New equilibrium ensembles for isolated quantum systems
, 2018 The unitary dynamics of isolated quantum systems does not allow a pure state to thermalize. Because of that, if an isolated quantum system equilibrates, it will do so to the predictions of the so-called "diagonal ensemble" $\rho_{DE}$.

Unified Approach to Thermodynamic Optimization of Generic Objective Functions in the Linear Response Regime [PDF]
Entropy, 2016 While many efforts have been devoted to optimizing the power output for a finite-time thermodynamic process, thermodynamic optimization under realistic situations is not necessarily concerned with power alone; rather, it may be of great relevance to optimize generic objective functions that are combinations of power, entropy production, and/or ...

, 2023 We explore the feasibility and potential characteristics of photosynthetic light-harvesting on exo-planets orbiting in the habitable zone of low mass stars ($< 1$ M$_{\odot}$). As stellar temperature, $T_{s}$, decreases, the irradiance maximum red-shifts out of the $400 \textrm{nm} \leq λ< 750$ nm range of wavelengths that can be utilized by ...

Advanced Materials, EarlyView.Electrochemical CO2RR is a key technology for converting CO2 into chemicals, but there remains a gap between “laboratory science” and “engineering practice” in current research. This review establishes a multi‐scale research framework, encompassing atomic‐level characterization, microenvironment regulation, external field‐assisted optimization, and AI ...

Diverse Cation Exchange in Layered Titanate Nanostructures for Tailored Catalysis
Advanced Materials, EarlyView.H+(H3O+)‐intercalated layered titanate enables stable intercalation of 42 single‐metal and multication combinations. Alkali‐metal intercalation tunes Rh charge density, yielding an efficient propylene hydroformylation catalyst. These results establish a generalizable intercalation platform for rational catalyst design and provide a library supporting ...

Advanced Materials, EarlyView.This work introduces an atomic‐level engineered bimetallic MOF Platform that resolves the inherent trade‐off between environmental stability and propulsion efficiency. By integrating robust Fe‐O bonds for hydrolysis resistance and enabling d‐orbital charge transfer (Fe3+→Cu2+) for enhanced photothermal conversion, the design achieves a highly durable ...

Combinatorial Information Theory: I. Philosophical Basis of Cross-Entropy and Entropy [PDF]
, 2007 This study critically analyses the information-theoretic, axiomatic and combinatorial philosophical bases of the entropy and cross-entropy concepts. The combinatorial basis is shown to be the most fundamental (most primitive) of these three bases, since ...

Journal of Cleaner Production, 2020 Sustainable energy is a current key priority across the globe. Hence, renewable energy sources have been widely accepted as potential substitutes for fossil fuels in the existing energy infrastructures. A recent report showed that photovoltaic power generation constituted around 100 GW out of 2,378 GW of the global renewable power capacity installed in

Advanced Materials, EarlyView.An unsaturated coordination chemistry strategy activates a quasi‐solid‐state redox pathway by strengthening NaPSs adsorption and accelerating redox conversion kinetics, thereby overcoming the kinetic bottlenecks that limit high‐rate performance. In situ transmission electron microscopy, combined with newly developed Na‐ion diffusion descriptors ...
