Supercritical CO2 Sorption Within Polymers Used in Medical Devices and Their Packaging

open access: yesJournal of Applied Polymer Science, EarlyView.
In situ CO2 sorption monitoring ensured the establishment of thermodynamic equilibrium in polymers used for medical devices and their packaging. All the studied polymers, except PETG, exhibited similar kinetic profiles, allowing the quantification of CO2 sorption and the resulting polymer swelling under thermodynamic equilibrium conditions. For PETG, a

Metallocene Coordination to Neutral Alkaline Earth Metal Complexes

open access: yesChemistry – An Asian Journal, EarlyView.
Reactions between a series of geometrically constrained, Lewis acidic group 2 metal diamide complexes, and first row transition metal metallocenes have given a range of adducts in which the metallocene coordinates to the group 2 metal center through one of its cyclopentadienyl rings.

Early Cycle Life Prediction of Lithium‐Metal Batteries with the Aid of Machine Learning

open access: yesBatteries &Supercaps, EarlyView.
A machine learning model predicts the cycle life of lithium‐metal batteries using features extracted from first‐cycle charge–discharge data and impedance spectroscopy. Trained on 43 cells with varied chemistries and formation protocols, the model achieved up to 9.6% error, demonstrating a fast, cost‐effective approach to early battery life prediction ...

Programmatic regulation of macrophage polarization by HAp@MXene nanocomposites to promote bone repair

open access: yesBMEMat, EarlyView.
HAp@MXene nanocomposites could achieve the programmed regulation of macrophage polarization. They first induce M1 polarization through magnetoelectric induction to combat infection. Subsequently, controlled Ca2+ release drives M2 polarization to promote tissue regeneration. This dual mechanism accelerates bone defect repair and highlights the potential
