The waste management sector is moving towards sustainable approaches for facilitating resource-recovery possibilities. Agriculture residue (rice straw), cow dung (cattle waste), and clam shells from the ocean are the primary waste materials possessing a huge value addition opportunity. In this study, the effective usage of rice straw and anaerobic sludge from cow dung for bio-energy production was studied.

- Aluminum casting was performed with various Ti concentrations (0.1, 0.2, and 0.3%) in addition to Mg and Mn, using a graphite crucible, and the microstructure was modified via hot rolling to about 2 mm thick.!
- Mechanical testing showed that the Ultimate Tensile Strength improved significantly with increasing Ti content, reaching up to 345 MPa with 0.3 wt% Ti under water quenching, marking a 32.6% increase compared to 0 wt% Ti.!
- Corrosion tests revealed that while heat-treated alloys exhibited good resistance to corrosion in a salt solution, higher Ti content led to increased corrosion rates, attributed to enhanced grain refinement.
Article Synopsis
- The study focused on optimizing two types of hardeners, polyaminoamine adduct (Aradur 450 BD) and polyamidoamine adduct (Aradur 3282 BD), for use with DGEBA epoxy resin to create coatings for mild steel panels.
- Six coating samples (E-0, E-1, E-2 from Aradur 450 and F-0, F-1, F-2 from Aradur 3282) were produced and characterized using various analysis techniques, including FE-SEM and FTIR.
- Results showed that the coatings had similar thermal and mechanical properties, but E-1 and F-1 coatings exhibited superior corrosion resistance, especially under exposure to 3.
In the present study, the stress corrosion cracking (SCC) behavior of ECAP Al5083 alloy was investigated in air as well as in 3.5 % NaCl solution using the slow strain rate tensile test (SSRT). The characteristics of grain boundary precipitates (GBPs), specifically the microchemistry of the SCC behavior of Al5083 alloys, both in "as-received" condition and when deformed by the ECAP process, were examined.

Casting of pure aluminum with different concentration and combinations of alloying additives such as cupper (Cu), magnesium (Mg) and silver (Ag) were carried out using a graphite crucible. The as-cast microstructure was modified by hot rolling followed by different heat-treated conditions viz.
