Strain-stabilized perovskites The perovskite materials used for solar cells and light-emitting diodes (which are black in color) generally less stable at room temperature than the electronically inactive nonperovskite phases yellow color). Steele et al. show that CsPbI 3 , strain induced a thin film after annealing material to 330°C then rapidly cooling it kinetically trapped phase. Grazing-incidence wide-angle x-ray scattering revealed crystal distortions texture formation created by...
Organometal halide perovskites show promising features for cost-effective application in photovoltaics. The material instability remains a major obstacle to broad because of the poorly understood degradation pathways. Here, we apply simultaneous luminescence and electron microscopy on first time, allowing us monitor situ morphology evolution optical properties upon perovskite degradation. Interestingly, morphology, photoluminescence (PL), cathodoluminescence samples evolve differently driven...
The impressive optoelectronic performance and low production cost of metal halide perovskites have inspired applications well beyond efficient solar cells. Herein, we widen the materials engineering options available for selective photocatalytic oxidation benzylic alcohols, an industrially significant reaction, using formamidinium lead bromide (FAPbBr3) other perovskite-based materials. best was obtained a FAPbBr3/TiO2 hybrid photocatalyst under simulated illumination.

The direct conversion of C3 sugars (or trioses) to alkyl lactates was achieved using zeolite catalysts. This reaction represents a key step towards the efficient bio-glycerol or formaldehyde added-value chemicals such as lactate derivatives. highest yields and selectivities desired product were obtained with Ultrastable Y materials having low Si/Al ratio high content extra-framework aluminium. Correlating types amounts acid sites present in different zeolites reveals that two functions are...
Abstract Plasma coating technologies have been demonstrated as being promising for the fabrication of bioactive and biocompatible materials, among others. Reported efforts are exclusively focused on two‐step approaches, in which component is first immobilized a substrate, followed by (vacuum) plasma polymerization treatment or vice versa. However, we believe that upon minimizing energy, numerous substances such enzymes nucleic acids can be directly plasmas via copolymerization with organic...
We report a rationale for identifying superior dyes stimulated-emission depletion (STED) microscopy. compared the pPDI and pTDI, which displayed excellent photostability in single-molecule spectroscopy. Surprisingly, their performance STED microscopy differed significantly. While single pTDI molecules could be visualized with resolution (35 nm), bleached rapidly under similar conditions. Femtosecond transient absorption measurements proved that overlap between band excited-state is main...
We have selected aptamers binding to lysozyme from a DNA library using capillary electrophoresis-systematic evolution of ligands by exponential enrichment. During the selection process dissociation constant ssDNA pool decreased micromolar low nanomolar range within five rounds selection. The final aptamer had 2.8 ± 0.3 nM, 6.1 0.5 and 52.9 9.1 nM as determined fluorescence anisotropy, surface plasmon resonance affinity electrophoresis respectively. were successfully challenged for...
Photoluminescence (PL) of organometal halide perovskite materials reflects the charge dynamics inside material and thus contains important information for understanding electro-optical properties material. Interpretation PL blinking methylammonium lead iodide (MAPbI3) nanostructures observed on polycrystalline samples remains puzzling owing to their intrinsic disordered nature. Here, we report a novel method synthesis high-quality single-crystal MAPbI3 nanorods demonstrate study blinking. At...
The development of novel molecular sieves opens opportunities in the more sensitive analytical devices.

In this paper a fiber optic surface plasmon resonance (FO-SPR) sensor was used to analyze the melting process of DNA linked silica nanoparticles. Real-time monitoring has rarely been studied using (SPR), since most commercial SPR setups do not allow for dynamic and accurate temperature control above 50 °C. The FO-SPR platform, with nanobead signal amplification, allows sensing inside standard PCR thermocycler, which makes high resolution curve analysis possible. This innovative combination...
Photocatalytic reactions occur at the crystal-solution interface, and hence specific crystal facet expression surface defects can play an important role. Here we investigate structure-related photoreduction zinc oxide (ZnO) microparticles via integrated light electron microscopy in combination with silver metal photodeposition. This enables a direct visualization of activity crystallographic features. It is found that nanoparticle photodeposition on dumbbell-shaped crystals mainly takes...
Abstract Spatial restrictions around catalytic sites, provided by molecular‐sized micropores, are beneficial to reaction selectivity but also inherently limit diffusion. The molecular transport can be enhanced introducing meso‐ and macropores. However, the impact of this extraframework porosity on local nanoscale reactivity is relatively unexplored. Herein we show that area in hierarchical zeolite, examined with super‐resolution fluorescence microscopy, spatially restricted narrow zones...
