Highly transparent and luminescent CaMoO4:Eu/Ag composite films were fabricated on glass substrates as multifunctional antireflective (AR) coatings. The films were deposited through a combination of a sol–gel dip-coating technique and a hot water treatment. With the addition of an aluminum source in coating solutions, the sol–gel-derived films underwent a remarkable microstructural change durin...

This paper reports the effects of the seed layers prepared by spin-coating and dip-coating methods on the morphology and density of ZnO nanowire arrays, thus on the performance of ZnO nanowire-based dye-sensitized solar cells (DSSCs). The nanowire films with the thick ZnO buffer layer (*0.8–1 lm thick) can improve the open circuit voltage of the DSSCs through suppressing carrier recombination, ...

This study reports on the development of bio-based hydrophobic coatings for packaging papers through deposition of polyhydroxybutyrate (PHB) particles in combination with nanofibrillated cellulose (NFC) and plant wax. In the first approach, PHB particles in the micrometer range (PHB-MP) were prepared through a phase-separation technique providing internally-nanosized structures. The particles w...

The sol-gel method provides a wide variety of applications in the medical field. One these is formation coatings on metal implants. containing specific additive can enhance or improve existing surface properties substrate. In this work, titania were doped with two forms silver (AgNO3, Ag3PO4) and synthetic hydroxyapatite applied titanium samples by dip-coating technique. After drying slow firin...

In this work, the characteristic properties of the lubrication approximation are studied and its weak ellipticity is established, in contradistinction to the commonly accepted parabolic character of the lubrication equations resulting from the underlying unidirectional flow assumption. The weak ellipticity property allows the lubrication analysis to capture flow topologies around stagnation poi...

the aim of the current study was to design a porous osmotic pump–based drug delivery system for controlling the release of buspirone from the delivery system. the osmotic pump was successfully developed using symmetric membrane coating. the core of the tablets was prepared by direct compression technique and coated using dip-coating technique. drug release from the osmotic system was studied us...

This work aims to develop and compare two types of conductive, polymer-based coatings via a dip coating process. The first type of coatings was made by dispersing and incorporating carbon black (CB) nanoparticles in a poly(methyl methacrylate) (PMMA) solution followed by dip coating. The CB content and dipping parameters were varied to explore their effects on the particle dispersion, coating t...

This paper reports the improvement in the sensing performance of nanocrystalline SnO(2)-based liquid petroleum gas (LPG) sensors by doping with fluorine (F). Un-doped and F-doped tin oxide films were prepared on glass substrates by the dip-coating technique using a layer-by-layer deposition cycle (alternating between dip-coating a thin layer followed by a drying in air after each new layer). Th...
