Exploring the Crystal Chemical Origins of Negative Thermal Expansion in Inorganic Framework Materials
Most materials shrink when cooled but some, such as ice, expand instead. This phenomenon, known as negative thermal expansion, is relatively rare and the mechanisms that give rise to it are only ...

Anne Sylvester, Univ of Wyoming, Cells at the Surface: Balancing cell division and expansion during differentiation of the maize leaf epidermis
Maize leaves emerge sequentially from stem cells around the base of the shoot apical meristem. As leaf primordia grow by cell division and expansion, a proximal-distal (P/D) developmental gradient is ...
