Careless handling of tungsten carbide bricks around a 6.2 kg plutonium sphere resulted in a fatal dose of radiation at Los Alamos on August 21 , 1945 when scientist Harry K. Daghlian, Jr. received a dose estimated to be 5.1 sievert (510 rems) and died 25 days later.
The ensemble of colliding particles leads to the superposition of many Newton spheres, resulting in a blurring of the image.
The inverse opals prepared from the core-shell spheres have smaller air spheres and higher filling fraction than those with connective air spheres, resulting in a stronger structure.
An appropriate weighting scheme summarizes the number of atoms in the different spheres, resulting in a characteristic property of the atom.
Applying an insufficient attenuation correction, such as the MR-based AC, leads to less counts being detected from inside the non-radioactive spheres resulting in a higher contrast recovery value than when using CT-based AC.
The precipitated brushite crystals interlocked with one another and bridged the α-TCP spheres, resulting in a 10 min setting reaction at 37 °C that produced fully interconnected macroporous calcium phosphate.
On the other hand, for the phantom experiments the wall of the spheres, resulting in a shell of 'zero' activity around the spheres, may have affected performance evaluation [ 22].
While Stanković et al. [125] varied the pH value of the starting reaction solution from 8 to 12 that enabled in changing the morphology from micro-rods to nano-spheres, resulting in an efficient bacteriostatic activity.
As the temperature of a block copolymer solution is raised, the PPO block progressively loses its hydration sphere, resulting in greater interactions between the PPO blocks.
Therefore, the interface recombination between photoelectrode and electrolyte within DSSC would be retarded with this nitrogen-doped TiO2 sphere, resulting in the decrease of dark current and the improvement of J sc and V oc.
