Application

2,2,6,6-Tetramethyl-4-piperidinol has been used to study the green and efficient method for chemoselective deoxidization of graphene oxide via the ultraviolet irradiation.
2,2,6,6-tetramethyl-4-piperidinol has been used to study the irradiation of Camptothecin (CPT) in aerated dimethylsulfoxide (DMSO) solution that leads to formation of singlet oxygen.
Used as:
  • An additive for polymer modified hindered amine light stabilizers
  • A light stabilizer for polyamide 66 fibers containing acid blue dyes

We report a green and efficient method for chemoselective deoxidization of graphene oxide via the ultraviolet irradiation catalyzed with 2,2,6,6-tetramethyl-4-piperidinol. While the sp(2)-hybridized oxygen functional groups are removed after the reduction, the epoxy and hydroxyl groups are retained in the

In the present study, we evaluated the prooxidative mode of action of photoirradiated (+)-catechin at 400 nm in relation to reactive oxygen species generation and its possible application to disinfection. Photoirradiation of (+)-catechin at a concentration of 1 mg/mL yielded not only

Camptothecin (CPT) is an anticancer drug that inhibits topoisomerase I (Topo I) by forming a ternary DNA-CPT-Topo I complex. However, it has also been shown that UVA-irradiated CPT in the absence of Topo I produces significant DNA damage to cancer

A series of Sr-doped BiFeO3 perovskites (Bi1-xSrxFeO3, BSFO) fabricated via sol-gel method was applied as peroxydisulfate (PDS) activator for ciprofloxacin (CIP) degradation. Various technologies were used to characterize the morphology and physicochemical features of prepared BSFO samples and the results

Although arsenic is a well-established human carcinogen, the mechanisms by which it induces cancer remain poorly understood. We previously showed arsenite to be a potent mutagen in human-hamster hybrid (A(L)) cells, and that it induces predominantly multilocus deletions. We show
