Layered metals as polarized transparent conductors

Philip Johannes Walter Moll, Maja Deborah Bachmann, Matthias Carsten Putzke, Chunyu Guo

The quest to improve transparent conductors balances two key goals: increasing electrical conductivity and increasing optical transparency. To improve both simultaneously is hindered by the physical limitation that good metals with high electrical conducti ...

Effect of window glazing color and transmittance on human visual comfort

Marilyne Andersen, Jan Wienold, Sneha Jain

: Occupants’ visual comfort in an indoor space strongly depend on the quantity and quality of the daylight inside the space which can be altered with the type of window glazing. In this study, we compared the visual comfort perception of participants with ...

Electrochromic windows allow for an improved management of solar heat gains in buildings and enhanced visual comfort of building users. All-solid-state electrochromic devices can be especially durable. During their fabrication lithium has to be inserted, p ...

ELSEVIER SCIENCE SA2021

Conventional selective low-e coatings for windows of residential buildings have a cut-off frequency in the near infrared spectral region NIR, limiting the resulting solar heat gain coefficient to g ≈ 0.5. By structuring the coating into nanomeshes, the sel ...

Behind electrochromic glazing: Assessing user's perception of glare from the sun in a controlled environment

Jan Wienold, Caroline Karmann, Sneha Jain

The adaptable transmittance of electrochromic glazing allows to control the solar radiation entering buildings, yet the level of transmittance needed to protect from glare is still an unanswered question. To bridge this gap, this study evaluates the level ...

Optical gap and fundamental gap of oligoynes and carbyne

Holger Frauenrath, Jan Cornelius Brauer, Stephen Schrettl, Laurent Alexis Clément Vannay, Eric Albert Georges Bremond, Emmanuel Romaric Contal

The optoelectronic properties of various carbon allotropes and nanomaterials have been well established, while the purely sp-hybridized carbyne remains synthetically inaccessible. Its properties have therefore frequently been extrapolated from those of def ...

Color neutral nanocomposite nickel-tantalum oxide for electrochromic windows

Josef Andreas Schuler, Olivia Valérie Charlotte Bouvard

Electrochromic windows can darken on demand to limit the solar gains entering a building to reduce the risk of overheating, while preserving the view towards the exterior. Yet, the switching speed and contrast as well as the durability of commercial produc ...

Magnetic and optical properties in degenerated transition metal and Ga co-substituted ZnO nanocrystals

Reinis Ignatans

In order to study the influence of itinerant electrons on magnetic properties of transition metal substituted ZnO nanocrystals, nanopowders containing different amounts of Ga and fixed amounts of Fe, Ni and Mn ions were synthesized. The ions of different t ...
