Optimizing non-Newtonian fluids for impact protection of laminates.
Proc Natl Acad Sci U S A
March 2024
Non-Newtonian fluids can be used for the protection of flexible laminates. Understanding the coupling between the flow of the protecting fluid and the deformation of the protected solids is necessary in order to optimize this functionality. We present a scaling analysis of the problem based on a single coupling variable, the effective width of a squeeze flow between flat rigid plates, and predict that impact protection for laminates is optimized by using shear-thinning, and not shear-thickening, fluids.

Spillage may result in under-dosing and poor sensory properties can lead to under-utilisation. We first propose four principles (low runoff, spreadability, smoothness and non-stickiness) for designing the rheology of thickened alcohol-based hand rubs with acceptable handleability and hand feel.

- Much of the science behind the global response to COVID-19 relates to soft matter, specifically the structure of coronaviruses and their transmission routes.
- Coronaviruses consist of nucleic acids and proteins enclosed in a lipid bilayer, primarily spreading through airborne droplets and aerosols.
- There are significant gaps in our understanding of how these viruses interact with biological and artificial surfaces, which is crucial for improving infection control measures and preparing for future pandemics.
Article Synopsis
- Mixing certain powders with liquids to make strong mixtures is important in factories.
- Researchers looked at how mixing chocolate works by using special techniques to make it smoother and easier to flow.
- They found that using energy and adding special helpers (surfactants) in steps helps the chocolate mixture hold more solid content without getting stuck.
