Sentences with phrase «repel water molecules»

Weiqing Ren from the A * STAR Institute of High Performance Computing and the National University of Singapore used a «climbing string» computational technique to model a micropatterned surface that uses microfabricated pillars to trap air pockets and so repel water molecules.

But two years ago, a pair of NASA scientists levitated a mouse using a superconducting magnet that repelled the water molecules in the creature's body.

«Superhydrophobic» surfaces, such as anti-icing or self - cleaning windows, are remarkably effective at repelling water molecules.

Not exact matches

This allowed them to investigate the phenomena of hydrophilicity and hydrophobicity at the molecular level, i.e. why certain parts of organic molecules attract or repel water.

These molecules repel water at one end and attract it at the other, properties that cause them to self - assemble into spherical structures, which can encapsulate large payloads of biological molecules.

Alternating water - repelling and water - attracting parts of the protein tug nearby water molecules into an orderly, icelike arrangement.

With one end attracted to water and the other end repelled by it, the surfactant molecules travel to the surface of the drop once it is immersed in oil.

The super-hydrophilic coatings can also be made to do exactly the opposite and become «super-hydrophobic» — water - fearing, by adding a second, ultra-thin layer of water - repelling molecules.

In water solution, the combination of DNA, which is attracted to water molecules, and lipids, which are repelled by water, causes the Y units to self - assemble into hollow spheres from 100 to 5,000 nanometers in diameter, consisting of multiple layers of DNA, lipid and cargo.

A new molecule, nicknamed EH44 and developed by Alan Sellinger at the Colorado School of Mines, was incorporated as a replacement to spiro - OMeTAD because it repels water and doesn't contain lithium.

This means instead of dissolving in water, fats and oils «repel» water molecules (actually, it's more of a lack of attraction).

Fats, also known as lipids, are a diverse group of molecules with a «non-polar» characteristic that repels water.
