Abstract

In this review segment, use of natural and synthesized 1,4-naphthoquinones for corrosion inhibition was comprehensively covered based on the past research disclosures. The prior arts were gathered from various research article repositories by the use of search terms like ‘Quinonoids as corrosion inhibitors’ and ‘1,4-Napthoquinones as corrosion inhibitors’ as a part of direct referencing. Additionally, back and cross referencing were also done to ensure the complete collection of prior arts. This work will help the researchers to understand the credibility of 1,4-naphthoquinones as corrosion inhibitors in the global platform. Interestingly, the henna leaf extract (aqueous or solvent mediated) having 2-hydroxy 1,4-naphthoquinone (Lawsone, NQ-12) was the most explored phytochemical under natural or green corrosion inhibitor category. More importantly, a few natural extracts having 1,4-naphthoquinones were widely used as corrosion inhibitors in different mediums. With regard to phytochemical extracts, the collective inhibition ability of many phytochemicals will add to corrosion inhibition process. But in recent years, we can observe the use of specific compounds (synthesized/isolated derivatives of 1,4-naphthoquinone) as alone for the intended corrosion inhibition. Under the context of immediate scope, we have disclosed around 23-26 new molecules having 1,4-naphthoquinone framework for experimental ventures towards corrosion inhibition. This work would favor the use of some new 1,4-naphthoquinones in its pure form towards  retarding corrosion with the assistance of  supportive molecular framework.

Abstract

This review initiative had interrelated key aspects like crystal structure, bioavailability, and stereospecific binding capabilities of Atovaquone. Surprisingly, very little literature was available regarding the exploration of different polymorphs of Atovaquone. Interestingly, extensive literature was found towards the bioavailability features and factors specifically related with Atovaquone. Several researchers had attempted to correlate crystal morphology and orientation with the binding properties of Atovaquone and its structurally related compounds. The polymorphic stability of the molecule will play a crucial role in drug formulation and contributes towards the bioavailability of the drug through variations in solubility. Hence for Atovaquone, two factors must be considered: its polymorphic nature and the presence of stereospecific isomers to explain its bioavailability and binding properties. The trans-isomer of Atovaquone, having a specific polymorphic form had provided higher bioavailability, more efficient binding, and an expectedly higher inhibitory activity.

Abstract

The present work was focused on an alternative method for the preparation of clay bricks by the mediation of sodium hydroxide solution as an efficient activator. The traditional brick preparation requires a firing process, but the present innovation avoids it by the use of commercially viable alkali as an activator. Various brick specimens were prepared by the addition of sodium hydroxide solution having different molarities to clay samples. This was done to optimize the process and contribute to process cost reduction. The blends obtained were molded as per the standard brick dimension (19X9X9 cm) and exposed to the ambient atmosphere in a well-ventilated room for curing (14-28 days). The clay samples and the brick specimens were subjected to some critical qualitative tests. Based on the results it was established that increasing the alkali addition to clay had gradually reduced the brick quality. Moreover, the inclusion of fine sand in the blend enhanced the brick quality. In this work, we emphasized optimizing the alkali input, the impact of reduced curing duration, avoiding brick firing, and the fine sand impact on the brick quality.
