ions造句
Smaller sodium ions leave the glass, and larger potassium ions from the salt bath replace them.
In solution, this detergent creates negative ions, which cut grease.
This functioned as a selective bridge, permitting the passage of positively charged sodium ions, but not negatively charged chloride ions.
Histidine likes to bind tightly to zinc ions.
The ions that pass through the field generate thrust.
By pumping positively charged potassium and sodium ions out of the cell, the number of negatively charged ions inside the cells rises.
Shielded from the buffeting of the solar wind, ions quietly leak out of the atmosphere.
In one cubic centimeter of air there are about 2, 000 ions.
A battery's electrolyte is the material through which ions (in this case lithium ions) pass from one electrode (the cathode) to another (the anode) inside a battery cell.
When carbon dioxide dissolves in seawater, the concentration of hydrogen ions increases, making it more acidic.
Formation constants of complex ions also are of widely varying accuracy.
Electrons are small and mobile but lithium ions are much larger and slower.
The action of calicium as a protective agent against inimical ions is not a highly specific function.
Prior attempts to control ions by charging the surfaces of microfluidic channels, however, showed that ions quickly migrated to channel walls and canceled out the voltage, shielding the rest of the liquid from further electric manipulation.
Two electrodes flanking the system of channels then create a voltage that pulls positively charged ions such as sodium in one direction and negatively charged ions such as chloride in the other.
In 1967 researchers at the Ford Motor Company discovered that it conducts these ions as though it were a liquid.
But the NIST group was able to entangle the mechanical motion of two sets of vibrating ions.
Charged particles called ions travel along the nanowire, causing it to stretch out in length and also bend and wiggle.
Electrolytes are simply salt ions that are used by cells to move fluids and nerve messages into and out of cells throughout the body.
Plasmas are gases in which the molecules have been stripped of some or all of their electrons, to create positive ions.
Cronin says early results suggest he can create a membrane that splits water into hydrogen ions, electrons and oxygen when illuminated - the initial step of photosynthesis.
In an ultracapacitor, the distance between the ions and opposite-charged electrode is so tiny it's measured in nanometers (one-thousandth of a micron).
A chelating agent that softens hard tap water by binding with dissolved metal ions, preventing them from being deposited as a yucky residue on your nice clean dishes.
And, what we will do next day is we will look at the consequences of such an energetic set up, and rationalize that when ions form, by necessity we must form ionic crystals.
They exposed one side of their porous carbon electrode to an electrolyte rich in lithium ions and put a mesh window on the other side of the electrode through which air could be drawn.
The answer to that is definitely no -- if they had the same electron configuration, they would, in fact be neon. But we can think about different ions that have this electron configuration.
"particle accelerator : Device that accelerates a beam of fast-moving, electrically charged atoms (ions) or subatomic particles. Accelerators are used to study the structure of atomic nuclei and the nature of subatomic particles and their fundamental interactions."
Experience has shown that writing assert ions while programming is one of the quickest and most effective ways to detect and correct bugs.以往经验已显示在写程序同时写断言是迅速和最有效察觉和校正臭虫的方式之一.
This paper reviews the corrosion resistance of various dental alloys evaluated in the light of their released ions in experiments, and shows the examples in which original corrosion resistance is lowered by the factors such as casting, polishing and contact with other metals.
