This leaves one to share with one of its two neighboring carbon atoms, which is why the benzene molecule is drawn with alternating single and double bonds around the hexagon.

This results in a single SWNT that acts as a NOT logic gate with both p and n-type FETs within the same molecule.

That system can be a single molecule, a group of molecules, or a solid.

A single atom of the original molecule may appear in many places ( some as ghosts, some not ) in the tree.

In living organisms DNA does not usually exist as a single molecule, but instead as a pair of molecules that are held tightly together.

< u > Top :</ u > A single molecule moves around randomly.

It is not a coincidence that this happens in the " visible range ," as the mechanism of vision involves the change in bonding of a single molecule ( retinal ) which absorbs light in the rhodopsin the retina of the human eye.

Photosynthesis becomes possible in this range as well, for similar reasons, as a single molecule of chlorophyll is excited by a single photon.

Animals which detect infrared do not use such single molecule processes, but are forced to make use of small packets of water which change temperature, in an essentially thermal process that involves many photons ( see infrared sensing in snakes ).

The energy of formation of a molecule containing only single bonds then can be approximated from an electronegativity table, and depends on the constituents and sum of squares of differences of electronegativities of all pairs of bonded atoms.

Since ortho derivatives of benzene were never actually found in more than one isomeric form, Kekulé modified his proposal in 1872 and suggested that the benzene molecule oscillates between two equivalent structures, in such a way that the single and double bonds continually interchange positions .< ref >

< u > Top :</ u > A single molecule moves around randomly.

A portions of a DNA molecule that specifies a single functional unit is called a gene ; different genes have different sequences of bases.

It possesses a regular crystalline structure based on the molecule of water, which consists of a single oxygen atom covalently bonded to two hydrogen atoms, or H-O-H.

While he usually does not use his powers in lethal ways his powers are so vast that it extends to the molecular level, to the point that he can freeze all of the molecules of an object / being with a thought ; he once froze every single molecule of water within the body of David Haller.

Each ion is typically a single atom or molecule, and thus the actual amount of material implanted in the target is the integral over time of the ion current.

The postulated potential energy of a single molecule is given by:

Notably, this doesn ’ t release single copies of the phage genome, but rather one long molecule with many copies of the genome: a concatemer.

In G < sub > 1 </ sub > stage each of the chromosomes consists of a single ( very long ) molecule of DNA.

A molecule may consist of atoms of a single chemical element, as with oxygen ( O < sub > 2 </ sub >), or of different elements, as with water ( H < sub > 2 </ sub > O ).

A stricter interpretation does not equate the two, as the mass of a single molecule is not the same as the average of an ensemble.

Because a mole of molecules may contain a variety of molecular masses due to natural isotopes, the average mass is usually not identical to the mass of any single molecule.

The use of average atomic masses derived from the standard atomic weights found on a standard periodic table will result in an average molecular mass, whereas the use of isotopic masses will result in a molecular mass consistent with the strict interpretation of the definition, i. e. that of a single molecule.

" Many installations have reported that a reflective or light colored dome induces a local vertical heat driven vortex that sucks cooler overhead air downward into a dome if the dome is vented properly ( a single overhead vent, and peripheral vents ).

# In one single event, the saved who are alive at Christ's coming will be caught up together with the resurrected to meet the Lord in the air.

Laws dealing with pollution are often media-limited — i. e., pertain only to a single environmental medium, such as air, water ( whether surface water, groundwater or oceans ), soil, etc .— and control both emissions of pollutants into the medium, as well as liability for exceeding permitted emissions and responsibility for cleanup.

* The Haynes Aero Skyblazer is a development stage vehicle that uses a single turbofan engine to provide thrust in the air and to generate electricity to power electric motors for ground travel.

The number of rotations performed in the air for each jump determines whether the jump is a single, double, triple, or quadruple ( known commonly as a " quad ").

At times a song will be sung or a slow air played by a single musician between sets.

Many modern kayaks have modified the traditional design in various ways, such as: eliminating the cockpit by seating the paddler on top of the boat (" sit-on-top " kayaks ); having inflated air chambers surrounding the boat ; replacing the single hull by twin hulls (" W " kayak ), and replacing paddles with other human powered propulsion methods, such as foot-powered rotational propellers and ' flippers '.

After the Gulf War, Qatar's air force infrastructure was upgraded by France for $ 200 million, leading to the order of nine single Mirage 2000-5DEA multi-role combat aircraft and three two seat Mirage 2000-5DDA combat trainers in August 1994.

The music video for the single " Rock Box " was the first ever rap video to air on MTV and received heavy rotation from the channel.

This was literally true only of the " Monosoupape " ( single valve ) type in which the air supply was taken in through the exhaust valve, and so could not be controlled via the crankcase intake.

Though a single shell could have disastrous local effect, the guns were susceptible to air attack in addition to being slow to move.

Each single player track is littered with coins and power up tiles, as well as turbo tiles which give the karts a boost of speed and jumps which launch the karts into the air.

Two of the air force's U. S .- based war-fighting commands, SAC and Tactical Air Command ( TAC ), were reorganized into a single organization, Air Combat Command ( ACC ).

* free-diving-swimming underwater on a single breath of air.

Modern recreational rigs most often have two regulators connected to a single cylinder, in case the primary regulator fails or another diver runs out of air.

Other cuts included the reduction of multiple gunshot impacts into Gamble's feet in the morgue down to a single hit ; a close-up of his screaming face as the air conditioner falls onto him ; a sound cut to Mason snapping a Marine's neck and two bloody gunshot wounds ( to Hummel and Baxter ), both near the end of the film.

He was an eclectic philosopher who adopted many principles of the Milesian school, especially the single material principle, which he identified as air ( aether ).

The single military confrontation of the " war " ended with a report of shots being fired into the air, incurring no casualties.

Rice's experimental single stage system's working fluid was air.

Lexical words are somewhat rarer in English and are generally restricted to a single syllable: eye, awe, owe, and in non-rhotic accents air, ore, err.

Most production carbureted ( as opposed to fuel-injected ) engines have a single carburetor and a matching intake manifold that divides and transports the air fuel mixture to the intake valves, though some engines ( like motorcycle engines ) use multiple carburetors on split heads.

Another is disc brakes fade less when hot, and in a heavy vehicle air and rolling drag and engine braking are small parts of total braking force, so brakes are used harder than on lighter vehicles, and drum brake fade can occur in a single stop.

The Operation Meetinghouse air raid of 9 – 10 March 1945 was later estimated to be the single most destructive bombing raid in history.

The Operation Meetinghouse firebombing of Tokyo on the night of 9 / 10 March 1945 was the single deadliest air raid of World War II ; greater than Dresden, Hiroshima, or Nagasaki as single events.
