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.

On February 26, the 2023 Beijing Annual Conference of Electron Microscopy was successfully held in Beijing, hosted by the Electron Microscopy Professional Committee of the Beijing Physical and Chemical Analysis and Testing Technology Society. CIQTEK was invited to attend this conference to show the latest achievements of SEM, which received an enthusiastic response.   2022 Annual Beijing Electron Microscopy Conference Site   This conference aims to promote the academic and technical level of electron microscopy in Beijing and surrounding provinces and cities at large, to promote the application, development, and communication of electron microscopists in the fields of materials science and life science, etc. Many experts and scholars are invited to make advanced electron microscopy presentations.   In the report, the application expert of CIQTEK shared "the latest progress of Scanning Electron Microscope".   The SEM3300 is a new generation of tungsten filament scanning electron microscope with a resolution better than 2.5 nm and a special electronic circuit design that breaks through the resolution limit of tungsten filament and 5 nm at a low voltage of 1 kV. Excellent image quality, and high-resolution images can be obtained in different fields of view. Large depth of field for stereoscopic images. Extensive scalability to help you explore the world of microscopic imaging.     SEM5000 adopts advanced barrel design, high voltage tunneling technology (SuperTunnel), and low aberration non-leakage magnetic objective design, to achieve low-voltage high-resolution imaging, while magnetic samples can be applied. With optical navigation, perfect automatic functions, well-designed human-machine interaction, and optimized operation and use process, regardless of experience or not, you can quickly get started with high-resolution shooting tasks.   Currently, CIQTEK has launched three tungsten filament SEMs and two field emission SEMs.

In order to optimize environmental pollution and prevention, various cutting-edge technologies and advanced methods urgently need to be popularized and applied.Electron paramagnetic resonance (EPR or ESR) spectroscopy is the only spectroscopic technique that can directly detect and study substances containing unpaired paramagnetic electrons and is widely used in chemical, industrial, life science, material science, and environmental fields, which plays an important role in achieving environmental pollutant management.   At the beginning of 2023, CIQTEK Paramagnetic College will hold a seminar on EPR and environmental pollutant detection from February 22-24, focusing on carbon neutrality and environmental protection. Experts will be invited to share the latest research progress and application results of EPR in water treatment, environmental persistent radical detection, photocatalysis, etc.    CIQTEK sincerely invites experts and scholars in related fields to attend the conference!         CIQTEK EPR (ESR) Spectroscopy    

CIQTEK generously sponsored an annual lectureship and award, given to a young scientist who has made a great contribution to electron paramagnetic resonance (EPR or ESR) research. At the 12th Asia-Pacific EPR/ESR Symposium (APES 2022), the CIQTEK Sponsored Young Scientist Award was awarded to Dr. Fei Kong, CAS Key Laboratory of Microscale Magnetic Resonance and School of Physical Sciences, University of Science and Technology of China.As winner of the 2022 competition, Dr. Fei Kong was invited to gave a prize lecture at the conference, on November 6th.APES 2022, Webinar, November 4-7, 2022CIQTEK is happy to sponsor the APES 2022 during November 4-7, 2022.

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 1980 the Chemical Society and the Royal Institute of Chemistry, together with the Faraday Society and the Society for Analytical Chemistry were amalgamated to become the Royal Society of Chemistry, so that it became a special interest group of the RSC. They are also affiliated to the European Federation of EPR Groups.   The main aim of the RSC ESR Group is to promote innovation, share and advance knowledge, and to encourage applications of electron spin resonance in chemistry, as well as in physical and biological sciences and their applications. These aims are achieved with the aid of an annual international meeting, often followed by publication of proceedings in peer-reviewed international journals.     CIQTEK Booth at RSC ESR Leeds Meeting 2023   CIQTEK will be hosted by our UK distributor SciMed. SciMed will offer UK based sales and service support for the range of EPR spectroscopy and work closely with the CIQTEK team to offer outstanding support to UK users.
