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.

Date: 2023.3.27 ~ 2023.3.30 Location: Leeds, England Website: http://www.esr-group.org/conferences/2023-conference-leeds/     The 56th Annual International Meeting of the Electron Spin Resonance Spectroscopy Group of the Royal Society of Chemistry (RSC ESR Group) will be held 27th to 30th March 2023 in Leeds, England.      RSC ESR Group   The ESR Group was founded in 1968 as a forum within the Chemical Society for scientists to share, disseminate and promote knowledge about electron spin resonance. 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.
