The superhydrophobic silica coating has a great performance of self-cleaning which can be applied in the field of energy saving, anti-icing, drag reduction, etc. In this paper, Trimethyltrimethoxysilane (MTMS) /Trimethylchlorosilan (TMCS) superhydrophobic silica coating with two-layer structure was dip-coated. Atomic force microscope (AFM) images show that the surface morphology of MTMS/TMCS si...

Superhydrophobic self-cleaning surfaces were produced with simultaneous wide-angle optical transmittance in the near-infrared region and antireflection properties from combination of multi-scale surface topology based on silica nanoparticles, index grading and interference.

OBJECTIVES The aim of the study was to determine whether self-reported occupational exposure to cleaning/disinfecting agents in hospital workers is accurate, in comparison to expert assessment, taken to be the gold standard. METHODS In the Epidemiological Study of the Genetics and Environment of Asthma (EGEA), participants were interviewed on occupation with a specific questionnaire for hospi...

objective: the aim of this study was to evaluate and compare the cleaning ability and instrumentation time of manual and rotary methods used for preparation of primary anterior teeth. materials and methods: forty-four primary anterior teeth were used in this experimental study. access cavities were prepared and india ink was injected into the canals. the samples were divided into three groups a...

AIM The aim of this study was to assess whether oral hygiene-related self-efficacy is correlated with current oral hygiene and might influence the outcome of oral hygiene instruction. MATERIALS AND METHODS Hundred and twenty-six patients filled out questionnaires about oral hygiene-related self-efficacy, general self-efficacy, oral hygiene-related knowledge and demographic variables. Plaque a...

The present paper focuses on the investigation of self-cleaning properties based on studding of water repellency and blood repellency for TiN- and CrN single-layer and TiN/CrN nanoscale multi-layer coatings deposited via Cathodic Arc Evaporation (CAE) method on medical grade 420C stainless steel substrate. X-ray diffraction (XRD) method and Field Emission Scanning Electron Microscope (FESEM) wa...

Here, in situ synthesis of nano zinc oxide, along with aminolysis of polyester fabric, has simultaneously been carried out by using triethanol amine (TEA) and zinc acetate. The ZnO nano particles (NPs) were formed and stabilized on the fabric surface by amine compound at 130 °C for 1 h. The synthesis of nano ZnO particles on the polyester fabric were confirmed by X-ray diffraction (XRD) pattern...

Declaration of interest None. The asylum movement of the 19th century could be regarded as part of a state-guided sanitary movement to cleanse society of the harmful impact of those with mental illness. Although stigmatisation and fear were instrumental in this process, there is now strong evidence for genuine adverse outcomes of schizophrenia on society. Deinstitutionalisation and community ca...
