摘要:
Provided is a method of manufacturing porous ceramic bodies with gradient of porosity, in which a gradient that is continuous to a pore size and porosity is precisely controlled in a simple way. The method includes the steps of: obtaining molded bodies by pressurizing and molding a mixture of powder obtained by mixing ceramic powder and polymer powder at a weight ratio of 1:1 to 100:1; and obtaining sintered bodies with gradient of porosity by sintering the molded bodies while applying a gradient pressure to the molded bodies.
摘要:
One-dimensional ring structures from M13 viruses were constructed by two genetic modifications encoding binding peptides and synthesis of a heterobifunctional linker molecule. The bifunctional viruses displayed an anti-streptavidin peptide and hexahistidine (SEQ ID NO:4) peptide at opposite ends of the virus as pIII and pIX fusions. Stoichiometric addition of the streptavidin-NiNTA linker molecule led to the reversible formation of virus-based nanorings with circumferences corresponding to lengths of the packageable DNAs. These virus-based ring structures can be further engineered to nucleate inorganic materials and form metallic, magnetic, or semiconductor nanorings using trifunctionalized viruses.

摘要:
The present invention provides for novel peptoid oligomers that are capable of self-assembling into two-dimensional sheet structures. The peptoid oligomers can have alternately hydrophilic or polar side-chains and hydrophobic or apolar side-chains. The peptoid oligomers, and the two-dimensional sheet structures, can be applied to biological applications where the peptoid plays a role as a biological scaffold or building block. Also, the two-dimensional sheet structures of the present invention can be used as two-dimensional nanostructures in device applications.

摘要:
The invention is directed toward systems and methods for the formation of two dimensional monolayer structures of ordered biomacromolecules, such as viruses, atop cohesive polyelectrolyte multilayers to create functional thin films. Methods for the formation of such thin films are disclosed that involve an interdiffusion-induced assembly process of the biomacromolecules. The inventive systems provide a general platform for the systematic incorporation and assembly of organic, biological and inorganic materials and will enable many potential technological applications such as, for example, chemical and biological sensors, power devices and catalytic membranes.
