Ni(II) complexes with an integer spin = 1 that behave as clock transition spin qubits at zero magnetic field are resilient to magnetic fluctuations of the spin bath, while Co(II) complexes with a half-integer spin ( = 3/2) lose their coherence when they are subject to the same fluctuating magnetic field as the Ni(II) ones. These findings demonstrate that adequately designed Ni(II) complexes are excellent candidates for spin qubits.

Crystallography of quasiperiodic moiré patterns in homophase twisted bilayers.

Acta Crystallogr A Found Adv

March 2025

CNRS UMR 8247, Institut de Recherche de Chimie ParisTech, 11 rue Pierre et Marie Curie, 75005 Paris, France.

This paper discusses the geometric properties and symmetries of general moiré patterns generated by homophase bilayers twisted by rotation 2δ. These patterns are generically quasiperiodic of rank 4 and result from the interferences between two basic periodicities incommensurate to each other, defined by the sites in the layers that are kept invariant through the symmetry operations of the structure. These invariant sites are distributed on the nodes of a set of lattices called Φ-lattices - where Φ runs on the rotation operations of the symmetry group of the monolayers - which are the centers of rotation 2δ + Φ transforming a lattice node of the first layer into a node of the second.

Biological vision systems simultaneously learn to efficiently encode their visual inputs and to control the movements of their eyes based on the visual input they sample. This autonomous joint learning of visual representations and actions has previously been modeled in the Active Efficient Coding (AEC) framework and implemented using traditional frame-based cameras. However, modern event-based cameras are inspired by the retina and offer advantages in terms of acquisition rate, dynamic range, and power consumption.

Supramolecular oleogels, in which low-molecular weight oleogelators self-assemble into various nanostructures through non-covalent interactions, have witnessed increasing research activity in various fields of science, including food, cosmetics or remediation of marine oil spills. Herein, we report a simple scalable and environmentally friendly carbohydrate-based oleogelator, namely, the sodium salt of ,'-dimethyl β- glucosyl barbiturate (GlcBMe) that self-assembles through sonication to induce the gelation of polar organic solvent and later of non-polar vegetable oils by cationic exchange with quaternary ammonium surfactants. Water-soluble GlcBMe was capable of forming self-assembled fibrillar network bridging insoluble particles in the oil by sonication in the presence of a small amount of water.

Introduction: The neuron-specific K-Cl cotransporter KCC2 maintains low intracellular chloride levels, which are crucial for fast GABAergic and glycinergic neurotransmission. KCC2 also plays a pivotal role in the development of excitatory glutamatergic neurotransmission by promoting dendritic spine maturation. The cytoplasmic C-terminal domain (KCC2-CTD) plays a critical regulatory role in the molecular mechanisms controlling the cotransporter activity through dimerization, phosphorylation, and protein interaction.
