Polymer behavior as a research area examines how polymeric materials respond to external and internal stimuli across multiple length and time scales, integrating polymer physics, chemistry, and materials science. It encompasses the study of chain conformation, segmental dynamics, entanglements, and relaxation processes, as well as phase behavior, crystallization, glass transition, and viscoelasticity in melts, solutions, gels, and solid states. Researchers investigate how molecular architecture (e.g., linear, branched, crosslinked, block copolymers), interactions, and processing conditions govern mechanical, rheological, thermal, and transport properties, using theoretical models, simulations, and experiments to predict and tailor macroscopic performance from molecular-level structure and dynamics.
Researchers from Tokyo Metropolitan University have created a new molecule which carries DNA into biological cells, to treat or vaccinate against illnesses. Many existing options rely on molecules with a strong positive charge, ...

Imagine a material cracking—now imagine what happens if there are small inclusions in the material. Do they create an obstacle course for the crack to navigate, slowing it down? Or do they act as weak points, helping the ...

If you've ever watched a glass blower at work, you've seen a material behaving in a very special way. As it cools, the viscosity of molten glass increases steadily but gradually, allowing it to be shaped without a mold. Physicists ...
Polymer micelles are tiny, self-assembled particles that are revolutionizing the landscape of drug delivery and nanomedicine. They form when polymer chains containing both hydrophilic and hydrophobic segments organize into ...

Pictures of DNA often look very tidy—the strands of the double helix neatly wind around each other, making it seem like studying genetics should be relatively straightforward. In truth, these strands aren't often so perfectly ...
