Pellets, as a clean and renewable energy source, can overcome the shortcomings of high moisture content, expensive transportation costs, non-uniform sizes for agricultural residues. However, traditional pelleting methods are associated with consumption severe mold abrasion due to application temperature pressure. To address these issues while improving pellet solid density durability, urea pret...

Abstract Lanthanum zirconate (LZ) has emerged as a novel thermal barrier coating (TBC) material because of its higher temperature phase stability, and low sintering ability than the current standard yttria-stabilized zirconia (YSZ). In order to combine advantages, LZ YSZ feedstock powders are blended with predetermined weight ratios (50:50) composite coatings. The leading issue in developing us...

During the production of grape wine, the formation of thick leathery pellicle/bacterial cellulose (BC) at the airliquid interface was due to the bacterium, which was isolated and identified as Gluconacetobacter hansenii UAC09. Cultural conditions for bacterial cellulose production from G. hansenii UAC09 were optimized by central composite rotatable experimental design. To economize the BC produ...

Exoglucanase was produced using coffee husk, the by-product of coffee processing industries, as the sole carbon source using economical fermentation strategies like solid-state fermentation (SSF). The effects of process parameters such as pH, moisture and fermentation duration on exoglucanase synthesis was investigated using response surface methodology (RSM) based on three factors and five lev...

The fruit of Melastoma sanguineum Sims is an edible and sweet wild fruit. In our previous study, the fruit was found to have a strong antioxidant property. In this study, an ultrasound-assisted extraction (UAE) method was developed to extract natural antioxidants from the fruit of Melastoma sanguineum Sims, and a response surface methodology was used to optimize the conditions of UAE to maximiz...

In this work, an indirect method for estimating the total amount and concentration of oxidative radicals in aqueous and slurry-phase Fenton's systems was developed. This method, based on the use of benzoic acid as probe compound, was applied for evaluating the effect of the operating conditions on the radicals amount produced, their production efficiency (i.e. moles of radicals generated per mo...

A central composite rotatable design (CCRD) was employed to optimize the beetroot-passion fruit blended juice. The independent variables were beetroot juice (30-70 ml), passion fruit juice (10-30 ml) and sucrose (9.00-10.50g). The combined effect of these independent variables on pH, °Brix and overall acceptability were investigated. Results showed that the generated regression models adequatel...

The development of functional meat products is an innovative trend aiming to meet consumer demand. Microencapsulation a promising alternative ensure probiotic viability, mainly when the wall material resists adverse extrinsic conditions releasing probiotics into intestine. Therefore, Lactobacillus plantarum was encapsulated in Acrycoat S100 by spray drying. encapsulation process analysed using ...

Hexyl butyrate, a green note flavour compound, is widely used in the food industry. The ability of immobilised lipase (Lipozyme IM-77) from Rhizomucor miehei to catalyse the transesterification of hexanol and tributyrin was investigated in this study. Response surface methodology (RSM) and five-level-five-factor central composite rotatable design (CCRD) were employed to evaluate the effects of ...

Magnesium alloys have gained considerable interest as a material for automotive and aerospace applications due to its low density, high specific strength, and good castability. However, another considerable issue is their corrosion properties. This restricts their practical applications. In this present research, corrosion behavior of the AZ31B magnesium alloy was evaluated by conducting salt f...
