Self‐Assembled Hollow Gyroids with Bicontinuous Mesostructures: A Highly Robust Electrocatalyst Fixation Platform

open access: yesAdvanced Materials, EarlyView.
The hollow gyroid carbon (HGC), synthesized via the self‐assembly of block copolymers and vapor pressure‐induced hollow structuring, provides a robust platform for embedding Pt nanoparticles. The HGC morphology facilitates efficient mass transport while the pyridine N inherent in the block copolymer enhances electrical conductivity and electrochemical ...

Reducing the Environmental Impact of Midblock Crossing [PDF]

open access: yesarXiv
Accommodating pedestrians crossing midblock has been shown to have harmful environmental consequences because of increased fuel consumption and CO2 emissions. Somewhat surprisingly, no studies were devoted to mitigating the environmental impact of midblock crossing.

A Bio‐Inspired Perspective on Materials Sustainability

open access: yesAdvanced Materials, EarlyView.
This perspective discusses natural materials as inspiration for sustainable engineering designs and the processing of materials. First, circularity, longevity, parsimony, and activity are presented as essential material paradigms. The perspective then uses many examples of natural and technical materials to introduce principles such as oligo ...

Constrained Optimal Fuel Consumption of HEV:Considering the Observational Perturbation [PDF]

open access: yesarXiv
We assume accurate observation of battery state of charge (SOC) and precise speed curves when addressing the constrained optimal fuel consumption (COFC) problem via constrained reinforcement learning (CRL). However, in practice, SOC measurements are often distorted by noise or confidentiality protocols, and actual reference speeds may deviate from ...

Covalent Organic Frameworks for Photocatalysis

open access: yesAdvanced Materials, EarlyView.
This review provides an overview of recent advances in covalent organic frameworks (COFs) for photocatalysis, focusing on sustainable energy applications like water splitting, hydrogen peroxide generation, and CO2 and N2 reduction. It discusses design principles, structure‐function relationships, challenges in COF photocatalysis, and strategies to ...
