Abstract: A composition for forming a release coating comprises (A) an organopolysiloxane having an average of at least two carbinol functional groups per molecule. The composition also comprises (B) a polyisocyanate component. Component (B) comprises (b1) an isocyanate-functional copolymer and (b2) a polyisocyanate different from component (b). The release coating formed with the composition is not a foam. A release coating formed with the composition is also disclosed. In addition, a method of preparing a coated substrate comprising a release coating disposed on a substrate, as well as the coated substrate formed in accordance with the method, are disclosed.

Abstract: The present disclosure relates to the technical field of electrical device state monitoring, and particularly discloses an open-phase fault monitoring system, in which a relay communication unit is configured with an MCU as a central control processing unit, and an external ADC realizes high-speed A/D conversion for a plurality of signals; a timing function is realized by a GNSS&RTC of the relay communication unit, a data interaction function is realized by a LORA module, and data is sent to a background industrial personal computer based on a designed sampling frequency. The system of the present disclosure has the advantages of small volume, high precision, low cost, easy installation and the like, and realizes real-time monitoring and accurate identification of a line open-phase fault of an auxiliary power supply system in a nuclear power plant.

Abstract: A composition for forming a release coating comprises (A) an organopolysiloxane having an average of at least two carbinol functional groups per molecule. The organopolysiloxane (A) is present in the composition in an amount of from 50 to 99 wt. % based on the total weight of the composition. The composition further comprises (B) a polyisocyanate. The release coating formed with the composition is not a foam. A release coating formed with the composition is also disclosed. In addition, a method of preparing a coated substrate comprising a release coating disposed on a substrate, as well as the coated substrate formed in accordance with the method, are disclosed.

Abstract: Provided are a preparation method and use of a high-entropy alloy (HEA)@carbon fiber composite nanomaterial. Five or more metal salts of different metal elements are dissolved in an organic solvent, a complexing agent is added to obtain a mixture, and then the mixture is stirred to obtain a mixed metal salt solution. A polymer is added to the mixed metal salt solution, and dissolved by stirring to obtain an electrospinning precursor solution. The electrospinning precursor solution is transferred into a syringe and the syringe and a syringe needle is kept free of air bubbles, and electrospinning is then conducted to obtain a precursor fiber membrane. The precursor fiber membrane is subjected to vacuum drying, a resulting dried sample is subjected to pre-sintering, and a resulting pre-sintered sample is then subjected to calcination to obtain the HEA@carbon fiber composite nanomaterial.
