Estrogen therapy offsets thermal impairment of vitellogenesis, but not zonagenesis, in maiden spawning female Atlantic salmon (Salmo salar)
Authors: Anderson Kelli , Pankhurst Ned , King Harry , Elizur Abigail 
Published: November 2017

In female Atlantic salmon (Salmo salar), exposure to warm summer temperatures causes a reduction in plasma 17β-estradiol (E2), which impairs downstream vitellogenesis and zonagenesis, and reduces egg fertility and embryo survival. The aim of the present study was to determine whether E2-treatment could offset thermal impairment of endocrine function and maintain egg quality in maiden (first-time-spawning)S. salarreared at 22 °C. Treatment with E2 at 22 °C stimulated vitellogenin (vtg) gene expression and subsequent protein synthesis which promoted oocyte growth and increased egg size relative to untreated fish at 14 and 22 °C. However, E2-treatment at 22 °C was not associated with an increase in egg fertility and embryo survival relative to untreated fish at 22 °C, despite the positive effects of E2-treatment on vitellogenesis and oocyte growth. As there was no evidence to suggest that the estrogen receptor alpha expression was suppressed by high temperature, this could be due to the lack of stimulation on zonagenesis by E2-treatment observed at high temperature during oocyte development. Our results demonstrate that treatment with E2 is not able to maintain zonagenesis or egg quality in maidenS. salarat high temperature, even whenvtggene expression, protein synthesis and subsequent oocyte growth is promoted. This implies that the mechanisms regulating zonagenesis, but not vitellogenesis are impaired at elevated temperature in femaleS. salarbroodstock, and highlights the remarkable complexity of thermally induced endocrine disruption in fish.

AbstractPrevious research has established a connection between parental control and bullying. However, the nuanced relationships involving different combinations of psychological control (PPC) and behavioral control (PBC), along with traditional and cyberbullying, remain ambiguous. Thus, this study investigated the associations of specific parental control dimensions and profiles with traditional and cyberbullying, focusing on the potential mediating mechanism of moral disengagement. A sample of 831 students (48.4% were female; Mage = 18.98 years; SDage = 1.08) was analyzed. Through latent profile analysis, three control profiles emerged: low PPC and PBC (40.31%), low PPC and high PBC (29.00%), and high PPC and PBC (30.69%). The findings indicated a positive correlation between PPC and traditional/cyberbullying. Moral disengagement mediated the relationship between PPC/PBC and traditional/cyberbullying. Particularly, high PPC and PBC were linked to cyberbullying. Moral disengagement mediated the relationship between high PPC and PBC and traditional/cyberbullying. These insights provide valuable empirical data for developing bullying interventions that consider parental control and moral disengagement.

AbstractPotassium‐ion batteries (PIBs) are emerging as powerful candidate for grid‐oriented energy storage owing to their potentially low cost. Carbon is considered the promising anode for PIBs on the basis of its high conductivity and abundant sources. The biggest challenge confronted by carbon anodes lies in insufficient cycle life as well as rate capability, resulting from the limited interlayer spacing of the sp2‐hybrid carbon incompatible with the large‐radius potassium. Herein, a biomass‐derived carbon with a large interlayer spacing of 0.44 nm is fabricated via a zinc‐assisted pyrolysis synthesis. The unique structure endows the carbon with superior capacity, rate capability, and cycle durability. The large interlayer spacing of carbons can promote fast potassium diffusion and alleviate the volume expansion during potassiation, conferring those rate capabilities and cycleability. The interconnected network structure is also able to shorten both the transport distances of electrons and ions. The demonstration exemplifies an advanced carbon for anodes of PIBs for energy storage applications.

AbstractBiological and mechanical mismatches between engineered scaffolds and native tissues poses widespread challenges for tissue restoration. Native‐like anisotropy is a critical characteristic for functional tissue replacements, yet it is an often‐overlooked aspect when designing new scaffolds. In this study, fiber‐reinforced tubular scaffolds are developed, mimicking the anisotropic characteristics of natural tissues, using native‐like silk fibroin. To predict the mechanical behavior of these innovative scaffolds, a mathematical model is employed, utilizing the properties of the scaffolds’ constituent materials, and experimentally validated through tensile testing. This approach addresses significant challenges in the design of new scaffold implants by enabling to efficiently predict the performance of several configurations, narrowing down the experimental research space. The proposed platform constitutes an appealing tool for the development of clinically relevant tissue‐equivalents.

Published: October 2024

AbstractA novel spoof surface plasmon polaritons (SSPP) structure is applied to the design of radio frequency (RF) power amplifiers (PAs) in this work. Both standard SSPP and the proposed SSPP structures are used as input and output matching networks of a multioctave PA design. An analysis and discussion of the electromagnetic characteristics of the proposed SSPP structures is presented. Further optimization of PA performance is achieved by utilizing the gradient algorithm of the Advanced Design System tool. According to the test results, the newly developed SSPP‐based PA achieves output power ranging from 40.5 to 42.6 dBm, while the power additional efficiency varies between 60% and 66.55%, with a total layout size of 59.8 mm × 14.6 mm in the frequency band of 0.8–3.2 GHz. In comparison with recent published work, the PA designed in this work expands the bandwidth while maintaining high output power and efficiency while being smaller in size.

AbstractMolecular emitters that combined thermally activated delayed and circularly polarized fluorescence (CP‐TADF) is of paramount importance for the next generation of displays. While most efforts have thus far focused on covalent donor and acceptor CP‐TADF emitters, a novel strategy based on chiral exciplexes has recently emerged. In this context, we present the synthesis and chiroptical properties of four new CP‐TADF exciplexes, involving two distinct C2‐symmetric bicarbazole systems and two terpyridine‐based derivatives, which serve as the chiral donor and achiral acceptor units, respectively. These exciplexes exhibit CP‐luminescence, with intensity dependent on both the chiral donor and achiral constituents, resulting in emission dissymmetry factors reaching up to 10⁻2 in the thin‐film solid state. Additionally, small singlet‐triplet gaps (∆EST ≤ 0.1 eV) have been measured, leading to TADF characteristics with a photoluminescence quantum yield of 20% for the most efficient emitter, which is also successfully used in non‐optimized organic lightemitting diodes (OLEDs). Interestingly, these chiral exciplexes allow us to explore the impact of the locally‐excited (LE) state of the chiral donor on overall exciplex emission, particularly in relation to the intensity of polarized emission—potentially highlighting a key factor in the design of this type of bimolecular CP‐TADF emitter.

AbstractFar‐red phosphor‐converted light‐emitting diodes are receiving increasing attention as an essential component of the next‐generation plant‐growth lights. However, developing far‐red phosphors with high quantum efficiency, low thermal quenching, and suitable emitting wavelength is crucial and urgent. Herein, a new far‐red phosphor BaY2Ga3.9GeO12:0.1Cr3+ with high internal quantum efficiency (98%) and thermal stability (90.2%@423K) is obtained via the substitution of CaO8 with bigger BaO8 dodecahedrons, which is attributed to variations in the lattice environment of Cr3+. Meanwhile, controllable emission tuning from 780 to 708 nm and enhanced luminescence performance are achieved due to the cation substitution can reduce the production of Cr4+ and modulate the lattice occupancy of the Cr3+ ions, and the enhancement of metal‐ligand interactions resulting in the enhancement of the crystal field and the breaking of the forbidden d‐d transition of Cr3+. The proof‐of‐concept demonstration of the pakchoi lighting experiment reveals the great potential of BaY2Ga3.9GeO12:Cr3+ phosphor in stimulating plant growth and pushing the yield. These results demonstrate the feasibility of cationic substitution to optimize the optical performance of Cr3+‐doped phosphors, providing an alternative strategy for designing efficient far‐red light sources for plant lighting.

Biomass is an abundant resource, and bioactive compounds produced from biomass are environmentally benign in contrast to conventional chemical synthesis methods, which frequently depend on non‐renewable resources. In addition, the functionalized monomers from biomass allow the atom economical synthesis of bioactive molecules. This review aims to provide insight into the synthesis of bioactive molecules from the lignocellulose‐derived platform chemicals. Existing methodology and catalytic systems are summarized for the synthesis of targeted bioactive molecules from cellulose, hemicellulose, and lignin‐derived platform chemicals. The biological activities of bioactive molecules obtained from biomass, such as antioxidant, anti‐inflammatory, and anticancer properties, are discussed.

AbstractSeveral lines of evidence implicate that chronic periodontitis (CP) increases the risk of mental illnesses, such as anxiety and depression, yet, the associated molecular mechanism for this remains poorly defined. Here, it is reported that mice subjected to CP exhibited depression‐like behaviors and hippocampal memory deficits, accompanied by synapse loss and neurogenesis impairment in the hippocampus. RNA microarray analysis disclosed that albumin D‐site‐binding protein (DBP) is identified as the most prominently upregulated target gene following CP, and in vivo and in vitro immunofluorescence methods showed that DBP is preferentially expressed in microglia but not neurons or astrocytes in the hippocampus. Interestingly, it is found that the expression of DBP is significantly increased in microglia after CP, and knockdown of microglial DBP ameliorated the behavioral abnormality, as well as reversed the synapse loss and hippocampal neurogenesis damage induced by CP. Furthermore, DBP knockdown improved the CP‐induced hippocampal inflammation and microglial polarization. Collectively, these results indicate a critical role of DBP in orchestrating chronic periodontitis‐related behavioral abnormality, hippocampal synapse loss and neurogenesis deficits, in which the microglial activation may be indispensably involved.

AbstractLi‐ion battery performance relies fundamentally on modulation at the microstructure and interface levels of the composite electrodes. Correspondingly, the binder is a crucial component for mechanical integrity of the electrode, serving to interconnect the active material and conductive additive and to firmly attach this composite to the current collector. However, the commonly used poly(vinylidenefluoride) (PVDF) binder presents several limitations, including the use of toxic solvent during processing, a low electrical conductivity which for compensation requires the addition of carbon black, and weak interactions with active materials and collectors. This study investigates Poly(3,4‐ethylenedioxythiophene):poly[(4‐styrenesulfonyl) (trifluoromethylsulfonyl) imide] (PEDOT:PSSTFSI) as an alternative binder and conductive additive, in replacement of both PVDF and carbon black, in Li‐ion batteries with LiFe0.4Mn0.6PO4 at the positive electrode. Complex PEDOT:PSSTFSI significantly improves the electronic conductivity and lithium diffusion coefficient within the electrode, in comparison to standard PVDF binder and carbon black. This enhances significantly the electrochemical performance at high C‐rates and for high active mass loading electrodes. Furthermore, an excellent long‐range cyclability is achieved.

AbstractThe application life of Lithium–oxygen (Li–O2) batteries can be significantly affected by the formation and full decomposition of the discharge product Li2O2. After exsolution, the catalyst is designed to control the morphology and crystallinity of Li2O2 enhanced reversibility. In the perovskite exsolution system, the large amount of A‐site defects are introduced to induce the activation of lattice oxygen and the formation of oxygen vacancy, and promote the bimetallic exsolution from LaxFe0.8Cu0.1Co0.1O3. When x = 0.70, the distribution density of CuCo alloy and Cu metal increases and the size is smaller. Through exsolution process, the resulting oxygen vacancy and more doped ions exsolved expose a significant number of active sites that enhance the charge transfer and catalytic activity. Therefore, the charge resistance (Rct) smaller and can be better decomposed due to the generated small‐size Li2O2 with nano‐sheet morphology. Meanwhile, theoretical calculation shows that the exsolution of the catalyst enhances the adsorption of the intermediate LiO2 that makes the surface mechanism more advantageous. The reversibility of the battery is improved, and the cycle stability reaches 195 cycles. This work can serve as a guide for the development of exsolution that directs the design of high efficiency cathode catalyst.

Published: October 2024

AbstractAs solid‐state batteries (SSBs) emerge as leading contenders for next‐generation energy storage, chemo‐mechanical challenges and instabilities at solid‐solid interfaces remain a critical bottleneck. Ensuring sufficient interfacial contact within composite cathode architectures often requires the application of high stack pressures, posing a significant hurdle in the development of viable, large‐scale SSBs. In this work, the impact of stack pressure is investigated on the performance of solid‐state composite cathodes comprised of single‐crystal LiNi0.5Mn0.3Co0.2O2 (SC‐NMC532) active material particles and a Li6PS5Cl (LPSCl) solid electrolyte phase. By unraveling the complex interplay between stack pressure and microstructure‐dependent mechanisms, the profound influence on interfacial resistances, cathode utilization dynamics, current constriction effects, and lithiation heterogeneities are revealed. Through a comprehensive examination of coupled reaction kinetics and transport interactions at the electrode and particle length scales, the implications of stack pressure at different C‐rates and microstructural arrangements are elucidated, thereby delineating the limiting mechanisms that are prevalent at low stack pressures. This work underscores the critical role of optimizing the cathode microstructure to mitigate the chemo‐mechanical challenges associated with SSB operation at low stack pressures, offering valuable insights and design guidelines for the development of high‐performance SSBs.
Tuning the Solvation Structure of a Weakly Solvating Cyclic Ether Electrolyte for Wide‐Temperature Cycling of Lithium‐Sulfurized Polyacrylonitrile Batteries

Published: October 2024

AbstractSulfurized polyacrylonitrile (SPAN) cathodes in high energy‐density Li‐metal batteries have garnered widespread interest owing to their good cycling stability and moderately high capacities. However, their application is hindered by the low prevalence of advanced electrolytes that can simultaneously mitigate polysulfide generation at the cathode and stabilize the Li‐metal anode. Here, a weakly solvating electrolyte is presented, employing a single solvent tetrahydropyran (THP). The solvation structure is effectively tuned by adjusting the salt concentration to stabilize both the Li‐metal anode and SPAN cathode. This approach enables stable cycling with high SPAN loadings (≈5 mg cm−2) and lean electrolyte contents (≈5 µL mgSPAN−1) across a wide temperature range: 0 °C, room temperature, and 50 °C. A pouch cell with a high SPAN loading and a low electrolyte‐to‐SPAN (E/SPAN) ratio of 3 µL mg−1 shows a stable 79.1% capacity retention after 40 cycles. Additionally, THP can be effectively employed in localized high‐concentration electrolyte (LHCE) systems to reduce the diluent‐to‐solvent ratio for greater LHCE viability. The study demonstrates the potential of weakly solvating solvents in Li‐SPAN batteries, offering a pathway for their practical application.

Published: October 2024

ABSTRACTThe present study aimed to develop a standardized process map to produce a microbiologically safe and consumer‐acceptable Brukina beverage. Field interactions and observations were employed for the baseline data, while an improved production process was developed and utilized to produce a Brukina beverage. The microbial safety of the new approach was assessed by determining the total coliform, yeast and mold, as well as Staphylococcus aureus. A consumer preference test was conducted to validate the contribution of the improved and hygienic steps to the overall acceptability. The existing production processes for manufacturing Brukina beverage did not embrace Good Manufacturing Practices (GMPs) and as such, the resultant beverage was contaminated with coliforms and S. aureus. Moreover, the sensory characteristics including taste, mouthfeel, viscosity and overall acceptability, were negatively affected. The inclusion of food safety management practices and efficient production steps has a greater tendency of producing microbiologically safe and market‐acceptable fermented millet‐based beverages while safeguarding consumers’ health and satisfaction.

Published: October 2024

AbstractLead in drinking water can lead to serious health effects, including neurodevelopmental issues and heart disease. In December 2023, the U.S. Environmental Protection Agency (EPA) proposed the Lead and Copper Rule Improvements (LCRI), which lower the Lead and Copper Rule's (LCR's) lead action level (AL) from 15 parts per billion (ppb) to 10 ppb and require both first‐ and fifth‐liter sampling and 90th percentile compliance calculations based on the highest lead levels at sites with lead service lines. A methodology for estimating the likelihood a system will have an AL exceedance (ALE) under the LCRI was developed using Michigan LCR compliance data and applied to national LCR compliance data. Findings were compared to EPA's estimates, indicating EPA may have underestimated the percent of smaller systems (serving 3300) with ALEs and overestimated the percent of larger systems (serving > 10,000), thus underestimating costs and overestimating the benefits of this rulemaking.
The Investigation of the Effect of La3+, Eu3+, and Sm3+ Ions on Photoluminescence and Piezoelectric Behavior of RE1.90Y0.10Zr2O7 (RE: Eu, Sm and Y: La, Sm, Eu) Pyrochlore‐Based Multifunctional Smart Advanced Materials

ABSTRACTA series of compounds with the general formula RE1.90Y0.10Zr2O7 (where RE includes Eu, Sm and Y includes La, Sm, Eu) were synthesized using a solid‐state reaction method. These compounds were analyzed through differential thermal analysis (DTA), thermogravimetric analysis (TG), X‐ray powder diffraction (XRD), and scanning electron microscopy (SEM). Additionally, their dielectric constant, loss tangent, piezoelectric charge constant, and Curie temperature were measured using an LCR meter, d33 meter, and TG/DTA. X‐ray diffraction results indicated that all samples crystallize in a cubic pyrochlore structure. Photoluminescence studies revealed that Eu3+ ions predominantly contribute to the emission, whether as activators or co‐activators. Among the phosphors, Eu1.90La0.10Zr2O7 exhibited a significantly longer afterglow compared to Sm1.90Eu0.10Zr2O7 and Eu1.90Sm0.10Zr2O7. Conversely, Sm1.90Eu0.10Zr2O7 demonstrated luminescence intensity that was 20 times greater than that of Eu1.90La0.10Zr2O7 and Eu1.90Sm0.10Zr2O7. Furthermore, all samples with characteristic Eu3+ emissions also exhibited piezoelectric properties. Curie temperature (Tc) of Eu1.90La0.10Zr2O7, Sm1.90Eu0.10Zr2O7, and Eu1.90Sm0.10Zr2O7 are 770°C, 830°C, and 845°C, respectively. Therefore, Sm3+ ion improves piezoelectric properties and Curie temperature when doping into the Eu2Zr2O7 host crystal.
