Abstract Nanoporous solids, including microporous, mesoporous and hierarchically structured porous materials, are of scientific technological interest because their high surface-to-volume ratio ability to impose shape- size-selectivity on molecules diffusing through them. Enormous efforts have been put in the mechanistic understanding diffusion–reaction relationships nanoporous with ultimate goal developing materials improved catalytic performance. Single-molecule localization microscopy can...

We investigate the collective behavior of suspended thermoresponsive microgels, that expel solvent and subsequently decrease in size upon heating. Using a binary mixture differently we demonstrate how distinctly different gel structures form, depending on heating profile used. Confocal laser scanning microscopy (CLSM) imaging shows slow ramps yield core-shell network through sequential gelation, while fast random homo-gelation. Here, secondary particles are shown to aggregate monolayer...

Dual-fluorescence carbon dots have great potential as nanosensors in life and materials sciences. Such can be obtained via a solvothermal synthesis route with glutathione formamide. In this work, we show that the dual-fluorescence emission of products does not originate from single dot emitter, but rather mixture physically separate compounds. We characterized UV-vis, Raman, infrared, fluorescence spectroscopy, identified blue-emissive red-emissive porphyrin. demonstrate an easy way to two...

Nanocrystals (NCs) doped with lanthanides are capable of efficient photon upconversion, i.e., absorbing long-wavelength light and emitting shorter-wavelength light. The internal processes that enable upconversion a complex network electronic transitions within energy transfer between dopant centers. In this work, we study the rise decay dynamics emission from β-NaYF

Abstract Single-particle tracking is a powerful approach to study the motion of individual molecules and particles. It can uncover heterogeneities that are invisible ensemble techniques, which places it uniquely among techniques mass transport. Analysis trajectories obtained with single-particle in inorganic porous hosts often challenging, because short and/or heterogeneous. We present DiffusionLab software package for analysis such challenging data sets. Trajectories first classified into...

We have used confocal laser scanning microscopy on the small, fluorescent resorufin dye molecule to visualize molecular accessibility and diffusion in hierarchical, anisotropic pore structure of large (~10 μm-sized) zeolite-β crystals. The is widely life materials science, but only its deprotonated form because protonated barely aqueous solution. In this work, we show that fact strongly when confined within zeolite micropores, thus enabling fluorescence microimaging experiments. find...

In this article, we demonstrate a method for inducing reversible crystal-to-crystal transitions in binary mixtures of soft colloidal particles. Through controlled decrease salinity and increasingly dominating electrostatic interactions, single sample is shown to reversibly organize into entropic crystals, attraction-dominated or aggregated gels, which quantify using microscopy image analysis. We furthermore analyze crystalline structures with bond order analysis discern between two crystal...

The work reported here is the first study aimed at providing a full screening of real unsortable non-recycled post-consumer WEEE stream free brominated flame retarded plastics, separated using on-line X-ray detection, toward its recycling. In existing sorting lines, up to 40% plastics from waste electrical and electronic equipment (WEEE) can be rejected, herein named plastics. To have most representative homogeneous sample for physico-chemical characterizations, sampling method was developed...

Simple models based on isotropic interparticle attractions often fail to capture experimentally observed structures of colloidal gels formed through spinodal decomposition and subsequent arrest: the resulting are typically denser less branched than their experimental counterparts. Here, we simulate from soft particles with directional ("patchy particles"), designed inhibit lateral particle rearrangement after aggregation. We directly compare simulated made using attractive microgel...

Microscopy and particle-based simulations are both powerful techniques to study aggregated particulate matter such as colloidal gels. The data provided by these often contains information on a wide array of length scales, but structural analysis methods typically focus the local particle arrangement, even though also about network mesoscopic scale. In this paper, we present MATLAB software package for quantifying structures in samples. ArGSLab (Arrested Gelated Structures Laboratory)...

Micro- and nanoscale information on the activating deactivating coking behaviour of zeolite catalyst materials increases our current understanding many industrially applied processes, such as methanol-to-hydrocarbon (MTH) reaction. Atom probe tomography (APT) was used to reveal link between framework coke elemental distributions in 3D with sub-nanometre resolution. APT revealed 10-20 nanometre-sized Al-rich regions short-range ordering (within nanometres) Al atoms. With confocal fluorescence...
