Transforming Coal Waste into Surface‐Engineered Carbons for Lithium–Sulfur Batteries
Batteries &Supercaps, EarlyView.Coal waste is transformed into surface‐engineered porous carbons that suppress polysulfide shuttling and boost Li–S battery performance. Slow redox kinetics and polysulfide shuttling hinder the practical deployment of lithium–sulfur (Li–S) batteries.

PROBLEM WITH CONDITIONS SAMARA FOR FRACTIONAL DIFFUSION EQUATION IN THE HALF [PDF]
Vestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2015 In this paper, we construct a solution of a nonlocal boundary value problem with the condition Samarskii for a fractional diffusion equation in the half.

ChemistryEurope, EarlyView.The linear and nonlinear (chir)optical properties of four oligoamide foldamers with different donor groups are studied by means of time‐dependent density functional theory calculations. It is shown that stronger donors yield larger hyperpolarizabilities due to low‐lying charge–transfer states. The agreement with the experiments concerning the key bands

Existence and properties of traveling waves for doubly nonlocal Fisher-KPP equations
Electronic Journal of Differential Equations, 2019 We consider a reaction-diffusion equation with nonlocal anisotropic diffusion and a linear combination of local and nonlocal monostable-type reactions in a space of bounded functions on R^d. Using the properties of the corresponding semiflow, we prove

Correcting Errors in the Adsorbed Intermediates of CO2 Electroreduction
Carbon Energy, EarlyView.Flying over Jacob's ladder of density functional approximations: chemical accuracy in the DFT‐based modeling of CO2 reduction electrocatalysis can be approached with our simple semiempirical method to deconvolute and correct gas‐phase errors and adsorbed‐phase errors.

Diffusion with nonlocal boundary conditions
Journal of Functional Analysis, 2016 We consider second order differential operators $A_ $ on a bounded, Dirichlet regular set $ \subset \mathbb{R}^d$, subject to the nonlocal boundary conditions \[ u(z) = \int_ u(x)\, (z, dx)\quad \mbox{for } z \in \partial . \] Here the function $ : \partial \to \mathscr{M}^+( )$ is $ (\mathscr{M} ( ), C_b( ))$-continuous with $0\leq (z,

Canadian Journal of Statistics, EarlyView.Abstract We analyze the effect of regulatory capital constraints on financial stability in a large homogeneous banking system using a mean‐field game (MFG) model. Each bank holds cash and a tradable risky asset. Banks choose absolutely continuous trading rates in order to maximize expected terminal equity, with trades subject to transaction costs ...

Toward Safer and Sustainable Lithium Metal Batteries: Fluorine‐Free Solid Polymer Electrolytes
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.An analysis to assess the impact of fluorine in polymer electrolyte‐based lithium metal batteries has been conducted. It has been demonstrated that fluorine‐free LiTIM salt delivers a electrochemical performance similar to that of its fluorinated analogue salts, given the complete lithium dissociation in coordination with PEO and the restricted anion ...
