A lift cord concealable Venetian blind lift control mechanism is constructed to include a base having two hollow screw rods axially aligned at two sides and selectively mounted in the top or bottom rail of a Venetian blind, a revolving rod inserted through the hollow screw rods, a spring member, which provides a torsional force to the revolving rod, two bobbins respectively threaded onto the screw rods for synchronous rotation with the revolving rod. The left and right lift cords of the Venetian blind each have one end connected to the bottom or top rail and the other end fastened to the bobbin such that when the bottom rail of the Venetian blind lifted or lowered by an external force, the bobbins are synchronously rotated to wind up or let off the lift cords; when the external force disappeared, the bobbins are immovable, keeping the bottom rail in position.

Self-assembled nanowires are provided, comprising nanowires of a first crystalline composition formed on a substrate of a second crystalline composition. The two crystalline materials are characterized by an asymmetric lattice mismatch, in which in the interfacial plane between the two materials, the first material has a close lattice match (in any direction) with the second material and has a large lattice mismatch in all other major crystallographic directions with the second material. This allows the unrestricted growth of the epitaxial crystal in the first direction, but limits the width in the other.

A molecular memory system that includes a protective layer that is disposed over a molecular recording layer is described. The protective layer enables a scanning probe to write information to and read information from a molecular memory element by direct electrical contact without substantial risk of damage to either the scanning probe or the molecular recording medium. In this way, the invention avoids the high emission currents, which may damage the probe electrode or the recording media, or both, and avoids other difficulties often associated molecular memory systems with non-contacting probe electrodes.

摘要:
A method for detaching an epitaxial layer from one substrate and transferring it to another substrate allows an epitaxially grown material layer to be easily detached from a first substrate that has good epitaxial growth properties and transferred to another substrate having better cleaving, electrical or other properties than the first substrate. A mask is applied to a portion of a surface of the first epitaxial layer and a second epitaxial layer is grown over the first epitaxial layer and the mask. A trench is formed in the second epitaxial layer to expose the mask and a second substrate is bonded to the second epitaxial layer. An etchant is introduced through the trench and etches away the mask, thus releasing the second epitaxial layer from the first substrate and the first epitaxial layer. Thus, the second epitaxial layer has been released from the first substrate and transferred to the second substrate without performing operations that would impair the optical properties of the epitaxial material.

The present disclosure provides a resin composition, an adhesive-dropping material, an adhesive-pressing material, and a preparation method and application thereof. The resin composition comprises the following components: an ester-based prepolymer; a reactive diluent; and a photoinitiator; wherein the addition amount of the ester-based prepolymer is 60 to 80 parts by weight, the addition amount of the reactive diluent is 15 to 30 parts by weight, and the addition amount of the photoinitiator is 1 to 5 parts by weight, based on the part by weight. The artificial nail prepared by using the resin composition, the adhesive-dropping material, and the adhesive-pressing material according to the present disclosure has high mimicry. When in use, the artificial nail which is not completely hardened may be attached to the surface of the real nail and then hardened by UV light, so that the artificial nail is more conformable.
