Propriedades relacionadas à acidez e basicidade a partir da abordagem em química computacional
Química Nova, 2014 Analytical Chemistry books lack a clear link between thermodynamic and equilibrium approaches involving acids and bases. In this work, theoretical calculations were performed to search for these relations.

Calculation of the static and dynamical correlation energy of pseudo-one-dimensional beryllium systems via a many-body expansion [PDF]
, 2016 Low-dimensional beryllium systems constitute interesting case studies for the test of correlation methods because of the importance of both static and dynamical correlation in the formation of the bond.

Possible role of human ribonuclease dicer in the regulation of R loops
FEBS Open Bio, EarlyView.R loops play an important role in regulating key cellular processes such as replication, transcription, centromere stabilization, or control of telomere length. However, the unscheduled accumulation of R loops can cause many diseases, including cancer, and neurodegenerative or inflammatory disorders. Interestingly, accumulating data indicate a possible

On the Energetics of the HCO$^+$ + C $\to$ CH$^+$ + CO Reaction and Some Astrochemical Implications [PDF]
, 2017 We explore the energetics of the titular reaction, which current astrochemical databases consider open at typical dense molecular (i.e., dark) cloud conditions.

FEBS Open Bio, EarlyView.Cerebral organoids were employed as a novel model to explore the neurotoxicity of soman. Soman inhibited acetylcholinesterase activity, increased cell apoptosis and upregulated endoplasmic reticulum (ER) stress markers glucose‐regulated protein 78 (GRP78), activating transcription factor 6 (ATF6) and C/EBP homologous protein (CHOP).

Conformer-specific Infrared spectroscopy of cationic Criegee intermediates syn- and anti-CH3CHOO+
Nature CommunicationsCriegee intermediates are pivotal in atmospheric chemistry, yet their cationic forms remain poorly understood. This study presents the infrared spectra of cationic Criegee intermediates, specifically syn- and anti-CH3CHOO+, using vacuum ultraviolet ...

Vibrational Branching Ratios From The Dissociation Of The NeIBr Van Der Waals Molecule [PDF]
, 1992 The degree of vibrational excitation in the IBr fragment from the vibrational predissociation of NeIBr (A (3)PI(1)) has been measured using two-color pump-probe laser-induced fluorescence spectroscopy.
