TiO₂/Al₂O₃/Fe₃O₄的低温水热法制备及其光催化和磁回收性能

Gongye shui chuli, 2015
以原位合成法制备的Al2O3/Fe3O4磁性粒子为载体, 采用低温水解法制备了TiO2/Al2O3/Fe3O4磁载光催化剂。用XRD、SEM、TEM等对制备的磁载光催化剂的结构进行了表征。以25 mg/L苯酚为模拟污染物, 对制备的磁载光催化剂的催化性能进行了考察。结果表明:对于n(TiO2):n(Al2O3):n(Fe3O4)= 60:5:1条件下制备的磁载光催化剂, 当光催化反应时间为120 min, 催化剂质量浓度(以TiO2计)为1 g/L时, 降解苯酚的反应速率常数为0.022 3 ...

Efficient Spin‐Orbit Torques Enabled by Vanadium‐Induced Orbital Currents for Neuromorphic Computing

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Spin‐orbit torque (SOT) provides an efficient electrical pathway for encoding spin states and underpins emerging, ultrafast, and nonvolatile spintronic memories and logic devices. Reducing the switching current density and power consumption remains a central challenge for practical applications.

Structure–Property Relationship‐Guided Mechanisms for Electromagnetic Wave Absorption, Triboelectric Generation, and Negative Permittivity in Magnetic Metacomposites

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT The composition and structural characteristics of metacomposites are crucial for tuning their negative electromagnetic parameters; however, the lack of a clear structure–property relationship severely limits their application in dielectric and magnetic fields.

Exceptional Multifunctional Performance Enabled by a Network Architecture in Additively Manufactured NiFe‐Based Soft Magnetic Alloys

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT The mechanical properties and corrosion resistance of traditionally as‐cast soft magnetic Ni‐50Fe alloys often fail to meet current application requirements. To address this limitation, this study employed direct energy deposition (DED) to fabricate two kinds of soft magnetic alloys: Ni‐50Fe and Ni‐48.5Fe‐1.5Cu‐1.5Ti.

Super‐High Coercivity Sintered NdFeB Magnets Enabled by High‐Rate Dy/Tb Grain Boundary Synergistic Diffusion

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT The surging demand for high‐performance NdFeB magnets has made it essential to achieve ultrahigh coercivity while minimizing the consumption of heavy rare earths. To tackle this challenge, this study proposes a Dy/Tb bilayer grain boundary diffusion strategy and systematically investigates the co‐diffusion behavior of Dy and Tb.

La3+ Vacancy Mediated Enhancement of Near‐Infrared Emission in Cr3+‐Activated La2MgTiO6 Phosphors for Multifunctional Applications

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Near‐infrared (NIR) phosphors with broadband and efficient emission are pivotal for the performance of NIR phosphor‐converted light emitting diodes (pc‐LEDs). In this study, the double perovskite phosphor La2MgTiO6:Cr3+ phosphor with broadband emission in the range of 650–950 nm was prepared.

Kinetic‐Controlled Growth of Iron Chalcogenide Nanosheets Featuring Besnus Transition

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Two‐dimensional (2D) Fe‐based nanosheets have sparked wide attention owing to exotic magnetism, superconductivity and topological phases. However, the synthesis of 2D FemXn (X = Te/Se/S, m, n: integer), typically in a non‐stoichiometric ratio, remains challenging because of narrow thermodynamic windows.

基于等效磁荷法的地磁观测仓体磁场分布

Dizhen xuebao
利用等效磁荷方法计算了非轴向磁化圆柱形有底仓体表面的磁荷密度分布和仓内的磁场分布，并与计算机仿真和实测结果进行了对比，结果显示其相对差值＜0.001%。在此基础上，利用该方法计算了无底仓体及不同底部厚度、高度、直径、磁化率的仓体的内部磁场梯度分布情况。结果表明：仓体底部厚度和磁化率对仓体内部磁场梯度的影响较小，增大仓体高度和直径可有效地增加内部的低磁场梯度空间，当仓体内高≥4 m、仓体内径≥1.0 m时，仓体内部水平方向和垂直方向的有效空间占比平均在85%以上。
