The combination of bottom-up and top-down processes to organize nanophases in hybrid materials is a key strategy to create functional materials. We found that oxide and sulphide nanocrystals become spontaneously dispersed in organic media during the self-assembly of nanoribbon supramolecular polymers. These nanoribbon polymers form by self-assembly of(More)
Molecular self-assembly offers an effective method to modify the surface properties of common biomaterials by presenting biologically relevant chemistry in a controlled, ordered fashion. This work reports on self-assembling triblock molecules containing rigid cholesteryl segments followed by flexible oligomers of L-(lactic acid) and second generation(More)
The operational performance of gears regarding smoothness, quietness, wear and life span is largely affected by how gear and pinion teeth make contact. And the geometric characteristic of teeth profile plays a very important role in influencing contact condition during gear transmission. For a nominal involute gear pairs, load concentration on the(More)
Public Reporting burden for this collection of infonnation is estimated to average 1 liour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information.

In this paper, a flexible tension-pressure tactile sensitive sensor array is proposed for intelligent robot skin to detect external pressure in the case of tensile and bendability condition. Such flexible sensitive tension-pressure tactile sensor is fabricated with carbon nanotubes (CNTs) and carbon black (CB) as conductive filler and silicone rubber as(More)
We report on the influence of molecular chemical structure on second harmonic activity in several homologous series of self-assembling short chain polymers containing both molecularly rigid and flexible segments and known to form supramolecular nanostructures. The second-order nonlinear optical susceptibility and physical structure of films formed by these(More)
