Kinetically Dormant Ni‐Rich Layered Cathode During High‐Voltage Operation

Advanced Materials, EarlyView.
Ni‐rich layered cathode remains thermodynamically reversible but undergoes dramatic kinetic degradation at high voltage, leading to the commonly observed capacity loss that in fact can be recovered under kinetic‐free conditions. Such kinetic dormant behavior highly synchronizes with the lattice strain evolution stemming from layered/rock‐salt ...

Multiple Roles of Alkanethiolate‐Ligands in Direct Formation of H2O2 over Pd Nanoparticles

Angewandte Chemie, Volume 134, Issue 51, December 19, 2022., 2022
Under the reaction conditions of direct H2O2 formation over alkylthiolate(RS) decorated Pd, we find that the RS is oxidized yielding RSO2 as the effective ligand. The RSO2 ligand shows superior ability for proton transfer to the intermediate surface species OOH, which accelerates the formation of H2O2.

Radiating Collapse with Vanishing Weyl stresses

, 2004
In a recent approach in modelling a radiating relativistic star undergoing gravitational collapse the role of the Weyl stresses was emphasised. It is possible to generate a model which is physically reasonable by approximately solving the junction ...

Synthesis and Photothermal Processing of Silicon‐Based Nanoconfined MXenes

Advanced Materials Interfaces, EarlyView.
Intercalation of titanium carbide (Ti3C2Tx) MXenes with aminopropyl terminated polydimethylsiloxane (amino‐PDMS) is demonstrated through ion‐exchange method followed by photonic curing (PC) using xenon flashlamp. The intercalation and PC result in enhanced interlayer spacing of Ti3C2Tx of 13.5 and 11 nm, respectively. Furthermore, conversion of PDMS to

Online machine learning modeling and predictive control of nonlinear systems with scheduled mode transitions

AIChE Journal, Volume 69, Issue 2, February 2023., 2023
Abstract This work develops a model predictive control (MPC) scheme using online learning of recurrent neural network (RNN) models for nonlinear systems switched between multiple operating regions following a prescribed switching schedule. Specifically, an RNN model is initially developed offline to model process dynamics using the historical ...

On the Resistance Coefficients for Heat Conduction in Anisotropic Bodies at the Limit of Linear Extended Thermodynamics

Entropy
This study examines the thermal conduction resistance in anisotropic bodies using linear extended irreversible thermodynamics. The fulfilment of the Onsager Reciprocal Relations in anisotropic bodies, such as crystals, has been demonstrated.

Nonequilibrium Temperature and Thermometry in Heat-Conducting Phi-4 Models

, 2008
We analyze temperature and thermometry for simple nonequilibrium heat-conducting models. We show in detail, for both two- and three-dimensional systems, that the ideal gas thermometer corresponds to the concept of a local instantaneous mechanical kinetic

Finite-Time Processes In Quantum Thermodynamics: The Limits Of Irreversibility [PDF]

The emergence of irreversibility in physical processes, despite the fundamentally reversible nature of quantum mechanics, remains an open question in physics. This thesis explores the intricate relationship between quantum mechanics and thermodynamics, with a particular focus on minimizing entropy production in finite-time processes. By employing tools

Weakly nonlocal irreversible thermodynamics

, 2003
Weakly nonlocal thermodynamic theories are critically revisited. A relocalized, irreversible thermodynamic theory of nonlocal phenomena is given, based on a modified form of the entropy current and new kind of internal variables, the so called current ...
