DNA-Based Chemical Unclonable Functions for Cryptographic Anticounterfeit Tagging of Pharmaceuticals.

Counterfeit products are a problem known across many industries. Chemical products such as pharmaceuticals belong to the most targeted markets, with harmful consequences for consumer health and safety. However, many of the currently used anticounterfeit measures are associated with the packaging, with the readout method and level of security varying between different solutions.

Outbreak simulation on the neonatal ward using silica nanoparticles with encapsulated DNA: unmasking of key spread areas.

Background: Nosocomial infections pose a serious threat. In neonatal intensive care units (NICUs) especially, there are repeated outbreaks caused by micro-organisms without the sources or dynamics being conclusively determined.

Aim: To use amorphous silica nanoparticles with encapsulated DNA (SPED) to simulate outbreak events and to visualize dissemination patterns in a NICU to gain a better understanding of these dynamics.

The environmental sustainability of digital content consumption.

Internet access has reached 60% of the global population, with the average user spending over 40% of their waking life on the Internet, yet the environmental implications remain poorly understood. Here, we assess the environmental impacts of digital content consumption in relation to the Earth's carrying capacity, finding that currently the global average consumption of web surfing, social media, video and music streaming, and video conferencing could account for approximately 40% of the per capita carbon budget consistent with limiting global warming to 1.5 °C, as well as around 55% of the per capita carrying capacity for mineral and metal resources use and over 10% for five other impact categories.

Low-nuclearity CuZn ensembles on ZnZrO catalyze methanol synthesis from CO.

Metal promotion could unlock high performance in zinc-zirconium catalysts, ZnZrO, for CO hydrogenation to methanol. Still, with most efforts devoted to costly palladium, the optimal metal choice and necessary atomic-level architecture remain unclear. Herein, we investigate the promotion of ZnZrO catalysts with small amounts (0.
