AbstractIn this study, structural, electronic, optical, thermoelectric, and thermodynamics properties of vacancy‐ordered double perovskites Rb2XCl6 (X = Se, Ti) were explored theoretically. The results revealed that Rb2SeCl6 and Rb2TiCl6 are indirect band gap (Eg) semiconductors with Eg values of 2.95 eV, and 2.84 eV respectively. The calculated properties (phonons, elastic constant, Poisson's ratio, and Pugh's ratio) revealed that both materials are dynamically and chemically stable and can exhibit brittle (Rb2SeCl6) and ductile (Rb2TiCl6) nature. From the analysis of optical parameters, it was noticed that the refractive index of the materials has a value of 1.5–2.0 where light absorption was found from the visible to the ultraviolet region. The thermoelectric properties determined by using the BoltzTrap code demonstrated that at room temperature, the Figure of merit (ZT) was found to be 0.74 and 0.76 for Rb2SeCl6 and Rb2TiCl6, respectively. Despite a moderate value of ZT in such materials, further studies might explore effective methods for tuning the electronic band gap and improving the thermoelectric response of the material for practical energy production applications.

AbstractBACKGROUNDDuring the past several decades, photocatalytic activity by ferrite nanomaterials has been widely interested in environmental remediation. Magnetically recyclable CuFe2O4/rGO nanocomposite with different graphene oxide contents was prepared by hydrothermal method, and the photodegradation performance of this nanocomposite was studied under sunlight irradiation.RESULTSThe magnetic property of the nanocomposite showed a high magnetic saturation with super‐paramagnetic nature, leading to an additional use for catalysts aside from pollutant suspension and recyclable. The experimental results showed that the CuFe2O4/rGO (10 wt.%) nanocomposite had the best photocatalytic activity in tetracycline (TC) degradation, and its photocatalytic degradation rate was 1.55 and 1.85 times higher than those of CuFe2O4/rGO15 and CuFe2O4/rGO20 under sunlight irradiation in 160 min.CONCLUSIONSThis considerable enhancement in performance was mainly due to the formation of the CuFe2O4/rGO nanocomposite, which promoted effective charge carrier separation and delayed the recombination process. The possible photodegradation mechanism of the nanocomposite was revealed based on the energy levels and active radical scavenger experiments. The superoxide radical was the main reaction species, thus confirming the TC degradation mechanism. The enhanced photocatalytic performance of CuFe2O4/rGO nanocomposite has attracted attention for its use as a potential candidate for the degradation of organic pollutants.

Effects of endophytic Bacillus spp. on accumulation and distribution of iron in the shoots of lowland rice grown under iron toxic conditions
Authors: Weinand Tanja , Asch Julia , Asch Folkard 
Published: April 2023

AbstractBackgroundThe tolerance of plants against abiotic stresses can be greatly influenced by their interaction with microbes. In lowland rice (Oryza sativa) production, the iron toxicity of the soils constitutes a major constraint. Although there are tolerant cultivars, the mechanisms underlying the tolerance against excess iron are not fully understood. Even less is known about the role of microbes in the response to iron toxicity.AimIn the study presented here, the effects of different Bacillus isolates on the accumulation and distribution of iron within the shoots of different rice cultivars grown under iron toxicity were analyzed.MethodsThree lowland rice cultivars with contrasting tolerance to iron toxicity (IR31785‐58‐1‐2‐3‐3, Sahel 108, Suakoko 8) were inoculated with three Bacillus isolates (two B. pumilus and one B. megaterium) and, after 1 week, exposed to excess iron (1,000 ppm) for 8 days. Tolerance was evaluated by leaf symptom scoring.ResultsBacterial inoculation mitigated leaf symptoms in the sensitive cultivar IR31785‐58‐1‐2‐3‐3 despite no significant differences in shoot iron concentration between inoculated and noninoculated plants. In the tolerant excluder cultivar, Suakoko 8, leaf symptoms were exacerbated when inoculated with B. pumilus Ni9MO12. While the total shoot Fe concentration was not affected in this bacteria × cultivar combination, the distribution of iron within the shoot was clearly disturbed. Tolerance to iron toxicity of the tolerant includer cultivar, Sahel 108, was not affected by Bacillus inoculation.ConclusionIn conclusion, our results show that Bacillus inoculation can affect the tolerance of lowland rice to iron toxicity and that the effects strongly depend on the bacteria × cultivar combination.

Published: April 2023

Bulk and precipitation polymerization methods were used to prepare ibuprofen‐molecularly imprinted polymers. Molecularly imprinted polymer‐bulk and ‐precipitation were synthesized in acetonitrile, likewise molecularly imprinted polymer‐bulk (mixture) and molecularly imprinted polymer‐precipitation (mixture) in a mixture of acetonitrile/toluene (75:25 v/v). N2 adsorption‐desorption analysis data revealed that molecularly imprinted polymer‐precipitation (mixture) has the highest specific surface area (200.74 m2/g). The surface chemistry and morphology of the synthesized sorbents were investigated by Fourier‐transform infrared analysis and scanning electron microscope micrographs respectively. The prepared sorbents in the mixture of solvents were used in a dispersive solid‐phase extraction process for selective extraction and pre‐concentration of ibuprofen from urine and human plasma samples. The detection limits were 62.91 and 7.89 ng/ml using molecularly imprinted polymer‐bulk (mixture) and molecularly imprinted polymer‐precipitation (mixture), respectively. Also, the sorbents showed selective behavior to extract ibuprofen in the presence of naproxen, fenoprofen, and ketoprofen. Overall, the results showed that the precipitation method in the mixture of acetonitrile/toluene resulted in the preparation of a sorbent with the highest extraction efficiency. Furthermore, a pharmacokinetic study was done. The maximum plasma concentration, the time required for maximum plasma concentration, and plasma half‐life were 28.95 μg/ml, 2, and 2.39 h, respectively.

AbstractBulk density, porosity, and water retention capacity play a key role in limiting root growth and nutrient uptake in developed technogenic soils. Thus, the purpose of this study was to evaluate the impact of reclamation technologies and different vegetation types on vital physical soil properties formed from carboniferous materials. The case study was conducted on Sośnica hard coal post‐mine spoil heaps (Upper Silesian Coal Basin of Southern Poland). Nine experimental combinations of reclamation technologies and vegetation types were tested. For vegetation types and basic physical soil parameters, 120 plots (10 × 10 m) were selected. The texture analysis was done on composite soil samples collected at two uppermost soil depths (0–10 and 10–20 cm). Intact structure samples were collected into 100cm3 cylinders from the middle of each plot at both depths for bulk density (BD), porosity, capillary water capacity (CWC), and soil water storage (SWS). In the comparison of different reclamation scenarios, we noted that topsoiling increased BD, whereas CWC and porosity decreased. Spontaneous succession had the same effect on BD, porosity, and CWC as cultivation. Revegetation of the spoil heap with grasses and forbs resulted in lower BD and higher porosity and CWC in the top layer (0–10 cm), whereas woodland resulted in lower BD and higher porosity and CWC at lower depths (10–20 cm). The decreasing order of the SWS was grassland > forbland > woodland. Thus, forbs and grasses should be followed by tree planting, which is crucial to improving the hostile physical properties of the Carboniferous postmine soils.

Published: April 2023

AbstractDucted fans with thin‐shelled tubular structures are typically used in unmanned aerial vehicles. However, due to their thinness and heterogeneity, the ducts are prone to warpage deformation, which can adversely affect the aerodynamic characteristics of the fans. In this study, Moldflow software was used to analyze and reduce the warpage deformation of a duct made of 15 wt% glass fiber‐reinforced acrylonitrile butadiene styrene. First, a Taguchi experiment was performed to determine the main factors affecting the warpage: the mold surface temperature, melt temperature, injection pressure, and holding pressure. Subsequently, the response surface methodology (RSM) was employed to define a regression equation and response surface relating the dependent and independent variables, and a genetic algorithm (GA) was used for optimization. The maximum warpage was successfully reduced from 0.2217 to 0.0465 and 0.0578 mm through the RSM and GA analyzes, respectively, and the simulated results were validated by data collected using a COMET L3D system. Finally, the influence of the warpage of the ducted rear deflector on the aerodynamic performance was investigated by performing computational fluid dynamics analysis. The results indicated that curving the rear deflector has a beneficial effect on aerodynamic performance, as it increases velocity, but it also reduces the impact of the torque balance. This paper describes an innovative application method using a specific combination of analysis tools to address the problem of optimizing the design, modeling, and performance of ducted fans. This work can help predict manufacturing results and aerodynamic effectiveness at an early stage.
Improved electrical actuation and dielectric strength of rubber composites with polydopamine noncovalent and silane covalent modification of carbon nanotube
Authors: Lu Huiwan , Yang Dan 
Published: April 2023

AbstractA dielectric elastomer actuator (DEA) is regarded as an intelligent actuator that can reproduce the performance of human muscle. A core–shell structured dielectric filler is synthesized by modifying carbon nanotube (CNT) with polydopamine (PDA) noncovalently and 3‐mercaptopropyl ethyoxyldi (tridecyl‐pentaethoxy) silane (Si747) covalently, designated as PDA‐Si747@CNT. Then, the filler is incorporated into an epoxy natural rubber (ENR) matrix to yield dielectric elastomer composites, denoted as PDA‐Si747@CNT/ENR. The PDA and Si747 modifications improve not only the filler dispersion but also the dielectric strength of the ENR composites. More importantly, Si747 is involved in vulcanization and provides chemical bonds between CNT and ENR chains. The maximum actuated strain of the PDA‐Si747@CNT/ENR composites increases to 17.9% at 55.5 kV mm−1, which is 152% higher than that of CNT/ENR composites (7.1% at 30 kV mm−1). Furthermore, the ENR composite‐based DEA demonstrates excellent stability and reliability, which is advantageous for practical applications. © 2023 Society of Industrial Chemistry.

Published: April 2023

AbstractPlant growth‐promoting bacteria (PGPB) may be of use for increasing crop yield and plant resilience to biotic and abiotic stressors. Using hyperspectral reflectance data to assess growth‐related traits may shed light on the underlying genetics as such data can help assess biochemical and physiological traits. This study aimed to integrate hyperspectral reflectance data with genome‐wide association analyses to examine maize growth‐related traits under PGPB inoculation. A total of 360 inbred maize lines with 13,826 single nucleotide polymorphisms (SNPs) were evaluated with and without PGPB inoculation; 150 hyperspectral wavelength reflectances at 386–1021 nm and 131 hyperspectral indices were used in the analysis. Plant height, stalk diameter, and shoot dry mass were measured manually. Overall, hyperspectral signatures produced similar or higher genomic heritability estimates than those of manually measured phenotypes, and they were genetically correlated with manually measured phenotypes. Furthermore, several hyperspectral reflectance values and spectral indices were identified by genome‐wide association analysis as potential markers for growth‐related traits under PGPB inoculation. Eight SNPs were detected, which were commonly associated with manually measured and hyperspectral phenotypes. Different genomic regions were found for plant growth and hyperspectral phenotypes between with and without PGPB inoculation. Moreover, the hyperspectral phenotypes were associated with genes previously reported as candidates for nitrogen uptake efficiency, tolerance to abiotic stressors, and kernel size. In addition, a Shiny web application was developed to explore multiphenotype genome‐wide association results interactively. Taken together, our results demonstrate the usefulness of hyperspectral‐based phenotyping for studying maize growth‐related traits in response to PGPB inoculation.

AbstractObjectivesTo reduce cancer care disparities in people with mental illness, this study aimed to quantify psychiatric care providers' perceptions regarding issues that are insufficiently addressed or difficult to address.MethodsPsychiatric care providers at 23 psychiatric hospitals in Japan were surveyed using mail questionnaires. Respondents were asked to rate 15 items with four categories related to insufficiencies/difficulties in cancer care for patients with mental illness on a five‐point Likert scale. We analyzed the proportion of respondents who answered “insufficient/difficult” for each item.ResultsA total of 255 (76.3%) psychiatric care providers responded. For questions related to the skills and attitudes of psychiatric professionals, 48.3%–58.4% of respondents perceived that efforts for supporting cancer screening and treatment were insufficient. For the questions related to collaborations between cancer and psychiatric care providers, 75.3% of respondents perceived that inpatient visits between psychiatric and cancer hospitals were insufficient. For the questions related to in‐psychiatric‐hospital medical systems, 50.2%–87.2% of respondents perceived that support for screening, diagnosis/treatment, and palliative care for psychiatric inpatients were insufficient/difficult. 41.9%–57.4% of respondents perceived that social services in the community were insufficient.ConclusionsThis study clarified the level of insufficiency/difficulty perceived by psychiatric care providers regarding issues related to cancer care for people with mental illness. Psychiatric care providers are required to have knowledge and skills in cancer screening and treatment. To improve access to cancer prevention, treatment, and palliative care, it may be helpful to establish systems to promote coordination between cancer hospitals and psychiatric hospitals.

AbstractBackgroundPrimary ciliary dyskinesia (PCD) is typically an autosomal recessive disease characterized by recurrent infections of the lower respiratory tract, frequent and severe otitis media, chronic rhinosinusitis, neonatal respiratory distress, and organ laterality defects. While severe lower respiratory tract infections and bronchiectasis are common in Inuit, PCD has not been recognized in this population.MethodsWe report a case series of seven Inuit patients with PCD identified by genetic testing in three Canadian PCD centers.ResultsPatients ranged from 4 to 59 years of age (at time of last evaluation) and originated in the Qikiqtaaluk region (Baffin Island, n = 5), Nunavut, or Nunavik (northern Quebec, n = 2), Canada. They had typical features of PCD, including neonatal respiratory distress (five patients), situs inversus totalis (four patients), bronchiectasis (four patients), chronic atelectasis (six patients), and chronic otitis media (six patients). Most had chronic rhinitis. Genetic evaluation demonstrated that all had homozygous pathogenic variants in DNAH11 at NM_001277115.1:c.4095+2C>A.ConclusionsThe discovery of this homozygous DNAH11 variant in widely disparate parts of the Nunangat (Inuit homelands) suggests this is a founder mutation that may be widespread in Inuit. Thus, PCD may be an important cause of chronic lung, sinus, and middle ear disease in this population. Inuit with chronic lung disease, including bronchiectasis or laterality defects, should undergo genetic testing for PCD. Consideration of including PCD genetic analysis in routine newborn screening should be considered in Inuit regions.
