The objective of this study was to compare corrosion behavior in several titanium alloys with immersion in acidulated saline solutions containing hydrogen peroxide. Seven types of titanium alloy were immersed in saline solutions with varying levels of pH and hydrogen peroxide content, and resulting differences in color and release of metallic elements determined in each alloy. Some alloys were ...

Evaluation of hemic cell morphology in stained blood film may be the most important part of the hematologic evaluation of exotic animals. The blood film provides important information regarding red blood cell abnormalities, such as changes in cell shape and color, presence of inclusions, and, in the case of lower vertebrates, changes in the position of the cell nucleus. Stained blood film also ...

The scales of Morpho butterflies are covered with intricate, hierarchical ridge structures that produce a bright, blue reflection that remains stable across wide viewing angles. This effect has been researched extensively, and much understanding has been achieved using modeling that has focused on the positional disorder among the identical, multilayered ridges as the critical factor for produc...

We designed multilayer wavelength-selective reflector films by stacking thin-films of transparent polymer. The optimum structure of the multilayer is determined using a combination of characteristic matrix method and a version of genetic algorithm. Such multilayer films can be used in LCD devices to enhance the color saturation of the display. key words: optical design, multilayer, color enhanc...

In this work, we address the problem of having an accurate colorimetric characterization of a scanner for traditional positive film in order to guarantee the accuracy of the color information during the digitization of a movie. The scanning of a positive film is not an usual task, however it can happen for cultural heritage purpose. Art-movies, are often created and stored as positive-film in m...

biological packaging material based on obtained proteins from fish waste, are biopolymers that have the capability of biodegradable film formation. thus, purpose of this research is to study and investigate some of films’ physical features made from trout fish myofibril protein. the film forming solution containing 1.5%, 2% and 2.5%(w/v)myofibril protein isolate of 100ml solution and glycerol a...

thyme essential oils (eo) with antimicrobial and antioxidant properties are widely used in pharmaceutical, cosmetic, and perfume industry. it is also used for flavoring and preservation of several foods. nowadays, packaging research is receiving a considerable attention due to the development of eco-friendly materials made from natural polymers such as starch and chitosan. in this study thymus ...
