The aim of this study is to create TiO2 coating on the tile substrate using cell-gel and immersion method. Initially, TiO2 coating was prepared by sol gel method and then, deposition was performed in three stages with different immersion periods of 20, 40 and 60 s and finally, the samples were calcined at 450 °C. The phases and microstructural characteristics of the samples were analyzed using ...
Aloe vera gel is a polysaccharide widely used as an edible coating because it contains glucomannan and lignin compounds that can inhibit respiration transpiration in fruit. However, aloe has weakness such easy to change its color, odor, viscosity. Therefore, stabilizer needed, one of which gum arabic. Storage temperature also affects the stability gel. The purpose this study was determine conce...
Abstract The technology that is commonly used to control postharvest pathogen attacks coating with synthetic chemicals, but this has an unfriendly impact on the environment and consumers. Coating A. vera L gel plant extracts a natural way extend shelf life maintain quality. research was focused finding composition of guava fruit . indica leaf extract provided physicochemical properties optimal ...
Background: Nowadays, the surface modification of biomaterials to increase biocompatibility and improve other aspects of environmental performance is widely prevalent and is developing. Biological host response depends on the primary interactions of biological and biomaterials systems at the molecular surfaces. Therefore, the surface properties at the atomic scale influence on compatibility and...
This paper reports on a rapid new method for in-situ sol-gel deposition of silica layers in PDMS microchannels. A two-step process is used; first allowing TEOS to diffuse briefly into the channel, followed by acid catalysed hydrolysis and condensation. The silica coating results in an increased and stabilised electroosmotic flow. With this novel method there is no need for pretreatment of the m...
The addition of ZrO2 particles to the HA coating has received considerable attention because ZrO2 particles increase the bonding strength between HA coating and substrate. In this study, nanostructured hydroxyapatite (HA)/yttria stabilized zirconia (YSZ) coatings were prepared by a sol–gel method. It was found that at 950ºC, the dominant phases were HA and tetragonal (t)-zirconia in 3YSZ, cubic...
An experiment was conducted on the effect of edible coating shelf-life enhancement papaya (Carica L.) at ambient conditions. The main aim this study to increase shelf life by using coating. Postharvest losses in fruits is a serious problem due rapid deterioration during storage. Use coatings over used improve their quality and enhance life. purpose assess aloe vera gel, beeswax, paraffin wax ge...
Zirconium and its alloys have many applications in orthopedic medicine and compared to stainless steel, titanium and other metals used in the manufacture of implants has higher strength and corrosion resistance. Research shows that the method of preparation and surface modification before coating process has a significant impact on improving the metal implants among which include the sandblasti...
