In this study, five Chlorella species (Chlorella vulgaris, minutissima, pyrenoidosa, sp.1 and sp.2) were grown in various nutrient medium including BG-11, BBM, Fog's M4N for the evolution of biomass lipid production potential. Among tested medium, BG-11 was found most economical efficient all species. To see impact organic carbon sources on potential, microalgae also cultured selected (BG-11) with different like glucose, glycerol, sodium acetate, sucrose under mixotrophic condition. The...
Production of high-octane gasoline is important to improve upon the performance and hence economics oil companies worldwide.
Conventional flame retardants based on polymeric materials demonstrate high flammability, producing huge amounts of smoke, toxic gases and melt drips upon burning, causing immense damage to living beings the environment.
Starch-based biopolymers occupy a significant place in polymer world for replacing plastics derived from petrochemicals. Their non-toxicity, bio-compatible nature and comparable mechanical degradation properties make them suitable candidates various applications, including packaging sector. Starch variety of agricultural waste is converted to bio-composites by chemical modification the presence plasticisers other moieties. These bio-polymers are biodegradable nature; however, they associated...
Polymer nanocomposites offer enhancement in thermomechanical and physicochemical properties of polymers with the presence a little amount nanostructured fillers such as carbon nanotubes, graphene, layered silicates. A facile rapid preparation hytrel (HTL)-graphene oxide (GO) is done via solution mixing method. The influence GO content (0.1, 0.5, 1, 2, 5 wt%) on mechanical thermal GO/HTL has been evaluated by using various techniques tensile testing, thermogravimetric analysis, differential...
Chemical composition of biodiesel plays an important role in deciding its oxidation stability. Bisallylic positions fatty acid ester chain are especially prone to attack by oxygen, leading the formation gums, acids, and polymer deposits that cause failing or plugging problems engine filter as consequences. Although cannot be checked completely, it can slowed using antioxidants, which prevent process from continuing scavenging free radicals, formed oxygen on reactive sites chain. Antioxidants...
In the present study, biomass growth and lipid accumulation of five Chlorella species (Chlorella vulgaris, minutissima, pyrenoidosa, sp.1 sp.2) were compared under different nitrogen concentration sources. addition, all microalgae also grown in a 10 L bubble column photobioreactor outdoor conditions. The results revealed that minutissima have maximum production potential (1.65 g/L) at 35.30 mM concentration. Maximum content was recorded for vulgaris (21.81%) 2.21 Among sources (NaNo3, KNO3,...
The COVID-19 Pandemic have caused severe impact on lives in various ways, but our environment has experienced a positive outcome due to the lockdown which was imposed all over world including Himalayan region of India. worldwide spread COVID 19 reduced movement vehicles, industries and tourism activities. Due shutdown commercial activities traffic helped reclaim naturally. Himalayas is one world's most fragile sensitive hotspots global climate change, with impacts manifesting at particularly...
Vitrimeric materials have emerged as fascinating and sustainable owing to their malleability, reprocessability, recyclability. Sustainable vitrimeric can be prepared by reinforcing polymeric matrix with bioderived fillers. In the current work, a vitrimer is incorporating biomass-derived activated carbon (AC) filler into epoxy achieve enhanced thermal mechanical properties. Thus, biocomposite vitrimers demonstrate lower-temperature self-healing (70°C for 5 min) via disulfide exchanges,...
The adsorption of copper(II) on tea waste has been studied in batch mode using flame atomic absorption spectroscopy for metal estimation. Important process parameters like adsorbent dose, pH, contact time, reaction temperature, shaking speed and particle size were investigated. Adsorption was found to be accordance with Freundlich Langmuir isotherms. maximum amount adsorbed (qm), as evaluated by isotherm, approximately 1.33 mg per gram powder litre solution. optimized observed 3 g adsorbent,...
Sulfated zirconia is a very strong solid acid catalyst which can be utilized for various reactions. The present study focuses on synthesis of zirconia-based with high acidity and surface area, particularly isomerization reaction. has been obtained by sulfation prepared hydrothermal route. was developed impregnating tungstophosphoric sulfated wet incipient method. characterized through Brunauer–Emmett–Teller (BET) temperature-programmed desorption ammonia, temperature program reduction...
