This study was performed to improve the techniques used for tenderizing red meat as elderly food. Beef meat was immersed in liposome encapsulated enzyme solution and the effect of protease encapsulation on the beef properties was analyzed. The protease encapsulation properties were analyzed according to the size distribution and enzymatic activity. After enzyme reaction on the beef, the chemica...

3D printing using thermoplastics has become very popular in recent years, however, it is challenging to provide a metal coating on 3D objects without using specialized and expensive tools. Herein, a novel acrylic paint containing malachite for coating on 3D printed objects is introduced, which can be transformed to copper via one-step laser treatment. The malachite containing pigment can be use...

Porcelain enamel is an inorganic-type coating, which applied to metals or glass for both decorative and functional purposes. This coating a silica-based solidified mass obtained by high-temperature firing (temperature can range between 450 1200 °C depending on the substrate). coatings differ from ceramic mainly their structure dilatation coefficient, organic paints inorganic nature of matrix ch...

The problem emerging from particle coating is how to manufacture particles with just enough material deposited to achive the desired result [1]. Especially in case of functional coatings, the uniformity of coating thickness over the entire particle surface plays an important role. In our study the performance of two bottom spray coaters and the effect of the particle motion on the coating unifo...

nanostructured alumina thin films were coated on stainless steel by sol-gel dip coating method. in order to prevent crack formation, al2o3 films were kept in a solvent bath immediately after coating to reduce the rate of drying. effects of calcination temperature and withdrawal speed on structural properties were analyzed using xrd and sem. topography and thickness of coatings were analyzed by ...

BACKGROUND Various surface coatings have been developed over the past decades to enhance fixation of cementless total knee arthroplasty (TKA). BIOFOAM(®) (MicroPort Orthopedics Inc., Arlington, TN, USA) is a novel cancellous titanium surface coating intended to increase both initial and long-term fixation. The purpose of this study was to investigate the early functional and radiographic outcom...

simple and economic coating monitoring technology. The light-emitting properties of the novel coating can serve as an indicator layer, which warns when the coating has worn off, replacing or recoating is necessary [7]. When we inspect on coating with a hand-held UV-lamp, the yellowgreen light of SrAl2O4:Eu, Dy3+ will disappear. It means that the functional coating is worn out and that recoating...

Coatings with specific surface wetting properties are of interest for anti-fouling, anti-fogging, anti-icing, self-cleaning, anti-smudge, and oil-water separation applications. Many previous bioinspired surfaces are of limited use due to a lack of mechanical durability. Here, a layer-by-layer technique is utilized to create coatings with four combinations of water and oil repellency and affinit...

the aim of this work is to synthesize and investigate the performance of yttria-doped zirconia solgelcoatings in the chemical corrosion prevention of zircaloy-4 (zirconium alloy) in a 1 n h2so4environment. the influence of four different molar ratios of water to alkoxide, namely 1, 4, 12, and20, on the coating quality and its corrosion prevention performance was investigated. differentialtherma...
