Photoinduced dynamics in protonated aromatic amino acid

open access: yes, 2008
UV photoinduced fragmentation of protonated aromatics amino acids have emerged the last few years, coming from a situation where nothing was known to what we think a good understanding of the optical properties.

Ammoxidation of Unprotected Glycosides: A One‐Pot Conversion of Alcohols to Nitriles

open access: yesChemistry – A European Journal, Volume 31, Issue 28, May 19, 2025.
Efficient C5‐selective ammoxidation of minimally protected carbohydrates enables direct access to nitrile sugars, valuable in bioorthogonal chemistry and drug development. Using TEMPO, PIDA, and ammonium acetate in aqueous acetonitrile, this method offers high selectivity without protecting groups.

Soliton molecules in Sharma-Tasso-Olver-Burgers equation [PDF]

open access: yesarXiv, 2019
Soliton molecules have been experimentally discovered in optics and theoretically investigated for coupled systems. This paper is concerned with the formation of soliton molecules by the resonant mechanism for a noncoupled system, the Sharma-Tasso-Olver-Burgers (STOB) equation.

Self‐consistent molecular orbital methods. XXIII. A polarization‐type basis set for second‐row elements [PDF]

open access: yes, 1982
The 6‐31G* and 6‐31G** basis sets previously introduced for first‐row atoms have been extended through the second‐row of the periodic table. Equilibrium geometries for one‐heavy‐atom hydrides calculated for the two‐basis sets and using Hartree–Fock wave ...

UniMoT: Unified Molecule-Text Language Model with Discrete Token Representation [PDF]

open access: yesarXiv
The remarkable success of Large Language Models (LLMs) across diverse tasks has driven the research community to extend their capabilities to molecular applications. However, most molecular LLMs employ adapter-based architectures that do not treat molecule and text modalities equally and lack a supervision signal for the molecule modality.

Diff4VS: HIV-inhibiting Molecules Generation with Classifier Guidance Diffusion for Virtual Screening [PDF]

open access: yesarXiv
The AIDS epidemic has killed 40 million people and caused serious global problems. The identification of new HIV-inhibiting molecules is of great importance for combating the AIDS epidemic. Here, the Classifier Guidance Diffusion model and ligand-based virtual screening strategy are combined to discover potential HIV-inhibiting molecules for the first ...
