Levofloxacin antibiotic is frequently being detected in the environment and regarded as an emerging contaminant. The present study was focused on green synthesis of magnetite (Fe3O4 - gINPs) nanoparticles from Moringa olifera its efficiency for removal levofloxacin aqueous solution. adsorbent (Fe3O4) were prepared by using coprecipitation method. Characterizations analyses both chemically synthesized performed SEM, XRD, FTIR. average crystallite size gINPs 14.34 nm 18.93 nm. performance...
High entropy alloys (HEA) are an emerging class of metallic materials that have shown the potential to outsmart conventional alloy systems in terms different physical and mechanical properties. Development eutectic microstructure high can help obtaining even better combination properties due fine distribution phases. Eutectic been developed present study by addition tantalum CoCrFeNi system. Pseudo binary phase diagram CoCrFeNi–Ta was calculated with Thermocalc software. Different...
The present study focused on investigating the effect of titanium dioxide nanoparticles (TiO2NPs) rice (Oryza sativa L.) growth and changes in soil health two contrasting textures (silt-loam clay). Moreover, response to different methods TiO2NPs application phosphorous fertilizer levels were also evaluated. For toxicity assessment, pot experiment was carried out. (0, 500, 750 mg kg−1) applied plants grown till vegetative stage. After harvesting, physiological parameters, stress assay,...
Microstructural development and mechanical properties of tungsten heavy alloy, WHA, with FeNiCoCrMn high entropy HEA, binder were investigated compared to conventional WHA using Fe–Ni binder. Both WHAs, HEA binders, fabricated by hot isostatic pressing at a temperature 1450 °C in an argon environment. Scanning electron microscopy revealed that binders possessed uniform well-refined microstructures. Energy dispersive spectroscopy X-ray diffraction, XRD, validated the formation composition...
AISI 4340 and 4140 are normally used for different structural applications in quenched tempered state due to their high strength, abrasion fatigue resistance but they lack toughness. Presence of dual phase microstructure such as ferrite-bainite ferrite-martensite steels have been reported improve toughness at the cost strength. It is believed that development bainite-martensite may help obtaining better combination mechanical properties. In this research work, has carried out austempering...
High entropy alloys (HEAs) are a relatively new class of material that have shown the potential to exhibit excellent combinations mechanical properties. Various microstructural modifications been explored further enhance their properties for use in demanding structural applications. The main focus present work is an investigation effect adding varying amounts hard ceramic (WC) tough HEA matrix (CoCrFeNi) by arc melting under argon atmosphere, including changes, and evaluation WC additions on...
Titanium foams have potential applications in orthopedic and dental implants because of their low elastic modulus good bone in-growth properties. In the present study, a novel method for preparation three-dimensional interconnected microporous titanium has been developed. This is based on insertion filler metal into by arc melting, followed its removal an electrochemical dealloying process development foams. Complete was confirmed X-ray diffractometry (XRD) analysis, whereas scanning...
The phase equilibria and thermodynamic properties of the Mo–Re system are studied by combining first-principle CALPHAD approach. mixing enthalpies in bcc hcp solution phases estimated calculations using special quasirandom structures. liquid, described a substitutional model. intermetallic phases, σ χ, with compound energy formalism with, respectively, 5 4 sublattices (SL) formation all end-members directly from ab initio calculations.

The precipitation hardening is widely applied to strengthen Al alloys. Here, we report an alternative way achieve high-strength alloys via forming the dislocation gradient through pre-torsion. Remarkably, exhibit a sharp increase in ultimate tensile strength up 605 MPa yet nearly without reducing uniform elongation, thereby outperforming their counterparts. superior strength–ductility combination ascribed excellent strengthening and strain effects stemming from substantial...
CoCrFeNi is a well-studied face centered cubic (fcc) high entropy alloy (HEA) that exhibits excellent ductility but only limited strength. The present study focusses on improving the strength-ductility balance of this HEA by addition varying amounts SiC using an arc melting route. Chromium in base found to result decomposition during melting. Consequently, interaction free carbon with chromium results in-situ formation carbide, while silicon remains solution and/or interacts constituent...
Abstract Carbon dots are regarded as a brand new class of nanostructures in the carbonaceous family that have piqued curiosity researchers wide range bio applications. This work focuses on synthesis and characterization carbon dots, well their latent fingerprint detection antibacterial/antifungal capabilities. Highly luminous were prepared by optimizing simple hydrothermal carbonization settings at 180 °C for 12 h using lemon juice raw precursor. The resulting product was examined Fourier...
Waste wood biomass as precursor for manufacturing activated carbon (AC) can provide a solution to ever increasing global water quality concerns. In our current work, Melia azedarach derived phosphoric acid-treated AC (MA-AC400) was manufactured at laboratory scale.
