TriplatinNC and Biomolecules: Building Models Based on Non-covalent Interactions

Frontiers in Chemistry, 2019
The class of polynuclear platinum(II) compounds have demonstrated a great interest because their high activity against cancer cells. Among these new compounds, the TriplatinNC also called AH78, demonstrated surprising antitumor activity, in some cases ...

Towards the construction of an accurate kinetic energy density functional and its functional derivative through physics-informed neural networks

Journal of Physics Communications, 2023
One of the primary obstacles in the development of orbital–free density functional theory is the lack of an accurate functional for the Kohn–Sham non-interacting kinetic energy, which, in addition to its accuracy, must also render a good approximation ...

The importance of the bite angle of metal(III) salen catalysts in the sequestration of CO2 with epoxides in mild conditions

Green Chemical Engineering, 2022
Located in the middle of the fever to solve the problem of CO2 emissions in the environment, CO2 sequestration by reaction with epoxides is one of the key tools, as it not only fixes CO2, but also makes it functional by leading to cyclic carbonates ...

The Coulomb Hole of the Ne atom

, 2019
We analyze the Coulomb hole of Ne from highly-accurate CISD wave functions obtained from optimized even-tempered basis sets. Using a two-fold extrapolation procedure we obtain highly accurate results that recover 97\% of the correlation energy.

Multiparameter Optimization of Trypanocidal Cruzain Inhibitors With In Vivo Activity and Favorable Pharmacokinetics

Frontiers in Pharmacology, 2022
Cruzain, the main cysteine protease of Trypanosoma cruzi, plays key roles in all stages of the parasite’s life cycle, including nutrition acquisition, differentiation, evasion of the host immune system, and invasion of host cells.

Aromaticity Determines the Relative Stability of Kinked vs. Straight Topologies in Polycyclic Aromatic Hydrocarbons

Frontiers in Chemistry, 2018
It is well-known that kinked phenacenes are more stable than their isomeric linear acenes, the archetypal example being phenanthrene that is more stable than anthracene by about 4–8 kcal/mol.

A Cu‐Based Near‐IR Active MOF with an Ion‐Pair Guest Exhibiting Versatile and Selective Gas‐Solid Reactivity

Advanced Materials, EarlyView.
The new Cu‐containing MOF (Me2NH2)(CuICl2)@[Cu4(INA)4Cl2O]·1.5dmf (3) contains a cation and an anion as guests and shows UV‐near‐mid‐IR absorption and near‐IR emission. MOF 3 shows gas‐solid reactivity in the presence of NH3 and HCOOH to yield two new 3D MOF.
