About Aluminum Nanoparticles Nano Al Powder:
In recent years, as potential applications in many fields have become more and more obvious, nano-aluminum powder has attracted extensive research interest. Nano aluminum powder particles appear in the form of spherical gray or black particles and are aggregated together in the form of gray or black powder, and the size is usually 10nm to 5um.
Aluminum nano-powder improves the sintering process of ceramics, has higher heat transfer performance, higher density, and improves the thermal conductivity of the sintered body, and has good sintering ability and sunlight.
 
Aluminum nanopowders add aluminum (AI) to lead selenide (PbSe), and in the past few decades, the n-type PbSe thermoelectric material thermoelectric (TE) materials and devices produced have attracted people’s attention because they The combination of solar energy and waste to convert heat into electricity has potential application value. The performance of thermoelectric materials depends on electrical conductivity, absolute temperature, lattice thermal conductivity and electronic thermal conductivity.
 
Aluminum nano-powder can be used as an environmentally friendly generator, a highly reliable and accurate temperature controllable refrigerator electronic device. Because it is one of the simplest energy conversion technologies, it can be used for electrical energy conversion. Widespread concern. The thermoelectric efficiency depends on the basic characteristics of thermoelectric materials and the quality factor of thermoelectric materials. For centuries, because the thermoelectric effect can realize the direct conversion between thermal energy and electrical energy, thermoelectric materials have attracted widespread attention, thereby providing another method of power generation and cooling.
 
The Seebeck coefficient of aluminum nanopowder is a parameter that measures the efficiency of a material to generate a voltage from a specific temperature gradient. The effect of aluminum nanoparticles on the Seebeck coefficient of silicon-based thermoelectric generators was studied. This application is partly due to the inability to obtain effective thermoelectric materials and partly due to the high power required by biomedical equipment. Feel free to send an inquiry to get the latest price if you would like to buy Aluminum Nanoparticles Nano Al Powder in bulk.

About Copper Nanoparticles Nano Cu Powder:
Ultrafine copper powder is made of nanomaterials with superplastic ductility. It’s a pure substance. Articles made of nanomaterials have many strange properties. Nano-copper, for example, is superplastic and can stretch more than 50 times at room temperature without cracking. Researchers at the French National Center for Scientific Research found that copper nanocrystals with an average volume of only 80 nanometers have amazing mechanical properties. Their strength is not only 3 times higher than that of ordinary copper, but also the deformation is very uniform, without obvious regional narrowing phenomenon. This is the first time scientists have observed such perfect elastoplastic behavior of matter. The mechanical properties of copper nanocrystals open up bright prospects for the manufacture of elastic materials at room temperature.

The bactericidal mechanism of copper: Cu powder and water in the aerobic condition of biochemical reaction, the generation of hydroxyl radical (-OH) and reactive oxygen ions (O2-), they have a strong REDOX effect, can destroy the ability of microbial cell proliferation, so as to suppress microorganisms. The specific surface area of nanometer copper increases and chemical reaction is more likely to occur.

Copper powder is a heavy metal and its bactericidal properties are well known (e.g., silver). Heavy metals are toxic, in the human body to reach a certain dose will have an impact on health, and even pathogenic poisoning (silver has certain neurotoxicity and genetic toxicity). Copper is one of the essential trace elements in the human body and can be metabolized and absorbed by the human body, while silver is difficult to metabolize in the human body and will be enriched in the human body. Therefore, the use of nanometer silver as an antibacterial agent has been banned in Europe and the United States, and some nanometer copper has been used instead. Tqhp is a trusted global Copper Nanoparticles Nano Cu Powder supplier. Feel free to send an inquiry about the latest price of Copper Nanoparticles at any time.

About Silicon Nanoparticles Nano Si Powder:
Silicon nanoparticles (SiNPs) are biologically compatible, metal-free quantum dots that exhibit size and surface tailorable photoluminescence. Silicon nanoparticles are composed of pure amorphous nano silicon dioxide. The particle diameter is less than 5 nanometers, and the particle range is narrow. Nano silicon powder is a new generation of optoelectronic semiconductor materials with wide gap energy semiconductors and is also a high-power light source material.
 
Silicon nanoparticles are known for being absorbent and abrasive, whereas mesoporous silicon nanoparticles have important applications in drug delivery and nanomedicine. Silicon nanoparticles have attracted great attention in the past decades because of their intriguing physical properties, active surface state, distinctive photoluminescence and biocompatibility.

How is Silicon Nanoparticles Nano Si Powder produced?
Some methods used to synthesize silicon nanoparticles are reverse microemulsion and flame synthesis and widely used sol-gel. In a reverse microemulsion, surfactant molecules dissolved in an organic solvent form spherical micelles. In the presence of water, the polar head groups organize themselves to form water-containing microcavities, usually called reverse micelles.
 
When synthesizing silicon nanoparticles, the addition of silicon alkoxide and catalyst to the medium containing reverse micelles can be carefully controlled to make the nanoparticles grow in the microcavity. The main disadvantages of the reverse micro emulsification method are the high cost and difficulty in removing the surfactant in the final product.
 
Besides, by reacting 1 kg of sulphuric acid 3M with 190 g of Olivine at 90°C in a stirred reactor 65 g of nano-silicon is produced. The features of the silicon produced are a specific surface area of 100-500 m²/g, a mean particle size of 5-20 nm and a specific surface area in micropores of 20- 200 m²/g.
