Ionic Bonds Control Ferroelectric Behavior in Wurtzite Nitrides [PDF]
arXiv, 2022 Ferroelectricity enables key integrated technologies from non-volatile memory to precision ultrasound. Wurtzite ferroelectric Al1-xScxN has recently attracted attention because of its robust ferroelectricity and Si process compatibility in addition to being the first known ferroelectric wurtzite.

Nature Communications, 2022 The properties of actinide complexes depend on the ionic versus covalent nature of the bonds. Here, the authors report that pressure can distort actinide-oxygen bonding; differences seen for Th, U and Np result from the decreasing size of the atoms.

Charge dynamics in the Mott insulating phase of the ionic Hubbard model [PDF]
Phys. Rev. B 69, 041101(R) (2004), 2003 We extend to charge and bond operators the transformation that maps the ionic Hubbard model at half filling onto an effective spin Hamiltonian. Using these operators we calculate the amplitude of the charge density wave in different dimensions. In one dimension, the charge-charge correlations at large distance d decay as 1/(d^3 ln^{3/2}d), in spite of ...

Oxygen Donor Stabilized Alkaline Earth Metal Iodides
CHIMIA, 2003 Alkaline earth metal iodides show ionic behavior in water, but their bonding situation is not that clear in less polar solvents. The alkaline earth metal iodide adducts, i.e. [MI2(thf)5](M = Sr and Ba), [CaI2(L)4] (L = thf, H2O), [Ba(OH)I(H2O)4]

Monovalent impurities on graphene: midgap states and migration barriers [PDF]
Phys. Rev. B 80, 085428 (2009), 2009 Monovalent impurities on graphene can be divided into ionically and covalently bond impurities. The covalent impurities cause universal midgap states as the carbon atom next to the impurity is effectively decoupled from the graphene pi-bands. The electronic structure of graphene suppresses migration of these impurities and making the universal midgap ...

Quantum Chemical Modeling of Hydrogen Bonding in Ionic Liquids
Topics in current chemistry, 2017 Hydrogen bonding (H-bonding) is an important and very general phenomenon. H-bonding is part of the basis of life in DNA, key in controlling the properties of water and ice, and critical to modern applications such as crystal engineering, catalysis ...

Revisiting the Nature of Chemical Bonding in Chalcogenides to Explain and Design their Properties
Advances in Materials, 2022 Quantum chemical bonding descriptors have recently been utilized to design materials with tailored properties. Their usage to facilitate a quantitative description of bonding in chalcogenides as well as the transition between different bonding mechanisms

FEBS Letters, EarlyView.Venom peptides have shown promise in treating pain. Our study uses computer screening to identify a peptide that targets a sodium channel (NaV1.7) linked to chronic pain. We produced the peptide in the laboratory and refined its design, advancing the search for innovative pain therapies.
