Article Synopsis
- Metal-organic frameworks (MOFs) are important materials used in various applications like catalysis and gas storage, but their open metal sites often get blocked by solvent molecules, requiring activation to use them effectively.
- Traditional activation methods use high temperatures, which can damage the MOFs, but a new 'gas-flow activation' technique employing inert gases at lower temperatures preserves their structure while effectively removing these solvent molecules.
- This study shows that this method not only works well with a specific MOF (HKUST-1) but is also applicable to other types, offering a safer, more efficient approach for activating MOFs without compromising their integrity.
Article Synopsis
- Researchers are addressing the challenge of protecting dopamine from oxidation by using SU-101 BioMOF as a host material.
- They explored different ways dopamine can be adsorbed into the SU-101 structure using a strong computational method.
- The findings indicate that encapsulating dopamine is possible, supported by experimental evidence showing non-covalent interactions within the SU-101 pores.
Background: Capacitive-resistive electric transfer (CRET) is a non-invasive therapeutic strategy that applies radiofrequency electric currents within the 400-600 kHz range to tissue repair and regeneration. Previous studies by our group have shown that 48 h of intermittent exposure to a 570 kHz CRET signal at a subthermal density of 50 μA/mm causes significant changes in the expression and activation of cell cycle control proteins, leading to cycle arrest in human cancer cell cultures. The present study investigates the relevance of the signal frequency in the response of the human neuroblastoma cell line NB69 to subthermal electric treatment with four different signal frequency currents within the 350-650 kHz range.
