Herein, we have reported the highly effective use of the Knoevenagel condensation reaction to synthesize organoselenium containing quinoline-based probe. The probe was characterized by Nuclear Magnetic Resonance and Infra-Red spectroscopy and mass spectrometry. The probe selectively detects KO2 with high sensitivity over other reactive oxygen species and biothiols. Photo-induced electron transfer process is responsible for fluorescence “turn-on” event through transformation of selenide to selenoxide. The probe reacted with KO2 in less than a second with lower detection limit (0.14μM). The probe have better anticancer potency as compared to standard drug Cisplatin.

A schematic strategy is presented to overcome the problem of low photocatalytic performance of graphene. Herein, we synthesized nitrogen-doped graphene (NDG)-coupled acid fuchsin (AF) photocatalyst, i.e.; NDGCAF photocatalyst. The NDGCAF photocatalyst has excellent solar light harvesting ability, band gap suitability, and high molar extinction coefficient than the NDG photocatalyst. Due to these properties, the NDGCAF photocatalyst has the ability to oxidize aryl-vinyl into aryl-vinyl-aldehyde under the irradiation of visible light. In this context, it exhibited the utmost conversion efficiency of aryl-vinyl to aryl-vinyl-aldehyde with a good yield of 98.15% . Current research highlights the significant application of NDGCAF light-harvesting photocatalysts in the research field of organic transformations.

In recent years, the photocatalytic properties of TiO2 have been extensively studied. The anatase crystal structure of TiO2 has a high reduction power and high photocatalytic activity. In present study, boric acid-based titanium dioxide and non-doped titanium dioxide have been produced by the two different methods and different sintering temperatures. Structural analysis indicated that boron-based samples resulted in spread homogeneously as in anatase crystal structure. Samples compared in different parameters were subjected to X-ray diffraction, Scanning Electron Microscope, Fourier-transform infrared spectroscopy, and moisture holding capacity measurements. XRD analysis of TiO2 samples produced at 450°C, 600°C, and 750°C sintering temperatures was carried out to determine and compare crystal structures. The boron additive has been shown to maintain anatase crystal structure at high temperatures. The highest XRD score of anatase phase values were achieved as 73 and 78 at 750°C. These results were observed in boron-based samples. When the moisture holding capacity was examined, boric acid contribution has been seen to increase this capacity. The results demonstrated that these boron-based titanium dioxides with maintain anatase crystal structure in high temperatures, and promise moisture-holding capacity are prominent candidates for smart materials.
近年来，人们对二氧化钛的光催化性能进行了广泛研究。锐钛型晶体结构的二氧化钛具有很强的还原力和很高的光催化活性。本研究采用两种不同的方法和不同的烧结温度制备了硼酸基二氧化钛和非掺杂二氧化钛。结构分析表明，硼基样品形成了均匀的锐钛矿晶体结构。对不同参数的样品进行了 X 射线衍射、扫描电子显微镜、傅立叶变换红外光谱和保湿能力测量。对 450°C、600°C 和 750°C 烧结温度下生产的 TiO2 样品进行了 X 射线衍射分析，以确定和比较晶体结构。结果表明，硼添加剂能在高温下保持锐钛矿晶体结构。在 750°C 时，锐钛矿相的最高 XRD 值分别为 73 和 78。这些结果是在硼基样品中观察到的。在检查保湿能力时，发现硼酸的加入提高了保湿能力。结果表明，这些硼基二氧化钛能在高温下保持锐钛矿晶体结构，并具有良好的保湿能力，是智能材料的理想候选材料。

A novel, highly efficient, eco-friendly, and quick microwave-assisted synthesis of 2, 4, 5- substituted imidazoles by one-pot cyclo condensation of acenaphthoquinone, aromatic aldehydes, and ammonium acetate was reported under solvent-free conditions using ammonium chloride as a catalyst with excellent yield. The present methodology offers several advantages, such as mild reaction conditions, easy workup, short reaction time, excellent yield, purification of products by the non-chromatographic method, and reproducibility in large-scale synthesis. Compounds were characterized by IR, 1HNMR, 13C NMR spectroscopy and their melting points were compared with the literature reports.
