The production of strawberries ( Fragaria × ananassa ) in hydroponic systems has been increasing. In systems, precise nutrient management is crucial for optimal plant growth and fruit production. Among essential elements, potassium (K) a key that affects yield quality fruiting crops. objective this study was to investigate whether increasing the K concentration Yamazaki strawberry solution could enhance growth, yield, strawberries. Bare-root plants ‘Monterey’ ‘San Andreas’ were planted deep...
Arrays of blue (B, 400−500 nm) and red (R, 600−700 light-emitting diodes (LEDs) used for plant growth applications make visual assessment plants difficult compared to a broad (white, W) spectrum. Although W LEDs are sometimes in horticultural lighting fixtures, little research has been published using them sole-source lighting. We grew seedlings begonia (Begonia ×semperflorens), geranium (Pelargonium ×horturum), petunia (Petunia ×hybrida), snapdragon (Antirrhinum majus) at 20°C under six LED...
The global food system is and will be facing many challenges in the coming decades, which necessitate innovative solutions to address issues of a diminishing fertilizer supply, an increasing demand from growing populations, frequent extreme climates due greenhouse gas emissions. An advancement proposed synthesizing waste, here referred as waste anaerobic digestate (FWAD). This occurs through process digestion, where organic matter such contained environment allowed broken down by...
The use of metal nanoparticles, including Au, Ag, Cu, and Al, can increase the efficiency photovoltaic devices by electromagnetic field enhancement, which is driven excitation localized surface plasmon resonance. Direct energy conversion from light into electricity via decay plasmons causing hot electron-hole pairs also a feasible channel. generation electrons in nanostructures occur through intraband within conduction band or interband transition, caused transitions other bands to...
Abstract Crystalline titanium dioxide (TiO 2 ) (anatase and rutile) possesses a higher refractive index than amorphous TiO near‐zero absorption in the visible region, making them an ideal material for metasurfaces. However, fabrication limitations hinder their implementation into flat optics. In this work, wafer‐scale manufacturing platform is proposed crystalline Sol–gel developed as printable which its phase can be precisely controlled to produce amorphous, anatase, or rutile, depending on...
Abstract Metasurfaces have emerged as a rapidly advancing technology enabling easy‐to‐integrate planar photonic devices, owing to their exceptional control of light‐matter interaction at subwavelength scale. They offer unique optical functionalities for various applications, including medical imaging. Despite early successes, fixed capabilities and narrow operational bandwidths limit integration into advanced chip‐scale systems. Addressing the need ultra‐compact, high‐performance UV–Vis...
Abstract Plasmonic hot carriers have garnered considerable attention in photovoltaics and photocatalysis, yet their full potential is limited by the challenge of harvesting both positive negative polarity at same time. Here, an unprecedented plasmonic carrier device capable extracting types simultaneously demonstrated. This scheme involves generating harnessing electrons holes concurrently using a lateral Si p–n junction diode coupled to Ag nanoprisms. The experimental numerical results...
Strawberries ( Fragaria × ananassa ) are being produced increasingly in indoor vertical farms, where the light quality of sole-source lighting is a primary factor that influences outcomes crop production. Far-red (FR) (700–750 nm) has been shown to promote plant responses such as leaf expansion, biomass accumulation, and flowering some long-day species. However, impacts including FR on strawberries have not fully understood. This study investigated growth development ‘Albion’ ‘Monterey’ an...
Because hydroponic operations in the United States can be certified as organic, and because price of chemical fertilizers has increased, there is an increasing interest using organic beneficial microorganisms for controlled-environment agriculture. However, a scarcity information regarding their effectiveness application methodologies. We investigated effects inoculating Azospirillum brasilense Rhizophagus intraradices on growing lettuce ( Lactuca sativa ‘Cherokee’) tomato Solanum...

Beyond producing leafy greens, there is a growing interest in strawberry production on indoor vertical farms. Considering that sole-source lighting one of the most important components for successful crop production, we investigated how photosynthetic photon flux density (PPFD) and photoperiod affected plant growth, flowering, fruit ‘Albion.’ Bare-rooted plants were grown deep water culture hydroponics inside an farm at 21 °C under white + blue red light-emitting diodes PPFD 200, 300, or 450...
Although green (G, 500 to 600 nm) and far-red (FR, 700 800 light play important roles in regulating plant growth development, they are often considered less useful at stimulating photosynthesis than red (R, blue (B, 400 light. Based on this perception, approaches modifying the transmission of greenhouse glazing materials include (1) conversion G photons from sunlight into R (2) exclusion near-infrared (>700 fraction sunlight.
