Study of Gelatin-AM-DMC Graft Copolymerization under Microwave Radiation and its Strengthening Effect to Wood Pulp
Gelatin Graft Copolymerisation Microwave Radiation Paper Dry-Strengthening Agent
2011/12/20
Graft copolymerization of acrylamide (AM) and methyl acrylacyl oxyethyl trimethyl ammonium chloride (DMC) onto gelatin under microwave radiation was studied. The resultant ternary graft copolymer was ...

Thermal annealing of radiation damaged titanite
Thermal annealing radiation damaged titanite
2012/4/1
Radiogenic impurities of 400 to 800 ppm U and Th in titanite, CaTiSiO5, lead to mod-erate radiation damage (?.5 3 10 18 a-decay events/g) and therefore to partial amorphi-zation (?0%). Powder X-ray di...

Nature and Stability of Radiation-Induced Defects in Natural Kaolinites: New Results and a Reappraisal of Published Works
EPR Kaolinite Radiation induced defects RID
2011/12/29
A new appraisal of radiation-induced defects (RID) in natural kaolinite, i.e., positive trapped holes on oxygen atoms, has been undertaken using Q-band EPR spectra, recorded at 93 K, of irradiated ann...
Adsorption and Desorption of N-Methyl 8-Hydroxy Quinoline Methyl Sulfate on Smectite and the Potential Use of the Clay-Organic Product as an Ultraviolet Radiation Collector
