Iron (atomic symbol: Fe, atomic number: 26) is a Block D, Group 8, Period 4 element with an atomic weight of 55.845. The number of electrons in each of Iron's shells is 2, 8, 14, 2 and its electron configuration is [Ar] 3d6 4s2. The iron atom has a radius of 126 pm and...
The average hydrodynamic radius of the particles is found around 215 nm, which indicates aggregation rather than a dispersion of individual particles despite the high surface charge, which should prevent aggregation. Imaging the transferred particles in STEM reveals that their size is unchanged by ...
The excitation wavelength was set to 483 nm and the emission wavelength to 500 nm for SYTO9 detection, with image stacks acquired using a 10X objective lens. Image analysis was performed using COMSTAT2 software to quantify bio-volume (biomass volume divided by substrate area; μm3μm-2)...

This iron(II) has the potential to be transported by the CaV1.3 channel, as its atomic radius (ionic radius: 0.92 Å) is significantly less than that of calcium(II) (ionic radius: 1.14 Å) [39]. Of interest, non-transferrin-bound iron(II) has been demonstrated to permeate the CaV...
However, due to the ionic radius of Fe3+ ions (0.065 nm) compared to Ca2+ ions (0.100 nm), a decrease in cell parameters was expected. This opposite experimental result was explained by Shi et al. [44] by a charge balancing process that occurred in the system. It is assumed that ...
atomic vacancies33, and magnetic adatoms34,35. While the vortex Majorana signals in tFeSCs are usually believed to arise from the Fu-Kane mechanism36,37,38, origins of the vacancy/impurity-related zero-bias peaks are still under debate39,40,41,42,43,44. Noting that vacancies and add-on ...
