Butterfly‐Inspired Hierarchical Hybrid Composites for Lightweight Structural Thermal Management Applications

open access: yesAdvanced Functional Materials, EarlyView.
Emulating nature's unparalleled engineering, this work introduces butterfly‐inspired hybrid composites for high‐performance transportation and defense sectors. Leveraging biomimicry, these lightweight composites feature butterfly leg‐inspired hierarchical fibrous assemblies and butterfly wing‐inspired sandwich‐structured architecture, to achieve ...

Paley-Wiener theorem for the Joint-Eigenspace Fourier transform on noncompact symmetric spaces [PDF]

open access: yesarXiv
This paper conducts a geometric analysis of the Joint-Eigenspace Fourier transform of the symmetric space of the non-compact type. Our study shows how the Poisson transform builds up the well-known Helgason Fourier transform for an analysis of the complete duality of the underlying symetric space. Among other results, we establish an inversion formula,

Shape‐Stabilization of Phase Change Materials with Carbon‐Conscious Poly(hydroxy)Urethane Foams

open access: yesAdvanced Functional Materials, EarlyView.
Poly(hydroxy)urethane (PHU) foam, derivable from carbon dioxide (CO2) and bio‐based resources, is a promising material platform for shape‐stabilizing phase change materials (PCMs). We demonstrate the encapsulation of both paraffins and calcium chloride hexahydrate in PHU foam, achieving 48 stable thermal cycles by introducing 5 wt.% barium carbonate ...

Extreme Water and Architecture. Building whitout joint

open access: yes, 2010
The objective of the design was to formalize an aggressive natural phenomenon and then use it to imply a complex geometry. The structure needed to be aligned with the edges of this arbitrary form and was to be modulated so that it could be dismantled and mounted elsewhere. To this end, we proposed triangular faces connected only by the edges and not by

Active Thermal Field Integration for Marangoni‐Driven Salt Rejection and Water Collection

open access: yesAdvanced Functional Materials, EarlyView.
A thermal gradient fabric (TGF) evaporator with an auxiliary active thermal field can simultaneously increase evaporation rates and achieve long‐term salt rejection. The auxiliary active thermal field is well integrated with solar energy to construct moderate, extensive, and circulating Marangoni flow for salt rejection.
