This study presents the optimal process parameters of zirconium nitride (ZrN) thin films prepared by ion-assisted deposition (IAD) technology combined with electron-beam evaporation based on plasma surface treatment and Taguchi method. We use Minitab statistical software (Version 20.2.0) L9 orthogonal array parameter design response method (RSM). The quadratic polynomial regression equation was...

A recently developed solid-state joining technique called “friction stir spot welding” (FSSW) is used to combine metal alloys with low weldability. Significant experimental work for this study concentrated on the FSSW of AA6063 and AA5083. The involved fixture setup welding pattern parameters sizes material, all which were done a milling machine. cylindrical shoulder concave (10°) square pin pr...

Background: Enzymatic hydrolysis of lactose is one of the most important biotechnological processes in the food industry, which is accomplished by enzyme β-galactosidase (β-gal, β-D-galactoside galactohydrolase, EC 3.2.1.23), trivial called lactase. Orthogonal arrays design is an appropriate option for the optimization of biotechnological processes for the production of microbial...

The symbiotic photovoltaic (PV) electrofarming system introduced in this study is developed for the PV setup an agriculture farming land. discusses effect of different design conditions influenced by annual sunhours on agricultural farm aim to increase panel optimized electricity generation. Therefore, combines Taguchi method with Grey Relational Analysis (GRA) optimize two quality characterist...

Electrospun fibers have high structural similarity to the extracellular matrix. Some researchers tried fabricate cellulose nanofibers using electrospinning, although fabricated usually exhibited a non-uniform texture. Moreover, mats always suffer from low biological and mechanical properties. Thus, objective of this study was first produce naturally occurring banana pseudo-stem. The native then...

Abstract Additive manufacturing (AM) technology has gained significant popularity, among which Fused Deposition Modeling (FDM) emerged as the predominant technique for 3D printing. FDM offers unique ability to achieve desired and tailored engineering properties required specific applications. This experimental study investigates influence of varying process parameters on mechanical highlights o...

Chitinase production by newly isolated Serratia marcescens B4A was optimized following Taguchi’sarray methods. Twenty-three bacterial isolates were screened from shrimp culture ponds in the South ofIran. A chitinase-producing bacterium was isolated based on it’s ability to utilize chitin as the sole carbonsource. The isolate designated as B4A, was identified as Serratia marces...

Adsorption process has been performed to investigate the potentiality of coriander leaf sequester brilliant green (BG) dye from aqueous phase. Coriander 75-micron size characterized by SEM, BET, FTIR etc. In present study, emphasis given on removal BG under different conditions viz. dose biomaterial (10.0 - 100.0 mg), pH (2.0 12.0) and concentration mg/L) Taguchi optimization. The batch experim...

High strength, resistance to corrosion, small density and remarkable strength weight ratio of titanium distinguish it from other metals is a reason for its use in renowned industrial setups like bio-medical, automotive, aeronautics, power generation industries. However, these are considered as difficult-to-machine elements because less heat conductivity, minimum value modulus elasticity, substa...

Metal matrix composite is used in engineering applications due to its superior mechanical properties. MMC’s are reinforced with particle fiber, whisker, and particulate. The size of particulates classified as micro, nano, macro. particulate have excellent form-ability compared fiber whisker composite. has outstanding wear, heat resistance, Many authors been stated the property ability workpiece...
