“…Other techniques such as vent, fog, fan cooling systems, dehumidification, and regeneration process of liquid desiccant also improve glasshouse climatic control (Lefers et al, 2016;Rabbi et al, 2019;Samaranayake et al, 2020;White, 2014). However, the high cost of these solutions indicates that an innovative alternative technique of using low emissivity 'smart glass' film, should significantly reduce the costs while maintaining adequate climate control in glasshouses (Lin et al, 2020).…”

“…The special glass film materials are optically engineered in a nanometre-scale, adjusting light transmittance to allow for high potential of reducing energy cost in high technology greenhouses (Lin et al, 2020). The "smart glass" (SG) film ULR-80 blocks the majority of UV light and a proportion of far-red and red light, which can reduce energy load required for heating and cooling in a protected cropping situation (Chavan et al, 2020).…”

Optical films that alter light transmittance may reduce energy consumption in high-tech greenhouses, but their impact on crop physiology remains unclear. We compared the stomatal responses of Capsicum plants grown hydroponically under control glass (70% diffuse light) or smart glass (SG) film ULR-80, which blocked >50% of short-wave radiation and ~9% of photosynthetically active radiation (PAR). SG had no significant effects on steady-state (gs) or maximal (gmax) stomatal conductance. In contrast, SG reduced stomatal pore size and sensitivity to exogenous ABA thereby increasing rates of leaf water loss, guard cell K + and Cl - efflux, and Ca 2+ influx. SG induced faster stomatal closing and opening rates on transition between low (100 µmol m -2 s -1) and high PAR (1500 µmol m -2 s -1), which compromised water use efficiency relative to control plants. The fraction of blue light (0% or 10%) did not affect gs in either treatment. Increased expression of stomatal closure and photoreceptor genes in epidermal peels of SG plants is consistent with fast stomatal responses to light changes. In conclusion, stomatal responses of Capsicum to SG were more affected by changes in light intensity than spectral quality, and re-engineering of the SG should maximize PAR transmission, and hence CO2 assimilation.

Optical films that alter light transmittance may reduce energy consumption in high-tech greenhouses, but their impact on crop physiology remains unclear. We compared the stomatal responses of capsicum plants grown hydroponically under control glass (70% diffuse light) or smart glass (SG) film ULR-80, which blocked >99% of ultraviolet light and 19% of photosynthetically active radiation (PAR). SG had no significant effects on steady-state (gs) or maximal (gmax) stomatal conductance. In contrast, SG reduced stomatal pore size and sensitivity to exogenous ABA thereby increasing rates of leaf water loss, guard cell K+ and Cl- efflux, and Ca2+ influx. The transition between low (100 μmol m−2 s−1) and high (1500 μmol m−2 s−1) PAR induced faster stomatal closing and opening rates in SG relative to control plants. The fraction of blue light (0% or 10%) did not affect gs, but induced stomatal oscillations in SG plants. Increased expression of stomatal closure and photoreceptor genes in epidermal peels of SG plants is consistent with fast stomatal responses to light changes. In conclusion, light intensity was more critical than spectral quality for optimal stomatal responses of capsicum under SG, and re-engineering of the SG should maximize PAR transmission to maintain a better stomatal development.HighlightsCapsicum plants grown under SG film exhibit decreased stomatal pore area, higher water loss and reduced ABA-sensitivity.SG-grown plants have faster rates of stomatal closing and opening in response to light intensity changes.SG increases efflux of K+ and Cl- and influx of Ca2+ of guard cells.SG upregulated the expression of key genes involved in stomatal regulation and light sensing.

Far‐Field Excitation of Acoustic Graphene Plasmons with a Metamaterial Absorber

When a graphene sheet is placed near a metal surface, it supports a special type of highly confined and low‐loss electromagnetic mode called acoustic graphene plasmons (AGPs). AGPs squeeze infrared photons into extremely confined areas down to a subnanometric scale and provides a unique platform for strong light–matter interactions. However, the efficient excitation of AGPs is a challenge due to the large momentum mismatch between free‐space light and AGPs. With theoretical analysis and numerical simulations, it is shown that the far‐field excitation of AGPs is realized by integrating graphene in a metal–insulator–metal (MIM) metamaterial with magnetic resonance (MR). More than ten graphene plasmonic modes are excited in the midinfrared range, resulting in a multiresonant spectra with Fano‐like characteristics at each resonant wavelength. The proposal opens a new door to explore the strong plasmonic coupling between graphene and metallic metamaterials down to atomic scale for extreme nanophotonics. The potential applications range from ultracompact tunable metamaterials and ultrasensitive infrared spectroscopy to single‐molecule optics, quantum plasmonics, and others.
