Dermanyssus gallinae is a significant haematophagous ectoparasite of laying hens. Despite the worldwide application of beta-cypermethrin for mite control, resistance to this compound has been developed by D. gallinae . P450s, as key detoxification enzymes involved in the metabolism of exogenous and endogenous chemical substances, have not been functionally characterized in D. gallinae . Here, the role of the P450s gene (Deg-CYP-3) of D. gallinae in acaricide resistance was studied. Firstly, P450s activities of the five beta-cypermethrin resistant strains (RR) against p-nitroanisole were significantly higher than that of the susceptible strain (RS), suggesting enhanced enzymatic activities might contribute to mite beta-cypermethrin resistance. Both mRNA expression level and DNA copy number of Deg-CYP-3 were significantly higher in RR than in RS, except for DK RR strain. Moreover, recombinant Deg-CYP-3 (rCYP-3) expressed in Escherichia coli displayed high enzymatic activity against p-nitroanisole, while Qulaton-100, acetone, isoacetone, avermectin, and ivermectin were found to inhibit this activity. Immunohistochemical analysis revealed the presence of Deg-CYP-3 protein in the digestive tract and Malpighian tubules. Finally, silencing of Deg-CYP-3 via RNAi resulted in decreased enzyme activity and increased susceptibility of PG RR strain to beta-cypermethrin, confirming that Deg-CYP-3 is crucial for beta-cypermethrin detoxification. RNAi also resulted in enhanced mortality, as well as reduced oviposition and fecundity in the PG RR strain. Collectively, these findings indicate that resistance of D. gallinae to beta-cypermethrin is associated with elevated P450s protein activity and increased Deg-CYP-3 expression levels. The results provide insights into the metabolic resistance mechanisms of D. gallinae and offer scientific guidance for the management and control of mite.

Immunoregulation is an emerging treatment strategy to promote wound healing by modulating the local immune system at the wound site. In this study, an extracellular matrix biomimetic and polysaccharide-based hydrogel was engineered to regulate the wound immune environment through Michael-type addition between maleimidyl pullulan and chitosan modified with hydroxyproline. The proposed hydrogel exhibited favorable injectable and self-healing properties, which facilitated the full coverage of irregularly shaped wounds. A natural polyphenol, epigallocatechin-3-gallate (EGCG), was incorporated into hydrogels, which thereby exhibited excellent biocompatibility, good reactive oxygen species (ROS) scavenging ability, anti-inflammatory activity, and antibacterial properties against S. aureus and E. coli . Furthermore, evaluations of a full-thickness skin defect mice model showed that the hydrogel with EGCG effectively alleviated the inflammatory response by reducing pro-inflammatory cellular infiltration and down-regulating the inflammatory cytokine TNF-α, while up-regulating anti-inflammatory cytokine IL-10. Notably, a faster wound healing rate was also achieved by the better promotion effect of the hydrogel on increasing the formation of re-epithelialization, granulation tissue generation, collagen deposition, and angiogenesis. Therefore, our immunoregulatory strategy showed great potential in the design of biomaterials for wound management.

The vapor transport deposition of quasi-one-dimensional antimony selenosulfide (Sb 2 (S,Se) 3 ) has recently attracted increasing research interest for the inexpensive, high-throughput production of thin film photovoltaic devices. Further improvements in Sb 2 (S,Se) 3 solar cell performance urgently require the identification of processing strategies to control the orientation, however the growth mechanism of high quality absorbers is still not completely clear. Herein, a facile and general vapor transport deposition approach to precisely control the growth of large-grained dense Sb 2 (S,Se) 3 films with good crystallization and preferred orientation via the source vapor speed is utilized. It is found that defect activation energy rather than the defect concentration plays a decisive role in the Sb 2 (S,Se) 3 photovoltaic performance. Admittance spectroscopy analysis is used to obtain efficient Sb 2 (S,Se) 3 solar cells. By employing dual-source coordinations to optimize the absorber layer a power conversion efficiency of 8.17% is obtained which is the highest efficiency for Sb 2 (S,Se) 3 solar cells fabricated by vapor transport technology. This study suggests that there are other opportunities for gaining deeper a understanding of the defect physics and carrier recombination mechanisms in other highly oriented low-dimensional materials to achieve improved device performance.

Na superionic conductors (NASICONs) have attracted much attention due to their unique framework structure and high capacity. However, the poor intrinsic electron conductivity severely limits further development. This work develops a soft-hard carbon composite modified Na3V2(PO4)3 (NVP) cathode with excellent rate performance and long-term cycling stability. The optimized sample exhibits excellent electrochemical performance and can release a specific discharge capacity of 102.7 mAh g-1 at 1 C rate. At the same time, after 5000 cycles at 20 C rate, the discharge capacity can reach 82.3 mAh g-1, and the capacity retention rate is 100.1 %. The morphological characteristics of the NVP/C samples were investigated, Meanwhile, combined with Raman spectroscopy and electrochemical analysis, these results revealed that the synergistic interaction between soft and hard carbon components significantly enhances electronic conductivity and facilitates rapid ionic transport. This work provides a unique idea for the surface modification and synthesis of NASICON cathode materials for sodium-ion batteries.

The oxygen balance (OB) of energetic materials plays a critical role in determining the efficiency and effectiveness of energy release during combustion or detonation. To enhance the OB and comprehensive properties of 3-picrylamino-1,2,4-triazole (PATO), which is a high-energy and low-sensitivity explosive, this study employed a self-assembly strategy to combine nitric acid with PATO, resulting in a novel 3-picrylamino-1,2,4-triazole-nitric acid self-assembled energetic material (PATO-N). Its structure was characterized by single crystal X-ray diffraction, and the thermal decomposition properties and impact sensitivity were measured. The detonation performances were predicted by EXPLO5 and the OB was calculated based on its molecular formula. The results indicate that the self-assembly of PATO and HNO3 effectively enhanced the explosive's OB (−67.7% to −44.6%)and promoted the completeness of the detonation reaction. PATO-N exhibits good thermal stability with an improved decomposition temperature of 315.9 °C. Its theoretical detonation velocity is 7.8 km s−1, while the detonation pressure is 25.2 Gpa. PATO-N exhibited an impact sensitivity (H50) exceeding 112.2 cm, classifying it as an insensitive energetic material.

This work utilized Y 2 O 3 and rGO as additives, and systematically regulated their spatial distribution and composite ratio with Na 3 V 2 (PO 4 ) 3 (NVP) to overcome the bottlenecks faced by NVP, such as intrinsically low electronic conductivity, severe interfacial side reactions, and structural instability during cycling. The modified NVP cathode can significantly enhance its electrochemical performance, and improve its sodium storage and thermal safety performance in the pouch-type full cell. The as-prepared NVP@Y 2 O 3 @rGO material achieves an 84 % capacity retention rate after 1000 cycles at 1C&27 °C, while still delivering a specific capacity of 49.6 mAh g −1 at an ultra-high rate of 30C. Under elevated temperature of 45 °C, it maintains 91.5 % capacity retention after 400 cycles at 1C. In contrast, the pristine NVP retains only 38.2 %. Moreover, it exhibits a reversible capacity of 63.6 mAh g −1 even at an ultra-high rate of 40C. More importantly, pouch-type full cell testing further confirms its superior cycling stability (60.8 % capacity retention after 100 cycles, representing a 30.5 % improvement over the unmodified sample). Mechanistic studies reveal that the combined effects of Y 2 O 3 and rGO effectively facilitate electron/ion transport, suppress electrode-electrolyte interfacial side reactions, mitigate volume change stress, and enhance structural integrity. This work offers new insights for designing high-stability cathode materials for sodium-ion batteries.

Lanthanide-doped Ca 3 Ln(AlO) 3 (BO 3 ) 4 phosphors are adopted for numerous new types of applications with outstanding optical properties. Herein, the novel Ca 3 Gd(AlO) 3 (BO 3 ) 4 :Dy 3+ phosphors were synthesized by the high-temperature solid-state method. X-ray diffraction, scanning electron microscopy, transmission electron microscopy, diffuse reflection spectroscopy, and as well as photoluminescence (PL) spectra and lifetime curves are used to exemplify the resulting samples. This research explores the samples microstructure and the influence of Dy 3+ doping at the Ca and Gd sites. The PL spectrum results indicated that Ca 3 Gd(AlO) 3 (BO 3 ) 4 :Dy 3+ can be effectively excited by 349 nm UV light and emits bright white light results of Dy 3+ ions with the 4f–4f transition. The optimum doping content of the Dy 3+ in the Ca 3 Gd(AlO) 3 (BO 3 ) 4 host samples were 7 mol%, and the concentration quenching (CQ) mechanism was mainly owing to dipole–dipole interaction. Interestingly, the Ca 3 Gd 0.93 (AlO) 3 (BO 3 ) 4 :0.07Dy 3+ showed exceptional thermal-quenching resistance of > 87.3% intensity at 350 K. The temperature-sensing properties of Ca 3 Gd 0.93 (AlO) 3 (BO 3 ) 4 :0.07Dy 3+ ranging from 300 to 500 K were analyzed and had shown a decent maximum S A value about 1.35% K −1 at 500 K between 455 and 669 nm fluorescence intensity ratio. Hence, the novel Ca 3 Gd 0.93 (AlO) 3 (BO 3 ) 4 :0.07Dy 3+ materials could be a competent candidate for low-cost and non-contact optical thermometry in a high-temperature environment.

The precursors used to prepare high-quality nanoparticles by high-temperature decomposition are expensive and toxic organometallic compounds. Fe(OH)3, an inexpensive and environmentally friendly iron-containing compound, is for the first time introduced to act as an precursor to generate monodisperse iron oxide nanoparticles. The obtained nanoparticles are characterised by transmission electronic microscopy, IR, XRD and vibrating sample magnetometer. Organic-soluble ferromagnetic rod-like and superparamagnetic dot-like nanoparticles with the size ranging from 12 to 25 nm are obtained in a nonpolar solvent by adjusting reaction parameters, such as surfactant concentration and reaction time. Water-soluble nanoparticles can be synthesised when a bipolar solvent is used instead of nonpolar solvent. The results show that Fe(OH)3 is a promising precursor for the high-temperature decomposition method.

Aqueous zinc batteries have been regarded as a promising energy storage technology due to their high energy, high material abundance, low toxicity, and intrinsic safety. NASICON-type materials have been proposed as efficient cathodes for rechargeable batteries, yet they suffer from fast degradation and low Coulombic efficiency in aqueous batteries. Here we demonstrate that a rationally designed aqueous electrolyte containing a supporting Na salt and polymer additive can efficiently suppress the water activity through hydrogen bonding and facilitate the anion involvement in interfacial reactions, thus enabling the stable operation of sodium superionic conductor (NASICON) cathodes in aqueous zinc batteries. As exemplified by a Na 3 V 2 (PO 4 ) 3 cathode, the cell with zinc metal anode exhibits high cycling Coulombic efficiencies (around 99.9 % in average) with a steady output voltage and capacity retention for 300 cycles. This work addresses the potential issues with NASICON-type cathodes in aqueous zinc batteries and proposes an effective solution via fundamental interphasial chemistry to design efficient and sustainable aqueous electrolytes. Graphical Engineering electrode-electrolyte interphase : A rationally designed aqueous electrolyte with bi-cation and polymer additive is reported for aqueous zinc batteries with NASICON cathodes. As exemplified by a Na 3 V 2 (PO 4 ) 3 cathode, the full cells exhibited remarkable cycling stability and efficiency, benefiting from the well-suppressed material dissolution by electrolyte-induced interfacial engineering.

Because of its tunable band gap and band position, Sb 2 (Se 1 − x S x ) 3 (0 ≤ x ≤ 1) is a promising light-absorbing material for photovoltaic device applications. However, no systematic study on the synthesis and characterization of single-phase polycrystalline Sb 2 (Se 1 − x S x ) 3 thin films has been reported. Through introducing in situ sulfurization into the rapid thermal evaporation process, a series of single-phase, highly crystalline Sb 2 (Se 1 − x S x ) 3 films with x = 0.09, 0.20, 0.31, and 0.43 were successfully obtained, with the corresponding band gap, band position and film morphology fully revealed. Futhermore, solar cells with superstrate ITO/CdS/Sb 2 (Se 1 − x S x ) 3 /Au structure were fabricated and carefully optimized. Finally, a champion device having 5.79% solar conversion efficiency was obtained employing uniform Sb 2 (Se 0.80 S 0.20 ) 3 absorber layer. Our experimental investigation confirmed that Sb 2 (Se 1 − x S x ) 3 is indeed a very promising absorber material worth further optimization. Copyright © 2016 John Wiley & Sons, Ltd.

Inferior rate capability is a big challenge for LiTi 2 (PO 4 ) 3 anode for aqueous lithium-ion batteries. Herein, to address such issue, we synthesized a high-performance LiTi 2 (PO 4 ) 3 /carbon/carbon nanotube (LTP/C/CNT) composite by virtue of high-quality carbon coating and incorporation of good conductive network. The as-prepared LTP/C/CNT composite exhibits excellent rate performance with discharge capacity of 80.1 and 59.1 mAh g −1 at 10 C and 20 C (based on the mass of anode, 1 C = 150 mA g −1 ), much larger than that of the LTP/C composite (53.4 mAh g −1 at 10 C, and 31.7 mAh g −1 at 20 C). LTP/C/CNT also demonstrates outstanding cycling stability with capacity retention of 83.3 % after 1000 cycles at 5 C, superior to LTP/C without incorporation of CNTs (60.1 %). As verified, the excellent electrochemical performance of the LTP/C/CNT composite is attributed to the enhanced electrical conductivity, rapid charge transfer, and Li-ion diffusion because of the incorporation of CNTs.
