Solution Properties of Substituted o-Cresol Resins

Reproductive toxicology. o-Cresol.

Background: Data from Egyptian studies provide widely varying estimates on the prevalence of premalignant and malignant cervical abnormalities and human papilloma virus (HPVs) infection. To define the prevalence and risk factors of pre-invasive and invasive cervical cancer (cacx), a community based full-scale cross sectional, household survey including 5453 women aged between 35 and 60 years wa...

Spectral properties of substituted coumarins in solution and polymer matrices.

The absorption and fluorescence spectra of substituted coumarins (2-oxo-2H-chromenes) were investigated in solvents and in polymer matrices. The substitutions involved were: (1) by groups with varying electron donating ability such as CH₃, OCH₃ and N(CH₃)₂, mainly, but not exclusively, in positions 7 and (2), by either CHO or 4-PhNHCONHN=CH- in position 3. While the spectra of non-substituted c...

Adhesive properties of Silicone Resins

An experimental study on adhesive properties of Phase I rubber toughened rigid silicone resins was performed to determine the possibility of an application such as structural adhesives. Single-lap shear tests were used to study several parameters, such as the thickness of the joint, the overlap length, the behavior at high temperature and a comparison with different adhesives. Results suggest t...

Photodegradation of o-cresol by ZnO under UV irradiation

The effective removal of o-cresol is currently both an environmental problem. This paper shows how degradation of o-cresol was carried out, in the presence of UV; by ZnO as photocatalyst. To measure the efficiency of photodegradation, the different variables studied included amount of photocatalyst, concentration of o-cresol and pH. The results showed photodegradation was favorable in the pH 6-...
