Abstract: A cooling system of the present disclosure includes: a coolant tank storing a coolant removing heat from a heating element in a closed space as an inner space; a plurality of heat pipes that are arranged to extend from the coolant tank toward the outside of the coolant tank and respectively having passages allowing the coolant as a working fluid to be movable therethrough; and a blower fan blowing air to the plurality of heat pipes from the outside of the coolant tank in a direction in which the heat pipes are arranged, wherein a cross-sectional shape orthogonal to the extension direction of each heat pipe is a flat plate shape having a leading edge on an upstream side of a blowing direction of the blower fan and a trailing edge on a downstream side thereof with the blowing direction as a longitudinal direction.

Abstract: An organic borane complex contains, as a component, triarylborane having an enhanced bonding between a boron atom and a carbon atom on an aryl group. The organic borane complex contains, as a component, triarylborane having a structure represented by the following general formula (1), wherein X1 and X2 each independently represent an oxygen atom or a sulfur atom; X3 and X4 each independently represent a hydrogen atom or a substituent, or X3 and X4 are linked together to be a single atom; R1 to R3 each independently represent a hydrogen atom or a substituent; and p, q and r each independently represent an integer of 1 to 3. Also disclosed are a composition containing organic borane, and an organic electroluminescent element.

Abstract: There are provided a ?-conjugated boron compound, an electronic device containing an organic functional layer including the ?-conjugated boron compound, a method for producing a triarylborane, and a method for producing a triarylborane intermediate. In the ?-conjugated boron compound, a boron atom is bonded to three aromatic groups via three boron-carbon bonds. Bond distances of the three boron-carbon bonds are all 1.48 ? or less.
