Abstract:
A selective adhesive mechanism comprises an engineered surface structure or substrate and a compliant member. The compliant member is able to be a dry and non-tacky substance. The compliant member is selectively adhesive to the engineered surface when the compliant member is in contact with the engineered surface. The compliant member shows adhesion to the engineered surface when the compliant member is within a pre-selected range of hardness. In some embodiments, the compliant member comprises a polymeric member, a thermoplastic elastomer, silicone, polyurethane, or a combination thereof.
Abstract:
A dry adhesive comprising a micro-featured and nano-featured surface, and a compliant surface having a hardness of about 60 Shore A or less, the micro-featured and nano-featured surface and the compliant surface being capable of forming upon contact a dry adhesive bond with each other.
Abstract:
Manipulators for handling micron-scale samples, methods for making probes for the manipulators, and methods for using the manipulators are provided. An exemplary manipulator includes a probe, a probe holder, and a mechanical positioner. The probe includes an electrically conductive surface, a proximal end and a distal end where the distal end has a truncated conical shape with a generally flat face, and a bore extending from the proximal end to the face. The probe holder engages the proximal end and includes an inlet in fluid communication with the bore and with a source of sub-ambient pressure. An exemplary microscopy inspection method includes forming a free-standing membrane, positioning the probe of the manipulator proximate to the membrane, drawing the membrane to the face by drawing a vacuum through the bore, placing the membrane on a sample support, and inspecting the membrane with a microscope.
Abstract:
A fruit or vegetable cleaning device comprising a lid and a bowl. The bowl has a plurality of vertical blades dividing the bowl into a plurality of chambers, each blade having a plurality of circular opening near the center of the bowl and elongated openings proximal to a bowl wall; and the bowl having openings on a part of a bowl edge and said lid having a recessed edge with opening thereon, said lid recessed edge adapted to be inserted into said bowl edge, said lid recessed edge openings and said bowl edge openings having a first mode exclusive of each other to form a leak proof enclosure to shake the fruit or vegetable and a second mode inclusive of each other to allow liquid to be drained away from said bowl; and a circular screen positioned below said vertical blades.
