A functionally driven variable‐cell size and gradient‐conductive coated TPMS structure was developed. Accordingly, stepwise longitudinal gradient impedance was realized, achieving absorption‐dominant EMI shielding (absorptivity≈0.85) with an EMI SET of ≈ 59 dB, for 10 mm‐thick composites. Further increasing the thickness of composites to 20 mm achieved

Background Left ventricular ejection fraction (LVEF) is used as quantitative parameter to evaluate myocardial function. However, interobserver variation, limited reproducibility, and dependence on pre-load and after-load reduces its accuracy. The fall in

Boron‐oxide‐assisted particle engineering stabilizes O3‐type layered cathodes for sodium‐ion batteries by mitigating phase transitions and lattice strain. Acting as flux and structural modifier, boron forms submicron hexagonal platelets with (003) facets and expanded Na‐layer spacing, enabling rapid Na⁺ diffusion and mechanical resilience.

Evidence for a Dichotomy in the Interior Structures of Jupiter and Saturn from Helium Phase Separation [PDF]
We examine the comparative thermal evolution of Jupiter and Saturn, applying recent theoretical results for helium’s immiscibility in fluid metallic hydrogen.

Greening Under Pressure: Climate Change Exposure and Eco‐Innovation
ABSTRACT This study explores the impact of climate change exposure on corporate eco‐innovation. Recognizing the urgent need to address climate change, we examine how firms directly respond to climate risks through eco‐innovation. Our findings indicate that climate change exposure is positively associated with corporate eco‐innovation.

Variable Temperature Studies of Two Calcium Uranates α‐Ca3UO6 and Ca2UO5
The structures and thermal responses of the calcium uranates α‐Ca3UO6 and Ca2UO5 were investigated using in situ synchrotron x‐ray diffraction and neutron powder diffraction. Despite the very similar chemical compositions, the structural response of the two calcium uranates is shown to be complex and varied.

Graphical abstract illustrating the niobic acid precipitation process applied and the product obtained. Abstract This study investigates the precipitation of niobic acid (Nb2O5.nH2O) from potassium niobate solution with addition of sulphuric acid, and its subsequent thermal conversion into niobium oxide (Nb2O5). Thermodynamic modelling with PHREEQC and
