Wood‐Derived 3D Conductive Cellular Bio‐C@YB2C2 Ceramics for Efficient Electromagnetic Shielding and Joule Heating

open access: yesElectron, EarlyView.
Herein, a biomimetic, anisotropic, robust wood‐derived 3D conductive Bio‐C@YB2C2 framework was synthesized by in situ boron/carbon thermal reduction reaction on the carbonized wood template. The as‐obtained Bio‐C@YB2C2 composites accurately inherit the specific microstructure of natural wood, providing pathways for terahertz wave dissipation.

Turbulence‐Intensity Effects on the Aerodynamic Performance of an H‐Type Darrieus Wind Turbine: A URANS Parametric Study

open access: yesEnergy Science &Engineering, EarlyView.
Turbulence intensity from 1% to 25% was parametrically tested on a three‐bladed H‐type Darrieus rotor across five tip speed ratios (TSRs) using two‐dimensional URANS. The optimal TSR proved the most efficient and most robust operating point simultaneously, with Cp losses capped at 5.8% even at TI = 25%. ABSTRACT The effect of inlet turbulence intensity

A Geographic Information System (GIS)–CRiteria Importance Through Intercriteria Correlation (CRITIC) Framework for Selecting Solar Photovoltaics Sites: A Case Study

open access: yesEnergy Science &Engineering, EarlyView.
A novel framework integrating environmental constraints, topography, infrastructure accessibility, and solar irradiation was developed to identify optimal utility‐scale solar photovoltaics (PV) sites in Lithuania. Western and central Lithuania showed the highest suitability for future solar PV expansion.
