Ratiometric Mycotoxin Detection in Living Plants With Dual‐Emissive Nanosensors

Advanced Materials, EarlyView.
A minimally invasive microneedle patch integrates carbon dot‐embedded metal–organic frameworks as nanosensors to detect a key fungal toxin in living plants. The nanosensor produces a ratiometric fluorescence signal that enables early, non‐destructive diagnosis of fungal infection before visible symptoms, offering a new biomaterials‐based strategy for ...

Test method for axial force at pile top in centrifugal model tests on pile-net composite foundation

Yantu gongcheng xuebao
The pile-net composite foundation is a common soft soil reinforcement measurement. In order to analyze the pile-soil stress ratio, it is necessary to measure the axial force at the pile top and the soil pressure between piles in the centrifugal model ...

Numerical evaluation of the soil behavior during pipe-pile installation using impact and vibratory driving in sand [PDF]

, 2020
Pipe-piles are installed using impact or vibratory driving which influences the soil in different ways including the void ratio and stress distribution. Such complex problems are hard to investigate on the field as well as using numerical methods.

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

Advanced 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
