In the present study, implant material Ti-6Al-4V has been coated with eudragit (EU) and chitosan (CH) polymers to enhance surface properties. The deposition of polymer coating has covered the surface cracks to a significant level and the fact has been confirmed by FE-SEM coupled with EDAX wherein the atomic percentage of Ti (99.90%) in non-coated surface has been decreased markedly to 0.42% after coating. Scratch resistance and adhesion power of bilayer coating has been increased as indicated by the higher critical loads Lc 1 (16.71 N), Lc 2 (17.56 N), Lc 3 (17.96 N) when a progressive load of 1 N to 20 N is applied over the coated surface. Further, Electrochemical impedance spectroscopy (EIS) and potentiodynamic-polarization studies have shown that the value of polarization resistance is inversely proportional to the corrosion rate. Thus decrease in the corrosion rate from 107.5×10 -2 (mm year -1 ) for the non-coated alloy to 2.88×10 -2 (mm year -1 ) for CH/EU coating demonstrated that coating enhanced the corrosion resistance of the alloy in the physiological condition. The in vitro antibacterial test conducted against S. aureus, B. subtilis, P. vulgaris and P. auregenosa has shown a significant inhibition zone of 9 mm, 6 mm, 7 mm and 10 mm, respectively, thus indicating the possible application of the polymeric coating material on the dental implants.

The garlic and ginger peels have been thrown as a waste. Nowadays researchers have been trying to investigate the antimicrobial properties of garlic and ginger peels extracts. Nevertheless, the effects of these materials on synthetic leather have not been experimented. The study aims at antimicrobial treatment of synthetic leather by the peels extracts and examining it against the staphylococcus epidermis bacterium. The peels have been collected in Bahir Dar city, Ethiopia, dried in the oven for one hour at 104°C, weighed and grounded in a grinder with a mesh size of 50-300 mesh. For both materials, 40 g of peel powder has been dissolved in 400 mL of ethanol solvent and stirred by a magnetic stirrer and then extracted by ultrasonic extraction method. Leather samples have been treated by extracted peels (5%, 15% and 20%) together with citric acid as a binder and soap as wetting agent. The antimicrobial properties of the treated samples have been assessed by a disc diffusion test method. The garlic peel extract at all concentrations levels has a wider inhibition zone indicating that garlic peel extract is more efficient at inhibiting Staphylococcus epidermis growth than ginger peel. Therefore; it could be used as antimicrobial treatment of synthetic leather.

The current work communicates the entropy generation analysis of oscillating flow of magnetohydrodynamic couple stress nanofluid in a vertical channel. The main objective of present study is to examine the entropy analysis of a magnetohydrodynamic couple stress nanofluid. In this study, water and ethylene glycol (50:50) and diamond are used as the base fluid and nanoparticles, respectively. The effects of radiative heat, Ohmic, and viscous dissipation are all considered. By employing the perturbation process, the governing partial differential equations are transformed into the set of ordinary differential equations, which are then deciphered by implementing the Runge-Kutta fourth-order scheme with shooting technique. The obtained outcomes reveal that, amplifying viscous dissipation promising the temperature whereas the reverse is true for the influence of couple stress viscosity and Hartmann number. Heat transfer rate is decelerating with the boost up in Hartmann number at the walls while it is accelerating with the increment in viscous dissipation at the right wall. Entropy is escalating for intensifying viscous dissipation, and thermal radiation whereas the reverse is true for the impression of couple stress viscosity, and volume fraction of nanoparticles. Bejan number is falling for escalating volume fraction of nanoparticles, and viscous dissipation while it is enhancing with escalation in couple stress parameter.

Degradation of phenol by heat-activated, ZVI-activated, AC-activated, heat/AC-activated, and heat/ZVI-activated persulfate have been investigated. As a result, the degradation of phenol fitted well with pseudo-first order kinetic model. For the solution with phenol concentration of 100 mg/L, degradation efficiency of nearly 100% and reaction rate constant of 0.0506 min -1 are realized by heat-activated persulfate when reaction temperature is 70℃, concentration of persulfate is 15 g/L, reaction time is 120 min under neutral pH. Besides, the highest degradation efficiency and reaction rate constant of phenol by ZVI-activated are respectively, 92.85% and 0.0198 min -1 when concentration of ZVI is 5 g/L, concentration of persulfate was 15 g/L, and reaction time is 120 min under neutral pH. Furthermore, the highest degradation efficiency and reaction rate constant of phenol by AC-activated persulfate are 99.1% and 0.0373 min -1 , respectively with persulfate concentration of 5 g/L and AC concentration of 5 g/L under neutral pH in 120 min. Moreover, the heat/AC-activated and heat/ZVI-activated persulfate are showing obvious synergistic effect during degradation process of phenol, and the reaction rate constants of heat/AC-activated and heat/ZVI-activated persulfate are respectively, 0.0512 and 0.0561 min -1 . The radical scavenger experiments proved that both SO 4-• and OH• are significant radicals in degradation of phenol by ZVI-activated and AC-activated persulfate, and SO 4-• are predominant radicals in degradation of phenol.

In this article a magnetic carbon (MEHLC) has been synthesised from Euphorbia hirta leaf (EHL) extract to investigate the adsorption capacity of lead(II) ions from aqueous solutions and industrial wastewater. The prepared magnetic carbon (MEHLC) is compared with raw material (EHL) under the batch adsorption process such as contact time, pH, adsorbent dose and temperature. The adsorbents are characterized by FT-IR, SEM and EDX studies. The maximum removal is obtained at 300 K and the Langmuir isotherm of MEHLC and EHL is found to be with applicable qm value of 385.86 and 21.96 mg g-1, respectively. Various thermodynamic parameters, including the standard Gibbs free energy (∆Go), standard enthalpy (∆Ho) and standard entropy (∆So), are evaluated. The MEHLC and EHL are tested with lead(II) plating wastewater through a batch mode process over five cycles; MEHLC showed better results than EHL.

Manganese oxide (MO) has been synthesised by chemical co-precipitation method and it was characterised for its functional group, phase structure, particle size and morphology by using FTIR, XRD, SEM and TEM. Additionally, its electrochemical properties like cyclic voltammetry (CV), galvanostatic charge/ discharge and electrochemical impedance spectroscopy (EIS) are recorded. The specific capacitance of the prepared manganese oxide is found to be 116 F/g at current density of 1 A/g. To augment its capacitance value, it was doped with multi-walled carbon nanotube (MWCNT) and poly(3,4 ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) and their electrochemical performance are recorded. By doping MWCNT and PEDOT:PSS over MO, a high specific capacitance of 537 F/g at a current density of 1 A/g with 97% capacitance retention and coulombic efficiency of 98% over 10,000 cycles at a current density of 5 A/g is obtained. All these results demonstrates that MO/MWCNT/PEDOT:PSS is a promising electrode material for supercapacitor application.

ZnO-TiO2 nanocomposites (ZTN) have been synthesized using both ultrasound-assisted and conventional methods. The characterization techniques like XRD, FTIR, BET, FESEM, EDS, and UV-visible confirmed that the ZTN is successfully formed. The photocatalytic activity and kinetics of the ZTN are assessed using methylene blue (MB) dye as a pollutant. Various factors such as synthesis processes, catalyst loading, initial dye concentration, temperature, and pH have been investigated to determine their impact on dye degradation. The ZTN synthesized with ultrasound exhibited superior photocatalytic activity compared to the conventionally synthesized ZTN. The highest dye degradation (97.69%) was observed under the optimum conditions of 1 g/L photocatalyst dosage, 20 ppm dye concentration, pH 10, and a temperature of 55℃. Additionally, the kinetic study revealed that the degradation of the dye by ZTN followed a second-order kinetic model.
