Laxminarayan Institute of Technology (abbreviated LIT or LIT Nagpur) (Marathi: लक्ष्मीनारायण तांत्रिक संस्था) is a government institute of higher education in the field of Chemical Engineering in Nagpur, India. It was established in 1942 and is one of the oldest engineering colleges for Chemical Engineering and Technology in India.
This paper reported NIR heat reflective performance of the epoxy based paint that formulate using RE (RE = Dy, Mn, Ce, Dy/Fe) doped ZnAl2O4 white / color pigment which has been synthesized by two different techniques such as combustion method and solid –state method. Further phase purity and crystallite size pigments has been confirmed by XRD techniques. From SEM analysis microcrystalline surface morphology of the pigment has been clearly observed. From the Diffuse reflectance spectra NIR heat reflective performance of the prepared epoxy based paint using RE doped ZnAl2O4 white or colour pigment, has been successfully monitored by coating it on glass surface which exhibits good NIR reflectance. From, the different RE doped host, ZnAl2O4:Dy pigment shows high NIR reflectance as compared to other, which was used in paint formulation. Hence, prepared RE doped ZnAl2O4 pigment may find promising scope as a whitish or color pigment for cool coating application.
Meat alternatives focus on creating environmentally friendly products that mimic regular meat’s physical characteristics and nutritional properties. Occasionally, the safety and quality of meat products can be compromised by several admitted and non-admitted methods. It could undergo procedures to increase weight (adding non-nutritional foreign proteins) or prolong the product’s shelf life (adding food additives). This study aimed to develop and optimize a vegan patty with a rich fibrous structure, nutritional qualities, and sensory attributes that resemble meat. This study employed the response surface methodology (RSM) to optimize the vegan patty of regular meat. Based on RSM trials, we varied the proportion of five significant ingredients: jackfruit (34–38
In the present work, evaluation of two catalysts, activated carbon (AC) synthesized from agricultural waste and multiwalled carbon nanotubes (MWCNT) synthesized from plastic waste, was done for the ozonation of real textile wastewater using para-chloro benzoic acid (p-CBA) as a probe compound. The effect of pH and catalyst dose were studied in terms of •OH exposure, Rct, rate of p-CBA degradation and ozone degradation. The rate constant for the reaction of organic matter with hydroxyl radicals was determined using competition kinetics. The threshold ozone dose for real textile wastewater was found to be 0.51 gm/gm of TOC. With an increase in specific ozone dose, the rate of p-CBA degradation was found to be increasing and has shown a positive effect on •OH exposure and Rct. The increasing pH had shown a positive effect on the rate of degradation and decomposition of p-CBA and ozone, respectively, in the case of AC-catalyzed ozonation. A similar trend was observed in the case of MWCNTs catalyzed ozonation. A positive effect of pH was observed on •OH exposure and Rct, in AC as well as MWCNTs catalyzed ozonation. The effect of catalyst loading has shown significant enhancement in p-CBA degradation, ozone decomposition, •OH exposure and Rct in both AC as well as MWCNTs catalyzed ozonation. However, MWCNTs have proved better than AC as a catalyst for ozonation in studied experimental parameters.
