The purpose of this study is to develop a new protective coating formulation for industrial use, using benzodiazepine derivatives as double function additives.

Benzodiazepine’s derivatives of types (3–5) were prepared and confirmed by infrared, Mass, ¹H-Proton nuclear magnetic resonance (NMR) and ¹³C NMR spectra. The synthesized compound was physically incorporated in the alkyd paint formulation by pebble mill grinding until all particulates are smaller than 20 ums. The prepared coatings were applied by air spray on steel panels. The physical, mechanical characteristics, corrosion resistance and antimicrobial test of the prepared coatings were studied to evaluate the prepared compounds drawbacks.

The results of the mechanical and physical properties of the paint formulation revealed that the paint formulation incorporating benzodiazepines derivatives 3–5 performed best and improved corrosion-resistance and antibacterial activity tests.

In alkyd paint, heterocyclic compounds are the most used antibacterial additives. Other functionalities of these compounds, such as corrosion inhibitors, might be studied to see if they are suited for these applications.

Because of the activity of various benzodiazepine derivatives, which may be attributable to the presence of some function groups such as sulfonamide aromatic amino NH₂ group, and elements such as Sulphur, Nitrogen, Chlorine, in its chemical structure. As a result, paint compositions including these compounds as additives can be used as dual-purpose paint and for a variety of industrial applications.

The research demonstrates how a low-cost paint composition based on synthesized benzodiazepine derivatives 3–5 may be used as a dual-function paint for industrial use.

The purpose of this study was to investigate the inhibitive action of some green leaves on Monel 400 alloy in acidic media.

Green leaves of Mespilus japonica, Ricinus communis L and Vitis vinifera were immersed in methanol solutions, separately, and filtrated after 48 h of immersion; the obtained filtrates were examined as corrosion inhibitors of Monel 400 alloy in hydrochloric acid solution (1.0M HCl). The performance of these inhibitors was evaluated using electrochemical impedance spectroscopy and potentiodynamic polarization. The effect of temperature on corrosion behavior of Monel 400 was also studied.

The results obtained showed that all tested inhibitors performed as good corrosion inhibitors. The inhibition process is attributed to the adsorption of the inhibitors on Monel surface. The adsorption behavior was found to follow Langmiur isotherm. The inhibition efficiencies of extracts increased with increasing the concentration of each inhibitor and deceased with increasing the temperature.

Practical implication These inhibitors could have application in industries where hydrochloric solutions were used to remove the surface impurities of Monel 400.

This paper helps to find new corrosion inhibitors that are safe and eco-friendly.

The most simple equivalent frame system with reduced degrees of freedom is proposed for handling multi‐story multi‐bay infilled frames. The system is composed of homogenized continuum for the reinforced concrete members braced with unilateral diagonal struts for each bay, which are only activated in compression. Identification of the equivalent system characteristics and nonlinear material properties are accomplished from the concepts of inverse analysis approach along with statistical tests of hypotheses is employed to establish the appropriate filtering scheme and the proper accuracy tolerance. The suggested system allows for nonlinear finite element static and dynamic analysis of sophisticated infilled reinforced concrete frames. Sensitivity analysis is undertaken to check the suitability of the proposed system to manipulate various structural applications.

Zakah is an important ethico‐economic institution in the Islamic code of life. It provides a mandatory mechanism for sharing societal resources in a Muslim community. It redistributes income and wealth, plays an important role in poverty alleviation, and thus can contribute to grassroot development. This paper analyzes Zakah's role in this context, and suggests how this institution can be made an instrument of self‐reliance and sustainable development of those who live below poverty line.

This paper aims to investigate the subject matter of Islamic economics that will be the object of a study as a discipline by classifying and unifying different approaches proposed by Islamic economists.

The paper is a conceptual paper using discursive analysis analysing the perspective and approaches proposed by Islamic economists in defining economic problems from an Islamic perspective. The perspective and approaches proposed are classified and analysed for their implications in constructing the subject matter of discipline.

Islamic economics, as a new body of knowledge, needs to clarify the economic problems that will be its subject matter. The paper brings an insight into the subject matter of Islamic economics as conceived by scholars in two approaches, namely, economic problems “as they are” and economic problems “as they should be”. The paper also proposes a unified perspective in defining the subject matter of Islamic economics for further development of the discipline.

This paper only provides philosophical guidance for researchers in mapping the problems and the goals of the policy being studied, although it does not offer any practical use for policymaking as each policy is faced with different and specific cases. This paper may be used to assist future researchers in shaping other unexplored fields in Islamic economics as a body of knowledge.

Islamic economics as a discipline will be strengthened if it has a clear subject matter that will be the object of study. However, the conception of economic problems proposed by Islamic economists is based on life-reality, i.e. of what human beings face in their life (practical-type economic problems as they are) and based on life guidance from the Qur’an on how human beings should live as well as life-objectives, i.e. of what goals he should strive for (ideal-type economic problems as they ought to be) brings implication that there are differences in determining the object of study of Islamic economics.

This paper promotes the unification of two conceptions of economic problems proposed by scholars by defining Islamic economics as “a study of resource appropriation to realize human well-being (maslahah)”. This suggests that economic problems as manifested in life reality will be studied within the grand objective of life in Islam (maqasid al-Shariah), and economic problems as perceived in life goals will be studied in the context of life reality. Islamic economic theory will be formulated not only to solve the apparent problem of “what is” but also formulated in a way that refers to goals (ideals) of “what ought to be” that will provide solutions to current economic problems according to certain vision and to take steps to move in that visionary direction.

Zinc‐ferrite pigment was prepared by solid‐state reaction. A mixture of α‐Fe₂O₃ and ZnO in a molar ratio of 1:1 was fired at 1,200°C. X‐ray diffraction measurements proved that the reacted material crystallized into a spinal structure. Measurement of the pigment specification and properties were carried out according to standard international methods. The pigment extract and the extract of the pigment‐linseed oil mixture were examined for use in protecting steel panels against rust. The prepared pigment was incorporated in some paint formulations. Physical, chemical and mechanical properties of the formulated paint films were studied and also tested for corrosion resistance. Finds that zinc ferrite is a basic pigment and can be recommended for use in anti‐corrosive paints. High corrosion‐resistant coatings can be obtained by incorporating zinc‐ferrite pigment in organic coating systems that cannot saponify; protection increases as the pigment‐binder ratio increases. Chemically follows up and physically emphasizes the mechanism of corrosion protection by the use of a Mossbauer spectroscope.
