A generalized approach for NMR studies of lipid–protein interactions

A generalized approach for NMR studies of lipid–protein interactions

BiochemistryChemistryMolecular biology

By Invited Researcher

Author: Francisco J. Blanco is an Ikerbasque Research Professor at CIC bioGUNE Molecular interactions in cell membranes, particularly lipid-protein interactions in their hydrophobic core, are difficult to analyse and remain poorly characterised despite high relevance in physiological and pathological processes. Structural rearrangements in membranes and embedded proteins, and the way molecular interactions contribute to their […]

Surface-Enhanced Molecular Electron Energy Loss Spectroscopy

Condensed matterMaterialsNanotechnologyPhysicsQuantum physicsTheoretical physics

By DIPC

Chemists have a range of different spectroscopic techniques to study organic molecules. All of these techniques are based on spectra generated by a range of electronic transitions and vibrations, key excitations in matter, the study of which provides information about characteristics of materials and, therefore, allow their identification. In this context, one of those spectroscopic […]

High-performance supramolecular polymer from a simple molecule

High-performance supramolecular polymer from a simple molecule

Chemistry

By Pablo Ortiz

Turning simple, individual molecules into complex, interconnected materials is the core of polymer chemistry. There is currently an increasing demand for materials with sophisticated properties such as self-healing and reusable adhesivity. However, achieving polymers with such functionalities generally demands higher structural complexity, synthetic difficulty, and cost. Now, a team of chemists has designed a supramolecular […]

The properties of bismuth have long defied classification, placing it in a category of its own. Now, as if it was not enough, it turns out its electronic structure has higher-order topology. This has been shown by an international team with the participation of Maia G. Vergniory (DIPC, Ikerbasque, UPV/EHU) and coordinated by Titus Neupert […]

Differences in the reward pathway in autism

Differences in the reward pathway in autism

Neurobiology

By José Ramón Alonso

The reward pathway is a group of brain structures connected to each other that are key in the processes of motivation (desire, motivation, craving), associative learning (operant reinforcement and positive conditioning) and in positive emotions, particularly those in which pleasure has a fundamental component such as joy, euphoria and ecstasy. The reward is an attractive […]

The microscopic mechanism behind the vibrational relaxation of adsorbates on metal surfaces

The microscopic mechanism behind the vibrational relaxation of adsorbates on metal surfaces

Condensed matterMaterialsNanotechnologyPhysicsTheoretical physics

By DIPC

Most of the theories describing dynamical processes at surfaces rely on the validity of the adiabatic Born-Oppenheimer approximation. What does this mean? We have already seen that adsorption commonly is understood as the reversible binding of molecules and atoms from the gaseous or liquid phase on surfaces, mostly of highly porous adsorbent media. In chemisorption […]

Using machine learning to discover new metallic glasses

Using machine learning to discover new metallic glasses

Computer scienceCondensed matterMaterials

By Silvia Román

Metallic glasses are a unique class of materials whose properties combine some of the irreconcilable properties of both metals and polymers. They consist of a combination of metals which, in the solid state, present an amorphous atomic structure, in contrast to common metal alloys, which present a highly ordered microscopic pattern. This lack of crystalline […]

Author: Roberto D’Agosta is an Ikerbasque Research Professor at ETSF and the Department of Materials Physics in the Faculty of Chemistry at the UPV/EHU in San Sebastian. Francesca Baletto, senior lecturer at King’s College London, read and commented the manuscript. Every single moment, nature exploits catalysis to make or improve specific chemical reactions. Catalysts facilitate […]

Uropathogenic Escherichia coli (UPEC) is responsible for approximately 90% of urinary tract infections (UTI) seen in individuals with an ordinary anatomy. In ascending infections, fecal bacteria colonize the urethra and spread up the urinary tract to the bladder as well as to the kidneys (causing pyelonephritis), o or the prostate in males. Because women have […]
