Photopolymerization‐Induced Phase Separation in (Meth)Acrylate‐Based Photopolymers From a Characterization Point of View

open access: yesJournal of Applied Polymer Science, Volume 142, Issue 36, September 20, 2025.
ABSTRACT This work investigates the development of photopolymerization‐induced phase separation (PhIPS) in methacrylate‐based photopolymers. Bisphenol A ethoxylated dimethacrylate (BisEMA) was copolymerized with urethane‐based diacrylate diluted in isobornyl acrylate (UI) under UV irradiation, using diphenyl‐(2,4,6‐trimethylbenzoyl) phosphine oxide ...

Recycling of PE/PA/EVOH Multilayer Flexible Packaging Films via Reactive Compatibilization

open access: yesJournal of Applied Polymer Science, Volume 142, Issue 33, September 5, 2025.
ABSTRACT The recycling of a 7‐layer co‐extruded blown flexible film composed of polyethylene (LLDPE/LDPE blend), polyamide‐6/6.6 (PA), and random copolymer of ethylene vinyl alcohol (EVOH) was assessed via reactive compatibilization using a maleic anhydride grafted polyethylene.

Precursor Inhomogeneities Influence the Properties of Multimetal Oxides as Shown for LiNi0.5Mn1.5O4 Derived from Hydrothermally Synthesized Precursors

open access: yesAdvanced Science, Volume 12, Issue 36, September 25, 2025.
Correlative Raman and scanning electron microscopies are used for identifying compositional differences on the micrometer length scale in LiNi0.5Mn1.5O4 cathode materials, and it is shown that these compositional differences can be linked to the electrochemical signature of the material. Abstract Co‐precipitation is an attractive means for synthesizing

GGR Handbook of Rock and Mineral Analysis Chapter 16 Nano‐Imaging for Advanced X‐Ray Fluorescence and Absorption Spectroscopy Applications

open access: yesGeostandards and Geoanalytical Research, Volume 49, Issue 3, Page 495-533, September 2025.
Key Points Synchrotron nano‐imaging is necessary to locate elemental nanophases. Trace metal quantification requires high sensitivity nano‐XRF. Trace metal speciation relies on nano‐XANES using nano‐XRF. This chapter (Nano‐Imaging for Advanced X‐ray Fluorescence and Absorption Spectroscopy Applications) is a contribution to the Geostandards and ...

Modified embedding procedure for microtomy of large particle zeolites

open access: yesJournal of Electron Microscopy Technique, 1990
AbstractA method is described to strengthen the binding of organic resin to inorganic zeolite, allowing large particles to be microtomed. For FeZSM‐5 aggregates the particle size limit increased from 3 μm to greater than 20 μm in diameter by application of this method.
