Article Synopsis
  • To achieve carbon neutrality by 2050, capturing carbon dioxide from the atmosphere is essential, and direct air capture (DAC) using amine-based compounds is being researched for effectiveness.
  • Researchers developed thermosetting DAC nanofibers that show strong performance with low-temperature desorption and heat resistance by polymerizing amines with epoxy, using poly(vinyl alcohol) (PVA) for easier fabrication.
  • The resulting nanofiber webs demonstrated high CO adsorption capacity and efficient desorption, allowing for sustainable and low-energy recovery of CO while also maintaining stability over prolonged use.

Stable planar dithienoarsinines were synthesized and structurally characterized. These compounds exhibit monomeric structures in the solution and solid states, avoiding dimerization, even in the absence of steric protection. They exhibited high global aromaticity with 14 or 22π-electron systems.

Background: Pulmonary arterial hypertension (PAH) is a severe complication among adult patients with congenital heart disease (ACHD). This study presents real-world data on risk stratification, pharmacotherapy and survival rates in PAH-ACHD.

Methods: Data from PAH-ACHD patients were analyzed using The Hellenic Pulmonary Hypertension Registry (HOPE), spanning eight specialized centers between 2015 and 2023.

The aggregation state of polyhedral oligomeric silsesquioxane (POSS) within a polymer matrix plays a crucial role. Molecular interactions are key driving forces for aggregation, and one of the key physical parameters is the dipole moment (DPM). Quantum calculations such as density functional theory (DFT) calculations can be used to estimate the DPM.
