This study investigated the efficacy of magnetic Sn metal–organic frameworks (MSn-MOFs) in removing insecticide amoxicillin (AMX) from aqueous solutions.
Abstract Copper can be susceptible to corrosion in acidic cleaning solutions for desalination system, especially if the solution is highly concentrated or process involves extended exposure acid. In current work, Aloe ferox Mill (AFM extract) used as a natural origin inhibitor copper 1.0 M HCl solution. The mitigation qualities of AFM extract were assessed by means electrochemical, gravimetric, and surface examinations. mixed-type inhibitor, based on polarization research findings....
The present research describes the design of robust electrochemical sensors based on electro-responsive molecularly imprinted polymer nanoparticles (e-MIPs). e-MIPs, tagged with a redox probe, combine both recognition and reporting functions. This system replaces enzyme-mediator pairs used in traditional biosensors. analyte process relies generic actuation phenomenon when conformation e-MIPs is changing response to presence template analyte. concentration measured using voltammetric methods....

According to system, examined surfactant is mixed-type inhibitor. an adequate inhibitor, evidenced reduction current densities rise coverage surface identified with evolving amount. When had added, capacitive cycle...
Electrochemical sensing of paracetamol in polluted water was achieved using facile-synthesized tungsten oxide nanoparticles.
Sitagliptin is a hypoglycaemic agent used to reduce blood sugar levels in patients with type 2 diabetes mellitus (T2DM). Real time monitoring of sitagliptin crucial prevent overdose, which might cause liver, kidney and pancreatic diseases. As an alternative solution, voltammetric sensor was fabricated using artificial receptors called electroactive molecularly imprinted polymer nanoparticles (nanoMIPs). The nanoMIP tagged redox probe (ferrocene) combines both the recognition reporting...
Screening drugs on the street and biological samples pose a challenge to law enforcement agencies due existing detection methods instrument limitations. Herein we present graphene-assisted molecularly imprinted polymer nanoparticle-based sensor for amphetamine. These nanoparticles are electroactive by incorporating ferrocene in their structure. particles act as specific actuators electrochemical sensors, presence of redox probe embedded structure allows non-electroactive In control approach,...
Biological consideration, with the effect of chromium, comes from its prominent impact on environmental pollution a toxic microbial organisms, plants, and mammals. High amounts chromium are discharged into different environments via industries such as dyeing printing in textile industries, chemical manufacturing, leather tanning, metal plating. The hexavalent ion [Cr(VI)] is known to be 500 times more compared Cr(III) cation. Herein, removal Cr(VI) wastewater antimicrobial or...
Our aims in this work are the preparation of an ionic liquid based on heterocyclic compounds with Ag nanoparticles and investigation its application as antibacterial anticandidal agent. These goals were achieved through fabrication 5-Amino-3-(4-fluorophenyl)-N-hexadecyl-7-(4-methylphenyl)-2-H spiro[cyclohexane1,2’-[1,3]thiazolo [4,5-b]pyridine]-6-carbonitrile (P16).

Abstract Many applications, including elbows of piping systems in pressurized water reactors, require ductile materials. However, the impingement solid particles entrained turbulent flows causes these materials to erode. To mitigate erosion failures, this paper proposes a low-cost method for predicting carrying gas-dominated and liquid-dominated flows. The solely relies on Computational Fluid Dynamics (CFD), drawing inspiration from experimental data 90-degree stainless-steel found...
