Advanced Functional Materials, Volume 35, Issue 52, December 23, 2025.Block copolymer microcapsules with ultrathin, perpendicularly perforated membranes are developed through double emulsions, initiated by the diffusion of water into single emulsions. Both shell thickness and channel diameter can be systematically tuned, offering precision in molecular sieving and significantly enhanced permeation rates.

Dual‐Fluorophore Labeling for Polymer Blending Differentiation and Visualization
Aggregate, Volume 6, Issue 12, December 2025.This work employs a dual fluorescent labeling strategy to visualize phase separation in polymer blends. Using confocal laser scanning microscopy, distinct phase separation is clearly observed in the absence of a compatibilizer. This phenomenon disappears upon compatibilizer addition, demonstrating the strategy's effectiveness in monitoring blend ...

Impact of tissue sample preparation methods on myelin‐sensitive quantitative MR imaging
Magnetic Resonance in Medicine, Volume 94, Issue 5, Page 2071-2085, November 2025.Abstract Purpose Validation of quantitative MRI (qMRI) parameters with histology is often done with ex vivo fixed tissue samples. Freezing is another common form of tissue preservation, but the effects of freezing and thawing tissue on myelin‐sensitive quantitative MRI parameters and their correlation with histology require further analysis.

The Canadian Journal of Chemical Engineering, Volume 103, Issue 10, Page 4774-4785, October 2025.Synthesis of core‐shell calcium hydroxide‐calcium carbonate biocidal particles via encapsulation into dry ice. Abstract This study introduces a novel synthesis method for core‐shell calcium hydroxide‐calcium carbonate (CSCC) biocidal particles by inducing a phase change in liquid CO2, thereby coating CaOH2 in dry ice.

Modified embedding procedure for microtomy of large particle zeolites
Journal 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.

Low Speed Microtomy for the Electron Microscope
Experimental Biology and Medicine, 1949 The beam of a 50-kv electron microscope does not penetrate specimens that are thicker than 0.1 μ. Thus, in order to study biological specimens with this type of microscope we have further developed the technic described by Pease and Baker,1 who altered a Spencer Rotary Microtome (model 820) by adding a wedge to the mechanism for forward movement.
