TL;DR: Transparent conductors (TCs) have a multitude of applications for solar energy utilization and for energy savings, especially in buildings as discussed by the authors, which leads naturally to considerations of spectral selectivity, angular selectivity, and temporal variability of TCs, as covered in three subsequent sections.

TL;DR: In this paper, the photocatalytic degradation of malic acid was investigated on several rigid substrates, including glass and stainless steel, and the resulting materials have been characterized by XPS, SEM/EDX, XRD and UV-vis absorption spectroscopy.
Abstract: In the present study TiO 2 has been supported on several rigid substrates. Deposition on glass and quartz was carried out by a dip coating procedure and the deposition on stainless steel by an electrophoretic deposition process. The resulting materials have been characterized by XPS, SEM/EDX, XRD and UV-vis absorption spectroscopy. The materials were then tested for the photocatalytic degradation of malic acid. For this reaction, the sample supported on quartz showed the highest catalytic activity. The photocatalytic activity pattern as a function of the nature of the support (fused silica, glass, stainless steel) followed the decreasing order: TiO 2 /quartz > TiO 2 /steel ≈ TiO 2 /glassaphotolysis. This decline in activity has been correlated with the presence of cationic impurities (Si 4+ , Na + , Cr 3+ , Fe 3+ ) in the layer as a consequence of the necessary thermal treatments to improve the cohesion of the titania layer and its adhesion onto the support.

TL;DR: Ortiz and Gioia as discussed by the authors reviewed some recent developments based on the use of direct methods of the calculus of variations which have proven useful for understanding the mechanics of folding of thin films.
Abstract: In this article, we specifically concern ourselves with the buckling-driven delamination mechanism, whereby a portion of the film buckles away from the substrate, thereby forming a blister (also termed buckle or wrinkle). Blisters may grow by interfacial fracture, a process which, under the appropriate conditions, may result in the catastrophic failure of the component. Blisters are often observed to adopt convoluted-even bizarre shapes and to fold into intricate patterns. A principal objective of this article is to review some recent developments based on the use of direct methods of the calculus of variations which have proven useful for understanding the mechanics of folding of thin films (Ortiz and Gioia, 1994). These developments are reviewed in Section III, which is extracted from the original publication. The remaining sections are devoted to the application of these principles to the problem of predicting the shape of thin-film blisters.

TL;DR: In this article, the authors describe transparent glass window structures of the type bearing a coating of infra-red reflective material which is advantageously less than about 0.85 microns in thickness and wherein the observance of iridescence resulting from such a reflective coating is markedly reduced by provision of a very thin coating system beneath said infra red reflective coating.
Abstract: This disclosure describes transparent glass window structures of the type bearing a coating of infra-red reflective material which is advantageously less than about 0.85 microns in thickness and wherein the observance of iridescence resulting from such a reflective coating is markedly reduced by provision of a very thin coating system beneath said infra-red reflective coating. The thin coating system forms means to reflect and refract light to interfere with the observation of iridescence. A particular advantage of the invention is the ability of the thin coating system to be coated in a fraction of time presently required to coat anti-iridescent interlayers of the prior art.

TL;DR: A spectrally selective, glare-reducing mirror for vehicles which includes a substrate having a multi-layer coating on one side was proposed in this paper. But the results were limited to a blue reflecting mirror with luminous reflectance between about 35% and 60%.
Abstract: A spectrally selective, glare-reducing mirror for vehicles which includes a substrate having a multi-layer coating on one side. The multi-layer coating includes a thin, transparent dielectric layer, preferably of titanium dioxide at a thickness of about 600-650 angstroms, and a very thin layer of metal, preferably of aluminum or silver, at a thickness of between about 25 and 150 angstroms. The dielectric layer is closest to a source of incident light to be reflected by the mirror. When applied to the rear surface of a transparent substrate such as glass, the metal layer may also be coated with light absorbing material such as paint for protection and reduction in unwanted reflections. In the preferred dielectric and metal thicknesses, a blue reflecting mirror results having a glare-reducing luminous reflectance between about 35% and 60%, while costs are reduced due to lesser required amounts of metal than in prior known mirrors.
