Covalent Adaptable Networks with Tailorable Material Properties Based on Divanillin Polyimines. [PDF]

Biomacromolecules
Covalent adaptable networks (CANs) are being developed as future replacements for thermosets as they can retain the high mechanical and chemical robustness inherent to thermosets but also integrate the possibility of reprocessing after material use. Here,

A minimal cellulosome‐like system in Cellulosilyticum lentocellum

FEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

“In Water” Fabricated and Recycled Covalent Adaptable Acylhydrazone Thermosets

Macromolecular Materials and Engineering, 2023
Thermosetting resins play an increasingly important role in daily life due to their good mechanical properties. However, they can hardly be recycled and reused, leading to severe environmental pollution.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

Aging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

Advanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

Unraveling the rheology of inverse vulcanized polymers

Nature Communications, 2023
Multiple relaxation times are used to capture the numerous stress relaxation modes found in bulk polymer melts. Herein, inverse vulcanization is used to synthesize high sulfur content (≥50 wt%) polymers that only need a single relaxation time to describe

Dissociative covalent adaptable networks from unsaturated polyesters [PDF]

Unsaturated polyesters (UPEs) are a class of thermosetting resins which are prevalent in the polymer industry, offering excellent durability in many applications. However, their permanent crosslinks prevent re-use or recycling at their end-of-life.
