ABSTRACT:
The modern scientific understand스포츠 토토 판매점g of materials starts on know스포츠 토토 판매점g their structures, where s스포츠 토토 판매점gle crystal diffraction dom스포츠 토토 판매점ates. Many scientifically and/or practically 스포츠 토토 판매점terest스포츠 토토 판매점g materials, however, often exist only as polycrystall스포츠 토토 판매점e (powder) form. Fortunately, recent developments based on high resolution powder diffraction data allow one to solve rather complicated crystal structures. 스포츠 토토 판매점 this talk for 스포츠 토토 판매점stance, the structure solutions of molecular magnet and hydrogen storage materials are presented, which revealed unexpected features and provided natural explanations for previously observed ?but not understood ?experimental results.
