Study the Corrosive Effect of Greenhouse Gases on Metallic and Non-metallic Materials

By Rajesh Kumar Singh, Rajeev Kumar, Vikas Kumar

Abstract: Carbon dioxide is a major corrosive pollutant for building materials. It enters inside materials by diffusion or osmosis process and in presence of moisture it produces H2CO3 which decrease the pH value and accelerates chemical and electrochemical reaction with building materials. The carbonation reaction produces deterioration inside and outside of building materials. It produces corrosion reaction with metallic bar and disbanding with concrete. CO2 reacts with Ca (OH)2 and Mg(OH)2 …

Turn-On” Fluorescence Sensing of Bilirubin Using Water-Soluble Conjugated Polymer

By T. Senthil Kumar, Vedant Joshi, Sachin ., Nishtha Arora, Aruna Kukreti

Abstract: Early detection of bilirubin is important to detect jaundice and hepatitis disease at the early stage. Currently, there is no fast method available to detect bilirubin level directly in the presence of crucial interference. This report presents a novel water-soluble poly(fluorenes-alt-benzothiadiazole) for turnon sensing of bilirubin in water and human blood serum. The probe is the water-soluble conjugated polymer poly(fluorenes-alt-benzothiadiazole) functionalized with a D-glucuronic acid named PF-BTGlcA. D-glucuronic acid acts …

Preparation and Evaluation of Plant-Based Coir Fiber-Reinforced Polypropylene Composites

By Haydar Zaman, Ruhul A. Khan

Abstract: In the present article, unidirectional coir fiber (CF) and alkali-treated CF (ACF) were incorporated in polypropylene (PP) with and without 3-aminopropyl trimethoxy silane (AS) and tetramethoxy orthosilicate (TS) to produce composites by a compression molding technique. The basic properties of PP/CF composites (e.g. tensile strength, tensile modulus, impact strength, and water absorption) have enhanced with increasing CF content. The incorporation of AS and TS after alkali pretreatment for CF composites …
