Nanoindentation based techniques were significantly enhanced by continuous stiffness
monitoring capabilities. In essence, this allowed to expand from point-wise discrete …

This review is a follow up to Grün et al.(2006): Direct Dating of Human Fossils. Since that
time there has been progress on the experimental side of the geochronological analyses …

Materials displaying negative Poisson's ratio, referred to as auxeticity, have been found in
nature and created in engineering through various structural mechanisms. However, uniting …

Hard dental tissues possess a complex hierarchical structure that is particularly evident in
enamel, the most mineralised substance in the human body. Its complex and interlinked …

Dental enamel is a specialized tissue that has adapted over millions of years of evolution to
enhance the survival of a variety of species. In humans, enamel evolved to form the exterior …

Living organisms in nature have undergone continuous evolution over billions of years,
resulting in the formation of high-performance fracture-resistant biomineralized tissues such …

Background The radula, a chitinous membrane with embedded teeth, is one important
molluscan autapomorphy. In some taxa (Polyplacophora and Patellogastropoda) one tooth …

Objectives Enamel prism decussation, which manifests as Hunter-Schreger Bands (HSB), is
considered a mechanism to mitigate crack propagation. During the chewing cycle, the …

Human enamel is an incredibly resilient biological material, withstanding repeated daily
stresses for decades. The mechanisms behind this resilience remain an open question, with …

The molluscan radula, a thin membrane with embedded rows of teeth, is the structure for
food processing and gathering. For proper functioning, radular failures must be either …
