The drops become superheated and negatively charged
, which creates ideal conditions for making nanoproducts, researchers demonstrate October 29 in Nature Communications.
Each of the PLGA nanoparticles is given either a positively charged coating made of chitosan (a biocompatible material normally found in shrimp shells), or a negatively charged
coating made of alginate (a biocompatible material normally found in seaweed).
The method is comprised of attaching a reactive group X--Y to a surface of a pigment; and subsequently displacing Y with an organic substrate N--S--ZM to form a surface-modified pigment having attached X--N--S--ZM; wherein X is a sulfonyl, phosphoryl, or 1,3,5-triazine group; Y is fluorine, chlorine, bromine or iodine; N is an amine, an imine, a pyridine, or a thiol group; S is substituted or unsubstituted alkyls, aryls, or polymer chains having a molecular weight range from approximately 300-8000; Z is a carboxyl, sulfonyl, phenolic, phosphoryl, ammonium, trimethylammonium, or tri-butylammonium group; and M is a halide, a negatively charged
ion, a proton n salt form, or a cation in salt form.
Atoms normally consist of positively charged nuclei and negatively charged
The solar wind is a thin gas of electrically charged components of atoms - negatively charged
electrons and positively charged ions -- that is constantly blowing from the surface of the sun into space.
The IonX Base Layer system - effectively a shirt worn over under garments - comes in two types, depending on whether the playing conditions are hot or cold, and uses a state-of-theart ionised energy fabric which ionises the body through a negatively charged
The experimental cooling device, fabricated on top of a mock computer chip, works by generating ions using negatively charged
cathodes and a positively charged anode positioned above the cathodes.
Casein and soy proteins were negatively charged
with ZP before they were heated.
The Stablo EX two-way ionizer is said to generate a balanced mix of positively and negatively charged
ions that eliminate static on laboratory samples, allowing them to be weighed accurately with high repeatability, according to the company.
Particles called--flow from a negatively charged
area in a cloud to a positively charged area to form lightning.
As the spray is atomized, the negatively charged
droplets are carried in an air stream toward the target.
particles gaths of the cloud tively charged that are negatively charged
gather at the The cloud circuit and created as flashes from top to bottom.
