    Abstract: Provided is an Fe-based soft magnetic alloy. An Fe-based soft magnetic alloy is represented by the empirical formula XaBbSicCudMe, wherein: X includes Fe and at least one element among Ni and Co; M includes at least one element among Nb and Mo; a, b, c, d, and e indicate the atomic percents (at %) of corresponding elements, in which 15.0≤b+c≤19.0, 0.5≤d≤1.5, and 2.0≤e≤5.0; and X is included as the remainder. Accordingly, the Fe-based soft magnetic alloy has high saturation magnetic flux density and low magnetic loss characteristics, and thus can be very easily used in various parts using magnetic materials. In addition, since the effect of heat treatment conditions can be minimized during the realization of uniform and small crystal grains after heat treatment, process conditions can be easily designed, so that the Fe-based soft magnetic alloy is very suitable for mass production.

    Abstract: A method of manufacturing a heat dissipation sheet including preparing a preliminary sheet including a matrix-forming component, a crosslinking agent, and a heat dissipation filler, and crosslinking the matrix-forming component included in the preliminary sheet and thus obtaining a heat dissipation sheet. The heat dissipation sheet manufactured has remarkably excellent heat dissipation properties because it contains a high content of heat dissipation filler. Due to the material properties of the matrix-forming component and the crosslinking of the matrix-forming component and the resulting matrix formation, the occurrence of cracking, shrinkage, pore formation, thickness change, and the like is minimized or prevented, and excellent flexibility can be attained. Moreover, since processability is improved through processes such as cooling when manufacturing the heat dissipation sheet, productivity is excellent, and the sheet can be suitable for mass production.

    Abstract: Provided is a fiber web for a gas sensor. In one exemplary embodiment of the present invention, there is provided a fiber web for a gas sensor including nanofibers including a fiber-forming material and a sensing material for reacting with a target substance in a test gas. According to the exemplary embodiment, the fiber web for a gas sensor is capable of identifying the presence or absence of a target substance in a test gas and quantitatively determining the concentration of a target substance, and exhibits improved sensitivity due to having an increased area of contact and reaction with a target substance contained in a test gas. In addition, the fiber web for a gas sensor facilitates the detection of a target substance in a test gas at a low cost and thus can be widely used for the detection of various volatile organic compounds (VOCs) in households, the diagnosis of asthma or esophagitis or the identification of a patient suffering from the same, and the detection of hazardous materials in other fields of industrial safety.

    Abstract: A method for manufacturing a fiber assembly for providing a binding surface to a bio-substance is provided. A fiber assembly for providing a binding surface to a bio-substance according to an embodiment of the present invention is manufactured by a method comprising the steps of: (1) preparing a fiber assembly in which a plurality of fibers is accumulated; and (2) performing modification to provide the fiber surface with a carboxyl group reactive to an amine group present in a bio-substance. According to the method, a bio-substance can be easily introduced at a high content into the fiber assembly. In addition, bio-substances that are conjugated therebetween and adsorbed through physical adsorption, etc. are remarkably reduced in the introduction procedure of bio-substances, whereby bio-substances can be availed with high precision and reliability in applications employing bio-substances. Furthermore, applications employing bio-substances can undergo minimal property variations attributed to the bio-substances as detachment of the bio-substances is minimized or prevented. Accordingly, the bio-substances fixed on the surface of the fiber assembly according to the present invention can find a broad spectrum of applications in various fields including the material engineering, bio engineering, medical fields, and so on.
