USING PRE-OXIDATION TECHNIQUE TO MINIMIZE DISINFECTION BY-PRODUCTS IN SURFACE WATER TREATMENT [PDF]

open access: yesJournal of Environmental Science, 2017
  Reactions between chlorine disinfectants, total organic carbon (TOC), and other chemicals in water form a series of disinfection by-products (DBPs), including trihalomethanes (THMs) that are toxic and suspected carcinogens.

Mathematical modelling of the pre-oxidation of a uranium carbide fuel pellet [PDF]

open access: yesComputers & Chemical Engineering, 2015
Uranium carbide is a candidate fuel for future nuclear reactors. However, for it to be implemented in a closed fuel cycle, an outline for its reprocessing is necessary. One proposed method is to oxidise the uranium carbide into uranium oxide which can then be reprocessed using current infrastructure.

Study of oxygen permeation and molecular structure evolution during pre-oxidation of pitch-based carbon fibers

open access: yes矿业科学学报
Pre-oxidation is attributed to a gas-solid state reaction where oxygen diffuses from the fiber surface to its core along the radial direction. This process is inherently slow, time-consuming, and energy-intensive.
