(1995), M41S: A new family of mesoporous molecular sieves prepared with liquid crystal templates. Science and Technology in Catalysis 1994 Studies in Surface Science and Catalysis, 92, 11-19.

Abstract: The use of cationic surfactants as the structure directing agents resulted in the discovery of the first mesoporous aluminosilicate molecular sieves. One class of materials within this extensive and diverse family possesses a hexagonal array of uniform pores. This dass is designated MCM-41 and the pore size can be tailored in the range 15 to 100 Angstrom. The presence of discrete large pores in MCM-41 is reflected in their high adsorption capacity and some unique features, such as capillary condensation without hysteresis. Other distinct members of the mesoporous family include materials denoted MCM-48 with a well-defined structure having cubic symmetry.

These aluminosilicate systems have shown behavior parallel to that of lyotropic liquid crystals including certain phenomena peculiar to the surfactant systems. The latter include the aforementioned structural diversity, and pore size variation in response to either change of surfactant chain length or the presence of swelling organic agents. To explain the formation and properties of the new molecular sieves, a liquid crystal templating mechanism has been proposed.

Abstract: Do researchers produce scientific and technical knowledge differently than they did ten years ago? What will scientific research look like ten years from now? Addressing such questions means looking at science from a dynamic systems perspective. Two recent books about the social system of science, by Ziman and by Gibbons, Limoges, Nowotny, Schwartzman, Scoff and Trow, accept this challenge and argue that the research enterprise is changing. This article uses bibliometric data to examine the extent and nature of changes identified by these authors, taking as an example British research. We use their theoretical frameworks, to investigate five characteristics of research said to be increasingly pervasive-namely, application, interdisciplinarity, networking, internationalization, and concentration of resources. Results indicate that research may be becoming more interdisciplinary and that research is increasingly conducted more in networks, both domestic and international, but the data are more ambiguous regarding application and concentration.

Abstract: Despite a growing interest in gender differences in scientific careers, few studies have focused an the impact of research organization on researchers. This article offers a new approach to this issue by introducing bibliometric maps combined with sociological data and interviews, taking both the research organization and the experiences of the individual researcher into account. The results indicate that gender blares operate at various levels of the research organization and are often imbedded in seemingly gender-neutral processes and practices in the everyday working life of researchers.

Abstract: This article focuses on a crucial development in genetic research that occurred in the 1990s: the identification of the first two of the genes responsible for hereditary breast and ovarian cancer (BRCA I and BRCA2). Issues addressed touch on the evolution of the subfield, its potential impact on cancer treatment, and industry, involvement. The article follows the activities of the various research groups competing in the race to identify the genes and depicts the frequent conflicts between them. Data are derived chiefly from a bibliometric database. The results show a diversity of research practices. Industrial researchers interacted within jar more tightly knit networks than their counterparts working in public organizations. The patenting and commercial exploitation of results led to fierce battles, with one group capturing most of the benefits.
