The adaptable transmittance of electrochromic glazing allows to control the solar radiation entering buildings, yet level needed protect from glare is still an unanswered question. To bridge this gap, study evaluates visible light (? v ) required for blue-tinted low prevent discomfort when sun through glazing. Twenty participants were exposed four visual scenarios with varying viewing direction...

The vanadium-titanium black ceramic (VTBC) coating on all-ceramic solar collectors has both high absorptance (0.94) and emissivity (90%). However, the thermal conductivity of is very low (1.256 W/mK). To improve heat collection efficiency VTBC collectors, this paper establishes a mathematical model based energy-conservation relationships under steady-state conditions creates corresponding compu...

Homogeneously distributed zinc nanoparticles (NPs) on the glass substrate were investigated for the transmittance, mechanical durability, and antibacterial effect. The buffered Ti NPs between Zn NPs and glass substrate were studied for an enhancement of the transmittance and mechanical endurance. The Ti NPs buffered Zn NPs showed a high transmittance of approximately 91.5% (at a wavelength of 5...

Changes in intrinsic optical signals could be related to cell swelling; however, the evidence is not compelling. We measured light transmittance, ECS volume fraction (alpha), and extracellular K+ in rat spinal cord slices during electrical stimulation and the application of elevated potassium, NMDA, or anisoosmotic solutions. Dorsal root stimulation (10 Hz/1 min) induced an elevation in extrace...

Abstract The efficiency of both solar photovoltaic and thermal power generation is relatively low, with the maximum panel temperature conventional PV/T modules reaching 68.4 °C at noon, average electrical only 12.98%. In this paper, energy performance a module based on SiO 2 nanofluid was studied. Firstly, three different types nanofluids, mass fraction 0.3%, 0.5%, 0.7%, were prepared tested fo...

Vanadium dioxide (VO2) is widely recognized as a thermochromic material with great potential for application in smart glazing energy-efficient buildings. The monoclinic (M1) VO2 phase undergoes first-order reversible transition from the semiconductor to rutile metallic state. In this study, an M1 porous film was synthesized via polymer-assisted sol-gel route. Processing parameters, such drying ...

An experimental setup and procedure for accurate transmittance measurements of candidate filters for the Auger Fluorescence Detector is presented. For this check, we used the Hitachi U-2000 double-beam spectrophotometer (Sph) of the Chemical Department of the University of Athens (UoA). After the calibration of the Sph, we are able to observe transmittance deviations over the area of the filter...

In this paper the transmittance of metal-insulator-metal (MIM) waveguides containing semi-circular ring shaped and rectangular ring shaped grooves are investigated. By varying groove parameters their effects on the transmittance of the MIM waveguides are investigated. The results show that the transmittance spectra of the waveguides have maximum and minimum points, and by using appropriate para...

Transmittance spectra of fungi were estimated from seven-band optical micrographs. An optical microscope adjusted with a single-chip CCD camera with seven band filters was used for image acquisition. The Wiener method was applied to estimate the transmittance spectra of five species that belong to one genus of fungi. The Wiener estimation operator was calculated from transmittance spectra of 16...
