TL;DR: In this paper, a new manganese and dysprosium codoped carbon quantum dots (Mn,Dy-CQDs) with a mean diameter of 1.77 nm was synthesized for fluorescence imaging, T1/T2-weighted magnetic resonance imaging (T 1/T 2 -weighted MRI), and x-ray computed tomography (CT) imaging using a simple one-step hydrothermal approach.

TL;DR: In this article, the technical field of fine chemical coating and a process for producing the same is discussed. And the advantages that the fine chemical coatings prepared by the aid of the process are good in barrier property, and the ageing resistance of the chemical coating can be enhanced; metal can be effectively stopped from being eroded by environmental corrosion media such as water molecules and oxygen.

TL;DR: In this paper, the preparation method of thenitrogen-doped carbon quantum dots comprises the following preparation steps: 1) placing saccharose and ethanolamine in a glass vessel, adding water for three times, fully stirring, and carrying out ultrasonic treatment to obtain a settled solution; 2) placing the settled solution obtained in step 1) in a liner of a polytetrafluoroethylene hydrothermal reactor to obtain reaction liquid; 3) coolingthe reaction liquid obtained in stage 2) to a room temperature, carrying out suction filtration and centrif
