In Korea, for heavy metal-contaminated soil, there are insufficient basic data as well field application cases soil washing. This study was conducted to suggest the significant factors and optimal operation conditions maximum metal removal efficiency. Five types of washing solution [acid (HCl), citric acid, oxalic EDTA, CaCl2], time (10–360 min), solid-solution ratio (1:2–1:100) were selected o...

Friction Stir Welding (FSW) is a solid-state joining process for metals, non-metals and polymers. It carried out with the help of specially designed, non-consumable tool. The heat required, creating softened region at faying surfaces, generated by rotation tool against work piece material. Being welding process, it offers several advantages like inducing minimum effect on mechanical properties ...

Kojic acid is widely used to inhibit the browning effect of tyrosinase in cosmetic and food industries. In this work, synthesis of kojic monooleate ester (KMO) was carried out using lipase-catalysed esterification of kojic acid and oleic acid in a solvent-free system. Response Surface Methodology (RSM) based on central composite rotatable design (CCRD) was used to optimise the main important re...

Chickpea is considered among the most important leguminous crops in world but not a regular meal pulse due to their long cooking time and lengthy preparatory procedure. This gives rise need of converting raw chickpea into convenient food. For preparation instant from Desi Kabuli variety, Central Composite Rotatable Design (CCRD) under Response Surface Methodology (RSM) was employed which consis...

Enzymatic degumming (EDG) is an emerging alternative process for decreasing the phosphorus content, increasing oil yield, and preserving quality. Purifine® 3G a cocktail of phospholipases composed phospholipase A2 (PLA2), C (PLC), phosphatidylinositol (PI-PLC). In this study, was applied to crude soybean oil, optimum conditions (enzyme concentration, temperature, water dosage) were determined u...

About 70% of the harvested coffee is exported to industrialized nations for value addition due lack processing and logistic facilities in developing producer countries, thus leaving behind a marginal economic return growers. This research was conducted investigate roasting capacity an innovatively developed batch-type directly solar radiated system decentralized using energy. Central composite ...

Abstract A new approach was used for the immobilization of Thermomyces lanuginosus lipase (TLL), Candida antarctica B (CALB), and Rhizomucor miehei (RML) on amine-functionalized magnetic nanoparticles (Fe 3 O 4 @SiO 2 -NH ) via a multi-component reaction route (using cyclohexyl isocyanide). The method offered single-step very fast process covalent attachment lipases under extremely mild conditi...

Non-catalytic hydrogenation of liquid natural rubber (LNR) via thermal decomposition 2,4,6-trimethylbenzenesulfonylhydrazide (MSH) is reported in this study. Parameter studies the reaction were performed by utilizing combination response surface methodology and central composite rotatable design (RSM/CCRD). The effects each variable interaction between two variables (i.e. MSH:LNR weight ratio t...

The aim of our study was to select the optimal operating conditions to permeabilize Kluyveromyces lactis cells using ethanol as a solvent as an alternative to cell disruption and extraction. Cell permeabilization was carried out by a non-mechanical method consisting of chemical treatment with ethanol, and the results were expressed as β-galactosidase activity. Experiments were conducted under d...
