Article Abstract
The absorption, fluorescence and time-resolved fluorescence spectra of Rhodamine 101 dye in both methanol and acidic methanol solutions were measured. The authors achieved the characteristic information of the absorption and fluorescence spectra, and obtained the S1 lifetimes. The authors assigned vibrational modes of the Rhodanmine 101 dye molecule through spontaneous Raman spectrum, infrared spectrum, and density function theory calculation. This work systemically characterizes the spectral, molecular structural, and vibrational information of Rhodamine 101 dye molecule, and provides necessary information for the application of Rhodamine 101 dye in dye sensitized solar cell and biological fluorescence marker.

Lipases are one of the ubiquitous enzymes that belong to the hydrolases family and have a wide variety of applications. Cold-active lipases are of major attraction as they can act in lower temperatures and low water conditions because of their inherent greater flexibility. One of the novel applications of lipase is the enrichment of ω-3 polyunsaturated fatty acids (PUFA) in plant and fish oils.

To efficiently treat rhodamine B (RhB) and tetracycline (TC) in wastewater, MIL-101(Cr) was prepared by hydrothermal method and encapsulated with phosphotungstic acid (HPWO, abbreviated as PTA) to form an S-scheme heterojunction PTA@MIL-101(Cr)-x (P@M-x, x = 50, 100, 150, 200). The experimental results showed that after 180 min under visible light at pH 7, the degradation rates of RhB and TC were 97.81% and 99.

Unlabelled: The heterogeneous sonocatalysis is considered as an impressive remediation approach to eliminate the dyeing wastewaters. Among the efficient sonocatalytic remediation, nanocomposite sonocatalysts have grabbed special attention in recent years. In the presence research, the novel MIL-101(Fe)/ZrO/MnFeO nanocomposite as a magnetically retrievable catalyst was elaborated using the ultrasound-assisted hydrothermal route and its sonocatalytic performance was tested applying the methylene blue (MB), rhodamine B (RhB), congo red (CR), and methyl orange (MO) organic dyes under US/HO system.

The natural process of photosynthesis involves a series of consecutive energy transfers, but achieving more steps of efficient energy transfer and photocatalytic organic conversion in artificial light-harvesting systems (ALHSs) continues to pose a significant challenge. In the present investigation, a range of ALHSs showcasing a sophisticated three-step energy transfer mechanism is designed, which are meticulously crafted using pillar[5]arene (WP[5]) and p-phenylenevinylene derivative (PPTPy), utilizing host-guest interactions as energy donors. Three distinct types of fluorescent dyes, namely Rhodamine B (RhB), Sulforhodamine 101 (SR101), and Cyanine 5 (Cy5), are employed as acceptors of energy.

The interplay on anatase TiO photoactivity between particle morphology and gold nanoparticles (NPs) deposition, via either deposition-precipitation (DP) or photodeposition (P), is here investigated by evaluating the photoactivity of Au modified anatase (Au/TiO) nanocrystals with either a pseudospherical shape or a nanosheet structure in both reduction and oxidation test reactions. The presence of Au NPs on the anatase surface only slightly affects its photoactivity in Cr(VI) reduction, which is kinetically limited by the anodic half-reaction, whereas a larger exposure of highly oxidant {001} facets is beneficial for overcoming this rate-determining step. In the photocatalytic oxidation of both formic acid, proceeding through a direct mechanism, and rhodamine B (RhB) on surface fluorinated photocatalysts, occurring through a hydroxyl-radical-mediated mechanism, the presence of gold NPs produces a significant photoactivity increase only with spherically shaped photocatalysts, mainly exposing {101} facets.
