The rapid advancements in 3C electronic devices necessitate an increase in the charge cutoff voltage of LiCoO to unlock a higher energy density that surpasses the currently available levels. However, the structural devastation and electrochemical decay of LiCoO are significantly exacerbated, particularly at ≥4.5 V, due to the stress concentration caused by more severe lattice expansion and shrinkage, coupled with heterogeneous Li intercalation/deintercalation reactions.

The theory of periodic Barlow multi-lattices (X1X2…XN)∞ with Xi ∈ {A, B, C} and Xi ≠ Xi+1 of stacked two-dimensional hexagonal close-packed layers is presented and used to derive exact lattice sum expressions in terms of fast converging Bessel function expansions for inverse power potentials. We describe in detail the mathematical properties of Barlow sphere packings and demonstrate that only two basic lattice sums are required to describe all periodic packings. For the sticky hard-sphere model with an attractive inverse power law potential, we find a linear correlation between the cohesive energies of different Barlow packings and the face-centered cubic packing fraction.

Substitution metal doping strategies are crucial for developing catalysts capable of activating O, but the leaching of metal dopants has greatly hindered their potential for extensive oxidation reactions under mild conditions. Here, the study develops an entropy-increase strategy to synthesize high-entropy metal (Mg, Ca, Mn, Fe, and Co) interstitial functionalized anatase TiO (HE-TiO) nanosheets, demonstrating remarkable degradation efficiency across a wide pH range and exceptional stability in a flow-by electro-catalytic reactor. Relative to that of pristine TiO, the intense lattice distortion on the (001) plane, an average lattice expansion of 2% on the (100) plane, and decrease of second shell peak of X-ray absorption spectra serve as compelling evidence for the formation of metal interstitials in HE-TiO.

Microtubule (MT) function plasticity originates from its composition of α- and β-tubulin isotypes and the post-translational modifications of both subunits. Aspects such as MT assembly dynamics, structure, and anticancer drug binding can be modulated by αβ-tubulin heterogeneity. However, the exact molecular mechanism regulating these aspects is only partially understood.

Electrically conducting 2D metal-organic frameworks (MOFs) with hexagonal 2D lattices like other 2D van der Waals stacked materials are attracting increasing interest. The conductivity can be effectively regulated through electronic structure adjustment thanks to the chemical and physical flexibility and adjustability of MOFs. In this regard, through a simple and rapid electrochemical method, 2D conductive iron-quinoid MOFs were synthesized.
