The purpose of this study was to evaluate the translucency and color change of simulated heavily discolored teeth using polymer-based dental tooth coating materials and flowable resin composites. Five shades of coating material and two shades of flowable resin composite were used. Colorimetric values of the materials in different shades were determined using the L*a*b* system of the Commission ...

We report using doctor-blading to replace conventional spin coating for the deposition of the hole-transport material spiro-OMeTAD (2,20 ,7,70-tetrakis-(N,N-di-p-methoxyphenylamine)-9,90-spirobifluorene) in solid-state dye-sensitized solar cells. Doctor-blading is a roll-to-roll compatible, large-area coating technique, is capable of achieving the same spiro-OMeTAD pore filling fraction as spin...

Water soluble polymers such as Hydroxy Propyl Methyl Cellulose (HPMC), Poly Vinyl Pyrrolidone (PVP), Carboxy Methyl Cellulose Sodium (CMC Na), and Methyl Cellulose as well as in combination of varying proportions are used in this study for the protective coating of Microcrystalline Hydroxy Apatite Complex (MCHC). The objective of this study was to investigate the effect of aqueous film coating ...

It is demonstrated that water-soluble, glucosylated poly(pentafluorostyrene) derivatives revealed favorable coating material properties for magnetic iron oxide nanoparticles. To prepare the coating material in high reproducibility and purity as well as in sufficient amounts, a new route of synthesis is established. The preparation and characterization of the glucosylated, tetrafluorostyryl mono...

The most promising method for enhancing solubility, therefore promoting the rate of dissolution is the formation of liquisolid compacts.[2]With Liquisolid technique as described by Spireas liquid formulations such as solutions or suspensions of poorly soluble drugs in a non-volatile liquid vehicle are converted into acceptably flowing and compressible powders, by simple physical blending with s...

There is a growing interest in fibers supporting optoelectrical properties for textile and wearable display applications. Solution-processed electroluminescent (EL) material systems can be continuously deposited onto fiber or yarn substrates in a roll-to-roll process, making it easy to scale manufacturing. It is important to have precise control over layer deposition to achieve uniform and reli...

Modern gas turbine hot sections need to be protected from elevated temperature and damaging environments. This protection starts as a typically two layer coating system, the base layer or bond coat (BC) acts as a corrosion barrier and a kind of buffer for the thermal mismatch between the base material and the second top thermally protective layer or Thermal Barrier Coating (TBC). The BC is norm...

The Li2TiO3-coated LiNi0.5Co0.2Mn0.3O2 (LTO@NCM) cathode materials are synthesized via an in situ co-precipitation method followed by the lithiation process and thermal annealing. The Li2TiO3 coating layer is designed to strongly adhere to the core-material with 3D diffusion pathways for Li(+) ions. Electrochemical tests suggest that compared with pristine NCM, Li2TiO3 serves as both a Li ion c...

STATEMENT OF PROBLEM Intraoral scanners may use proprietary acquisition and manufacturing processes. However, limited information is available regarding their accuracy, their precision, and the influence that refraction or coating may have on their output. PURPOSE The purpose of the study was to evaluate the scanning accuracy and precision of 4 intraoral scanners and to assess the influence o...

introduction one of the limitations of tissue conditioners (tc) is gradual hardening of the material in a short time period after insertion in the mouth, due to the loss of their viscoelastic properties. the aim of this study was to determine the softness of two different tissue conditioners with and without the monopoly coating. methods and materials in this experimental study, acropars and vi...
