Green synthesis of aryl‐(4‐oxo‐1,2‐dihydroquinazolin‐4‐yl‐methylene) pyrazole‐TiO2 nanoparticles as dyes removable for waste water treatment

Facile synthesis for true intermediate (E)‐ and Z‐2‐(((5‐bromo‐1‐(3‐chloropyridin‐2‐yl)‐1H‐pyrazol‐3‐yl)methylene)amino)‐5‐chloro‐3‐methylbenzoic acid precursors and 2‐(5‐bromo‐1‐(3‐chloropyridin‐2‐yl)‐1H‐pyrazol‐3‐yl)‐6‐chloro‐3,8‐dimethylquinazolin‐4(3H)‐one (QPP) as electron donor/electron acceptor to be working as efficient dye sensitizers. These new derivatives have a wide‐band gap photo‐catalysts semiconductor and are performing to spread to the visible‐light region to give more stability and efficiency towards biomedicine for different diseases. In the present work, the authors are suggesting the design and synthesis of new structures of QPP molecule with extended visible light absorptivity due to the extended π‐π/n‐π conjugations, to stimulate TiO2 nanoparticles in visible‐light region. The physicochemical characterizations confirmed the successful synthesis of QPP, TiO2, and QPP II/TiO2 …

Low-Pressure Plasma as a Seed Coat to Enhance the Growth of Wheat Seedlings for Obtaining Future Outcomes Under Salinity Conditions

The increased drought and soil salinity are two effects of climate change that threaten global food security and food production. Soil salinity is a major challenge for agriculture in arid areas, creating conditions that may be unsuitable for the growth of crop plants. Here, we use recycled organic tree waste combined with low-pressure plasma treatment as grain coating to improve the ability of Egyptian wheat seeds (Misr-1 and Gemme-za-11) to survive, germinate and produce seedlings in highly saline soil. We coated the seeds with biofilms of lignin and hash carbon to form a protective extracellular polymeric matrix and then exposed them to low-pressure plasma for different periods of time. The effectiveness of the coating and plasma was evaluated by characterizing the physical and surface properties of coated seeds using X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), nuclear magnetic resonance (NMR) spectroscopy, and wettability testing. We also evaluated biological and physiological properties of coated seeds and plants they produced by studying germination and seedling vigor, as well as by characterizing fitness parameters of the plants derived from the seeds. The analysis revealed the optimal plasma exposure time to enhance germination and seedling growth. Taken together, our study suggests that combining the use of recycled organic tree waste and low-pressure plasma may represent a viable strategy for improving crop performance in salty environments.

A collisional global sheath–Bulk model of argon plasma for semiconductor scale manufacturing

Plasma processes enhance the high-quality, semiconductor fabrication employed in large-scale industries. A crucial element in this process are the many gases that generate different reactive species at low temperatures. Capacitive plasma discharge radio frequency CCPs play a major role in semiconductor scale fabrication. The analysis of nonlinear dynamics in CCPs are complicated even under simple approaches. Therefore, we study self consistent collision fluid model, particle in cell simulation PIC, step approximation and finally the global model to find the accurate solution of merging plasma sheath -bulk region. For this purpose we study the self consistent collisional fluid model to find the accurate charge–voltage distribution V(Q) which controls the nonlinear dynamics of CCPs. The results against the PIC simulations and the more elaborate model step approximation is accomplished with higher accuracy …

New achievement of the global sheath-bulk model for the collisionless radio-frequency using in scale industries

Plasma processing is extensively utilized in enormous industries products like semiconductor devices, textile fabrics, modifying polymers, and seed treatments. One of the most significant enhancements to this technology is the low pressure of capacitively coupled plasma (CCPs). Contrary to other plasma processes like atmospheric pressure plasma jet, low-pressure plasma under vacuum is the best choice for scale industrial applications, including etching, semiconductor IC fabrication, and seed processing for agricultural use. This is due to its full soft control and complete ionization chamber. It is quite difficult to analyze the dynamics of the plasma sheath theory. Despite being among the most relevant models, the step approximation model does not fully account for all nonlinear dynamics, particularly high harmonic effects, the particle density singularity between the sheath and bulk regions, and the absence of an …

Bio‐fuels production through waste tires pyrolytic oil upgrading over Ni‐W/zeolite composites derived from blast furnace slag

Waste tires is one of the solid residuals that can have serious impacts environmentally. Therefore, controlling this waste through conversion into value‐added products such as bio‐fuels is highly recommended. Consequently, this work reports catalytic‐hydrocracking of waste tire pyrolytic oil (WTPO) to fuels over Ni‐W supported on zeolite X and A. The zeolites were hydrothermally synthesized from another type of waste, namely blast furnace slag (BFS). The prepared samples were characterized by X‐ray diffraction (XRD) analysis. The successive synthesis of zeolites A and X could be detected through observing cubic and octahedral particles via scanning electron microscopy (SEM). The two prepared catalysts presented mesoporous natures with reasonable specific surface area, as acquired from nitrogen adsorption‐desorption analysis. The catalysts activity toward upgrading of WTPO was investigated under …

Cold Fusion Based on Matter-Antimatter Plasma Formed in Molecular Crystals

The main purpose of this work is to shed light on the possibility of producing huge amount of energy based on the construction matter-antimatter plasma in a molecular crystal. It is assumed that two beams of isothermal hydrogen and antihydrogen are injected into a palladium crystal leading to a plasma state composed of particles and antiparticles. The collapse of this state releases a huge amount of energy which can be used as fuel for space shuttles. Thus, the novel system of isothermal pressure interaction enhances the energy power carried out by the quantum ion acoustic soliton (QIAS). In addition to the energy power released from the particle-antiparticle annihilation. The probability of merging the energy from these two cases is available at certain condition. The released energy may be a significant step in solving the energy scape of Tokomak to produce fusion energy. The study starting from the one-dimensional quantum hydrodynamic model (in which the term of electron-positron and proton-antiproton for hydrogen-antihydrogen is included), a Korteweg de Vries equation (kdv) is derived, the QIAS energy experiences and the annihilation energy power are calculated. It is found that the total energy of QIAS and the energy resulting from hydrogen-antihydrogen annihilation are important step towards the establishment of a cold fusion power station.

Plasmas Created in the Interaction of Antiprotons with Atomic and Ionized Hydrogen Isotopes. Suggested Fuels for Space Engines

The main objective of the present work is to investigate the properties of plasmas created by injecting a thermalized beam of antiprotons in two types of media. The first is hydrogen, deuterium, or tritium atoms localized in palladium crystals. The second medium is composed of protons, deuterons, or tritons localized in a magnetic cavity. Particularly, it is demonstrated that huge amounts of energy are released in both cases which could be used as fuels for space shuttle engines. A novel mathematical scheme is employed to calculate the energy yields in real space at different incident energies of the antiprotons.

A green microwave method for synthesizing a more stable phthalazin-1-ol isomer as a good anticancer reagent using chemical plasma organic reactions

AbstractsConventional synthesis of the phthalazine has already allowed affording the phthalazin-1-one phthalazin-1-ol dynamic equilibrium that decreases the anticancer activity due to diminishing the concentration of the phthalazin-1-ol product. Nowadays, pure phthalazin-1-ol (5) can be gaining by using green microwave tools that increase the power of the phthalazine nucleus as an anticancer drug. A microscopic thermal kinetic parameter like activation energy and the pre-exponential factor of the chemical plasma organic reactions affording pure phthalazin-1-ol (5) is calculated by using DFT simulation is obtained. Then we fed these parameters into the exact Arrhenius model to evaluate the distribution of chemical equilibrium conditions for producing phthalazin-1-ol. The proposed novel models that matching between microscopic and macroscopic show that the thermal stability of the equivalent temperature of …
