Published: March 2022

AbstractMetallic zinc (Zn) having low cost, high capacity, environmentally friendly features is considered to be an attractive anode material for aqueous energy storage devices. However, dendritic growth and severe side reactions restrict the development of Zn‐metal anodes. Numerous 3D hosts are extensively explored to settle these issues, whereas the accessible prestoring of Zn metal into structured electrodes is challenging. Here, a thermal infusion strategy is first reported to create a stable composite Zn‐based anode. Upon this melting–wetting–cooling process, the metallic Zn is densely and firmly encapsulated in the 3D skeleton, efficiently inhibiting the dendritic growth. Meanwhile, through in/ex situ tests, the formation of ZnO layer on the metallic Zn surface inhibits the hydrogen evolution reactions (1.8 mmol h−1 cm−2) and passivation during cycling. Consequently, the electrode enables a long‐cycling life of over 1000 cycles at 10 mA cm−2 in a symmetrical cell. The pouch cells pairing this novel anode and LiMn2O4 cathode maintain over 94 mAh g−1 capacity retention after 300 cycles. This research presents an innovative Zn anode structure and extendable prestoring metallic Zn method for aqueous Zn‐ion batteries.

AbstractObjectives(1) To investigate sex differences in molar wear in known‐age Cayo Santiago rhesus macaques (Macaca mulatta) and, (2) To explore sex differences in body weight and molar eruption timing as factors influencing sex differences in molar wear.Materials and methodsData set I comprises wear scores, ages and body weights of 212 living monkeys included in the 1985 roundup. Data set II consists of molar wear measurements taken on 2D images of 103 of these monkeys' dental remains. Ordinal logistic regression was used to analyze the first data set. General linear models were used to analyze the second.ResultsMales generally exhibited more wear than females at equivalent chronological ages, though results varied by tooth type for the second data set. Male body weight in the full 1985 living sample was significantly related to dental wear, when age was taken into account; however, when males less than 8 years of age were eliminated from the sample, the association between dental wear and weight became statistically insignificant. Analysis of the second data set suggested no statistically significant sex difference in dental wear for third molars, despite the approximately 2 year sex difference in eruption age for this tooth type.DiscussionThis study suggests that body weight in males might be a predictor of dental wear and that if it is, body weight might also influence sex differences in dental wear. Sex differences in dental eruption timing do not appear to explain sex differences in dental wear in this sample.

AbstractThe development of high‐performance coatings for concrete structures is essential to ensure their durability and service life. However, most of the proposed developed strategies suffer from various limitations, especially regarding the wear and biological‐corrosion resistances of the coatings. This work reports a facile and efficient method to prepare effective composite coatings by nano‐modification, in which the intercalated composites play structural and functional roles in the corrosion, wear, and biological‐corrosion resistances. An in situ assembly synthesis was used to prepare the intercalated composites. The composites exhibited an innovative alternating skateboard structure and a functional composition. The silane‐emulsion modified with the composites was prepared and coated on the mortar surface to systematically study its performance at the concrete interface. The results indicate the good dispersion stability of the innovative α‐ZrP composites in the silane emulsion and their significant enhancement of the silane coatings' ability to improve the durability of marine concrete. The mechanisms of performance improved by the prepared composites through their unique lamellar structure and interlamellar silver‐nanoparticle composition were also examined. The prepared composite coating exhibits a new strategic approach to solve problems associated with concrete applications and provides technical guidance for surface protection of marine concrete structures.

Published: March 2022

AbstractThe reaction of N‐substituted benzimidazole with 4‐bromobutyronitrile gives the corresponding benzimidazolium salts as N‐heterocyclic carbene (NHC) precursors. Silver(I) carbene complexes are synthesized by the reaction of the corresponding benzimidazolium salts with Ag2O in dichloromethane. These new NHC precursors and Ag–NHC complexes were characterized by spectroscopy techniques and also screened for their antibacterial activities against the standard bacterial strains Escherichia coli, Pseudomonas aeruginosa, Acinetobacter baumannii, Klebsiella pneumoniae, Staphylococcus aureus, methicillin‐resistant Staphylococcus aureus, and Enterococcus faecalis, and the standard fungal strains Candida albicans and Candida glabrata, and promising results were achieved. The compounds were also analyzed by density functional theory (DFT)/time‐dependent DFT and docking methods.

AbstractMicrobes make a remarkable contribution to the health and well‐being of living beings all over the world. Interestingly, pterin deaminase is an amidohydrolase enzyme that exhibits antitumor, anticancer activities and antioxidant properties. With the existing evidence of the presence of pterin deaminase from microbial sources, an attempt was made to reveal the existence of this enzyme in the unexplored bacterium Agrobacterium tumefaciens LBA4404. After, the cells were harvested and characterized as intracellular enzymes and then partially purified through acetone precipitation. Subsequently, further purification step was carried out with an ion‐exchange chromatogram (HiTrap Q FF) using the Fast‐Protein Liquid Chromatography technique (FPLC). Henceforward, the approximate molecular weight of the purified pterin deaminase was determined through SDS–PAGE. Furthermore, the purified protein was identified accurately by MALDI‐TOF, and the sequence was explored through a Mascot search engine. Additionally, the three‐dimensional structure was predicted and then validated, as well as ligand‐binding sites, and the stability of this enzyme was confirmed for the first time. Thus, the present study revealed the selected parameters showing a considerable impact on the identification and purification of pterin deaminase from A. tumefaciens LBA4404 for the first time. The enzyme specificity makes it a favorable choice as a potent anticancer agent.

Published: March 2022

AbstractIn this work, a new open‐tubular capillary electrochromatography (OT‐CEC) column was prepared using β‐cyclodextrin covalent organic framework (β‐CD COF) as a stationary phase. Polydopamine was used to assist fabrication of β‐CD COF on an inner wall of a fused‐silica capillary. The coating layer on the capillary was characterized by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). Electroosmotic flow (EOF) was also studied to evaluate the variation of the inner wall of immobilized columns. Furthermore, the chiral separation effectiveness of the fabricated capillary column was evaluated by CEC using enantiomers of several related proton pump inhibitors as model analytes, including omeprazole, lansoprazole, pantoprazole and tenatoprazole. The effects of bonding time and concentration of β‐CD COF, the type, concentration and pH of buffer, applied voltage were investigated to obtain satisfactory enantioselectivity. In the optimum conditions, the enantiomers of four analytes were resolved within 15 min with resolutions of 1.63–2.62. The relative standard deviation values for migration times and resolutions of the analytes representing intraday and interday were less than 6.75% and 4.24%, respectively. The results reveal that β‐CD COF has great potential as chiral‐stationary phases for enantioseparation in CEC.
Distribution characteristics of pulverized coal and stress–gas pressure–temperature response laws in coal and gas outburst under deep mining conditions

Published: March 2022

AbstractDeep mining will increase the likelihood of coal and gas outburst accidents and do harm to the safety of coal mining. In this study, a coal and gas outburst experiment under deep high‐stress conditions was carried out and stress–gas pressure–temperature response laws in coal and rock surrounding the burst hole were evaluated. The experimental results showed that the stress response around the burst hole was intense and stress variation decreased as distance from the position to burst port increased. The gas pressure in the coal decreased sharply and oscillated several times during the burst process. The maximum rebound range was 0.05 MPa during this process. The decreasing rate of gas pressure reduced with the increase of the position‐burst port distance. The temperature response near the burst port was stronger than peripheral area. The gas internal energy was still the main energy source of coal and gas outbursts, accounting for 75% of the total energy, and played a key role in the burst process. The contribution of elastic potential energy was 22% under deep high‐stress conditions in this study. Based on the analysis of burst energy, the gas and stress were key factors of an outburst.
Does the topographic data source truly influence the routing modelling of debris flows in a torrent catchment?
Authors: Boreggio Mauro , Bernard Martino , Gregoretti Carlo 
Published: March 2022

AbstractTo cope with debris‐flow hazards, a common practice is the mapping of threatened areas through routing models. Considering the primary role of topography in affecting the mobility of gravity‐driven flows, its proper representation through digital elevation models (DEMs) is a requirement in routing modelling applications. The ‘quality’ of DEMs mainly depends on the quality, resolution and spatial arrangement of the topographic measurements (i.e. on the employed survey technology). Nevertheless, no attempt to systematically evaluate the influence of the topographic data source on the behaviour of routing models has been carried out. To address this, we initially assess the performances of both terrestrial‐ (i.e. global navigation satellite system, GNSS) and airborne‐based (i.e. full‐waveform LiDAR and structure‐from‐motion, SfM digital photogrammetry) survey technologies in characterizing the topography of a debris‐flow channel. Afterwards, we investigate whether the topographic data source can effectively influence the behaviour of a geographic information system (GIS)‐based cell routing model. Regarding the assessment of the survey technologies performances, the ‘standard’ statistic‐based approach indicated that GNSS and full‐waveform LiDAR can provide an accurate digital representation of the gully. However, the analysis of the shapes stressed that the most faithful and finer reproduction of the topographic singularities is yielded by the photogrammetrically reconstructed surface due to the extremely high data source resolution. Furthermore, the pairwise comparison of derived elevation models pointed out that meaningful discrepancies among tested survey technologies can be detected in morphologically complex areas because of the inherent limits of the terrestrial‐based method. Here, this research showed how these discrepancies have the potential to affect simulated flow dynamics, even if not in a meaningful way from a risk planning and management point of view. Overall, it appears that the topographic data source does not truly represent a determining factor in modelling applications of channelized debris‐flow routing.

Published: March 2022

Abstract
The present study investigated the occurrence and distribution of polycyclic aromatic hydrocarbons (PAHs) and phenolic endocrine-disrupting compounds (PEDCs), including bisphenol A (BPA), 4-nonylphenol (4-NP), and its monoethoxylate (NP1EO) and diethoxylate precursors in marine sediments in an Arctic fjord (Svalbard, Norway). The contribution of different local sources of contamination was also evaluated, together with a risk assessment for the marine environment. Samples were collected during two consecutive summer seasons (2018 and 2019), and target contaminants were analyzed with gas chromatography–mass spectrometry (MS) and high-performance liquid chromatography–MS/MS. The results showed no statistical differences between total PAH concentrations measured in 2018 (mean value 53.7 ± 54.3 ng/g) and 2019 (mean value 58.1 ± 63.6 ng/g). Low-ring (three or four rings) PAHs were the most abundant congeners, and single PAH ratios indicated a predominance of petrogenic sources (i.e., coal and liquid fossil fuel combustion). Nonylphenols and BPA showed a significant decrease in 2019 compared to 2018; 4-NP and NP1EO prevailed in both years, particularly in sediments close to the Ny-Ålesund research village. Overall, the results indicate that local anthropic activities are the major source of contamination in the Kongsfjorden ecosystem, but also melting waters from glaciers in the summer season can play an important role as a secondary source of pollutants previously trapped in ice. Comparison between our data and empirical and mechanistic indices derived from sediment quality guidelines suggests that the occurrence of PAHs and PEDCs in sediments does not currently pose a risk for this Arctic ecosystem, but further investigation is needed on the spread of hazardous contaminants and their effects on these fragile environments.

Effects of spray droplet size on pronamide control of Poa annua
Authors: Ignes Martin , Tseng Te‐Ming P. , de Castro Edicarlos , Wilber Amy L. , McCurdy James D. 
Published: March 2022

AbstractAnnual bluegrass (Poa annua L.) is a problematic weed in turfgrass that has evolved resistance to 12 different herbicide sites of action. The mitotic inhibiting herbicide pronamide has both pre‐ and postemergence activity on susceptible annual bluegrass populations, but on certain resistant populations, postemergence activity is hypothetically compromised due to lack of root uptake or due to an unknown foliar resistance mechanism. Spray droplet size may affect foliar and soil deposition of pronamide, thus potentially explaining variation in population control or differential shoot and root uptake. Greenhouse experiments were conducted to quantify pronamide, flazasulfuron, and pronamide + flazasulfuron (a common tank mixture) deposition on annual bluegrass as affected by spray‐droplet size. Five droplet sizes (200, 400, 600, 800, and 1,000 μm) were sprayed in an enclosed spray chamber on two‐ to three‐leaf stage annual bluegrass plants. Fluorescent dye was added to each treatment solution to quantify the effects of herbicide and spray droplet size on herbicide deposition. Results indicate that spray droplet size affects deposition of pronamide and flazasulfuron, applied alone and in combination, on annual bluegrass. The highest foliar deposition was produced with 400‐μm spray droplets in pronamide treatments and with 200 μm spray droplets in flazasulfuron and pronamide + flazasulfuron treatments. The addition of flazasulfuron to pronamide did not affect herbicide deposition when compared with pronamide‐alone treatments. Results suggest that 200‐ to 400‐μm spray droplets are optimal for foliar deposition of pronamide. Alternatively, larger droplet sizes may facilitate better soil deposition of pronamide where root uptake is optimal.

AbstractObjectivesIn this study, the role of change in tumor stiffness between pre‐ and post‐two cycles of neoadjuvant chemotherapy (NACT) measured by Acoustic Radiation Force Impulse (ARFI) imaging for predicting the response to NACT in breast cancer was analyzed.MethodsFifty‐two adult women with biopsy‐proven locally advanced breast cancer and early‐stage breast cancer who received NACT followed by either modified radical mastectomy or breast conservation surgery were included in the study. Tumor stiffness represented by shear wave velocity (SWV) in meter per second by ARFI imaging was measured before and after two cycles of NACT. Participants were categorized into responders and nonresponders based on pathological response assessment from the postoperative specimen. The association of change in tumor stiffness between pre‐ and post‐two cycles of NACT with final pathological response status was assessed.ResultsThe mean change in SWV before and after completion of two cycles of NACT was 0.42 ± 0.16 and 0.17 ± 0.11 m/s in responders and nonresponders, respectively, and this difference was proven to be statistically significant (p < 0.001) suggesting that tumors that exhibit a larger reduction in tumor stiffness, respond better. An SWV reduction cut‐off of 0.295 m/s between baseline and post‐two cycles of NACT was also arrived at, which can discriminate between responders and nonresponders with a sensitivity and specificity of 88% and 83%, respectively.ConclusionDifference in tumor stiffness measured by ARFI imaging before and after two cycles of chemotherapy can be used as a reliable early predictor of response to chemotherapy in breast cancer.

Published: March 2022

AbstractUpward of 80% of Black people speak some variant of African American English (AAE). The counseling profession is a language‐oriented form of help seeking, yet the relevance of linguistic diversity in a counseling context is largely absent from scholarly literature. Using Critical Race Theory as a theoretical framework, the authors provide a definition of AAE, as well as historical and sociopolitical contextual information about AAE. Important clinical implications for working effectively with AAE speakers are identified.

Published: March 2022

AbstractBACKGROUNDThe physicochemical characteristics, antioxidant properties, and bacterial profiles of Heterotrigona itama, Apis dorsata, and Apis mellifera honey of Malaysian origin were studied and the results were assessed using Pearson correlation analysis and canonical correspondence analysis (CCA).RESULTSThe analysis showed that the Mellifera honey was characterized by high total sugar content (717.5 g kg−1); the Itama honey was characterized by high free acidity (347.5 meq kg−1); and the Dorsata honey was characterized by high radical scavenging activity (RSA; 69.3%RSA), total phenolic content (TPC; 1284.5 mg GAE kg−1) and hydroxymethylfurfural (HMF; 51.5 mg kg−1). Pearson correlation analysis showed that the TPC was positively correlated with HMF as well as RSA. The bacterial profile of Mellifera honey was significantly less diverse than Itama and Dorsata honey. Mellifera and Itama honey seemed to harbour a significant abundance of lactic acid bacteria, with relative abundance of 0.339 and 0.195, which suggests that it possesses probiotic potential. The Dorsata honey, however, contained pathogenic Clostridium genus, constituting 5% of its bacterial profile.CONCLUSIONThe characteristic properties of the three investigated honey, Itama, Dorsata, and Mellifera were identified. The distinctive characteristics of the honey varieties informed the development of appropriate processing strategies for retaining the beneficial qualities of raw honey. It is hoped that the results of this study will shine light on Malaysian honey in a highly competitive global market. © 2022 Society of Chemical Industry.
