The viscosity of cytoplasm is roughly the same as pure water, although diffusion of small molecules through this liquid is about fourfold slower than in pure water, due mostly to collisions with the large numbers of macromolecules in the cytosol.

Even the structure of pure water is poorly understood, due to the ability of water to form structures such as water clusters through hydrogen bonds.

The classic view of water in cells is that about 5 % of this water is strongly bound in by solutes or macromolecules as water of solvation, while the majority has the same structure as pure water.

However, the use of advanced nuclear magnetic resonance methods to directly measure the mobility of water in living cells contradicts this idea, as it suggests that 85 % of cell water acts like that pure water, while the remainder is less mobile and probably bound to macromolecules.

In 1851, Otto Funke published a series of articles in which he described growing hemoglobin crystals by successively diluting red blood cells with a solvent such as pure water, alcohol or ether, followed by slow evaporation of the solvent from the resulting protein solution.

has a value close to 10 < sup >− 14 </ sup > at 25 ° C, so the concentration of hydroxide ions in pure water is close to 10 < sup >− 7 </ sup > mol dm < sup >− 3 </ sup >, in order to satisfy the equal charge constraint.

" For example, James Madison argued for a constitutional republic with protections for individual liberty over a pure democracy, reasoning that, in a pure democracy, a " common passion or interest will, in almost every case, be felt by a majority of the whole ... and there is nothing to check the inducements to sacrifice the weaker party ...."

Kant preferred republicanism to pure democracy, on the grounds that the latter may be the unrestricted rule of the majority, unrestrained by law.

Due to the small size of San Marino and its low population, it is difficult for any party to gain a pure majority and most of the time the government is run by a coalition.

For instance, in a 1942 lecture, published posthumously, Heidegger said of recent German classics scholarship: " In the majority of ' research results ,' the Greeks appear as pure National Socialists.

Herbert Marcuse wrote " Repressive Tolerance " in 1965 where he argued that the " pure tolerance " that permits all favors totalitaliam democraty and tyranny of majority, and insisted the " repressive tolerance " against them.

In April 1935, a volume of essays by five leading National Labour politicians was published under the title " Towards a National Policy: being a National Labour Contribution "; MacDonald contributed a preface in which he argued that the Labour opposition " is as little guided by Socialist opinion and inspired by the fine human spirit of our British Socialism as any other political party of pure expediency striving for a majority ".

In a pure ( zero-bypass ) jet engine, the majority of the thrust occurs from the high temperature and high pressure exhaust gas being accelerated by expansion through a propelling nozzle ( the lesser part of the thrust is obtained by accelerating air in the compressor stage ).

The most common purity grades required by modern instruments for the majority of sensitivities are 5. 0 grades, or 99. 999 % pure meaning that there is a total of 10ppm of impurities in the carrier gas that could affect the results.

A growing body of evidence suggests that a majority of people with celiac disease and following a gluten-free diet can safely consume pure oats in moderate amounts.

On an appeal to the Divisional Court in 1957 concerning a pure breach of the Code of Professional Conduct under the legislation then in force ( the architect was practising an estate agent's business as well as his own ), when the registration body was constituted under the name the Architects ' Registration Council of the United Kingdom, Mr Justice Devlin ruled: " It is not of itself disgraceful to disagree with a majority view and to act accordingly.

While the vast majority have completely reverted to pure animal instinct, a rare few are claimed to demonstrate the intellect and capacities of an insane human.

The majority of dental implants are made out of commercially pure titanium, which is available in 4 grades depending upon the amount of carbon and iron contained.

However, the BBC also described bugchasing as more internet fantasy than reality, saying that, " Dyer finds that the overwhelming majority of the talk is pure fantasy.

" The Federalist Papers are pervaded by the idea that pure democracy is actually quite dangerous, because it allows a majority to infringe upon the rights of a minority.

In a pure xenon lamp, the majority of the light is generated within a tiny, pinpoint-sized cloud of plasma situated where the electron stream leaves the face of the cathode.

Since the majority could be quite wrong in regard to particular issues, however, adapting to that majority opinion on those issues might, in a specific context, be an even bigger error than " keeping one's principles pure ".

Plato ’ s democracy is not the modern notion of a mix of democracy and republicanism, but rather direct democracy by way of pure majority rule.

Today the main focus of pure biochemistry is in understanding how biological molecules give rise to the processes that occur within living cells, which in turn relates greatly to the study and understanding of whole organisms.

Concurrently, molecules of B diffuse toward regimens formerly occupied by pure A.

Earlier definitions were less precise, defining molecules as the smallest particles of pure chemical substances that still retain their composition and chemical properties.

A pure substance is composed of molecules with the same average geometrical structure.

In the absence of stronger inter-species attractions between like-like or like-unlike molecules, the vapor pressure follows Raoult's Law, which states that the partial pressure of each component is the product of the vapor pressure of the pure component and its mole fraction in the mixture.

The mole is a unit of measurement used in chemistry to express amounts of a chemical substance, defined as an amount of a substance that contains as many elementary entities ( e. g., atoms, molecules, ions, electrons ) as there are atoms in 12 grams of pure carbon-12 (< sup > 12 </ sup > C ), the isotope of carbon with atomic weight 12.

, the mole is defined by BIPM to be an amount of a substance that contains as many elementary entities ( e. g. atoms, molecules, ions, electrons ) as there are atoms in 12 grams of pure carbon-12 (< sup > 12 </ sup > C ), the isotope of carbon with atomic weight 12.

Thus, by definition, one mole of pure < sup > 12 </ sup > C has a mass of exactly 12 g. It also follows from the definition that X moles of any substance will contain the same number of molecules as X moles of any other substance.

# Any pure element ( even if it forms diatomic molecules like chlorine, Cl < sub > 2 </ sub >) has an oxidation state ( OS ) of zero.

Such a deviation suggests weaker intermolecular attraction than in the pure components, so that the molecules can be thought of as being " held in " the liquid phase less strongly than in the pure liquid.

In pure water, about one in ten million molecules dissociate into hydronium ions and hydroxide ions according to the following equation:

These diamondoids occur naturally in petroleum deposits and have been extracted and purified into large pure crystals of polymantane molecules having more than a dozen adamantane cages per molecule.

The inherent scattering that radiation undergoes passing through a pure gas is due to microscopic density fluctuations as the gas molecules move around, which are normally small enough in scale for Rayleigh's model to apply.

Decoherence shows how a macroscopic system interacting with a lot of microscopic systems ( e. g. collisions with air molecules or photons ) moves from being in a pure quantum state — which in general will be a coherent superposition ( see Schrödinger's cat )— to being in an incoherent mixture of these states.

However, in real systems the interaction effects between gas molecules result in a small increase of the saturation vapor pressure of water in air relative to saturated vapor pressure of pure water vapor.

Given that Hg ( CN )< sub > 2 </ sub > molecules remain undissociated in pure water and in basic solutions, it makes sense that dissociation would increase with increasing acidity.

The osmotic pressure of a solution is the difference in pressure between the solution and the pure liquid solvent when the two are in equilibrium across a semipermeable membrane, which allows the passage of solvent molecules but not of solute particles.

Unlike other molecules, spherical top molecules have no net dipole moment, and, hence, they do not exhibit a pure rotational spectrum.
