Industrial Control System Security: The Lifeline of Smart Manufacturing When the Ukrainian power grid suffered widespread outages due to a hacker attack, and when the control system of the Guri Dam in Venezuela was compromised, the security of Industrial Control Systems (ICS) has become the lifeblood of national critical infrastructure. This article will reveal the … Read more
Abstract Recently, Professor David W. C. MacMillan, a 2021 Nobel Prize winner in Chemistry from Princeton University, reported a novel photonic/nickel cooperative catalysis strategy based on the double decarboxylative cross-coupling (SH2) reaction, which can be used to construct valuable C(sp3)-C(sp3) coupling products from aliphatic carboxylic acids. Detailed mechanistic studies indicate that this reaction involves an … Read more
Continuing from the previous article, this section will further introduce the types of radicals.The research team from Ohio State UniversityNagibsummarized the polarities of oxygen-centered radicals and sulfur-centered radicals.Oxygen-centered radicals are shown in Table 8. Unlike carbon-centered radicals substituted with oxygen (e.g., α– or β– alcohols), where the influence is determined by polarizability rather than electronegativity, … Read more
