Conversion of gel-forming crystal needles to easily processable more equant crystals Using high-shear ultralow attrition agitation: accelerated Ostwald ripening without crystal attrition
(American Chemical Society, 2019-02-01)We demonstrate the first examples of the transformation of gel-forming crystal needles into easily processable more equant crystals by accelerated Ostwald ripening without detectable crystal attrition. Using high solution ... -
Effect of pre-corrosion on damage evolution and crack propagation in aluminum alloy 7050-T7651
(Wiley, 2018-05-16)This paper investigates the effects of pre-corrosion on the tensile behavior of aluminum alloy 7050-T7651. A combined experimental approach involving digital image correlation, scanning electron microscopy, and tensile ... -
GDNF Schwann cells in hydrogel scaffolds promote regional axon regeneration, remyelination and functional improvement after spinal cord transection in rats
(Wiley, 2017-03-10)Positively-charged oligo[poly(ethylene glycol)fumarate] (OPF+) is a biodegradable hydrogel used for spinal cord injury repair. We compared scaffolds containing primary Schwann cells (SCs) to scaffolds delivering SCs ... -
Identification of Components of the Sigma B Regulon in Listeria monocytogenes That Contribute to Acid and Salt Tolerance
(American Society for Microbiology, 2008-09)Sigma B is an alternative sigma factor that controls the transcriptional response to stress in Listeria monocytogenes and is also known to play a role in the virulence of this human pathogen. In the present study we ... -
Mesenchymal stem cells in the colorectal tumor microenvironment: Recent progress and implications
(Wiley, 2012-01-30)Mesenchymal stem cells (MSCs) are nonhematopoietic multipotent adult stem cells. They have been shown to have a natural tropism for many tumors types, including colorectal, and are capable of escaping host immune surveillance. ... -
Multi-sector approximation method for arteries: the residual stresses of circumferential rings with non-trivial openings
(The Royal Society, 2019-07-24)The opening angle method is a popular choice in biomechanics to estimate residual stresses in arteries. Experimentally, it means that an artery is cut into rings; then the rings are cut axially or radially allowing them ... -
Picking a way forward: valuing and managing traditional shellfish gathering for Littorina littorea
(EDP Sciences, 2018-11-27)Littorina littorea (periwinkles) have been harvested by hand picking from the shore since prehistoric times. Harvests are generally unregulated, catches are not linked to particular shores and fisheries statistics are ... -
Prescribing patterns in growing tubular soft matter by initial residual stress
(Royal Society of Chemistry, 2019-10-02)Initial residual stress is omnipresent in biological tissues and soft matter, and can affect growth-induced pattern selection significantly. Here we demonstrate this effect experimentally by letting soft tubes grow in the ... -
Sea-spray regulates sulfate cloud droplet activation over oceans
(Nature Research (part of Springer Nature), 2020-04-08)Sulfate aerosols are typically the dominant source of cloud condensation nuclei (CCN) over remote oceans and their abundance is thought to be the dominating factor in determining oceanic cloud brightness. Their activation ... -
A strain-gradient, crystal plasticity model for microstructure-sensitive fretting crack initiation in ferritic-pearlitic steel for flexible marine risers
(Elsevier, 2018-02-03)A three-dimensional, strain-gradient, crystal plasticity methodology is presented for prediction of microstructure-sensitive length-scale effects in crack initiation, under fatigue and fretting fatigue conditions, for a ...
