Merging 3D-printing technology and disposable materials for electrochemical purposes: A sustainable alternative to ensure greener electroanalysis
In this study, we propose a solution to these challenges by creating a simple and versatile electrochemical system that combines 3D-printing technology with recyclable disposable materials, such as graphite from an exhausted battery and a stainless-steel screw. Our results demonstrate a novel strategy for developing electrodes and other laboratory-made devices that align with the principles of sustainability and green chemistry. Furthermore, we provide evidence of the effectiveness of the proposed system in an analytical application involving the simultaneous determination of tert-butylhydroquinone, acetaminophen, and levo...

‘A tough experience.’ Why would a scientist serve as an expert witness?
Late last year, the sound of scientific argument echoed through a New York City courtroom packed with legal and financial experts. Studies from top epidemiology journals flashed onto large screens, as lawyers debated their statistical power and whether their conclusions rested on “cherry-picked” data.
Billions of dollars were at stake.
The scientists themselves were absent, and attorneys argued on their behalf. But the crucial issue was whether some of the scientists would be allowed to appear at a future trial, where they would tell jurors that children had developed autism or attention-deficit/hyperactivi...
