2D Multivariate‐Metal‐Organic Frameworks (2D‐M2OF) for High Yield Ammonia Synthesis from Nitrate

Advanced Energy Materials, EarlyView.
2D multivariate‐metal‐organic frameworks (2D‐M2OFs) enable efficient ammonia electrosynthesis from nitrates under ambient conditions. Incorporating Co, Ni, Mn, and Ag into BHT‐based 2D‐MOF creates a synergistic catalytic architecture that enhances nitrate reduction via surface hydrogen co‐adsorption.

Effect of Propagating Dopant Reactivity on Lattice Oxygen Loss in LLZO Solid Electrolyte Contacted with Lithium Metal

Advanced Energy Materials, EarlyView.
The decomposition of Nb‐substituted LLZO solid electrolytes is reported through a propagating reaction between Nb5+ dopants and the Li metal electrode. This work suggests dopants that segregate to interfaces/grain boundaries in LLZO will exhibit reactivity that can propagate into bulk and shed light on new mechanisms for the problematic role of oxygen ...

Designing Surface Coating Strategies with Tungsten on Single Crystal NMC Materials by XPS

Advanced Energy Materials, EarlyView.
The compounds Li2WO4 and Li4NiWO6 are identified on the surface of tungsten‐coated single crystal NMC cathode materials. It is shown that Li4NiWO6 is preferred for materials with the best performance. Synthesis routes to obtain materials with either surface species are presented.

Increasing sedentary time, minimum dietary energy requirements, and food security assessment

Applied Economic Perspectives and Policy, EarlyView.
Abstract We compute corrections for sedentary behavior in physical activity levels (PALs) and incorporate them along with corrections for over estimation of basal metabolic rates (BMRs) into threshold caloric intakes, known as minimum dietary energy requirements (MDERs).

Exploring the relationship between growth in online shopping and multichannel food consumers

Applied Economic Perspectives and Policy, EarlyView.
Abstract During the pandemic, many food retailers began offering online shopping options, primarily in reaction to rising consumer demand for such options, which was a response to supply chain disruptions and fear of contagion and food scarcity.

The Ising Model

2013
The Ising model is used to demonstrate how to proceed from a detailed system analysis to a computer simulation of the physics involved. The model itself describes an n-dimensional spin 1/2 lattice which can undergo phase transitions from a ferromagnetic/antiferromagnetic (ordered spins) to a paramagnetic state (unordered spins) with increasing system ...

Extended Ising model

Physical Review B, 1988
In this paper we describe a numerical method of solving the local-density mean-field equations of spatially frustrated lattice models. Using techniques of simulated annealing and simultaneous updating of collective modes, we have been able to locate the global minima of a function with many nearby local minima.

Metastability and the Ising model [PDF]

Journal of Statistical Physics, 1982
We discuss a recent theorem which establishes a precise connection between (i) the approximate degeneracy of the zero eigenvalue for the generator of the Glauber dynamics of the Ising model in a small nonzero field and below the critical temperature, (ii) the existence of a partition of the configuration space into a normal region and a metastable ...

The Ising model on hyperlattices

Journal of Physics A: Mathematical and General, 1992
Summary: We describe the construction of regular lattices in two-dimensional hyperbolic space by means of the action of a discrete subgroup of SU\((1,1)\). We consider an Ising model on such lattices and show how the thermodynamic limit can be handled.

ON ISING'S MODEL OF FERROMAGNETISM

Mathematical Proceedings of the Cambridge Philosophical Society, 1936
Ising discussed the following model of a ferromagnetic body: Assume N elementary magnets of moment μ to be arranged in a regular lattice; each of them is supposed to have only two possible orientations, which we call positive and negative. Assume further that there is an interaction energy U for each pair of neighbouring magnets of opposite direction ...
