网页2016年9月23日 — The first mesostructure is made of PI (green), the second one is made of PI (green) and copper/PI bilayers (orange), the third structure is made of epoxy (SU8, yellow), the fourth and fifth mesostructures are made of copper/PI bilayers, and the last three structures are made of plastic films.
Morphable 3D mesostructures and microelectronic devices by …
网页2018年1月29日 — An array of silicon n-channel metal-oxide–semiconductor field-effect transistors (n-MOSFET) integrated onto a shape-shifting 3D mesostructure framework serves as an example in high-performance ...
An example of the mesostructure-structure system. It is to be …
网页Selecting the optimal mesostructure design for each element is a critical step in system optimization. The density level is represented by volume fraction (VF) of the material phase in a unit...
网页The mesostructure level represents geometric details that are relatively small but still individ-ually visible such as bumps or dents on a surface. Ef -cient mesostructure reconstruction methods can contribute greatly to high-quality graphics models in terms of ne-scale surface geometric details.
Geometrically reconfigurable 3D mesostructures and ... - Science
网页2020年7月22日 — Here, we present a mechanically guided scheme and bottom-up design strategy to enable the construction of geometrically reconfigurable three-dimensional (3D) mesostructures on an elastomer substrate by using simple straight/curvy ribbon components as building blocks.
Composite mesostructures by nano-confinement - Nature Materials
网页2004年10月17日 — The systematic definition of periodic structure as a function of cylindrical confinement for either organic or composite systems remains to be determined. Here we describe the morphogeneses of new...
Mesostructure Design with Gemini Surfactants: Supercage …
网页1995年6月2日 — Gemini surfactants, with two quaternary ammonium head groups separated by a methylene chain of variable length and with each head group attached to a hydrophobic tail, can be used to control organic charge sitting relative to the bivariable hydrophobic tail configurations.
