Low Loss Substrate-Integrated Waveguide Using 3D-Printed Non-Uniform Honeycomb-Shaped Material

open access: yesIEEE Access, 2020
Despite the low cost and easy fabrication afforded by 3D printing technology, high dielectric loss of the 3D printing filament degrades the performance of 3D printed radio frequency electronics at high frequencies.

A Unified Theoretical Model for Hysteretic Soil Freezing‐Thawing Characteristic Curves in Saline Soils: Model Development, Experimental Validation, and Simulation

open access: yesWater Resources Research, Volume 62, Issue 11, November 2026.
Abstract Soil freezing‐thawing characteristic curve (SFTCC) is crucial for cold region engineering and hydrological simulations. Most existing hydrothermal models simplify thawing as an inverse freezing process, neglecting the hysteresis effect during freeze‐thaw cycles (FTC).

POMs‐GibbsNet: A Deep Neural Network for the Prediction of Thermodynamic Parameters of Polyoxometalates

open access: yesJournal of Computational Chemistry, Volume 47, Issue 28, October 30, 2026.
Polyoxometalate thermochemistry is often limited by the high cost of DFT vibrational frequency calculations. POMs‐GibbsNet uses molecular structure, electronic, and QTAIM descriptors to predict thermal Gibbs free‐energy corrections without calculating the Hessian.
