Abstract Interpenetration in metal–organic frameworks (MOFs) is an intriguing phenomenon with significant impacts on their properties, and functional applications. Herein, we show that a 7‐fold interpenetrated MOF ( 1 ) transformed into 8‐fold by the loss of DMF single‐crystal‐to‐single‐crystal manner. This accompanied giant enhancement second harmonic generation (SHG ca. 125 times) two‐photon photoluminescence (ca. 14 times). The strengthened π–π interaction between individual diamondoid...
To obtain the best comprehensive performance of flux-switching permanent magnet (FSPM) machines, six cogging torque suppression techniques based on rotor-side including skewing, step-skewing, notching, pairing, right-angle chamfering, and cos-chamfering rotors are investigated in this article. First, mechanisms rotor classified into two categories analyzed through general air-gap field modulation theory (AFMT). Then, finite element analysis (FEA), waveforms FSPM machine by each technique...
Abstract Metal halide perovskites (MHPs) are promising materials for a range of optoelectronic applications owing to their unique structures and optical properties. The photoluminescence (PL) property MHPs is crucial applications. All‐inorganic such as CsPbBr 3 , CsPb 2 Br 5 Cs 4 PbBr 6 have been widely investigated due high PL quantum yield (QY). However, the mechanisms these still remain controversial lack unifying explanation. In this review, we summarized recent efforts reveal emission...

Carbon dots (CDs) have emerged as a promising new type of fluorescent nanomaterial, although one their main problems is the tuning emission wavelength toward long region. In this work, influence reaction solvents to CDs was systematically studied using four groups classical precursors (citric acid individually mixed with nitrogenous organic compounds). Water and toluene were selected represent hydrophobic hydrophilic medium, respectively. It interesting observe that in solvent, all CD...
Axial-flux permanent magnet (AFPM) machines are gaining popularity in low-speed and high torque applications due to their density, efficiency, compact structure. In this article, a dual-rotor slotless AFPM (DRSAFPM) machine equipped with equidirectional toroidal winding (EDTW) is proposed compared that conventional single-layer double-layer concentrated windings (CWs). First, the differences between DRSAFPM EDTW CWs coil layout, electromotive force (EMF), magnetomotive revealed. Considering...
