Maintenance of Constant Wave Parameters by Sperm Flagella at Reduced Frequencies of Beat [PDF]
, 1973 1. Treatment of Ciona spermatozoa with low concentrations of Triton X-100 (less than 0·01 %) causes them to beat at lower than normal frequencies. The wavelength of the flagellar bending waves remains constant over the range from 10 to 40 Hz.

On the synthesis of 3-cyano-6-hydroxy-4-methyl-2-pyridone at room temperature
Zaštita Materijala, 2019 Milling of cyanoacetamide and acetoacetic ester as reactants, in the presence of KOH as the catalyst and ethanol as a viscous control agent (VCA) was performed in a planetary ball mill with the goal of investigating the effect of mechanochemical ...

The kinesin walk: a dynamic model with elastically coupled heads
, 1998 Recently individual two-headed kinesin molecules have been studied in in vitro motility assays revealing a number of their peculiar transport properties. In this paper we propose a simple and robust model for the kinesin stepping process with elastically

Magnetic Properties of Bismuth Ferrite Nanopowder Obtained by Mechanochemical Synthesis
, 2014 Multiferroic bismuth ferrite (BiFeO3) nanopowders have been obtained in room temperature by mechanical synthesis. Depending on the post-synthesis processing the nanopowders have exhibited differences in the mean sizes, presence of amorphous layer and/or ...

Mechanochemistry-assisted synthesis of hierarchical porous carbons applied as supercapacitors
Beilstein Journal of Organic Chemistry, 2017 A solvent-free synthesis of hierarchical porous carbons is conducted by a facile and fast mechanochemical reaction in a ball mill. By means of a mechanochemical ball-milling approach, we obtained titanium(IV) citrate-based polymers, which have been ...
