Video: Silica, a common food additive, may be chemically reactive

By Lisa McDonald / September 27, 2023

The increasing use of nanoparticles across all sectors has led to some concerns within the food industry, as nanoparticles do not necessarily behave the same way as their larger counterparts. A new study by Stanford University researchers showed that mesoporous silica, a common food additive, can react with key biomolecules, which could lead to increased oxidative stress in the body.

Foiled no more: A review of advancements in producing carbon nanotubes on flexible metal substrates

By Lisa McDonald / August 8, 2023

Growing carbon nanotubes on metal foils rather than traditional silicon or quartz substrates would allow the process to be easily integrated into large-scale manufacturing processes. But metal foils present other challenges, such as reactivity at high temperatures. Lawrence Livermore National Laboratory researchers published a review paper summarizing efforts to overcome these challenges.
