The molecular formula for water is written as {eq}H_{2}O {/eq}, where the number two is written as a subscript that represents that a water molecule is composed of two hydrogen atoms, as mentioned earlier in this lesson. Refer to the image for the molecular formula for the chemical ...
The chemical formula of Barium sulfate is BaSO4, where Ba represents the element barium and SO4 represents the sulfate ion. Barium sulfate is an inorganic compound with high stability and chemical inertness. It can be prepared by reacting barium salts with sulfuric acid or sulfate salts. The mol...

The signal intensity of one single pixel plotted as a function of the wavelength (z) dimension represents a standard spectrum (one is shown in the figure). It is the wavelength dimension that visualises chemical specificity by segregating different chemical species to different spectral regions of ...
06. Shaded area in (c) and (d) represents the time when neural clips were played. Full size image Discussion The results presented above show that the overall experimental procedure was successful. The films elicited various degrees of arousal response in the participants that could be monitored...
New 2-piperazino-pteridines of general formula <IMAGE> are described wherein R1 represents a phenylalkylamino, alkylamino or dialkylamino group, a piperidino, morpholino, thiomorpholino, or 1-oxidothiomorpholino group, R2 represents a dialkylamino, piperidino, morpholino, thiomorpholino or 1-oxidoth...
lifetime of the excited state of the fluorescent species (i.e., the average time during which these species stay in the excited state). However, interactions of a fluorescent species with its micro-environment often perturb the fluorescence decay so that information on this micro-environment can...
Dopamine (DA) is one of the most important neurotransmitters. Its oxidation leads to electrophilic quinone, which covalently modifies nucleophilic residues in proteins, resulting in ‘dopamination’. Individual dopaminated proteins have been studied, mos
Linear notation and connection tables are two systems that enable an efficient coding of molecular graphs. Linear notation is a system that allows a molecule to be represented in the form of a string similar to that of line formulae. The Dyson, Wiswesser (WNL), Sybyl, Representation of ...
106,107,108,109, but one needs to be prepared for no generalist simple model achieving sufficient overall accuracy close to that of DFT. For this reason, we proposed a different scheme, called life-long machine learning potentials that can adjust in an exploration in a system-focused fashion...
