Concentration limits for domoic acid (DA) in seafood are crucial for public safety due to potential health risks. The aim of this work is to develop and conduct a comprehensive analysis of a biosensor for detecting DA by using screen-printed carbon electrodes with gold nanoparticles. Additionally...
because of this reactivity the metal has found use in the manufacture of light bulbs and vacuum tubes as a scavenger for small amounts of oxygen and nitrogen. Hafnium reacts directly with the halogens to form tetrahalides, and when heated it reacts with carbon, boron, sulfur, and silicon....
it had to bemeaningful. Adding the number of spheres in the first, second and third layer of spheres around a nucleus sphere (12 + 42 + 92) yields 146 spheres. This is the number of neutrons in the element uranium. Add 92 to 146 to yield 238, the number...

Glucuronoyl esterases (GEs) are α/β serine hydrolases and a relatively new addition in the toolbox to reduce the recalcitrance of lignocellulose, the biggest obstacle in cost-effective utilization of this important renewable resource. While biochemical and structural characterization of GEs have prog...

The environment within the nucleus of a singleatomseems similar, with protons and neutrons also dancing about. But because the nucleus is such a compact space, scientists have struggled to pin down the behavior of these particles, known as nucleons, in an atom’s nucleus...
(R= 0.9997; 0.999): the nucleus' radius - the number of the nucleons; the electrons' critical energy - the number of the protons; the nucleus' coupling energy - the mass number; the number of the neutrons - the nucleus' charge; the ionization potential of the atom - the nucleus' ...
** Graphite is used to slow neutrons in epithermal designs, and deteriorates in a high neutron flux environment. The rate of damage increases with temperature, which is a particular problem with MSRs at 700°C. In liquid-fuel MSR designs the fission products dissolve in the fuel salt and ar...
