Synthesis of Cyclo[18]carbon via Debromination of …

Cyclo[18]carbon (C18, a molecular carbon allotrope) can be synthesized by dehalogenation of a bromocyclocarbon precursor, C18Br6, in 64% yield, by atomic manipulation on a sodium chloride bilayer on Cu(111) at 5 K, and imaged by high-resolution atomic force microscopy. This method of generating C18 gives a higher yield than that reported previously from the cyclocarbon oxide C24O6. The

Organometallic Chemistry | Max-Planck-Institut für …

Compounds, wherein a carbon atom configures all four valence electrons in form of two lone-pairs may seem elusive at first sight. Following insightful early reports and recent computational studies, however, our group is investigating the preparation and reactivity of compounds, in which carbon serves as the central atom of a complex.

Tuning in to AFM | Research | Chemistry World

Ernst Meyer and his colleagues from the University of Basel have bonded a single xenon atom, rather than a carbon monoxide molecule, to an AFM tip. By attaching a xenon, argon or krypton atom to a metal–organic framework and bringing the tip within close proximity, the team can measure the attractive force between the two noble atoms.

Carbon Nanotubes: A Review on Structure and Their …

Carbon nanotubes (CNTs) are allotropes of carbon with a nanostructure that can have a length-to-diameter ratio greater than 1,000,000. Techniques have been developed to produce nanotubes in sizeable quantities, including arc discharge, laser ablation, and chemical vapor deposition. Developments in the past few years have illustrated the potentially revolutionizing impact of nanomaterials

A Fast Soluble Carbon-Free Molecular Water Oxidation …

Increasing pH from the initial value of 7.5 to 8.0 (sodium phosphate buffer, NaPi) decreased the reaction time from 270 s to 90 s (respective final pH values after reaction are 7.3 and 7.5). The reaction was faster still in a solution with a higher buffer capacity at pH = 8.0 (a mixture of 30 mM NaPi and 30 mM sodium borate buffer; final pH > 7.9).
