The ex-situ catalytic pyrolysis of waste polyolefin plastics holds promise for producing aromatics and light olefins, with potential integrations in the low-carbon olefin processing industry for producing ethylene, propylene, butadiene, or aromatic hydrocarbons. Employing ZSM-5(50) zeolite, selected for its substantial specific surface area and total pore volume, facilitated the catalytic pyrolysis of household plastic waste through an ex-situ pyrolysis-catalysis approach. This study explored the impact of operating parameters, namely pyrolysis temperature (T1), catalytic vapor upgrading temperature (T2), and the catalyst/plastic (C/P) mass ratio, on pyrolysis product yields and distributions. Higher catalytic vapor upgrading temperatures benefited gas production, accompanied by a notable decrease in C4 content in gaseous products. A larger C/P mass ratio provided more active sites for pyrolysis reactions, but higher reaction temperatures induced coke formation on the catalyst, leading to ZSM-5(50) deactivation and inhibiting further gas production. Positive effects of catalytic vapor upgrading temperature and the C/P mass ratio were observed for the concentration of BTX in the produced oil. The quadratic fitting was engaged in characterising the reaction conditions. Specifically, the 500-550-0.25 run achieved the maximum C2 yield of 30.3 wt.%, the 500-350-0.4 run obtained the highest yield of C3 and C4 of 75.4 wt.%, and the run of 575-450-0.25 yielded the highest amount of BTX of 17.2 wt.%. These findings provide valuable insights into the designated conditioning of catalytic pyrolysis for plastic waste valorisation. © 2024, The Authors. All rights reserved.

Metal-organic frameworks (MOFs) have emerged as a key focus in water treatment and monitoring due to their unique structural features, including extensive surface area, customizable porosity, reversible adsorption, and high catalytic efficiency. While numerous reviews have discussed MOFs in environmental remediation, this review specifically addresses recent advancements in modifying MOFs to enhance their effectiveness in water purification and monitoring. It underscores their roles as adsorbents, photocatalysts, and in luminescent and electrochemical sensing. Advancements such as pore modification, defect engineering, and functionalization, combined synergistically with advanced materials, have led to the development of recyclable MOF-based nano-adsorbents, Z-scheme photocatalytic systems, nanocomposites, and hybrid materials. These innovations have broadened the spectrum of removable contaminants and improved material recyclability. Additionally, this review delves into the creation of multifunctional MOF materials, the development of robust MOF variants, and the simplification of synthesis methods, marking significant progress in MOF sensor technology. Furthermore, the review addresses current challenges in this field and proposes potential future research directions and practical applications. The growing research interest in MOFs underscores the need for an updated synthesis of knowledge in this area, focusing on both current challenges and future opportunities in water remediation. © 2024 Elsevier Ltd

Microplastics (MPs) and nanoplastics (NPs) have gained increasing attention in environmental research due to their ubiquitousness and potential impacts on natural environments and human health as per the UN Sustainable development Goals (SDGs), particularly SDG-14 to address global threats where at least 12 SDGs, directly/indirectly impacts. Present review is undertaken to highlight the process of breakdown of diverse groups of plastic products in soil, surface water, and groundwater under the influence of different factors (UV, light, heat, microbe, etc.), which are mobilized as MPs/NPs to the surface water, groundwater, air, soil, and living organisms by different natural and anthropogenic processes. Review also highlights a comprehensive overview of the methodology for sampling, characterization, and analysis for these minuscule plastic particles (PPs) in various environmental samples, encompassing surface/subsurface water, sediments, soils, and biological organisms. The collection, extraction, and characterization of MPs/NPs, typically employ filtration processes, wherein a known volume of water is passed through a fine mesh to capture MPs/NPs from water samples. Sediment/soil samples require sieving and density separation techniques to isolate PPs from the surrounding matrix. Biological samples require digestion steps to remove organic matter, leaving behind plastics for analysis. Fourier-transform infrared (FTIR) spectroscopy, Raman spectroscopy, and scanning electron microscopy (SEM) are commonly utilized to determine the polymer composition, size, shape, and surface characteristics of PPs. Quantification involves several approaches, visual counting, image analysis, and spectroscopic techniques. Abundance of MPs/NPs in the respective environmental samples (water, air, soil, etc.) can be determined by comparing the richness (i.e., number/mass) of plastics to the volume or weight of the original sample. Such comprehensive analytical methodologies contribute to

Conventional water treatment processes often fail to effectively remove antibacterial drugs, necessitating advanced strategies. This study presents the synthesis of novel floating, visible light-active α-NiMoO4/mpg-C3N4/EP composites for the removal of ciprofloxacin (CFX), a widely used quinolone antibiotic, from water. These composites are easily recoverable, highly stable, and demonstrate excellent reusability. The optimal photocatalyst, NC-101/EP (α-NiMoO4/mpg-C3N4 = 10:1), achieved 96.2 ± 1.1% degradation of CFX at 1.6 g L−1 within 80 min under visible light, significantly outperforming previous benchmarks. This high efficiency is attributed to the formation of interfacial junctions and a built-in electric field, which enhanced charge transfer and hydroxyl radical generation through an S-scheme mechanism. Fluorescence spectroscopy provided precise monitoring of CFX degradation without interference from coexisting intermediates. Density functional theory (DFT) calculations revealed that hydroxyl radicals initiated highly favorable and spontaneous oxidation of CFX, with a reaction rate constant of 6.04 × 109 M−1 s−1. The preferred oxidation pathway followed the sequence: HO-addition > H-abstraction > single electron transfer. Four degradation pathways were identified, with key intermediates confirmed by high-resolution mass spectrometry. The process also significantly reduced CFX toxicity, ensuring minimal environmental impact. These findings position NC-101/EP as a promising photocatalyst for large-scale water treatment applications targeting antibiotic contamination. © 2024 Elsevier Ltd

Inertial Measurement Unit to Segment Calibration Based on Physically Constrained Pose Generation

Ltd. Fukuroi Engineering Center Japan

The accuracy of a motion capture (MoCap) system based on inertial measurement units (IMUs) depends on the IMU-to-segment (I2S) calibration, in which the IMU alignment relative to a body segment is calculated using a reference pose such as a standing T-pose. This study proposes a novel I2S calibration system for a reliable MoCap system. In this system, the reference pose for calibration is constrained by physical objects, and this pose is generated by an optimization-based method which incorporates the IMU measurements with the physical constraints between the body and the object. To demonstrate the system, we estimated the chair-sitting and half-squat motions based on the calibration using a chair and estimated the center-of-mass movements of a rider when riding a motorcycle based on the calibration using a motorcycle. The experiments confirmed the improvements of the motion estimation accuracy by the proposed system, in both chair-sitting and half-squat motion and center-of-mass tracking of a rider. Furthermore, the proposed system enables the I2S calibration using product-use poses. © Taylor & Francis group, LLC 2020.

Drugs and other substances with psychoactive substances have the potential to alter body functioning and structure when ingested either for medical or recreational purposes. The study investigated the effects of ethanol with Nicotiana tabacum and Cannabis sativa on markers of brain function and hematological parameters through both an experimental and docking predictive approach. Thirty-five female Wistar rats with an average weight of 180 ± 0.5 g were randomly assigned to seven treatment groups of five rats each: ethanol, Nicotiana tabacum, Cannabis sativa, ethanol + Nicotiana tabacum, ethanol + Cannabis sativa, and ethanol + Nicotiana tabacum + Cannabis sativa. The dosage of the substance administered in each group includes 30 ml/kg body weight (BW) of 40% ethanol, 13.44 g/kg BW of Nicotiana tabacum, and 6.72 g/kg BW of Cannabis sativa. Smoke from Nicotiana tabacum and Cannabis sativa sativa was inhaled for five minutes while ethanol was given orally. At the end of the 28-day treatment, the rats were euthanized. Brain homogenates underwent biochemical assays and blood parameters were examined. There was a significant decrease (p<0.05) in malondialdehyde (MDA) concentration in the ethanol group in comparison to the treated groups and the control group. On the contrary, the groups exposed to Nicotiana tabacum and Cannabis sativa smoke, as well as the control group showed a significant increase (p<0.05) in total protein concentration compared to the ethanol group. There was a significant decrease (p<0.05) in catalase activity in the ethanol group compared to the treated groups and the control group. Furthermore, there was a significant increase (p<0.05) in HGB and RDW in groups exposed to Nicotiana tabacum and Cannabis sativa smoke respectively, and in the control group in comparison to the ethanol group. When compared to ethanol and nicotine, delt-9-tetrahydrocannabinol had the highest binding energy across receptor proteins. Ethanol, nicotine, and delt-9- tetrahydr
