H2o2 Oxidation

A new solid substrate-room temperature phosphorimetry (SS-RTP) method for colchicine (COL) detection has been established based on its strong catalytic effect on H2O2 oxidation of acridine yellow (AY), which sharply quenched the room temperature phosphorimetry (RTP) of AY.

Kinetics Of

Hydrogen desorption temperature of MgH2, which was milled with 20 pieces of ZrO2 balls for 20 h, was decreased to 240 °C, although steel−ball−milled MgH2 required more than 350 °C. Moreover, the completely dehydrogenated product was able to absorb hydrogen of ~3.5 mass% even at room temperature under 1 MPa hydrogen within 5 hours. Inductively coupled plasma−atomic emission spectroscopy analysis revealed zirconium element was doped into MgH2 from the ZrO2 balls during the milling process. Therefore, it was concluded that the presence of ZrO2 improved the kinetics of the hydrogenation and dehydrogenation behaviors of MgH2.

The ability of gold nanoparticles (AuNPs) to catalyze reactions involving radicals is poorly studied. However, AuNPs are used in applications where chemical reactions involving transient radicals occur. Herein, we investigate AuNPs’ catalytic effect on 2-propanol oxidation and acetanilide hydroxylation in aqueous solutions under ionizing radiation at room temperature. In both cases, the presence of AuNPs led to selective oxidation of organic radicals, significantly changing the products’ composition and ratio. Based on these observations, we stress how AuNPs’ catalytic activity can affect the correctness of reactive oxygen species concentration determination utilizing organic dyes. We also provide a discussion on the role of AuNPs’ catalytic activity in the radiosensitization effect actively studied for radiotherapy.
