31.   The highly compressed molecular structure resembled that of cubic boron nitride, the second-hardest of all known substances, exceeded only by diamond.

32.   The idea is to more accurately analyze data by focusing on the three-dimensional molecular structure of chemicals and to better design libraries of chemical compounds, said Siran.

33.   The study is aimed at identifying how defects form in the molecular structure of the zeolyte as it is produced.

34.   Using infrared spectroscopy and X-ray crystallography to examine the molecular structure of the material, the scientists confirmed that the specks were diamond.

35.   When their normal molecular structure mysteriously folds into new shapes, they become infectious and cause diseases.

36.   Benwitz said firing the weapon was too risky because its molecular structure might have been altered.

37.   Boretta and Montagnier note in their article that only a small number of people appear to have such protection due to the molecular structure of their cells.

38.   Brain diseases such as BSE, scrapie and CJD are thought to be caused by alterations to the molecular structure of proteins called prions.

39.   But they have different molecular structures, Rosen said.

40.   Developing methods to determine molecular structure of crystals.
