Imbalanced Surface Charge Induced Phase Segregation in Mixed Halide Perovskites
Advanced Functional Materials, EarlyView.The key factor determining the phase segregation in mixed halide perovskites (MHP) is the intrinsic imbalanced surface charges in the crystal lattice. MHP films with excellent crystallinity and surface morphology can suffer severe phase segregation.

Effect of average number of reference speckles on the SNR of object retrieved using off-axis holographic technique [PDF]
arXiv, 2017 The propagation of coherent light through a random scattering medium generates speckle pattern. Although the speckle is random in nature, the object information is scrambled into it. The scrambled object information can be retrieved using off-axis holographic technique where the retrieval is made from coherence hologram which is constructed from the ...

Understanding the Role of Hydrogen and Oxygen in Electronic Phase Changes of Nickelates
Advanced Functional Materials, EarlyView.The reversible exchange of hydrogen and oxygen in solids is key to their electronic and electro‐chemical functionality. A combination of methods is employed to study the interaction of hydrogen with a prototypical quantum material in a non‐destructive and time‐dependent manner.

Advanced Functional Materials, EarlyView.Surface‐attached multilayer micromagnet systems are fabricated by two‐photon crosslinking. The pillar‐shaped micro actuators consist of a soft and flexible surface‐attached cell‐repellent hydrogel layer at the bottom, acting as a hinge and a cell‐adhesive hydrophobic polymer filled with magnetic nanoparticles.
