Two polycarboxylate ether copolymers were assessed as superplasticizers (SPs) for hydrated lime pastes modified with two reactive compounds, nanosilica (NS) and ceramic metakaolin (MK). Characterization of the molecular structure of the SPs by Size Exclusion Chromatography, XRD, FTIR and MALDI-TOF (Matrix Assisted Laser Desorption Ionization Time-of-Flight) mass spectrometry was performed. The ...

This study investigates the relationships between flow properties of five blends polyamide 12, with mechanical and physical characteristics fabricated components. The bulk flowability powder were characterised using rheology. Absolute, or skeletal volume 3D printed cubes measured helium pycnometry. tensile behaviour surface hardness specimens from determined. samples correlated used. Comparison...

Isoniazid (INH) is a key antitubercular agent, which exhibits poor chemical stability in the solid state associated with hydrazide group. Cocrystallization Gentisic Acid having antioxidant activity, may produce forms improved pharmaceutical properties. The complementary nature of functional groups isoniazid and chosen coformer resulted success for cocrystal formation. Cocrystal (INH-Gentisic ac...

A good sand mold is an indispensable prerequisite to obtaining a metal casting. Although casting one of the oldest forming technique known humans, it still has lot discover. In bid meet ever-growing demand for quality, economics and increasing environmental restrictions, research ongoing optimize example process making mold. This paper presents comparative study six different foundry sands flow...
