Native polyacrylamide gels PubMed
Abstract. Usually proteins are separated by polyacrylamide gel electrophoresis (PAGE) in the presence of a detergent and under (heat-) denaturing and (non- or) reducing conditions. The most commonly used detergent is sodium dodecyl sulfate (SDS). The major function of SDS is to shield the respective charge of the proteins present in the mixture

US4605689A Preparation of aqueous polyacrylamide
A process is disclosed for converting polyacrylamide gel into dilute aqueous solutions suitable for use in secondary oil recovery. Polyacrylamide gel is initially converted into a slurry of small gel particles in water from which forms a homogeneous solution concentrate which is then readily diluted to give the final drive fluid without any significant polymer

Core-Shell Nanostructure-Enhanced Raman Spectroscopy
In summary, core-shell nanostructure-enhanced Raman spectroscopies are shown to greatly boost the application of SERS in catalysis, from model systems like single-crystal surfaces to practical nanocatalysts, liquid-solid interfaces to gas-solid interfaces, and electrocatalysis to heterogeneous catalysis to photocatalysis.

The nanostructure is ideal for the stress concentration and increasing the non-uniformity of strains, thus leading to strain gradients inversely proportional to the feature size. A force as low as 400 nN is applied to generate the internal electric field in response to strain gradients and switch polarization state of each memory unit.
