The rapid developments in molecular sciences like nanotechnology and self-organizing molecular systems generate a wealth of new materials and functions. In comparison to electronics the application in architecture remains somewhat underexposed. New functionalities in optics, responsive mechanics, sensing and adjustable permeation for gases and water might add to new opportunities in providing f...

OBJECTIVE To evaluate plasma-enhanced, chemically vapor deposited (PECVD) amorphous silicon carbide (α-SiC:H) as a protective coating for retinal prostheses and other implantable devices, and to study their failure mechanisms in vivo. APPROACH Retinal prostheses were implanted in rats sub-retinally for up to 1 year. Degradation of implants was characterized by optical and scanning electron mi...

Amorphous SiO2 thin films are one of the two components highly reflective mirror coatings gravitational-wave detectors. For this study, layers amorphous on crystalline Si substrates were produced by ion-beam sputtering (IBS), using accelerated neutralized argon ions as particles, is case for actual The aim study to investigate possible presence various defects in materials order improve coating...

Reversible, nonvolatile, and pronounced refractive index modulation is an unprecedented combination of properties enabled by chalcogenide phase-change materials (PCMs). This makes PCMs a fast-growing platform for active, low-energy nanophotonics, including tunability to otherwise passive thin-film optical coatings. Here, we integrate the PCM Sb2Se3 into novel four-layer coating that exploits ph...

Brownian motion of the coating layers on a test mass is one of the limiting noise sources for high precision measurements such as gravitational-wave detection [1] or cold damping experiments [2]. Thermal noise is also the most significant source of the environmental decoherence that prevents us to observe quantum behavior of a macroscopic object [3]. Reduction of classical noise is a key for va...

Most of the pitched roofs of existing buildings in Europe are covered by non-white roofing products, e.g., clay tiles. Typical, cost effective, cool roof solutions are not applicable to these buildings due to important constraints deriving from: (i) the owners of homes with roofs visible from the ground level; (ii) the regulation about the preservation of the historic architecture and the minim...

The present study is aimed at investigating the relationship among Iranian EFL teachers’ reflective teaching, reflective thinking and classroom management ability. To this purpose, 102 male and female EFL teachers, aged between 25 and 40, with different academic background who were teaching at different levels, were chosen to fill in three questionnaires on reflective thinking, reflective teach...

this study examined the effects of cooperative learning techniques (clt) on vocabulary achievement of reflective/impulsive iranian efl learners. from among 130 students at fajr institute in dehdasht, kohkiloyeh and boyer ahmad province, iran, 90 participants were selected based on their performance on the oxford placement test (opt). the participants were then divided into two experimental grou...

Environmental stability studies for thin-film coating materials employed on the upgraded OMEGA laser system are essential for defining acceptable air humidity levels and their control, as well as for facilitating proper thin-film coating design of long-term-use OMEGA laser optics. Moisture penetration into porous, dielectric thin-film coatings causes generally undesirable changes in the film's ...
