The impact of salinity on the physiological and biochemical parameters tolerant (‘Bonica’) susceptible (‘Black Beauty’) eggplant varieties (Solanum melongena L.) was determined. results revealed that increase in contributes to a significant decline net photosynthesis (An) both varieties; however, at highest salt concentration (160 mM NaCl), decrease photorespiration (Rl) less pronounced cultivar ‘Bonica’. Stomatal conductance (gs) significantly reduced ‘Black Beauty’ following exposure 40...
Porous materials constitute an attractive research field due to their high specific surfaces; chemical stabilities; abundant pores; special electrical, optical, thermal, and mechanical properties; often higher reactivities. These are currently generating a great deal of enthusiasm, they have been used in large diverse applications, such as those relating sensors biosensors, catalysis biocatalysis, separation purification techniques, acoustic electrical insulation, transport gas or charged...
In this study, we evaluated the use of prickly pear seed cake, a by-product oil extraction, as new precursor for producing activated carbon by phosphoric acid activation, and obtained carbon’s capacity heavy metal removal from aqueous solution. Response surface methodology based on full factorial design at two levels (24) was developed to reduce number experiments reach optimal preparation conditions cadmium lead ions solutions. Design Expert 11.1.2.0 Trial software used generating...
To investigate the impact of biochar on eggplant growth, physiology, and yield parameters under separate associated drought salt stress, a pot experiment was carried out. An variety ('Bonica F1') exposed to one NaCl concentration (S1 = 300 mM), three irrigation regimes (FI: full irrigation; DI: deficit ARD: alternate root-zone drying irrigation), dose (B1 6% by weight). Our findings demonstrated that stress had greater negative 'Bonica F1' performance in comparison single or stress. Whereas,...
The impact of heat and drought stresses, either individually or combined, on physiological biochemical parameters four eggplant varieties (Solanum melongena L.) was investigated. results showed that associated stress generated the highest increment in proline content, MDA concentration, H2O2 accumulation lowest RWC. In addition, ‘Bonica’ ‘Galine’ exhibited higher starch lower electrolyte leakage (EL) under combined stress. Moreover, stresses applied contributed to a substantial decline Chla,...
The aqueous extract from the bark of Punica granatum L. was invested to generate CuO nanoparticles CuSO4 using a green, economical, ecological, and clean method. synthesized were characterized successfully used as adsorbents for methyl green retention an absorptive capacity amounting 28.7 mg g−1. Methyl equilibrium adsorption data correlated Langmuir model following pseudo-second order kinetics model. This study clearly corroborates that copper exhibit high potential use in wastewater treatment.
This study emphasized the efficiency of unconventional delignification treatment "Acetocell" as a basic pretreatment to isolate cellulose fiber from Tamarix aphylla's stem. Chemical proprieties obtained were determined and its for cadmium ions adsorption was evaluated subsequently. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction analysis, thermogravimetric analysis (TGA), Scanning Electron Microscopy (SEM), fluorescence microscope Morfi used analyze thermochemical...
The large sizes of cations and anions organic salts are the driving force for application ionic liquids (organic salts) in harsh salty conditions. Moreover, formation crosslinked liquid networks as anti-rust anticorrosion protective films on substrate surfaces repels seawater salt water vapor from their surface to prevent corrosion. In this respect, an imidazolium epoxy resin polyamine hardener were prepared by condensation either pentaethylenehexamine or ethanolamine with glyoxal...
The oxidation of chlorobenzene (CB) was studied by electrochemical electrolysis using boron-doped diamond (BDD), PbO2 or platine (Pt) as anode and graphite bar cathode. effect applied current density, supporting electrolyte initial pH value were also studied. results demonstrated that BDD had the best effectiveness accomplishment degradation CB compared to Pt anodes. For a density 20 mA/cm2 at = 3, elimination COD TOC about 97% 98%, respectively, after 360 min with anode. Pseudo-first order...
Abstract New trinuclear mixed‐valent Co III ‐Co II complexes with salen‐type ligands have been synthesized and characterized both in the solid state solution. These complexescomprise a central CoCl 2 unit connecting two [RCo(4,4′,7,7′tmsalen)] fragments chlorides acting as bridging between metals, while ion completes its octahedral coordination through salen oxygen donors. Complex 1 (R = CH Cl), which has cis Cl at ion, approximate C symmetry, whereas centrosymmetric complex CF 3 ) contains...
