“…Right now, several techniques are utilized for the treatment of wastewater effluents. Among these incorporates precipitation with coagulation and flocculation, ion-exchange, membrane separation (Eltayeb & Khan, 2019;Khan et al, 2019;Kilic et al, 2014aKilic et al, , 2014b; complexation of dry biomass, filtration and adsorption (Çalımlı et al, 2019;Demirbaş et al, 2019aDemirbaş et al, , 2019b. Be that as it may, a portion of these strategies, for example, precipitation and ion-exchange have critical disadvantages which are related with their significant expenses, less effectiveness, requiring a lot of reagent and dissolvable and age of harmful muck.…”

The heavy metals are exceptionally responsive at low fixations and can accumulate in the food web, causing extreme general wellbeing concerns. Remediation utilizing customary physical and substance techniques is uneconomical and creates huge volumes of compound waste. Bioremediation of risky metals has gotten impressive and developing enthusiasm throughout the years. Adsorption of Cr 3+ and Fe 2+ from its aqueous solution on biosorbent Mango leaf powder (MLP) was prepared from matured Mango (Mangifera indica) leaves. The study was carried out by batch adsorption experiments using atomic adsorption spectroscopy upon various parameters used to assess their impact on the adsorption of metal ions. The achieved results evidenced the adsorption of Cr 3+ and Fe 2+ on MLP is better. The higher adsorption ability was shown about 237.5 and 227.5 mg/g respectively at 50 mg/L concentration of metal ions and 100 mg/L of MLP. Besides, the adsorption of Cr 3+ and Fe 2+ on MLP was found to be fitted with the Freundlich isotherm. Thermodynamic results showed the sorption process is feasible, spontaneous, and endothermic. Kinetic parameters had shown that the adsorption of Cr 3+ and Fe 2+ ions found as pseudo-second-order kinetics; also this current study proposing that ABOUT THE AUTHORS Dr. Ramesh Duraisamy, Industrial Chemist's working as an Associate Professor in Arba Minch University, Ethiopia.

“…It is expected, since the nanotubes length as a material parameter determines the levels of aspect ratio and interfacial area. In addition, a high "l" parameter increased the level of excluded volume, which decreased the percolation threshold of nanoparticles in the nanocomposites (see Equations (6) and (7)). Furthermore, the "s" parameter shows the stress transfer as a function of interfacial interaction/adhesion at the interface.…”

“…The carbon nanotubes (CNT) as ideal nanoparticles can add high stiffness and good electrical conductivity to polymer matrices. Additionally, the nanoscale diameter and large aspect ratio of CNT significantly improve the general properties of polymer CNT nanocomposites (PCNT) [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. The van der Waals attraction between nanotubes leads the aggregation/agglomeration in the nanocomposites, which reduces the filler surface expanse and interrupts the networking level [18][19][20].…”

The establishment of interphase region around nanoparticles accelerates the percolating of carbon nanotubes (CNT) in polymer nanocomposites reinforced with CNT (PCNT), due to the linking productivity of interphase district before the physical connecting of nanoparticles. Therefore, the interphase is an important character in the networks of CNT in PCNT. Here, a simulation study is presented to investigate the interphase connection in the mechanical possessions of PCNT including tensile modulus and strength. A number of models comprising Takayanagi, Ouali, Pukanszky and Callister are developed by the assumption of an interphase district in the CNT excluded volume. The advanced models depict the optimistic influences of reedy and lengthy CNT besides dense interphase on the stiffness and tensile power of nanocomposites. The Pukanszky calculations depict that the interphase strength plays a more noteworthy role in the nanocomposites strength compared to the CNT length.
