Labyrinthine Turing Pattern Formation in the Cerebral Cortex [PDF]

, 2002
I propose that the labyrinthine patterns of the cortices of mammalian brains may be formed by a Turing instability of interacting axonal guidance species acting together with the mechanical strain imposed by the interconnecting axons.Comment: See home ...

Generating active T1 transitions through mechanochemical feedback

eLife, 2023
Convergence–extension in embryos is controlled by chemical and mechanical signalling. A key cellular process is the exchange of neighbours via T1 transitions. We propose and analyse a model with positive feedback between recruitment of myosin motors and mechanical tension in cell junctions. The model produces active T1 events, which act to elongate the

A Polymer with Mechanochemically Active Hidden Length [PDF]

Journal of the American Chemical Society, 2020
Incorporating hidden length into polymer chains can improve their mechanical properties, because release of the hidden length under mechanical loads enables localized strain relief without chain fracture. To date, the design of hidden length has focused primarily on the choice of the sacrificial bonds holding the hidden length together.

X-ray structural analysis of the BaO and TiO2 starting compounds and initial mechanochemical activation [PDF]

Podzemni Radovi, 2023
The aim of this research was to obtain an initial characterization of the BaO and TiO2 components, as well as to conduct preliminary research into the possibility of activating the initial components in order to obtain barium titanate. Chemical and X-ray

Theoretical studies of a hydrogen abstraction tool for nanotechnology [PDF]

, 1991
In the design of a nanoscale, site-specific hydrogen abstraction tool, the authors suggest the use of an alkynyl radical tip. Using ab initio quantum-chemistry techniques including electron correlation they model the abstraction of hydrogen from ...

Prime movers : mechanochemistry of mitotic kinesins [PDF]

, 2014
Mitotic spindles are self-organizing protein machines that harness teams of multiple force generators to drive chromosome segregation. Kinesins are key members of these force-generating teams.

Leaching of gold from a mechanically and mechanochemically activated waste [PDF]

Acta Montanistica Slovaca, 2010
The intensification of leaching of gold from a waste using mechanical activation (milling in water) and mechanochemical activation(milling in thiourea solution) were studied as the pretreatment steps.

Kinetics of specific surface area change using the Boltzmann model [PDF]

Science of Sintering, 2009
During sintering of the 2MgO-2Al2O3-5SiO2 system, cordierite, an attractive ceramic material because of its properties, is obtained. Effects of mechanochemical activation of stoichiometric mixtures, performed to investigate possibilities of lowering ...

Mechanochemical synthesis of Pb2MgWO6 piezoceramics with alloying additives [PDF]

MATEC Web of Conferences, 2021
Pb2MgWO6 was prepared using mechanochemical activation and sintering in a temperature range of 600-1000ºÑ in three ways: 1) from oxides of the corresponding metals, 2) using MgWO4 precursor; and 3) in the presence of over-stoichiometric amounts (1wt ...
