Separation of alkyl-substituted indene enantiomers by chromatography on microcrystalline triacetylcellulose

Abstract Some chiral alkyl-substituted indenes were separated into enantiomers by liquid chromatography on swollen microcrystalline triacetylcellulose. The influence of the alkyl substituents R 1 and R 3 on the separation and retention was investigated.

Ignoring Half the Sky: A Feminist Critique of Science Education’s Knowledge Society

A Chinese proverb observes that women ‘hold up half the sky’, yet often in science education we have ignored the knowledge generated by feminist researchers about how females engage and participate in science. Further, science education has often failed to consider the implications from feminist critiques of science on science education. This chapter will provide a feminist perspective on who generates knowledge in science education and what knowledge is acceptable as ‘scientific’ by the field. Second, we will discuss the culture of science education and discuss whether science educators value the knowledge produced by gender and feminist researchers. In particular, we will examine the integration (or lack thereof) of gender issues into the dominant areas in science education research, such as teachers’ pedagogical content knowledge, the development of students’ science knowledge through inquiry, the role of conceptual change, and teachers’ preparation and professional development programmes. Third, we will provide examples of how gender theory and feminist perspectives in science education could generate new knowledge about gender and science education.

Primary 2H kinetic isotope effects in the base-catalysed 1,3-prototropic rearrangement of 1-methylindene and 1,3-dimethylindene

Rate constants and primary deuterium kinetic isotope effects (p.d.k.i.e.s.) have been determined for the base-catalysed rearrangement of 1-methylindene (1) and 1,3-dimethylindene (3) in the solvent o-dichlorobenzene at 30°C. The structurally similar tertiary amines 1-aza-adamantane, quinuclidine, 1,3-diaza-adamantane, DABCO, and 1,3,5-triaza-adamantane were used as catalysts. Substrate (3) gave a lower isotope effect than (1). The response in p.d.k.i.e. due to a change in basicity of the amine catalyst is very similar for (1) and (3). Despite its intermediate basicity, DABCO showed a significantly lower p.d.k.i.e. for both substrates. The p.d.k.i.e.s. obtained for the other bases, with a pK at or around 2.6, were almost constant. The consequences of a possible influence of internal ion-pair return on the rearrangement of the substrates are discussed and related to the measured p.d.k.i.e.s. The similarity between the substrates and the symmetry in the rearrangement of (3) permits some rationalizations to be made.

Kinetic study of a homodienyl‐[1,5]‐hydrogen shift in a vinylzaziridine

The thermal rearrangement of an N-substituted vinylaziridine to the corresponding (Z)-allylic imine, i.e. a homodienyl-[1,5]-hydrogen shift, was studied at different temperatures in the range 40-90 degrees C. H-1 NMR spectroscopy was used to follow the r

Interstitial Spaces: A Model for Transgressive Processes

The chapter introduces the concepts of interstitial spaces and transgressive identities to examine the boundaries of gender and feminist studies, science, and education and discuss our research practices and positions. We use a metalogue as the vehicle for analyzing our autobiographies to provide examples when we have operated in interstitial spaces and engaged transgressive identities. Interstitial spaces exist between and within boundaries. These spaces are possible sites within a defined context (a discipline, a practice, a culture) that may be occupied by an actor/agent working as a “carrier” of different cultural practices, knowledge, and theories. A “carrier” can use the interstitial space to influence and challenge a “new” context and thus loosen up boundaries but can also by experiencing new cultures and developing new knowledge return to the “old” culture to integrate these new practices. Thus, interstitial spaces establish a context for transgressive identities to emerge so one can act in ways to transform and change the cultures of disciplines. We use transgressive identities as a theoretical description and understanding of our research practices and positions.

Witches, Alchemists, Poisoners and Scientists

Chemistry is a science well suited to the talents and situation of women; it is not a science of parade; it affords occupation and infinite variety; it demands no bodily strength; it can be pursued in retirement; it applies immediately to useful and domestic purposes; and whilst the ingenuity of the most inventive mind may in the science be exercised, there is no danger of it flaming the imagination, because the mind is intent upon realities, the knowledge that is acquired is exact and the pleasure of the pursuit is sufficient reward for the labour. (Edgeworth, 1795, p. 21)
