A Two‐Dimensional Supramolecular Framework Created by Cooperative Self‐Assembly

open access: yesSmall Structures
A 2D van der Waals supramolecular framework is created by self‐assembled crystallization of C70 and decanethiol molecules on the Au(111) surface. This framework consists of C70 dimer rows with decanethiol molecules filling the space between the dimer ...

Designing Tailored Molecular Cavities Using Calix[5]arenes as Building Blocks

open access: yesThe Chemical Record, EarlyView.
This account focuses on the shape and dimensions of cavities formed by precisely designed molecular frameworks. It highlights our efforts to construct synthetically tailored cavities based on calix[5]arenes. This study examines the shapes and dimensions of cavities defined by well‐designed molecular structures.

Game-theory behaviour of large language models: The case of Keynesian beauty contests

open access: yesEconomics and Business Review
The growing adoption of large language models (LLMs) presents potential for deeper understanding of human behaviours within game theory frameworks. This paper examines strategic interactions among multiple types of LLM-based agents in a classical beauty ...

DFT study of interaction of acetylene and C70 fullerene molecules

open access: yesChemical Physics Impact
The interaction between the C70 fullerene and acetylene was investigated using DFT calculations (DFT/B3LYP/6–31G (d, p)). It is shown that the C72H2 formation proceeds through sequential [2 + 1], [2 + 2], and [3 + 2] cycloaddition reactions.

Value creation and value capture from patents: Theory and implications for patent strategies

open access: yesJournal of Innovation & Knowledge, 2023
This study uses biform game models to examine firms’ patent deployment strategies that involve a choice between appropriating a patented technology to gain a unique competitive advantage or licensing the technology to a competitor in the product market ...

Reversible Pressure-Induced Amorphization in Solid C70 : Raman and Photoluminescence Study

open access: yes, 1994
We have studied single crystals of $C_{70}$ by Raman scattering and photoluminescence in the pressure range from 0 to 31.1 GPa. The Raman spectrum at 31.1 GPa shows only a broad band similar to that of the amorphous carbon without any trace of the Raman ...

How Large, Decayed, and Moist Must Rotting Logs Be to Act as Thermally Buffered Microhabitats in Temperate Eastern United States Forests?

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
This study addresses the ecological role of coarse woody debris (CWD) as a thermally buffered microhabitat for saproxylic organisms in temperate eastern US forests. We measured internal and external log temperatures across four seasons in Southern Appalachian forests to test how log diameter, decay stage, and moisture influence thermal buffering.

Fusion mechanism in fullerene-fullerene collisions -- The deciding role of giant oblate-prolate motion

open access: yes, 2015
We provide answers to long-lasting questions in the puzzling behavior of fullerene-fullerene fusion: Why are the fusion barriers so exceptionally high and the fusion cross sections so extremely small? An ab initio nonadiabatic quantum molecular dynamics (
