Electrocatalytic nitrate reduction (NO3RR) is a promising method for pollutant removal and ammonia synthesis and involves the transfer of eight electrons and nine protons. As such, the rational design of catalytic interfaces with enhanced mass transfer is crucial for achieving high ammonia yield rates and Faradaic efficiency (FE). In this work, we incorporated a Cu-bipyridine catalytic interface and fabricated crystalline 2D covalent organic framework films with significantly exposed catalytic sites, leading to improved FE and ammonia yield (FE = 92.

On the eve of the start-up of our new animal facility we were notified that a research centre was putting part of its zebrafish holding facility (29 racks, accessories, water treatment unit) up for sale. Although the originally planned room was designed for six double racks, but encouraged by the increasing use of the zebrafish model, we decided to seize the opportunity, purchase the equipment and utilize it to create a larger configuration and an independent quarantine to protect the main facility.

Method: A cross-sectional pilot evaluation study with mixed methodology involving eight primary schools (four in intervention group and four in control group). For the quantitative analysis, 16 systematic observations were performed in the schoolyards of both groups.
