Radiation‐Based 3D Dual‐Mode Thermal Management Devices: Advances in Active/Passive Switching for Energy‐Saving Applications

Small, Volume 22, Issue 35, 23 June 2026.
Heating and cooling energy demand account for nearly half of the global energy consumption. SH and RC offer sustainable, zero‐energy strategies, but single‐mode devices lack adaptability. 3D dual‐mode devices, exploiting axial, flipping, and bending deformations, provide reversible switching with dynamic or passive control, representing a promising ...

Unstable Weak Imbibition in Fractured Porous Media: Microfluidic and Theoretical Insights

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Weak imbibition in permeable media is crucial for CO2 geological sequestration, oil and gas extraction, and groundwater contamination and remediation. Previous studies predicted that weak imbibition under favorable viscosity ratios produces stable displacement, but this assumption may fail in fractured porous media.

Silicon allotropes by large‐volume high‐pressure techniques: crystal growth mechanisms, phase diagrams and hexagonal nanostructured Si‐6H by in situ X‐ray diffraction and computational methods

Acta Crystallographica Section B, Volume 82, Issue 3, Page 280-298, June 2026.
In situ X‐ray diffraction is used for exploring Si crystallography and for studying phase‐transformation mechanisms in elemental Si and Na–Si systems. We present original results of hexagonal silicon, Si‐6H and a critical analysis of the past‐decade discoveries of silicon Si‐4H and Si24 using large‐volume high‐pressure techniques.Metastable allotropes ...

From Hair to Healing: Follicular Unit Transplantation for Chronic Ulcer Management—A Case Series

International Wound Journal, Volume 23, Issue 6, June 2026.
ABSTRACT Scalp follicular unit (FU) transplantation is a highly effective yet underutilised minimally invasive technique for promoting healing in chronic and recalcitrant cutaneous wounds. In this case series, five patients with long‐standing nonhealing leg ulcers of mixed etiologies were treated exclusively with single FU grafts harvested from the ...
