When a negatively charged, high molecular weight polymer (hyaluronic acid) is mixed with a positively charged peptide-based, self-assembling molecule, a membrane is instantaneously formed at the interface of the two solutions. These closed membranes (sacs) have a complex hierarchical structure which presents a unique challenge in quantifying its mechanical properties.
Molecular semiconductors are important materials for technology applications, such as solar cells. Current research focuses on how to organize molecules at interfaces for more efficient energy conversion. Maryland MRSEC researchers
Hydrogels undergo volume changes when immersed in water, the degree of which is det
The dipole orientation in ferroelectrics, such as LiNbO3 and BaTiO3, can be controlled via application of an electric field and this can in turn affect surface properties. In this project we have shown for b
We have designed and fabricated simple artificial protein scaffolds (we call them maquettes) that can transfer catalytic functions familiar in Nature into materi
The Roman God Janus has two faces, one to look forward plus one to look back, and now serves as inspiration for many to make ‘Janus particles’ with two (or more) functionalities. Indeed, the successful design and engin
In high speed devices, electrons are accelerated to high energy by a high electric field; to understand device performance, it is important to know how those “hot” electrons relax by scattering with each other and with the environment (the graphene lattice and the SiC substrate).
