Abstract

Purpose

The purpose of this investigation was to study the corrosion protection and structural characteristics of a hybrid organic-inorganic thin film preloaded with green corrosion inhibitor for anticorrosive protection of stainless steel 304L.

Design/methodology/approach

An ethanol solution of the polymerized 3-methacryloxypropyltrimethoxysilan and tetraethylorthosilicate was mixed with henna extract to give homogeneous sols. The morphology, composition and adhesion of hybrid sol-gel coatings were examined by SEM, EDX and pull-off tests, respectively. The surface chemistry of the hybrid sol-gel coatings was investigated with polarization scans and electrochemical impedance spectroscopy (EIS) in the physiological saline solution.

Findings

The polarization curves and EIS data were in agreement. Henna extract additions significantly increased the corrosion protection capability of the sol-gel thin film to greater than 85 percent in the physiological saline solution. In addition, the doped hybrid coating on stainless steel 304L was useful in 3.5 percent NaCl solution.

Originality/value

There have been few reports on the hybrid organic-inorganic thin films preloaded with corrosion inhibitor, as described in the paper, and this environmentally friendly coating on stainless steel 304L was found to be highly effective for industrial applications.

Abstract

Purpose

Food insecurity exists when access to nutritionally sufficient and secure foods or the ability to obtain admissible foods in socially acceptable ways is limited or uncertain. Food insecurity is most likely associated with chronic disease. However, research into the possible relationship between food insecurity and cancer, the world’s second leading cause of death, is limited. The purpose of this study was to determine the level of food insecurity as well as the associated socioeconomic characteristics among cancer patients.

Design/methodology/approach

A cross-sectional study was conducted on 240 cancer patients in Iran. The socioeconomic and 18-item U.S. Department of Agriculture (USDA) Food Security Questionnaires were used to measure general and socioeconomic characteristics, as well as food security status.

Findings

The prevalence of food insecurity was 25.4% in the form of hunger and 52.5% in the form of hidden hunger. Only 22.1% of the patients were food secure. The results of the logistic regression analysis revealed that having children under 18 years old (P = 0.035), economic status (P < 0.001), age of the patient (P = 0.001), educational level of household’s head and his spouse (P = 0.044 and P = 0.045, respectively, had statistically significant relationships with food insecurity.

Originality/value

Cancer patients have a high rate of food insecurity. Considering the importance of food security for effective cancer treatment, the health system’s attention to this issue, particularly by policymakers, appears to be required.
