A Crystallographic Shear Driven by Oxygen Insertion in (LuFeO3)nLuFe2O4

open access: yesChemistryEurope, EarlyView.
Layered structures (LuFeO3)nLuFe2O4 exhibit a common structural transformation upon oxygen uptake. Although the LuFeO3 units do not directly participate in oxygen insertion, these inactive layers nevertheless influence the temperature at which oxygen absorption occurs.

Amorphous Protective Layers to Reshape Inorganic‐Rich Interphases for High‐Voltage Sodium‐Ion Batteries

open access: yesCarbon Energy, EarlyView.
Herein, we propose a straightforward and efficacious strategy of surface modification for P2‐type Na0.7Li0.03Mg0.03Ni0.27Mn0.6Ti0.07O2 cathode in high‐voltage Na‐ion batteries. The stable amorphous SiO2 coating layer on the cathode surface contributes to a strong, dense, fluorine and silicon‐rich cathode–electrolyte interphase, which inhibits the side ...

Detection and mitigation of false data injection attack in DC–DC synchronous boost converter: A real‐time implementation using shallow neural network model

open access: yesIET Power Electronics, EarlyView., 2023
This article proposes a neural network‐based cyber attack detection and mitigation scheme to detect and mitigate false data injection attacks on the sensors. Neural networks are used for the prediction of duty; a combination of a data sampler and a binary attack detector detects the presence of an attack.

Water and Carbon Dioxide‐Resistant Cathode With Radial Phase and Valence Gradient Distribution via Composition Regulation

open access: yesCarbon Energy, EarlyView.
Precise regulation of radial sodium‐ion distribution, phase structure, and transition metal valence in P2/O3 composite cathodes without grain boundary significantly enhances resistance to an environment with high humidity and high concentration of CO2.

Structural Aspects of Lithium‐Ion Conduction in the Phosphidotitanate Li8TiP4 and Its Comparison With Li7+5xTa1−xP4 and Li8−xTi1−xTaxP4

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT The chemical system Li/Ti/P has previously been subject to intensive investigation. However, reliable structural data for the reported phases have remained elusive. Motivated by the growing interest in phosphorus‐based lithium‐ion conductors, we have reinvestigated the synthesis, crystal structure, and physical properties of Li8TiP4.

Optimal mud pressure design using nonlinear failure criteria for wellbores in shaley sedimentary reservoir

open access: yesDeep Underground Science and Engineering, EarlyView.
The present study uses the Modified Mohr‐Coulomb true‐triaxial failure criterion (MMC_TT), which predicts the strength of rock better than the MGC criterion in laboratory true‐triaxial tests to overcome the limitations. Moreover, based on the data from previously published five vertical wells in the Krishna‐Godavari basin (K‐G basin), an empirical ...

Nanofiber‐Confined 2H‐NbSe2 With a Li2S Activation Interface for 10 C Fast‐Charging Lithium–Sulfur Batteries

open access: yesEcoEnergy, EarlyView.
A flexible carbon nanofiber‐confined 2H‐NbSe2 membrane (2H‐NbSe2@CNFM) serves as an electrocatalytic reactor to construct a Li2S activation interface, enabling rapid and reversible Li2S conversion. This tailored interface markedly enhances rate performance and cycling stability, offering a robust strategy for advancing high‐power Li‐S batteries ...

Non‐stationary forest responses to hotter droughts: a temporal perspective considering the role of past legacies

open access: yesEcography, EarlyView.
Global change is altering forests worldwide, with multiple consequences for ecosystem functioning. Temporal changes in climate, and extreme, compounded weather events like hotter droughts are affecting the demography, composition and function of forests, leading to a highly uncertain future.

Synthesis of Sulfur Enriched Cyclohexenes via the Tungsten‐Promoted Dearomatization of a Phenyl Sulfone

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A method for synthesizing sulfur‐substituted cyclohexenes is reportedthat leverages the η2‐coordination of a phenyl sulfone to [WTp(NO)(PMe3)] (Tp = trispyrazolylborate). Three sequential protonation and nucleophilic additions to the bound arene, followed by oxidative decomplexation, affords functionalized cyclohexenes bearing sp3‐ and sulfur‐enriched ...
