A series of novel discotic liquid-crystalline donor–acceptor dyads (D-A) adjusted by changing the chain length of diester groups on perylene were synthesized based on triphenylene and perylene units which linked by a flexible linkage of 9-nonyloxy-1-amine. The mesomorphism properties and their self-assembly behaviors were studied by differential scanning calorimetry, polarized optical microscopy, one-dimensional wide-angle X-ray diffraction, small angle X-ray scattering and two-dimensional wide-angle X-ray diffraction. Charge carrier mobilities were measured by Time-of-flight device. These discotic liquid crystalline compounds exhibited highly efficient ambipolar charge-transport properties and the charge carrier mobility can reach the order of 10 −4 cm 2 v −1 s −1 by segregated donor–acceptor columns, providing potential utility of the strategy in organic optoelectronic applications.

The production of hydrogen through seawater electrolysis has recently garnered increasing concern. However, hydrogen evolution reaction (HER) by alkaline seawater electrocatalysis is severely impeded by the slow H 2 O adsorption and H* binding kinetics at industrial current densities . Herein, a face-centered cubic/hexagonal close packed (fcc/hcp) NiRu alloy heterojunction was fabricated on Ni foam (N doped NiRu-inf/NF) by a low-temperature nitrogen plasma activation. Simultaneously, nitrogen atoms are introduced into the alloy to facilitate d-p hybridization. When N doped NiRu-inf/NF is integrated into a dual-electrode cell for urea-assisted seawater electrolysis, it achieves 100 mA cm −2 with an ultra-low voltage of 1.36 V and excellent stability. Density functional theory (DFT) verifies that the robust d-p hybridization among Ni, Ru and N exhibits more energy level matching for H 2 O molecule adsorption at the Ru sites, while simultaneously reducing the interaction between H* and Ni sites in N -doped NiRu-inf.

ABSTRACT A novel boron flotation agent (N-2-hydroxyoctadecyl-N-Methylglucamine, NHO-NMDG) was fabricated using 1,2-epoxyoctadecane and N-methyl-D-glucamine. The obtained collector possesses both collecting and foaming properties and it was characterized by nuclear magnetic resonance, mass spectrometry, Fourier-transform infrared spectroscopy and X-ray photoelectron spectroscopy methods. The flotation performance for boron removal from the salt lake brine has been studied. The flotation experiments indicated a highly effective removal of boron from the salt lake brine. The boron removal rate in the Da Qaidam brine could reach 67.08% by NHO-NMDG. The mechanism analysis shows that the meglumine group in the bifunctional flotation agent can be complexed with boron, and the long-chain alkyl group can attach to the surface of the bubble and enter into the bubble layer, so as to separate boron from the aqueous solution.

To explore the structure-property of donor-acceptor (D-A) type blue emitter, in this contribution, four star-shaped compounds of p -TPA, m -TPA, p -TPA-TPE and m -TPA-TPE using spirotriphenylamine as the donor unit and triazine as the acceptor core were designed and prepared. The tetraphenylethene (TPE) unit was introduced into the D-A molecules to enhance the emission efficiency in solid state. The photophysical properties of all compounds were comparatively studied through experimental and theoretical methods. All these D-A compounds displayed blue emission (443–487 nm) both in solution and neat film. Compared to p -TPA and m -TPA, p -TPA-TPE and m -TPA-TPE possessed clear aggregated-induced emission (AIE) property and higher emission efficiency in the solid state. Both the doped and non-doped organic light-emitting diodes (OLEDs) based on m -TPA and m -TPA-TPE were fabricated by solution-processable approach. The m -TPA-TPE based non-doped device showed a satisfying performance with a high current efficiency of 4.2 cd/A and an external quantum efficiency of 1.8% in the bluish-green region. This research demonstrates that integrating AIE unit into D-A molecule is an effective strategy for design high efficient blue emitter in non-doped OLEDs.

Lenvatinib (LT) is gradually replacing sorafenib as an alternative targeted drug against advanced hepatocellular carcinoma (HCC). However, the anticancer effects of LT are still limited because of its low cytotoxicity, multidrug resistance (MDR), and tumor relapse. Herein, we constructed a smart biophotonic nanoplatform to overcome the barriers preventing high performance. LT and copper sulfide nanocrystals (Cu2−xS NCs) with excellent photothermal properties in the near-infrared-II (NIR-II) zone were co-encapsulated in poly(D,L-lactide-co-glycolide) (PLGA) through nanoprecipitation. Both in vitro and in vivo evaluations demonstrated that Cu2−xS NCs enhanced the anticancer efficacy of LT, without recurrence. In addition, the presence of copper ions could allow glutathione (GHS) to be consumed and oxygen to be produced, likely suppressing the expression of P-glycoprotein (P-gp) and overcoming the issue of MDR relating to LT. More importantly, synergistic chemo-photothermal therapy with LT and Cu2−xS NCs was more effective than any single therapy or theoretical combination. This nanoplatform is promising for advancing future LT-based treatment strategies for HCC therapy.

In this study, we found the inhibitory effect of d -Tryptophan ( d -Trp) on the bacterial growth and spoilage potential of P. fluorescens and S. baltica . The effectiveness of d -Trp in bacterial growth inhibition was highly dependent on environmental NaCl concentrations. The growth/no growth models were developed to clarify the relationship between salt and d -Trp concentrations for optimal growth-inhibitory effect. It showed that higher levels of NaCl (>3.5%) with d -Trp (>15 mM) are required for growth inhibition. The d -Trp treatment combined with NaCl also retarded the psychrotrophic growth and reduced the respiratory active bacteria at low temperature, indicating that the inhibitory effect of d -Trp might be associated with the tolerance to osmotic and cold stress. Furthermore, the treatment d -Trp combined NaCl (artificial seawater) on salmon fillets was investigated. During refrigerated storage, the d -Trp treated salmon fillet either inoculated with S. baltica or P. fluorescen maintained remained a relatively low level of total volatile basic nitrogen (TVBN) (below 30 mg N/100 g during 8-days storage) and delayed increase of low total viable bacteria counts (TVC) with a longer lag phase of 2 days.

With the rapid development of the chemical industry, large amounts of industrial organic pollutants have constituted a huge threat to the ecological environment. The 3-D porous TPU/TiO 2 /PDA composite foam with outstanding oil/water separation and photocatalytic performances was successfully prepared. Its morphology, chemical composition, surface wettability, mechanical properties, oil/water separation, and photocatalytic performances had been systematically studied by SEM, FTIR, XRD, XPS, Raman, XPS, TGA, contact angle instrument, and ultraviolet spectrophotometer. The results showed that TPU/TiO 2 /PDA composite foam can remove water and oil for various oil/water mixtures and emulsion with outstanding separation performance only under the gravitational force. The water and oil separation flux can reach 21,035 L/m 2 ·h and 14,500 L/m 2 ·h, respectively. The highest separation efficiency reach to 99.6% for petroleum ether/water. It also can continuously separate the oil and water from various water/oil mixtures with the assistance of the pump; after 10 cycles, it maintains large separation efficiency of 98.5%. Moreover, the RhB removal rate reached up to 96% only after irradiation 1 h under UV light. These results manifested that the prepared multifunctional TPU/TiO 2 /PDA composite foams have great application prospect in oil/water separation fields, providing a new idea for fabricating 3-D porous composite foams with multifunctionality. A novel type of 3-D porous TPU/TiO 2 /PDA composite foam with multifunctional applications was successfully designed and prepared. It exhibits excellent performance for oil/water separation and photocatalytic degradation of organic dye. Graphical abstract

Carbonyl reductases (CRs) are promising biological macromolecules for the asymmetric synthesis of chiral secondary alcohols. A novel CR was evolved for efficient conversion of d -xylose into anti-aging ( S )-Pro-Xylane. Through extensive gene mining, an active carbonyl reductase Zm CR was identified from Zygofabospora marxiana with high reductive activity towards d -xylose-derived 1-C-(β- d -xylopyranosyl)-acetone (XPSA) and in situ cofactor regeneration capability. Using a three-round of concise engineering strategy, a hextuple mutant C85V/V128C/S129A/V161S/Y166H/T217A (M6) was identified from merely 157 mutants with specific activity of 46.00 U·mg −1 , about 306 folds of WT. The Shannon-Wiener index of M6 was 2.21, much higher than WT, indicating its extended substrate scope. M6 could efficiently catalyze the asymmetric reduction of 190 g·L −1 XPSA into ( S )-XPSP. The k cat / K M XPSA of M6 was 203.84 s −1 ·mM −1 , about 910 folds of WT. More non-bonded interactions were monitored in M6, contributing to the stabilization of reactive catalytic conformation. This study provides a promising biocatalyst for the chemoenzymatic synthesis of value-added anti-aging ( S )-Pro-Xylane from lignocellulosic d -xylose.

Background/Objectives: Chronic alcohol overconsumption triggers alcohol liver injury, and therapeutic strategies targeting alcohol-triggered oxidative stress and hepatic inflammatory responses represent potential approaches to ameliorating alcohol-related hepatotoxicity. This study aimed to determine the hepatoprotective activity of finger citron essential oil (FCEO) in alcoholic liver disease (ALD)-afflicted rats and explore its underlying mechanisms. In order to identify the effective components, we compared the effects of FCEO and D-limonene.Methods: The regulatory effects of FCEO on metabolic enzymes were systematically evaluated through in vitro experiments. In vivo studies were conducted to investigate and compare the hepatoprotective effects of FCEO and D-limonene. Staining methods, assay kits, and Western Blot were used to determine the roles of FCEO and D-limonene in the ALD rats.Results: We found that FCEO downregulated phase I metabolic enzymes and upregulated phase II metabolic enzymes in Buffalo Rat Liver-3A (BRL-3A) cells. FCEO and/or D-limonene intervention reduced transaminase levels in ALD rats and effectively alleviated inflammatory cell infiltration and lipid droplet accumulation in their liver tissue. Additionally, FCEO and D-limonene played a regulatory role in oxidative stress and inflammation-related pathways such as the MAPK/Nrf2 and NF-κB/AMPK pathways. FCEO was superior to D-limonene as an antioxidant in alleviating alcoholic liver injury.Conclusions: This study revealed the alleviative effects and mechanisms of FCEO on alcoholic liver injury, demonstrating better efficacy compared to its monomer, thus providing a strategy for the development and utilization of finger citron resources.

Donor-Acceptor (D-A) copolymers are critical for cost-effective and energy-efficient electrochromic devices (ECDs) and smart windows. In this study, a type of copolymers with dual-introduction of alkyl thiophene as π spacer and fluorine are designed for highly efficient ECDs, contributing to superior color efficiency (CE). Through π spacer modification, the twist angle as well as the optical bandgap of the copolymers (PDT-Th-BT) are minimized via blocking the F…O noncovalent repulsive interaction. ECDs based on PDT-Th-BT1F are achieved with high CE of 1440 cm²/C, along with electrochromic contrast up to 41.6%. This CE is the best yet among ECDs based on fluorination D-A type copolymers according to literature. Furthermore, smart window made from PDT-Th-BT1F contribute a 5 ℃ cooling down compared to the glass in the building models and an energy saving of 631,257.14 kWh in a 26,404.54 m 2 building model, greatly conducive to environmental protection. This work presents a viable strategy for the development of highly efficient ECDs and smart windows.

Four new d-block metal complexes formulated as [NiII(H3thptacn)]Cl2·H2O (1), [MnIV(thptacn)]ClO4 (2), [CuII3(Hthptacn)2](ClO4)2 (3), and [CdII2(H3thptacn)2Cl2][B(C6H5)4]2 (4) were obtained from the macrocyclic ligand 1,4,7-tris(3-hydroxypropyl)-1,4,7-triazacyclononane (H3thptacn) either through solvent diffusion or by evaporation of their solutions. These complexes were characterized by single crystal X-ray structural determination, elemental analysis, and routine spectroscopic methods. Complexes 1 and 2 exhibit similar mononuclear structures with the metal centers being surrounded by both the backbone nitrogen atoms and the pendant coordinating alcohol/alkoxide groups. Complex 3 is a linear trinuclear cluster, where three Cu(II) centers are combined together by the bridging alkoxide groups in a centro-symmetric pattern. Two chloride groups join two Cd(II) atoms each chelated by one triply protonated ligand H3thptacn to afford dinuclear compound 4 with a symmetry center. When coordinating to different d-block metals, the macrocyclic ligand exhibits four types of binding modes with various dissociation status on its pendant alcohol groups and different numbers of these pendant groups participating in coordination. The magnetic measurements revealed significant zero-field splitting for mononuclear Ni(II) and Mn(IV) complexes. A moderate antiferromagnetic interaction between the neighboring Cu(II) centers governs the magnetic properties of 3 with J = −166(3) cm−1.

Reduction of inflammation and thrombosis caused by implanted devices is critical for clinical success. To this end, the strategy based on programmable release of anti-inflammatory and anti-thrombotic agents from the widely-used polycaprolactone (PCL)/gelatin nanofiber scaffold is developed. The release of 2-O- d -Glucopyranosyl- l -ascorbic Acid (AA-2G) and heparin are controlled by reactive oxygen species (ROS)-responsive poly(ethylene glycol)-based β-thioether ester copolymer (PEGDA-EDT) and mesoporous silica nanoparticles (MSN) in the nanofiber, respectively. The in vitro assay demonstrate that the scaffolds are hemocompatible with the resistance of platelet adhesion; the control release of AA-2G prevents initial inflammation and oxidation of the blood cells, and the subsequent release of heparin entitles nanofibers with long-term anti-thrombotic capability. In addition, rapid endothelialization is obtained on the surface of nanofiber scaffolds for the further enhancement of the hemocompatibility. In vivo implant evaluation convinces that the nanofiber scaffolds possess high biocompatibility with the substantial resistance for inflammation and thrombosis. Hence, our work paves a new way to develop the anti-inflammatory and anti-thrombotic tissue-engineering substrates through programmable delivery of two or multiple drugs.
