2023年4月1日 · In this study, the performance of MnNb 2 O 6 /g-C 3 N 4 (MNO/g-CN) composites in the photocatalytic degradation of ciprofloxacin (CIP) and tetracycline-HCl (TCH) antibiotics was explored.

2018年6月25日 · MnNb 2 O 6 has abundant reaction sites for faradic reaction to enhance charge storage. Crystal morphologies of MnNb 2 O 6 show an evolution with the hydrothermal time. MNO-1d possesses ordered six-leaf structure composed by hierarchical nanosheets. MNO-1d delivers 350 F g −1 and retention 315 F g −1 after 10000 cycles at 10 A g −1.

MNN is a highly efficient and lightweight deep learning framework. It supports inference and training of deep learning models and has industry-leading performance for inference and training on-device.

2019年3月11日 · It is found that MnNb 3 S 6 exhibits strong magnetic anisotropy between the c -axis and the ab -plane, but no magnetic anisotropy within the ab -plane. The magnetization with is much stronger than that with H // c, and a field-induced magnetic phase transition is found when .

2022年1月15日 · In this work, ultrathin amorphous carbon shells and lattice defects (heteroatoms and vacancies) are introduced into the MnNb 2 O 6 nanofiber surface to improve the electron/ion kinetic stability, conductivity and electrochemical activity.

2010年5月7日 · Homogeneous manganocolumbite (MnNb 2 O 6) was synthesized from Nb 2 O 5 and MnO oxides. Powder sample was orthorhombic with unit cell parameters: α = 0.5766 nm, b = 1.4439 nm, c = 0.5085 nm and V = 0.4234 nm 3.

Great efforts have been made to synthesize columbite niobates due to their fascinating properties and applications. In this research, ellipsoidal MnNb 2 O 6 crystals have been successfully prepared by a facile hydrothermal method. X-ray powder diffraction patterns showed that the products have the typical orthorhombic columbite structure.

2006年7月6日 · Find more information on the Altmetric Attention Score and how the score is calculated. A manganocolumbite with nominal composition MnNb 2 O 6 has been prepared under air in order to characterize its electrical behavior.

2014年7月28日 · High-pressure Raman scattering and X-ray diffraction studies on manganese niobate (MnNb 2 O 6) have been carried out in a diamond anvil cell at room temperature up to 41 GPa. A pressure-induced phase transition was observed at 12 GPa accompanied by the softening of two internal vibration modes ν 10 (B 2g) and ν 8 (A g).
