Cellulose-based air-cathode loaded by in-situ hydrothermally synthesized NiFe2O4 for Al-air battery: Influence of surface chemistry on the electrochemical performance
No full textThe influence of the cellulosic fabrics (CF) surface chemistry on hosting nickel ferrite (NF) and its application in Al-air battery was studied. CFs were modified with acrylate monomer bearing positively (COOCH2CH2N+(CH3)3Cl−) or negatively (-COO(CH2)3SO3K) charged functional groups at different degrees of graft-polymerization. NF was in-situ hydrothermally synthesized into the un/grafted-CF followed by in-situ polymerization of polyaniline (PANi) to enhance the electric conductivity nine orders of magnitude. This via altering the electron transport mechanism from the tunnelling to the variable-range hopping mechanism for CF-NF and PANied-CF-NF, respectively. XRD confirmed a single phase of Trevorite (NiFe2O4). SEM images showed a dense deposition of NF on the anionic fabrics and TEM images demonstrated the change of NF shape (nanorice – nanoctahedrons) and size (9–75 nm) as a function of the surface chemistry. Anionic ACs showed higher Ni+2 and Fe+3 uptake compared to the cationic ones as confirmed by ICP-OES and XPS. Cyclic voltammetry showed that NF reduced oxygen to water through 2 × 2 electron pathway. Electrochemical performance of ACs showed a good correlation with the NF content to an extent. Highest current density (4 mA/cm2) and discharge time (13.8 h) were obtained from anionic AC compared to 1.7–2.5 h for blank and cationized ACs, respectively.The authors thank SRDA grant agency for support through project APVV-23-0534 and APVV-22-0062 .

Higher-order co-moment contagion during Trump's second presidential term: A trade policy uncertainty perspective
No full textDonald Trump's second presidential term continues to shape economic and trade policies as well as the dynamics of financial markets. In this paper, we examine whether U.S. trade policy uncertainty (TPU) under Trump's second term triggers financial contagion with asset classes through higher-order moments of asset returns. Our analysis extends recent studies that consider abnormal returns and the dynamics of asset correlations around the tariffs announcements and contributes to the literature that links political transitions and trade policy uncertainty with financial markets beyond the first and second moments by considering higher-order comoment contagion. Using daily data on U.S. equities, U.S. treasury and corporate bonds, U.S. dollar index, gold, crude oil, and Bitcoin, we consider the 2024 U.S. presidential election, 2025 presidential inauguration, and liberation day. Overall, the results show evidence of contagion in co-volatility, co-skewness, and co-kurtosis between US trade policy uncertainty and each of the examined assets following the three events. This highlights the substantial exposure of these assets to Trump's proposed tariffs, which has important implications for the decision-making processes of various economic actors
Freeze-dried pickering emulsions with curcumin: The role of stabilizers and cryoprotectants
Get PDFThis study investigated freeze-dried Pickering emulsions stabilized by a combination of cellulose nanocrystals (CNCs) and sodium caseinate (CAS), with encapsulated curcumin. Our approach focused on the order of CNC/CAS addition and its influence on emulsion properties, along with the effect of three different cryoprotectants (sucrose, d-mannitol, and d-glucose) on the preservation of emulsion droplets. In the study, controlled release of curcumin from freeze-dried emulsions was achieved, attributed to the composition of the stabilizing layer and the cryoprotectant used. The emulsions were partially able to withstand freeze-drying and could be redispersed to samples with droplets bigger than those observed before freeze-drying. The best-preserved droplets came from emulsions stabilized first by CNC particles and then by CAS addition and protected with d-glucose. Transdermal penetration studies revealed that curcumin was mainly present on the skin’s surface and at the stratum corneum, with limited penetration into deeper skin layers. Nevertheless, the samples showed outstanding antioxidant activity and no cytotoxicity effects, demonstrating their promising potential to positively influence the healing of the skin.This work was supported by the Czech Science Foundation (23-07425S).

Vacuum-filtered MXene/carbon nanotube composite films for Li-ion capacitors
Get PDFMXene has garnered significant attention for its applications in electrochemical energy storage devices, such as supercapacitors and Li-ion capacitors, owing to its high electrical conductivity and relatively high capacitance/capacity in both aqueous and organic electrolytes. Utilizing its two-dimensional (2D) structure, this study prepared vacuum-filtered MXene/carbon nanotube (MXene/CNT) composite films for Li-ion capacitors. The incorporation of CNTs plays a critical role in mitigating the restacking of MXene flakes and enhancing the structural integrity of the films. The MXene/CNT films were first characterized by using various physicochemical methods and evaluated in electrochemical half-cells. A Li-ion capacitor was subsequently fabricated by using the MXene/CNT-12% film as the negative electrode and mesoporous carbon as the positive electrode. The fabricated Li-ion capacitor demonstrates a specific capacitance of 26 F g–1, an energy density of 40.2 Wh kg–1, and a power density of 375 W kg–1at a current density of 0.5 A g–1. However, the electrochemical performance of the device is still limited by the layer-by-layer architecture of the MXene-based films, which hinders the efficient transport of electrolyte ions vertically through the layers.This work was supported by the Technology Agency of the Czech Republic (TH71020006 and TK03030157).

Pomological, biochemical and bioactive characteristics in fruits of quince cultivars grown in Türkiye
Get PDFQuince fruits (Cydonia oblonga), known for their nutritional value, with intense aroma, flavour and tartness, are commonly used in jams, jellies, compotes, juices and alcoholic drinks. The study aimed to assess the quality of quince fruits through a pomological study and biochemical analysis. Skin and juice of eight commercially known cultivars (from Pozanti, Türkiye) were analysed. The results revealed the pomological and biochemical variations among the studied cultivars. Among cultivars, 'Ekmek' had the highest fruit weight, while 'Tekec' exhibited significantly lower fruit weight. In terms of biochemical analysis, pH was in the range from 3.56 (Áltinayva') to 3.04 ('Osmancik'), while lower pH indicates a tart flavour of fruits. Acidity peaked in 'Ekmek' and 'Kalecik' cultivars, whilst soluble solids content (SSC) value was highest in Ácem' cultivar (20.20%), suggesting sweeter fruit taste. 'Kalecik' cultivar showed highest ascorbic acid content (21.41 mg ∙ 100 g-1 fresh fruit). As for antioxidant parameters, antioxidant capacity (AC) was highest in Ácem' cultivar, followed by 'Ekmek' and 'Kalecik', and Áltinayva' showed the lowest value of AC. Similarly, the highest total phenolic content was determined for Ácem' cultivar, and thus this indicator also confirmed the excellent properties and potential of this cultivar. These findings underscore the importance of genetic selection of quince fruits for optimising traits such as fruit size and weight, sweetness, acidity and antioxidant properties to meet the quality, consumer preferences and market demands.Cukurova Universit
Worldwide Soundscapes: A synthesis of passive acoustic monitoring across realms
Get PDFAim: The urgency for remote, reliable and scalable biodiversity monitoring amidst mounting human pressures on ecosystems has sparked worldwide interest in Passive Acoustic Monitoring (PAM), which can track life underwater and on land. However, we lack a unified methodology to report this sampling effort and a comprehensive overview of PAM coverage to gauge its potential as a global research and monitoring tool. To address this gap, we created the Worldwide Soundscapes project, a collaborative network and growing database comprising metadata from 416 datasets across all realms (terrestrial, marine, freshwater and subterranean).
Location: Worldwide, 12,343 sites, all ecosystem types. Time Period: 1991 to present. Major Taxa Studied: All soniferous taxa. Methods: We synthesise sampling coverage across spatial, temporal and ecological scales using metadata describing sampling locations, deployment schedules, focal taxa and audio recording parameters. We explore global trends in biological, anthropogenic and geophysical sounds based on 168 selected recordings from 12 ecosystems across all realms.
Results: Terrestrial sampling is spatially denser (46 sites per million square kilometre—Mkm2) than aquatic sampling (0.3 and 1.8 sites/Mkm2 in oceans and fresh water) with only two subterranean datasets. Although diel and lunar cycles are well sampled across realms, only marine datasets (55%) comprehensively sample all seasons. Across the 12 ecosystems selected for exploring global acoustic trends, biological sounds showed contrasting diel patterns across ecosystems, declined with distance from the Equator, and were negatively correlated with anthropogenic sounds.
Main Conclusions: PAM can inform macroecological studies as well as global conservation and phenology syntheses, but representation can be improved by expanding terrestrial taxonomic scope, sampling coverage in the high seas and subterranean ecosystems, and spatio-temporal replication in freshwater habitats. Overall, this worldwide PAM network holds promise to support cross-realm biodiversity research and monitoring efforts.We acknowledge the NFDI Consortium Earth System Sciences\u2014NFDI4Earth, coordinated by TU Dresden, funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation)\u2014project number: 460036893.

Integrative miRNOMe profiling reveals the miR-195-5p-CHEK1 axis and its impact on luminal breast cancer outcomes
Get PDFThe luminal subtype (estrogen receptor-positive, ER+) is the most common and the most heterogeneous type of breast carcinoma (BC) in women. During our study, we determined expression levels of all microRNAs (miRNome) in 101 ER+ BC samples and identified 25 miRNAs being associated with proliferative markers. Using comprehensive in silico analyses we prioritized CHEK1, CDC25A, and CCNE1 as candidate genes affecting the proliferation of ER+ BC, with two microRNAs from the miR-497∼195 cluster identified as their potential regulators. In a cohort of 217 patients, we found a significant association between high expression of CHEK1 and shorter relapse-free survival (RFS) in luminal BC patients treated with adjuvant chemotherapy, especially in patients with luminal A subtype. In patients treated with neoadjuvant therapy, the opposite role for RFS was observed for hsa-miR-195-5p. Subsequently, we confirmed the potency of hsa-miR-195-5p to inhibit the expression of CHEK1 in vitro. Moreover, the specific Chk1 inhibitor rabusertib (LY2603618) significantly enhanced the efficacy of doxorubicin in both ER+ and ER- cell lines. In summary, we have identified the association of a specific miRNA profile with highly proliferative luminal BCs and demonstrated the ability of hsa-miR-195-5p to inhibit CHEK1 expression in BC in vitro, underlining the importance of CHEK1 expression and its inhibition for prognosis and treatment of patients with luminal BCs.This work was funded by the Czech Health Research Council grant no.

Effective vibration sensing nanocomposite sheets based on Poly(vinylidene fluoride-co-hexafluoropropylene) matrix and SrTiO3 nanoparticles grafted with 2,2,2-trifluoroethyl methacrylate nanoscale coating
No full textStructural, thermal and mechanical properties of poly(vinylidene fluoride-co-hexafluoropropylene) (P(VDF-HFP))/strontium titanate (ST) nanocomposites with different weight ratios were investigated in this research. ST particles were modified for the first time by poly(2,2,2-Trifluoroethyl methacrylate) (PTFEMA) nanoscale coating. The successful polymerization from the surface using atom transfer radical polymerization (ATRP) approach was investigated using 1H nuclear magnetic resonance and gel permeation chromatography, by means of monomer conversion and molecular weight/polydispersity index, respectively. The presence of the nanometer thin PTFEMA coating was confirmed using transmission electron microscopy. Scanning electron microscope with energy-dispersive spectroscopy was used for evaluation of the individual elements such as carbon, fluorine and oxygen. Fabricated nanocomposites were thoroughly characterized using Fourier transform infrared spectroscopy to show, that even a small amount of ST or ST-PTFEMA decreased the amount of β-phase content compared to the pristine polymer. However, with higher filler amounts, β-phase remained same or slightly decreased. Mechanical properties and glass transition temperature (Tg) were determined by dynamic mechanical analysis. For the pure polymer at 1 Hz the Tg was −35.1 °C, while for nanocomposites Tg were within the range of −35.9 to −35.0 °C for those with ST and −37.1 to −35.8 °C for those with ST-PTFEMA, showing the reinforcement of the fabricated nanocomposites. The tensile test showed that addition of 5 wt % of ST-PTFEMA allowed nanocomposite to keep almost same strain at break (940 ± 40 %) value as pristine P(VDF-HFP) (990 ± 30 %), while nanocomposite with 5 wt % of neat ST value decreased to (640 ± 20 %). Furthermore, strain at break value of nanocomposites with increasing content (10 and 20 wt%) of neat ST significantly dropped, while those with ST-PTFEMA analogues were able to keep higher values even with increasing content of those particles, thus those are suitable for further treatment techniques such as additional stretching. Finally, the vibration sensing activity of the nanocomposites were measured, where highest d33 was achieved by nanocomposite with 5 wt% ST-PTFEMA 21.4 ± 1.3 pC/N which was significantly higher than d33 for neat PVDF 14.4 ± 1.4 pC/N as well as corresponding non-modified analogues showing 18.6 ± 1.9 pC/N.Bundesministerium für Bildung, Wissenschaft und Forschung, BMBWF; OeAD-GmbH, OEAD; Bundesministerium für Bildung, Wissenschaft, Forschung und Technologie, BMBWF; Ministerstvo Školství, Mládeže a Tělovýchovy, MŠMT; DKRVO, (RP/CPS/2024-28/003, VEGA 2/0137/23); Grantová Agentura České Republiky, GAČR, (23-07425S, MPC-2023-01092); Grantová Agentura České Republiky, GAČR; Tomas Bata University in Zlín, TBU, (IGA/CPS/2023/007); Tomas Bata University in Zlín, TBUInternal Grant Agency of Tomas Bata University in Zln [IGA/CPS/2023/007]; Ministry of Education, Youth and Sports of the Czech Republic-DKRVO [RP/CPS/2024-28/003]; Czech Science Foundation [23-07425S]; AKTION Osterreich - Tschechien - OeAD - Austria's Agency for Education and Internationalisation - Federal Ministry of Education, Science and Research (BMBWF) [MPC-2023-01092]; VEGA [2/0137/23
Unexpected processing-induced particle/matrix interactions in magnetic composites based on thermoplastic matrix
No full textUnderstanding processing-induced changes in the polymer composites is of the utmost necessity as it affects the final properties and the reliability of the products. Despite their importance, related investigations are frequently overlooked, especially in the case of magnetorheological elastomers (MREs). In this study, the processing-induced changes were investigated within an isotropic MRE based on a thermoplastic elastomer (TPE) matrix loaded with carbonyl iron (CI) microparticles. Systematic thermomechanical tests in the molten state were used to mimic the processing conditions, revealing the time evolution of the particle/matrix interactions. The interactions manifested as an increase in the viscoelastic properties, which was attributed to the development of a secondary network composed of the confined polymer chains in the vicinity of the CI particles. The restricted mobility improved the reinforcing effect and structural integrity but diminished the field-induced stiffening of the composite, i.e., the magnetorheological effect. The existence of the particle/matrix covalent bonding was postulated and explained based on the coupling reaction between the thermomechanically-induced radicals formed in the polymer chain and the alkoxyl radicals on the surface of the CI particles. The new findings are highly relevant for the further development of reprocessable and recyclable TPE-based MREs, while the robust measuring protocol is deemed to be implementable for studying particle/matrix interactions in diverse composite systems.Czech Science Foundation [23-07244S]; Ministry of Education, Youth and Sports of the Czech Republic [RP/CPS/2024-28/007]; Internal Grant Agency of Tomas Bata University in Zlin [IGA/CPS/2023/004]; Slovenian Research Agency Core Funding [P2-0082]plasma surface engineering; Univerzita Tomáše Bati ve Zlíně, UTB; Ministerstvo Školství, Mládeže a Tělovýchovy, MŠMT; Grantová Agentura České Republiky, GAČR, (23-07244S, RP/CPS/2024-28/007); Grantová Agentura České Republiky, GAČR; Tomas Bata University in Zlín, TBU, (IGA/CPS/2023/004); Tomas Bata University in Zlín, TBU; Slovenian Research Agency Core Funding, (P2-0082
Sterilized processed cheese: Principles, technological aspects, and properties: A review
Get PDFSterilized processed cheese is a dairy product with prolonged shelf life compared to regular processed cheese. The extension of durability is made possible by the thermosterilization of processed cheese, while regular processed cheese is submitted to pasteurization process during manufacturing. Sterilized processed cheese can be classified as long-life foods and their shelf life may reach up to 24 months, if stored at ambient temperature (approx. 25 ± 1 °C). This fact is an advantage over regular processed cheese, which has a shelf life of only around 6 months. Sterilized processed cheese finds application in everyday life when refrigeration facilities are not available; i.e., it is intended for regular retail. However, their most important use is for storage in state material reserves and, moreover, for catering for members of the armed forces and/or members of the integrated rescue system. This review aimed to gather general information on sterilized processed cheeses, their characterization, usage and production. Furthermore, the review discusses the principles of sterilization and factors affecting the course of sterilization focusing on the setting the sterilization limits and sterilization parameters in order to maximize end-product quality. Moreover, last part of the review is devoted to the effect of sterilization and long-term storage on the qualitative parameters of sterilized processed cheese.Ministry of Defence of the Czech Republic; Army of the Czech RepublicMinisterstvo Obrany České Republiky, MOČ
