Some beginners of electron paramagnetic resonance (EPR) spectroscopy often face problems such as unclear basic principles, difficulty analyzing spectra, and unskilled operation of instruments. To help our users better utilize EPR spectroscopy, CIQTEK launched this "EPR Mini-course" series to answer the problems encountered by users in their EPR studies and experiments. Please feel free to email us at info@ciqtek.com for your specific questions.   Q1: An accessory used to determine orientation-dependent samples (e.g., single crystals) is a (   ). A. Goniometer B. Field/frequency lock system C. Gaussmeter D. Xenon lamp ------ Answer: A   Q2: The following options are important applications of high-frequency (e.g., W-band) EPR technology ( )? A. Direct detection of living organisms  B. To improve the sensitivity of detection of small numbers of samples [the same number as in low-frequency (e.g., X-band) detection].   C. To improve spectral resolution ------ Answer: BC   Q3: True or False: For EPR testing, microwave power should be reduced before changing samples.  ------ Answer: True. For EPR testing, make sure to reduce the microwave power to less than 40 dB. It is not permitted to remove the sample from the resonant cavity under high microwave power or to move the sample drastically, otherwise, serious detuning of the microwave bridge circuit may be caused, and the detector diode may even be burned out.   Q4: The viscosity of a solvent affects the rate of movement of the molecules, which in turn affects their EPR spectra. The figure below shows the EPR spectra of TEMPOL in water or glycerol system, the correct match is ( ).  A. ①water system; ②glycerol system  B. ①glycerol system; ②water system ------ Answer: A. Glycerol is more viscous than water, and in the glycerol system, the motion of the TEMPOL molecules slows down and exhibits an anisotropic spectral signature.   This session is over. See you next time!

Recently, the world's first commercial low-temperature Scanning Nitrogen-vacancy Probe Microscope (SNVM) was released in Hefei, Anhui, China. This instrument is mainly used to detect the surface magnetism of nanomaterials and will provide a new method for research in fields such as materials science, condensed matter physics, and life sciences. The instrument was independently developed by CIQTEK, marking a new breakthrough in the industrialization development of precision measurement technology.   Precision measurement refers to the use of properties such as energy level transitions, coherent superposition, and entanglement to achieve substantial improvements in measurement accuracy, sensitivity, resolution, etc.   The CIQTEK Scanning Nitrogen-vacancy Probe Microscope (SNVM) is an advanced scientific analytical instrument that combines diamond nitrogen-vacancy (NV) optical detected magnetic resonance (ODMR) technology and atomic force microscope (AFM) scanning imaging technology, which can realize quantitative and non-destructive magnetic imaging of magnetic samples with high spatial resolution and high sensitivity.   In addition to diamond NV color centers, there are many technical routes for precision measurement, including atomic magnetometers, atomic clocks, etc. Atomic magnetometer is a technology that uses the interaction between light and atoms to detect magnetic fields, which can detect coronary heart disease and abnormal heart rate. As a new generation of atomic clock, optical lattice clock can currently achieve an error of only 1 second in tens of billions of years. Each technical route shows its unique capabilities according to the application scenarios.     SNVM for Magnetic Imaging of BFO Films Precision sensors are known as "a key to the microscopic world." It is not only small, but also very sensitive. It can detect many signals that were undetectable and inaccurate in the past, such as brain magnetism and cardiac magnetism. It can be used for early diagnosis of neurological diseases, coronary heart disease and other diseases. At the same time, precision measurement has also brought about some innovations in detection methods, such as leakage current detection in lithium batteries in the new energy field, power grid management in the energy exploration field, and chip current imaging in the semiconductor/integrated circuit field.     SNVM for Imaging A Single Vortex Stray Magnetic Field The industry regards precision measurement as another "ripe industrialization" direction in the field of information technology, and technological innovation is becoming increasingly active. In recent years, many start-up companies in the field of measurement have been hatched around the world to explore various application scenarios and promote the progress of commercialization.     SNVM for Twisted Bilayer CrI3 Measurements Precision measurement is to change "invisible" to "visible"...

Continuing with the previous research and article, Cornell University researcher - Jess Whittemore, used a demonstration to show the process of capturing and quantifying free radicals emitted from cigarettes to investigate the harmful effects of free radicals which in addition to tars may lead to cancer.   To analyze the spectra of free radicals in samples, she used the benchtop ESR spectrometer developed by CIQTEK.   As she described "The CIQTEK benchtop spectrometer is rather compact which is a great advantage for using in all kinds of laboratory. But beyond that it has remarkable sensitivity for our ESR studies. For this reasons we believe that this benchtop ESR spectrometer by CIQTEK is the best on the market. "
