On November 24, 2022, CIQTEK successfully held the new electron microscope launch event "Make the Invisible, Visible". Based on the diversified needs of users, CIQTEK launched SEM3300, which "Redefines Tungsten Filament SEM"; SEM2000, which is "Easy But Not Simple"; SEM4000, which is "Super High Beam Current, Super Fast Analysis".     >> SEM3300 In the new product launch session, CIQTEK Vice President Feng Cao introduced three new electron microscopes in detail. The first to be unveiled was the SEM3300, a tungsten filament scanning electron microscope, which is a perfect blend of technology and industrial design. With a resolution of 2.5 nm at 20 kV, a 16% improvement over ordinary tungsten filament electron microscopy, a resolution of 4 nm at 3 kV, a 2-fold improvement, and a resolution of 5 nm at 1 kV, a 3-fold improvement, the SEM3300 has significantly surpassed ordinary tungsten filament electron microscopy in all voltage bands, redefining the industry standard for tungsten filament scanning electron microscopy.Take the diaphragm material in lithium batteries as an example, the details of the conventional tungsten filament electron microscopy are blurred and unclear (Figure a below), while the diaphragm pictures taken by SEM3300, the diaphragm pores are clearly visible and the edges of the pores are sharp (Figure b below).   Figure a: Li-ion battery septum photographed by conventional tungsten filament electron microscopy, with blurred details.   Figure b: SEM3300 photographed lithium battery diaphragm, diaphragm pores clearly visible, sharp edge of the hole.     >> SEM2000 Tungsten filament SEM2000 is a product that is not fussy in its operation. It is built with the goal that everyone is able to use it, with a simple interface and rich expandability. If you want a simpler tool, SEM2000 will be your best choice.   >> SEM4000 The Field Emission Scanning Electron Microscope SEM4000 is a new product for analytical users' needs. It features a high electron beam current and fast analysis speed, with a maximum electron beam current of over 200 nA and continuously adjustable beam size, which facilitates the selection of the most suitable imaging and energy spectrum conditions.   Make achievements for customers, make achievements for peers Dr. Yu He, CEO of CIQTEK, expressed his gratitude to all the guests for their care and support of CIQTEK in his speech. Dr. Yu He said, CIQTEK engraved innovation in its genes, put customers in its heart, insisted on pragmatic innovation with "no compromise", and developed the new product SEM3300 which redefines the industry standard of tungsten filament electron microscope, allowing the tool to return to the tool itself so that users can better rest assured in scientific research.

The Excellent Oral Presentation Awards are presented during the closing ceremony of the 12th Asia-Pacific EPR Symposium (APES2022) on November 7th, 2022. CIQTEK is pleased to sponsor this award to scientists who have contributed significantly to electron paramagnetic resonance (EPR or ESR) research. This time, congratulations to Dr. Shen Zhou from the National University of Defense Technology, Dr. Sergey Veber from the International Tomography Center of SB RAS, and Dr. Zhiyuan Zhao from the University of Science and Technology of China for winning the awards.APES 2022, Webinar, November 4-7, 2022CIQTEK is happy to sponsor the APES 2022 during November 4-7, 2022. The symposium this year is an online event for international speakers and participants, a new start for Asia-Pacific EPR/ESR Society in the post-epidemic era. The main aims of APES 2022 are to bring together EPR/ESR spectroscopists and to promote and facilitate collaboration among the EPR/ESR community. APES 2022 is intended to stimulate discussions on the forefront of research in all aspects of EPR/ESR ranging from theoretical and experimental advances in CW/Pulsed EPR, high frequency, and high field EPR, ENDOR, PEDLOR/DEER, time-resolved EPR, FMR, MRI, ODMR to applications in medicine, biology, chemistry, materials science and nanotechnology. On November 6, Dr. Sergey Veber gave a presentation entitled "X-band EPR spectrometer based on MW bridge with 300 W solid-state amplifier and AWG unit". Abstract of the PresentationTechnical advances in modern EPR spectrometers set up the frontiers of EPR-related methodologies and approaches. Considering EPR spectrometers of conventional microwave bands, such as X- and Q-, high-power amplifiers, arbitrary wave generators, and fast digitizers are the essential units required for up-to-date pulse EPR techniques.Herein we describe an X-band EPR spectrometer constructed in the Magnetic Resonance Laboratory of Biomolecular Systems (NIOCH SB RAS) and featuring all the required equipment to perform state-of-art pulse EPR experiments. Among the general construction of the spectrometer, the scheme of the microwave bridge is considered in detail including a pulse-forming and pulse-monitoring unit, and a low-noise amplifier with a pulse protection circuit. A modular open-source software "Atomize" (https://github.com/Anatoly1010/Atomize) is used to control the spectrometer including AWG and fast digitizer cards featuring high-speed data streaming. A wideband dielectric EPR resonator was developed to fit the requirements for AWG experiments with chirp pulses. The spectrometer is designed to have a high dynamic range, low coherent noise and to capture the direct dimension efficiently. These capabilities were demonstrated with both rectangular and AWG pulse experiments.

Methods 15, 697–699 (2018)]. A key figure of single-molecule EPR is that it can resolve heterogeneous molecular information, which is averaged in conventional EPR measurement. However, the current single-molecule measurements are insufficient to do so, due to the poor spectral resolution. Here, I will introduce an easy way to substantially improve the spectral resolution, i.e., removing the magnetic field. The zero-field EPR has been well-studied for decades [Chem. Rev. 83, 49–82 (1983)]. It has narrower spectra with the tradeoff of much poorer sensitivity. Difference from conventional inductive detection, the signal of NV-EPR comes from the statistical fluctuation rather than the thermal polarization of spins, which does not depend on the magnetic field. Therefore, the NV center is an ideal sensor for zero-field EPR detection. I will show that the NV-EPR has the advantage in not only spatial resolution but also spectral resolution.Biography of Dr. Fei KongDr. Fei Kong was born in Hefei, China. In 2012 he obtained a B.Sc. degree at the University of Science and Technology of China (USTC) and later undertook experimental research there on control and simulation using nitrogen-vacancy centers in diamond with Prof. Dr. Jiangfeng Du and Prof. Dr. Fazhan Shi. He received a Ph.D. degree based on this work in 2018. After 3 years of postdoctoral research on t...
