-AlOOH) and gamma-alumina (-Al
O
) nanosheets with unique hierarchical multilayered structures is demonstrated. The nature and concentration of the biomolecules strongly influence the degree of the crystallinity, the morphology, and the textural properties of the resulting -AlOOH and -AlO nanosheets, allowing for easy tuning. The hierarchical -AlOOH and -AlO multilayered nanosheets synthesized by using biomolecules exhibit enhanced crystallinity, improved particle separation, and well-defined multilayered structures compared to those obtained without biomolecules. More impressively, these -AlOOH and -AlO nanosheets possess high surface areas up to 425 and 371 m
/g, respectively, due to their mesoporous nature and hierarchical multilayered structure. When employed for molybdenum adsorption toward medical radioisotope production, the hierarchical -AlO multilayered nanosheets exhibit Mo adsorption capacities of 33.1
40.8mg-Mo/g.

He
) have been studied by quantum path integral molecular dynamics simulations with different cluster sizes, 
= 18-200. The nuclear quantum effect of helium atoms plays an important role in the vibrational amplitude of the Ac-He complex at low temperatures (1-3 K) where the complex is stable. We found that the coordination number of helium atoms comprising the first solvation shell can be as high as eighteen. In this case, the helium atoms are arranged in D
symmetry. The Ac-He
complex becomes more rigid as the cluster increases in sizes, implying that it becomes more stable. The simulation results are based on an accurate description of the Ac-He interaction using relativistic ab initio calculations.

1,2-disubstitutedbenzocyclobutene molecule, we unravel the mechanism of force-induced ring-opening. The expected conrotatory process of reactant leading to

product is only observed at very small forces, whereas disrotatory ring-opening yields , diene at larger forces, which is shown to be a concerted process.
