PlumX: Highlights on the Binding of Cobalta‐Bis‐(Dicarbollide) with Glucose Units
Metalla‐bis‐dicarbollides, such as the cobalta‐bis‐dicarbollide (COSAN) anion [Co(C2B9H11)2], have attracted much attention in biology but a deep understanding of their interactions with cell components is still missing. For this purpose, we studied the interactions of COSAN with the glucose moiety, which is ubiquitous at biological interfaces.

PlumX: Resistive Switching Observation in a Gallium-Based Liquid Metal/Graphene Junction
Resistive switching effect is observed for a gallium–indium/gallium oxide/graphene junction. The use of a gallium-based liquid metal (LM) alloy, in this case, the eutectic gallium–indium with its native gallium oxide skin, directly provides the metal top contact and the oxide layer needed to fabricate a memory.

A photon reverses the binary 0/1 state of a memory device

Storing information with light

Press Links:
New photo-ferroelectric materials allow to store information in a non-volatile way using light stimulus. The idea is to create energy efficient memory devices with high performance and versatility to face the challenges of the current society.
 
The study has been publishd in Nature Communications by Josep Fontcuberta and co-workers and opens a path towards further investigations on this phenomenon and to neuromorphic computing applications.

Welcome Marc Domingo Cabasés at ICMAB!

Nombre y apellidos: Marc Domingo Cabasés

Hello everyone! My name is Marc and I have just joined, as a Ph.D. student, the Soft Matter Theory group. I will be developing computational models capable of predicting the interaction of encapsulated viruses (in particular, SARS-CoV-2) with materials, including textile surfaces and fibers. I am sure I will have an amazing time at ICMAB. I love doing sports, hiking, and being in contact with nature.

Computer simulations of the interaction between SARS-CoV-2 spike glycoprotein and different surfaces

Autores: David C. Malaspina and Jordi Faraudo
Citation: Biointerphases 15, 051008 (2020)
DOI: https://doi.org/10.1116/6.0000502
PlumX: Computer simulations of the interaction between SARS-CoV-2 spike glycoprotein and different surfaces
A prominent feature of coronaviruses is the presence of a large glycoprotein spike protruding from a lipidic membrane. This glycoprotein spike determines the interaction of coronaviruses with the environment and the host. In this paper, we perform all atomic molecular dynamics simulations of the interaction between the SARS-CoV-2 trimeric glycoprotein spike and surfaces of materials.

PlumX: Beating the Thermal Conductivity Alloy Limit Using Long-Period Compositionally Graded Si1–xGex Superlattices
Superlattices with scattering mechanisms at multiple length scales efficiently scatter phonons at all relevant wavelengths and provide a convenient route to reduce thermal transport. Here, we show, both experimentally and by atomistic simulations, that SiGe superlattices with well-established compositional gradients and a sufficient number of interfaces exhibit extremely low thermal conductivity.

Finding alternatives to gadolinium (Gd)-based contrast agents (CA) with the same or even better paramagnetic properties is crucial to overcome their established toxicity. Herein we describe the synthesis and characterization of entirely organic metal-free paramagnetic macromolecules based on biocompatible oligoethylene glycol dendrimers fully functionalized with 5 and 20 organic radicals (OEG Gn-PROXYL (n = 0, 1) radical dendrimers) with the aim to be used as magnetic resonance imaging (MRI) contrast agents.

PlumX: Homoconjugation in Light-Emitting Poly(phenylene methylene)s: Origin and Pressure-Enhanced Photoluminescence
The surprising optical properties of the non-π-conjugated polymer poly(phenylene methylene) (PPM) and its derivatives—that is, absorption in the 350–450 nm and photoluminescence (PL) in the 400–600 nm spectral regions—have been attributed to chromophores formed by homoconjugation along the polymer chain. The enabling role of homoconjugation, however, was hitherto ascertained primarily by excluding alternative origins of luminescence.

Probing nanoscale electrical properties of organic semiconducting materials at the interface with an electrolyte solution under externally applied voltages is key in the field of organic bioelectronics. It is demonstrated that the conductivity and interfacial capacitance of the active channel of an electrolyte‐gated organic field‐effect transistor (EGOFET) under operation can be probed at the nanoscale using scanning dielectric microscopy in force detection mode in liquid environment.

Experiences of "A researcher in your classroom 2.0" - online school visits

Even if we cannot go to schools face-to-face, ICMAB researchers have "visited" some schools using online platforms during these last months. For us it is important to still go to schools, to knock down the walls between young students and scientists, "for most of them it is the first time they meet someone who works as a researcher" says Judit Morlà Folch, one of the researchers who has participated.
