Like a human language, the SMILES syntax imposes strict rules on which strings are syntactically valid. This means that chemical language models can generate SMILES that do not correspond to any valid chemical structure (Fig.1b). The generation of invalid SMILES is widely perceived to be an imp...
Its chemical structure is similar to caffeine, but the pharmacological effect is slightly weaker than caffeine. It has good solubility in water, hot water, alkali hydroxide solution, ammonia water, dilute hydrochloric acid, and dilute nitric acid, and is slightly soluble in ether. These chemica...
Then we outline the design goals of InChI and our gen- eral approach, focussing on the InChI model of chemical structure and the hierarchical layered structure of the Identifier; the concept of Standard InChI is introduced. This is followed by a detailed description of each of the possible ...
To enhance the aforementioned characteristics, bismuth ferrite (BFO) was added to a Nafion matrix, resulting in a porous structure that increases capacitance. Moreover, the BFO-Nafion nanocomposite membrane exhibits a notably higher proton conductivity (0.1806 Scm− 1) at a temperature of 30° C...
