Dual‐Molten‐Salt Etching Strategy Enables Built‐in Electric Field in Mo‐MXene/NiFeSe Heterostructure for Superior OER Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A dual‐molten‐salt etching strategy was employed to construct a built‐in electric field in the Mo‐MXene/NiFeSe heterostructure to achieve excellent oxygen evolution reaction. Transition metal selenides have emerged as potential catalysts for the oxygen evolution reaction, yet their practical implementation faces two fundamental challenges: irreversible

Estimation of the GCV of Coal Using Real‐Time Plant Data

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT Online or real‐time strategies of estimating the gross calorific value (GCV) of coal are still not fully explored in academic literature, even though both conventional and sophisticated offline methods for estimating the GCV are well described.

A Lower Bound on the Critical Momentum of an Impurity in a Bose–Einstein Condensate

open access: yesComptes Rendus. Mathématique
In the Bogoliubov–Fröhlich model, we prove that an impurity immersed in a Bose–Einstein condensate forms a stable quasi-particle when the total momentum is less than its mass times the speed of sound. The system thus exhibits superfluid behavior, as this

Renormalization group analysis for thermal turbulence

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1997
Renormalization group theory is applied to thermal turbulence. Turbulent fluxes for the flow are accounted for by repeatedly recasting the governing equations with the smallest scales represented by effective larger scales.

Strain analysis of black‐to‐yellow phase transitions in CsPbI3

open access: yesInfoMat, EarlyView.
All‐inorganic metal‐halide perovskite CsPbI3 shows strong potential for photovoltaic applications. Here strain analysis is used to probe the mechanisms behind the instability of its photoactive black phase. The results indicate that a relatively large positive (e1–e2) strain is the primary driver of the black‐to‐yellow phase transition.

Autoantibody signatures in children with celiac disease, juvenile idiopathic arthritis, and polyautoimmunity

open access: yesJPGN Reports, EarlyView.
Abstract Objective To determine if multiplex autoantibody arrays can identify novel biomarker signatures in children with one or multiple autoimmune diseases (polyautoimmunity). Methods Plasma collected from children (18 years or younger) in the Boston Children's Hospital Precision Link Biobank for Health Discovery between January 2007 and June 2021 ...
