20150017478 | METHOD OF SURFACE TREATMENT ON METAL OBJECT AND METAL OBJECT WITH GRADUAL PATTERNS - A method of surface treatment on the surface of a metal object includes a step of preparing multiple releasing sheets, each releasing sheet having at least one hollowed pattern; a step of attaching the releasing sheet on the metal object and the hollow patterns of the releasing sheets forming a figure; a step of grinding the surface of the metal object, the sandwheel removing material on the surface of the metal object via the hollowed pattern; a step of moving the releasing sheet, and a step of repeating the steps 2 to 4. The releasing sheet attached to the surface of the metal object of each of the repeated steps is different from the previous one. The sandwheels for grinding the metal object corresponding to the different releasing sheets have different roughness to obtain the figure. The metal object has an obvious figure and does not pollute the environment. | 01-15-2015 |

20150056471 | ORDERED POROUS NANOFIBERS, METHODS, AND APPLICATIONS - Described herein are nanofibers and methods for making nanofibers that have a plurality of pores. The pores have of any suitable size or shape. In some embodiments the pores are “mesopores”, having a diameter between 2 and 50 nm. In some embodiments, the pores are “ordered”, meaning that they have a substantially uniform shape, a substantially uniform size and/or are distributed substantially uniformly through the nanofiber. Ordering of the pores results in a high surface area and/or high specific surface area. Ordered pores, without limitation, result in a nanofiber that is substantially flexible and/or non-brittle. The nanofibers and methods for making nanofibers may be used, without limitation, in batteries, capacitors, electrodes, solar cells, catalysts, adsorbers, filters, membranes, sensors, fabrics and/or tissue regeneration matrixes. | 02-26-2015 |
20150099141 | DOUBLE COLD REDUCTION STRIP FOR SHADOW MASK AND PROCESS FOR PRODUCING THE SAME - The present invention discloses a double cold reduction strip for shadow mask and a process for producing the same, comprising the following procedures: converter steelmaking→continuous billet casting→hot rolling→pickling and cold rolling→continuous annealing→double cold reduction→finishing and oiling. The weight percentages of essential elements of the shadow mask strip are: C: ≦0.001%, Mn: 0.10˜0.40%, Al: 0.02˜0.06%, Si: ≦0.025%, P: ≦0.015%, S: ≦0.01%, O: ≦0.004%, with remainders composed of Fe and inevitable impurities. Through the composition design for the elements in steel material according to the present invention, on the one hand, the weight percentage of carbon is controlled at a low level; on the other hand, the middle decarburization annealing process is omitted, the annealing temperature is declined, the production period is shortened and the production cost is reduced; through the optimization for rolling parameters and roller processing in the double cold reduction, procedures for degreasing and finishing are removed, and steels with excellent mechanical property and high surface quality are obtained. | 04-09-2015 |
