Correcting Errors in the Adsorbed Intermediates of CO2 Electroreduction

open access: yesCarbon Energy, Volume 8, Issue 2, February 2026.
Flying over Jacob's ladder of density functional approximations: chemical accuracy in the DFT‐based modeling of CO2 reduction electrocatalysis can be approached with our simple semiempirical method to deconvolute and correct gas‐phase errors and adsorbed‐phase errors.

Ultra High Step‐Up Soft Switching Converter Based on the Interleaved Structure

open access: yesEnergy Science &Engineering, Volume 14, Issue 1, Page 540-556, January 2026.
The proposed topology provides high voltage gain and enhanced efficiency at low duty cycles, thereby reducing conduction losses in the switches. Its interleaved structure ensures current sharing, while the switches experience both low voltage and low current stress, further decreasing conduction losses.
