Abstract: A nano-twinned crystal film and a method thereof are disclosed. The method of fabricating a nano-twinned crystal film includes utilizing an electrolyte solution including copper salt, acid, and a water or alcohol-soluble organic additive, and performing electrodeposition, under conditions of a current density of 20˜100 mA/cm2, a voltage of 0.2˜1.0V, and a cathode-anode distance of 10˜300 mm, to form the nano-twinned crystal film on a surface at the cathode. The nano-twinned crystal film formed by the method includes a plurality of nano-twinned copper grains and a region of random crystal phases between some of adjacent nano-twinned copper grains, wherein at least some of the nano-twinned copper grains have a pillar cap configuration with a wide top and a narrow bottom.

Abstract: A frame assembly for eyeglasses includes a frame including two rims and two extensions that extend from two ends of the frame. Each extension has two slots. Two connection members each have a board and two lugs that extend from one side of the board. Each lug has a hole defined therethrough. The two lugs of each connection member are inserted into the two slots corresponding thereto. Two temples each have a first slit defined longitudinally in one end thereof so as to define two flexible parts. Each part has a protrusion extending from an outside thereof and the two flexible parts of each temple are located between the two lugs of each connection member and the two protrusions are engaged with the two holes of the two lugs of each connection member.
