Atoms are so small that we cannot see them with our eyes (i.e., microscopic). To give you a feel for some sizes, these are approximate diameters of various atoms and particles: atom = 1 x 10-10meters nucleus = 1 x 10-15to 1 x 10-14meters ...
or transit, their host stars. The planets cannot be seen directly but when they pass in front of their stars as seen from our point of view on Earth, telescopes can look for absorption of starlight by atoms in the planets’ atmospheres. In the case of the mini-...
Chemprop is a popular directed message-passing neural network (D-MPNN), a type of GNN that works on the features of directed edges (bonds) rather than atoms68,69. Chemprop has been applied to new antibiotic discovery by training models on bacterial growth inhibition datasets and subsequently pre...
To distinguish between nitrite ion (NO2-) and nitrate ion (NO3-), we can follow these steps:Step 1: Understanding the Ions - Nitrite Ion (NO2-): This ion has one nitrogen atom bonded to two oxygen atoms. - <str
The first fruits are already being picked. Take ammonia, a molecule made of nitrogen and hydrogen atoms that is a crucial part of fertiliser. We used about 166 million tonnes of it in 2016. Yet we still make it using the energy-intensive and 100-year-oldHaber process, which ...
Its strong basicity was attributed to the presence of the electron-rich stoppers that, due to their steric hindrance, force the lone pairs of the crown ether oxygen atoms and that of the secondary amine nitrogen atom of the axle to stay in close proximity, hugely destabilizing the rotaxane ...
In the latter type, if the atoms of the nanocatalyst appear in the products, the nanoparticle is no longer a catalyst but a reactant. In this review we attempt to answer the question raised in the title by examining our previous work on the changes in size, shape, and other physical ...
As researchers are considering a molecule, there are many tweaks they might want to test. Attaching a pair of hydrogen atoms instead of nitrogen atoms, for example, might make it easier for the body to take up the drug. Perhaps removing one carbon atom would reduce a particular side effect...
I found the atom type assignments are incorrect for some atoms in the MOL2 file: The atom types for most carbon atoms in ZINC000001644610 should be C.ar, representing aromatic carbons. The compound is correctly aromatized in the generated pdbqt file, probably because the bond section specifies...
In Ref.15, it is proposed from nuclear physics that neutrinos and anti-neutrino pair at low energies can be formed during inelastic collisions of particles (electrons, ions, neutral atoms) during their thermal motion. Temperatures known to be produced in cavitation processes may exceed the calculat...
