Photodoping in Wide‐Bandgap Perovskite Solar Cells With MXenes
Advanced Optical Materials, EarlyView.Ultrafast tandem spectroscopy and DFT modeling reveal the separate dynamics and the imbalance of electrons and holes in wide bandgap perovskite solar cells with MXene incorporation. The enhanced photoconversion performances of the devices are traced to photodoping, with selective hole trapping and suppressed recombination of electrons.

A Cell Method Model for Sintered Alloys
Computer Modeling in Engineering & Sciences, 2011 In industrial applications, microstructure inhomogeneities can derive from the manufacturing process and the final mechanical properties of the material depend on the resulting, complex, structural pattern of the constituents. In this paper, Cell Method plane models in the elastic and plastic fields are presented and applied to predict the behaviour of

Advanced Science, EarlyView.This study achieves anisotropic thermal expansion tuning in Nd2(Co1‐xFex)17‐yCry compounds via a magnetoelastic strategy. Variable‐temperature synchrotron X‐ray diffraction reveals that increased Fe content induces switchable lattice responses. Compositional control reduces the volume expansion coefficient αV by 20% (x═0.7) and modulates TC (442–625 K),

Polymorphic Superparaelectric Engineering Boosting Energy Storage Capacity in BaTiO3‐Based Ceramics
Advanced Science, EarlyView.Herein, Ca2+ incorporation promotes the coexistence of CaTiO3‐/BaTiO3‐derived paraferroelectric states, stabilizing cubic‐orthorhombic‐tetragonal polymorphic superparaelectric phases. This minimizes polarization energy barriers, facilitating full polarization saturation without compromising efficiency.
