Near‐Unity Selectivity Inversion Between CO2 Electroreduction and H2 Evolution via Atomic Coordination Editing

open access: yesAdvanced Science, EarlyView.
Atomic coordination editing functions as an on/off switch that toggles single‐atom catalysts between CO2 electroreduction and hydrogen evolution. ABSTRACT Precise atomic coordination editing of single‐atom catalysts (SACs) provides an effective strategy to tune their electronic structures and catalytic selectivity. Yet, achieving near‐unity selectivity

Thermodynamics of binary mixtures of non-electrolytes: Molar excess Gibbs free energy of mixing [PDF]

open access: yes, 1992
398-402Vapour liquid equilibrium data have been measured at 308.15 K for 1,2-dichloroethane (i) + pyridine (j), + a-picoline (j), + n-heptane (j) and n-heptane (i) + a-picoline (j) mixtures and the same have been utilized to calculate excess Gibbs free ...

Non‐Equilibrium Synthesis of Whitlockite Assisted by Localized H2O Vapor Pressure

open access: yesAdvanced Science, EarlyView.
A carbon substrate acts as a microheater during intense pulsed light irradiation, enabling rapid heating and cooling for whitlockite formation. In contrast to conventional white ceramic synthesis with weak photothermal response, this platform concentrates thermal energy locally and promotes phase‐selective crystallization under ultrafast ...

Comparison of three excess Gibbs energy models for the CaO-Al2O3 and CaO-SiO2 solid solutions

open access: yes, 2000
The paper suggests an application of the real solution model for prediction of the Gibbs free energy values of the CaO-Al2O3 and CaO-SiO2 systems. Particularly, the importance of the excess Gibbs free energy has been emphasized.

Freestanding Bamboo‐Like Nitrogen‐Doped Carbon Nanofibers/PANI Dual‐Conductive Cathodes via Interfacial Engineering for High‐Performance Lithium–Sulfur Batteries

open access: yesAdvanced Science, EarlyView.
Bamboo‐like nitrogen‐doped carbon fibers (BNCFs) were synthesized via a vapor‐liquid‐solid catalytic growth method and further integrated with polyaniline to fabricate a freestanding BNCFs/S/PANI cathode. The PANI coating and BNCFs framework synergistically establish an interconnected conductive network with abundant nitrogen‐active sites, thereby ...

Gibbs sampling will fail in outlier problems with strong masking [PDF]

open access: yes, 1995
This paper discusses the convergence of the Gibbs sampling algorithm when it is applied to the problem of outlier detection in regression models. Given any vector of initial conditions, theoretically, the algorithm converges to the true posterior ...

Enhancing All‐Solid‐State Batteries Performance Through Thickness Control and Surface Passivation of Thermally Evaporated Lithium Metal Anodes

open access: yesAdvanced Science, EarlyView.
This study demonstrates that thermally evaporated lithium anodes combined with LiF passivation provide a high‐performance thin anode design for next‐generation ASSBs. This approach increases the critical current density from 1.6 to 2.6 mA cm−2, enabling full cells to achieve over 500 and 300 cycles at 1.5 and 3 mA cm−2, respectively, outperforming even
