A theoretical method to analyze the effect of stress distribution on compressive strength of periodic lattices

Materials & Design
The lattice structures or lattice metamaterials have been widely used in aerospace and medical fields, and the mechanical properties were mostly evaluated based on simulated stress distribution.

Comportamento dinâmico-mecânico e relaxações em polímeros e blendas poliméricas Dynamic mechanical behavior and relaxations in polymers and polymeric blends

Química Nova, 2005
Dynamic mechanical analysis (DMA) is widely used in materials characterization. In this work, we briefly introduce the main concepts related to this technique such as, linear and non-linear viscoelasticity, relaxation time, response of material when it ...

Thermoelastic Properties and Elastocaloric Effect in Rapidly Quenched Ribbons of Ti₂NiCu Alloy in the Amorphous and Crystalline State

Crystals, 2021
The thermoelastic properties and the elastocaloric effect (ECE) were studied in rapidly quenched ribbons of the Ti2NiCu alloy samples in amorphous and crystalline states under periodic mechanical tension with a frequency of up to 50 Hz.

Hematopoietic (stem) cells—The elixir of life?

FEBS Letters, EarlyView.
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

Study on Fracture Behavior of Directly Covered Thick Hard Roof Based on Bearing Capacity of Supports

Applied Sciences, 2023
Mine pressure at the working face is severe due to it being directly covered by a thick hard roof. To further investigate the technology of controlling the mine pressure of a thick hard roof, the upper working face of 13,121 in Gubei mine of Huainan ...

Hierarchical nanomechanics of collagen microfibrils [PDF]

, 2010
Collagen constitutes one third of the human proteome, providing mechanical stability, elasticity and strength to connective tissues. Collagen is also the dominating material in the extracellular matrix (ECM) and is thus crucial for cell differentiation ...

The role and implications of mammalian cellular circadian entrainment

FEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our
