Abstract Antibiotic resistance is currently becoming a more serious threat to global health, especially in severe nosocomial infections treatment by multidrug-resistant bacteria. This research provides new way of synergizing green-synthesis for zinc oxide quantum dots (ZnO-QDs with hexagonal crystals) that are 7nm diameter and zero-valent Ag cubic crystals 67 nm size embedded nitazoxanide substrate (NZ). Instrumental characterization like SEM, TEM, EDAX, FT-IR comprehensive antimicrobial studies were conducted study the incorporation behavior composites based on NPs/ZnO QDs/NAZ. combination has not been hitherto addressed anywhere else published literature, as well commercial viability. In this context, we have precisely tuned nanoparticle ratio designing formulation demonstrating potent activity against MDR infections. By employing scaffold careful decoration thereof potency unlocked overriding conventional therapies. addition, NPs/ZnO-QDs/nitazoxanide (G6) formula exhibited therapeutic efficacy span 96.15±1.68% 99.57±0.20% human post 48h incubation; breakthrough levels achieved our method. Accordingly, ZnO QDs/Ag NPs/NZ composite offered potential multidrug resistant pathogens trend revolutionizing treatment.

This groundbreaking research delves into the intricate molecular interactions between MXene and trihalomethanes (THs) through a comprehensive theoretical study employing density-functional theory (DFT). Trihalomethanes are common carcinogenic chlorination byproducts found in water sanitation systems. focuses on pristine [Mn+1·Xn] monolayer its various terminal [Tx] functional groups [Mn+1·XnTx], strategically placed surface for enhanced performance. Our investigation involves detailed analysis of adsorption energies THs different types, with MXene-Cl layer emerging as most compatible variant. specific exhibits remarkable properties, including total dipole moment (TDM) 12.443 Debye bandgap 0.570 eV, achieved meticulous geometry optimization computational techniques. Notably, such trichloromethane (CHCl3), bromide-chloromethane (CHBrCl2), dibromochloromethane (CHBr2Cl) demonstrate highest TDM values, indicating substantial changes electronic optical parameters, values 16.363, 15.998, 16.017 Debye, respectively. These findings highlight potential an effective adsorbent detector CHF3, CHClF2, CHCl3, CHBrCl2, CHBr2Cl. Additionally, we observe proportional increase energy, indicative conductivity, termination atom combinations, Mxene-O-OH, Mxene-O-F, Mxene-O-Cl, Mxene-OH-F, Mxene-F-Cl, Mxene-OH-Cl, measured at 0.734, 0.940, 1.120, 0.835, 0.927 Utilizing DFT, elucidate surfaces. results conclusively significant influence nature quantity MXene’s primitive value. contributes to our understanding MXene–THs interactions, offering promising avenues development efficient adsorbents detectors THs. Ultimately, these advancements hold revolutionize practices enhance environmental safety.

With the development of proton exchange membrane fuel cells (PEMFCs), foam metals with lightweight advantages and highly porous structures have become promising flow field materials to replace traditional carbon plates. However, in operating environment high temperatures acid situation, metal suffers severe corrosion issues. To solve this problem, Sn Sn/graphene composite coatings are prepared physical characteristics analyzed by X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM). Tafel polarization test, potentiostat electrochemical impedance spectroscopy used test resistance coated nickel a PEMFC cathodic environment. Compared Sn-coated foam, is further enhanced addition graphene. The coating obtained electrodeposition at current density 15 mA·cm–2 has lowest density, which accounts for only 41.20% 33.48% uncoated value 50°C 80°C, respectively. Since maximum 38.99 Ω·cm². potential -0.22 mA constant test. After an 8h no noticeable pitting behavior shown on surface because compact coating.
