Comparison between fluorometry and microscopy‐based phytoplankton assessments in the Laurentian Great Lakes

Limnology and Oceanography: Methods, EarlyView.
Abstract Photosynthetic pigment fluorescence is commonly used in limnology and oceanography as a proxy for phytoplankton biomass. Fluorometry has been used to detect subsurface algal blooms, characterize dynamics of the deep chlorophyll layer, and to provide greater vertical resolution to phytoplankton monitoring.

Study on the Shape Memory Performance of 4D‐Printed Auxetic Cellular Structures with Energy Absorption Application

Macromolecular Materials and Engineering, EarlyView.
4D‐printed auxetic cellular structures made from PETG demonstrate almost complete recovery of shape and mechanical properties after repeated loading. Two strategies successfully addressed the low shape‐fixity issue, the primary limitation of cold programming.

Impact of E‐Beam Sterilization on Bioglass Composite Shape Memory Scaffolds

Macromolecular Materials and Engineering, EarlyView.
Electron beam (E‐beam) sterilization is an attractive alternative to conventional methods (e.g., ethylene oxide) to sterilize medical devices such as scaffolds used to heal bone defects. Herein, the impact of E‐beam sterilization on the properties of “self‐fitting” shape memory polymer (SMP) scaffolds prepared from resorbable polyesters and a bioglass ...

Stimuli‐Responsive 3D‐Printed Structurally Colored Materials Based on Core–Shell Particle Architectures

Macromolecular Materials and Engineering, EarlyView.
A novel, structurally colored and pH‐responsive filament for FDM 3D‐printing is presented, which is based on tailored core–shell particles with methacrylic acid as a comonomer in the particle shell. The pH‐responsiveness of the printed objects is achieved due to particle swelling in alkaline conditions.

Advancements in 3D Printing of Self‐Healing Polymer Systems

Macromolecular Materials and Engineering, EarlyView.
This review provides an overview of the most common 3D printing technologies and summarizes the numerous methods to produce self‐healing materials. The challenges and strategies used to adapt these methods to 3D printing are then highlighted to provide a framework for future research in 3D printing self‐healing polymer systems.
