    Take "Meow Star Man" as an example! Application of scanning electron microscope in the study of animal hair microstructure

    "Everyone has hair~" Hair is a derivative of the cuticle of mammalian skin epidermis and one of the characteristics of mammals. All animal hairs have their basic shape and structure, and different animals show differences in hair morphology (such as length, thickness, color, etc.). The difference of hair morphology must be closely related to its microstructure. Therefore, the microstructure of hair has also been the focus of research for many years [1]. In 1837, Brewster first used an optical microscope to discover the specific structure of hair surface, marking the beginning of hair microstructure research. In the 1980s, with the wide application of electron microscope in the study of hair microstructure, the study of hair microstructure has been improved

    Automatic specific surface area tester: an accurate instrument for exploring the micro world

    In the research of modern materials science, specific surface area is a crucial parameter. It directly affects the adsorption, catalysis, reaction and other properties of materials. In order to measure and evaluate the specific surface area of materials more accurately, the automatic specific surface area tester came into being and became an accurate instrument in the hands of scientific researchers. The automatic specific surface area tester adopts advanced measurement principles and technologies to measure the specific surface area of materials through physical adsorption or gas adsorption. Its working principle is based on the adsorption equilibrium theory, that is, when gas molecules contact with the solid surface, an adsorption layer will be formed on the solid surface. By measuring the amount of gas in the adsorption layer, the specific surface area of the material can be calculated. Compared with the traditional specific surface area testing method, the automatic specific surface area tester has

    What is the difference between paper and paper? Scanning electron microscope will show you the truth

    Paper not only records the changes of civilization, but also still plays an important role in today's human society. In terms of use, paper can be divided into packaging paper, printing paper, industrial paper, cultural paper, household paper and special paper. In addition to the appearance that can be recognized by the naked eye, what are the differences between them at the micro level? Today, we will take you to explore with the help of the scanning electron microscope of Guoyi Quantum. Paper is made from raw materials containing plant fibers through pulping, modulation, copying, processing and other processes. Scanning electron microscope is an effective tool for microstructure analysis. Its advantages include direct observation of sample surface structure, multi angle observation of samples, large depth of field, stereoscopic image, wide image magnification, high resolution, and little pollution and damage to samples

    The "high-speed hunter" in the micro world: exploring the mystery of high-speed scanning electron microscope

    In the vast universe of science, there is a precision instrument called high-speed scanning electron microscope. Like a high-speed hunter, it gallops in the micro world, capturing those wonderful scenes that are hard to detect with the naked eye. High speed scanning electron microscope (HSEM) is a bright pearl in the field of modern materials science research. It uses high-speed electron beam as a detection tool to scan the sample surface point by point, and forms a high-resolution image by collecting the information generated by the interaction between electrons and samples. The emergence of this technology has greatly promoted the research process in materials science, biology, chemistry and other fields. Compared with traditional optical microscope, HSEM has higher resolution and larger magnification. It can not only clearly show the nanometer level
