Energy Landscapes in Chemical Reactions and Transport

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Kinetics/dynamics of chemical reactivity and transport of chemical species in a solid are both determined by the energy landscape in which they take place. Discussing common grounds but also distinct differences may help in advancing the understanding in both fields.

On the Method of Harmonic Balance for Lumped‐Element Transformer Models

International Journal of Circuit Theory and Applications, EarlyView.
The steady‐state solution of a lumped‐element transformer model with a dry friction‐like hysteresis model depicting the magnetic core is of interest. The harmonic balance method efficiently solves this stiff system. We derive the harmonic balance algorithm, enhance it with performance and convergence improvements, and demonstrate its efficiency by ...

“Win‐Win” Structural Engineering of Chinese Herb Residues‐Derived Porous Graphitic Carbons: Decoupling the Porosity‐Graphitization Antagonism for Ultrahigh‐Rate Supercapacitors

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work proposes a strategy that overcomes the porosity‐graphitization antagonism in carbon materials, converting Sargentodoxa cuneata residue into porous graphitic carbons to enable sustainable, high‐performance energy storage from biomass waste. The antagonism between porosity and graphitization critically limits carbon supercapacitor performance ...

Crystal Plane Engineering of Zn Nanosheet Arrays Toward Robust Hybrid Capacitive Energy Storage

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work demonstrates a dual‐phase ZnCl2 concentration strategy dynamically switching Zn2+ solvation from [Zn(H2O)6]2+ to [ZnCl(H2O)5]+. The solvation shift steers the epitaxial growth of Zn nanosheet arrays, favoring the (002) crystal plane over (101).

Off‐Grid Solar Systems: An Experimental Work and Systematic Techno‐Economic Analysis

Energy Science &Engineering, EarlyView.
In the study mentioned above, experimental monitoring and economic evaluation of two off‐grid PV systems were conducted using a low‐cost data logger. The results suggest that basic DC systems are economically feasible compared to grid power, but that AC systems require further cost‐cutting to achieve financial viability.
