UV-Induced Mechanism of Aliphatic Cleavage in the Interstellar Medium
In the interstellar medium (ISM), UV processing leads to significant chemical transformations in hydrocarbons. Aliphatic hydrocarbons such as alkanes, commonly formed in evolved stars, undergo dehydrogenation primarily through UV-induced photocleavage of C–C bonds rather than direct hydrogen elimination. This study combines experimental data and ab initio calculations to understand how…

One of the primary challenges associated with the use of titanium dioxide as a photocatalyst lies in its wide bandgap. In our research, we addressed this issue by employing a thermal treatment in atomic hydrogen plasma to reduce TiO2. This process led to an enhancement in the material’s light absorption…
Electron-stimulated desorption kinetics of ultra-thin LiCl films on graphene
Although ultra-thin alkali halide films are widely employed substrates due to their insulating behavior, their structural stability upon electron and photon beam exposure is not fully understood. In this study, we focus on the evolution of the LiCl thin film structure on graphene through low-energy electron irradiation. We observe desorption…
Unraveling the mechanisms of Thermal Dehydrogenation of n-Octane on Pt(111) at the atomic scale
In our article published recently in Nanoscale, we focus on the thermal dehydrogenation of n-octane (n-C8H18) on the catalytic Pt(111) surface in ultra-high vacuum. Our results shed light on the mechanisms behind the initial stages of this industrially relevant reaction, paving the way for the design of efficient dehydrogenation catalysts.…
Development of a Graphene SG-FET aptasensor able to detect attomolar concentrations of hepatitis C virus core protein
Biosensors based on graphene field-effect transistors have become a promising tool for detecting a broad range of analytes. However, they lack the stability and reproducibility required to step into biotechnological and biomedical applications. ESISNA group has used a promising physical graphene functionalization protocol which allows atomically-precise highly-controlled covalent functionalization, preserving…
The influence of reaction conditions on the growth of MOFs on surfaces
The importance of the reaction conditions has been confirmed in this study, where following an on-surface synthesis approach on the same surface and with the same precursor, two different metal-organic frameworks were obtained. The distinction comes from the different synthesis protocol of the controlled growth of both metal-organic nanostructures. Thus,…
Front cover in Chemistry – A European Journal!
Host-guest interactions are of paramount importance in supramolecular chemistry and in a wide range of applications. Particularly well known is the ability of cucurbit[n]urils (CB[n]) to selectively host small molecules. We show that the charge transfer and complexation capabilities of CB[n] are retained on the surface of 2D transition metal…
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…

PhotoSurf: ESISNA starts new research project side by side with FRONCAT
ESISNA, research group in Material Science, and FRONCAT, research group in Chemistry, will work together on PhotoSurf, a synergy I+D project of the Comunidad de Madrid. Both groups will join forces to mimic the photosynthesis process of plants and generate new materials using light. Project FOTOSURF-CM, ref. Y2020/NMT-6469
