Small Structures, EarlyView.Flexoelectric polarization is harnessed to dynamically enhance phosphatase‐mimicking catalysis in Gd‐based nanoflowers, enabling ultrasound‐responsive and efficient biophosphate ester hydrolysis through strain‐induced electronic modulation. Phosphatase‐mimicking nanozymes provide highly stable enzyme‐like activity but remain limited by their static ...

Archaeometry, EarlyView.Abstract This paper presents the first direct evidence of the slags produced during the cementation alloying process of Cu with speiss inside ceramic crucibles, thus representing Cu alloying with As in Middle Kingdom Egypt. The settlement deposits from the Middle Bronze Age were excavated on Elephantine Island, within modern Aswan.

Enhanced sulfidation xanthate flotation of malachite using ammonium ions as activator
Scientific Reports, 2017 In this study, ammonium ion was used to enhance the sulfidation flotation of malachite. The effect of ammonium ion on the sulfidation flotation of malachite was investigated using microflotation test, inductively coupled plasma (ICP) analysis, zeta ...

Medicine for the Material World
Archaeometry, EarlyView.ABSTRACT It is clear that many of the inorganic materials of antiquity have been used both as medicines for human ills and also as agents in technological processes. This paper speculates that there might have been a stronger link between these two functions in the past, based on the concept of “active agents”—materials that are efficacious at curing ...

Growth, Dissolution and Segregation of Genetically Encoded RNA Droplets by Ribozyme Catalysis
Angewandte Chemie, Volume 138, Issue 7, 9 February 2026.Ribozymes enable sequence‐encoded turnover of RNA droplet material, resulting in transiently active droplets that selectively segregate based on their genotype. This establishes a direct link between genetic information and droplet behavior, marking a step toward programmable, evolvable RNA‐based compartments with life‐like properties.
