'Science' Publications: CIQTEK EPR Facilitates Research on Catalytic Reactionisms

Recently, the research teams led by Professor Aiwen Lei from Wuhan University and Professor Lin He from Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, made a significant breakthrough in asymmetric urea synthesis. Their research results, titled "Synchronous recognition of amines in oxidative carbonylation toward unsymmetrical ureas" were published in the prestigious international journal "Science" on November 15th. Published in "Science" with the Support of CIQTEK EPR Unsymmetrical ureas are important compounds widely used in medicine, agriculture, and materials science. The synthesis of unsymmetrical ureas through amine reactions is the most effective method. However, achieving high selectivity in synthesizing unsymmetrical ureas is challenging due to the competitive reactivity of the two amines. So far, no metal-catalyzed method can efficiently and selectively recognize and install multiple amines at the same site. In their research, the teams deeply analyzed the electron transfer process between copper salts and amines and successfully detected the in situ-generated ammonium radical cation and its captured radical species with DMPO during the reaction. This provided crucial evidence for revealing the copper ion-mediated free radical activation mechanism of secondary amines. Combining the selective nucleophilic activation of primary amines by cobalt catalysts, the teams designed a "synchronous recognition strategy" that achieved efficient carbonylation reactions of a 1:1 molar ratio of two amines, producing highly selective unsymmetrical urea products. This achievement provides new avenues for the industrial production of unsymmetrical urea compounds and is expected to have broad applications in fields such as medicine and agriculture. It also demonstrates the precise characterization capabilities of the EPR spectrometer developed by CIQTEK, providing strong support for researchers to deepen their understanding of reaction mechanisms and develop innovative synthesis strategies. The research paper was published in "Science" and can be accessed at the following link: https://www.science.org/doi/10.1126/science.adl0149 A "Timely Rain" that Achieves Customer Satisfaction, Scripting a Success Story Behind this achievement is a story of collaboration between CIQTEK and the research team. In October 2021, an imported EPR spectrometer at the College of Chemistry and Molecular Sciences, Wuhan University, encountered a sudden malfunction. After contacting the manufacturer, they learned that the repair would take a long time. This posed a challenge for the experimental work of the faculty and students. In December of the same year, at the invitation of the faculty, engineers from CIQTEK overcame the challenges posed by the pandemic and arrived on-site to troubleshoot the issue. They quickly identified a problem with the magnet po...

Cornell University Researchers Use CIQTEK ESR Spectrometer to Analyze the Spectrum of Free Radicals in Samples

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. "
