In the dry or frozen states, macromolecules are damaged directly by interactions with ionizing radiation. Since γ-rays and high-energy electrons randomly ionize orbital electrons in their path, larger molecules are more likely to suffer an...

Surface wrinkles are interesting since they form spontaneously into well-defined patterns. The mechanism of formation is well-studied and is associated with the development of a critical compressive stress that induces the elastic instabili...

We investigate the effects of salt concentration and pH on neutralized poly(acrylic acid) (PAA) gels in near physiological salt solutions. Either adding calcium ions or decreasing the pH are found to induce reversible volume transitions but...
