Enhancing the response to visible light and inhibiting recombination of photogenerated electrons and holes is a key point for strongly improved self-cleaning performances of TiO₂ self-cleaning films. In this work, TiO₂ thin film doping with three different ions (Fe, Al, Ce) on glass substrate respectively by sol-gel method to explore the effect of ions on self-cleaning performance of TiO₂ thin films. All the prepared samples are characterized by XRD, SEM, UV-Vis and water contact angle tester. Moreover, the self-cleaning mechanism of doping TiO₂ thin film is discussed. The water contact angle of TiO₂ thin film doping with 9% Fe (molar ratio), 5% Ce and 5% Al are reach at 0°, respectively. In comparison with the water contact angle of pure TiO₂ thin film (2.5°), TiO₂ thin film doping with metal ions exhibit better self-cleaning property.

Background: This study estimated the cost of providing free maternal and child health (MCH) services at the primary health centre (PHC) level in southeast Nigeria. The costs of providing an essential benefit package of maternal and child health (MCH) services are unknown. Such information is required for optimal resource allocation decisions and for replicating similar programmes in different settings.

Designing efficient Ruthenium-based catalysts as practical anodes is of critical importance in proton exchange membrane water electrolysis. Here, we develop a self-assembly technique to synthesize 1 nm-thick rutile-structured high-entropy oxides (RuIrFeCoCrO) from naked metal ions assembly and oxidation at air-molten salt interface. The RuIrFeCoCrO requires an overpotential of 185 mV at 10 m A cm and maintains the high activity for over 1000 h in an acidic electrolyte via the adsorption evolution mechanism.

A dual-therapy sirolimus-eluting and CD34+ antibody-coated Combo Stent (DTS) has been developed to enhance endothelization and capture endothelial progenitor cells; however, vessel responses following DTS implantation remain unclear. Therefore, we evaluated early- and mid-term intravascular characteristics of DTS using intravascular imaging modalities. This multicenter, prospective, observational study enrolled 88 patients (95 lesions) who underwent DTS (43 patients, 48 lesions) or sirolimus-eluting Orsiro stent (SES, 45 patients, 47 lesions) implantation.

TEMPO-CNF film modified by two-dimension transition metal MXene has certain antibacterial properties. However, the problem of long-lasting stability greatly restricts the feasibility of long-term use of the composite film. Here, we introduced polyaniline (PANI) as a modifying molecule, which was electrostatically adsorbed on the surface of the MXene nanosheets to prevent its self-stacking and delay its oxidation.
