molecules and serum albumin, are proposed as thrombolytic agents. In vitro, as compared to tissue plasminogen activator, these nanoconstructs demonstrate a ≈1000-fold increase in dissolution rate. Intravital microscopy experiments demonstrate blood vessel reperfusion within a few minutes post tail vein injection of tissue plasminogen activator nanocubes.
