TL;DR: In this paper, the local structure and effective chemical valency of Mn impurity atoms incorporated in wideband-gap (Ga,Mn)N epilayers have been investigated by using x-ray absorption fine structure techniques.
Abstract: Local structure and effective chemical valency of Mn impurity atoms incorporated in wide-band-gap (Ga,Mn)N epilayers have been investigated by using x-ray absorption fine structure techniques. The x-ray results provide direct evidence for the substitution of majority Mn atoms for the Ga sites in GaN, with an effective valency close to Mn(II), up to a rather high Mn concentration about 2 at. %. A small fraction of the impurity atoms could also form Mn clusters.

TL;DR: In this paper, the binding activity of non-polymeric valency platform molecules and conjugates comprising chemically defined, nonpolymeric, and biological or chemical molecules including polynucleotide duplexes of at least 20 base pairs for human lupus anti-dsDNA autoantibodies was investigated.
Abstract: Chemically-defined, non-polymeric valency platform molecules and conjugates comprising chemically-defined valency platform molecules and biological or chemical molecules including polynucleotide duplexes of at least 20 base pairs that have significant binding activity for human lupus anti-dsDNA autoantibodies.

TL;DR: In this article, a review of electron paramagnetic resonance (EPR) research of substitutional defects in ABO3 double oxides crystallizing in the perovskite structure is given.
Abstract: 2014 A review is given of electron paramagnetic resonance (EPR) research of substitutional defects in ABO3 double oxides crystallizing in the perovskite structure. In section 2, the valency and lattice sites are considered. In section 3, the existence of transition metal-oxygen vacancy pairs, Me-Vo, is reviewed, and in 4, their atomic structure is analysed. In section 5, the determination of the local position of Fe3+ at B sites in crystals undergoing ferroelectric phase transitions is presented, and its anomalously low cubic splitting EPR parameter discussed in 6.
