Resumen
Este estudio introduce una nueva ventana inteligente multimodal (LHE-ED) que controla inteligentemente la luz visible, el calor del infrarrojo cercano (NIR) y el enfriamiento del infrarrojo de onda larga (LWIR). Esta ventana avanzada mejora la comodidad interior y la eficiencia energética en los edificios.
Área de la Ciencia:
- Ciencias de los materiales
- Diseño de edificios sostenibles
- Eficiencia energética
Sus antecedentes:
- Las ventanas inteligentes son cruciales para los edificios sostenibles, pero el control independiente de la luz visible, el calentamiento en infrarrojo cercano (NIR) y el enfriamiento en infrarrojo de onda larga (LWIR) sigue siendo un desafío.
- La regulación dinámica de la radiación multifuncional es necesaria para diferentes requisitos operativos y condiciones climáticas.
Objetivo del estudio:
- Desarrollar una ventana inteligente multimodal (LHE-ED) capaz de modular independientemente las bandas espectrales visible, NIR y LWIR.
- Para lograr un control preciso de la iluminación, la calefacción y el enfriamiento radiativo para mejorar la comodidad interior y el ahorro de energía.
Principales métodos:
- Se fabricó un nuevo electrodo PET/ITO/PB/Pt-NPs para la modulación en doble banda de la radiación visible y NIR a través de la inserción de iones y la electrodeposición.
- El electrocromismo y la emisión dinámica fueron manipulados para la modulación de tres bandas, creando seis estados eléctricos independientes.
- Se llevaron a cabo simulaciones energéticas de edificios para evaluar el rendimiento del LHE-ED frente al vidrio comercial de bajo contenido de E.
Principales resultados:
- El LHE-ED demostró una excelente selectividad de longitud de onda con △T_Vis = 41.24%, △T_NIR = 53.95%, y Δε_8-13μm = 0.35.
- Las simulaciones mostraron que el LHE-ED supera al vidrio comercial de bajo E en varias zonas climáticas.
- Se observaron reducciones significativas en las emisiones de CO2 (hasta 34,01 kg/m2 al año) y en el consumo de energía de HVAC (34,18% anual).
Conclusiones:
- El LHE-ED desarrollado ofrece una modulación espectral de tres bandas sin precedentes para ventanas inteligentes.
- Esta tecnología mejora significativamente la eficiencia energética y reduce el impacto ambiental en los edificios.
- El LHE-ED representa una solución de nueva generación para el diseño de edificios que ahorran energía y son respetuosos con el medio ambiente.

01:03IR Frequency Region: Fingerprint Region
1.1K
IR spectra are divided into two main regions: the diagnostic region and the fingerprint region. The diagnostic region of the spectrum lies above 1500 cm−1. The absorptions resulting from single-bond vibrations of the N–H, C–H, and O–H stretch at higher wavenumbers and appear on the left side of the spectrum. The stretching absorptions of the C≡C and C≡N occur between 2100–2300 cm−1. In contrast, those arising from stretching absorptions of the...

01:21Masonry in Cold and Hot Weather Conditions
133
In cold weather, masonry construction requires specific precautions to ensure mortar does not freeze before curing, as this can significantly weaken its strength and watertightness. Mortar temperature should be maintained between 60°F and 80°F to support proper hydration and curing. Below 40°F, mortar water must be heated, but should not exceed 120°F as high temperatures can reduce mortar's compressive and bond strength.

01:19IR Spectrum
1.2K
When infrared (IR) radiation passes through a molecule, the bonds stretch or bend by absorbing the radiation. This absorption creates the molecule's absorption spectrum, which is the plot of its percentage transmittance versus wavenumber.
Transmittance is defined as the ratio of the radiant power passing through a sample to that from the radiation's source. Multiplying the transmittance by 100 gives the percent transmittance (%T), which varies between 100% (no absorption) and 0%...

01:24Color Vision
695
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

01:15Sensory Modalities
1.5K
Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...

02:16Light Acquisition
8.6K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.
