Analyzing the interactions between 2-ethylhexyl 4-methoxycinnamate and bovine serum albumin under coexistence and encapsulation of β-cyclodextrin.

2-ethylhexyl 4-methoxycinnamate (EHMC), a UV filter commonly used in sunscreen products, is also an emerging environmental pollutant that interferes with the structure and function of bovine serum albumin (BSA). A study was conducted on the interaction between EHMC and BSA when they coexist and are encapsulated within β-cyclodextrin (β-CD). Multiple spectra demonstrate, both qualitatively and quantitatively, that β-CD coexistence and encapsulation weaken the interaction between EHMC and BSA, resulting in a more difficult binding process between the two and inhibiting EHMC-induced conformational changes in BSA.

Coherent Strain-Inhibiting Phase Construction of Lithium-Rich Manganese-Based Oxide Toward High Mechanochemical Stability.

A layered lithium-rich manganese-based oxide cathode, containing 3̅ (LiTMO, TM = Mn, Ni, Co) and 2/ (LiMnO) nanodomains, utilizes both transition metals and oxygen redox to yield substantial energy density. However, the inherent heterogeneous nature and distinct nanodomain redox chemistries of layered lithium-rich oxides will inevitably cause pernicious lattice strain and structural displacement, which can hardly be eliminated by conventional doping or coating strategies and result in accelerated performance decay. Herein, we incorporate a strain-inhibiting perovskite phase coherently grown within the layered structure to effectively restrain the displacement and lattice strain during uneven Li-ion extraction.
