SAT NANO is specialized in manufacturing top-quality Zinc Ferrite Nanopowder, and their production process is innovative. This revolutionary method, known as "pulsed laser ablation" is a green and environment-friendly technique that converts Zinc Ferrite Target into powder form using a high-energy laser. Compared to the traditional methods such as hydrothermal, co-precipitation, and microwave-assisted methods, the pulsed laser ablation method is faster, greener as it doesn't produce waste and the produced nanomaterial is pure with fewer defects.

With the development of integrated circuit (IC) technology, the scaling of silicon-based metal oxide semiconductor (MOS) field-effect transistors (FETs) is approaching their fundamental physical limits. Carbon nanotubes (CNTs) are considered promising materials in the post silicon era due to their atomic thickness and unique electrical properties, with the potential to improve transistor performance while reducing power consumption. High purity aligned carbon nanotubes (A-CNT) are an ideal choice for driving advanced ICs due to their high current density. However, when the channel length (Lch) decreases below 30nm, the performance of single gate (SG) A-CNT FET significantly decreases, mainly manifested as deteriorating switching characteristics and increased leakage current. This article aims to reveal the mechanism of performance degradation in A-CNT FET through theoretical and experimental research, and propose solutions.

As an important physical property of powders, specific surface area refers to the total surface area per unit mass of oxide powder. And its size is influenced by various factors. Firstly, particle size is an important factor affecting the specific surface area of powders. The smaller the particles, the larger the specific surface area. This is because the smaller the particle size, the larger the surface area of each individual particle, thereby increasing the total surface area per unit mass of powder.

Researchers have made a breakthrough in the development of carbon nanotube (CNT) reinforced aluminum composites by utilizing ultra-short CNTs with unique intra-crystalline dispersibility. The nanoscale carbon nanotubes are uniformly distributed within the ultra-fine aluminum grains. When compared with typical CNT/Al composites with inter-granular CNT dispersion, this intra-crystalline carbon nanotube/aluminum composite has a stronger ability to anchor and maintain dislocations, resulting in enhanced strength and ductility. This innovative intra-crystalline dispersal strategy provides a new avenue for developing strong and tough nanocarbon reinforced metal-based composite materials. The research has been published recently in a prestigious academic journal.

There are different methods to measure the particle size of powders, depending on the size range of the particles and the desired accuracy of the measurement. Here are some common techniques:

There is a certain relationship between the conductivity and thermal conductivity of materials. Conductivity is the ability of a material to conduct current, while thermal conductivity is the ability of a material to conduct heat. Both of these properties are related to the electron and heat conduction inside the material.
