Product Name: Ag Nanoparticles Aqueous Dispersion

Silver Ag Dispersion Description :

There are many ways silver nanoparticles can be synthesized; one method is through monosaccharides. This includes glucose, fructose, maltose, maltodextrin, etc., but not sucrose.

Ag Nanoparticles Aqueous Dispersion is also a simple method to reduce silver ions back to silver nanoparticles as it usually involves a one-step process. There have been methods that indicated that these reducing sugars are essential to the formation of silver nanoparticles.

Many studies indicated that this method of green synthesis, specifically using Cacumen platycladi extract, enabled the reduction of silver. Additionally, the size of the nanoparticle could be controlled depending on the concentration of the extract. Ag Nanoparticles Aqueous Dispersion that the higher concentrations correlated to an increased number of nanoparticles.

Smaller nanoparticles were formed at high pH levels due to the concentration of the monosaccharides. Another method of silver nanoparticle synthesis includes the use of reducing sugars with alkali starch and silver nitrate.

The reducing sugars have free aldehyde and ketone groups, which enable them to be oxidized into gluconate. The monosaccharide must have a free ketone group because to act as a reducing agent it first undergoes tautomerization. Besides, if the aldehydes are bound, it will be stuck in cyclic form and cannot act as a reducing agent.

For example, glucose has an aldehyde functional group that can reduce silver cations to silver atoms and is then oxidized to gluconic acid. The reaction for the sugars to be oxidized occurs in aqueous solutions.

The capping agent is also not present when heated.The growth of nanoseeds involves placing the seeds into a growth solution. The growth solution requires a low concentration of a metal precursor, ligands that will readily exchange with preexisting seed ligands, and a weak or very low concentration of reducing agent. The reducing agent must not be strong enough to reduce metal precursors in the growth solution in the absence of seeds.

Otherwise, the growth solution will form new nucleation sites instead of growing on preexisting ones (seeds). Growth is the result of the competition between surface energy (which increases unfavorably with growth) and bulk energy (which decreases favorably with growth).

The balance between the energetics of growth and dissolution is the reason for uniform growth only on preexisting seeds (and no new nucleation). Growth occurs by the addition of metal atoms from the growth solution to the seeds, and ligand exchange between the growth ligands (which have a higher binding affinity) and the seed ligands.

The range and direction of growth can be controlled by nano speed, the concentration of metal precursor, ligand, and reaction conditions (heat, pressure, etc.). Controlling stoichiometric conditions of growth solution controls the ultimate size of the particle. For example, a low concentration of metal seeds to metal precursors in the growth solution will produce larger particles.

Capping agent has been shown to control the direction of growth and thereby shape. Ligands can have varying affinities for binding across a particle. Differential binding within a particle can result in dissimilar growth across particles. This produces anisotropic particles with nonspherical shapes including prisms, cubes, and rods.

Aluminum Silver Nanopowder Dispersion

Aluminum-Silver Nanopowder Dispersion Description  :

Nanofluids have novel properties that make them potentially useful in many applications in heat transfer, including microelectronics, fuel cells, pharmaceutical processes,

Hybrid-powered engines, engine cooling/vehicle thermal management, domestic refrigerator, chiller, heat exchanger, in grinding, machining, and in boiler flue gas temperature reduction.

They exhibit enhanced thermal conductivity and the convective heat transfer coefficient compared to the base fluid. Knowledge of the rheological behavior of nanofluids is found to be critical in deciding their suitability for convective heat transfer applications.

Nanofluids also have special acoustical properties and in ultrasonic fields display additional shear-wave reconversion of an incident compressional wave; the effect becomes more pronounced as concentration increases.

An analysis such as computational fluid dynamics, nanofluids can be assumed to be single-phase fluids. However, almost all new academic papers use a two-phase assumption. The classical theory of single-phase fluids can be applied, where the physical properties of nanofluid are taken as a function of properties of both constituents and their concentrations. An alternative approach simulates nanofluids using a two-component model.

Aluminum Silver Nanopowder Dispersion spreading of a nanofluid droplet is enhanced by the solid-like ordering structure of nanoparticles assembled near the contact line by diffusion.

Which gives rise to a structural disjoining pressure in the vicinity of the contact line. However, such enhancement is not observed for small droplets with a diameter of nanometer scale, because the wetting time scale is much smaller than the diffusion time scale.

Chromium Erbium Oxide Dispersion is also used a thermal spray material for protecting the underlying metal surface, and as an additive to corrosion-resistant and wear-resistant materials. chromium Erbium Oxide Dispersionare used in coatings of bearings, seals, orifices, and valve seals The corundum structure, consisting of a hexagonal close-packed array of oxide anions with ​2⁄3 of the octahedral holes occupied by chromium. Similar to corundum, Cr 2O3 is a hard, brittle material (Mohs hardness 8 to 8.5). It is antiferromagnetic up to 307 K, the Néel temperature.

Chromium Erbium Oxide Dispersion is not readily attacked by acids. Because of its considerable stability, chromium is a commonly used pigment. It was originally called viridian. It is used in paints, inks, and glasses. It is the colorant in "chrome green" and "institutional green." Chromium Erbium Oxide Dispersion is a precursor to the magnetic pigment chromium dioxide, by the following reaction. Along with many other oxides.

Chromium Erbium Oxide Dispersion is used as a compound when polishing (also called stropping) the edges of knives, razors, surfaces of optical devices, etc. on a piece of leather, balsa, cloth, or other material. It is available in powder or wax form, and in this context, it is known as "green compound". Unlike the classic thermite reaction involving iron oxides,

The chromium oxide thermite creates few or no sparks, smoke, or sound, but glows brightly. Because of the very high melting point of chromium, chromium thermite casting is impractical. Heating with chlorine and carbon yields chromium chloride and carbon monoxide.

Chromium Propylene Glycol Dispersion

Chromium Propylene Glycol Dispersion Description:

Chromium Propylene Glycol Dispersion according to the National Library of Medicine and Agency for Toxic Substances and Disease Registry, is a synthetic liquid substance that absorbs water. It is labeled an organic compound in chemistry due to its carbon attributes. It is a viscous, colorless liquid, which is nearly odorless but possesses a faintly sweet taste. Containing two alcohol groups, it is classed as a diol.

Chromium Propylene Glycol Dispersion miscible with a broad range of solvents, including water, acetone, and chloroform. In general, glycols are non-irritating and have very low volatility. It is produced on a large scale primarily for the production of polymers. Propylene glycol is approved and used as a vehicle for topical, oral, and some intravenous pharmaceutical preparations. Final products contain 20% propylene glycol, 1.5% of di propylene glycol, and small amounts of other Chromium Propylene Glycol Dispersion. Further purification produces finished industrial grade or USP/JP/EP/BP grade propylene glycol that is typically 99.5% or greater. Use of USP (US Pharmacopoeia) propylene glycol can reduce the risk of Abbreviated New Drug Application (ANDA) rejection.

Chromium Propylene Glycol Dispersion can also be obtained from glycerol, a byproduct of the production of biodiesel. This starting material is usually reserved for industrial use because of the noticeable odor and taste that accompanies the final product.

Copper Oxide Nanopowder Dispersion

Copper Oxide Dispersion Description

Copper Oxide Water Dispersion antifungal/antibacterial activities that are not observed in commercial copper. First of all, copper nanoparticles demonstrate a very strong catalytic activity, a property that can be attributed to their large catalytic surface area. With the small size and great porosity.

The nanoparticles are able to achieve a higher reaction yield and a shorter reaction time when utilized as reagents in organic and organometallic synthesis. In fact, copper nanoparticles that are used in a condensation reaction of iodobenzene attained about 88% conversion to biphenyl, while the commercial copper exhibited only a conversion.

Copper Oxide Water Dispersion that is extremely small and has a high surface to volume ratio can also serve as an antifungal/antibacterial agents. The antimicrobial activity is induced by their close interaction with microbial membranes and their metal ions released in solutions.

Copper Oxide Water Dispersion slowly in solutions, cupric ions are released from them and they can create toxic hydroxyl free radicals when the lipid membrane is nearby.  Copper Oxide Water Dispersion radicals disassemble lipids in cell membranes through oxidation to degenerate the membranes. As a result, the intracellular substances seep out of cells through the destructed membranes.

The cells are no longer able to sustain fundamental biochemical processes. In the end, all these alterations inside of the cell caused by the free radicals lead to cell death.

Copper Oxide Water Dispersion with great catalytic activities can be applied to biosensors and electrochemical sensors. Redox reactions utilized in those sensors are generally irreversible and also require high overpotentials (more energy) to run. In fact, the nanoparticles have the ability to make the redox reactions reversible and to lower the overpotentials when applied to the sensors.
