    Abstract: An electroconductive bonding material contains a thermosetting resin, a low-melting-point metal powder which is melted at a temperature equal to or lower than the thermosetting temperature of the thermosetting resin, a high-melting-point metal powder which is not melted at a temperature equal to or lower than the thermosetting temperature of the thermosetting resin and which reacts with the low-melting-point metal powder to form a reaction product having a high melting point of 300° C. or higher during heat-hardening of the thermosetting resin, and a reducing substance which removes an oxide formed on the surface of the high-melting-point metal powder. The total content of the low-melting-point metal powder and the high-melting-point metal powder is 75% to 88% by weight, and the particle size ratio D1/D2 of the average particle size D1 of the low-melting-point metal powder to the average particle size D2 of the high-melting-point metal powder is 0.5 to 6.0. Thereby, an electroconductive bonding material is provided which has good conduction properties and high connection strength even when reflow heat treatment is repeatedly carried out or thermal shock accompanied with a rapid temperature change is applied to the electroconductive bonding material, and an electronic apparatus using such an electroconductive bonding material.

    Abstract: A printable composition for use in forming a printed element by printing and curing is described. The printable composition comprises a plurality of nanostructures of a first type that, upon printing and curing, form an arrangement defining intermediate volumes thereamong. The printable composition further comprises a plurality of nanostructures of a second type that, upon printing and curing, at least partially fill the intermediate volumes to promote smooth surface topography and reduced porosity in the printed element.
