Optimising Mass Transfer in Synthetic Porous Materials
The performance of materials is determined by their intricate structures. A primary example can be seen in hierarchically porous materials. Their characteristic multi-level networks facilitate efficient mass transfer through larger pores and increase the specific surface area via smaller branching …

'Insidious Pollen': Literature and Industrial Toxicity, 1935-Present
… sensory experiences: tactile encounters with new synthetic materials, for example, or exposure to invisible toxicants. They also respond to difficult questions of systemic complicity and frustrated agency. While some of these texts overtly call their readers to political action, others voice how …

Nanoscale influences on bioactivity : ultrastructure and nanomechanics of model bioactive hydroxyapatite based biomaterials
There is a significant need for improved synthetic materials as orthopedic implants to replace human bone lost and damaged due to disease or injury. Certain ceramics, such as hydroxyapatite (HA), have the special property of being bioactive, meaning that an interfacial bond between the implant and …
