Carbon···Carbon Weak Interactions
The Journal of Physical Chemistry A, 2009 A theoretical study of the complexes formed by systems with electron-deficient and electron-excessive carbon atoms was carried out using DFT and ab initio methods up to the CCSD(T)/aug-cc-pVTZ computational level. Stable complexes with interaction energies between -6.0 and -22.8 kJ mol(-1) were obtained that correspond to weak C...C interactions.

A carbon–carbon hybrid – immobilizing carbon nanodots onto carbon nanotubes
Chemical Science, 2015 The thrust of this work is to integrate small and uniformly sized carbon nanodots (CNDs) with single-walled carbon nanotubes of different diameters as electron acceptors and electron donors, respectively, and to test their synergetic interactions in terms of optoelectronic devices.

Carbonation and Corrosion Problems in Reinforced Concrete Structures
Buildings, 2022 Reinforced concrete (RC) has been commonly used as a construction material for decades due to its high compressive strength and moderate tensile strength. However, these two properties of RC are frequently hampered by degradation.
