Biodegradable polymers are increasingly at the heart of therapeutic devices. Particularly in the form of thin and elongated fibers, they offer an effective strategy for controlled-release in a variety of biomedical configurations such as sutures, scaffolds ...
We propose and investigate a minimal mechanism that makes use of differential swelling to modify the critical buckling conditions of elastic bilayer shells, as measured by the knockdown factor. Our shells contain an engineered defect at the north pole and ...
Natural polymers such as those present in foods contain abundant noncovalent intra- and intermolecular interactions, notably hydrogen bonds, which make them rigid when dry, but on exposure to water soften, due to disruption of these interactions. This soft ...

Circumventing inherent embrittlement, poor heat resistance, and melt elasticity of poly(lactic acid) (PLA) without compromising its remarkable stiffness and strength has become a particular challenge in polymer science due to increasing demand for green ma ...
Organic semiconductors are important components for applications in different fields of technology, as their advantages include the possibility of low-temperature processing as well as low-cost, large-area manufacturing based on solution-based processes, c ...
Bioresorbable implantable medical devices show great potential for applications requiring medical care over well-defined periods of time. Such implants naturally degrade and resorb in the body, which eliminates adverse long-term effects or the need for a s ...
In the present work, we studied the NH(3)and H2S odor fluxes between the exposed working area and the HDPE covering film holes of the daily overlay in an actual landfill site with a daily operating area of 1600 m(2)in Hangzhou, China. We showed that the od ...

Chemically cross-linked polydimethylsiloxane (PDMS) elastomers have gained importance as a dielectric in elastic capacitor actuators, which elongate when electrically charged. Common PDMS elastomers have a dielectric permittivity of only about 3 and thus e ...
