Equilibrium, Kinetic and Thermodynamic Studies for the Adsorption of Metanil Yellow Using Carbonized Pistachio Shell-Magnetic Nanoparticles

Water (2022)

Adnan Adnan Muhammad Ovais Omer Behramand Khan Inkisar Khan Muhammad Alamzeb

The cost-effective adsorbents of carbonized pistachio shell magnetic nanoparticles (CPSMNPs) were synthesized. SEM, EDX, and BET characterized the prepared CPSMNPs. The CPSMNPs were used as adsorbents to remove Metanil Yellow (MY) dye. The adsorption of MY was investigated with the effect of pH, contact time, initial dye concentration, adsorbent dose, and temperature. The SEM image of CPSMNPs reveals fine particles with an average size of 400–700 nm and a substantial surface area increase (112.58 m2/g). The EDX analysis confirms the carbonization of PS to CPS and the successful impregnation of Fe3O4 nanoparticles. CPSMNPs showed excellent adsorption efficiency, i.e., 94% for adsorption of MY of 10 mL of 100 ppm MY at optimum conditions. Kinetics data fit pseudo-second-order kinetics. The Langmuir isotherm better represents the equilibrium data with the spontaneous sorption process. This study investigates that the synthesized nanoparticles have an excellent texture and can be used as a special adsorbent for the adsorption of wastewater pollutants like MY.

Visualization of thermal characteristics around the absorber tube of a standard parabolic trough thermal collector by 3D simulation

Majedul Islam Azharul Karim Suvash C. Saha Prasad Yarlagadda S.A. Miller

Three dimensional conjugate heat transfer simulation of a standard parabolic trough thermal collector receiver is performed numerically in order to visualize and analyze the surface thermal characteristics. The computational model is developed in Ansys Fluent environment based on some simplified assumptions. Three test conditions are selected from the existing literature to verify the numerical model directly, and reasonably good agreement between the model and the test results confirms the reliability of the simulation. Solar radiation flux profile around the tube is also approximated from the literature. An in house macro is written to read the input solar flux as a heat flux wall boundary condition for the tube wall. The numerical results show that there is an abrupt variation in the resultant heat flux along the circumference of the receiver. Consequently, the temperature varies throughout the tube surface. The lower half of the horizontal receiver enjoys the maximum solar flux, and therefore, experiences the maximum temperature rise compared to the upper part with almost leveled temperature. Reasonable attributions and suggestions are made on this particular type of conjugate thermal system. The knowledge that gained so far from this study will be used to further the analysis and to design an efficient concentrator photovoltaic collector in near future.

Abstract Palladium(0)‐catalyzed Suzuki cross‐coupling reactions of the bis(triflates) of 2′,4‐dihydroxybenzophenones afforded 2′,4‐diarylbenzophenones. The reactions proceeded with very good site selectivity in favour of the 4‐position.

Towards the development of stable and efficient novel waste ceramics composites

Heliyon (2021)

Mohammad Sohail Sanaullah Khan Mohammad Saleem Khan Ihsan Ullah Muhammad Omer

Natural resources are non-renewable and facing a regular depletion due to their immense use which demands new and additional material's reserves, recycling technologies and materials with no or less bad environmental effects. Reuse of waste materials will be rewarding technically, economically and environmentally. Here, we report the incorporation of industrial ceramic wastes in polymer matrix as composite materials to investigate their potentials for various applications. Ceramic wastes were collected from the premises of ceramic producing industries located at Peshawar (Pakistan). The composites of ceramic particles and polyaniline (PANI) were produced via in-situ free polymerization technique. SEM and FT-IR analysis confirmed composite formation. Thermal, dielectric and mechanical properties of the prepared materials were studied. It was found that both the constituent materials (ceramic and polymer) have a synergistic effect on each other. At one hand, ceramic wastes support and enhance the thermal and mechanical properties of the polymer in composites and the polymer in turn beautify the wastes with good dielectric and electrical properties. Based on their properties, the low cost and environmentally friendly novel composites could be used for various applications such as semi-conductors, capacitors and microwave devices.

One-Pot Synthesis of Unsymmetrical 2,3-Diarylindoles by Site-Selective Suzuki-Miyaura Reactions of N-Methyl-2,3-dibromoindole

Synlett (2010)

Peter Langer Muhammad Zainal Ibad Munawar Hussain Obaid‐ur‐Rahman Abid Asad Ali

The Suzuki-Miyaura reaction of N-methyl-2,3-dibromoindole with two equivalents of boronic acids gave symmetrical 2,3-diarylindoles. The reaction with one equivalent of arylboronic acid resulted in site-selective formation of 2-aryl-3-bromoindoles. The one-pot reaction of 2,3-dibromoindole with two different arylboronic acids afforded unsymmetrical 2,3-diarylindoles containing two different aryl groups.
