Decoupling Activation and Preservation: Architectural Design Principles of Organic Frameworks for Selective Photocatalytic Methane Oxidation

open access: yesAdvanced Materials, EarlyView.
Selective methane (CH4) photooxidation emerges from architectural decoupling of activation and preservation. Programmable organic semiconductor frameworks spatially organize oxidative flux and intermediate residence, separating reaction zones from product domains to synchronize activation strength with stabilization and establish a selective oxidation ...

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

open access: yesAdvanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Biodegradable Wireless Soil Urea Sensor Using Metamaterial Perfect Absorber for Distributed Deployment in Precision Agriculture

open access: yesAdvanced Materials Technologies, EarlyView.
In this study, we propose a biodegradable wireless soil urea sensor for precision agriculture. The sensor's electromagnetic response varies depending on the urea concentration, allowing the measurement of relative soil urea concentrations by analyzing the time‐transient electromagnetic response.

Conformable Ferrimagnetic Tattoo Electrodes for Plant Electrophysiology

open access: yesAdvanced Materials Technologies, EarlyView.
The newly developed ferrimagnetic tattoo electrode is capable of measuring plant electrophysiological activity outside the Faraday cage. Its ability to adhere without damaging the plant tissue allows long‐term recordings. This premise opens new avenues for in‐field monitoring of plant health through electrophysiology.

MANGO‐“Fruitcage”: A Conditional Photocage Utilizing a Fluorescence Light‐Up Aptamer

open access: yesAdvanced Optical Materials, EarlyView.
Fruitcaging ‐ a proof of concept study of a conditional photocage (Thiazol‐Orange) activated upon binding to the fluorescence light up aptamer (Mango). The prolongation of the excited state lifetime explains the redirection of the reactive pathway toward photocleavage and provides a sensitive spectroscopic readout.

A Multidirectional Textile Interface for Remote Control Using Dynamic Area‐Based Capacitance Modulation

open access: yesAdvanced Robotics Research, EarlyView.
Here, we present a textile, wearable capacitive interface enabling multidirectional remote control by dynamically modulating electrode overlap and spacing via a freely gliding upper electrode. A forearm‐mounted prototype drives robotic and media tasks with 12–15 ms latency, maintains < 0.8% drift after 500 cycles, and remains stably functional at 90 ...

The Impact of Transportation Infrastructure on Green Total Factor Productivity

open access: yesInternational Journal of Social Sciences and Public Administration
This study examines the effect of transportation infrastructure on Green Total Factor Productivity (GTFP) across 50 countries from 2001 to 2021. Using a non-radial, non-oriented Slacks-Based Measure (SBM) to measure GTFP and explores the impact of infrastructure development. Results show that transportation infrastructure positively contributes to GTFP.
