Disclosed is a method for preparing a ternary alloy catalyst with polydopamine coating and a ternary alloy catalyst prepared thereby. The method for preparing a ternary alloy catalyst according to the present disclosure may provide a ternary alloy catalyst with increased resistance to carbon monoxide (CO) poisoning in which polydopamine is utilized as a coating material for a ternary alloy catalyst having a core-shell structure containing platinum to suppress the growth of particles during subsequent high-temperature heat treatment, and nickel (Ni), which is a transition metal, is diffused inside to form a core, thereby effectively preventing elution of nickel under an acidic condition.

An electronic apparatus includes a camera module including an optical image stabilizer (OIS) module and an image sensor, and at least one processor. The at least one processor is configured to control the camera module to calculate an error based on an operation of the OIS module responsive to movement of the electronic apparatus during at least part of time of the first exposure, to interrupt the first exposure and obtain a first image corresponding to the first exposure, based on the fact that the calculated error exceeds a critical value, to obtain a second image corresponding to the second exposure, and to generate a third image, in which at least part of the movement is corrected, by using the first image and the second image.

An electronic device includes a lens part that receives light from a subject, an image sensor that receives the light of the lens part from a group of pixels arranged two-dimensionally, and an processor that processes an image signal of the image sensor. The image sensor performs a read-out operation at a speed to prevent blurring of an image. The processor temporarily stores image data by the read-out operation in a memory, loads a plurality of images stored in the memory to generate an image, of which the number of bits is expanded compared with the image signal of the image sensor, and performs gamma processing on the image, of which the number of bits is expanded, to generate an image compressed to the same number of bits as the image signal of the image sensor.

A method of producing a catalyst including a platinum-transition metal alloy on carbon, more specifically, a method of producing a carbon supported platinum alloy catalyst with high activity and superior durability includes coating a carbon-supported catalyst with an organic polymer as a material for a carbon layer, heat-treating the catalyst under a hydrogen-deficient atmosphere to convert the organic polymer into the carbon layer to prevent growth of catalyst particles caused by heat treatment through the carbon layer, allowing, at the same time, a transition metal supported together with platinum to be diffused into platinum particles to form a catalyst having a core-shell structure including a platinum skin layer on a surface thereof, and removing the carbon layer by ozone treatment after the heat treatment to induce an electrochemical reaction on the surface of the catalyst.

Techniques herein prepare an alloy catalyst using a protective conductive polymer coating. More particularly, an alloy catalyst is prepared by: preparing a platinum catalyst supported on carbon; coating the surface of the platinum catalyst with a conductive polymer; supporting a transition metal salt on the coated catalyst; and heat treating the catalyst on which the transition metal salt is supported. Also, an alloy catalyst may be prepared by: preparing a platinum-transition metal catalyst supported on carbon; coating the surface of the platinum-transition metal catalyst with a conductive polymer; and heat treating the coated catalyst. Accordingly an alloy catalyst with superior dispersity can be prepared by increasing the degree of alloying of the catalyst through heat treatment while preventing the increase of catalyst particle size through carbonization of the conductive polymer. The prepared catalyst may be useful, for example, for a fuel cell electrode.

An image forming apparatus and a method of controlling the same capable of preventing an unnecessary repetitive performance of a scan task by sensing in advance a succeeding scan command generated with respect to a document which has already been scanned and using a previous scan result without an additional scan task are provided. The method includes generating and storing a first image through a first scan task according to a first scan command, determining whether a document at the first scan task is replaced by a new document using document sensors if a second scan command is generated, and using the first image as a result of the second scan command without performing a second scan task according to the second scan command upon determining that the document at the first scan task is not replaced by the new document.

Disclosed is an apparatus for measuring a shearing force upon sitting in a seat in a vehicle. The apparatus includes a shearing force sensor, a signal processor, and a monitoring device. The shearing force sensor is disposed in a compartment in a seat and senses the shearing force generated upon sitting on the seat. The signal processor filters and amplifies a signal from the shearing force sensor, and converts an amplified analog signal into a digital signal. The monitoring device analyzes the signal converted by the signal processor and displays the signal. As a result, the apparatus measures all directions of shearing forces generated upon sitting.
