Journal of Analytical Methods in Chemistry, Volume 13, Issue 5, Page 187-197, 1991., 1991 A versatile automated synthesis apparatus, equipped with a chemical artificial intelligence, was developed to prepare and isolate a wide variety of compounds. The apparatus was to the synthesis of substituted N‐(carboxyalkyl)amino‐acids. The apparatus [1,2] is composed of units for performing various tasks,for example reagent supply, reaction ...

Zoologica Scripta, Volume 53, Issue 6, Page 818-838, November 2024.Abstract The superfamily Stromboidea is a clade of morphologically distinctive gastropods which include the iconic Strombidae, or ‘true conchs’. In this study, we present the most taxonomically extensive phylogeny of the superfamily to date, using fossil calibrations to produce a chronogram and extant geographical distributions to reconstruct ancestral

Calcite Twinning in Mollusk Shells and Carrara Marble
Advanced Functional Materials, Volume 34, Issue 35, August 28, 2024.Deformation twinning occurs in Carrara marble and appears in polarized light microscopy as parallel lines in calcite crystals (bottom left). Twins are known to harden and toughen calcite crystals. Twins are never observed within mollusk shell calcite prisms (top left).
