Abstract: A storage rack for nuclear fuel assemblies, comprising a rigid structure defining a plurality of adjacent cells, and comprising in each cell a sleeve defining a cavity intended to receive a nuclear fuel assembly, the sleeve having, in cross-sectional orthogonal to the longitudinal direction, a generally polygonal shape whereof the sides are produced using plates made from a neutron-absorbing material. According to the invention, the sleeve also includes: profiles each forming a corner piece, arranged on at least several angles of the generally polygonal cross-section, these profiles serving as a mounting bracket for the plates made of a neutron-absorbing material; and a structure for maintaining the profiles therebetween.

Abstract: The invention relates to a heterostructure including a first region (R1) made of a first n-doped semiconductor material, a second region (R2) made of a second p-doped semiconductor material and, between said first and second regions, a type-II superlattice (SR) made up of an alternation of layers (C1, C2) of a third and fourth semiconductor material, said layers being thin enough for the carriers to be displaced inside said superlattice, forming at least one electron mini-band (MBe) and one hole mini-band (MBh), the interfaces between the first region and the superlattice, between the layers of the superlattice and between the superlattice and the second region being mutually parallel. The invention also relates to a photovoltaic cell including such a heterostructure as an active element. The invention further relates to a solar panel including a combination of such photovoltaic cells.

Abstract: A method for capillary electrophoretic analysis of a biological sample, comprising using negatively surcharged modified antibodies so that they migrate to a zone located outside the migration zone for proteins from the biological sample when they are separated during electrophoresis is disclosed. The antibodies have antigenic specificity for a predetermined target protein.
