Lately, the method of thermography is becoming an unavoidable method in non-destructive testing of different metal materials and constructions. The application of this method is found in testing the energy efficiency, deterioration of structural components, as well as testing the energy efficiency of housing units. Using the thermographic method it is possible to reduce the negative environment...

Beyond the materials and deposition process selection and development, there is the finished product, the coated optic. Testing standards for optical coatings have been used in practice for at least 45 years; they have been revised in the interim to accommodate improvements in coating and testing technology. This issue discusses how finished thin film optical coatings are examined and evaluated...

BACKGROUND This study was carried out as a prospective clinical field study with the aim of evaluating the clinical performance of Equia Fil® with a nanofilled resin coating and the conventional Fuji IX GP® fast with an LC coating according to the World Dental Federation (FDI) restoration material evaluation criteria. METHODS The clinical performance of Equia Fil® and Fuji IX GP® fast was eva...

Large-area subwavelength dielectric hexagonal lattices of cylindrical pillars on quartz substrates that provide high optical transmittance at all angles of incidence under different polarizations of light, and are fabricated using lowcost patterning techniques, are demonstrated and analyzed. Transmittance >85% for angles of incidence in excess of 70° is demonstrated at visible and near-infrared...

Sol-gel technique has been utilized for the fabrication of multifunctional inorganic-organic hybrid materials for specific applications. Synthesized methacrylic acid and benzoylacetone modified tin alkoxide precursors were used for the first time for the realization of directly UV-photopatternable antimony-doped tin dioxide coatings. These single-layered coatings have transmission values over 8...

The problems associated with organic solventborne coatings have provided an impetus for developing and utilizing alternative coatings. including waterborne. high solids. powder, and radiation-cured formulations. This paper addresses the technical, economic, and environmental implications of each alternative and discusses the constraints and benefits of using the alternative coatings.

This thesis describes the science and technology of a new class of autonomic polymeric materials which mimic some of the functionalities of biological materials. Specifically, we demonstrate an autonomic self-healing polymer system which can heal damage in both coatings and bulk materials. The new self-healing system we developed greatly extends the capability of self-healing polymers by introd...

Contemporary chemical and material engineering often takes inspiration from nature, targeting for example strong yet light materials and materials composed of highly ordered domains at multiple different lengthscales for fundamental science and applications in e.g. sensing, catalysis, coating technology, and delivery. The preparation of such hierarchically structured functional materials throug...

Superhydrophobic surfaces with the self-cleaning behavior of lotus leaves are sought for drag reduction and phase change heat transfer applications. These superrepellent surfaces have traditionally been fabricated by random or deterministic texturing of a hydrophobic material. Recently, superrepellent surfaces have also been made from hydrophilic materials, by deterministic texturing using phot...

Optical fibers are crucial in the field of telecommunications, offering the advantages of low loss. broad bandwidth, fine diameter, light weight, freedom from electromagnetic induction, freedom from crosstalk, and efficiency in resource consumption. In comparison to the copper conductors used in conventional telecommunications cables, however, they are at a disadvantage in terms of their low me...
