The present invention relates to a method for continuous removal of carbon dioxide, the method comprising the steps of: a) preparing an aqueous solution containing an amine-based compound and an acidic calcium compound; b) bringing a gas containing carbon dioxide to be treated into contact with the aqueous solution to prepare a calcium carbonate precipitate; and c) recovering the calcium carbonate and then adding a basic calcium compound to the residual aqueous solution, wherein after step c), step b) and step c) are repeatedly performed. The removal of carbon dioxide by the method of the present invention has advantages of requiring low energy and being capable of mineralizing and removing carbon dioxide at a fast rate without a separate time for induction.

Disclosed is a tire with reduced cavity noise including an adhesive agent layer applied to an inside of an inner liner and a sound absorber layer attached to the adhesive agent layer, wherein the adhesive agent layer includes poly(ether-urethane) containing alkoxysilane at both ends thereof. The tire with reduced cavity noise is stable without causing separation of a sound absorber even upon heating and deformation during driving.

The present invention relates to a method and an apparatus of preparing a reduction product of carbon dioxide by electrochemically reducing carbon dioxide. The present invention can prepare, in an energy-efficient manner, a reduction product of high-concentration carbon dioxide with high Faraday efficiency as in a liquid reduction reaction by producing the reduction product of carbon dioxide by supplying water or an electrolytic solution to an anode region; supplying humidified carbon dioxide gas having a second temperature higher than a first temperature to a cathode region within an electrochemical cell having the first temperature so as to supply the carbon dioxide gas which has been humidified to be in a condition where the relative humidity is greater than 100%, while applying a voltage between the anode region and the cathode region so as to generate hydrogen ions (H) in the anode region; and transporting the hydrogen ions to the cathode region through the electrolyte membrane, thereby electrochemically reducing the carbon dioxide gas.

The present invention relates to an airless tire, and includes first and second bands that face each other with a distance interposed therebetween, a plurality of spokes that connect the first band to the second band and are provided at intervals, and first and second connecting members that connect the adjacent spokes. The spoke includes a first member of which one end is curved from the first band toward the second band, and a second member of which one end is curved from the second band toward the first band. The other ends of the first and second members are connected to each other, and the first and second members are curved in opposite directions.

Disclosed herein is a non-pneumatic tire with a reinforcing member. The non-pneumatic tire includes a tread part which comes into contact with the ground, a rim part which is coupled to an axle, an outer annular band part which forms an interface with an inner surface of the tread part, an inner annular band part which forms an interface with the rim part, a spoke part which is disposed between the outer annular band part and the inner annular band part and functions as a support, a connector which connects spokes of the spoke part to each other, and a reinforcing member which has a plate wire structure. The non-pneumatic tire can effectively and sufficiently withstand the weight of a vehicle. Further, the performance of the tire is balanced with respect to the contact area, the displacement extent and the resistance to rolling.

A non-pneumatic tire for a vehicle is disclosed. The non-pneumatic tire includes a tread, a rim part, inside and outside annular bands, a spoke member, and a pair of protective films. The tread comes into contact with a road surface. The rim part is connected to the axle of a vehicle. The inside and outside annular bands are disposed between the tread and the rim part, and are coaxially spaced apart from each other. The spoke member includes supports disposed in a predetermined pattern and configured to connect the inside and outside annular bands, and openings defined by the supports. The pair of protective films are disposed at both ends of the tire in the widthwise direction of the tire, and prevents foreign substances from infiltrating into the openings of the spoke member. The protective films are made of the same material as the spoke member and integrated with the spoke member.

Disclosed herein is an airless are which absorbs shock and holds pressure applied to the tire through an auxetic spoke buffer without using air pressure. The airless tire includes a cylindrical tread being in contact with the ground, an axle fixing section having a smaller circumference than the tread and disposed inside the tread, and an auxetic spoke buffer connecting the tread and the axle fixing section and providing a buffering function. Accordingly, the airless tire is transformed only to an extent to properly function as a fire when the spoke buffer is transformed by pressure or impact and fully returns to an original shape when pressure or impact is removed.
