Brownian Motion of Suspended Solids and Supporting Theories

Brownian Motion in Chemistry Nano science and Nanotechnology

Brownian motion is essentially important to assist in various chemical reactions. It has a huge role in thermal conductivity, and nanoscience, and nanotechnology. For the past few decades, engineers, scientists, and researchers are trying their best to develop fluids offering better heating and cooling performance and properties.

Brownian motion is the erratic movement of particles suspended in a fluid (gas or liquid) resulting from their collision with molecules of the suspending fluid. Brownian motion was first observed by Robert Brown in 1827 using pollen grains.

Brown’s observation was an accident during his botanical investigations. And this phenomenon became known as Brownian motion due to Brown’s observation of pollen colliding with microscopic objects.

While many people are concerned about which investigator is credited for discovering Brownian motion. Its a long story and has been explained in our recent articles

Nanofluids and Thermal Engineering

Nanofluids are classified as heat transfer fluids that are specifically engineered. By the dispersion of nanometer range solid particles in the specific conventional fluid tubes, rods, and particles such as engine oil and water. This field is interdisciplinary and is rapidly emerging due to the use of modern technologies such as thermal engineering, nanotechnology, and nanoscience.

This research area has gained significant attention from researchers and scientists due to exciting properties and novel applications in advanced fields such as medical, manufacturing, transportation, agriculture, microfluidics, and microelectronics.

Dispersion of Nanoparticles

Proper dispersion of nanoparticles in the nanofluids offers various benefits such as reduced requirements of pumping power. Improved heat stability, and heat transfer, microchannel cooling with no clogging, and miniaturized systems. Nanofluids offer better stability and thus offer reduced clogging. Moreover, it offers prevention of rapid settling in the heat transfer causing devices.

Potential Role of Brownian Motion for Nanofluids and Nanotechnology Applications

This phenomenon is completely resulting due to innumerable collisions of particles. If particles are having small inertia due to their smaller size, then the individual collision forces are enough for internal movement. Sometimes, particles can hit a specific site more than any other site and thereby causing seemingly random motion.

This motion will not cause net changes in the concentration if the suspension or solution is uniform. But if there is nonuniformity in the concentration it can cause equalization of concentration.  Brownian motion and stochastic calculus are greatly helpful for numerous applications in different sectors.

Modern scientific research has also enabled researchers to explain what causes the Brownian motion of particles in a colloid, Brownian motion stimulation, integral of Brownian motion, Brownian motion diffusion, and Brownian motion with drift.

The immersion of submicron structures and particles in the water. Any liquid medium is subject to continuous interaction or bombardment from numerous molecules present around them. This bombardment causes their movement and internal flex in uncontrollable ways and random directions. Nanodevices, nanofluids, nanoparticles, and other nanostructures are now offering a wide range of applications in almost all sectors.
