compute these chemical features, a strategy that requires fine-tuning a considerable number of hyperparameters. Contrarily to these hand-crafted descriptors, end-to-end models learn the atomistic representations directly from more tangible physical variables (e.g.,R,Z). One of these is SchNet50,51...
whereMandz, related to specific materials, represent the molar mass of the substance in grams per mol and the valence number of ions of the substance (individual electric charges transferred per ion), respectively. In addition,Fis known as the Faraday constant with a fixed value of 96,485.3 ...
Herein, a sensitive fluorescence nanosensor was constructed based on NaYF4: Yb, Tm@NaYF4 upconversion nanoparticles (UCNPs) as fluorescent probe and 3-aminophenol (3-Aph) as the recognition element for NO–2 detection. The principle relied on the azoic compounds (AZO) formation by NO–2 ...
element-specific determinations such as electron densities (redox states) and high-precision spatial resolution determination of atoms in lattices from which hydrogen bonding, chemical bonding or van der Waals stacks can be derived. In less-ordered and disordered systems, X-rays deliver element-...
(A) Number of MOFs in the QMOF database containing a given element. All elements that occur in greater than 800 structures are capped at 800 for ease of visualization. These include: C (15,713), H (15,713), N (12,892), O (12,821), Cu (2,882), S (2,684), Zn (2,665)...

Indeed, according to Moro and Basile [169], this element is the most important active principle of this species since it has an active role in the production of thyroid hormones which in turn are responsible for the increase of the metabolism in most tissues, and the consequent raise of the...
Atomic number The atomic number of an element, Z, is equal to the number of protons that defines the element. For example, all carbon atoms contain 6 protons in their nucleus; so the atomic number "Z" of carbon is 6. Carbon atoms may have different numbers of neutrons, which are known...
