Butea monosperma, crown of thorns, red lantana camara and royal poinciana flowers extract as natural dyes for dye sensitized solar cells with improved efficiency

Advancements in lanthanide-based perovskite oxide semiconductors for gas sensing applications: a focus on doping effects and development

“…breath, leakage in oil and gas pipelines, petrochemical, power stations, warning of re due to leakage of combustible gases, testing of drunken drivers by traffic police, public safety, in automobiles for exhaust detection, smart sensing in the food industry like testing of the freshness of foods and estimating the time of ripening of fruits, in the electronic industry like smart watches which is having O 2 level sensors, in buildings and smart city applications. [12][13][14][15][16][17][18] According to the market analysis report, the value of the global gas detection market was approximated at USD 2549 million in 2022. The gas detection market is expected to grow by a compound annual growth rate (CAGR) of 7.80% from 2023 to 2032, as reported in Fig.…”

“…Nowadays, the applications of gas sensors can be found in large areas like monitoring air quality, the mining industry, medical facilities for diagnosing diseases like liver cancer which depends on breath, leakage in oil and gas pipelines, petrochemical, power stations, warning of fire due to leakage of combustible gases, testing of drunken drivers by traffic police, public safety, in automobiles for exhaust detection, smart sensing in the food industry like testing of the freshness of foods and estimating the time of ripening of fruits, in the electronic industry like smart watches which is having O 2 level sensors, in buildings and smart city applications. 12–18…”

Optical absorption and photoluminescence properties of Cucurbita maxima dye adsorption on TiO2 nanoparticles

“…Natural dye sensitisers are an attractive area of research because of the abundance, low cost, nontoxicity, and biodegradability of materials. Natural dye extracts from the leaves, roots, tree bark, and flowers have been studied and applied as sensitisers with acceptable levels of efficiency [5][6][7][8][9][10]. However, few experimental studies provide optical absorption and photoluminescence properties on the interaction of dye extracts with wide-band-gap semiconductor materials; therefore, more fundamental studies on natural dye sensitisers are still needed.…”

Effect of different solvents on color extraction and comparative study of their color profile and antioxidant profile of Palash and Jaba flower petals

“…It has been chemically reported that both flower petals are given benefits in anticonvulsive, antidiabetic, anti-inflammatory, hepatoprotective, antihelmintic, antioxidant, antistress, antimicrobial activities, etc. This study evaluated the extraction of one color of dye (yellow) from the Butea Monosperma flower and another dye (red) from the hibiscus flower (Kasture et al, 2002;Mak et al, 2013;Pandit et al, 2016;Rengarajan et al, 2020;Sinha et al, 2012;Yadav et al, 2023). Flower Petals uses the extracted dyes as a source of nontoxic and eco-friendly dye.…”
