In January 2024, CIQTEK's benchtop electron paramagnetic resonance spectrometer EPR200M was successfully delivered to Cornell University for research and teaching in the biomedical field.   Cornell University researchers have carried out a number of biomedical research and teaching work based on the EPR200M. The product's simple operation experience, accurate test results, and the prompt service of CIQTEK engineers were well received by the users. They sent a letter of thanks after the delivery of the product: "We find the spectrometer very sensitive and convenient in operation".   Jess Whittemore from Cornell University used a video to show the process of testing solid, liquid samples using the EPR200M.                                                          

We are excited to announce that the new distribution agreement was signed with AXT which will distribute our Diamond Microscope (DM) and Educational Diamond Computer. The following is reprinted from AXT. CIQTEK is the developer and manufacturer of world-leading precision measurement technologies. Established in 2016 they have rapidly grown and currently have over 700 employees of which 70% are in their R&D team and have over 800 customers around the world. They originated from the Key Laboratory of Microscale Magnetic Resonance of the Chinese Academy of Sciences, University of Science and Technology of China and are responsible for over 200 patents, software copyrights and intellectual property assets (pending and granted). CIQTEK’s Diamond Microscope (DM) is a wide-field magnetic resonance instrument based on the principle of spin magnetic resonance in the diamond nitrogen-vacancy centre (NV centre). It offers ultra-high spatial resolution (up to 400nm), high sensitivity (5μT√HZ per pixel) fast imaging and a large field of view (1mm x 1mm). Ideally suited to the characterisation of semiconductors, it also has applications in geology and cell biology. Their Educational Diamond Computer is a teaching instrument based on the diamond’s spin magnetic resonance of the nitrogen-vacancy centre. The desktop design makes it easy to adapt to classrooms, laboratories, and other settings for conducting mechanics and computing experimental courses, while the ability to ability to operate at room temperature (i.e. no cryogenic cooling is necessary) almost negates operating costs. Richard Trett, AXT’s Managing Director commented, “Semiconductors are prioritised national growth areas in Australia. CIQTEK’s products are essential to these areas of research and we hope to remain ahead of the demand for our community, offering them cutting-edge tools so they can continue to push the boundaries of science.” CIQTEK’s Senior Engineer, Dr. Eric Xu replied, “We see the growth potential in Australia and we share AXT’s vision and look forward to working with them to satisfy the needs of Australian researchers”. AXT currently represents over 50 suppliers from around the world. Their portfolio caters for materials science, life science, mining and mineral and non-destructive testing.

Results Brief Appl. Catal. B：Porous graphitized carbon-supported FeOCl as a bifunctional adsorbent-catalyst for the wet peroxide oxidation of chlorinated volatile organic compounds: Effect of mesopores and mechanistic study Wet scrubbing combined with adsorption-enhanced heterogeneous advanced oxidation processes (AOPs) is an effective method to treat chlorinated volatile organic compounds (CVOCs). A porous graphitized carbon (PGC)-loaded FeOCl catalyst was developed by the group of Mr. Jinjun Li from Wuhan University for the effective removal of gaseous dichloroethane, trichloroethylene, dichloromethane, and chlorobenzene. The PGC-loaded FeOCl catalyst was characterized by BET and analyzed for adsorption performance, and it was found that the PGC-loaded FeOCl catalyst had a well-developed mesoporous structure, which could accelerate the diffusion of organic molecules within the particles, and showed better removal performance for CVOCs.

J：Micro-mesoporous graphitized carbon fiber as hydrophobic adsorbent that removes volatile organic compounds from air Activated carbon fibers (ACFs) are a popular class of adsorbents for volatile organic compounds (VOCs). Mr. Jinjun Li's group at Wuhan University prepared hydrophobicity-enhanced porous graphitized carbon fibers (PGCFs) by KOH-catalyzed graphitization and studied their adsorption capacity of representative VOCs, which was characterized to show that PGCFs have a high specific surface area of more than 2,200 m2/g and a micromediaturized pore structure, and that selective adsorption capacity of organics was improved under humid conditions. CIQTEK EASY-V series products used in the study   Chem. Eng. J：Bamboo-derived hydrophobic porous graphitized carbon for adsorption of volatile organic compounds Hydrophobic bamboo-based porous graphitized carbons (BPGCs) were prepared by a composite catalytic graphitization method to study their adsorption performance on toluene, cyclohexane and ethanol, and the specific surface area sizes and micromesopore ratios of the carbon materials prepared at different synthesis temperatures were tested by BET characterization, which provides some theoretical support for evaluating the adsorption performance of carbon materials. CIQTEK EASY-V series products used in the study   Material Adsorption Property Testing Technology Photocatalytic-driven CO2 reduction coupled with photo-oxidative conversion of plastic wastes into value-added chemicals is an effective strategy to address the greenhouse and environmental crises. The porous graphitized carbons (PGCs) and PGC-loaded FeOCl catalysts (FeOCl/PGCs) synthesized at different ratios were characterized by a specific surface and pore size analyzer, and the N2 adsorption and desorption isotherms are shown below in Fig.1d. The adsorption of N2 by PGC0 and FeOCl/PGC0 was mainly in the low relative pressure band at P/P0< 0.1, which is a typical micropo...
