At the smallest length scales, disordered systems such as nanoparticle packings and glass resemble the grains of sand on a beach. Lacking a structure, it is very difficult to understand how they deform and flow. We use a technique called atomic force microscopy, in which a sharp probe “feels” and pokes at a sample to measure its shape and mechanical properties.
Hybrid cell-like vesicles were prepared by coassembling (glyco)dendrimersomes with bacterial membrane vesicles (BMVs) derived from E. Coli. These assemblies incorporated transmembrane proteins such as the small fusion protein MgrB tagged with a red fluorescent protein, and glycoconjugates such as lipopolysaccharides and glycoproteins from E. Coli.
Building complex three-dimensional (3D) materials from pre-programmed two-dimensional films presents exciting challenges and opportunities. To achieve this goal, researchers inspired by the paper folding techniques of origami and kirigami have successfully utilized the mechanical instabilities of thin films, such as buckling.
Probing and manipulating electronic band structures of 2D materials.
Study reveals thin film physics also manifests in random nanocomposite geometry.
In Through the Looking Glass, Alice steps through a mirror into a world in which everything is its mirror image. Realizing that writing in books is reversed, Alice wonders what has happened on the atomic scale.
The goal of this seed project is to bring first-principles theory closer to experimental reality.
Electricity is the flow of charged particles through a material, such as a wire — a process that resembles a river of water molecules flowing through a canyon. But are the charged particles positive or negative?
