Nanoparticle-coated sponge removes lead from water
May 11, 2023 (Nanowerk News) Northwestern University engineers have developed a new sponge that can remove metals — including toxic heavy metals like lead and critical metals like cobalt — from contaminated water, leaving safe, drinkable water behind. In proof-of-concept experiments, the researchers tested their new sponge on a highly contaminated sample of tap water,…

Getting a grip: Reversible perspiring artificial ‘fingertips’
May 11, 2023 (Nanowerk Spotlight) Sweating fingertips are a key characteristic that has played a critical role in human survival and evolution. Human fingertips are unique in their design and functionality, characterized by distinct patterns and the ability to perspire. These attributes have significantly contributed to our species’ survival and success over time. They have…

Bacteria killing material could tackle hospital superbugs
Credit: Pixabay/CC0 Public Domain Researchers have used a common disinfectant and antiseptic to create a new antimicrobial coating material that effectively kills bacteria and viruses, including MRSA and COVID-19. Scientists at the University of Nottingham’s School of Pharmacy took chlorhexidine, often used by dentists to treat mouth infections and for pre-surgical cleaning, and used it…

a sweet solution for overcrowded circuitry in quantum computer chips
May 11, 2023 (Nanowerk News) The silicon microchips of future quantum computers will be packed with millions, if not billions of qubits – the basic units of quantum information – to solve the greatest problems facing humanity. And with millions of qubits needing millions of wires in the microchip circuitry, it was always going to…

In vivo metallophilic self-assembly of a light-activated anticancer drug
Synthesis and characterization of a light-sensitive DSDS As in the padeliporfin photosensitizer recently approved for clinical photodynamic therapy (PDT)25, the PdL small molecule (Fig. 1a) contains a palladium(ii) metal centre. In contrast with padeliporfin, however, PdL is a bis-cyclometalated palladium compound characterized by the presence of two Pd–C covalent bonds (see Fig. 1b and full…

Mapping nanocrystalline disorder within an amorphous metal–organic framework
Mapping the nanocomposite structure SED measurements were carried out on identical Fe-BTC and MIL-100 materials as reported previously32. The samples were first assessed by examining the particle size and shape. As a 4D-STEM variant, the SED technique enables the reconstruction of virtual annular dark field (ADF) STEM images. With a field of view of ~3 μm…
