Typically, the cooling fan is connected to the system through a three-wire interface, which includes a power cable, a ground cable, and a Tach cable (speed signal cable). In order to be able to read Tach signals through GPIO, you need to select a fan that supports this feature. Such fans are often referred to as "ach-enabled" (supporting Tach) or "RPM-sensing" (supporting speed detection) fans. The Tach signal is a pulse signal whose frequency is proportional to the speed of the fan. Typically, a pulse signal is generated for each rotational speed cycle. Here are some steps to help you implement a cooling fan that reads Tach signals via GPIO: 1, Make sure that the fan you choose supports Tach function or speed detection function. You can find this information in the fan specifications and instructions.       2. Connect the Tach wire of the fan to the available GPIO pin. This usually requires the use of cables or connectors.       3, Use the appropriate hardware interface circuit to convert the fan's Tach signal into a digital signal that can be read. This is because GPIO typically operates at the digital signal level.       At Chungfo Electronic Technology Co., LTD., we not only provide high quality waterproof exhaust fans, but also various sizes small exhaust fan price are affordable . It can't be ignored that our brushless exhaust fans not only have excellent performance, but also energy saving and environmental protection.

Scanning Electron Microscopy (SEM) is based on the principle of using a focused beam of high-energy electrons to probe the surface of a sample and produce a high-resolution detailed image.   Electron Source: SEM works by using an electron source, typically a heated tungsten filament or a field emission gun, to produce a beam of electrons.   Electron Beam Generation: The electron source emits electrons, which are accelerated to high energies by an electric field. The electrons are focused into a narrow beam using electromagnetic lenses.   Sample Interaction: The primary electron beam is directed onto the sample's surface. When the beam interacts with the sample, several types of interactions occur, including scattering, absorption, and emission of secondary electrons.   Scattering: The primary electrons may undergo elastic or inelastic scattering while interacting with the atoms in the sample. Elastic scattering results in a change in direction of the electron beam, while inelastic scattering leads to energy loss due to interactions with the sample's atoms.   Secondary Electron Emission: Some of the primary electrons knock off secondary electrons from the surface of the sample through inelastic scattering. These secondary electrons carry information about the sample's topography and composition.   Signal Detection: The emitted secondary electrons, along with other signals such as backscattered electrons and characteristic X-ray emissions, are detected using various detectors. Some common detectors in SEM are the Everhart-Thornley detector for secondary electrons and detectors for backscattered electrons or X-rays generated by the sample.   Image Formation: The detected signals are then amplified and processed to form an image. The signal intensity is typically converted into a grayscale or false-color representation, allowing the visualization of surface features and details.   Scanning: To generate a complete image, the electron beam is systematically scanned across the surface of the sample in a raster pattern. The intensity of the detected signals at each point is recorded, allowing the construction of a high-resolution image.   Image Display and Analysis: The final reconstructed image is displayed on a monitor or recorded for further analysis. SEM images can be used to examine the microstructure, morphology, elemental composition, and surface characteristics of a wide range of materials.   In short, scanning electron microscopy utilizes the interaction of a focused, high-energy electron beam with a sample to generate detailed images. By analyzing the signals emitted by the sample, SEM provides valuable information about the surface topography, morphology, and composition of the sample at high resolution. It is widely used in a variety of scientific and industrial applications for research, quality control, and materials characterization.   CIQTEK offers various high-quality SEM equipment for researchers and industrial users.

The g-value plays a crucial role in EPR (Electron Paramagnetic Resonance) spectroscopy in understanding the electronic structure and magnetic properties of paramagnetic substances. Today, we will talk about the key factor in EPR spectroscopy: the g-value (g-factor).   The g-value is a dimensionless quantity that represents a constant of proportionality between the magnetic field and the energy difference between the energy levels in the system. The g-value can be obtained by measuring the resonance frequency of a paramagnetic substance absorbing electromagnetic radiation in the presence of a magnetic field. It represents the extent to which the electron spin interacts with the external magnetic field. The g value is commonly used to determine important characteristics of paramagnetic substances, such as the number of unpaired electrons and their orbital angular momentum.   For a free electron, the g value is a constant of 2.0023, derived from fundamental physical properties. However, in more complex systems, such as transition metal complexes or organic radicals, the g value can deviate from this standard value. The deviation arises due to various factors, including spin-orbit coupling and hyperfine interactions with nearby nuclei. These interactions introduce additional energy levels and modify the electron's behavior in the magnetic field, leading to different g values.   By analyzing the g value in EPR spectroscopy, scientists can gain insights into the molecular structure and chemical environment of the paramagnetic species under investigation. A change in the g value can reveal the presence of different ligands or coordination environments around a metal ion, providing valuable information about the electronic configuration and coordination chemistry. In addition, the g-value can be used to study the dynamics of a system. For example, it can provide information about the rate of electron transfer or spin relaxation processes, revealing the kinetics and mechanisms involved in chemical reactions or biological processes.   A common method of measuring the g-value is using EPR spectroscopy on a sample with a known g-value. This reference sample can be a compound with a well-characterized g-value or a spin probe, such as a stable organic radical. By comparing the position and shape of the resonance signals of the reference sample and the sample of interest, the g-value of the unknown species can be calculated.   Another approach involves calculating the g value from the Zeeman effect. The Zeeman effect describes the splitting of energy levels in a magnetic field. By measuring the magnetic field strength required to observe resonance at different frequencies, the g value can be derived using the equation g = hν/μBΔB, where h is Planck's constant, ν is the microwave frequency, μB is the Bohr magneton, and ΔB is the magnetic field difference between the resonance peaks.   In addition, the g value can be determined by analyzing the linewidth of the EPR signal. Since the g value depends on the orientation of the unpaired electrons in the magnetic field, any interaction or fluctuation in the environment will broaden the EPR signal. The g-value can be estimated by measuring the linewidth and analyzing its dependence on the magnetic field strength.   It is worth noting that the g value is not always a fixed constant. In some cases, it may vary due to factors such as electron-electron interactions or electrons leaving the domain. These variations can indicate the chemical or physical properties of the paramagnetic substance. In summary, the g-value in EPR spectroscopy is an important parameter that helps characterize paramagnetic substances. By determining the g-value, researchers can gain valuable insights into the electronic structure and properties of paramagnetic compounds, contributing to understanding a wide range of scientific disciplines, including chemistry, physics, and biology.   Click here to read more application notes on EPR spectroscopy.

Electron paramagnetic resonance (EPR), also known as electron spin resonance (ESR), is a technique used to study the magnetic properties of materials containing unpaired electrons.   Here is a brief explanation of how electron paramagnetic resonance works:   Unpaired electrons: Many materials, such as transition metal ions or organic radicals, possess unpaired electrons. These unpaired electrons have intrinsic magnetic properties.   External magnetic field: A strong, static magnetic field is applied to the sample being studied. This field aligns the magnetic moments of the unpaired electrons in the sample.   Resonance condition: A microwave source emits electromagnetic radiation with a specific frequency, typically in the microwave range. The frequency is adjusted until it matches the resonance condition, where the energy of the microwave radiation corresponds to the energy difference between electron spin states.   Absorption of energy: When the resonance condition is met, the unpaired electrons can absorb energy from the microwave radiation and transition from one spin state to another. This absorption of energy is detected as a decrease in the intensity of the microwave radiation passing through the sample.   EPR spectrum: By varying the magnetic field strength, the absorption of energy is recorded as a function of the magnetic field. The resulting EPR spectrum shows distinct absorption peaks or lines, providing information about the magnetic properties of the sample, such as the number of unpaired electrons, their spin orientation, and their interaction with the surrounding environment.   Overall, EPR measures the response of unpaired electrons to external static magnetic fields and microwave radiation, allowing scientists to study the electronic structure and magnetic properties of materials. Therefore, EPR technology has a prominent role in many fields such as chemistry, biology, medicine, food and beverage, etc. CIQTEK's self-developed EPR spectrometer supports researchers in many application areas. Click to view the EPR application notes.

In the field of analytical instrumentation, both Electron Spin Resonance (ESR) spectrometers and Nuclear Magnetic Resonance (NMR) spectrometers play an important role. Although they use similar principles, there are significant differences between the two techniques.   ESR Spectrometer: Electron Spin Resonance (ESR) spectrometers are employed to study the behavior of unpaired electrons within a sample. Unpaired electrons possess a magnetic moment and can be analyzed using microwave radiation. ESR spectrometers use a strong magnetic field to split the energy levels of these electrons and measure the energy absorption or emission during electron spin transitions. CIQTEK EPR Spectrometers   NMR Spectrometer: On the other hand, Nuclear Magnetic Resonance (NMR) spectrometers focus on the study of the nuclear spins of atoms within a sample. Nuclei possessing an odd number of protons or neutrons have a non-zero nuclear spin and behave like tiny magnets. NMR spectrometers employ a strong magnetic field and radiofrequency pulses to excite and detect the nuclear spins, generating a signal that can be analyzed. NMR Image Frrom Internet   Key Differences between ESR and NMR:   Target: ESR spectrometers focus on unpaired electrons, while NMR spectrometers examine the nuclear spins of atoms.   Technique: ESR utilizes microwaves, while NMR employs radiofrequency pulses.   Sample Types: ESR can analyze paramagnetic materials and free radicals, while NMR is widely used for organic compounds, proteins, and other molecules.   Applications:  ESR - The investigation of free radicals in biological systems. It helps scientists understand the role of free radicals in various diseases and the effects of antioxidants on their stability.  - The study of paramagnetic materials, which have unpaired electrons and exhibit unique magnetic properties.   NMR - In chemistry, particularly in determining the structure of organic compounds, researchers use NMR to decipher the connectivity of atoms within a molecule, providing vital information about its composition and spatial arrangement.  - In biological research, such as studying protein structure and dynamics.   Price: ESR spectrometers are generally less expensive than NMR spectrometers, making them more accessible to smaller research labs and educational institutions. NMR spectrometers are sophisticated instruments and typically more costly due to their complex design, higher magnetic field strengths, and advanced capabilities.   Conclusion: ESR and NMR spectrometers differ in their target entities, techniques, and applications. ESR explores unpaired electrons, while NMR focuses on nuclear spins. Both instruments contribute significantly to scientific advancements, enabling researchers to unravel the mysteries of matter at the atomic and molecular levels.
