Due to many potential promising applications, vibration-based piezoelectric energy harvesters (VPEH) with a clamped circular diaphragm are an intensively studied design in the field of piezoelectric energy harvesters. Nonetheless, their performance still leaves space for improvement, which is the primary target of this article.

(Nd,Dy)-Fe-B core shell model magnets were prepared by co-sintering Nd-Fe-B and (Nd,Dy)-Fe-B powders. The Nd-Fe-B core and partially Dy substituted i.e. (Nd,Dy)-Fe-B shell were identified by SEM. MFM measurements of the remanent state revealed a magnetic contrast of core and shell within the same grain.

We congratulate our colleague Ying Zhao to the successful dissertation of her PhD thesis “Phase-field Modeling of Electro-chemo-mechanical Behavior of Li-ion Battery Electrodes”

We present a systematic study on the relation of the electrocaloric effect (ECE) and the relaxor state transition of BaZrxTi1−xO3 (BZT) using a combination of computer simulation and experiment. The results of canonical and microcanonical lattice-based Monte Carlo simulations with a Ginzburg-Landau-type Hamiltonian are compared with measurements of BaZrxTi1−xO3 (x = 0.12 and 0.2) samples.

Improving the rate capability and cycle stability of two-dimensional molybdenum disulfide (MoS2) still holds the key to its application in lithium-ion batteries (LIBs). Here we reported liquid-exfoliated MoS2 nanosheets/graphene composites (MoS2/Gra) towards the high capacity and excellent cycle stability for LIBs.
