But synthetic products like gel and acrylic have environmental and human health impacts. Acrylic nails combine a liquid monomer and a powder polymer. Both of are petroleum-based and non-biodegradable.

Porath and Flodin 1 have shown that macromolecules in aqueous solutions may be separated from low molecular weight compounds by liquid chromatography using a cross-linked dextran (‘Sephadex ...

The effect of surfactant, VOC, monomer(s) type, and ratio has a great ... In this research, we synthesized polymer microcapsules loaded with different VOCs and investigated their emission properties.

The base polymer is prepared by thermal free-radical copolymerization of divinylbenzene (DVB) and 4-dimethylaminomethylstyrene (DMAMS) with nominal ratios of 25, 10, and 2.5 wt % DVB. These ...

Their value comes from diverse properties that are largely determined by their monomers—the single chemical units—that make up a polymer. Unfortunately, it can be challenging to control the ...

If you have tried out a liquid foundation or tinted moisturizer and not fallen in love with the texture or coverage, you might want to opt for a powder foundation. The best powder foundations for ...

An expert explains the chemical differences between the major detergent categories of 'liquid detergent' and 'powder detergent' and the advantages of each. What's the difference between liquid and ...

Researchers' new polymer strategy shifts a centuries-old engineering paradigm with a molecular design that doesn't sacrifice stretchability for stiffness. Researchers at the University of Virginia ...
