Study of the nano zero-valent iron stabilized by carboxymethyl cellulose loaded on biochar for remediation of Cr(VI)-contaminated groundwater

Hexavalent chromium (Cr(VI)) contamination in groundwater poses a significant threat to human and environmental health. In this study, nanoscale zero-valent iron stabilized by carboxymethyl cellulose loaded on biochar (CMC-nZVI@BC) was used as an in-situ reaction zone material to remove Cr(VI) from groundwater. The experimental results demonstrated that CMC-nZVI@BC effectively removed 99.9 % of Cr(VI) within 180 min, which was 22.4 % and 10.7 % higher than that of nZVI@BC and CMC-nZVI, respectively. Physisorption and chemisorption were responsible for Cr(VI) removal. Electrochemical analysis showed that the number of transferred electrons in Cr(Ⅵ) removal by CMC-nZVI@BC was approximately 47 times greater than that of BC, which indicated that BC mainly acted as an electron shuttle to facilitate the electron transfer between nZVI and Cr(VI). The maximum breakthrough C/C0 values of CMC-nZVI@BC in coarse and medium sand were 0.86 and 0.72, respectively, demonstrating its good mobility. The in-situ reaction zone based on CMC-nZVI@BC was suitable for media with particle size greater than 0.25 mm. The reaction zone continuously removed Cr(VI) from the groundwater, and the effective remediation periods in the coarse sand and medium sand were 4 and 6 days, respectively. This study confirms the great potential of CMC-nZVI@BC for contaminated groundwater remediation.

Enhancing intelligent transport systems: A cutting-edge framework for context-aware service management with hybrid deep learning

This study presents a comprehensive framework for optimizing intelligent transport systems (ITS) by integrating advanced communication and information technologies into vehicles, roads, and infrastructure. The primary goal is to enhance transportation efficiency, safety, and environmental sustainability while improving overall mobility for people and goods. Leveraging contextual information, the framework offers personalized, proactive services such as real-time traffic updates, route recommendations, and parking availability. Additionally, it enhances safety and security by providing early hazard warnings and adapting to changing road conditions. Our proposed framework utilizes the enhanced coral reef optimization (ECRO) algorithm to efficiently group vehicles for energy-saving data collection, maximizing information gathering efficiency. Collected data is then transmitted to a central data gathering center via a sink node optimized through the modified pelican optimization (MPO) algorithm, considering various vehicle node design constraints. An incident detection module accurately classifies and detects road incidents, enabling timely emergency service requests and alternate route recommendations. To facilitate incident detection, we introduce the deep Rigdelet neural network (DRNN), a novel deep learning technique tailored for decision-making in incident classification. We validate our framework's performance through NS-2 simulations using the SUMO traffic generator, demonstrating its effectiveness in meeting quality of service (QoS) metrics. Through comparative analysis with existing frameworks, our proposed approach stands out for its superior performance and ability to optimize ITS operations.

Projecting traffic flows for road-based passenger transport in Europe for the analysis of climate impact

Road-based transport is a significant contributor to global transport emissions of greenhouse gases and local pollutants, thus contributing to the environmental impact of the mobility of people and goods. In order to develop strategies to mitigate this impact, it is necessary to build reliable emission inventories that include sector-specific emissions. Furthermore, the methods for creating these inventories should be applicable for forecasts and scenario calculations to facilitate the evaluation of pathways towards a more sustainable transport system. The study at hand proposes a model-based framework to predict travel demand and its spatial distribution for a bottom-up calculation of road transport emissions in Europe. With this framework, it is possible to calculate emissions based on the road network structure, traffic flows and vehicle types. In order to demonstrate the applicability of the framework for scenario calculations, it is applied to three exemplary scenarios where population data is modified. With the developed methodology, a tool for the large-scale assessment of emissions from road transport is provided, which is able to simulate the impact of socio-economic and economic changes on these emissions.

Single Apheresis Session on the 4th Day of Granulocyte Colony-Stimulating Factor Administration Seems Convenient to Collect Enough Peripheral Blood Stem Cells from Healthy Donors

Background: To minimize adverse events of peripheral blood stem cell (PBSC) collection in healthy donors, it is reasonable to limit the total dose of granulocyte colony-stimulating factor (G-CSF) and/or the number of apheresis days without decreasing of PBSCs yield. Therefore, we have started to collect G-CSF induced PBSCs on day 4 instead of on day 5. So, we retrospectively aimed to investigate the results of this 4-day G-CSF administration. Study Design and Methods: Seventy-six healthy donors who performed on G-CSF induced PBSCs donation consecutively between January 2020 and July 2022 were included in this study. G-CSF (filgrastim) at 2 × 5 µg/kg/day subcutaneously was applied. Apheresis started on day 4. Results: Sixty-nine (90.8%) of 76 donors provided enough PBSCs on day 4 apheresis session. Younger age (p = 0.004), higher PB CD34+ cell count on the 4th day of G-CSF (p < 0.001), and male donor (p = 0.010) were correlated with increased amounts of PBSCs yield. Univariate and multivariate logistic regression analyses to predict very good mobilizers (collected PBSCs ≥8 × 106/kg after the first apheresis) were performed. In multivariate logistic regression analyses, male sex (p = 0.004), PB CD34+ cell count ≥100/µL on the 4th day of G-CSF (p < 0.001), and glomerular filtration rate ≥115 mL/min (p = 0.031) were found to be independent predicting factors to demonstrate very good mobilizer. Conclusion: It seems that starting the apheresis on the 4th day of G-CSF administration is effective and to provide minimal G-CSF exposure in healthy donors.

Self‐doped conjugated polymers with electron‐deficient quinone units for enhanced electron transport in highly efficient organic solar cells

AbstractOrganic solar cells (OSCs) have attracted significant attention as a burgeoning flexible technology, owing to their advanced power conversion efficiencies. Moreover, interface materials play a crucial role in optimizing energy level alignment between the active layer and electrodes, thereby enhancing carrier extraction within the device and improving efficiency. However, current methodologies for fabricating electron‐transport materials with superior mobility are still limited compared with those for hole‐transport materials. In this study, a benzodifurandione (BFDO)‐derived building block with quinone resonance property and strong electron‐withdrawing capability was synthesized. Two conjugated polymers, namely PBFDO‐F6N and PBFDO‐F6N‐Br, were prepared, both of which exhibited good electron mobility and exceptional interface modification capabilities. A comprehensive investigation of the interaction between the interface layer and the active layer revealed that PBFDO‐F6N induced doping at the acceptor interface. Additionally, the high mobility of PBFDO‐F6N facilitated efficient carrier extraction at the interface. Consequently, the application of PBFDO‐F6N as the cathode interface layer for PM6:BTP‐eC9‐based OSC devices resulted in a remarkable efficiency of 18.11%. Moreover, the device efficiency remained at ∼96% even at a PBFDO‐F6N interface thickness of 50 nm, demonstrating the great potential of this material for large‐scale device preparation.

CRGD-modified hybrid lipopolymeric nanoplexes for gene editing in the posterior segment of the eye

Eye-related diseases, specifically retinal dystrophy (RD) conditions, are the leading cause of blindness worldwide. Gene addition, regulation, or editing could potentially treat such diseases through gene expression regulation. CRISPR/Cas9 gene editing is one of the most prominent and precise gene editing tools which could be employed to edit genes related to the dystrophic condition. However, CRISPR/Cas9 faces in vivo delivery challenges due to its high molecular weight, negative charge, prone to degradation in the presence of nucleases and proteases, poor cellular degradation, etc., which makes it challenging to adopt for therapeutic applications. We developed cRGD-modified lipopolymeric nanoplexes loaded with Cas9 RNPs with a particle size and zeta potential of 175 ± 20 nm and 2.15 ± 0.9 mV, respectively. The cRGD-modified lipopolymeric nanoplexes were stable for 194 h and able to transfect >70 % ARPE-19 and NIH3T3 cells with an Indel frequency of ~40 % for the VEGF-A gene. The cRGD-modified lipopolymeric nanoplexes found good vitreous mobility and could transfection retinal cells in vivo after 48 h of intravitreal injection in Wistar Rats. Moreover, in vivo VEGFA gene editing was ~10 % with minimal toxicities. Collectively, the cRGD-modified lipopolymeric nanoplexes were found to have extreme potential in delivering CRISPR/Cas9 RNPs payload to the retinal tissues for therapeutic applications.

Poor Mobilization-Associated Factors in Autologous Hematopoietic Stem Cell Harvest.

Peripheral blood stem cell transplantation (PBSCT) is an important therapeutic measure for both hematologic and non-hematologic diseases. For PBSCT to be successful, sufficient CD34+ cells need to be mobilized and harvested. Although risk factors associated with poor mobilization in patients with hematologic diseases have been reported, studies of patients with non-hematologic diseases and those receiving plerixafor are rare. To identify factors associated with poor mobilization, data from autologous PBSC harvest (PBSCH) in 491 patients were retrospectively collected and analyzed. A multivariate analysis revealed that in patients with a hematologic disease, an age older than 60 years (odds ratio [OR] 1.655, 95% confidence interval [CI] 1.049-2.611, p = 0.008), the use of myelotoxic agents (OR 4.384, 95% CI 2.681-7.168, p < 0.001), and a low platelet count (OR 2.106, 95% CI 1.205-3.682, p = 0.009) were associated with poor mobilization. In patients with non-hematologic diseases, a history of radiation on the pelvis/spine was the sole associated factor (OR 12.200, 95% CI 1.934-76.956, p = 0.008). Among the group of patients who received plerixafor, poor mobilization was observed in 19 patients (19/134, 14.2%) and a difference in the mobilization regimen was noted among the good mobilization group. These results show that the risk factors for poor mobilization in patients with non-hematologic diseases and those receiving plerixafor differ from those in patients with hematologic diseases; as such, non-hematologic patients require special consideration to enable successful PBSCH.

Effect Of Improving Lumbar Mobility, Spinal Stability ; With Core Stability Training To Achieve Per-sonal Best Runner

Running consists of simple basic movements, and to achieve these simple basic movements requires good mobility and stability, because the weakening of mobility and stability of the body causes misalignment or weakness of the legs so as to interfere with the absorption or propulsion phase in leg movement while running. Apply appropriate exercise methods to improve lumbar mobility and spinal stability. One training method that can be used is the core stability training method. Core stability is an exercise model to improve the ability to control the position of trunk movement through the pelvis and legs to allow optimal motion production. This study aims to ascertain whether core stability training can improve lumbar mobility and spinal stability in running athletes. The study used an experimental method with a research pattern using a group pretest-posttest design. 10 running athletes were sampled according to the criteria to be treated in the form of core stability training for 6 weeks. The athletes were assessed before and after training using the Functional Reach Test and Unilateral Hip Bridge Endurance. This study showed that there was a significant effect between core stability training and lumbar mobility (P = 0.000) and spinal stability (P = 0.000) in athletes. The results of this study show that the application of core stability exercises can increase the ability of lumbar mobility and spinal stability, so if the core stability exercises are done properly, they can increase stability in the spine and mobility in the lumbar, which causes dynamic limb movement to be more efficient. Key Words: athletics; Core Stability; Lumbar Mobility; spine stability.

N-type semiconducting hydrogel.

Hydrogels are an attractive category of biointerfacing materials with adjustable mechanical properties, diverse biochemical functions, and good ionic conductivity. Despite these advantages, their application in electronics has been restricted because of their lack of semiconducting properties, and they have traditionally only served as insulators or conductors. We developed single- and multiple-network hydrogels based on a water-soluble n-type semiconducting polymer, endowing conventional hydrogels with semiconducting capabilities. These hydrogels show good electron mobilities and high on/off ratios, enabling the fabrication of complementary logic circuits and signal amplifiers with low power consumption and high gains. We demonstrate that hydrogel electronics with good bioadhesive and biocompatible interface can sense and amplify electrophysiological signals with enhanced signal-to-noise ratios.

Facile construction and enhanced catalytic activity of Co-Mn oxide with rich amorphous/crystalline interfaces for propane oxidation

Cobalt-manganese (Co-Mn) composite oxides show high potential for the catalytic oxidation of volatile organic compounds (VOCs). However, the low defect content and poor oxygen mobility of perfect spinel structure crystalline always make it difficult to effectively activate C–H bonds of propane. Here, the catalyst with rich amorphous MnOx/crystalline Co3O4 interfaces was prepared, and the catalytic combustion activity for propane was determined. The rich amorphous/crystalline interfaces CMO-400 (i.e. Co-Mn oxide calcined at 400 °C) catalyst exhibited the best catalytic activity for propane with T90 of 200 °C among all bimetallic Co-Mn oxides. Various characterizations and corresponding results have demonstrated that the abundant amorphous/crystalline interfaces could improve the catalytic performances, attributed to high oxygen vacancy concentration, low temperature reducibility, weak Mn−O bond strength, and good surface lattice oxygen mobility. It is noteworthy that the interface engineering of amorphous/crystalline is an effective strategy in VOCs catalytic oxidation.

Thienyl naphthodipyrrolopyrrole (TNDP)-based polymers semiconductor for n-type OFETs

Naphthodipyrrolopyrrole (NDP)-based materials as the n-type semiconductor materials are investigated, which present a good electron transport mobility. However, all the reported NDP were phenyl-substituted ones (PhNDP). Compared to the phenyl substituted chromophore, the thiophene substituted ones were often more promising due to its small size, S⋯S interaction, as well as the electron-rich behavior for the thiophene. Thus, in this work the new chromophore thiophene-substituted NDP (TNDP) was designed and synthesized for the first time via Knoevenagel reaction. In addition, two donor-acceptor typed copolymers PNDP-2T and PNDP-IDT containing TNDP were prepared. The result showed that the two polymers present not only a good aggregation and strong intramolecular charge transfer (ICT) effect, but also a low lowest unoccupied molecular orbital (LUMO) ∼ -4.17 eV. This is advantageous for the charge transport within the single molecules as well as across the neighboring polymer chains. In addition, the low LUMO energy level is beneficial for the electron injection from electrode into the semiconductor layer. As a consequence, both polymers presented n-type behavior. The electron transport mobility of PNDP-IDT was up to 0.99 cm2 V−1 s−1, which is among the highest electron mobility reported for conjugated polymers. In addition, this value is higher than the PNDP-based polymers with similar chemical structure. This work clearly shows that TNDP is an appealing electron-deficient building block for novel π-conjugated polymers with application potential in the n-channel semiconductors.

Study on the Design, Synthesis, Bioactivity and Translocation of the Conjugates of Phenazine-1-carboxylic Acid and N-Phenyl Alanine Ester.

The natural pesticide phenazine-1-carboxylic acid (PCA) is known to lack phloem mobility, whereas Metalaxyl is a representative phloem systemic fungicide. In order to endow PCA with phloem mobility and also enhance its antifungal activity, thirty-two phenazine-1-carboxylic acid-N-phenylalanine esters conjugates were designed and synthesized by conjugating PCA with the active structure N-acylalanine methyl ester of Metalaxyl. All target compounds were characterized by 1H NMR, 13C NMR and HRMS. The antifungal evaluation results revealed that several target compounds exhibited moderate to potent antifungal activities against Sclerotinia sclerotiorum, Bipolaris sorokiniana, Phytophthora parasitica, Phytophthora citrophthora. In particular, compound F7 displayed excellent antifungal activity against S. sclerotiorum with an EC50 value of 6.57 µg/mL, which was superior to that of Metalaxyl. Phloem mobility study in castor bean system indicated good phloem mobility for the target compounds F1-F16. Particularly, compound F2 exhibited excellent phloem mobility; the content of compound F2 in the phloem sap of castor bean was 19.12 μmol/L, which was six times higher than Metalaxyl (3.56 μmol/L). The phloem mobility tests under different pH culture solutions verified the phloem translocation of compounds related to the "ion trap" effect. The distribution of the compound F2 in tobacco plants further suggested its ambimobility in the phloem, exhibiting directional accumulation towards the apical growth point and the root. These results provide valuable insights for developing phloem mobility fungicides mediated by exogenous compounds.

Modeling and performance investigation of novel inorganic Cs4CuSb2Cl12 nanocrystal perovskite solar cell using SCAPS-1D

For the next generation of photovoltaic devices, perovskite solar cells (PSCs) appear as a good choice because they are simple and convert energy to electricity very efficiently. Recent years have seen a great deal of interest in organic-inorganic lead halide perovskites due to their exceptional optoelectronic properties. Nonetheless, additional commercialization of the Pb element is still restricted by its inevitable toxicity. To address the instability and toxicity of the lead hybrid perovskite, it is imperative to produce entirely inorganic lead-free perovskite nanocrystals. Cs4CuSb2Cl12 offers promising qualities and strong stability against light, heat, and humidity to overcome these drawbacks. It possesses an efficient photo-generated carrier and good carrier mobility. In this study, a lead-free perovskite solar cell with the novel configuration of FTO/WS2/Cs4CuSb2Cl12/CuSbS2/Ni has been optimized using SCAPS-1D simulation software and investigates the potential of Cs4CuSb2Cl12 nanocrystal solar cell. The impact of different characteristics of charge transport materials on Cs4CuSb2Cl12 nanocrystal solar cells has been reported. Additionally, the study computationally optimizes the thickness of perovskite layer, doping concentration, defect density, and other input parameters to propose an effective PSC with power conversion efficiency of 23.10 %, Voc of 1.1675V, and FF of 83.33 %.

Low-temperature synthesis and properties of high-purity boron nitride microspheres

Boron nitride (BN) has excellent high temperature resistance, thermal conductivity, strong insulation, and wave-transparent properties. Spherical BN is an essential filler in polymer matrix composites due to good particle mobility and high filler content. In this paper, we present a large-scale preparation for BN microspheres with uniform particle size distribution in the range of 1.0–2.8 μm via solvothermal method at low cost and high yield (∼90%), which is two orders of magnitude lower than the diameter of the spherical BN prepared by other methods. BN microspheres can achieve good crystallinity (>70%) and high purity (>99.9%) at 800 °C. The temperature resistance study showed that the BN microspheres could maintain the dense particle morphology at 1200 °C. In addition, the prepared BN microspheres have good dielectric and thermal conductivity properties (dielectric constant ∼3.4, dielectric loss ∼2.0 × 10−3, and thermal conductivity of 9.8 W m−1 K−1), which show great potential in the field of wave-transparent and thermal conductive composites. The synthesis process of BN microspheres proposed in this study provides a new idea for the preparation of ceramic micro or nano materials by polymer-derived ceramics.

Evaluation of blood cell count using an automatic hematology analyzer to optimize collection of peripheral blood progenitor cells by leukapheresis

BackgroundAutologous stem cell transplantation is a treatment modality for several diseases. Prediction of successful mobilization may be useful to optimize hematopoietic stem cell collection. Study design and methodsThis was a retrospective study with data from transplantation candidates between September 2015 and December 2021 being analyzed. The medical record of each patient was reviewed to mine mobilization information. The laboratory data analyzed were CD34+ cell enumeration and pre-collection peripheral blood cell count. The primary outcome, good mobilization, was defined as a CD34+ cell count ≥20/μL. ResultsThis study included 807 patients. Increased patient weight, low mean corpuscular volume, high nucleated red blood cells, peripheral blood mononuclear cell and immature granulocyte counts were significantly associated with good mobilization. In addition, patients diagnosed with multiple myeloma were two times more likely to be good mobilizers than patients with lymphoma. The model was applied to a validation set to identify patients who underwent apheresis (CD34+ cell count ≥10 µL), resulting in a sensitivity of 69 %, a specificity of 95 %, positive predictive value of 98 %, and a negative predictive value of 50 %. ConclusionSuccess in mobilization was greater in patients who underwent the first mobilization cycle and who had a diagnosis of multiple myeloma. Furthermore, higher body weight, and nucleated red blood cells, immature granulocytes and mononuclear cell counts, as well as low mean corpuscular volumes, were associated with successful mobilization.

Commemoration and radical right-wing populism in European borderlands

Abstract The success of radical right-wing populist (RRWP) parties is based on discourses displaying “power geometries” (Massey 1993, 1999). These involve the representation of power relations, with on one side a globalized elite, boosting the mobility of human beings, goods and capital across borders, and on the other side, a territorially embedded people subject to this borderless mobility. Power geometries can also be used to approach the chameleonic behavior of RRWP politicians and their allies in the political space. The article uses this concept to interpret the attitude of the Trieste City Executive and the reactions to it when it commemorated a past connected to Italian fascism. The results show that the power geometries involving the RRWP and their allies in European borderlands can lead to discursive ambivalence in two overlapping spaces: the territorial and state-bordered space of representative democracy, and the topological and cross-border space of para-diplomacy.

Experimental Characterisation of BGBC OTFT for Indoor CO&lt;sub&gt;2&lt;/sub&gt; Gas Sensing

Global warming is a concern nowadays due to excessive release of harmful gasses to the environment, leading to greenhouse effect phenomena worldwide. Based on the data provided by global pollution agencies, the release of greenhouse gasses to the atmosphere is the main cause of pollution and the increase in atmospheric temperature due to warming. Greenhouse gasses (GHGs) contents released to the environment is worrying, with carbon dioxide (CO2) is reported at the highest concentration compared to other gasses. There are many studies conducted to develop and evaluate the performance of harmful gas sensors incorporating inorganic and organic semiconductive materials. Organic semiconductors (OSCs) are environmentally friendly materials, relatively cheaper technology, and comprised of a wide range of materials with good carrier mobility. Therefore, in this work, Organic Thin Film Transistor (OTFT) is developed for gas sensor application. As global warming is becoming more serious, this solution is instead a sustainable solution to the environment, as organic molecules which are held together via Van der Waals bond are easily processed via low-temperature deposition and solution processing as compared to more complicated processes involved in conventional inorganic counterpart. In addition, the developed sensor is generally robust due to the ability to withstand high humidity conditions and can be fabricated on flexible substrates. In this work, suitable materials are identified in basic OTFT construction, which are the electrodes, dielectric and substrate. The scope is mainly focusing on the development of bottom gate OTFT construction, incorporating p-type active material which are Trisisopropylsilylethynyl Pentacene (TIPS Pentacene), Aluminium (Al) as drain and source electrodes, PEDOT: PSS as gate electrode and Polyvinyl alcohol (PVA) as gate dielectric. The materials in bottom gate bottom contact (BGBC) configuration, fabricated via screen printing technique is experimentally tested towards CO2 detection. CO2 is initially detected at 1618 ppm with contact resistance of 15 kΩ, and at 10 ml/minute flow rate, the developed configuration is demonstrated able to achieve sensitivity of 2.069 Ω/ppm. In conclusion, the studied BGBC OTFT has demonstrated suitability and applicability in CO2 gas sensing for sustainable environmental condition monitoring, that could lead to safer environment for the living things on earth. With the proposed dimensions, in the future it is possible to proceed with this work to be fabricated by using more advanced techniques such as photolithography and many others.
