Transport stress significantly influences the well-being and survival of abalone, yet the underlying metabolic changes and physiological responses associated with this stress remain poorly understood. To gain comprehensive insights into the metabolic changes and physiological responses of abalone (Haliotis rubra) under transport stress, we conducted a targeted LC-MS metabolomics investigation on haemolymph and gill samples collected at different time points, including post-harvesting (pre-transport), post-transport and post-immersion (water holding period) and post-live exporting transport. The results revealed 143 and 141 metabolites that were significantly different among sampling times in haemolymph and gill, respectively. Notably, most of the metabolite differences occurred between the post-transport and post-immersion times, which indicate the strong impacts of transport stress on abalone metabolism. Interestingly, certain metabolites, such as lactic acid, succinic acid, L-hydroxyglutaric acid, uric acid, and myo-inositol, showed time-dependent increases during transport, suggesting their potential as stress biomarkers in abalone. Moreover, abalone that were acclimatized in holding tanks exhibited lesser metabolic changes compared to non-acclimatized, despite both groups being transported with oxygen supply. This highlights the significance of acclimatization and oxygen supply in reducing stress for abalone during transport. Enrichment analysis on abalone samples at 24 h post-transport compared to 96 h post-immersion identified 12 significantly impacted pathways in haemolymph and 34 pathways in gill tissues, indicating a range of metabolic disturbances in transported abalone, such as energy-related pathways, amino acid metabolisms, carbohydrate metabolisms, vitamin metabolisms, oxidative stress, and others. These results offer valuable insights into the physiological responses of abalone to transport stress, guiding improved transport practices to ensure good q

BiFeO3-BaTiO3 (BF-BT) is a promising high temperature lead-free piezoceramics due to their excellent piezoelectric properties with high Curie temperature (TC>500 °C). While the high leakage current density severely restricted its application. In this work, the leakage mechanism relative to the dielectric properties and piezoelectric properties were systematically studied with a special emphasis on gallium (Ga3+) adding effect in 0.7BiFe(1-x)GaxO3-0.3BaTiO3 (BFGax-BT, 0≤x≤0.10) ceramics. A high resistivity (ρ) of 2.73×1012 Ω·cm-1 and low leakage current (J) of 7.78×10-9 A·cm-2 were achieved at x=0.06, which attributes to the low oxygen vacancies (VO ✶✶). The J-E curves reveal different type of conduction process in BFGax-BT ceramics, including Ohmic conduction, space-charge-limited conduction (SCLC) mechanism and interface-limited Schottky emission. The BFGa0.06-BT ceramic exhibits excellent piezoelectric performance: d33=174 pC·N-1, TC=497 °C, kp=29 %. © 2020, CC BY.

A NIR‐II‐absorbing semiconducting polymer served as an excellent photoacoustic (PA) agent, which was constructed via substitution of strong electron‐withdrawing of ester‐groups. Such agent with TICT‐enhanced reorganization energy (Er) and nonradiative decay (kr) exhibits high photothermal conversion efficiency and PA performance, realizing in vivo long‐term monitoring of tumor *** agents have been of vital importance for improving the imaging contrast and reliability against self‐interference from endogenous substances. Herein, we synthesized a series of thiadiazoloquinoxaline (TQ)‐based semiconducting polymers (SPs) with a broad absorption covering from NIR‐I to NIR‐II regions. Among them, the excited s‐BDT‐TQE, a repeating unit of SPs, shows a large dihedral angle and narrow adiabatic energy as well as low radiative decay, attributing to its strongly electron‐deficient ester‐substituted TQ‐segment. In addition, its more vigorous molecular motions trigger a higher reorganization energy that further yields an efficient photoinduced nonradiative decay, which has been carefully examined and understood by theoretical calculation. Thus, BDT‐TQE SP‐cored nanoparticles with twisted intramolecular charge transfer (TICT) feature exhibit a high NIR‐II photothermal conversion efficiency (61.6 %) and preferable PA tracking of in situ hepatic tumor growth for more than 20 days. This study highlights a unique strategy for constructing efficient NIR‐II photoacoustic agents via TICT‐enhanced PNRD effect, advancing their applications for in vivo *** a service to our authors and readers, this journal provides supporting information supplied by the authors.

Hydrological modeling required essential input data such as river bathymetry, discharge, topographic and floodplain elevation values, manning’s n values, and precipitation. In this study, river bathymetry and spatial distribution of precipitation were focused because of challenges in their estimation and associated uncertainties. These input data are also important in accurate flood risk and vulnerability assessment. Previous studies developed several models for their estimation using remote sensing and GIS. However, further improvement is required for their accurate estimation. This study will be helpful in accurate spatio-temporal estimation of these two input data. Furthermore, it was suggested the use of machine learning approaches to handle big data obtained from satellite images for further improvement in the spatio- temporal estimation.

Tannery wastewater was considered as a heavily industrial wastewater with very high amount of wastewater discharged everyday but not well-treating. The tanning wastewater from producing process contains various high strength toxic chemicals which could do the inhibition for biological treatment process leading to low quality effluent. It is required to perform the pre-treatment process by physical–chemical treatment including coagulation and flocculation in order to reduce the content of toxic chemicals before biological treatment. This study focused on investigate on the performance of Poly Ferric Chloride (PFC) as a flocculant for flocculation process in tannery wastewater treatment due to its advantages which could apply in a wide range of industries to help remove materials suspended in water. The application of PFC was conducted in batch test to find the optimum conditions including pH, PFC dose, and rotation speed in term of treating tannery wastewater performance. In addition, a common flocculant polyaluminium chloride (PAC) was chosen to compare with PFC in term of treatment efficiency and cost effective. As the result, with 0.4 ml/l PFC, pH – 10.4 with 100 rpm spins, it reaches its efficient treatment COD process to 93,3%; NH 4 + 90,4% and SO 4 2- 79,2% with could easily promote a potential alternative flocculant with excellent performance but lower cost.

Anthocyanins are naturally occurring compounds that are responsible for a wide variety of colors in many plants, fruits and vegetables. In this study, the extraction of natural anthocyanins from Vietnamese Carissa carandas L. beverage was optimized using response surface methodology (RSM). We applied a Box–Behnken design consisting of three levels and three factors. Examined factors are extraction temperature (ranging from 40 to 60°C), liquid to solid ratio (ranging from 2:1 to 4:1), extraction time (ranging from 30 to 60 min). Using 60% ethanol as solvent for the process, we determined the maximum yields of anthocyanin was 273.786 mg/L. This yield corresponds to extraction conditions of 3:1 (v/w) liquid to solid ratio, temperature of 48.10 °C with a 44.08 min extraction time. The experimental results also fit well with the proposed response model of anthocyanin yield (R2 = 0.9992). Therefore, this study suggested optimization of different extraction methods for the defatted fruit parts. © 2019 Trans tech Publications Ltd, Switzerland.

Excited-state intramolecular proton transfer (ESIPT)-based solid luminescent materials with multiple hydrogen bond acceptors (HBAs) remain unexplored. Herein, we introduced a family of Janus-type ESIPT chromophores featuring distinctive hydrogen bond (H-bond) selectivity between competitive HBAs in a single molecule. Our investigations showed that the central hydroxyl group preferentially forms intramolecular H-bonds with imines in imine-modified 2-hydroxyphenyl benzothiazole (HBT) chromophores but tethers the benzothiazole moiety in hydrazone-modified HBT chromophores. Imine-derived HBTs generally exhibit higher fluorescence efficiency, while hydrazone-derived HBTs show a reduced overlap between the absorption and fluorescence bands. Quantum chemical calculations unveiled the molecular origins of the biased intramolecular H-bonds and their impact on the ESIPT process. This Janus-type ESIPT chromophore skeleton provides new opportunities for the design of solid luminescent materials.
