Patent
Electronics, Telecommunications Research Institute and Kongju National University | Date: 2014-09-02

A method and apparatus for transmitting a signal for channel estimation through a plurality of antennas are provided. A plurality of resources that are adjacent to each other in a time axis and a frequency axis are selected from among a set of resources that include a symbol in the time axis and a subcarrier in the frequency axis. Reference signals for the plurality of antennas are transmitted through the selected plurality of resources.

Provided is a method for producing Ag nanowires, including, heating a precursor solution that includes: an Ag salt; a water-soluble polymer; a surfactant, or a halide of metal ions having a standard reduction potential of 0.1 to 0.9V as a metal catalyst; and a reduction solvent, to produce the Ag nanowires. According to this method, a time for synthesizing nanowires may be considerably decreased, and an amount of Ag precursor discarded without reaction may be effectively reduced. As a result, the Ag nanowires may be produced with high efficiency and mass-production thereof through a simple scale-up may be successfully achieved.


Disclosed are a hydraulic binder composition using rapidly-cooled steelmaking reduced slag powder and a method of preparing the same. More particularly, the rapidly-cooled steelmaking reduced slag (RC-LFS) powder is obtained by spraying and scattering gas at a high pressure and high speed onto electric furnace smelting reduction slag, which is one of the by-products generated during iron smelting performed in an ironworks, and quickly cooling and pulverizing the slag. The initial high hydration heat reaction and initial setting of the rapidly-cooled steelmaking reduced slag (RC-LFS) powder are delayed to ensure workability. A retardant and gypsum are mixed into the rapidly-cooled steelmaking reduced slag (RC-LFS) powder so as to activate the generation of needle-shaped ettringite and to thus develop the initial and long-term strength, and therefore the rapidly-cooled steelmaking reduced slag (RC-LFS) powder of the present invention can be used as a substitute for ordinary Portland cement.
