A Sustainable Route From Quartz to Bifunctional Material with Adsorbed Lanthanides for Enhanced Fluorescent Activation in Doxycycline Sensing

open access: yesAdvanced Materials Interfaces, EarlyView.
The aim of this study is to develop a sensor material based on natural quartz combined with La(III) and Ce(III), both detected in Ni‐MH batteries, as well as Eu(III), for reliable qualitative and quantitative analysis of doxycycline over a broad concentration range.

Ecologies of indebtedness

open access: yes, 2019
In this chapter I explore the impacts of debt through the lens of ecology in order to reimagine the meaning of indebtedness for a form of globalisation defined by exhaustion. In the first part of the chapter I trace the origins of the contemporary debt society through a discussion of global socio-economic change before moving on to consider the impacts

Stress Response of Aspergillus niger Spores to Copper Surfaces and the Implications for Antifungal Surface Functionalization

open access: yesAdvanced Materials Interfaces, EarlyView.
This study investigates the antifungal efficacy of ultrashort pulsed laser‐induced periodic surface structures (USP‐DLIP) on copper, brass, and steel surfaces. Using Aspergillus niger as a model, the research highlights a 99% reduction in spore viability on 9 µm structured copper surfaces due to enhanced copper ion release. Scanning electron microscopy
