Dynamic Shear Deformation in Zinc Crystals [PDF]
, 1962 The initial stages of yielding in single crystals of zinc have been investigated at temperatures of -292°F (-180°C), -93°F (-70°C) and +75°F (24°C), by means of rapidly applied constant stress pulses to produce slip along the basal planes of these ...

Modelos discretos de dislocaciones en redes cristalinas: formulación, análisis y aplicaciones [PDF]
, 2007 Real crystal lattices are not perfect. They have defects such as dislocations, vacancies, and cracks that control the mechanical properties of materials, including crystal plasticity, creep, fatigue, ductility, brittleness, hardness and friction ...

Phyllotaxic diversity in Magnolia flowers
Acta Societatis Botanicorum Poloniae, 2014 Impermanent initials and thus the shift of the axis in the stochastic meristems are postulated to be responsible for ontogenetic phyllotactic diversity in plants.

Gradient self-organized dislocation in expanded austenite layer during low-temperature nitriding
Materials Research Express, 2023 A typical nitrogen expanded austenite layer is formed by plasma-based low-energy nitrogen ion implantation (PBLEII) on AISI 304L austenitic stainless steel at a moderate temperature of 380 °C.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
