pin point accuracy
squeeze (n.) 1610s, "act of squeezing," from squeeze (v.). Main squeeze "most important person" is attested from 1896; meaning "one's sweetheart, lover" is attested by 1980. Slang expression to put the squeeze on (someone or something) "exert influence on" is from 1711.
A lover?
There are only two types of charge, one called positive and the other called negative. Like charges repel, whereas unlike charges attract. The force between charges decreases with distance.
If you describe a dispute or a legal case as open-and-shut, you mean that is easily decided or solved because the facts are very clear. It's an open-and-shut case.
if you squeeze or stretch a piezoelectric crystal, you deform the structure, pushing some of the atoms closer together or further apart, upsetting the balance of positive and negative, and causing net electrical charges to appear.
early 13c., pinchen, "to pluck (an eyebrow);" mid-14c. "compress between the finger and thumb or some device, squeeze between two hard, opposing bodies," from Old North French *pinchier "to pinch, squeeze, nip; steal" (Old French pincier, Modern French pincer), a word of uncertain origin, possibly from Vulgar Latin *punctiare "to pierce," which might be a blend of Latin punctum "point" + *piccare "to pierce."

Middle English: from Old French percer, based on Latin pertus- ‘bored through’, from the verb pertundere, from per ‘through’ + tundere ‘thrust’.
[i′lek‚trän ′tən·əl·iŋ] (quantum mechanics) The passage of electrons through a potential barrier which they would not be able to cross according to classical mechanics, such as a thin insulating barrier between two superconductors.
Tunneling is a quantum mechanical effect. A tunneling current occurs when electrons move through a barrier that they classically shouldn't be able to move through. In classical terms, if you don't have enough energy to move “over” a barrier, you won't. ... Tunneling is an effect of the wavelike nature.
Phase-shift masks are photomasks that take advantage of the interference generated by phase differences to improve image resolution in photolithography. There exist alternating and attenuated phase shift masks. A phase-shift mask relies on the fact that light passing through a transparent media will undergo a phase change as a function of its optical thickness.
An attenuated vaccine is a vaccine created by reducing the virulence of a pathogen, but still keeping it viable.
Atomization refers to the process of breaking up bulk liquids into droplets.
Liquid atomization is applied in nanostructure dense coating technology to inject suspended nano-size powder materials into a suspension plasma spray (SPS) torch. This paper presents the effects of the atomization parameters on the nanoparticle processing. A numerical model was developed to simulate the dynamic behaviors of the suspension droplets, the solid nanoparticles or agglomerates, as well as the interactions between them and the plasma gas. The plasma gas was calculated as compressible, multi-component, turbulent jet flow in Eulerian scheme. The droplets and the solid particles were calculated as discrete Lagrangian entities, being tracked through the spray process. The motion and thermal histories of the particles were given in this paper and their release and melting status were observed.
The key parameters of atomization, including droplet size, injection angle and velocity were also analyzed. The study revealed that the nanoparticle processing in SPS preferred small droplets with better atomization and less aggregation from suspension preparation. The injection angle and velocity influenced the nanoparticle release percentage. Small angle and low initial velocity might have more nanoparticles released. Besides, the melting percentage of nanoparticles and agglomerates were studied, and the critical droplet diameter to ensure solid melting was drawn.
Results showed that most released nanoparticles were well melted, but the agglomerates might be totally melted, partially melted, or even not melted at all, mainly depending on the agglomerate size. For better coating quality, the suspension droplet size should be limited to a critical droplet diameter, which was inversely proportional to the cubic root of weight content, for given critical agglomerate diameter of being totally melted.
A new residual-free atomizer was designed to transfer colloidal nanoparticles measuring less than 100 nm into aerosol phase.
