Exploring the in Vitro Operating Window of Glycosyltransferase PtUGT1 from Polygonum tinctorium for a Biocatalytic Route to Indigo Dye
<p>The eobiotic compound indican lends itself to a compelling biocatalytic dyeing strategy for denim, in which the formation of corrosive byproducts is avoided. However, the efficient and scalable production of indican remains a key bottleneck. This work focuses on the <em>in vitro</em> characterization of <em>Pt</em>UGT1, a glycosyltransferase from <em>Polygonum tinctorium</em> that catalyzes the formation of indican via the glycosylation of indoxyl. Here, the buffer composition and enzyme concentration were identified as key parameters for enzyme activity and stability. The short lifetime of the enzyme under reaction conditions initiated an immobilization study. As a consequence, an amino-functionalized methacrylate resin was identified as a highly functional option for efficient immobilization of <em>Pt</em>UGT1, allowing immobilization yields of >98% for enzyme loadings up to 7.6 wt %. We further report a stabilization factor of 47 and significantly improved overall biocatalytic productivity. The straightforward handling and reuse of the described heterogeneous biocatalyst is demonstrated.</p>

Data for: Activation of bisulfite by LaFeO3 loaded on red mud for degradation of organic dye
<p>In this study, red mud was used as a support for LaFeO3 to prepare a synergistic catalyst (LaFeO3-RM) via ultrasonic-assisted sol-gel method for the enhanced removal of methylene blue (MB) assisted with bisulfite (BS) in an aqueous solution. The Characterization of SEM and BET indicated that comparing with the non-porous structure of bulk LaFeO3, LaFeO3-RM exhibited high surface area and obvious porous structure with a higher pore volume (i.e. 10 times). XRD, XPS and FTIR revealed that in addition to dispersing LaFeO3 particles, the support of porous RM also increased Fe oxidation activity, oxygen-containing functional groups and chemically adsorbed oxygen (from 44.3% to 90.3%) of LaFeO3-RM which enhanced the catalytic performance in structure and chemical composition. MB was removed through the synergistic effect of adsorption and catalysis with MB molecule was first absorbed on the surface and then degraded. The pseudo-first-order kinetic constant of LaFeO3-RM was 6 times than that of LaFeO3. Fe(III) in LaFeO3-RM played a key role in the activation of BS to produce SO4·- by the redox cycle of Fe(III)/Fe(II). With the application of LaFeO3-RM as a promising low-cost synergistic catalyst for the activation of BS under neutral condition, this work provides a new approach of using porous industrial waste to improve the catalytic performance of LaFeO3.</p>
Exploring the potential of biphenylamine and triphenylamine-based sensitizers for enhanced efficiency more than 8% in dye-sensitized solar cells
<p>Due to the world's rapidly expanding population and industrial sector, which raises the demand for energy, solar cells can address both global energy and environmental needs. With the aim to enhance the dye-sensitized solar cell (DSSC) efficiency, we designed four metal-free BPA and TPA-based dyes (RK2-RK5) by increasing the donor strength (substituting different groups such as biphenylamine (BPA) and triphenylamine (TPA) in the donor side of the dye) based on the reference dye (RK1) as such dye showed improved DSSC's power conversion efficiency. Density functional theory (DFT) was applied at the B3LYP/6-31G** level to calculate the ground-state (S<sub>0</sub>) optimized geometries of (RK1-RK5). Time-dependent DFT (TD-DFT) was utilized to compute the absorption spectra utilizing four functionals (B3LYP, CAM-B3LYP, PBE1PBE and BHandHLYP) in gas phase and solvent such as dichloromethane (DCM) and ethanol. The comprehensive analysis of RK1-RK5 as well as dyes@TiO<sub>2</sub> was performed, and light was shed on the optoelectronic properties. Frontier molecular orbitals' (FMOs') charge density distribution revealed the sensitizers' intramolecular charge transfer (ICT) from the donor to the acceptor moiety. After adsorption charge transfer was noticed from sensitizer to the TiO<sub>2</sub> semiconductor's surface in dyes@TiO<sub>2</sub>. Dyes adsorption on the TiO<sub>2</sub> cluster would be stable, as revealed by the dyes@TiO<sub>2</sub> cluster's negative binding energy. Additionally, it was found that double donor raises the electronic coupling and electron injection constants in RK4 and RK5, indicating that the charge injection in these newly designed dyes would be superior. As a result, the DSSC efficiency in newly designed derivatives has been improved to 8.05% for RK5 by substituting TPA unit at R1 and R2 position in parent compound. These well-established correlations between structure-property relationship, and performance provide profound insight into how improving the donor moiety strength in organic sensitizers affects device performance. It boosted photovoltaic performance through enhanced short-circuit current density, and light-harvesting efficiency. For high-efficiency in DSSCs, it can be a useful rational molecular designing strategy for D-π -A organic sensitizers.</p>
