Decreasing the Cost of Morphing in Adaptive Morphogenetic Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
Shape‐morphing propulsive limbs enhance locomotion across land‐to‐water transitions, but prior designs rely on thermally responsive components, coupling performance to environmental temperature. This study introduces a pressure‐responsive mechanism that reduces morphing energy costs, enables rapid transitions, and minimizes failure modes.

The Role of Porous Carbon Inserts on the Performance of Polymer Electrolyte Membrane Fuel Cells: A Parametric Numerical Study

open access: yesEnergy Technology, Volume 10, Issue 12, December 2022., 2022
A computational fluid dynamic study is conducted to investigate the effects of using porous carbon inserts (PCIs) on water management and the performance of proton exchange membrane fuel cells. The results show that employing PCI leads to a more efficient water removal from the fuel cell and higher oxygen transport throughout the cell, which ...

Data‐Driven Review on Aerogels and Polymeric Aerogels

open access: yesAngewandte Chemie International Edition, Accepted Article.
Thoroughly data‐driven review on chemistry–properties–applications of aerogels is provided. Aerogel is a category of solid materials having homogeneous, highly porous nanostructures. Unique physicochemical properties of aerogels have attracted much attention in wide fields due to their potentials for energy/environmental issues in the 21st century ...

A highly efficient and durable solar evaporator based on hierarchical ion‐selective nanostructures

open access: yesEcoMat, Volume 5, Issue 2, February 2023., 2023
A PSS@PVA@OCB hydrogel‐based hierarchically nanostructured evaporator with vertically aligned micro water transportation pathways and water confined ion‐selective nanochannels is constructed. Based on the fabricated evaporator, an exciting water evaporation rate of 3.68 kg m−2 h−1 and reliable long‐term salt resistance are achieved.
