Surfactant-free interfacial growth of graphdiyne hollow microspheres and the mechanistic origin of their SERS activity

Nature Communications, 2023
As a two-dimensional carbon allotrope, graphdiyne possesses a direct band gap, excellent charge carrier mobility, and uniformly distributed pores. Here, a surfactant-free growth method is developed to efficiently synthesize graphdiyne hollow microspheres

Comparison of Consumption Data and Phenotypical Antimicrobial Resistance in E. coli Isolates of Human Urinary Samples and of Weaning and Fattening Pigs from Surveillance and Monitoring Systems in Germany

Antibiotics, 2021
Antimicrobial resistance (AMR) data from humans are mostly collected from clinical isolates, whereas from livestock data also exist from colonizing pathogens. In Germany, livestock data are collected from clinical and nonclinical isolates.

Ubiquity, Hazardous Effects, and Risk Assessment of Fragrances in Consumer Products [PDF]

Current Treatment Options in Allergy, 2021
The main aims of fragrances are to create pleasing scents or to mask unpleasant odors. We hereby review their main exposure sources, presumed benefits, and unwanted effects, with special attention to allergic contact dermatitis (prevalence, regulatory environment, risk assessment methodology, and preventive measures).Fragrances elicit positive emotions

Consumer protection and risk assessment: sensitising substances in consumer products [PDF]

Allergo Journal International, 2019
The human immune system is confronted daily with a large, chemically-varied range of potentially sensitising substances. Skin sensitising substances are found, above all, in a plethora of consumer products, e. g. cosmetics, jewellery, earrings, toys, textiles, leather, other everyday commodities and, in some cases, also tattoos.
