Abstract: Provided are an electrolytic copper foil, an electrode and a lithium-ion cell comprising the same. The electrolytic copper foil has a first surface and a second surface opposite the first surface. An absolute difference of the FWHM of the characteristic peaks of (111) planes of the first surface and the second surface analyzed by GIXRD is less than 0.14, the first and the second surfaces each have a nanoindentation hardness of 0.3 GPa to 3.0 GPa, and the yield strength of the electrolytic copper foil is more than 230 MPa. By controlling the absolute difference of the FWHM of the characteristic peaks of (111) plane of these two surfaces, the nanoindentation hardness of these two surfaces and the yield strength, the electrolytic copper foil can have improved tolerance to the repeated charging and discharging and reduced warpage, thereby improving the yield rate and value of the lithium-ion cell.

Abstract: A semiconductor device includes a semiconductor substrate having a first region and a second region, insulators, gate stacks, and first and second S/Ds. The first and second regions respectively includes at least one first semiconductor fin and at least one second semiconductor fin. A width of a middle portion of the first semiconductor fin is equal to widths of end portions of the first semiconductor fin. A width of a middle portion of the second semiconductor fin is smaller than widths of end portions of the second semiconductor fin. The insulators are disposed on the semiconductor substrate. The first and second semiconductor fins are sandwiched by the insulators. The gate stacks are over a portion of the first semiconductor fin and a portion of the second semiconductor fin. The first and second S/Ds respectively covers another portion of the first semiconductor fin and another portion of the second semiconductor fin.

Abstract: A driving mechanism includes a condensing coil and a fan set above a body of a distilled water dispenser. The condensing coil has multiple layers of spiral coil formed by winding a stainless steel tube in a spiral on each of different horizontal planes. The stainless steel tube has one end thereof terminating in a steam inlet port and connected to an inner tank of the body, and an opposite end thereof terminating in a distilled water outlet port. The fan is used to drive air to the condensing coil so that the steam in the stainless steel tube is cooled and condensed into distilled water. This can achieve the purpose of improving the condensation efficiency, shortening the time required to generate distilled water, reducing the temperature of the distilled water outlet, and avoiding the use of radiating fins.

Abstract: A prokaryotic expression system or a recombinant adenovirus system is used to highly efficiently express VZV envelope gE glycoprotein and the flagellin fusion protein thereof. The produced recombinant gE protein, gE flagellin fusion protein and recombinant adenovirus vector, or composition thereof is used to immunize a mouse so as to promote the body to generate gE and VZV-specific antibody titer, as well as gE-specific and VZV-specific cell immunity.
