The spectrally selective solar absorption paint is prepared from spinel-based mixed metal oxides with inorganic binder as a key component. Inorganic binder (furnace cement) is blended with mixed metal oxide pigment during synthesis. High temperature stability upto 1,100ºC is achieved by the use of this modified coating system. The purpose of this paper is to work on solar selective coating synthesis, and application of a coating as a water-borne paint is the additive key feature that helps in reduction of solvent use.

The paint was formulated using water-based system, and the main component of colorant was made by mixed metal oxide–based spinel pigment and highly temperature stable inorganic binder.

The paint formed shows excellent absorptive power with low emittance even at high temperature. Optical and thermal properties were determined along with adhesion, abrasion and other properties. The solar absorptance for these samples were as = 0.93–0.95 with corresponding thermal emittance of eT = 0.096 (at room temperature) and 0.2–0.22 (at elevated temperature 100°C).

The paint formed shows excellent absorptive power with low emittance even at high temperature. The paint can be applied in solar absorptive tower system. The obtained results indicated excellent thermal stability of prepared paint coatings. As inorganic binder was used, the paint has reduction in solvent use, and being water as a base, it is environment friendly, easy to apply and durable at high temperatures, as the binder itself is stable up to 1,500ºC.

The purpose of this paper is to develop a context dependent, multi perspective multilevel trust measurement instrument to measure supply chain members' trust.

Since trust is a context dependent phenomenon and the level of trust between partners cannot be measured easily, a conceptual framework is developed to measure supply chain partners' trust from risk perspective (i.e. risk related to characteristics, rational and institutions/security) considering the relationship as “Risky”, “Risk‐worthy” and “Not risky” and translated them in terms of trust perspectives as “No trust”, “Trust worthy” and “Trust”.

Although the research on trust emphasizes to focus on a member's characteristics such as benevolence, integrity, ability, reliability, credibility, etc, decision to trust require multiple judgments therefore trust should be measured from various context dependent perspectives at multiple levels in relationship from trustor's perceptions and calculations. The key perspectives of trust in supply chain relationship are; characteristics trust, rational trust (cost and benefit, dynamic capabilities, technology) and institutional trust/security system. An important argument of this concept is that trust can only be dyadic.

Researchers on trust have repeatedly confirmed that trust is a multifaceted and context dependent concept. However the business context may not remain the same in the dynamic business environment, therefore this conceptual framework can be used as generalized trust measurement tool.

This paper has attempted to develop a simple and practical multi level trust measurement tool for the complex multi‐dimensional construct of supply chain partners' relationship trust.

This study may be one of the first to develop a multi level trust measurement concept from risk perspectives.
