Abstract: A quantum dot ensemble of an embodiment of the present disclosure includes a plurality of quantum dots (120) each including a core (121) including a compound semiconductor and a shell layer (122) including one or more organic ligands (122A) coordinated to a surface of the core (121) and an oxide film (122B) that covers a portion of the surface of the core (121) to which the one or more organic ligands (122A) are not coordinated, and adjacent quantum dots of the plurality of quantum dots (120) are adjacent through the one or more organic ligands (122A) or the oxide film (122B).

Abstract: A quantum dot includes a core and a shell. The core includes a compound semiconductor and has a polyhedral shape. The polyhedral shape includes multiple surfaces and a vertex at which multiple edges between the surfaces adjacent to each other converge. The shell is provided at the surfaces and has a thickness at the part around the vertex in a vertical direction with respect to any one of the surfaces. The thickness is greater than a thickness at a part other than the part around the vertex in the same direction.

Abstract: An imaging element according to an embodiment of the present disclosure includes a photoelectric conversion layer including an organic photoelectric conversion material, a hole transporting material, and an electron transporting material, in which the electron transporting material includes a fullerene compound monomer and a fullerene compound dimer.

Abstract: An imaging device including a photoelectric conversion layer including a semiconductor nanoparticle (100) including a particle body (101) and a monoatomic ligand (102). The particle body (101) includes a semiconductor core (103) including at least two or more elements selected from a Group I element, a Group III element, a Group V element, and a Group VI element. The monoatomic ligand (102) is bonded to a surface of the particle body (101).

Abstract: A manufacturing method of a quantum dot ensemble of the present disclosure is a manufacturing method of a quantum dot ensemble including a plurality of core-shell quantum dots 10A that each includes a core 10B including a compound semiconductor, and a shell 10C including a compound semiconductor and covering the core, and a ligand 10D coordinated to the shell, and the manufacturing method includes mixing a core material, a shell material, and the ligand in a solvent and thereafter performing heating to thereby form the core-shell quantum dots, coordinate the ligand to the shell, and cleave the ligand.

Abstract: Provided is a stringed instrument using frets, in which a low-pitched sound range is extended without changing the size of the main body and the sound range before the low-pitched sound range has been extended can be restored by using a capotasto.

Abstract: A fluid-damped elastomeric bushing has an inner sleeve and an outer sleeve disposed outwardly of the inner sleeve, and two sidewalls extending between the inner sleeve and the outer sleeve and a partition wall to thereby form a pair of fluid compartments. The fluid compartments has a main chamber and a supplemental chamber in communication with the main chamber. An elastic support member extends radially outwardly from the inner sleeve toward the outer sleeve between the side walls to form a first main chamber and a second main chamber.An orifice device is disposed circumferentially along the outer sleeve for communicating the first and second main chambers for causing a fluid in one of the first and second main chambers to be forcibly fed to the other one of the first and second main chambers when a load is applied to the bushing.

Abstract: A fluid-damped elastomeric bushing of the invention comprises an inner sleeve and an outer sleeve in a concentric or eccentric relation, an elastric member provided between the inner and outer sleeve, a plurality of liquid chambers or compartments provided in the central portion of the elastic member with respect to the axial direction of the sleeve, the liquid compartments being arranged along the circumference at specified intervals, and orifices to communicate at least the adjacent liquid compartments with each other. The elastic compartment wall of the elastic member has a portion bent toward the interior of the liquid compartment. A central part of the elastic compartment wall may have its thickness reduced relative to the other part.
