Why individual heptagonal rings are not stable on surfaces?

Graphene nanoribbons, GNRs, – narrow stripes of graphene – are predicted to exhibit attractive electronic properties for the fabrication of nanoscale electronic devices. This 1D material shows semiconducting properties that can be tuned by modifying its length, width, or topology border; but also, with the presence of defects in form…

SYNTHESIS OF LONG-CHAIN ALIPHATIC HYDROCARBONS USING A GAS-PHASE METAL-FREE APPROACH (NAT. COMM. 2021)

Nowadays, there is an urgent need for the development of sustainable processes to produce synthetic chemicals, including long-chain aliphatic hydrocarbons. Whereas current industrial processes make use of non-abundant metal catalysts and high temperatures and pressures, we have explored an alternative gas-phase synthesis using only atomic carbon and molecular hydrogen along…

INTERACTION OF ATOMIC SILICON AND MOLECULAR HYDROGEN IN THE ENVELOPE OF EVOLVED STARS (ASTROPHYS. J. 2021)

In the atmosphere of carbon-rich (C-rich) asymptotic giant branch stars (AGBs), silicon chemistry plays an important role as is revealed by the detection of silane (SiH4) and organosilicon compounds such as methyl silane (CH3SiH3) and sylil cyanide (SiH3CN). To deepen the understanding on the formation of silicon bearing molecules in…

INFRA-ICE: SIMULATING THE COSMIC DUST-ICE INTERACTION IN THE INTERSTELLAR MEDIUM (REV. SCI. INSTRUM. 2020)

  The last module of Stardust, INFRA-ICE, is ready! This module is dedicated to simulate the chemistry taking place in the densest regions of the interstellar medium, the so-called dense molecular clouds. As such, INFRA-ICE expands the capabilities of Stardust allowing for the complete journey of cosmic dust to be…

Surfaces open new routes: unexpected formation of m-PANI oligomers from p-aminophenol (ANGEW. CHEM. 2020)

Surfaces never fail to surprise. Once more, they have demonstrated that chemistry on 2D metallic surfaces behaves differently to that on solution (3D). We have shown that highly unspecific solution-based Michael addition transforms into highly selective when carried out on a Pt(111) surface. In this way, we are able to…
