Published: March 2023

AbstractIn this study, composites of HKUST‐1 MOF with nanocellulose, HKUST‐1@NCs, have been prepared and explored for CO2/N2 gas‐separation and dye‐sorption based applications. Our biopolymer‐MOF composites are prepared via a copper ion pre‐seeding method, in which, the HKUST‐1 crystallites are grown in situ on the Cu‐seeded and carboxylate anchored NC fibers for a better interfacial integration between the MOF and the polymer matrices. Static gas sorption studies show the capability of one of our HKUST‐1@NC composites to reach ∼300 % enhancement in the CO2/N2 sorption selectivity compared to the corresponding MOF alone ‐ blank reference sample prepared at similar conditions. The same composite, C100, in the bulk powder form, shows a remarkable IAST sorption selectivity of 298 (CO2/N2) at 298 K and 1 bar for the CO2/N2 (15/85, v/v) gas mixture. The relative position of the C100, in the bound plot visualizations of the CO2/N2 separation trade‐off factors indicate a significant potential. The HKUST‐1@NC composites have also been processed along with a polymeric cellulose acetate (CA) matrix as HKUST‐1@NC@CA films to study them as free‐standing mixed‐matrix membranes. The CO2/N2 sorption selectivity, at 298 K and 1 bar is 600 for one such membrane, C‐120@CA, as bulk sample studied by the static gas sorption. The composite, C120, exhibits a good uptake with an enhancement of 11 % for alizarin and 70 % for Congo red in comparison to the uptakes of the corresponding blank reference HKUST‐1 sample, B120.
Tailoring the Reactor Properties in the Small‐Scale Sorption‐Enhanced Methanol Synthesis
Authors: Moioli Emanuele , Schildhauer Tilman 
Published: March 2023

AbstractThe performance of a fixed‐bed and entrained flow reactor for the sorption‐enhanced methanol synthesis from CO2 is assessed by modelling. Both reactors achieve good performance but show possible drawbacks. The fixed bed reactor requires several units working in parallel, while the entrained flow reactor needs a large volume due to the high superficial particle velocity. We propose a new reactor type, which combines a circulating sorbent with a fluidized bed methanol catalyst in bubbling regime. This solution achieves high CO2 conversion with high space velocity in a continuous manner.

AbstractA series of poly[methyl(trifluoropropyl)siloxane‐co‐silphenylenesiloxane] (PMTFPS‐co‐SPS) was synthesized by condensation polymerization of methyltrifluoro‐propylsiloxanediol and 1,4‐bis(dimethylsilyl)benzene. Their chemical structures were investigated using gel permeation chromatography (GPC), Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR), and dynamic thermomechanical analysis (DMA). The effect of silphenylenesiloxane (SPS) units on the thermal stability of poly[methyl(trifluoropropyl)siloxane] (PMTFPS) was studied by thermogravimetric analysis (TGA), isothermal degradation tests, quantum chemical calculation, and pyrolysis‐gas chromatography–mass spectrometry (Py‐GCMS). The results showed that the thermal stability of PMTFPS improved with the introduction of SPS units into the backbone. The temperature for 5% mass loss in PMTFPS increased by 63°C under a nitrogen atmosphere. Additionally, the mechanism by which the SPS units improve the thermal stability of PMTFPS was also investigated.

Published: March 2023

Comprehensive SummaryMetal clusters with photoswitching ligands can undergo magnetic changes under light radiation, which makes them potential optical‐response magnetic‐switching materials. Herein, a photoswitchable Mn‐oxo cluster [MnII15MnIII4(L)18(OH)12(N3)6] (ClO4)2 (C6H5CN)8, (Mn19azo, HL=1‐(hydroxymethyl)‐3,5‐dimethyl‐4‐(phenyldiazenyl)‐pyrazole) has been designed and synthesized to realize the photoswitching behavior. Mn19azo shows quick trans‐to‐cis transformation upon 365 nm light irradiation in CH2Cl2 solution and solid state as confirmed by UV‐Vis spectra. After the powder sample was irradiated for 80 min, the Curie constant of Mn19azo increases by about 7%. The change of magnetic properties can be considered as the result of the change of intermolecular interactions.
Penalized complexity priors for the skewness parameter of power links

Published: March 2023

AbstractThe choice of a prior distribution is a key aspect of the Bayesian method. However, in many cases, such as the family of power links, this is not trivial. In this article, we introduce a penalized complexity prior (PC prior) of the skewness parameter for this family, which is useful for dealing with imbalanced data. We derive a general expression for this density and show its usefulness for some particular cases such as the power logit and the power probit links. A simulation study and a real data application are used to assess the efficiency of the introduced densities in comparison with the Gaussian and uniform priors. Results show improvement in point and credible interval estimation for the considered models when using the PC prior in comparison to other well‐known standard priors.

AbstractIntroductionPlasma neurofilament light chain (NfL) is a potential biomarker for neurodegeneration in Alzheimer's disease (AD), ischemic stroke, and non‐dementia cohorts with cerebral small vessel disease (CSVD). However, studies of AD in populations with high prevalence of concomitant CSVD to evaluate associations of brain atrophy, CSVD, and amyloid beta (Aβ) burden on plasma NfL are lacking.MethodsAssociations were tested between plasma NfL and brain Aβ, medial temporal lobe atrophy (MTA) as well as neuroimaging features of CSVD, including white matter hyperintensities (WMH), lacunes, and cerebral microbleeds.ResultsWe found that participants with either MTA (defined as MTA score ≥2; neurodegeneration [N]+WMH−) or WMH (cut‐off for log‐transformed WMH volume at 50th percentile; N−WMH+) manifested increased plasma NfL levels. Participants with both pathologies (N+WMH+) showed the highest NfL compared to N+WMH−, N−WMH+, and N−WMH− individuals.DiscussionPlasma NfL has potential utility in stratifying individual and combined contributions of AD pathology and CSVD to cognitive impairment.

AbstractObjectivesEndoscopic submucosal dissection (ESD) is effective for the resection of colorectal intramucosal lesions. This study was performed to examine the safety and effectiveness of using dexmedetomidine (DEX) in the anesthesia regimen of patients with colorectal lesions undergoing ESD.MethodsWe retrospectively examined 287 consecutive patients who underwent ESD for colorectal lesions in our institution from January 2015 to December 2021. Outcomes including the frequency of intraprocedural pain and adverse events were compared between the DEX and no DEX groups. Moreover, univariate and multivariate analyses were conducted for each clinical factor of intraprocedural pain. Intraprocedural pain was defined as patient‐reported abdominal pain or body movement during the procedure.ResultsThe incidence of intraprocedural pain was significantly lower in the DEX than in the no DEX group (7% vs. 17%, p = 0.02). The incidence of hypotension was also significantly higher in the DEX group (7% vs. 0%, p = 0.01), but no cerebrovascular or cardiac ischemic events occurred. In the univariate analyses, the diameter of the resected specimen, procedure time, no use of DEX, and total midazolam dose was associated with intraprocedural pain. The midazolam dose and DEX administration were significantly negatively correlated and the diameter of resected specimen and procedure time were significantly positively correlated. Multivariate logistic regression showed that no use of DEX was independently associated with intraprocedural pain (p = 0.02).ConclusionsAdding DEX to the anesthesia regimen in patients undergoing colorectal ESD appears to be safe and effective for reducing intraprocedural pain.

AbstractEcuador has both high richness and high endemism, which are increasingly threatened by anthropic pressures, including roads. Research evaluating the effects of roads remains scarce, making it difficult to develop mitigation plans. Here, we present the first national assessment of wildlife mortality on roads that allow us to (1) estimate roadkill rates per species, (2) identify affected species and areas, and (3) reveal knowledge gaps. We bring together data from systematic surveys and citizen science efforts to present a dataset with 5010 wildlife roadkill records from 392 species, and we also provide 333 standardized corrected roadkill rates calculated on 242 species. Systematic surveys were reported by ten studies from five Ecuadorian provinces, revealing 242 species with corrected roadkill rates ranging from 0.03 to 171.72 ind./km/year. The highest rates were for the yellow warbler Setophaga petechia in Galapagos (171.72 ind./km/year), the cane toad Rhinella marina in Manabi (110.70 ind./km/year), and the Galapagos lava lizard Microlophus albemarlensis (47.17 ind./km/year). Citizen science and other nonsystematic monitoring provided 1705 roadkill records representing all 24 provinces in Ecuador and 262 identified species. The common opossum Didelphis marsupialis, the Andean white‐eared opossum Didelphis pernigra, and the yellow warbler Setophaga petechia were more commonly reported (250, 104, and 81 individuals, respectively). Across all sources, we found 15 species listed as “Threatened” and six as “Data Deficient” by the IUCN. We recommend stronger research efforts in areas where the mortality of endemic or threatened species could be critical for populations, such as in Galapagos. This first country‐wide assessment of wildlife mortality on Ecuadorian roads represents contributions from academia, members of the public, and government, underlining the value of wider engagement and collaboration. We hope these findings and the compiled dataset will guide sensible driving and sustainable planning of infrastructure in Ecuador and, ultimately, contribute to reduce wildlife mortality on roads.

AbstractIn May 2021, we opportunistically observed one Eurasian jay (Garrulus glandarius) attacking an adult incubating Japanese tit (Parus minor) and depredating nine tit eggs at a nest box where a woodpecker had greatly enlarged the entrance. After the predation event, the Japanese tits abandoned the nest. We recommend that when using artificial nest boxes to protect hole‐nesting birds, the appropriate entrance size should be proportional to the body size of the target species. This observation gives us a better understanding of the potential predators of secondary hole‐nesting birds.

AbstractWith the booming of automobiles industry, the recycling of automobile shredder residue (ASR) with complicated constitutes gradually become an urgent issues owing to its difficulty for traditional recycling. Herein, solid‐state shear milling (S3M) technology which can control the domain size of the various polymers in blend was applied to overcome the mismatch of viscosity and poor compatibility of ASR and thus modify the processability to match practical manufacturing. Resultantly, the melt processing of ASR was achieved and a high‐density polyethylene (HDPE)/ASR composite was also prepared with more optimal mechanical properties (tensile strength: 53.2 MPa, impact strength: 36.9 kJ/m2), compared with commercially available recycled PE. This work not only provided a feasible application route for the recycling of ASR material, but also demonstrated the optional methodology for recycling polymer waste with complicated component via physical recycling way.
Convoluted filtering for process cycle modeling
Authors: Romanov Vyacheslav 
Published: March 2023

AbstractPrinciples of materials science and engineering, physics, mathematics, and information science are used to extract knowledge and insights from the process‐structure–property‐performance relationships hidden in materials data. The process‐structure modeling can be accelerated without loss of interpretability, with artificial intelligence tools that mimic the salient features of the process and process‐structure relations. In this work, a novel convoluted model‐filtering technique was exploited to build and successfully train the Convoluted Filter (CoFi) artifacts for Fe‐based alloy heat treatment cycles. The artifacts were pre‐trained to filter out deep models that change the surrogate microstructure state after the heat treatment at ambient conditions. Direct representation of the thermal cycle features within knowledge Graph facilitated development of meaningful data models for microstructure evolution, which reduce overfitting to limited datasets.

Published: March 2023

AbstractTiN nanoparticles based plasmonic nanofluids exhibit promising results in performance improvement of direct absorption solar collectors, but the main issue for practical application is their poor stability. In this work, ethylene glycol (EG) based TiN nanofluids with polyacrylic acid (PAA) stabilizing ligand were prepared. The optical properties of the TiN‐PAA/EG nanofluids with concentration ranging from 10 to 100 mg/L were characterized. The solar weighted absorption fraction of 99.55% is achieved at the optical depth of 1 cm when the concentration of the TiN‐PAA/EG nanofluids is 100 mg/L. In addition, the experimental results of the long‐term stability indicated that the TiN‐PAA/EG nanofluid retained excellent dispersion stability after ambient storage of 250 days. Then, the stability of TiN‐PAA/EG nanofluids upon prolonged heating cycle and accelerated ultraviolet (UV) irradiation was investigated. The results showed that TiN‐PAA/EG nanofluid with concentration of 75 mg/L presents superior thermal stability after prolonged heating cycles at 120°C and excellent photostability after 30 days of UV irradiation. Finally, the photo‐thermal conversion performance for TiN‐PAA/EG nanofluids was studied. The stagnation temperature of the 100 mg/L TiN‐PAA/EG nanofluids after light irradiation of 2 h reaches up to 80.12°C. The specific absorption rate of the prepared TiN‐PAA nanofluids is demonstrated higher than that of reported TiN nanofluids.

Published: March 2023

AbstractFor the purpose of low‐medium air heating applications like timber seasoning, HVAC, agricultural & food drying, space heating and desalination, there is requirement of hot air. Solar air heaters are the promising systems to satisfy these requirements in a very inexpensive manner. Due to higher efficiency at higher operating temperature and lower cost, evacuated tube collectors (ETCs) are preferred for solar air heating. In this manuscript, the comparative parametric study of two similar sets of evacuated tube solar air heater (ETSAH) is performed. The comparison is based on energy & exergy analyses, and also presents the environmental and economic study (4E analyses). Each set is fabricated using mild steel (M.S.) along with 50 evacuated tubes with total collector area of 8.46 m2. The experimental investigations are made at diverse flow rates, with and without using conventional reflectors. Without incorporating any additional heat storage unit, the system provides average hot air temperature of 76.13°C when average solar intensity was 502.68 W/m2 during 11 h of operation from 09:00 to 20:00 h. ETC's absorber glass and the M.S. material was observed to have significant energy storage and discharge. The single set of ETSAH has mitigation of 89.20 tons with 2.05 years of energy payback period, which is significantly low as compared to its 20 years of lifespan. For the optimum system performance the cost of generated hot air is 0.00048 $/kg, which is considerably low.

AbstractThe green electrochemical synthesis of ammonia (NH3) through solid electrolysis has been intensively investigated. This research reported an improvement of NH3 production rate using in situ exsolution of ruthenium (Ru) atoms into lanthanum strontium chromium ferrite perovskite (LaxSr1−xCryFe1−yO3−δ) catalyst. The in situ Ru exsolution was achieved by reducing the optimized stoichiometric La0.33Sr0.67Cr0.33Fe0.52Ru0.15O3−δ (LSCrFRu) powders obtained in 10‐vol% H2/Ar at 800°C for 1.0 h. These Ru nanoparticles (NPs) were embedded on the surface of the LSCrFRu matrix, evenly distributed with a size varying from 4.4 ± 0.5 nm. With the exsolution of Ru atoms, greater oxygen vacancies were formed in ex‐LSCrFRu and gadolinium‐doped ceria (GDC) composite than those in LSCrF‐GDC electrocatalyst, beneficial to N2 gas adsorption and triple bond cleavage. These Ru‐modified LSCrFRu‐GDC catalysts showed a synthesis rate of 4.73 × 10−10 mol s−1 cm−2 at 550°C under 1.6 V, doubling the rate using LSCrF‐GDC catalyst. The improved ammonia synthesis kinetic is mainly attributed to embedded Ru NPs and the increased oxygen vacancies formed during the in situ exsolution process. More active sites and higher activity for H2O and N2 adsorption and activation collectively advanced facile transportation of O2− that further promotes the cleavage of covalent bonds in H2O, providing more H+ for the hydrogenation in the nitrogen reduction reaction. This research will open a new paradigm for the electrochemical synthesis of ammonia with mitigating the drawbacks of traditional NH3 production.

Published: March 2023

AbstractOctopuses (scientific order Octopoda under the scientific class Cephalopoda) are a group of aquatic species with economic importance as a food product in many countries around the world. Octopus products are consumed in many different geographic locations around the world, including East Asia, the Mediterranean region, the Caribbean region, and South American coastal regions. To‐date, a comprehensive scientific review of octopus with direction toward procurement, food processing, and food quality has not been published. The purpose of this review was to provide a practical overview of the nomenclature, procurement (i.e., catching), processing, quality, and shelf‐life of octopus. The objective was accomplished by strategically searching for scientific literature on the topic of octopus and octopus‐derived food products. Octopus‐derived food products have a high protein content (70%–85% on a dry matter basis), significant levels of important major and trace minerals, and significant levels of essential vitamins. In addition, octopus‐derived food products are highly sought after in some areas of the world. However, recognized standards for procurement of octopus and preparation of octopus‐derived food products vary around the world and are frankly inconsistent and under reported. The octopus industry would greatly benefit from greater levels of practical information becoming available, especially as the industry experiences growth and heightened levels of demand.
The causal mechanisms underlying analogical reasoning performance improvement by executive attention intervention
Authors: Lin Yixuan , Li Qing , Chen Antao 
Published: March 2023

AbstractAnalogical reasoning is important for human. We have found that a short executive attention intervention improved analogical reasoning performance in healthy young adults. Nevertheless, previous electrophysiological evidence was limited for comprehensively characterizing the neural mechanisms underlying the improvement. And although we hypothesized that the intervention improved active inhibitory control and attention shift first and then relation integration, it is still unclear whether there are two sequential cognitive neural activities were indeed changed during analogical reasoning. In the present study, we combined hypothesis with multivariate pattern analysis (MVPA) to explore the effects of the intervention on electrophysiology. Results showed that in the resting state after the intervention, alpha and high gamma power and the functional connectivity between the anterior and middle in the alpha band could discriminate the experimental group from the active control group, respectively. These indicated that the intervention influenced the activity of multiple bands and the interaction of frontal and parietal regions. In the analogical reasoning, alpha, theta, and gamma activities could also fulfill such discrimination, and furthermore, they were sequential (alpha first, theta, and gamma later). These results directly supported our previous hypothesis. The present study deepens our understanding about how executive attention contributes to higher‐order cognition.
